Problems solved by technology

[0002] Generally, U-shaped bracket parts can only be completed by punching and blanking first, then bending or bending first, and then punching and blanking. This process requires more equipment and labor, and consumes a lot of energy. Due to the variety of processes, Each process has a certain error, so the cumulative error of the product is relatively large, and if punching and blanking are performed first and then bent, human resources will be increased, production time will be increased, and work efficiency will be reduced

Abstract

The invention discloses a U-shaped support punching blanking bending composite die. Blanking, bending and punching of a U-shaped support are completed through one die, production efficiency is high, used process devices are few, economic benefit is high, and the problem that an existing U-shaped support needs a blanking die, a bending die and a punching die and low production efficiency, large process device number and low economic benefit are caused is solved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a U-shaped bracket punching, blanking and bending composite mold. Background technique [0002] Generally, U-shaped bracket parts can only be completed by punching and blanking first, then bending or bending first, and then punching and blanking. This process requires more equipment and labor, and consumes a lot of energy. Due to the variety of processes, Each process has a certain error, so the cumulative error of the product is relatively large, and if punching and blanking are performed first and then bent, human resources will be increased, production time will be increased, and work efficiency will be reduced. Contents of the invention [0003] The purpose of the present invention is to provide a U-shaped support punching, blanking and bending composite mold, which can complete the punching, blanking and bending of the U-shaped support at one time, thereby ensuring the...
