Description

Technical Field

[0001] This utility model relates to the field of U-tube production technology, specifically to a U-tube internal dimension correction machine. Background Technology

[0002] During the production and processing of U-shaped steel pipes, some U-shaped steel pipes may have dimensional deviations. Because U-shaped steel pipes are U-shaped, the internal dimensions of the U-shaped pipes are particularly prone to deviations during the production process. When the internal dimensions of the U-shaped steel pipes deviate, they need to be corrected.

[0003] Currently, most existing U-tube calibration methods still rely on manual tapping. This manual calibration method is cumbersome, time-consuming, labor-intensive, and inefficient. To address these issues, we propose a U-tube internal dimension calibration machine. Utility Model Content

[0004] The purpose of this invention is to provide a U-tube internal dimension correction machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a U-shaped tube internal dimension correction machine, comprising:

[0006] A calibration table is provided with two symmetrically arranged mounting seats. Multiple calibration rollers are rotatably mounted on the top wall of each mounting seat via a rotating shaft. A first fixed seat is fixedly welded to the top wall of the calibration table near both the front and rear walls. A first hydraulic rod is fixedly mounted on the first fixed seat. An L-shaped mounting bracket is fixedly mounted on the output end of the first hydraulic rod. Multiple extrusion rollers are rotatably mounted on the L-shaped mounting bracket via a rotating shaft. The extrusion rollers are aligned with the calibration rollers. A second fixed seat is fixedly welded to the middle of the top wall at one end of the calibration table. A second hydraulic rod is fixedly mounted on the second fixed seat. A push plate is fixedly mounted on the output end of the second hydraulic rod.

[0007] Preferably, a top plate is fixedly welded to the top wall of the push plate, a pressure plate is provided below the top plate, a stud is rotatably installed on the pressure plate, the stud is threaded to the top plate, and two guide posts are fixedly welded to the pressure plate, the guide posts are slidably connected to the top plate.

[0008] Preferably, the calibration table has two symmetrically arranged through slots, and the same bidirectional lead screw is rotatably installed in the two through slots. A fixing post is fixedly welded in the through slots. The mounting seat is threadedly connected to the bidirectional lead screw through a screw hole, and the mounting seat is slidably connected to the fixing post through a through hole.

[0009] Preferably, a servo motor is fixedly installed on the front side wall of the calibration platform, and the output end of the servo motor is connected to a bidirectional lead screw drive.

[0010] Preferably, a controller is fixedly installed on the front side wall of the calibration platform, and the controller is electrically connected to the first hydraulic rod, the second hydraulic rod and the servo motor via wires.

[0011] Preferably, a handwheel is fixedly installed at the top of the stud.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When using this utility model, first place the bent end of the U-shaped tube at the push plate position and lock it on the calibration table surface by the pressure plate. Then, start the second hydraulic rod to push both ends of the U-shaped tube to the positions of the two sets of calibration rollers respectively. Then, start the two first hydraulic rods at the same time to drive the two sets of extrusion rollers to squeeze the two ends of the U-shaped tube so that they are in contact with the corresponding calibration rollers. Finally, start the second hydraulic rod again so that the push plate pushes the U-shaped tube to slide between the two sets of calibration rollers and extrusion rollers to achieve the correction of the internal size of the U-shaped tube. The operation is simple, saves time and effort, and improves the working efficiency of U-shaped tube internal size correction.

[0014] 2. This utility model uses a servo motor to drive a bidirectional lead screw to rotate, causing the two mounting seats to move towards or away from each other in the corresponding through slots. This facilitates the adjustment of the distance between the two mounting seats, i.e., the distance between the two sets of correction rollers, thereby making it easier to correct the internal dimensions of U-shaped tubes with various size requirements and greatly improving the applicability of the correction machine.

