Main stamping parts

Stamping parts are mainly made of metal or non-metallic sheet materials by means of the pressure of a press machine and formed by stamping die. It mainly has the following characteristics: 　　

(1) Stamping parts are manufactured by stamping under the premise of low material consumption. The parts are light in weight, rigid, and

And after the sheet metal is plastically deformed, the internal structure of the metal is improved, which increases the strength of the stamping parts.　　

(2) The stamping parts have high dimensional accuracy, the same size as the mold parts, and good interchangeability. No further machining is required to meet general assembly and use requirements.　

　(3) During the stamping process, since the surface of the material is not damaged, the stamping parts have a good surface quality and a smooth and beautiful appearance, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments .

Edit the principles of the design of this paragraph (Guide: Reasons for the production of waste stamping parts)

(1) The designed stamping parts must meet the product use and technical performance, and be easy to assemble and repair.

　　(2) The stamping parts designed must be conducive to improving the utilization rate of metal materials, reducing material varieties and specifications, and reducing material consumption as much as possible. Use low-cost materials where permitted, and make the parts as waste-free and waste-less as possible.　

　(3) The stamping parts designed must be simple in shape and reasonable in structure, in order 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, and reduce the use of other methods. And it is conducive to the stamping operation, easy to organize the realization of mechanized and automated production, to improve labor productivity.　　

(4) The designed stamping parts, under the condition of ensuring normal use, try to make the dimensional accuracy level and surface roughness level lower, and it is conducive to product interchange, reducing waste and ensuring stable product quality.

　 (5) The stamping parts designed should be conducive to the use of existing equipment, process equipment and process flow as much as possible to process them, and is conducive to the extension of the service life of the die.
