[0002] Metalworking, also known as metalworking, refers to the production activities of humans processing materials with metallic properties that are composed of metal elements or mainly composed of metal elements. It is a process technology that processes metal materials into objects, parts, and components, including large parts of bridges and ships, as well as tiny components of engines, jewelry, and watches. It is widely used in different fields such as science, industry, art, and handicrafts. For example, during the production and processing of fitness equipment, specific processing equipment is required to process metal raw materials into fitness equipment parts.

[0003] In the prior art, when processing metal cylindrical or tubular raw materials in fitness equipment, they often need to be cut to a predetermined length. When traditional cutting devices process metal pipes, the cut end faces will produce burrs of varying degrees due to different friction and cutting amounts. When the cutting amount is large, the burrs generated by the cutting of the metal pipes will also be larger. At this time, the burrs on the cut end faces of the metal pipes may not be easy to completely remove by grinding or the like, and the burrs may affect the assembly effect of the metal raw materials during subsequent use of the raw materials.

[0053] Based on the above embodiment 1, 2 or 3, refer to Figure 3 、 Figure 4 、A Tu 5、 Figure 6 and Figure 11, one side of the positioning frame 2 is rotatably connected to the first protective cover 19, and the second protective cover 29 is detachably installed on one side of the lower mounting shell 11, which is convenient for protecting the transmission synchronous belt 18 and the first transmission belt 28. Dust covers 67 are fixedly installed on both sides of the fourth mounting plate 64, and one side of the dust cover 67 is fixedly installed to the inner side of the transmission box 9 to prevent external dust or foreign matter from entering the interior of the transmission box 9 and affecting its use. The inner circular wall surface of the mounting cap 31 is fixedly sleeved with a first limiting ring 34, and the inner circular wall surface of the first limiting ring 34 is movably sleeved with the first connecting column 32. The inner circular wall surface of the mounting tube 30 is fixedly sleeved with a second limiting ring 38, and the inner circular wall surface of the second limiting ring 38 is movably sleeved with the second connecting column 36 to prevent misalignment between the first connecting column 32 and the mounting cap 31 and the second connecting column 36 and the mounting tube 30.

[0054] Working principle: Please refer to Figures 1-11 As shown, when in use, the staff transports the pipe to the inside of the hydraulic three-jaw chuck 13 through the feeding assembly. At this time, the staff fixes one end of the pipe through the multiple claws of the hydraulic three-jaw chuck 13. After the above steps are completed, the staff uses the cutting machine 41 and the second electric push rod 66, and the contraction of the telescopic rod of the second electric push rod 66 will drive the second mounting frame 40 to rotate. At this time, the cutting machine 41 on the top surface of the second mounting frame 40 will move downward and cut the pipe. When the pipe cutting is completed, the staff uses the moving assembly to make the first mounting plate 3 shift quantitatively, and at the same time retract the remaining pipe through the feeding assembly, and then the slide 45 on the top of the first mounting plate 3 will shift accordingly, and then the staff drives the second slide block 42 to slide by the contraction of the telescopic rod of the first electric push rod 44. At this time, the second slide block 42 moves along the inclined surface at the bottom of the slide block 45 to lift the slide block 45, and then the slide block 4 The two forming grinding heads 54 at the top of the 5 will rise and move to the position of the pipe cutting surface, and then the staff will reverse the above steps, and then, driven by the moving assembly and the feeding assembly, one forming grinding head 54 will be put on the outside of the pipe cutting surface fixed on the hydraulic three-jaw chuck 13, and the remaining pipe will be pushed into the inside of the other forming grinding head 54 by the feeding assembly. At this time, the staff will use the third mounting plate 46 and the first motor 16, and then the hydraulic three-jaw chuck 13 will drive the pipe inside it to rotate through the transmission effect of the first motor 16 and the transmission timing belt 18, and then the two forming grinding heads 54 will rotate through the transmission effect of the electric motor 48 and the second transmission belt 52. At this time, the two forming grinding heads 54 will grind the two cutting surfaces of the pipe to remove burrs on its inner and outer wall surfaces, thereby achieving the effect of cutting the pipe and facilitating the removal of burrs on its inner and outer walls.