[0020] 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a U-shaped tube internal dimension correction machine, comprising:

[0022] A calibration table 1 is provided, on which two symmetrically arranged mounting seats 2 are provided. Multiple calibration rollers 3 are rotatably mounted on the top wall of the mounting seats 2 via a rotating shaft. A first fixing seat 4 is fixedly welded to the top wall of the calibration table 1 near the front and rear walls. A first hydraulic rod 5 is fixedly mounted on the first fixing seat 4. An L-shaped mounting bracket 6 is fixedly mounted on the output end of the first hydraulic rod 5. Multiple extrusion rollers 7 are rotatably mounted on the L-shaped mounting bracket 6 via a rotating shaft. The extrusion rollers 7 are aligned with the calibration rollers 3. A second fixing seat 8 is fixedly welded to the middle of the top wall of one end of the calibration table 1. A second hydraulic rod 9 is fixedly mounted on the second fixing seat 8. A push plate 10 is fixedly mounted on the output end of the second hydraulic rod 9.

[0023] A top plate 11 is fixedly welded to the top wall of the push plate 10. A pressure plate 12 is provided below the top plate 11. A stud 13 is rotatably installed on the pressure plate 12. The stud 13 is threadedly connected to the top plate 11. Two guide posts 14 are fixedly welded to the pressure plate 12. The guide posts 14 are slidably connected to the top plate 11. When the stud 13 rotates, it can drive the pressure plate 12 to move up and down, so as to press the pressure plate 12 onto the top wall of the U-shaped tube and prevent the U-shaped tube from tilting up when the push plate 10 pushes the U-shaped tube.

[0024] The calibration table 1 has two symmetrically arranged through slots 15, and the same bidirectional lead screw 16 is rotatably installed in the two through slots 15. A fixing post 17 is fixedly welded in the through slot 15. The mounting seat 2 is threadedly connected to the bidirectional lead screw 16 through the screw hole and slidably connected to the fixing post 17 through the through hole. When the bidirectional lead screw 16 rotates, it can drive the two mounting seats 2 to move towards or away from each other in the corresponding through slots 15, thereby facilitating the adjustment of the distance between the two mounting seats 2.

[0025] A servo motor 18 is fixedly installed on the front side wall of the calibration platform 1, and the output end of the servo motor 18 is connected to the bidirectional lead screw 16 for transmission.

[0026] A controller 19 is fixedly installed on the front side wall of the calibration platform 1. The controller 19 is electrically connected to the first hydraulic rod 5, the second hydraulic rod 9 and the servo motor 18 via wires. The controller 19 is used to control the operation of the first hydraulic rod 5, the second hydraulic rod 9 and the servo motor 18.

[0027] A handwheel 20 is fixedly installed at the top of the stud 13, which facilitates the rotation of the stud 13.

[0028] Working principle: When using this utility model, the bent end of the U-shaped tube is first placed at the push plate 10, and locked on the table surface of the correction table 1 by the pressure plate 12. The second hydraulic rod 9 is activated to push the two ends of the U-shaped tube to the positions of the two sets of correction rollers 3 respectively. Then, the two first hydraulic rods 5 are activated at the same time to drive the two sets of extrusion rollers 7 to squeeze the two ends of the U-shaped tube so that they are in contact with the corresponding correction rollers 3. Finally, the second hydraulic rod 9 is activated again, so that the push plate 10 pushes the U-shaped tube to slide between the two sets of correction rollers 3 and the extrusion rollers 7 to correct the internal size of the U-shaped tube. The operation is simple, time-saving and labor-saving, and improves the working efficiency of U-shaped tube internal size correction. The servo motor 18 can drive the bidirectional lead screw 16 to rotate, so that the two mounting seats 2 can move towards or away from each other in the corresponding through grooves 15, thereby facilitating the adjustment of the distance between the two mounting seats 2, that is, the adjustment of the distance between the two sets of correction rollers 3. This makes it easy to correct the internal size of U-shaped tubes with various size requirements, greatly improving the applicability of the correction machine.
