1. The scope of application of metal stamping parts:

1. Special stamping enterprises. For example, the stamping of aviation parts belongs to this type of enterprise, but these craft factories are also classified into some large factories.

2. Stamping of parts and components in automobile and other industries. Mainly punching and shearing. Many enterprises in this sector belong to the standard parts factory, and there are also some independent stamping factories. At present, there are many such small factories near some automobile factories or tractor factories.

3. Daily necessities stamping factory. Some handicrafts, tableware, etc. These factories have also developed greatly in recent years.

4. Stamping in the automotive industry. Mainly deep drawing. In my country, this part is mainly concentrated in large factories such as automobile factories, tractor factories, and aircraft factories, and independent large-scale stamping and deep drawing factories are rare.

5. Electric parts stamping factory. This type of factory is a new industry, developed with the development of electrical appliances, and these factories are mainly concentrated in the south.

6. Household appliance parts stamping factory. These factories only appeared after the development of home appliances in our country, and most of them are distributed in home appliance enterprises.

Second, the detection of metal stamping parts:

The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stampings with complex shapes can be used to test the surface is too small to be detected on ordinary benchtop Rockwell hardness testers. Stamping processing includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts processing are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strip materials, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tin-plated plates, stainless steel plates, copper and copper alloys plate, aluminum and aluminum alloy plate, etc.

The PHP series portable superficial Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Alloy stamping parts are commonly used parts in the fields of metal processing and machinery manufacturing. Stamping processing is a processing method that uses a mold to separate or form metal strips. Its application range is very wide.

The main purpose of the hardness testing of automotive stamping parts is to determine whether the annealing degree of the purchased metal sheet is suitable for the subsequent stamping processing. Different types of stamping processing technology require sheets of different hardness levels. The aluminum alloy plate used for stamping processing can be tested with a Webster hardness tester. When the material thickness is greater than 13mm, a Barcol hardness tester can be used instead. A pure aluminum plate or a low-hardness aluminum alloy plate should use a Barcol hardness tester.

In the stamping parts industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet forming refers to the use of sheets, thin-walled tubes, thin profiles, etc. as raw materials. The forming methods of plastic processing are collectively referred to as plate forming. At this time, the deformation in the direction of the thick plate is generally not considered.
