Description

Technical Field

[0001] This invention relates to the technical field of pipe processing, and in particular to a device for processing both ends of a pipe. Background Technology

[0002] As is well known, after pipes are manufactured, they need to be cut into sections for easy transportation. After cutting, both sides of the pipe have cut surfaces. Therefore, after cutting, the sides of the pipe need to be processed to reduce the sharpness of the cut surfaces. A search revealed Chinese patent CN21766527U, which discloses a steel-plastic composite pipe end processing device, including a worktable, a telescopic rod, a partition, a cylinder, a pressure roller, a drive motor, a double-headed motor, and a limiting mechanism. In use, the steel pipe needs to be placed on the worktable, and then the limiting mechanism will adjust the end of the steel pipe. The pipe is limited to prevent it from slipping out. In use, it was found that if the steel pipe is small in diameter and light in weight, it can be placed directly between the limiting mechanisms on the operating platform. If the steel pipe is heavy, a crane is needed to lift it and place it between the limiting mechanisms before the end of the pipe is processed. For pipes with larger diameters, not only is the diameter larger, but the weight is also correspondingly heavier. During the movement, using a crane is not safe, and the pipe is prone to rolling and is difficult to control, which may cause it to hit the operator or cause the larger diameter pipe itself to be bumped and deformed. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pipe end processing device, including a bottom frame, a support structure is provided at the upper middle position of the bottom frame, and movable processing structures are provided on both sides of the support structure;

[0007] The support structure includes a support frame connected to the bottom frame. Multiple support columns are slidably mounted on the support frame. Below the multiple support columns is a movable frame that slidably engages with the support frame. Multiple horizontal magnetic strips are mounted on the movable frame. The distance between the multiple horizontal magnetic strips and the top of the support frame decreases sequentially from the inside to the outside, forming a downward-convex arc-shaped structure.

The drive mechanism includes a screw rotatably connected to the support frame and a motor fixedly installed on the support frame. The output shaft of the motor is drivenly connected to the screw. A movable block is fixedly connected to the movable frame and threadedly connected to the screw.

[0009] Preferably, the multiple horizontal magnetic strips are connected to the movable frame via a height adjustment mechanism. The height adjustment mechanism includes a U-shaped frame that slides with the movable frame. The horizontal magnetic strips are embedded in the top of the U-shaped frame. Multiple slots arranged longitudinally are provided on both sides of the U-shaped frame. Multiple fixing posts that are adapted to the slots are slidably fitted on both sides of the interior of the movable frame. Adjustment blocks are fixedly connected to the fixing posts. Springs are sleeved on the fixing posts, and the two ends of the springs are fixedly connected to the movable frame and the adjustment blocks, respectively.

[0010] Preferably, the processing structure includes a feed frame that slides with the bottom frame. The feed frame and the bottom frame are connected by a feed assembly. The feed frame is provided with a clamping mechanism and a processing mechanism. The processing mechanism includes a rotating plate that is rotatably connected to the feed frame. A second motor that drives the rotating plate to rotate is fixedly connected to the feed frame. A processing roller group is connected to the rotating plate through the second feed assembly.

[0014] Preferably, it also includes a stabilizing rod fixedly installed on the feed frame, the stabilizing rod being slidably engaged with the bottom frame.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a pipe end processing device, which has the following beneficial effects:

[0017] The pipe-end processing device features a support structure for easy pipe support. Movable processing structures are located on both sides of the support structure, allowing for simultaneous processing at both ends of the pipe. Multiple support columns provide support, and the cooperation of horizontal magnetic strips and magnetic blocks helps to lift these columns. By sequentially shortening the distance from the top of the support frame from the inside out, the horizontal magnetic strips form a downward-convex arc shape. The repulsion between the magnetic strips and the magnetic blocks causes the support columns above them to also form a downward-convex arc shape, thus limiting the bottom of the pipe and preventing uncontrollable rolling. Moving the movable frame moves the horizontal magnetic strips, which in turn raises and lowers the support columns, allowing the pipe to roll in or out of the processing area. This convenient movement of the pipe, combined with the control over its movement, improves safety and reduces labor. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 The present invention provides a pipe end processing device, including a bottom frame 1, a support structure provided at the upper middle position of the bottom frame 1, and movable processing structures provided on both sides of the support structure.

