Description

Technical Field

[0001] This utility model relates to the technical field of U-shaped pipe bending equipment, specifically a U-shaped pipe crimping device for a cooler. Background Technology

[0002] Cooler U-tubes are tubular rubber products used to transport gases, liquids, slurries, or granular materials. They consist of inner and outer rubber layers and a reinforcing layer. Cooler U-tubes typically have metal fittings at both ends for easy connection to other piping systems. During manufacturing, the outer tubing at both ends of the hose is first ground off, and then the metal fittings are crimped to both ends of the cooler U-tube.

[0003] According to a published application for a hose crimping device (publication number: CN220995493U), by setting up a compression unit, after hoses of different diameters are inserted into the fixing ring, the air bladder is inflated through the inflation tube to make the air bladder bulge, thereby squeezing and fixing the hoses of different diameters. After cooperating with the clamping mechanism, the crimping operation can be performed quickly.

[0004] However, in actual use, the above-mentioned equipment can only process one end of the U-shaped tube before processing the other end. It cannot effectively adapt to U-shaped tubes with different curvatures, resulting in low processing efficiency. Furthermore, the airbags used to fix the tubes have become fatigued and worn after repeated use, requiring regular manual maintenance and replacement. In view of this, we propose a U-shaped bend crimping device for coolers. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A U-shaped bend crimping device for a cooler includes a base, a support leg fixedly connected to the lower surface of the base, a cover plate fixedly connected to the upper surface of the base, a groove formed on the upper surface of the base, a threaded connecting block slidably connected to the upper surface of the groove, and a fixing mechanism provided on the upper surface of the threaded connecting block, the fixing mechanism including:

[0007] A connecting post 1, the lower surface of which is fixedly connected to the upper surface of the threaded connecting block, a fixing ring fixedly connected to the upper surface of the connecting post 1, a slot being provided on the side wall of the fixing ring, and a telescopic rod being fixedly connected to the end of the slot away from the inner ring of the fixing ring.

[0008] A telescopic spring is sleeved on the outer surface of a telescopic rod. A receiving block is fixedly connected to one end of the telescopic rod near the inner ring of the fixed ring. A limit ring is fixedly connected to one end of the receiving block near the inner ring of the fixed ring. A sliding plate is slidably connected to the side wall of the slot.

[0009] Preferably, the limiting ring is provided with a synchronization mechanism inside. The synchronization mechanism includes a slot, which is opened at the end of the limiting ring. A connecting box is provided inside the slot. A rotating shaft is fixedly connected to the side wall of the connecting box. A gear is rotatably connected to the outer surface of the rotating shaft. A movable toothed plate meshes with the outer surface of the gear.

[0010] Preferably, the side wall of the threaded connecting block is fixedly connected to a locking mechanism, the inside of the threaded connecting block is threadedly connected to a threaded rod, one end of the threaded rod is rotatably connected to a positioning block, the other end of the threaded rod is fixedly connected to the output end of a motor, the side wall of the threaded connecting block is fixedly connected to a connecting plate, the upper surface of the connecting plate is fixedly connected to a receiving plate, and the upper surface of the groove is provided with a sliding groove.

[0011] Preferably, a second connecting column is fixedly connected to the upper surface of the receiving plate, a lower clamping ring is fixedly connected to the upper surface of the second connecting column, a receiving column is fixedly connected to the upper surface of the cover plate, a fixing plate is fixedly connected to the upper surface of the receiving column, a telescopic cylinder is fixedly connected through the upper surface of the fixing plate, and an upper clamping ring is fixedly connected to the output end of the telescopic cylinder.

[0012] Preferably, there are two sets of the locking mechanism, threaded connecting block, threaded rod, motor, positioning block, connecting plate, and receiving plate, and the two sets of the locking mechanism, threaded connecting block, threaded rod, motor, positioning block, connecting plate, and receiving plate are distributed in a mirror-symmetrical manner on the upper surface of the trench.

[0014] Preferably, the fixing ring, the upper clamping ring, and the lower clamping ring are located on the same axis.

