[0002] Heat exchange tubes are a key component in heat exchangers, primarily used to transfer heat between two fluids. During manufacturing, heat exchange tubes require a straightening device for straightening. Straightened heat exchange tubes ensure smooth fluid flow, uniform heat transfer, precise coordination with other components, and resistance to pressure and temperature changes, thereby improving equipment performance and lifespan. Existing heat exchange tube straightening devices often require workers to pull one end of the heat exchange tube along a straightening assembly to achieve the straightening process. However, this method is labor-intensive and inefficient. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a heat exchange tube straightening device, which solves the problem that existing heat exchange tube straightening devices often require workers to pull one end of the heat exchange tube to move it on the straightening component to achieve the straightening work, but this method is labor-intensive and has low work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat exchange tube straightening device, comprising a base plate, a vertical plate fixedly connected to the top of the base plate, four columns fixedly connected to the top of the base plate, a horizontal plate fixedly connected to the top of the four columns, four fixed straightening rollers rotatably connected to the vertical plate and the horizontal plate via a rotating shaft, three rectangular holes provided on the vertical plate and the horizontal plate, a movable block provided inside the rectangular hole, and a movable straightening roller rotatably connected to the movable block via a rotating shaft; A box is fixedly connected to the top of the base plate. A bidirectional threaded rod is rotatably connected to the inside of the box via bearings. Two movable plates are threaded onto the bidirectional threaded rod. A fixed column is fixedly connected to the inside of the box. An L-shaped plate is fixedly connected to the movable plate. There are two L-shaped plates. A rotating shaft is rotatably connected to both L-shaped plates via bearings. A rotating column is rotatably connected to one L-shaped plate via bearings. A connecting rod is rotatably connected to the other L-shaped plate via bearings. A pressure roller is fixedly connected to one end of the rotating shaft, a first bevel gear is fixedly connected to the other end of the rotating shaft, a second bevel gear is fixedly connected to the bottom end of the rotating column, a first square hole is provided on the rotating column, a third bevel gear is fixedly connected to the connecting rod, a first square rod is fixedly connected to the top end of the connecting rod, a second square rod is fixedly connected to the bottom end of the connecting rod, a motor is fixedly connected to the top of the housing, a rotating rod is fixedly connected to the output end of the motor, and a second square hole is provided on the rotating rod.

[0005] As a further embodiment of this utility model: the fixed column passes through the two movable plates, and the movable plates are slidably connected to the fixed column.

[0006] As a further embodiment of this utility model: the number of the first bevel gears is two, one of which meshes with the third bevel gear, and the other of which meshes with the second bevel gear.

[0007] As a further embodiment of this utility model: the second square rod is slidably connected inside the first square hole, the first square rod is slidably connected inside the second square hole, and three screws are rotatably connected to the vertical plate through bearings, and the moving block is threadedly connected to the screws.

[0008] As a further embodiment of this utility model: a first knob is fixedly connected to the top of the screw, and a second knob is fixedly connected to the top of the bidirectional threaded rod. Both the first knob and the second knob have several grooves.

[0009] As a further embodiment of this utility model: two slide bars are fixedly connected to the moving block, and a slide groove is provided inside the rectangular hole corresponding to the position of the slide bars.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This heat exchange tube straightening device comprises a bidirectional threaded rod, a movable plate, a first square rod, a second square rod, a first square hole, a first bevel gear, a second bevel gear, a third bevel gear, and a second square hole. In use, the heat exchange tube is placed between multiple sets of movable straightening rollers and fixed straightening rollers, and one end of the heat exchange tube is pulled between two clamping rollers. Turning the second knob rotates the bidirectional threaded rod. Because the upper and lower threads of the bidirectional threaded rod are in opposite directions, and the two movable plates are threaded onto opposite threaded areas on the bidirectional threaded rod, the rotation of the bidirectional threaded rod causes the two movable plates, the L-shaped plate, and the clamping rollers to move closer together, clamping the heat exchange tube. Simultaneously, the second square rod and the first square rod respectively... The first square hole and the second square hole slide inside each other. At this time, the motor is started to drive the rotating rod to rotate. Due to the square design of the second square hole, the first square rod, the second square rod and the first square hole, the rotation of the rotating rod can drive the third bevel gear and the second bevel gear to rotate synchronously. The two first bevel gears mesh with the third bevel gear and the second bevel gear respectively. Therefore, the two first bevel gears, the rotating shaft and the pressure roller rotate synchronously. The two pressure rollers rotate in opposite directions. As the two pressure rollers rotate, the heat exchange tube can be conveyed. The device clamps the heat exchange tube with two pressure rollers and realizes the automatic conveying of the heat exchange tube by two pressure rollers rotating in opposite directions. This facilitates the straightening work, reduces labor intensity and improves work efficiency. 2. This heat exchange tube straightening device, by setting a screw, a moving block, and a moving straightening roller, allows the screw to rotate when the position of the moving straightening roller needs to be adjusted. Since the moving block is threaded onto the screw, the rotation of the screw can drive the moving block and the moving straightening roller to move along the length of the screw, thereby completing the position adjustment of the moving straightening roller. By adjusting the position of the moving straightening roller, this device can adjust the distance between the moving straightening roller and the fixed straightening roller according to the actual situation, so that the heat exchange tube can pass smoothly.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-6 As shown, this utility model provides a technical solution: a heat exchange tube straightening device, including a base plate 1, a vertical plate 2 fixedly connected to the top of the base plate 1, four columns 5 fixedly connected to the top of the base plate 1, and a horizontal plate 6 fixedly connected to the top of the four columns 5. Four fixed straightening rollers 4 are rotatably connected to the vertical plate 2 and the horizontal plate 6 through a rotating shaft. Three rectangular holes 12 are provided on the vertical plate 2 and the horizontal plate 6. A moving block 9 is provided inside the rectangular hole 12. Two slide bars 10 are fixedly connected to the moving block 9. Because of the slide bars 10, when the moving block 9 moves, the slide bars 10 will slide inside the slide groove 13. The slide bars 10 and the slide groove 13 play a role in limiting and guiding the moving block 9 and the moving straightening roller 11, improving the stability and accuracy of the movement of the moving block 9 and the moving straightening roller 11. The slide groove 13 is provided inside the rectangular hole 12 corresponding to the position of the slide bar 10.

