Steel pipe cutting is not only related to the utilization rate of materials, but also affects the quality and production efficiency of the final product. Therefore, it is crucial to choose the right cutting method and equipment. There are various methods for steel pipe cutting, mainly including manual cutting, mechanical cutting, flame cutting, plasma cutting, etc. The most commonly used method is mechanical cutting, which uses special mechanical equipment for cutting, such as steel pipe cutting machines, band saws, etc. Mechanical cutting has high efficiency and high precision, and is suitable for batch cutting and large steel pipe cutting.

[0006] With such arrangement, when in use, first place the steel pipe in the loading trough of the loading area, and put the other end into the unloading trough of the unloading area, then use the clamping tool to stabilize the steel pipe, then control the first telescopic machine to press down the cutting disc to cut the steel pipe, after cutting, the first telescopic machine will raise the cutting disc, and at the same time, the third telescopic machine will push the sliding plate away from the loading area, and take the half steel pipe in the unloading trough away from the top of the edge grinding assembly, and then the second telescopic machine will push the edge grinding frame to rise, so that the edge grinding assembly on the edge grinding frame moves to The center position of the two sections of steel pipes, and then the fourth telescopic machine controls to push the clamping plate, the clamping plate will push the half steel pipes on both sides to move them toward the edging assembly and clamp them on the edging assembly. Finally, the edging motor runs to make the edging assembly rotate at high speed to grind the cutting surface. After grinding, each telescopic machine controls its corresponding parts to return to the original position, and then the next cutting and grinding can be carried out without removing them for grinding separately, which is more convenient. Each telescopic machine can use a motor, cylinder or hydraulic cylinder according to needs.

[0007] Furthermore, the edge grinding mechanism also includes a rotating wheel and a synchronous belt. The two edge grinding components are respectively arranged at both ends of the rotating wheel. The synchronous belt is sleeved on the edge grinding motor and the rotating wheel. A U-shaped frame is provided on the top of the edge grinding frame, and the rotating wheel is provided with a rotating shaft passing through the two side plates of the U-shaped frame.

[0008] With this arrangement, the edge grinding motor and the edge grinding assembly can be staggered, reducing the axial distance of the edge grinding mechanism, avoiding excessive spacing between the loading area and the unloading area, making the structure more stable, and adopting synchronous belt linkage, which has strong stability.
