Abstract

The invention discloses an U-shaped support punching die. Punching of the top end and two sides of a U-shaped support is completed through the U-shaped support punching die, so that large errors in positions of processed holes are avoided, hole processing accuracy and production efficiency are improved, and the U-shaped support punching die is low in production cost and high in safety.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a U-shaped bracket punching die. Background technique [0002] U-shaped bracket is a commonly used part in automobiles. It is a part used to connect the frame and the body. It plays a role of stability and reinforcement and increases safety protection performance, so the technical requirements are relatively high. [0003] At present, the U-shaped bracket is processed in separate parts, which is welded by several steel plates, and then drilled. With this manufacturing method, the consistency of parts processing is poor, and the dimensional accuracy cannot meet the technical requirements. Even if it is processed, it cannot be matched with the frame and body, the drilling accuracy is not high, the appearance quality is poor, and the production efficiency is low. , the production cost is higher, and the safety is low. Contents of the invention [0004] The purpose of the pre...
