Metal stampings testing is divided into stamping material testing and stamping die testing, metal stampings are generally selected Rockwell hardness tester. Small, stamped parts with a messy shape can be used to test the plane is very small, can not be detected on a general bench Rockwell hardness tester. The PHP series Portable Rockwell Hardness Tester is ideal for testing the hardness of these stamped parts. Alloy stampings are the most commonly used parts in the metal processing and mechanical manufacturing sectors. Stamping parts processing is the processing method that uses the mold to make the metal plate segregation or forming. Its use is very large.
1, hardware stamping parts of the hardness test
The hardness test of the stamping material information, the chief intention of the metal stampings processing factory is to determine whether the degree of annealing of the purchased sheet metal is suitable for the subsequent stamping part processing. Different stamping parts processing technology, the demand is not the same hardness Grade plate. The aluminum alloy plate used for stamping parts processing can be tested with the Vickers hardness tester. When the data thickness is greater than 13 mm, the Brinell hardness tester can be used. For the pure aluminum plate or the low hardness aluminum alloy plate, the Brinell hardness tester should be used.
2, hardware stamping die hardness testing
The primary data for stamping parts is die steel (including tool steel and high speed steel) and sometimes carbide.
Stamping parts generally require high hardness and wear resistance, and heat treatment is essential.
