Description

Technical Field

[0001] This invention relates to the field of metal pipe processing technology, specifically to a cutting machine tool applied to metal pipes. Background Technology

[0002] Metal pipe fittings are indispensable connection and control components in piping systems. They can connect and extend pipelines, change flow direction, control fluids, and compensate for deformation. The processing of metal pipe fittings requires processes such as cutting, stamping, bending, heat treatment, and surface treatment. Among these, cutting machine tools are common processing equipment that can precisely cut pipe fittings through methods such as plasma cutting. There are a wide variety of cutting machine tools available on the market for metal pipe fittings.

[0003] For example, Chinese patent CN117532377B relates to the field of metal processing technology and discloses a cutting machine tool for metal pipes, including a machine tool base, a ventilation plate installed on the outer wall of the machine tool base, a machine tool operating table installed on the top of the machine tool base, and a waste chip collection box slidably connected to the inner wall of the machine tool base. This cutting machine tool for metal pipes can transmit signals through the control panel to make the disc rotate under the drive of the motor. At the same time, the electric telescopic cylinder drives different cutting tools to move up and down, so that the cutting tools can move up and down repeatedly on the inner wall of the clamping column. Due to the cooperation of the lateral sliding component and the limiting component, the cutting tools can move laterally and vertically, so that the appropriate cutting tool can cut the clamped metal pipe without the need to repeatedly change the cutting tools, which increases convenience and improves the cutting efficiency of the device for metal pipes.

[0004] For example, Chinese Patent No. CN220680053U relates to the field of metal processing technology and discloses a high-efficiency metal cutting machine tool, including a machine tool base, a left limiting frame, a limiting arc plate, and a cutting part support. The surface of the machine tool base is provided with a left moving slide groove, and a right moving slide groove is provided on the right side of the left moving slide groove. A cutting part slide groove is provided in the middle of the machine tool base. The left limiting frame is movably installed inside the left moving slide groove. A locking hole is provided inside the left limiting frame, and a limiting arc plate is movably installed inside the locking hole. By installing the machine tool base, left moving slide groove, left limiting frame, limiting arc plate, drive motor, right limiting frame, and other devices, the machine tool achieves a fast and convenient fixing capability, enabling it to quickly fix metal tubes. It also has the ability to adjust the spacing of the clamping parts according to the length of the metal tube, facilitate the adjustment of the cutting position, and has a high-efficiency working capability.

[0005] However, current machine tools used for cutting metal pipes are inconvenient to clamp the left and right ends of the pipes separately during actual use. The pipes are not stable enough and are prone to loosening and shaking. During cutting, the shaking caused by the machining process can easily lead to the pipes being skewed and deformed, affecting the quality of the pipes. Therefore, we propose a machine tool for cutting metal pipes to solve the problems mentioned above. Summary of the Invention
