What are the advantages of multiple drawing and one-time stretch forming for stretch parts? Metal stamping plant
Forming and stamping of drawing parts is one of the six precision technologies of Heju. The technical features are as follows: the drawing tolerance can reach ± 0.015mm, the appearance is free of defects, and the R / T is less than 1.0. Tensile parts are used in mechanical, electronic, electrical, instrument, automobile, aviation and military products.
In the drawing forming process of drawing parts, there are one drawing forming and several drawing forming. One time drawing is characterized by one-time forming, which can improve the production efficiency, but the disadvantage is that the one-time forming is easy to be not in place, and the change degree of each drawing is required and cannot be changed too much.
Multiple drawing can improve the qualified rate of products, and it is not easy to produce waste products. Multiple drawing can ensure the accuracy of the workpiece, elongation coefficient and production efficiency are greatly improved. Multiple drawing can be more symmetrical and reduce the defect rate of the workpiece.
The advantages and disadvantages of one-time drawing and multiple drawing can be selected according to the characteristics of products when stamping precision drawing parts.