[0015] Compared with the prior art, this utility model provides a U-shaped bend crimping device for a cooler, which has the following advantages:

[0016] 1. This U-shaped bend pipe crimping device for the cooler, through the setting of a fixing mechanism, in conjunction with a telescopic rod and a telescopic spring, drives a limiting ring to adaptively clamp the pipe. The rigid mechanical structure avoids the wear and aging problems caused by long-term use of the airbag. The slotted design inside the fixing ring, combined with the sliding plate, can automatically adjust the clamping range of the limiting ring according to changes in pipe diameter. While ensuring the positioning accuracy of the pipe axis, the rigid contact between the receiving block and the telescopic rod provides a stable clamping force, overcoming the defect of uneven clamping force caused by air pressure fluctuations in the airbag. It is especially suitable for high-precision crimping scenarios, significantly improving the service life of the equipment and processing stability.

[0017] 2. The U-shaped bend crimping device for this cooler features a synchronization mechanism that, in conjunction with the meshing transmission of gears and moving toothed plates, enables the coordinated adjustment of multiple sets of limit rings. When the telescopic rod on one side is compressed by the tube, the rotating shaft drives the gear to rotate and drives the moving toothed plate on the symmetrical side to move in the opposite direction, causing the limit rings at the symmetrical positions to synchronously produce equal displacements. This solves the problem of tube skewing caused by asynchronous actions, ensuring that the U-shaped bend remains axially aligned throughout the crimping process. Simultaneously, the connection box provides enclosed protection for the transmission structure, preventing foreign objects from interfering with the gear and toothed plate meshing, significantly improving the consistency and processing efficiency of the crimping process.

[0025] like Figures 1-6 As shown, this utility model provides a technical solution: a U-shaped bend crimping device for a cooler, including a base 1, a support leg 11 fixedly connected to the lower surface of the base 1, a cover plate 12 fixedly connected to the upper surface of the base 1, a groove 2 opened on the upper surface of the base 1, a threaded connecting block 22 slidably connected to the upper surface of the groove 2, and a fixing mechanism 3 provided on the upper surface of the threaded connecting block 22. The fixing mechanism 3 includes: a connecting column 31, a fixing ring 32, a groove 33, a telescopic rod 34, a telescopic spring 35, a receiving block 36, a limiting ring 37, and a sliding plate 38.

[0026] In one embodiment of this utility model, the lower surface of the connecting post 31 is fixedly connected to the upper surface of the threaded connecting block 22. A fixing ring 32 is fixedly connected to the upper surface of the connecting post 31. A slot 33 is provided on the side wall of the fixing ring 32. A telescopic rod 34 is fixedly connected to the end of the slot 33 away from the inner ring of the fixing ring 32. A telescopic spring 35 is sleeved on the outer surface of the telescopic rod 34. A receiving block 36 is fixedly connected to the end of the telescopic rod 34 near the inner ring of the fixing ring 32. A limit ring 37 is fixedly connected to the end of the receiving block 36 near the inner ring of the fixing ring 32. A sliding plate 38 is slidably connected to the side wall of the slot 33. A fixing mechanism is provided. 3. In conjunction with the telescopic rod 34 and the telescopic spring 35, the driving limit ring 37 adaptively clamps the pipe. The rigid mechanical structure avoids the wear and aging problems caused by long-term use of the airbag. The slotted design 33 inside the fixed ring 32, combined with the sliding plate 38, can automatically adjust the clamping range of the limit ring 37 according to the pipe diameter. While ensuring the positioning accuracy of the pipe axis, the rigid contact between the receiving block 36 and the telescopic rod 34 provides a stable clamping force, which overcomes the defect of uneven clamping force caused by air pressure fluctuations in the airbag. It is especially suitable for high-precision crimping scenarios, significantly improving the service life of the equipment and the processing stability.

