Quality inspection of automobile die processing

Date of release:2018-07-06 Author: Click:

More and more automobile dies are used in our life. Hardness testing of automobile dies is made by Rockwell hardness tester. Small, complex shape stamping parts can be used to test the plane very small, and can not be detected on the ordinary desktop Rockwell hardness tester. 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 process is the processing method of separating or forming metal strip with mould. Its application range is very wide.


Stamping process includes blanking, bending, drawing, forming, finishing and other processes. The main materials for stamping parts are hot rolling or cold rolling (cold rolling), such as carbon steel, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate.


Hardness testing of 1. stamping parts


The main purpose of the hardness testing of the stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the stamping parts to be processed later. The different kinds of stamping process processes require different hardness levels of the sheet. The aluminum alloy plate used in stamping parts can be tested by the Wechsler hardness tester. When the thickness of the material is more than 13mm, it can be changed to the psteometer. The pure aluminum plate or the low hardness aluminum alloy plate should be made of the pasteurometer.


2, hardness test of stamping die


The main material of stamping die is die steel (including tool steel and high speed steel), and sometimes also uses cemented carbide.


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