DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] See also Figures 1 to 7The present embodiment provides a cutting mechanism for the extrusion processing of power pipelines, including a base plate 1, and clamping components are provided on both sides of the top surface of the base plate 1, wherein one clamping component is fixed to the base plate 1, and the other clamping component is slidably connected to the base plate 1. A moving component is installed on one side of the top surface of the base plate 1 close to a clamping component slidably connected to the base plate 1, and the moving component is used to drive a clamping component slidably connected to the base plate 1 to move. A two-axis moving platform is installed in the middle of the top surface of the base plate 1, and the two-axis moving platform is located between the two clamping components. A cutting component is installed on the top of the two-axis moving platform, and a grinding component is installed on the cutting component.

[0026] A clamping assembly can be used to clamp the pipe while it is being polished at the polishing station after the pipe is cut. In combination with a two-axis moving platform and a polishing assembly, the pipe end can be polished directly after the pipe is cut, reducing subsequent processing steps and improving product production efficiency.

[0027] The utilization rate of the clamping components is greatly improved, which not only realizes the auxiliary cutting work but also the auxiliary grinding work. There is no need to add equipment for grinding work, which reduces the equipment investment cost of enterprises in the production and processing of power pipelines.

[0028] The clamping assembly includes a vertical cylinder 2 arranged on the top surface of the base plate 1, and the inner wall of the vertical cylinder 2 is symmetrically slidably connected with a clamping plate 3, and the inner wall of the vertical cylinder 2 is rotatably connected with a bidirectional screw 4 through a bearing. The two clamping plates 3 are respectively threadedly connected to the two ends of the bidirectional screw 4 through a first threaded hole. A first motor 5 is fixed to the top of the vertical cylinder 2, and the output end of the first motor 5 is fixed to the end of the bidirectional screw 4. Among the two clamping assemblies, the vertical cylinder 2 of the clamping assembly that is slidably connected to the base plate 1 is slidably connected to the surface of the base plate 1, and the vertical cylinder 2 of the clamping assembly that is fixedly connected to the base plate 1 is fixed to the surface of the base plate 1.

[0029] The clamping assembly works by driving the first motor 5 to rotate and driving the bidirectional screw 4 to rotate, so that the two clamping plates 3 are brought closer to each other and the power pipeline can be clamped by the clamping plates 3;

[0030] Specifically, the power pipeline is extruded by an extruder and then cooled and shaped in a cooling tank. After cooling and shaping, it is transported by a pipeline conveying device. The pipeline conveying device conveys the pipeline to the base plate 1. The pipeline first passes through a clamping assembly fixed to the base plate 1, and then passes through a clamping assembly slidably connected to the base plate 1. After the pipeline is moved into place, the two clamping assemblies work simultaneously to clamp the pipeline.

[0031] The moving component includes a second screw 6 rotatably connected to the top surface of the base plate 1 through a bearing, and the lower end of a vertical cylinder 2 slidably connected to the base plate 1 is threadedly connected to the second screw 6 through a second threaded hole. A second motor 7 is fixed to the top of the base plate 1, and one end of the second screw 6 is fixed to the output end of the second motor 7. When the moving component is working, the second motor 7 is driven to rotate, thereby driving the second screw 6 to rotate, thereby driving a clamping component slidably connected to the base plate 1 to move.

[0032] The two-axis mobile platform includes a Y-axis mobile plate 8 slidably connected to the top of the base plate 1 through a first linear slide rail, a Y-axis electric push rod 9 is fixed to the top of the base plate 1, and the extended end of the Y-axis electric push rod 9 is fixed to the outer wall of the Y-axis mobile plate 8, and the top of the Y-axis mobile plate 8 is slidably connected to the X-axis mobile plate 10 through a second linear slide rail, and an X-axis electric push rod 11 is fixed to the top of the Y-axis mobile plate 8, and the extended end of the X-axis electric push rod 11 is fixed to the outer wall of the X-axis mobile plate 10. By extending or retracting the Y-axis electric push rod 9, the Y-axis mobile plate 8 can be driven to slide, and by driving the X-axis electric push rod 11 to extend or retract, the X-axis mobile plate 10 can be driven to slide;

[0033] The X-axis moving plate 10 and the Y-axis moving plate 8 cooperate to drive the cutting assembly to move in two directions, so that the cutting assembly moves to complete the cutting of the pipe. Subsequently, the X-axis moving plate 10 and the Y-axis moving plate 8 cooperate to enable the two grinding assemblies to face the ends of the two sections of the cut pipe respectively.

[0034] After the cutting is completed and the positions of the two grinding assemblies are adjusted to face the ends of the two sections of pipes, the X-axis electric push rod 11 is driven to work, so that the X-axis movable plate 10 moves, and the grinding assembly is moved to the side close to the clamping assembly fixed to the base plate 1, so that the grinding assembly grinds the end of the pipe clamped by the clamping assembly fixed to the base plate 1, and then the moving assembly is driven to work at the same time, so that a clamping assembly sliding with the base plate 1 clamps the cut pipe and approaches the grinding assembly until it contacts the grinding assembly and is polished.

[0035] The cutting assembly includes a rotating shaft 12 rotatably connected to the top surface of the X-axis moving plate 10 through a bearing, a cutting blade 21 is fixed to the middle of the rotating shaft 12, a driven gear 13 is fixed to one end of the rotating shaft 12, a third motor 14 is fixed to the upper end of the X-axis moving plate 10, and a driving gear 15 meshing with the driven gear 13 is fixed to the output end of the third motor 14;

[0036] During cutting, the third motor 14 is driven to rotate, which drives the driving gear 15 to rotate the driven gear 13, thereby driving the rotating shaft 12 to rotate, so that the cutting blade 21 rotates at high speed to perform cutting work.

[0037] The grinding assembly includes grinding discs 16 symmetrically fixed to both ends of the rotating shaft 12. A groove 17 is formed on the side of the two grinding discs 16 facing away from each other. The groove 17 has an outer inclined surface 18 located on the outer ring portion and an inner inclined surface 19 located on the inner ring portion. A grinding sheet 20 is fixed to each of the outer inclined surface 18 and the inner inclined surface 19.

[0038] After the cutting is completed and the position of the grinding assembly is adjusted, that is, the two grinding discs 16 are respectively facing the ends of the two pipe sections, and then the X-axis 10 moving plate moves to move the grinding assembly to the side close to the clamping assembly fixed to the base plate 1, the grinding disc 16 close to the side contacts the end of the pipe section on the side, and the grinding sheet 20 on the outer inclined surface 18 can grind the outer edge of the pipe end, and the grinding sheet 20 on the inner inclined surface 19 can grind the inner edge of the pipe end;

[0039] Then, a clamping assembly sliding on the bottom plate 1 clamps the cut power pipe and moves to the side close to the grinding assembly, so that the end of the power pipe on this side contacts the groove 17 of the grinding disc 16 on this side for grinding.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
