Blanking and bending compound die

Abstract

The invention discloses a blanking and bending compound die. The blanking and bending compound diecomprises an upper die set, a female die (7), a material pressing plate (11) and a material ejecting block (8), wherein the upper die set comprises an upper die base (2), an outer male die (5), a left male die (10) and a right male die (14), wherein the outer male die (5) is movably arranged in the upper die base (2) through a guide sleeve (13), a limiting cap A (4) is fixedly arranged at the upper end of the outer male die (5), an elastic body A (3) is arranged between the limiting cap A (4) and the upper die base (2), the material pressing plate (11) is movably arranged in the upper die base (2), an elastic body B (12) is arranged between the material pressing plate (11) and the upper die base (2), a narrow-opening hole cavity is formed in the middle of the female die (7), a blind hole (9) is formed in the bottom of the narrow-opening hole cavity, and an elastic body C (16) is arranged between the lower end of the material ejecting block (8) and the bottom of the blind hole (9). The blanking and bending compound die has the advantages of being high in production efficiency, long in service life and low in production cost.

Description

technical field [0001] The invention relates to a bending composite mold, in particular to a blanking bending composite mold. Background technique [0002] The composite mold can complete multiple processes such as blanking and punching in one stroke of the punching machine. It is an efficient and economical stamping processing mold. Therefore, it is necessary to develop new composite molds as much as possible and improve the utilization rate of the composite mold. It is an important way to reduce the processing cost of cold stamping process and improve production efficiency. [0003] At present, the U-shaped bending structure of the flanging usually requires two forming processes: the first U-shaped forming, and the second flanging forming. The prior art also discloses a lot of U-shaped bending composite molds for one-time forming of flanging, but these composite molds do not have a blanking process, so the production efficiency is reduced and the production cost is increa...

Problems solved by technology

The prior art also discloses a lot of U-shaped bending composite molds for one-time forming of flanging, but these composite molds do not have a blanking process, so the production efficiency is reduced and the production cost is increased. Further improvement is required to provide a more structurally A simple mold realizes one-time forming of blanking and flanging U-shaped bending
