Novel upper hole flanging die structure for U-shaped stamping part

Abstract

The invention relates to the field of stamping equipment, and particularly discloses a novel upper hole flanging die structure for a U-shaped stamping part, which comprises a female die frame, a hole flanging female die, a male die frame and a hole flanging male die, one side of the male die frame is open, a to-be-machined part can be conveniently placed in the male die frame, and meanwhile structures of other places are adaptively optimized. After the to-be-machined part is placed in place, the to-be-machined part is jointly clamped and properly extruded by the female die frame and the male die frame, then the to-be-machined part is clamped and properly extruded by the hole flanging female die and the hole flanging male die, and each of four movable parts is small in stroke, stable in movement and high in structural practicability; the novel structure is high in applicability, the closing height of the movable parts is small, and the production requirements of more production devices can be met; and the novel structure is high in realizability, a numerical control machining machine is convenient to debug, and part production is stable.

Description

technical field [0001] The invention belongs to the field of stamping equipment, and in particular relates to a novel structure of a hole turning die for a U-shaped stamping part. Background technique [0002] In order to meet some functional requirements of automobile sheet metal parts, the part shape will be designed as U-shaped and the inner edges of the holes on both sides will be turned outward, such as figure 1 shown. The parts adopt the process of forming → shaping → punching → hole turning. The hole turning process is to meet the production characteristics of stable feeding and convenient unloading. The upper turning mold structure is adopted. The parts need two stamping processes of OP40 / OP50, which are processed separately Flip holes up and down. [0003] In the traditional upturning mold structure, after the mold is opened, the spring lifts the support plate up to a height of H, and the parts are placed on the support plate; then the upper and lower molds (also ...

AI Technical Summary

Problems solved by technology

[0004] In general, the traditional upturning die structure cannot meet the stamping production requirements of some parts: the stroke of the supporting plate is high, the stability of the die is poor, there are many restrictions on material selection, the closing height of the die is high, so the requirements for the press are high, and the punch is easy to interfere with this. Parts in the program so that they do not meet the requirements of continuous production