[0027] The support structure includes a support frame 2 connected to the bottom frame 1. Multiple support columns 3 are slidably mounted on the support frame 2. A movable frame 4 that slides and cooperates with the support frame 2 is located below the multiple support columns 3. Multiple horizontal magnetic strips 5 are mounted on the movable frame 4. The distance between the multiple horizontal magnetic strips 5 and the top of the support frame 2 decreases sequentially from the inside to the outside and forms a downward convex arc structure. A magnetic block 6 that is magnetically repelled by the horizontal magnetic strips 5 is fixedly connected to the bottom of each of the multiple support columns 3.

[0028] Specifically, it also includes a drive mechanism for moving the movable frame 4. The drive mechanism includes a screw 7 rotatably connected to the support frame 2 and a motor 8 fixedly installed on the support frame 2. The output shaft of the motor 8 is connected to the screw 7. A movable block 9, which is threadedly connected to the screw 7, is fixedly connected to the movable frame 4. Furthermore, the output shaft of the motor 8 and the screw 7 are driven by a sprocket and chain or gear meshing. In this case, the sprocket and chain drive is preferred. When the motor 8 is started, the output shaft of the motor 8 rotates clockwise or counterclockwise, which facilitates the clockwise or counterclockwise rotation of the screw 7. Due to the sliding fit between the movable frame 4 and the support frame 2, and the threaded connection between the screw 7 and the movable block 9, the movable block 9 and the movable frame 4 are driven to move back and forth along the support frame 2.

[0029] Specifically, multiple horizontal magnetic strips 5 are connected to the movable frame 4 via a height adjustment mechanism. The height adjustment mechanism includes a U-shaped frame 10 that slides with the movable frame 4. The horizontal magnetic strips 5 are embedded in the top of the U-shaped frame 10. Multiple slots 11 arranged longitudinally are provided on both sides of the U-shaped frame 10. Multiple fixing posts 12 that are adapted to the slots 11 are slidably fitted on both sides of the interior of the movable frame 4. Adjusting blocks 13 are fixedly connected to the fixing posts 12. Springs 14 are sleeved on the fixing posts 12. The two ends of the springs 14 are respectively connected to the movable frame 4. The moving frame 4 and the adjusting block 13 are fixedly connected. By simultaneously pulling the adjusting blocks 13 on both sides of the U-shaped frame 10 towards the middle and pulling the fixed column 12 out of the slot 11, the spring 14 is compressed. Then the height of the U-shaped frame 10 can be adjusted. When the height is adjusted to the required height and the slot 11 is aligned with the corresponding slot 11, the two adjusting blocks 13 are released. Under the action of the spring 14's rebound force, the fixed column 12 is pushed into the slot 11. By adjusting the height, it is convenient to move pipes of different diameters.

[0030] Specifically, the processing structure includes a feed frame 15 that slides with the base frame 1. The feed frame 15 is connected to the base frame 1 via a feed assembly 16. The feed frame 15 is equipped with a clamping mechanism and a processing mechanism. The processing mechanism includes a rotating plate 17 rotatably connected to the feed frame 15. A second motor 18 that drives the rotating plate 17 to rotate is fixedly connected to the feed frame 15. A processing roller group is connected to the rotating plate 17 via a second feed assembly 19. The support frame 2 is connected to the base frame 1 via a third feed assembly 20. When the pipe is moved to the middle processing position of the support frame 2... Then, the support frame 2 is height-adjusted by the feed assembly 3 20, thereby aligning the pipe fitting with the rotation axis of the rotating plate 17. Then, the processing roller group is adjusted by the feed assembly 2 19 to a height where the processing roller group can contact the pipe. Then, the feed frame 15 is moved towards the pipe by the feed assembly 1 16, and the processing roller group contacts the end of the pipe. Then, the motor 2 18 is started, driving the rotating plate 17 and the processing roller group to rotate, thereby processing the end of the pipe. This device is applicable to pipes of different specifications and has a wide range of applications.

