Description

Technical Field

[0001] The utility model relates to the field of pipe cutting machines, in particular to a pipe cutting machine. Background Art

[0002] Pipe cutting machines are mechanical equipment that are widely used in industries such as petroleum, chemical industry, electric power, natural gas, metallurgy, shipbuilding, boiler, pharmaceutical, water treatment, as well as metal pipe installation projects and metal pipe maintenance in new projects. They have a wide range of uses and can perform cutting and beveling at the same time. The incisions are not deformed, have no burrs, are clean, and have good surface quality.

[0003] The prior art patent number CN211162148U discloses a metal pipe cutting machine, comprising a base and a cutting barrel fixedly arranged on the base, the cutting barrel being a circular tube, and the inner diameter of the cutting barrel being larger, the cutting barrel also being provided with an arc-shaped slot, a cutting knife being provided just above the slot, and the outer diameter of the cutting knife being much larger than the outer diameter of the cutting barrel, the cutting knife being installed in a mounting cover, a motor box being fixedly installed on one side of the mounting cover, and a transmission rod of an output end of a motor in the motor box being transmission-connected. The utility model provides a tubular cutting barrel on the base, and the cutting barrel is provided with an arc-shaped slot for the cutting knife to be pressed into. When the metal pipe is inserted into the cutting barrel and the rotating cutter is used to cut it, the debris generated during the cutting process can be shielded by the shielding effect of the circular tubular cutting barrel, thereby avoiding the situation where the debris splashes, thereby greatly improving the quality of the working environment, having a simple structure and being more practical.

[0035] Hold the handle 502 and press down the rotating rod 501, so that the rotating cutting blade 607 gradually cuts the pipe. During the cutting process, the rotating rod 501 will vibrate. At this time, the connecting block 504 squeezes the spring 507. The spring 507 and its own damper work together to slow down the vibration of the rotating rod 501, making the cutting more stable and safe.

[0036] The electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that controls a computer, etc. The specific implementation method of this disclosure omits the detailed description of known functions and known components.
