Metal stamping parts are widely used in various fields of our life, including some electronic devices, auto parts(for example, racing exhaust pipes,stainless steel exhaust racing header,double layer EXhaust Flex Pipe Bellow Flexible Joint Coupler auto accessories exhaust flex pipe), decorative materials and so on. We usually say that stamping parts 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. Pressing the iron plate with the mold will turn it into the plate you want. This is cold stamping, that is, stamping hardware materials directly with the mold.
-Inspection of metal stamping parts:
Rockwell hardness tester shall be used for hardness test of parts. Small stamping parts with complex shapes can be used to test small planes, which can not be tested on ordinary bench Rockwell hardness tester.
Stamping processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plate, alloy steel plate, spring steel plate, galvanized plate, tinplate, 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 the field of metal processing and mechanical manufacturing. Stamping parts processing is a processing method that uses dies to separate or form metal strips. Its application range is very broad.
The main purpose of hardness testing of stamping materials is to determine whether the annealing degree of purchased metal plates is suitable for the subsequent stamping processing. Different types of stamping processing processes require plates with different hardness levels. The aluminum alloy plates used for stamping can be tested with a Vickers hardness tester. When the material thickness is greater than 13mm, a Babbitt hardness tester can be used. Pure aluminum plates or low hardness aluminum alloy plates should use a Babbitt hardness tester.
In the stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called plate forming refers to the forming method of plastic processing with plates, thin-walled tubes, thin sections, etc. as raw materials, which is collectively referred to as plate forming. At this time, the deformation in the direction of thick plates is generally not considered.
