Hardness testing of metal stamping parts

Hardness testing of metal Stamping parts

The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex patterns can be used to test the plane is very small, can not be tested on the ordinary desktop Rockwell hardness tester. The PHP series portable surface Rockwell hardness tester is very suitable for testing the hardness of these stamping parts. Changzhou stamping parts processing are very commonly used parts for metal processing and machine production platforms. Metal stamping parts processing is a processing technique that uses molds to separate or form metal strips. Its use limit is very broad.

Stamping processing includes punching, winding, Deep Drawing, forming, finishing and other processes. The material of stamping parts processing is mainly hot-rolled or cold-rolled (mainly cold-rolled) metal plate and strip material, 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.

The die used for stamping parts is called Stamping Die, or die for short. The die is a special object for batch processing of materials (metal or non-metal) into the required stamping parts. Punching dies are critical in stamping. Without a die that meets the requirements, mass stamping production will be difficult; without an excellent die, an excellent stamping process cannot be achieved. The stamping process and die, stamping equipment and stamping materials constitute the three factors of stamping processing. Only when they are connected to each other can stamping parts be obtained.

Compared with other techniques of machine processing and plastic processing, stamping processing has many weird advantages in both technical and economic aspects.

Stamping processing is the production technology that makes the sheet metal in the mold simply receive the deformation force and deform by means of the general rules or the power of the special stamping equipment, so as to obtain the production technology of product parts with inevitable style, size and function. Sheet materials, molds and equipment are the three factors of stamping processing. Stamping is a metal cold deformation processing technique. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the most important techniques of metal plastic processing (or pressure processing), and it also belongs to the material forming engineering technology.

Due to the superiority of stamping, stamping processing has a wide range of applications on various platforms of the people’s economy.

In aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railways, post and telecommunications, transportation, chemicals, medical appliances, household appliances and light industry, there are stamping processes. Not only is it used in all industries, but everyone is in contact with stamping products. There are many large, medium and small stamping parts on airplanes, trains, automobiles, and collapsed planes.

The car body, frame, rim and other parts are all stamped out. According to relevant survey statistics, 80% of bicycles, sewing machines, and watches are stamped parts; 90% of TV sets, tape recorders, and video recorders are stamped parts; there are also food metal cans, steel steam pots, enamel bowls and stainless steel tableware. , They are all stamping products using molds; stamping parts are indispensable even in computer hardware.
