What are the common problems in processing precision metal stamping parts?
Release time:2022-07-22Views:532


Stamping depends on the increase of external force of stamping machine and die, strip, pipeline and profile part, resulting in plastic deformation or separation, so as to obtain the workpiece with the required shape and size, including cutting, bending, drawing, forming, carding and other processes. Stamping process/die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only by integrating with each other can stamping parts be obtained. Precision metal stamping parts should meet the requirements of the industry and can be divided into many types according to the purpose and process characteristics.


Common problems in metal stamping processing include deformation and burr of precision stamping parts. Warpage, surface scratch, angular deformation, etc.; the deep part of the convex platform wrinkle, deep wall wrinkle, deep wall damage, cracking, etc., and uneven expansion.

Methods to deal with common problems: mold design should have reasonable punch and die clearance value, rounded radius and solution accuracy. When designing the bending die, effective measures should be taken to reduce the rebound in the die, and a reasonable arc should be designed to avoid bending. When deepening, the pressure edge should be used to avoid medium pressure; use proper lubrication to reduce deepening resistance and avoid mold adhesion or driving workpiece; use professional stamping oil that meets the process requirements.

Advantages of precision stamping:

1. Stamping has high production efficiency, convenient operation, and convenient mechanization and automation. This is because stamping is completed by stamping dies and stamping equipment. Generally speaking, the stroke of the press can reach dozens of times per minute, and the high-speed pressure can reach hundreds or even thousands of times per minute.

2. When stamping, because the die ensures the size and shape accuracy of the stamping parts, the surface quality of the stamping parts will not be damaged generally. The die is generally characterized by long service life, stable stamping quality and good interchangeability.

3. Stamping can process parts with larger categories and complex shapes, such as small stopwatches and large side beam etc. In addition, under stamping conditions, the cold deformation hardening strength and stiffness of the material is higher.

4. Stamping is a kind of energy-saving material, and energy-saving processing method. The cost of stamping parts is low, no slag, with low material cost, and do not need other heating equipment.
