Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a pipe cutting device. Background Art

[0002] Pipe fittings are a general term for parts used for connection, control, direction change, flow diversion, sealing and support in pipeline systems. They can connect pipes into a complete pipeline system and play a key role in the pipeline system. There are many types of pipe fittings. According to different processing techniques, they can be divided into butt-welding pipe fittings (including those with welds and those without welds), socket welding pipe fittings, threaded pipe fittings, flange pipe fittings, etc. In the processing of pipe fittings, it is often necessary to cut the pipe fittings first to facilitate subsequent welding, polishing, grinding and other processes.

[0003] In the prior art, the pipe cutting process is often carried out by a pipe cutting machine. In simple terms, the working process is to manually insert the end of the pipe into the machine tool, and the controller on the machine tool drives the chuck to clamp the pipe through the driver, and then the drive motor of the machine tool drives the pipe to rotate, and finally the pipe is cut by the radially fed cutter to complete the cutting of the pipe; after the pipe is loaded, one end needs to be manually aligned, and the process of axial feeding of the pipe after one cutting needs to be completed manually, so the processing efficiency is low and the labor cost is high, especially for steel pipes with smaller diameters, the number is large and the labor intensity is high, so we propose a pipe cutting device to solve the above problems. Utility Model Content

At the same time, when the electromagnet 9 releases the magnetic force, it is convenient to replace the wave placement plate 11 to match thin steel pipes of different sizes.

[0023] A U-shaped frame 12 is fixedly connected to the top of one of the machine bases 2, and a cylinder 13 is fixedly connected to the top of the U-shaped frame 12.
