Description

An automatic blanking metal mold

technical field

The utility model relates to a metal mold, in particular to an automatic blanking metal mold.

Background technique

In industrial production, various presses and special tools installed on the press are used to make metal materials into parts or products of the required shape through pressure. Such special tools are collectively called metal molds. Metal molds can be divided into:

(1) Blanking die: The material is separated along the closed or open contour line. Such as blanking die, punching die, cutting die, notch die, trimming die, cutting die, etc.

(2) Bending mold: A mold that bends a sheet blank or other blank along a straight line (bending line) to obtain a workpiece with a certain angle and shape.

(3) Drawing die: It is a mold that makes the sheet blank into an open hollow part, or further changes the shape and size of the hollow part.

(4) Forming mold: It is a mold that directly copies the rough or semi-finished workpiece according to the shape of the convex and concave molds in the figure, and the material itself only produces local plastic deformation. Such as bulging die, shrinking die, expanding die, undulating forming die, flanging die, shaping die, etc.

A considerable part of the metal molds are punching molds. After punching, the waste needs to be manually removed, which is very cumbersome and seriously affects the processing efficiency. At present, some metal molds have a blanking hole in the middle of the punching tool, which can automatically discharge the waste into the leakage groove, save labor, and can effectively control the cost of mold opening, but the processing efficiency is limited, and the waste in the leakage groove needs to be cleaned regularly .
