Multi-shaft drive bending machine and bending method thereof

Abstract

The invention discloses a multi-shaft drive bending machine which comprises a bending system and an integrated feeding and discharging system. The bending system comprises a horizontal bending drive device. A horizontal bending shaft arranged in the horizontal direction is installed on the horizontal bending drive device. A linkage support is installed on the horizontal bending shaft. An up and down bending drive device is further arranged at the upper end of the linkage support. An up and down bending shaft installed in the vertical direction is installed on the up and down bending drive device. A bending cutter support is installed at the shaft end of the up and down bending shaft. An upper bending cutter and a lower bending cutter are installed at the upper end and the lower end of thebending cutter support correspondingly, wherein the upper bending cutter and the lower bending cutter correspond in upper and lower position. According to the multi-shaft drive bending machine, by means of coordinative matching and adjusting of bending drive, the upper bending cutter and the lower bending cutter can reach different positions, a down pressing drive lifting device cooperates to control down pressing fixing and loosening of an upper pressing cutter and feeding and discharging action of feeding and discharging drive, and bending of bent parts in any shape, at any angle and with any flexible radian is completed.

Description

technical field [0001] The invention relates to the field of bending equipment and bending devices, in particular to a multi-axis drive bending machine and a bending method thereof. Background technique [0002] The bending machine in the prior art completes the bending through the linkage of the upper and lower bending knives, but the existing bending machines generally have relatively significant shortcomings: the shape and bending angle formed by the bending machine are limited, and it is not easy to control, can not achieve any required shape and required bending angle; this is mainly reflected in two points, one is the problem of the driving mode, the existing bending machine drive can not realize the multi-axis simultaneous linkage mechanism, so that the bending knife The head can reach any position, which leads to the limitation of its bending shape and bending angle; another point is that the design of the head shape of the bending knife is too conventional, and the ...

[0002] The bending machine in the prior art completes the bending through the linkage of the upper and lower bending knives, but the existing bending machines generally have relatively significant shortcomings: the shape and bending angle formed by the bending machine are limited, and it is not easy to control, can not achieve any required shape and required bending angle; this is mainly reflected in two points, one is the problem of the driving mode, the existing bending machine drive can not realize the multi-axis simultaneous linkage mechanism, so that the bending knife The head can reach any position, which leads to the limitation of its bending shape and bending angle; another point is that the design of the head shape of the bending knife is too conventional, and the shape of the head is fixed after production. One head intelligently bends one The angle is fixed, and the cutting head of the bending knife in the prior art is usually set in a push-down structure, which can only complete the bending corresponding to the shape of the cutting head; Only the machete head can complete the corresponding bending, resulting in a serious reduction in work efficiency

[0003] In addition, the feeding, unloading and positioning in the existing bending machine are usually controlled by humans, which will affect the efficiency, quality and accuracy
