Double-action double-angle lateral shaping mechanism

Abstract

The invention relates to a double-action double-angle lateral shaping mechanism which comprises a drive part and a movable male die working part. The drive part is an upper die of a punching device. The upper die is provided with a drive face, an insertion type guide plate is disposed at the front end of the drive face, a vertical face is disposed on the rear side of the upper die, and a mounting face and a mounting guide plate are disposed on the vertical face. When an upper die lateral shaping insert completes work, two upper die wedge drive blocks mounted on the upper die lateral shaping insert starts to work at two different angles. Advance and retreat sequence of wedges is important, the upper die lateral shaping insert starts to work when a movable male die slider and a lower die auxiliary pressing plate are in place, and when the upper die lateral shaping insert completes work, the upper die wedge drive blocks mounted on the upper die lateral shaping insert starts to work. Wedges of different angles are mounted on the wedges, and two working directions are provided. The movable die working part comprises various drive blocks, a nitrogen cylinder, a pressing plate, a balance cushion block, an insertion type guide plate and a wear-resistant plate.

Description

Technical field: [0001] The invention relates to a cold stamping die for an inner and outer cover part of an automobile, in particular to a double-action double-angle side shaping mechanism. Background technique: [0002] With the development of the automobile industry and the maturity of the stamping process, the profile of many stamping parts is very complex, and some concave profiles on the flange surface with negative angles are difficult to realize in the existing structure. Especially when the specific production line cannot be satisfied, because the number of stamping machine tools is not enough, it is urgently hoped that a technology can meet the customer's production line and not increase the number of molds on the basis of no stamping process, but products with negative angle flanging A part with a concave surface on the surface. [0003] The applicant has already applied for a patent application number: 201110241023.8, the subject of which is "a double-movable ...
