Materials, moulds and equipment are the three elements of stamping.
Stamping parts are required to be processed with high plasticity and toughness, lower bending strength ratio and aging sensitivity. It is generally required that the elongation of carbon steel to be [delta] 16% or flexion ratio is a processing method, and its blank is mainly plate, strip, pipe and other sections. The shape and size of the parts required.
The stamping process requires high plasticity and toughness, lower flexion strength ratio and aging sensitivity. Generally, the elongation of carbon steel is equal to 16%, the ratio of flexion to strength ratio s/ sigma B < 70%, low alloy high strength steel [delta] 14%, sigma s/ B < B < 80%., otherwise, the stamping forming performance is poor, and some measures must be taken to improve the zero. The manufacturing cost of the piece.
The surface quality, dimensional tolerance, productivity and economic benefits of the stamping parts have a great relationship with the mold structure and its reasonable design. According to the combination of stamping process, it can be divided into simple die, multi process continuous die and compound die.
