Die is the main process equipment of stamping parts processing manufacturers. 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 the 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 Metal Stamping parts, hydraulic presses are mostly used.
The processing of stamping parts requires the processed material to have higher plasticity and toughness, lower yield ratio and aging sensitivity. Generally, carbon steel elongation δ≥16% and yield ratio σs/σb≤70% are required. 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.
