What are the commonly used precision stamping technologies? 'Hardware'

Netizens ask: What are the commonly used precision stamping technologies? Can you give a brief introduction? Hardware: Nowadays, there are some simple precision stamping processes. As a supplement to precision stamping technology, some shapes are simple and only partially require fine blanking. In factories with small size, small output and no special fine-blanking equipment, promotion and application can also achieve good technical and economic benefits. These precision stamping technologies are as follows: 1. Precision stamping technology for ordinary presses a. Refurbishment-use special refurbishment Also known as trimming die trimming the blanking and punching surface of the blank to obtain a straight, smooth and high-precision punching surface, including: outer edge trimming, inner hole trimming, stacking trimming, vibration trimming, etc. b. Smooth blanking-use special punching dies with special structures such as micro-gap or negative-clearance rounded edges to smoothly blank low-carbon steel and non-ferrous metal blanking parts with high plasticity to obtain smooth and smooth high-precision punching. section. Commonly used smooth blanking processes include: micro-clearance rounded edge smooth blanking, negative clearance smooth blanking, stepped punch fine punching, synchronous cutting and extruding fine blanking, extrusion fine punching, and burr-free blanking, etc. . 2. Precision stamping technology of special fine-blanking machine a. The spirit of strong pressing plate-the use of different structures of strong pressing plate for pressing edge, reverse top and fine blanking (FB), including: has been popularized for production use The fine blanking technology of the V-shaped gear ring strong blank holder and the less used fine blanking method with the serrated pressing plate, the tapered pressing plate, the boss-shaped pressing plate...etc. b. Fine blanking of opposite dies-using the principle of plane cutting, the upper and lower corresponding pairs of punches and dies are used for punching according to the specified degree. It was invented by the Japanese in 1968 and has been promoted for production in Japan. Fine blanking technology. It is also used in our country but has not been popularized. c. Double movement and reciprocating fine blanking-not promoted and applied. In the production of various electromechanical and home appliance stamping parts on site, the actual needs and the number of blanking parts that can be integrated fine blanking are limited. Moreover, a considerable part of the punching parts only need local fine blanking, especially if only a small part of the group hole and group slot hole is fine punched, it is more economical to apply ordinary press fine blanking technology; for only local fine blanking to obtain high-precision hole shape The inner shape or part of the outer shape of the blanking parts with a distance between the holes, no burrs and a smooth and smooth cutting surface can be smoothly punched to meet the requirements. The above is the supplementary explanation about the commonly used precision stamping technology. I hope it will be helpful to you. If you want to know more, please consult:
