Metal stamping parts

Metal stamping

Metal stamping is really a manufacturing process in which a metal stamping die or a series of metal stamping dies are utilized to form sheet metal into three-dimensional dimensional shaped workpieces. It's used in a variety of industries, such as: automotive and household appliances. Automotive stampings are a fundamental part of the metal stamping industry. This type of processing allows for extremely powerful forming of sheet metal. The metal stamping dies are mounted on a press, which forms one workpiece per stroke.

Features

(1) The dimensional accuracy of the stamped part is guaranteed through the die, that has the sign of being one mould, so the quality is stable and interchangeable. The die guarantees the dimensional and shape accuracy from the stamped part and doesn't generally damage the top quality of the stamped part, as the lifetime of the die is generally long. (2) Because of the use of mould processing, it is possible to obtain parts with thin walls, light weight, good rigidity, high surface quality and complex shapes that cannot be manufactured by other processing methods or take time and effort to fabricate. Stamping can establish parts having a a lot of different sizes and complex shapes, for example stopwatches for clocks and watches, longitudinal beams and coverings for cars, etc. Together with the cold deformation and hardening effect of the material during stamping, the force and rigidity of stamping are higher. (3) The stamping process generally doesn't need heating from the blank, nor does it cut a lot of metal like the cutting process, so it doesn't only save energy but also saves metal, as the stamping generally does not generate chips and scraps, the intake of materials are less, with no other heating devices are required, so it's a material-saving and energy-saving processing method, and the cost of stamping parts is gloomier. (4) For ordinary presses, dozens of pieces can be achieved each minute, while high-speed presses can produce hundreds or thousands of pieces per minute. The production efficiency of stamping processing is high, and the operation works and easy to understand mechanization and automation. It is because stamping relies upon the punching die and stamping equipment to complete the process, the amount of strokes for ordinary presses can reach a large number of times each minute, high-speed presses can reach hundreds of times per minute or maybe more than the usual thousand times, and each stamping stroke could get a punching part.

The quality of the mold cooling system directly affects the martensite

The heat of the parts can be roughly divided into three directions: first, most of the heat is diffused into the cooling system through the mold, and the heat is taken away by the convection heat exchange effect of the cooling water. There is also a part of the heat directly diffused into the atmosphere through the convection heat exchange between the mold surface and the air and heat radiation. Only a small part is left inside the part due to the thermal equilibrium between the part and the mold. The quality of the mold cooling system directly affects the martensite transformation during the quenching process in the mold. If the martensite transformation cannot be carried out completely, a bainite structure will be generated inside the workpiece. Brittleness will greatly affect the mechanical properties of the parts. The design requirements of the mold cooling system mainly include the following three aspects: cooling rate, cooling uniformity, and heat transfer stability. In order to meet these requirements, the parameters such as the diameter, distribution position, shape and initial flow rate of the cooling pipe need to be reasonably designed. For example, H. Karbasian abroad studied the influence of different processing methods of cooling pipes on cooling capacity. Naderi et al. compared the effects of different cooling media on the processing quality of parts, and concluded that the cooling effect of nitrogen is better. Wang Liying and others in our country solved the critical water flow rate of the cooling system (0.75m/s) by establishing a mathematical model. Using the Fluent simulation software to carry out numerical simulation on the cooling system, it is concluded that in the design of the cooling system, the number of pipes and the design of the corners should be reduced as much as possible and the diameter of the pipe should be appropriately increased to ensure the cooling effect.

