Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a high-precision bar cutting machine. Background Art

[0002] In the field of mechanical processing, bar shearing technology is often used, which is to use a cutting machine to cut long bars into short bars. Bar cutting machine is one of the most common cutting tools, which is widely used in cutting steel bars, idle steel pipes, pipelines, and hangers.

[0003] A traditional cutting machine includes a base and a cutting mechanism hingedly connected to the base, wherein the cutting mechanism is mainly composed of a driving motor and a cutting blade. During use, the bar to be cut is placed between the cutting blade and the base and the bar is fixed before being cut. For example, a bar cutting machine that is easy to clamp and fix is ​​disclosed (announcement) No. CN210025491U. The bar can be clamped and fixed to prevent the unclamped section from bouncing and causing harm to the operator at the moment of cutting, thereby improving the safety performance of the cutting machine. However, the cutting machine still has the problem that when the length of the metal bar or pipe is long, the cutting wheel may cause the bar to shift when it contacts the bar, thereby affecting the cutting accuracy. At the same time, since most of these small cutting machines use the method of manually pressing the cutting head to press down to achieve cutting work, there is still a problem of sparks flying and safety hazards.
