Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to aviation alloy bar cutting equipment. Background Art

[0002] In the traditional technology, the bar cutting method of aviation materials is usually to complete the cutting and grinding of the bar by manual operation, and then fix the bar, and then the operator cuts and grinds the bar with a handheld cutting machine. This cutting method will cause the labor intensity of the operator to be high, the working efficiency to be low, and the processing accuracy of the manually cut bar to be low. For this reason, automatic bar cutting equipment has appeared in the prior art to reduce the labor intensity of manual labor, improve the working efficiency and cutting accuracy. Since the straightness of the bar itself is not high or the surface is irregular, the existing equipment generally adopts a clamping method at one end to fix it, so that the other end of the bar enters the cutting table for cutting. However, this fixing method leaves the other end of the bar suspended during transportation. When the other end of the bar enters the cutting table, due to the long length of the bar, the other end will sag, so that the other end of the bar hits the part of the cutting table used to support the bar, causing damage to the bar.
