1 The designed metal stamping parts must meet the product use and technical performance, and be easy to assemble and repair.
2 The designed stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. Use low-cost materials where possible, and make parts as scrap-free and blank as possible.
3 The designed stamping parts must be simple in shape and reasonable in structure, so as to simplify the mold structure and simplify the number of processes, that is, use the least and simplest stamping process to complete the processing of the entire part, reduce the use of other methods for processing, and have Conducive to stamping operations, easy to organize mechanized and automated production, in order to improve labor productivity.
⑷ The designed stamping parts should try to make the dimensional accuracy grade and surface roughness grade as low as possible under the condition of normal use, which is conducive to the exchange of products, reduces waste and ensures stable product quality.
The hardness test of metal stamping parts adopts Rockwell hardness tester. Small, complex-shaped stampings can be used to test small planes that cannot be tested on ordinary benchtop Rockwell hardness testers.
The processing of stamping parts includes blanking, bending, deep drawing, forming, finishing and other processes. The materials for stamping parts are mainly hot-rolled or cold-rolled (mainly cold-rolled) metal sheet and strip materials, such as carbon steel sheets, alloy steel sheets, spring steel sheets, galvanized sheets, tin-plated sheets, stainless steel sheets, copper and copper alloys Plate, aluminum and aluminum alloy plate, etc.
PHP Series Portable Surface Rockwell Hardness Testers are ideal for testing the hardness of these stampings. Alloy stamping parts are the most 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 a metal sheet. Its application range is very broad.
