Metal stamping inspection

The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the plane is very small, can not be tested on the ordinary desktop Rockwell hardness tester.

Stamping 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) sheet metal materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc.

The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are the most commonly used parts in metal processing and mechanical manufacturing. Stamping processing is a processing method that uses molds to separate or shape metal strips. Its application range is very broad.

The main purpose of the hardness test of stamping parts is to determine whether the annealing degree of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts processing techniques require plates of different hardness levels. The aluminum alloy plate used for stamping parts can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester.

In the stamping industry, stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method of plastic processing using sheet materials, thin-walled tubes, thin profiles, etc. as raw materials, which are collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.