High-strength steel plates and ultra-high-strength steel plates have high toughness, strong deformability and very little springback problems when heated to full austenitizing temperature. For the design of hot stamping molds, we can mainly consider how to reduce the flow resistance of the metal, so that the metal can be completely filled into the mold cavity. Since the size and shape of the working surface of the mold are determined by the geometric size of the workpiece, the surface accuracy is guaranteed by the manufacturing accuracy, mainly considering the radius of the mold, the gap between the convex and concave molds, the drawing ribs, the guiding and positioning devices, etc. 2.3.1 Determination of die fillet radius The stamping process can be divided into a separation process and a forming process according to the deformation properties. The die fillet radius needs to be determined according to different processes. For separation processes such as blanking and punching, sufficiently sharp convex and concave die edges are required. When the edges of the convex and concave molds are blunt, large burrs will be generated at the notch of the part, which affects the dimensional accuracy of the part. For forming processes such as deep drawing and bending, the fillet radius of the male and female dies cannot be too small. If the fillet radius is too small, it will affect the flowability of the material and cause thinning and cracking of the sheet. For the determination of the fillet of the mold, it is necessary to comprehensively consider the factors such as the processing procedure and the deformation characteristics of the part. Without affecting the Molding Process Manufacturers performance of the part, the radius of the fillet can be appropriately increased to improve the fluidity of the metal in order to obtain a high-quality system. Pieces. 2.3.2 Determination of the gap between the male and female molds The mold gap can be divided into the mold clamping gap on the working surface of the male and female molds, and the gap between the blank holder and the female mold. Among them, the size of the gap between the convex and concave molds directly affects the cooling effect of the mold. Increasing the mold clamping gap can effectively increase the fluidity of the sheet, reduce the friction between the sheet and the surface of the mold, and increase the life of the mold. When the mold clamping gap is too large, due to the shrinkage of the sheet during the cooling process, the gap between the sheet and the mold is generated, which reduces the heat transfer coefficient of the sheet and the mold, which affects the cooling capacity of the mold. When the mold clamping gap is too small, although the cooling effect can be improved, the friction between the sheet and the mold is increased, and the service life of the mold is reduced. 2.3.3 Design and selection of other structures In addition to the above structures, other structures have varying degrees of influence on the dimensional accuracy and surface accuracy of the parts: ①Drawbeads. Drawbeads usually refer to the protrusions on the die blanking surface or blank holder, and have the effects of increasing deformation resistance, controlling the direction of sheet flow, and preventing wrinkling. In hot stamping, for parts with simple shapes, adding drawbeads will cause cracking and other problems. ②Guide device. The guide device mainly includes a guide sleeve and a guide post, etc. Its function is to ensure the relative position of the upper and lower molds and the uniformity of the mold clamping gap, which has a significant influence on the cooling effect of the mold and the dimensional accuracy of the parts. ③ Positioning device. In hot stamping, the positioning of the sheet material is mainly ensured by the positioning device on the mechanical arm, so I will not discuss it too much here.

With the increasing pollution of automobiles, how to reduce the environmental pollution by realizing the lightweight of automobiles under the premise of ensuring safety has become a hot issue. Hot stamping technology as a key technology that uses high-strength steel and ultra-high-strength steel for automobile lightweight has attracted widespread attention. As an important part of hot stamping, the design accuracy and manufacturing accuracy of hot stamping dies have always been the main factors limiting the technology of hot stamping. Although people have made more systematic design requirements for the selection of mold materials, cooling system design, and mold structure design, there are still many problems in the processing quality of the parts, and subsequent processing is still required. In the research and development of hot stamping mold materials, cooling system design, mold structure optimization, etc., people still need to explore.

The advantages of metal stamping parts and some related knowledge

As a kind of parts with a wide range of English, high precision and high demand, metal stamping parts play a great role in the use of medical equipment. The advantages of metal stamping parts are numerous, and the manufacturing process requirements are high. Today, let's take a look at the advantages of metal stamping parts, as well as some information about the stamping process.

The advantages of metal stamping parts:

1. During metal stamping, the size and shape accuracy of metal stamping parts are guaranteed by the mold, which generally does not destroy the surface quality of the stamping parts, and the life of the mold is generally long, so the quality of metal stamping is stable.

2. Metal stamping can process parts with a wide range of sizes and complex shapes, such as stopwatches as small as clocks, as large as automobile longitudinal beams, covering parts, etc., plus the cold deformation hardening effect of the material during metal stamping, metal stamping Strength and stiffness are high.

