Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a portable magnetic pipe cutting machine. Background Technology

[0002] Magnetic pipe cutting machine is an industrial equipment specifically designed for cutting seamless steel pipes. It is mainly used in the petroleum, chemical, shipbuilding, power generation, and construction and installation industries. This equipment achieves automatic circumferential cutting by adsorbing the surface of the steel pipe with a magnetic wheel. It supports oxy-acetylene or oxy-propane flame processes and is suitable for cutting and beveling seamless steel pipes with a diameter of 108 mm or more and a wall thickness of 5 to 50 mm.

[0003] The existing magnetic pipe cutting machines have fixed magnetic wheels at the bottom, and the distance between the magnetic wheels cannot be adjusted. When cutting pipes of different diameters, the machine chassis may come into contact with the side wall of the steel pipe. In this case, the magnetic pipe cutting machine cannot move normally along the circumference of the pipe, thus reducing its applicability. Utility Model Content

[0028] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the adjustment mechanism includes two limiting seats 11 symmetrically arranged at the bottom of the cutting machine body 1. A first rotating shaft 12 is rotatably connected to the limiting seat 11. A positioning plate 18 is arranged between the first rotating shaft 12 and the second rotating shaft 13. The positioning plate 18 is rotatably connected to the first rotating shaft 12, and the second rotating shaft 13 is rotatably connected to the positioning plate 18. A drive roller 14 is arranged on the first rotating shaft 12, and a driven roller 15 is arranged on the second rotating shaft 13. The drive roller 14 and the driven roller 15 are connected by a first transmission belt 16.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, each of the two first rotating shafts 12 is equipped with a transmission roller 19, which is connected to each other by a second transmission belt 20. A drive motor 31 is provided on the limiting seat 11, and the output end of the drive motor 31 is fixedly connected to the first rotating shaft 12.
