Description

Technical Field

[0001] This utility model relates to the field of heat exchanger component processing and bending technology, specifically to a bending device for heat exchanger component processing. Background Technology

[0002] A heat exchanger is a device that transfers some of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers are widely used as heaters, coolers, condensers, evaporators, and reboilers.

[0003] Bending is the process by which metal undergoes elastic deformation under the pressure of the upper or lower die of a bending machine, and then enters plastic deformation. In the initial stage of plastic bending, the sheet metal is freely bent.

The adjusting unit 3 includes a threaded rod 31, one side of which is rotatably connected to the mounting frame 21. Inside, a fixing nut 32 is threadedly connected to the inner side of the threaded rod 31. One end of the threaded rod 31 is threadedly connected to the inner side of the second power wheel 28. A movable frame 33 is threadedly connected to the inner side of the threaded rod 31. One end of the movable frame 33 is rotatably connected to a limiting plate 34. One side of the movable frame 33 is slidably engaged with the inner side of the mounting frame 21. One side of the limiting plate 34 is threadedly connected to the top surface of the mounting frame 21. The control motor 22 drives the gear 23 to rotate, which in turn drives the upper mold 25 inside the gear 24 to bend the pipe. At the same time, the upper mold 25 drives the belt 27 inside the first power wheel 26 to rotate, which in turn drives the threaded rod 31 at one end of the second power wheel 28 to rotate. Simultaneously, the threaded rod 31, limited by the limiting plate 34, causes the buckle 44 on the top surface of the movable frame 33 to move, thereby bending the pipe into a spiral shape. After bending, the limiting plate 34 is removed, and the bent spiral pipe can then be taken out. Example

[0032] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the forming unit 4 includes an electric telescopic rod 41, which is fixedly connected to the inner side of the movable frame 33. The telescopic end of the electric telescopic rod 41 is fixedly connected to a fixing groove 42. The inner side of the fixing groove 42 is slidably engaged with a lower mold 43. The inner side of the lower mold 43 is threadedly connected with a buckle 44. Subsequently, the electric telescopic rod 41 is controlled to drive the lower mold 43 inside the fixing groove 42 to fit against the bottom side of the pipe. During the rotation of the motor 22, the pipe is bent through the cooperation of the buckle 44 and the upper mold 25. At the same time, the lower mold 43 facilitates the disassembly and replacement of lower molds 43 with different spacings. Example

[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing unit 5 includes a fixing plate 51, which is fixedly connected to the inner side of the upper mold 25. A second motor 52 is fixedly connected to one side of the fixing plate 51. The output end of the second motor 52 is driven by a bidirectional threaded rod 53.

One end of the fixing bolt 57 is threadedly connected to the inside of the clamping block 54. By placing one end of the pipe to be bent inside the fixing plate 51, the second motor 52 is controlled to rotate, which in turn drives the clamping block 54 inside the bidirectional threaded rod 53 to rotate. At the same time, the anti-slip pad 56 on the inner side is driven to fit against the inner side of the pipe. The anti-slip pad 56 is provided to prevent damage to the inner side of the pipe during bending and to facilitate the removal and replacement of worn anti-slip pads 56.

[0034] The working principle of the bending device used for processing heat exchanger parts will be explained in detail below.

[0035] like Figure 1-5As shown, by placing one end of the pipe used for bending inside the fixed plate 51, the motor 52 is controlled to rotate, which in turn drives the clamping block 54 inside the bidirectional threaded rod 53 to rotate. Simultaneously, the anti-slip pad 56 on the inner side of the pipe is driven to conform to the inner side of the pipe. The anti-slip pad 56 prevents damage to the inner side of the pipe during bending and facilitates the removal and replacement of worn anti-slip pads 56. The electric telescopic rod 41 is controlled to drive the lower mold 43 inside the fixed groove 42 to conform to the bottom side of the pipe. Subsequently, the motor 52 is controlled to rotate. Motor 22 drives gear 23 to rotate, which in turn drives the upper mold 25 inside gear 24 to bend the pipe. At the same time, the upper mold 25 drives the belt 27 inside power wheel 26 to rotate, which in turn drives the threaded rod 31 at one end of power wheel 28 to rotate. Simultaneously, the threaded rod 31, limited by the limiting plate 34, causes the buckle 44 on the top surface of the moving frame 33 to move, thereby bending the pipe into a spiral shape. After bending is completed, the limiting plate 34 is removed, and the bent spiral pipe can then be taken out.

[0036] 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.