[0031] Specifically, the clamping mechanism includes a clamping rod 21 that slides with the top of the feed frame 15. One end of the clamping rod 21 is connected to the feed frame 15 via the feed assembly 22, and the other end of the clamping rod 21 is provided with a clamping block 23. The bottom of the clamping block 23 is provided with an anti-slip rubber plate 24. The feed assembly 16, feed assembly 29, feed assembly 30, and feed assembly 42 can all be fed by hydraulic cylinder or motor-driven screw. In this case, the hydraulic cylinder is preferred. The height of the clamping rod 21 can be easily adjusted by the feed assembly 42. When the feed frame 15 moves to one end of the pipe, the clamping rod 21 can be adjusted downward by the feed assembly 42, and then moved downward by the clamping block 23 and the anti-slip rubber plate 24. The pipe is clamped by the clamping block 23, the anti-slip rubber plate 24, and the multiple support columns 3 below.

[0032] Specifically, the processing roller assembly includes a slide plate 25 that slides with the rotating plate 17 and two processing rollers 26. The slide plate 25 is connected to the rotating plate 17 via a second feeding assembly 19. A fixed plate 27 is detachably connected to the slide plate 25. Both processing rollers 26 are rotatably connected to the fixed plate 27. Furthermore, the fixed plate 27 can be connected by bolts or clips. In this case, bolts are preferred to facilitate the disassembly of the two processing rollers 26. The second feeding assembly 19 facilitates the sliding adjustment of the slide plate 25 on the rotating plate 17, thereby making it suitable for processing pipes of different diameters.

[0033] Specifically, it also includes a guide assembly, which includes a guide frame 28 fixedly installed on the bottom frame 1. A sliding frame 29 fixedly connected to the support frame 2 is slidably fitted on the guide frame 28. The sliding fit between the guide frame 28 and the sliding frame 29 facilitates the increase of the stability of the support frame 2 and the bottom frame 1.

[0034] Specifically, it also includes a stabilizing rod 30 fixedly installed on the feed frame 15. The stabilizing rod 30 is slidably engaged with the bottom frame 1. By setting the stabilizing rod 30, the stabilizing rod 30 moves together with the feed frame 15 while it moves, which helps to increase the stability of the feed frame 15.

[0035] In use, place the processing devices at both ends of the pipe in the desired position, then place the pipe onto multiple support columns 3 from one side of the support structure. Start motor 8, causing its output shaft to rotate counter-clockwise, which in turn drives screw 7 to rotate counter-clockwise. Due to the sliding fit between the moving frame 4 and the support frame 2, and the threaded connection between screw 7 and moving block 9, moving block 9 and moving frame 4 move backward along the support frame 2. When the pipe reaches the middle position, i.e., the processing area, adjust the height of the support frame 2 using feed assembly 3 20, aligning the pipe axis with the rotation axis of the rotating plate 17. Then, adjust the processing roller group to a height where it can contact the pipe using feed assembly 2 19. Finally, move the feed frames 15 on both sides towards the pipe using feed assemblies 16 on both sides, ensuring that the processing roller groups on both sides contact the ends of the pipe. Then, the clamping rod 21 is adjusted downward by the feed assembly 22, and then the clamping block 23 and the anti-slip rubber plate 24 are moved downward. The pipe is clamped by the clamping block 23, the anti-slip rubber plate 24 and the multiple support columns 3 below. Then, the motors 18 on both sides are started to drive the rotating plate 17 and the processing roller group to rotate, thereby processing the ends of both sides of the pipe. After processing, the clamping block 23 is moved upward by the feed assembly 22 on both sides, and the feed frame 15 is moved to both sides by the feed assembly 20 on both sides. Then, the motor 8 is started again to make the output shaft of the motor 8 rotate counterclockwise, so that the pipe continues to move backward from the middle position, i.e., the processing area. When it moves to the rear side of the support structure, the pipe can be unloaded. Then, the output shaft of the motor 8 is rotated clockwise to drive the moving frame 4 to the front side. Then, the above operation is repeated to process the next pipe.
