Description

One-time upturning side belt punching and flanging die

Technical Field

The utility model relates to a disposable turn-ups area dashes turn-ups mould.

Background

A stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping. Stamping is a press working method in which a die mounted on a press machine is used to apply pressure to a material to cause separation or plastic deformation thereof, thereby obtaining a desired part. The punching is a punching process of punching a hole in a material by using a punch, the hole flanging is a punching process of turning the material into a side-standing flange along the periphery of an inner hole, and the flanging is a punching process of turning the material into a side-standing short edge along the periphery of an outline curve.

Aiming at some specific products (such as parts of automobiles), the processing precision is high, the batch size is large, and multi-station processing, such as punching, hole flanging, flanging and other stamping processes, can be frequently used. The existing die basically needs two or three working procedures, so that multiple positioning and multiple stamping can be caused, the processing precision is not high, and the efficiency is low.

As the utility model discloses further improve, the jacking force of ejector pin is greater than the jacking force of nitrogen cylinder.

As the utility model discloses further improve, the top machine-shaping portion of die corresponds with flanging die's interior shaping portion.

As the utility model discloses further improve, the inside processing die feed opening of die.

As the utility model discloses further improve, workstation feed opening under the processing of lower workstation department.

The utility model has the advantages that:

the ejector rod is arranged below the ejector block, the nitrogen cylinder is connected with the flanging male die, and the method for processing the outer forming part and the inner forming part on the lower part of the flanging male die is simple in structure, high in product precision and capable of achieving three-time forming through one-time positioning, and production efficiency is improved.
