Abstract

The invention relates to a large angle bending method of an automatic knife bending machine. The method includes the following steps that pre-bending is performed, wherein a bending device bends a to-be-bent knife to a preset bending point so that the knife can be bent to a preset angle; synchronous feeding is performed, wherein the bending device continues to bend the knife, and a feeding devicesynchronously feeds the knife forward to a preset length until the knife is bent. According to the method, the knife is bent to the preset bending point by pre-bending, then the feeding device synchronously feeds the knife forward to a preset length in the subsequent bending process, thus tension is balanced in the subsequent bending process, the accuracy of a bending position is ensured, the influence of the bending tension is eliminated, and thus the effect of tension balance and high precision is achieved.

Description

technical field [0001] The invention relates to the field of knife belt processing, in particular to a large-angle bending method for an automatic machete machine. Background technique [0002] The machete machine is widely used in the production of high-precision knife templates such as electronics and optoelectronics. With the rapid development of the electronics, printing and packaging industries, the computerized automatic machete machine, as one of the two core equipments in the die production, plays a decisive role in the efficiency and precision of the die processing. Such as figure 1 As shown, the automatic curved knife machine needs to go through the steps of feeding, punching, grinding and bending when processing the knife mold. It is necessary to grind different grooves 2' on both sides of the blade to facilitate subsequent bending. [0003] Most of the automatic curved knife machines use the screw to clamp the knife back and forth, the double screw to switch t...
