A first motor 6 is fixedly installed at one end of the seat 3, and the output end of the first motor 6 is fixedly connected to the end of the fixed roller 4. A hydraulic cylinder 7 is fixedly installed at the middle position of the workbench 1, and a second mounting seat 8 is fixedly installed at the movable end of the hydraulic cylinder 7. A polishing roller 9 is rotatably installed at the middle of the second mounting seat 8 through an axle pin. A second motor 10 is fixedly installed at one end of the second mounting seat 8, and the output end of the second motor 10 is fixedly connected to the end of the polishing roller 9. Two groups of first mounting seats 3 are distributed at both ends of the polishing roller 9. One group of polishing rollers 9 is used to transport the metal pipes before polishing, and one group of polishing rollers 9 is used to transport the metal pipes after polishing.

[0023] like Figures 1 to 5 As shown, rotating wheels 11 are equidistantly mounted in the middle of the support seat 2 .

[0024] This facilitates the metal tube to slide stably in the middle of the bearing seat 2 .

[0025] like Figures 1 to 5 As shown, a limit rod 12 is symmetrically fixedly installed in the middle part of the workbench 1 corresponding to the position of the fixed roller 4, and a movable plate 13 is slidably installed between the two limit rods 12. A bidirectional screw 14 is rotatably installed on the workbench 1 at a position corresponding to the two limit rods 12 through a bearing, and the bidirectional screw 14 is threadedly connected to the movable plate 13. The first mounting seat 3 is installed on one side of the movable plate 13, and an extrusion motor 15 is fixedly installed on one side of the workbench 1 corresponding to the position of the bidirectional screw 14, and the output end of the extrusion motor 15 is fixedly connected to one end of the bidirectional screw 14.

[0026] The bidirectional screw 14 is driven to rotate by the extrusion motor 15, and the bidirectional screw 14 is threadedly connected to the movable plate 13 and the limiting rod 12, so that the limiting of the movable plate 13 drives the first mounting seat 3 to approach each other, and the inclined wheel 5 outside the fixed roller 4 contacts and squeezes the metal tube, which is used to locate the position of the metal tube.

[0027] like Figures 1 to 5 As shown, a positioning rod 16 is symmetrically fixedly installed on one side of the first mounting seat 3 away from the fixed roller 4, a positioning hole 17 is opened on the movable plate 13 at a position corresponding to the positioning rod 16, and the positioning hole 17 is slidably connected to the positioning rod 16, and a pressure relief spring 18 is sleeved on the outer side of one end of the positioning rod 16 away from the first mounting seat 3, one end of the pressure relief spring 18 is fixedly connected to the end of the positioning rod 16 away from the first mounting seat 3, and the other end of the pressure relief spring 18 is fixedly connected to one side of the movable plate 13.

[0028] When the inclined wheel 5 outside the fixed roller 4 contacts and squeezes the metal tube, the positioning rod 16 on the side of the first mounting seat 3 will slide inside the positioning hole 17. At this time, the pressure relief spring 18 is in an elongated state, which is used to prevent the inclined wheel 5 from excessively squeezing the metal tube while the inclined wheel 5 outside the fixed roller 4 has a certain squeezing force on the metal tube.

[0029] like Figures 1 to 5 As shown, baffles 19 are symmetrically fixedly mounted on both sides of the second mounting seat 8 .

[0030] The iron filings produced by polishing can be shielded.

[0031] like Figures 1 to 5 As shown, a feeding hole 20 is provided in the middle of the workbench 1 at a position corresponding to the baffle 19 .

[0032] Iron chips generated by polishing can fall to the discharge hole 20 under the shielding of the baffle 19, and the iron chips can be collected.

[0033] like Figures 1 to 5As shown, the distance between the two bearing seats 2 is smaller than the length of the metal tube.

[0034] Ensure that there are two bearing seats 2 to support the metal pipe.

[0035] The utility model provides a metal polishing device, and the specific working principle is as follows:

[0036] When the device is in use, the metal tube is placed between the two bearing seats 2, and then the metal tube is moved between a group of two fixed rollers 4. The polishing roller 9 is driven to descend to a position tangent to the metal tube through the operation of the hydraulic cylinder 7, and then the polishing roller 9 is driven to rotate through the second motor 10, and then the bidirectional screw 14 is driven to rotate through the extrusion motor 15. The bidirectional screw 14 is threadedly connected with the moving plate 13 and the limit rod 12, and the limit of the moving plate 13 drives the first mounting seat 3 to approach each other, so that the inclined wheel 5 on the outside of the fixed roller 4 contacts and squeezes the metal tube. At this time, the positioning rod 16 on one side of the first mounting seat 3 will slide inside the positioning hole 17. At this time, the decompression spring 18 is in an elongated state, which is used to prevent the inclined wheel 5 on the outside of the fixed roller 4 from having a certain extrusion force on the metal tube while preventing the inclined wheel 5 After the metal tube is over-extruded, the fixed roller 4 is driven to rotate by the first motor 6. Since the inclined directions of the inclined wheels 5 installed on the two fixed rollers 4 are opposite, and the rotation directions of the two fixed rollers 4 are the same, when the fixed roller 4 rotates and drives the inclined wheel 5 to rotate, the inclined wheel 5 on one fixed roller 4 will have a thrust to the left and downward on one side of the metal tube, and the inclined wheel 5 on the other fixed roller 4 will have a thrust to the left and upward on one side of the metal tube. Through the analysis of these two forces, the combination of the two forces can drive the metal tube to rotate, and will generate a rotational force that drives the metal tube to rotate. Therefore, the metal tube can be fed while the inclined wheel 5 squeezes and fixes the metal tube, which reduces the cumbersomeness of the use of the device. Finally, the polishing operation of the metal tube is realized through the contact between the polishing roller 9 and the metal tube.
