What kind of hardness tester should be used for different metal stamping parts materials
Stamping parts processing plants, processing metal stamping parts, stainless steel stamping parts, various mechanical parts, with the development of society, stamping products have been applied to various fields, and the materials used in metal stamping parts are also divided into many types, making metal stamping parts, We need to understand the characteristics of the product and the performance of the material. Among them, we also need to test the hardness of the metal stamping parts. The main purpose is to determine whether the purchased metal sheet annealing is suitable for stamping processing; different types of metal stamping Parts processing technology requires plates of different hardness levels. The hardness test of each kind of plate has a prescribed hardness tester to measure, let’s look at it below; 1. Hot-rolled steel plates are usually thicker, and it is generally specified that Brinell hardness testers are used to test the hardness, and Rockwell hardness testers are also used to test hot-rolled steel plates. Yes; you can use the hrb scale, when the portable Rockwell hardness tester is used to test the hot-rolled steel plate, the test can be carried out without sampling, and the operation is very simple; 2. The cold-rolled steel plate used for processing metal stamping parts mainly adopts Rockwell Hardness tester is used to detect hardness, usually hrb scale, for harder ones, hrc scale; 3. Webster hardness tester can be used for material of thin plate, or hrn or hrt scale of surface Rockwell hardness tester can be used; 4. For metal stamping parts The hardness of the processed brass plate can be tested with the hrb scale of the Rockwell hardness tester; the hrf scale can be used for the softer brass plate and red copper plate; 5. The aluminum alloy plate used for processing metal stamping parts can be tested with the Webster hardness tester In testing, the Barcol hardness tester can be used when the material thickness is 13mm. The pure aluminum plate or low-hardness aluminum alloy plate should use the bus hardness tester; the main material of the stamping die is die steel, and sometimes hard alloy and stamping die are used. Usually require high hardness and wear resistance, among which heat treatment is essential. The hardness test of die steel uses Rockwell hardness tester to test the hrc hardness value. When the mold is large and inconvenient to move, the Leeb hardness tester can be used. In order to improve the surface hardness and wear resistance, many metal stamping parts molds and mold parts must undergo surface heat treatment, such as surface nitriding, etc. The article recommends: What are the characteristics of the change in the bending deformation area of u200bu200bthe stamping parts?
