Double-action double-angle side shaping mechanism

Abstract

The invention relates to a double-action double-angle side shaping mechanism. It includes a driving part and a working part of the movable punch; the driving part is an upper mold of the stamping equipment, the upper mold is provided with a driving surface, the front end of the driving surface is provided with a plug-in guide plate, and the rear side is a vertical surface on which a mounting surface is provided to install the guide plate; After the work of the upper mold side integral insert is completed, the upper mold wedge drive block installed on the upper mold side integral insert starts to work, and the two upper mold wedge drive blocks work at two different angles; the wedge advances and retreats first and then The relationship is very important. After the sliding block of the movable punch and the auxiliary pressing plate of the lower die are in place, the upper mold side integral insert starts to work, and the upper mold side integral insert is installed on the upper mold side integral insert after the work is completed. The drive block of the mold wedge starts to work; install different angles on the wedge, and the working direction is two; the working part of the movable punch includes: various drive blocks, nitrogen cylinder, pressure plate, balance pad, plug-in guide plate, resistant grinding 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 si...
