Cable manufacturer : How to test the hardware stamping parts?
Hardness testing of metal stamping parts uses Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes, which cannot be detected on ordinary benchtop Rockwell hardness testers.
Stamping parts processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin plate, stainless steel plates, copper and copper alloy Plate, aluminum and aluminum alloy plate.
The portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamped parts. Alloy stamping parts are the most commonly used parts in the field of metal processing and machinery manufacturing. Stamping is a processing method that uses a mold to separate or form metal sheets and strips.
The main purpose of hardness testing of stamping parts is to determine whether the degree of annealing of the purchased metal sheet is suitable for the subsequent stamping part processing. Different types of stamping part processing processes require different hardness levels of sheets. The aluminum alloy plate used for stamping parts processing can be tested with a Vickers hardness tester. When the thickness of the material is greater than 13mm, it can be replaced with a Barcol hardness tester. A pure aluminum plate or a low-hardness aluminum alloy panel should be used.
