Process sharing: the selection method of drawing bead shape for metal stamping parts

Today, the author will share with you the selection method of the drawbead shape when forming the metal stamping parts; for everyone to discuss and learn; when the drawn sidewall of the metal stamping part is close to a right angle, the round drawbead is used, and the drawn sidewall is inclined to When the process is supplemented and adjusted, the material is drawn in, because it is close to the bulge forming, so the square rib is mainly used; the drawing depth of stamping parts is low, there is no process supplement or lower, and the drawing threshold needs to be given a reasonable and uniform tension in the early stage ; When the strength of the metal stamping parts is not problematic, the drawing threshold can be used as much as possible to maximize the material utilization. The position of the drawing bead center line is designed according to the above-mentioned basic value, but when there are more waste parts, especially when the corners are formed In order to prevent cracking in the recessed part, it is often necessary to increase the R angle of the die. Therefore, the drawing center line must be moved away from the parting line of the punch in advance. Prevent interference between the draw bars; Dongguan Co., Ltd. was established in 2004 and is located in the Dongguan Provincial Economic Development Zone.