3. The processing and production efficiency of metal stamping parts is high, and the operation is convenient, and it is easy to realize mechanization and automation. This is because metal stamping relies on dies and stamping equipment to complete the processing. The number of strokes of ordinary presses can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute. It is possible to get a punch.

4. Metal stamping generally does not generate chips and scraps, consumes less material, and does not require other heating equipment, so it is a material-saving and energy-saving processing method. This also makes the cost of metal stamping parts lower.

From the advantages of metal stamping parts, we can have a more detailed understanding of it. It can be seen that metal stamping parts have the characteristics of high strength and rigidity, high dimensional accuracy, good surface quality, and less material consumption.

What are the main measures to reduce the cost of manufacturing metal stamping parts?

1. Improve the rationalization level of the process.

2. Improve the level of mold design, reduce the process, and improve the life of the mold.

3. Reduce costs by improving the automation and high-speed level of the stamping process.

4. Design molds for simultaneous processing of each workpiece.

5. Take the method of improving the utilization rate of materials to reduce the cost.

After understanding the advantages and cost-saving measures of metal stamping parts, let's learn more about the stamping process of metal stamping parts. According to the total deformation properties of the material, the stamping process of metal stamping parts can be roughly divided into two categories:

1. Separation process: Under the action of external force, the stress of the deformed part exceeds the strength limit of the material, and the sheet breaks and separates.

2. Plastic deformation process: Under the action of external force, the stress of the deformed part exceeds the yield limit of the material, but when the strength limit is not reached, only a plastic deformation table is generated to obtain a certain shape and size.

Metal stamping parts play an important role in the current social science and technology industry and have made great contributions to the progress of science and technology. The development of metal stamping parts has a positive role in promoting the development of related industries. If you have questions about metal stamping parts, please contact us for inquiries!

The role of stretch bending machine in production of auto parts

Stretch bending machine is a stamping process that bends metal sheets, pipes and profiles into workpieces with a certain curvature, shape and size, and plays a pivotal role in the production of auto parts. A stretch bending machine is used to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and the surface roughness of the workpiece is reduced.

Bending is a commonly used bending method. Most of the equipment used is a general mechanical press or hydraulic press, but also a bending press. The commonly used bending equipment is a plate bending machine. The three-roll plate bending machine determines a circle according to three points. The reason is to continuously bend the slab. The three-roller bending machine has two driving rollers (fixed) and a pressing roller (adjustable). Adjusting the upper and lower positions of the pressing roller can change the relative distance between it and the driving roller.

When drawing and bending, the plate is placed between the driving roller and the pressing roller, and the driving roller rotates in the forward and reverse directions to make the plate reciprocate. By adjusting the pressing roller to gradually press it down, the plate can be bent into a cylindrical surface with a required curvature, a conical surface and a hyperboloid with a smaller curvature.

How to choose the loading mode of the stretch-bending machine? The basic principle of the aluminum profile stretch-bending forming is that the stretch-bending die and the table are fixed, and the arm stretched profile rotates around the stretch-bending die, so that the profile wool is produced under the action of the tension and the bending moment. Plastic deformation, and gradually fit the mold, so as to obtain the required shape of the part.

The characteristics of stretch-bending parts are that the radius of curvature is relatively large, the springback is relatively large, and the curvature changes in the axial direction. Aluminum profile bending is widely used in the aerospace, automobile, construction and high-speed train industries for the forming of curved parts, such as fuselage, wing stiffeners and skeletons, curved house skeletons, curved door frames, window frames, and train heads , The roof profile support parts, window frames, curved door frame skeletons, and stretch-bent parts play an important role in the production of auto parts in my country.

Ningbo Shengyaqi Auto Parts Co., Ltd. was established in 2005, focusing on the research, development and manufacturing of special tools and equipment. Our engineers usually have 5-10 years of experience in the professional field. The stretch bending machine produced is well-known at home and abroad and is very popular.

