[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figures 1 to 7As shown, the multifunctional metal pipe bending and polishing machine provided by this utility model includes a chassis 1. A fixed angle rod 4 is fixedly connected inside the chassis 1. A rotating shaft 2 is fixedly sleeved inside the fixed angle rod 4. A movable angle rod 3 is movably sleeved on the outer wall of the rotating shaft 2. The bottom end of the movable angle rod 3 is in contact with the top end of the chassis 1. A clamping mechanism is fixedly connected to the top ends of both the movable angle rod 3 and the fixed angle rod 4. A grinding mechanism is fixedly connected to both sides of the movable angle rod 3 and the fixed angle rod 4, and the top end of the grinding mechanism is at the same height as the clamping mechanism.

[0026] The grinding mechanism includes four sets of connecting guide rails 16, which are fixedly connected to both sides of the movable angle rod 3 and the fixed angle rod 4. Two sets of soft sleeve blocks 18 are fixedly connected to the back of two sets of connecting guide rails 16. Soft guide rails 17 are movably sleeved inside the two sets of soft sleeve blocks 18. The outer walls of the soft guide rails 17 are fixedly connected to the other two sets of connecting guide rails 16. Two sets of upright rods 11 are movably sleeved on the inner walls of the four sets of connecting guide rails 16. Four sets of upright rods 11 are fixedly sleeved on the outer walls of the two sets of upright rods 11. The four sets of limiting collars 23 are arranged in a square quadrangular array. Each of the four sets of limiting collars 23 has a connecting sleeve block 14 at its top. The inner wall of each of the four sets of connecting sleeve blocks 14 is movably sleeved with the upright 11. The outer wall of the motor 15 is fixedly connected to one side of the connecting sleeve block 14. A polishing brush 13 is fixedly sleeved on the outer wall of the output end of the motor 15. The outer wall of the polishing brush 13 is in contact with the other side of the connecting sleeve block 14. The outer walls of the two sets of uprights 11 are fixedly sleeved with transmission sleeve rods 25.

[0027] One set of uprights 11 has a gear 12 fixedly sleeved on its outer wall. The outer wall of the gear 12 meshes with an internal gear chain 19. The bottom end of the internal gear chain 19 is in contact with the connecting guide rail 16. One side of the inner wall of the internal gear chain 19 has a gear 20 meshing with it. The output end of the motor 21 is fixedly sleeved inside the gear 20. The outer wall of the motor 21 is fixedly connected to the bottom end of the chassis 1. The other side of the inner wall of the internal gear chain 19 has a limit post 22 movably sleeved on it. The bottom end of the limit post 22 is fixedly connected to the inner wall of one set of connecting guide rails 16.

[0028] A stop bar 6 is fixedly connected to the inner wall of the chassis 1, and the outer wall of the stop bar 6 is in contact with the outer wall of the internal gear chain 19.

[0029] In use, the bent pipe is first clamped by two sets of clamping mechanisms. The bend angle of the bent pipe is set at the top of the rotating shaft 2. By rotating the movable angle rod 3 around the rotating shaft 2, the two sets of clamping mechanisms can adapt to bent pipes with different bending angles. When polishing is required, motor 15 is started. The output end of motor 15 drives the polishing brush 13 at the front end to rotate, thereby polishing the outer wall of the bent pipe. At the same time, motor 21 is started. The output end of motor 21 drives motor 21 to rotate synchronously. The outer wall of motor 21 meshes with the internal gear chain 19. The internal gear chain 19 is driven to rotate between the motor 21 and the limiting post 22, which in turn drives the gear 12 meshing inside the internal gear chain 19 to rotate. The gear 12 moves along the internal gear chain 19 as a guide rail, which in turn drives the polishing brush 13 at the top to move and polish the surface of the pipe. The two sets of uprights 11 are connected by a transmission sleeve 25, so that the two sets of uprights 11 move synchronously to polish the outer wall of the bend. The polishing brush can be adjusted according to the bending angle and size of the pipe, and can fit the complex shape of the outer wall of the pipe very well.

[0030] Furthermore, the soft guide rail 17 is connected to the soft sleeve block 18 by setting the soft guide rail 17 and the soft sleeve block 18 are both made of soft material to adapt to the bending of pipes with different bending angles, thereby improving the utilization rate of the equipment.

[0031] By setting a limiting collar 23, the connecting sleeve 14 at the top remains stationary when the upright 11 rotates, ensuring that the polishing brush 13 is in close contact with the outer wall of the bend. Example

[0032] Based on Example 1, please refer to Figures 1 to 7 As shown, the clamping mechanism includes a bracket 5. The bottom end of the bracket 5 is fixedly connected to the fixed angle rod 4. A connecting block 8 is movably sleeved on the inner wall of the top end of the bracket 5. One end of a transmission rod 9 is hinged inside the connecting block 8. The other end of the transmission rod 9 is movably sleeved with a connecting rod 24. Both ends of the two sets of connecting rods 24 are fixedly sleeved with fixing claws 10. The bottom ends of the two sets of fixing claws 10 are respectively hinged to the two sides of the top end of the bracket 5.

[0033] The bracket 5 has a circular hole inside, and a connecting rod 7 is movably sleeved inside the circular hole. The top end of the connecting rod 7 is fixedly connected to the connecting block 8, and the bottom end of the connecting rod 7 is fixedly connected to the stop rod 6. Both sides of the stop rod 6 are slidably sleeved with the bracket 5.

[0034] When pipe clamping is required, push the stop rod 6 to slide upward inside the bracket 5. When the stop rod 6 moves to the top of the inner wall of the bracket 5, the connecting rod 7 drives the connecting block 8 to move upward simultaneously. The transmission rods 9 hinged on both sides of the connecting block 8 push the fixed claws 10 to unfold outward through two sets of sleeve rods 24, so that the clamping mechanism is in an open state to facilitate pipe clamping. The upward pushing force on the stop rod 6 is eliminated. Under the influence of gravity, the two sets of fixed claws 10 are driven to retract inward to clamp the pipe, ensuring the stability of the pipe during the grinding process and improving grinding accuracy and efficiency.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
