The processing of stamped parts requires that the processed materials have higher plasticity and toughness, lower yield ratio and aging sensitivity, 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 forming performance is poor, and certain measures must be taken in the processing of the metal stamping parts processing plant, thereby increasing the manufacturing cost of the parts.
The mold is the main process equipment for stamping. The surface quality, dimensional tolerances, productivity, and economic benefits of stamping parts have a great deal to do with the mold structure and its rational design. According to the combination of stamping processes, there are: single mode simple mode, multiple process continuous mode and multiple mode.
Stamping equipment mainly includes mechanical presses and hydraulic presses. In high-volume production of metal stamping parts processing plants, high-speed presses or multi-station automatic presses should be used as far as possible; in the production of small batches, especially in the production of large-sized slab stamping parts, hydraulic presses are often used.
Stamping parts processing, the blanks are mainly plate, strip, pipe and other profiles, the use of stamping equipment through the role of the mold, so that they get the required part shape and size. Materials, molds and equipment are the three elements of stamping