Stamping Technology and Die Design of Stainless Steel Flange

The stamping industry is an industry that touches an extremely wide range of areas and deepens into every aspect of manufacturing. such as stainless steel flange. Stamping in foreign countries is called sheet metal forming. Stamping is to rely on the press and die on the plate, strip, pipe and profiles, such as the imposition of external forces to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) and carbon steel flange forming processing methods.

Stamping and forging the same plastic processing (or pressure processing), collectively known as forging. The stamping billet is mainly hot-rolled and cold-rolled steel and steel strips. Among the world’s steel, $number is the plate, most of which is pressed into the finished product. Stamping is sometimes called sheet metal forming, but slightly different. The so-called sheet metal forming refers to the use of plates, thin-walled tubes, thin profiles, such as raw materials for plastic processing as the forming method collectively known as sheet metal forming, at this time stamping skills common sense, thick plate deflection of ordinary not focus on thinking.

Stamping die is called die. Punching die is a special tool for processing material (metal or nonmetal) in batches into the required punching parts. Die in the flange stamping is very important, not meet the requirements of the die, batch stamping production is difficult to carry out; no advanced punching die, advanced stamping process can not be achieved. Stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing, only they can be combined to draw stampings. Cold stamping parts are generally no longer machined by cutting, or require only a small amount of cutting. The precision and surface state of hot stamping parts are lower than that of cold stamping parts, but they are still better than castings and forgings.

Compared with castings and forgings, stamping parts have the characteristics of thin, uniform, light and strong. Stamping can make other methods difficult to manufacture with reinforced, undulating or flanging workpiece to improve its rigidity. Due to the use of precision molds, workpiece accuracy can reach micron level, and repeat the high precision, specifications consistent, you can punch hole nest, convex table and so on.

Tianhe shrimp elbow manufacturers

Tianhe shrimp elbow manufacturers stamping forming elbow is a forming process that has been used for mass production of seamless elbow. In the production of elbow with common specifications, it has been replaced by hot push method or other forming process. However, in some elbow specifications, attention should be paid to the slag inclusion in welding when connecting the stamping elbow with the pipe. Slag inclusion means slag inclusion in non-metallic materials. The main reason for this phenomenon is that the groove processing on the pipe or elbow stamping products is not correct, that is, the angle is too small. This is one reason, and another reason is that the current during welding is too small and the viscosity of slag is too high. Because the viscosity is too high, the slag can not float to the surface, which leads to slag inclusion. In addition, the energy rate of torch flame is not enough when gas welding, and the cleaning work of workpiece is not done well when welding and stamping elbow and pipeline. The use of oxidation flame, or in other words, the swing amplitude is too small, and the slag is not pulled out in time, which all cause welding slag inclusion. After the coating block on the electrode fell off, it was not fully melted. There are many layers of weld, is also one of the reasons. If there is slag inclusion during welding. Because the production quantity is small, the wall thickness is too expanded metal mesh machine suppliers thick or too thin. The product is still in use when it has special requirements. The elbow is made by Tianhe shrimp elbow manufacturer with the same outer diameter as the elbowThe blank is directly pressed in the die with a press. Before stamping, the tube blank is placed on the lower die, and the inner core and end die are loaded into the tube blank. The upper die moves downward and begins to press. The elbow is formed by the constraint of the outer die and the support of the inner die. Compared with the hot push process, the appearance quality of stamping forming is not as good as the former; the outer arc of the stamping elbow is in the tensile state, and there is no extra metal in other parts to compensate, so the wall thickness at the outer arc is reduced by about 10%. However, due to its application, the purpose is to pipe bending machine china eliminate the internal stress produced by quenching, reduce the hardness and brittleness, so as to obtain the expected mechanical properties. Tempering can be divided into high temperature tempering, medium temperature tempering and low temperature tempering. Tempering is usually used with quenching and normalizing. (1) quenching and tempering treatment: the heat treatment method of high temperature tempering after quenching is called quenching and tempering treatment. High temperature tempering refers to tempering between ℃. Quenching and tempering can adjust the properties and materials of steel to a great extent. Its strength, plasticity and toughness are good, and it has good comprehensive mechanical properties. (2) aging treatment: in order to eliminate the size and shape changes of precision measuring tools or molds and parts in long-term use, the workpiece is often reheated to ℃ for 5-20 hours after low-temperature tempering (low-temperature tempering temperature ℃) before finishing. This kind of treatment is called aging to stabilize the quality of precision parts. It is very important to carry out aging treatment on steel components under low temperature or dynamic load to eliminate residual stress and stabilize microstructure and size of hot pressed elbow. The annealing of hot pressed elbow will heat the hot pressed elbow to a certain temperature and keep it for a period of time. Single piece production and low cost features, so stamping elbow workers useThe heating method depends on the forming product requirements and energy conditions. Stamping forming elbow is a forming process which has been used in batch production of seamless elbow. It has been replaced by hot push method or other forming process in the production of elbow with common specifications. However, in some elbow specifications, due to less production quantity, too thick or too thin wall thickness. The product is still in use when it has special requirements. The tube blank with the same outer diameter as the elbow is used for the stamping forming of the elbow, and the press is used to directly press the tube blank in the die. Before stamping, the tube blank is placed on the lower die, and the inner core and end die are loaded into the tube blank. The upper die moves downward and begins to press. The elbow is formed by the constraint of the outer die and the support of the inner die. Compared with the hot push process, the appearance quality of stamping forming is not as good as the former; the outer arc of stamping elbow is in tensile state during forming, and there is no excess metal in other parts to compensate. Therefore, the wall thickness at the outer arc is reduced by about 10%. However, due to the characteristics of being suitable for single piece production and low cost, the stamping elbow process is mostly used for the manufacture of small batch and thick wall elbows. Yiduo is used for manufacturing small batch and thick wall elbows.

