Apa itu setem logam

Rockwell hardness tester digunakan untuk ujian kekerasan stamping logam . Bahagian kecil yang dicop dengan bentuk yang kompleks dapat digunakan untuk menguji pesawat kecil dan tidak dapat diuji pada penguji kekerasan Rockwell desktop biasa. Penguji kekerasan Rockwell permukaan mudah alih siri PHP sangat sesuai untuk menguji kekerasan setem ini. Setem aloi adalah bahagian yang paling biasa digunakan dalam pemprosesan logam dan pembuatan mesin. Pemprosesan bahagian stamping adalah kaedah pemprosesan yang menggunakan die untuk memisahkan atau membentuk jalur logam. Julat aplikasinya sangat luas.

metal Stamping parts processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tinned plates, stainless steel plates, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc.

1. Hardness testing of stamping parts

The main purpose of hardness testing of stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping part processing. Different types of stamping part 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 thickness of the material is greater than 13mm, the Barcol hardness tester can be used. The pure aluminum plate or the low hardness aluminum alloy plate should use the Barcol hardness tester.

2. Hardness testing of stamping parts mold

The main material of the stamping die is die steel (including tool steel and high-speed steel), and sometimes carbide is used.

Stamping parts molds usually require high hardness and wear resistance, heat treatment is essential.
