Top 7 Websites To Buy Stamping In The World

This is an article that introduces you to stamping parts. It includes the use of stamping parts, introduces you, and introduces some good stamping parts suppliers to help you gain some knowledge in purchasing stamping parts.

What is a stamping machine?

60 ~ 70% of the steel in the world is plate material, and most of them are finished products by stamping. The car body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, and iron core silicon steel sheet of electrical appliances are all stamped. There are also a large number of stamped parts in instruments, household appliances, bicycles, office machinery, household utensils and other products.

Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can make workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods to improve its rigidity. Due to the use of precision molds, the precision of the workpiece can reach micron level, and the repeatability is high, the specifications are consistent, and holes and bosses can be punched out.

Cold stamped parts are generally no longer cut or require only a small amount of cutting. The precision and surface condition of hot stamping parts are lower than cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is small.

Punching is an efficient production method. Using a compound die, especially a multi-stage progressive die, multiple stamping processes can be completed on one press to achieve the full range from strip unwinding, leveling, punching to forming and finishing. Automatic production. High production efficiency, good labor conditions and low production costs, generally hundreds of pieces can be produced per minute.

Stamping is mainly classified according to process, which can be divided into two major categories: separation process and forming process. The separation process is also called blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line, while ensuring the quality requirements of the separation section. The surface and intrinsic properties of the stamping sheet have a great impact on the quality of the stamped product. The thickness of the stamped material is required to be accurate and uniform; the surface is smooth, no spots, no scars, no abrasions, no surface cracks, etc .; the yield strength is uniform, no obvious Directionality; high uniform elongation; low yield ratio; low work hardenability.

What is metal stamping used for?

The stamping part is the production technology of the product parts with certain shape, size and performance by directly deforming the sheet in the mold by means of the power of conventional or special stamping equipment. Sheets, dies and equipment are the three elements of stamping. Stamping is a method of cold deformation of metal. Therefore, it is called cold stamping or sheet stamping, which is called stamping for short. It is one of the main methods for metal plastic processing (or pressure processing) and also belongs to material forming engineering technology.

Around 50 to 60% of Universal's steel is made of sheet metal, and most of this is a finished product that has been pressed. Automotive body, radiator, steam drum, container shell, motor, electrical appliances, silicon steel sheet, etc. are usually stamped. There are also a large number of stamped parts in products such as instruments and meters, household appliances, office rigidity, storage containers and so on. Stamping is an efficient copying measure. It adopts a compound die. The abnormality is a multi-stage progressive die. It can complete multiple stamping operations on a single press and automatically generate materials. The production speed is fast, the rest time is long, and the cost of copying is low. The collective can copy hundreds of pieces per minute, which is loved by many processing plants.

Stamping parts, castings, and forgings are strong, thin, uniform, light, and strong. Stamping can produce workpieces with reinforcement ribs, ribs, curling or flanging that are difficult to manufacture with a skilled hand diameter to improve its rigidity. Because the rough mold is rejected, the precision of the workpiece can reach micron level, and the precision is high, and the specifications are consistent. It can punch holes, bosses, etc. In actual production, technological tests similar to the stamping process, such as deep-drawing performance test and bulging performance test, are often used to check the stamping performance of the material to ensure the quality of the finished product and high pass rate.

What should I do if the stamping part is twisted?

⑴. Reasonable mold design. In the progressive die, the arrangement of the blanking order may affect the accuracy of stamping parts forming. For the blanking of small parts of stamping parts, generally, a larger area of punching blanking is arranged first, and then a smaller area of punching blanking is arranged to reduce the impact of the punching force on the forming of the stamping part.

⑵.Squeeze the material. Overcome the traditional mold design structure, open the material holding gap on the discharge plate (that is, when the mold is closed, the material can be compacted. At the key forming position, the discharge plate must be made into a block structure to facilitate the solution of long Grinding (pressing) loss caused by the pressing part of the discharge plate caused by time stamping can not compact the material.

⑶. Add strong pressure function. That is to thicken the blanking part of the discharge insert (the thickness of the normal discharge insert is H + 0.03mm) to increase the pressure on the material on the side of the die, thereby suppressing the stamping parts from turning and distortion during punching.

⑷. The edge of the edge of the punch is trimmed to be inclined or curved. This is an effective way to reduce the cushion. Reducing the buffer cutting force can reduce the tensile force on the material on the side of the die, thereby achieving the effect of suppressing overturning and distortion of the stamping part.

⑸. In daily mold production, care should be taken to maintain the sharpness of the punched convex and concave die edges. When the punching cutting edge is worn, the tensile stress of the material will increase, and the tendency of turning and twisting of the stamping part will increase.

⑹. Unreasonable or uneven gaps in punching are also the causes of stamping parts turning and distortion, which need to be overcome.

Conclusion:

The above is the website information of the best stamping parts we think.