The best way to produce high-precision mould parts?

The mould component is simply a little thing from the mould, though it's inconspicuous, it's a fantastic effect. By way of instance, the ejector pin, once the metal stamping die functions, the workpiece that's punched out could not be discharged without it. The significance of the Precision Mold manufacturers can't be underestimated, so the design has to adapt to the usage of this mould and can be readily constructed and repaired. To be able to fulfill the necessities of the client, we have to possess high-precision processing gear, moreover, the following needs to be said from the procedure for fabricating also:

1. Choice of processing gear. Ahead of the mould design, the provider should fully consider its application in the processing of distinct precision gear. For the accuracy and dimensions of the mould components processing precision, pick the proper accuracy and rigidity of their production equipment. Tool selection. Decide on a tool using high wear resistance and higher reliability, and it's acceptable for high-precision machining and fortify tool administration. Temperature control. Improve the understanding of the operator's Custom Precision Metal Stamping , processing attributes and machine tool performance abilities. Regularly arrange the technical exchanges between the design department and the production department, and discover the issues in a timely way. It's required to set up the concept and direction method which unconditionally matches the specified machining precision in each single workshops.

The mould designer should have abundant experience in design and injection molding. For precision mould processing, the association between those influencing factors and injection requirements and its apparent things have to be considered, for example injection pressure and cavity pressure and fulfilling rate, injection melt temperature. Along with the mould temperature, mould construction and gate shape and supply, in addition to the cross-sectional subject of the gate, the wall thickness of this item, the material of reinforcing filler from the plastic substance, the crystallinity and orientation of this plastic substance and other aspects. The effect of the above mentioned factors also differs based on the plastic substance or other cast conditions like humidity, temperature, continuing crystallization, and adjustments in the injection molding system after molding.Among the variables impacting precision injection molding, molds would be the secret to obtaining precision vinyl products which satisfy quality demands. The plan of the mould, whether the mould layout is reasonable will immediately influence the grade of plastic solutions. Since the mould cavity size comes from the essential size of the plastic merchandise in addition to the shrinkage of the substance utilized, the shrinkage rate is frequently a value within the range recommended by the plastics maker or technology plastics guide, not just with the gate kind of the mould. The job of the gate is regarding the supply, and is about the crystal orientation (anisotropic) of this plastic, the form and dimensions of the plastic solution, and also the space and position of the gate. The key factors influencing the shrinkage of plastics comprise heat shrinkage, stage shift shrinkage, orientation shrinkage, compression shrinkage and elastic recovery, and such variables are about the molding requirements or operating terms of precision injection molded articles.Because the injection molding method is the practice of separating plastic out of strong (powder or pellet) to liquid (melt) to sound (merchandise ). Precision mold processing, from pellets to meltdown, from melting to merchandise, through the warmth area, flow area and density area. Under the joint action of those areas, different plastics (thermoset or thermoplastic, crystalline or amorphous, reinforced or unreinforced, etc.) have distinct polymer morphological and rheological properties. Any things which impact the above-mentioned"area" will definitely impact the mechanical and physical attributes, size, contour, accuracy