Rockwell hardness tester is used to test the hardness of metal stamping parts. It can be tested with small-sized stamping parts with complex shapes, and the plane is too small to be tested on the common table Rockwell hardness tester.
Stamping includes blanking, bending, stretching, forming, finishing and other processes. Stamping materials are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal strips, such as carbon steel plates, alloy steel plates, spring steel plates, galvanized plates, tinned plates, stainless steel plates, copper and copper alloy plates, aluminum and aluminum alloy plates, 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 fields of metal processing and mechanical manufacturing. Stamping is a processing method of separating or forming metal strip by using die. It has a wide range of applications.
Extended data
The main purpose of hardness testing of stamping parts materials is to determine whether the annealing degree of purchased sheet metal is suitable for subsequent stamping parts processing. Different kinds of stamping parts require different hardness grades of plates. The aluminum alloy plate used for stamping parts processing can be tested by Wechsler hardness tester. When the material thickness is greater than 13mm, it can be replaced by Buckley hardness tester, and the pure aluminum plate or low-hardness aluminum alloy plate should be tested by Buckley hardness tester.
In the stamping industry, stamping is sometimes called sheet metal forming, but it is slightly different. The so-called sheet metal forming refers to the forming method of plastic processing with sheet metal, thin-walled tube and thin profile as raw materials, which is collectively called sheet metal forming. At this time, the deformation in the direction of thick plate is generally not considered.
Design principle:
(1) designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
⑵ The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the varieties and specifications of materials and reducing the consumption of materials as much as possible. If possible, use low-priced materials, so as not to waste stamping parts as much as possible.
(3) The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the die structure and the number of processes, that is, the whole part is processed with the least and simplest stamping process, and the use of other methods is reduced, which is beneficial to stamping operation, organization and realization of mechanized and automated production, thus improving labor productivity.
