How to select materials in stamping parts
Due to the fact that the operation of the elastic unloading mold is more convenient than the fixed unloading mold, the operator can see the feeding action of the strip in the mold, and the elastic unloading plate applies flexible force to the strip during unloading, without damaging the surface of the workpiece. Therefore, in actual design, the elastic unloading plate should be used as much as possible, and only when the unloading force of the elastic unloading plate is insufficient, the fixed unloading plate should be used instead. The mold used for stamping parts depends on the size of the unloading force, with material thickness being the main factor to consider, whether it uses an elastic pressure unloading plate or a fixed unloading plate.
The hardness testing of stamping parts adopts a Rockwell hardness tester. Small, complex shaped stamping parts can be used to test flat surfaces that are too small to be tested on ordinary desktop Rockwell hardness testers. Alloy stamping parts are the most commonly used parts in the fields of metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or form metal plates and strips. Its application range is very broad.
Stamping parts processing includes processes such as punching, bending, deep drawing, forming, and finishing. The materials used for stamping parts processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plate, galvanized plate, tinplate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.
Hardness Testing of Stamping Materials
The main purpose of hardness testing for stamping materials is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing processes require different hardness levels of sheets. Aluminum alloy plates used for stamping parts processing can be tested using a Vickers hardness tester. When the material thickness is greater than 13mm, a Babbitt hardness tester can be used instead. Pure aluminum plates or low hardness aluminum alloy plates should use a Babbitt hardness tester.
