Inspection of metal stamping parts
The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stampings with complex shapes can be used to test the surface is too small to be detected on ordinary benchtop Rockwell hardness testers.
Stamping processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin-plated plates, stainless steel plates, copper and copper alloys plate, aluminum and aluminum alloy plate, etc.
The PHP series portable superficial Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in the fields of metal processing and machinery manufacturing. Stamping processing is a processing method that uses a mold to separate or form metal strips.
Its application range is very wide. The main purpose of hardness testing of stamping parts is to determine whether the annealing degree of purchased metal sheets is suitable for subsequent stamping parts processing. Different types of stamping parts processing technology require plates of different hardness levels.
The aluminum alloy plate used for stamping processing can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead. A pure aluminum plate or a low-hardness aluminum alloy plate should use a Barcol hardness tester.
