Hardness test of metal stamping parts Rockwell hardness tester is selected for hardness test of metal stamping parts. The small stamping parts with disordered shape can be used to test the small plane and can not be tested on the ordinary Rockwell hardness tester. Metal stamping processing includes stamping, zigzag, drawing, forming, finishing and other processes.

Hardness test of metal stamping parts

Rockwell hardness tester is selected for hardness test of hardware stamping parts. The small stamping parts with disordered shape can be used to test the small plane and can not be tested on the ordinary Rockwell hardness tester.

Metal stamping processing includes stamping, zigzag, drawing, forming, finishing and other processes. The processing materials of metal stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal plate and strip materials, such as carbon steel plate, alloy steel plate, tension spring steel plate, galvanized plate, tinplate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate, etc.

PHP series portable external 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 field of metal processing and mechanical manufacturing. Stamping parts processing is a processing method that uses die to separate or form metal strip. Its application plan is very broad.

The main purpose of hardness testing of stamping materials is to recognize whether the annealing degree of the purchased metal sheet is suitable for the stamping processing to be carried out later. Different kinds of stamping processing technologies need different hardness levels of sheet metal. The aluminum alloy plate used for stamping can be tested with a Vickers hardness tester. When the material thickness is greater than 13mm, the Vickers hardness tester can be used instead. The Vickers hardness tester shall be used for pure aluminum plate or low hardness aluminum alloy plate.

In the stamping industry, stamping is sometimes called sheet forming, but it is slightly different. The so-called sheet forming refers to the forming method of plastic processing with sheet, thin-walled tube, thin profile, etc. as raw materials. At this moment, the deformation in the direction of thick plate is generally not considered.
