Three elements of stamping

Stamping processing requires the processed material to have higher plasticity and toughness, lower yield ratio and aging sensitivity. Generally, the elongation of carbon steel is required to be δ≥16%, and the yield ratio stamping is a processing method. Mainly plates, strips, pipes and other profiles, the use of stamping equipment through the role of the mold to obtain the required part shape and size.

Stamping is a processing method. The blanks are mainly plates, strips, pipes and other profiles. The stamping equipment is used to obtain the required part shape and size through the function of the mold.

Materials, molds and equipment are the three elements of stamping.

Die is the main process equipment for stamping processing. The surface quality, dimensional tolerances, productivity and economic benefits of stamping parts have a great relationship with the mold structure and its reasonable design. According to the combination of stamping process, it is divided into: single process simple mold, multi-process continuous mold and composite mold.

Stamping equipment mainly includes mechanical presses and hydraulic presses. In mass production, high-speed presses or multi-station automatic presses should be used as much as possible; in small batch production, especially in the production of large thick plate stamping parts, hydraulic presses are often used. The processing of stamping parts requires the processed material to have higher plasticity and toughness, lower yield ratio and aging sensitivity, and generally require carbon steel elongation δ≥16%, yield ratio σs/σb≤70%, low Alloy high-strength steel δ≥14%, σs/σb≤80%. Otherwise, the stamping performance is poor, and certain measures must be taken in the process, thereby increasing the manufacturing cost of the parts
