Description

[0002] In the process of parts processing, it is often necessary to cut a metal round bar into several sections and then process them. The metal round bar cutting machine is a commonly used processing equipment for metal round bars.

[0003] However, the existing metal round bar cutting machines mainly use hydraulic feeding and manual feeding, and their function is to feed the bar to be cut by hydraulic drive or manual feeding, and after the feeding and length setting are completed, the bar is sent to the cutting feed device for cutting. This feeding device has the disadvantages of relatively low feeding accuracy, low automation, low efficiency and high labor cost.

[0004] At the same time, in the prior art, during the cutting process of metal round bars, since the bar clamping mechanism is fixed, a certain displacement is easily generated when the bar is clamped, resulting in inaccurate knife position during cutting, burrs and scratches will appear on the cut surface of the metal round bar, which is not conducive to the processing of the next step.

[0005] To this end, we propose a bar cutting machine to solve the problems existing in the existing technology, improve its work efficiency, save time and effort, and reduce the company's production labor cost; at the same time, a beveling mechanism is set at the bar clamping tooling to improve the clamping stability when clamping the bar, ensuring that the bar will not be displaced during feeding, thereby avoiding burrs and scratches on the cut surface of the metal round bar.