and look quality of plastic products.Thus, the inherent connection between process variables and anti inflammatory properties, structural morphology, and plastics is illustrated by plastics. It's very important to examine these inborn connections to logically invent injection molding procedures, rationally design and fabricate molds based on drawings, and also choose injection molding equipment. Precision injection molding and regular injection molding also differ in injection pressure and injection rate. Precision injection molding frequently utilizes high pressure or ultra high pressure injection and higher speed injection to acquire a little molding shrinkage.

The precision in precision metal stamping mainly refers to the high precision of the mold, the high precision of the stamping machine, the high precision of the testing equipment, and the high precision of the final product. The output of precision stamping products is gradually increasing.

In recent years, the output of precision stamping parts has been increasing year by year, and the development is very rapid. Precision stamping parts technology has huge advantages in automotive engines and other fields, and has become an indispensable metal die casting technology in these fields. These advantages have been applied to the IT industry. Precision stamping parts technology has the characteristics of multiple varieties, material diversity, thin plate coils, large automated production batches, high precision, complex shapes, high technical content and high added value. In today's highly developed market economy, it has a very important position.

Precision stamping parts technology can not only manufacture small instrument parts, but also large parts such as automobile beams and pressure vessel heads; it can manufacture parts of general size grades and shapes, but also parts of precise and complex shapes. The outstanding features of stamping products, especially precision stamping products are:

1. The consistency of product quality is required, that is, the quality of all products of the same model is highly consistent, and all products of the same model are completely interchangeable;

2. Assembly suitability, that is, all parts must achieve a perfect fit with other various parts in assembly, especially the precision parts of high-precision electromechanical equipment, the required dimensional error is very strict;

China has now become the world's manufacturing center. In the past ten years, rapid development has been achieved in industries such as automobiles, communication electronics, and household appliances, which has led to rapid growth in the demand for metal stamping parts. Many multinational companies have transferred the manufacturing of complete machines to China, and at the same time they have also transferred supporting factories to China. The purchase of domestic accessories has also increased rapidly year by year, which has driven the rapid development of domestic related industries. In this context, the metal stamping industry, one of the basic manufacturing industries, has also achieved rapid development.

China’s precision stamping parts technology enterprises are mainly divided into two categories. The first category is a closed single supporting enterprise, which is mainly a stamping enterprise or factory that provides professional support for large-scale machine manufacturers, and mainly foreign-invested enterprises. Machine products supporting the production of parts and components, such enterprises generally do not participate in the market share competition outside the target machine plant, and their production capacity cannot be fully utilized. The second category is independent metal stamping companies, including specialized metal stamping parts manufacturers and small-scale stamping companies.

The development of precision stamping parts technology has a great effect on improving the production quality of related products and improving the technical level of the industry. Precision stamping parts technology will continue to develop towards a higher level, higher requirements, and higher standards.