[0014] A movable straightening roller 11 is rotatably connected to the movable block 9 via a rotating shaft. A box 7 is fixedly connected to the top of the base plate 1. A bidirectional threaded rod 14 is rotatably connected to the inside of the box 7 via a bearing. Two movable plates 16 are threadedly connected to the bidirectional threaded rod 14. A fixed column 15 is fixedly connected to the inside of the box 7. Because of the fixed column 15, when the movable plate 16 moves, the movable plate 16 will slide on the fixed column 15. The fixed column 15 can limit and guide the movable plate 16, improving the stability and accuracy of the movement of the movable plate 16. The fixed column 15 passes through the two movable plates 16, and the movable plates 16 are slidably connected to the fixed column 15. Two L-shaped plates 18 are fixedly connected to the movable plates 16. A rotating shaft 21 is rotatably connected to each of the two L-shaped plates 18 via a bearing.

[0015] One of the L-shaped plates 18 is rotatably connected to a rotating column 26 via a bearing, and the other L-shaped plate 18 is rotatably connected to a connecting rod 28 via a bearing. One end of the rotating shaft 21 is fixedly connected to a pressure roller 22, and the other end of the rotating shaft 21 is fixedly connected to a first bevel gear 23. There are two first bevel gears 23, one of which meshes with a third bevel gear 25, and the other meshes with a second bevel gear 24. The bottom end of the rotating column 26 is fixedly connected to a second bevel gear 24, and a first square hole 27 is opened on the rotating column 26. The third bevel gear 25 is fixedly connected to the connecting rod 28, and a first square rod 29 is fixedly connected to the top end of the connecting rod 28.

[0016] A second square rod 30 is fixedly connected to the bottom end of the connecting rod 28. Because of the square design of the second square rod 30 and the first square hole 27, the rotation of the second square rod 30 can drive the rotating column 26 and the second bevel gear 24 to rotate, ensuring the normal operation of subsequent work. A motor 19 is fixedly connected to the top of the housing 7. A rotating rod 20 is fixedly connected to the output end of the motor 19. A second square hole 31 is opened on the rotating rod 20, and the second square rod 30 is slidably connected inside the first square hole 27. The first square rod 29 is slidably connected inside the second square hole 31. Three screws 3 are rotatably connected to the vertical plate 2 via bearings. The moving block 9 is threadedly connected to the screws 3. The top of the screw 3 is fixedly connected to the first knob 8. The top of the bidirectional threaded rod 14 is fixedly connected to the second knob 17. Both the first knob 8 and the second knob 17 are provided with several grooves. By setting the grooves, the roughness of the first knob 8 and the second knob 17 can be increased, which can increase the friction and make it easier for personnel to rotate the first knob 8 and the second knob 17, thus improving the ease of operation.

[0017] The working principle of this utility model is as follows: In use, the heat exchange tube is placed between multiple sets of movable straightening rollers 11 and fixed straightening rollers 4, and one end of the heat exchange tube is pulled between two clamping rollers 22. At this time, turning the second knob 17 drives the bidirectional threaded rod 14 to rotate. Since the upper and lower threads of the bidirectional threaded rod 14 are in opposite directions, and the two movable plates 16 are respectively threaded onto opposite threaded areas on the bidirectional threaded rod 14, when the bidirectional threaded rod 14 rotates, the two movable plates 16, the L-shaped plate 18, and the clamping rollers 22 will move closer to each other, and the two clamping rollers 22 will clamp the heat exchange tube. At the same time, the second square rod 30 and the first square rod 29 slide inside the first square hole 27 and the second square hole 31, respectively. At this time, the motor 19 is started to drive the rotating rod 20 to rotate. Since the second square hole 31, the first square rod 29, the second square rod 30, and the first square hole 27 are connected, the rotation of the rotating rod 20 is achieved. The square design allows the rotating rod 20 to rotate synchronously with the third bevel gear 25 and the second bevel gear 24. The two first bevel gears 23 mesh with the third bevel gear 25 and the second bevel gear 24 respectively, causing the two first bevel gears 23, the rotating shaft 21, and the pressure roller 22 to rotate synchronously. The two pressure rollers 22 rotate in opposite directions, thus conveying the heat exchange tube. The heat exchange tube moves between multiple sets of movable straightening rollers 11 and fixed straightening rollers 4 to achieve straightening. When the position of the movable straightening roller 11 needs adjustment, rotating the first knob 8 drives the screw 3 to rotate. Since the movable block 9 is threaded onto the screw 3, rotating the screw 3 drives the movable block 9 and the movable straightening roller 11 to move along the length of the screw 3, thereby completing the position adjustment of the movable straightening roller 11.