[0027] In addition, a synchronization mechanism 4 is provided inside the limiting ring 37. The synchronization mechanism 4 includes a slot 41, which is opened at the end of the limiting ring 37. A connecting box 45 is provided inside the slot 41. A rotating shaft 42 is fixedly connected to the side wall of the connecting box 45. A gear 43 is rotatably connected to the outer surface of the rotating shaft 42. A movable toothed plate 44 meshes with the outer surface of the gear 43. By setting up the synchronization mechanism 4, the meshing transmission of the gear 43 and the movable toothed plate 44 realizes the linkage adjustment of multiple sets of limiting rings 37. When the telescopic rod 34 on one side is squeezed by the pipe, the rotating shaft 42 drives the gear 43 to rotate and drives the movable toothed plate 44 on the symmetrical side to move in the opposite direction, so that the limiting rings 37 in the symmetrical position generate equal displacements synchronously. This solves the problem of pipe skew caused by asynchronous action and ensures that the U-shaped bend is always axially aligned during the crimping process. At the same time, the connecting box 45 seals the transmission structure. The closed protection prevents foreign objects from interfering with the meshing of the gear tooth plate 43, significantly improving the consistency and processing efficiency of the crimping process. The threaded connecting block 22 is fixedly connected to the side wall with a locking mechanism 21. The threaded connecting block 22 is internally threaded with a threaded rod 23. One end of the threaded rod 23 is rotatably connected to a positioning block 25, and the other end of the threaded rod 23 is fixedly connected to the output end of a motor 24. The threaded connecting block 22 is fixedly connected to the side wall with a connecting plate 26. The upper surface of the connecting plate 26 is fixedly connected to a receiving plate 27. The upper surface of the groove 2 is provided with a sliding groove 28. The motor 24 drives the threaded rod 23 to rotate, thereby causing the threaded connecting block 22 to move. When the threaded connecting block 22 moves to the appropriate position, the locking mechanism 21 can lock the threaded connecting block 22. The fixing ring 32, the upper crimping ring 52, and the lower crimping ring 51 are on the same axis to ensure the accuracy of the crimping.

[0028] In this embodiment of the utility model, a connecting post 25 is fixedly connected to the upper surface of the receiving plate 27, and a lower clamping ring 51 is fixedly connected to the upper surface of the connecting post 25. A receiving post 53 is fixedly connected to the upper surface of the cover plate 12, and a fixing plate is fixedly connected to the upper surface of the receiving post 53. A telescopic cylinder 54 is fixedly connected through the upper surface of the fixing plate, and an upper clamping ring 52 is fixedly connected to the output end of the telescopic cylinder 54. The pipe to be processed can be processed through the upper clamping ring 52 and the lower clamping ring 51. The locking mechanism 21, threaded connecting block 22, threaded rod 23, motor 24, positioning block 25, connecting plate 26, and receiving plate 27 are provided in total. Two sets of locking mechanisms 21, threaded connecting blocks 22, threaded rods 23, motors 24, positioning blocks 25, connecting plates 26, and receiving plates 27 are mirror-symmetrically distributed on the upper surface of the groove 2. A sliding groove 13 is provided on the upper surface of the cover plate 12. A control panel 14 is hinged to the side wall of the base 1. The mirror-symmetrically distributed locking mechanisms 21, threaded connecting blocks 22, threaded rods 23, motors 24, positioning blocks 25, connecting plates 26, and receiving plates 27 can adapt to U-shaped tubes with different curvatures, and have better adaptability. The threaded connecting blocks 22 on both sides can be independently adjusted through the control panel 14 according to the actual effect.

[0029] In this utility model, during use, the U-shaped bend is first placed on the lower clamping ring 51, and the motors 24 on both sides are started to drive the threaded rod 23 to rotate, which drives the threaded connecting block 22 to slide along the groove 2 towards the center, which can adapt to most U-shaped tubes. The limiting rings 37 on both sides of the fixing ring 32 automatically clamp the two ends of the bend through the telescopic rod 34 and the telescopic spring 35. The gear 43 in the synchronization mechanism 4 is linked with the moving toothed plate 44 to ensure that the limiting rings 37 on both sides are tightened and positioned synchronously. Then, the telescopic cylinder 54 pushes the upper clamping ring 52 down, which together with the lower clamping ring 51 applies pressure to the bend to complete the clamping and forming. Throughout the process, the clamping force and clamping accuracy are controlled by adjusting parameters through the control panel 14 to achieve fast and accurate processing.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
