Basic knowledge of metal processing stamping parts
　　
　　Hardware stamping parts are widely used in various fields of our lives, including some electronic devices, auto parts, decorative materials and so on. The stamping parts we usually refer to generally refer to cold stamping parts. For example, if you want to turn an iron plate into a fast food plate, you must first design a set of molds. The working surface of the mold is the shape of the plate. Press the iron plate with a mold and it becomes the plate you want. This is cold stamping, which is to directly stamp the metal material with the mold.
　　
　　-Detection of metal stamping parts:
　　
The hardness test of 　　 pieces adopts Rockwell hardness tester. Small stamping parts with complex shapes can be used to test the surface is very small, can not be tested on the ordinary desktop Rockwell hardness tester.
　　
　　 Stamping parts processing includes punching, bending, deep drawing, forming, finishing and other processes. The materials processed by stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) sheet metal materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy Plate, aluminum and aluminum alloy plate, etc.
　　
　　 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 processing is a processing method that uses molds to separate or shape metal strips. Its application range is very broad.
　　
　　 The main purpose of the hardness test of stamping parts is to determine whether the annealing degree of the purchased metal sheets is suitable for the subsequent stamping parts processing. Different types of stamping parts 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, it can be changed to a Barcol hardness tester. The pure aluminum plate or low hardness aluminum alloy plate should use the Barcol hardness tester.
　　
　　In the stamping industry, stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the forming method that uses sheets, thin-walled tubes, thin profiles, etc. as raw materials for plastic processing, collectively referred to as sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.
