Description

An Angle Adjusting Mechanism of a Shearing Die

technical field

The invention relates to the technical field of shearing dies, in particular to an angle adjustment mechanism of a shearing die.

Background technique

In the process of production and processing, strip materials are very common. The strip material usually needs to be cut into the required length, and then proceed to the subsequent production process, and finally form the product. Due to the large batch size, the cutting efficiency of conventional lathes is too low. Therefore, the tooling used on reciprocating equipment such as punching machines was invented. The reciprocating motion of the equipment is used to generate torque, which collides with the moving blade of the shearing tooling, and the material is reserved from the center of the fixed blade. After the material hole passes, the material is cut off by the shear force to achieve the required purpose.

The existing punch shearing dies mainly have the following problems: first, the mold structure is complex, and it needs to be used in one set or multiple sets to realize cyclic operation; second, the work efficiency is low, and it usually cannot meet the needs of mass production; The changeability is poor, which is contrary to the current processing and production needs. Many of the above problems have seriously affected the production demand of the punch shearing process. Among them, the most prominent problem is the problem of versatility. The existing shearing dies can only process regular workpieces, but they cannot handle the shearing of 0° to 15° trapezoidal plates well.
