Description

Technical Field

[0001] The utility model relates to the technical field of coil winding tools, in particular to a heat exchanger coil winding device. Background Art

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used. Coil is an important heat exchange component of heat exchanger. Through special bending, the flow distance of heat exchange medium in heat exchanger is increased, thereby increasing heat exchange efficiency.

[0003] At present, when heat exchangers are produced in large quantities, special pipe bending machines are generally purchased to process coils. However, in order to reduce production and procurement costs during the trial stage of new models or small-batch processing, a simple coil winding tool is generally made for winding. The existing coil winding tooling relies on manpower for winding. There are the following problems with manual winding: 1. The force applied to the coil by humans is uneven. Since the wall of the coil is thin, it is easy to break the wall when bending under uneven force, which leads to the scrapping of the entire coil. Therefore, the winding quality of the coil cannot be guaranteed; 2. Manual coil winding is labor-intensive, and the winding efficiency is affected as physical strength is consumed.

[0004] Therefore, there is an urgent need for a heat exchanger coil winding device to improve the coil winding efficiency and ensure the winding quality. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a heat exchanger coil winding device, which is used to solve the problem that the existing coil winding tooling cannot ensure the coil winding quality and has low winding efficiency through manual winding.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0015] In summary, the beneficial technical effects of the utility model are:

[0016] (1) The use of a drive motor and a reducer instead of manpower to provide power for the winding mechanism not only reduces the labor intensity of manual winding, but also ensures uniform force during winding, preventing the wall of the coil from breaking during winding.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] See attached Figure 1-4 , shown is a heat exchanger coil winding device, including a workbench 1 and a frame 2, wherein a guide assembly is provided on the workbench 1, and the guide assembly includes a U-shaped bracket 22, and a first guide wheel 23 and a second guide wheel 24 are provided in the U-shaped bracket 22 to rotate from bottom to top in sequence, and the pipe fitting is placed between the first guide wheel 23 and the second guide wheel 24 during coil winding, and the first guide wheel 23 and the second guide wheel 24 are clamped to limit the pipe fitting up and down, and at the same time, the bottom of the U-shaped bracket 22 is rotatably connected to the workbench 1 through a rotating shaft, so that the pipe fitting can swing along with the change of the winding position when moving, and the stress on the pipe fitting can be released in time;

[0028] A driving motor 4 is provided at the bottom of the frame 2, and a mounting seat 3 is fixedly provided at the top of the frame 2, a reducer 5 is fixedly provided on the mounting seat 3, the reducer 5 is linked with the output end of the driving motor 4 through a driving belt 6, two bearings 7 are arranged side by side along the output end of the reducer 5 of the mounting seat 3, a rotating rod 8 is rotatably provided in the two bearings 7, the rotating rod 8 includes an optical axis 16 and a lead screw 17, wherein the optical axis 16 is placed in the bearing 7 and connected to the reducer 5, a winding mechanism is provided on the lead screw 17, and the winding mechanism includes a first chuck 9 and a second chuck 10 which are parallelly mounted on the lead screw 17, and a winding mechanism is fixedly provided on one side of the first chuck 9 The winding wheel 11 is provided with a chuck 18 on the side of the winding wheel 11 away from the first chuck 9. The chuck 18 is provided with a plurality of teeth 19 on the circumference. The second chuck 10 is provided with a set ring 20 at a position corresponding to the chuck 18.
