Hardness testing of metal stamping parts

The hardness test of metal stamping parts adopts Rockwell hardness tester. Small stamping parts with complex shapes 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. 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. Stamping 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. The die used for stamping parts is called stamping die, or die for short. The die is a special tool for batch processing of materials (metal or non-metal) into the required stamping parts. Punching dies are very important in stamping. Without a die that meets the requirements, mass stamping production will be difficult; without advanced stamping dies, advanced stamping processes cannot be realized. The stamping process and die, stamping equipment and stamping materials constitute the three elements of stamping processing. Only when they are combined can stamping parts be obtained. Compared with other methods of mechanical processing and plastic processing, stamping processing has many unique advantages in both technical and economic aspects. Stamping processing is the production technology of using the power of conventional or special stamping equipment to directly subject the sheet metal to the deformation force and deform in the mold, so as to obtain product parts with a certain shape, size and performance. Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology. Because of the superiority of stamping, stamping has a wide range of applications in various fields of the national economy. For example, in aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railways, post and telecommunications, transportation, chemicals, medical equipment, household appliances and light industry, there are stamping processes. Not only is it used in the entire industry, but everyone has direct contact with stamping products. There are many large, medium and small stamping parts on airplanes, trains, automobiles, and tractors. 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 cameras are stamped parts; there are also food metal tank shells, steel boilers, enamel bowls and stainless steel tableware. They are all stamping products that use molds; even computer hardware cannot lack stamping parts.
