What are the methods of hardness testing of metal stamping parts?
First, the method of hardness testing of metal stamping parts
The hardness test of metal metal stamping parts adopts Rockwell hardness tester. Small stampings with complex shapes can be used for small test surfaces, which cannot be tested on ordinary benchtop Rockwell hardness testers.
The processing of metal stamping parts includes blanking, bending, deep drawing, forming, finishing and other processes. The processing materials of metal stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheets and strips, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper. Alloy plate, aluminum and aluminum alloy plate, etc.
The PHP Series Portable Surface Rockwell Hardness Testers are ideal for testing the hardness of these stampings. Alloy stampings are the most commonly used parts in the fields of metal processing and machine manufacturing. Stamping is a processing method that uses a die to separate or form a sheet metal strip. Its application range is very wide.
The main purpose of the stamping material hardness test is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. The same type of stamping process requires sheets of different hardness levels. Aluminum alloy plates used for stamping parts can be tested with Webster hardness tester. When the thickness of the material is greater than 13mm, it can be replaced by a barcol hardness tester, and a barcol hardness tester should be used for pure aluminum plates or low-hardness aluminum alloy plates.
In the stamping industry, stamping is sometimes also called sheet forming, but it is slightly different. The so-called plate forming refers to a forming method in which a plate, a thin-walled tube, a thin profile, etc. are used as raw materials for plastic processing. At this time, the preparation of the thick plate direction is generally not considered.
Well, the above is the relevant content about the hardness testing method of metal stamping parts, I hope the above content can help readers.
