A shearing and bending mechanism

Abstract

The invention discloses a shearing and bending mechanism which comprises an upper die base connected under a press machine and a lower die base connected under the upper die base. A flanging convex die is connected under the upper die base, a lower cavity is formed in the bottom of the flanging convex die, a material pressing block is connected in the lower cavity, an upper cavity is formed in the top of the lower die base, a forming inserted block is connected in the upper cavity, peripheral guide pins are arranged between the material pressing block and the forming inserted block, a product material piece is arranged on the surfaces of the peripheral guide pins, a bending convex die is arranged on one side of the lower cavity of the flanging convex die, an edge cutting convex die is arranged on the other side of the lower cavity of the flanging convex die, the length of the edge cutting convex die extending downwards is longer than that of the bending convex die, a cutting inserted block is arranged on the lower die base and at the position corresponding to the edge cutting convex die, the edge cutting convex die can extrude the product material piece on the peripheral guide pins, and the bending convex die can extrude the product material piece. The shearing and bending mechanism simplifies bending procedures, improves bending automation, saves bending time and daily bending mechanism maintaining time and reduces bending cost.

Description

technical field [0001] The invention relates to the technical field of parts bending processing, in particular to a shearing and bending mechanism. Background technique [0002] Existing parts, especially metal parts, must be cut out of the product shape in the previous step before bending and forming, and then use a punching machine to stamp the cut product blank to obtain bending and forming product. [0003] In this way, bending requires at least two processes, and the forming machines used in each process are different. In a larger factory, each process requires different craftsmen and operators, and each process is waiting for acceptance. The time is also longer, and there is one more process, which increases the difficulty and cost of mold parts processing, and the daily maintenance and debugging of the mold are also more troublesome. Contents of the invention [0004] In order to overcome the deficiencies of the above-mentioned prior art, the present invention pro...
