Metal stamping parts hardness testing using Rockwell hardness tester. Small, complex-shaped stampings that can be used to test small flat surfaces can not be detected on a common benchtop Rockwell hardness tester. PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stampings. Alloy stamping is metal processing, machinery manufacturing the most commonly used parts. Stamping parts processing is the use of mold separation or forming of the metal plate processing methods. Its application is very broad.

Stamping parts processing, including blanking, bending, drawing, forming, finishing and other processes. The materials for stamping are mainly hot rolled or cold rolled (mainly cold rolled), such as carbon steel, alloy steel, spring steel, galvanized steel, tinplate, stainless steel, copper and copper alloy Board, aluminum and aluminum alloy plate.

1. Stamping material hardness testing

The main purpose of stamping material hardness testing is to determine whether the purchase of the sheet metal annealing degree is suitable for subsequent stamping parts to be processed, different types of stamping parts processing technology, the need for different hardness levels of the plate. Aluminum alloy sheet for stamping parts processing available Webster hardness tester, material thickness greater than 13mm can be changed to Barcol hardness tester, pure aluminum or low hardness aluminum alloy plate should be used Barcol hardness tester.

2, stamping die hardness testing

The main material of stamping die mold steel (including tool steel and high-speed steel), and sometimes also use cemented carbide.

Stamping die is usually required to have a high hardness and wear resistance, heat treatment is essential.
