Hardness testing of metal stampings uses Rockwell hardness tester. Small, complex-shaped stampings can be used to test flat surfaces that cannot be measured on an ordinary bench Rockwell hardness tester.
Stamping parts processing includes punching, bending, drawing, forming, finishing and other processes. The stamped parts are mainly made of hot-rolled or cold-rolled (based on cold-rolled) sheet metal materials such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tinplates, stainless steel sheets, copper and copper alloys. Plates, aluminum and aluminum alloy plates.
The PHP series portable surface Rockwell hardness tester is ideal for testing the hardness of these stamped parts. Alloy stampings are the most commonly used parts in metal processing and mechanical manufacturing. Stamping parts processing is a method of separating or forming a metal strip using a mold. Its application is very broad.
The main purpose of hardness testing of stamped parts is to determine whether the degree of annealing of the purchased sheet metal is suitable for stamping parts to be subsequently processed. Different types of stamping parts processing technology require sheets of different hardness levels. The aluminum alloy plate used for stamping parts processing can be tested with the Vickers hardness tester. When the material thickness is greater than 13 mm, the Brinell hardness tester can be used instead. The pure aluminum plate or the low hardness aluminum alloy plate should use the Brinell hardness tester.
In the stamping industry, stamping as described in Chong Hing Hardware Products Co., Ltd. is sometimes referred to as sheet forming, but it is slightly different. The so-called sheet metal forming method refers to a method of forming plastic materials by using a plate material, a thin-walled tube, or a thin profile material as a raw material, and is collectively referred to as sheet material forming. In this case, deformation of the thick plate direction is generally not considered.
