Rotary angle-wrapping forming stamping die

Abstract

The invention provides a rotary angle-wrapping forming stamping die. The rotary angle-wrapping forming stamping die can solve the problems that according to the prior art, an oil cylinder lateral thrusting forming mechanism is used for forming, the control difficulty is large, production efficiency is low, and the structure is complex. The rotary angle-wrapping stamping die comprises an upper die base, a lower die base and an angle-wrapping forming mechanism. The angle-wrapping forming mechanism comprises a lateral thrusting assembly and a rotary angle-wrapping forming assembly; the lateral thrusting assembly comprises a push rod, a push rod limiting block, a sliding block base, a pressure plate and a sliding block base elastic reset component. The rotary angle-wrapping forming assembly comprises a rotatable swinging block and an ejector block and the swinging block is of a forming structure. The ejector block is fixedly arranged on the lower die base and the side face, facing the side face of the swinging block, of the ejector block is a guiding slope. According to the rotary angle-wrapping forming stamping die, rotary angle-wrapping forming operation is in linkage with die closing operation, the forming cycle is shortened, and the production efficiency is greatly improved; the problem that due to the fact that the rotary angle-wrapping forming operation and the die closing operation are independent, if signal transmission and execution of the rotary angle-wrapping forming operation and the die closing operation are false, an angle-wrapping forming punch is prone to breakage is solved, and the maintenance cost of the die is reduced.

Description

technical field

[0001] The invention relates to a stamping die, in particular to the improvement of the structure of the stamping die used for corner wrapping of stamping products. Background technique

[0002] Appearance products, such as refrigerator door shells, washing machine shells, etc., have very strict appearance and size requirements. In order to achieve good appearance and precise size requirements, a set of molds are usually used for straight edge bending and corner forming. Avoid factors that affect product appearance and size such as cumulative errors caused by replacing different molds.

[0003] In the prior art, corner wrapping is formed by an oil cylinder side pushing molding mechanism arranged in the mold, the product 1 is placed on the lower template 2.1 of the lower mold base 2, and an oil cylinder 3 is arranged at its corner wrapping position, and the oil cylinder 3 is installed On the lower mold base 2, the angle-wrapping punch 4 is driven by the oil c...
