Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a pipe fitting coiling device. Background Art

[0002] Since the production systems in the chemical and environmental protection fields are often under high temperature and high pressure conditions, it is mainly considered for the cold / hot heat exchange fluids with high temperature and high pressure on both sides. The pressure resistance requirements for containers and pipelines are relatively high, and the requirements for heat exchange efficiency are also relatively high. Therefore, it is advisable to choose a shell-and-tube heat exchanger for heat exchange of common materials in the chemical and environmental protection fields. However, common materials always contain a large amount of components such as organic matter, inorganic salts, and solid particles that are prone to scaling and deposition, resulting in the siltation and blockage of the heat exchanger pipelines, especially in areas where the flow rate decreases, such as the inner pipe elbow and the outer pipe connecting pipe. Therefore, a spiral coiling structure is usually applied to the shell-and-tube heat exchanger to make the solid-containing fluid flow from top to bottom, so as to facilitate the flow of solid particles in the heat exchange pipeline and reduce blockage. In the traditional spiral pipe fitting coiling device, it is difficult to fix the end of the pipe fitting during coiling, resulting in the pipe fitting being prone to sliding during the coiling process, thus affecting the coiling quality. Therefore, it is necessary to improve it. Summary of the Utility Model

[0003] Based on this, in view of the problem that the end of the pipe fitting is difficult to fix during coiling in the traditional spiral pipe fitting coiling device, resulting in the pipe fitting being prone to sliding during the coiling process, thus affecting the coiling quality, it is necessary to provide a pipe fitting coiling device.

[0013] In one embodiment, the pipe fitting between the positioning wheel and the clamping wheel is in the same plane as the second clamping groove, and the second clamping groove is parallel to the central axis of the support pipe.

[0014] In one embodiment, the rotating assembly includes a second motor and an adapter plate. The second motor is mounted on the first support member. The adapter plate is fixed to the output end of the second motor. A first clamping block is fixedly connected to the free end of the support pipe. A first clamping groove that is in interference fit with the first clamping block is formed at the free end of the adapter plate.

[0015] In one embodiment, a first groove that is in interference fit with the support pipe is formed at the free end of the adapter plate. A second clamping block is fixedly connected to the inner wall of the adapter plate.

[0018] For the above-mentioned pipe fitting coiling device, the bent portion of one end of the pipe fitting is bent by the elbow assembly, and then the bent end of the pipe fitting is clamped in the second clamping groove. By controlling the rotating assembly and the power member, the support pipe moves synchronously during rotation, so that the pipe fitting first bends along the guiding groove and then continuously spirally coils around the outer wall of the support pipe. After the processing is completed, the cylinder is controlled to separate the rotating assembly from the support pipe, which is convenient for taking out the processed pipe fitting.

[0032] The following is combined with Figures 1 - 5 to describe the pipe coiling device of the present invention.

[0033] As Figure 1 、 Figure 3 and Figure 4 shown, in one embodiment, a pipe coiling device includes a workbench 100, a pipe bending assembly 200, a support pipe 300, a cylinder 400, a rotating assembly 500 and a power member 600.

[0039] The power member 600 is installed on the workbench 100, and the power member 600 is used to drive the moving member 110 to move.

[0040] When the pipe fitting coiling device is in use, one end of the pipe fitting is bent by 90 degrees by the elbow component 200, and then the bent end of the pipe fitting is clamped in the second clamping groove 310. The rotating assembly 500 and the power member 600 are controlled to enable the support pipe 300 to move synchronously during rotation, so that the pipe fitting is first bent along the guide groove 340 and then continuously spirally wound around the outer wall of the support pipe 300. After the processing is completed, the air cylinder 400 is controlled to separate the rotating assembly 500 from the support pipe 300, so as to facilitate the removal of the processed pipe fitting. The operation is simple and convenient to use. By clamping the bent pipe fitting in the second clamping groove 310, the sliding phenomenon of the pipe fitting during the coiling process can be effectively prevented, and the coiling quality of the pipe fitting is improved.

The output end of the first motor 230 is fixedly connected to a third support member 240. A clamping wheel 250 is rotatably connected to the bottom of the third support member 240. A first clamping groove 260 is formed between the positioning wheel 210 and the clamping wheel 250.

[0042] In this embodiment, the rotating shaft of the third support member 240 is coaxial with the positioning wheel 210.

[0044] In use, by placing the pipe fitting in the first clamping groove 260, the first motor 230 is controlled to drive the third support member 240 to rotate. The third support member 240 drives the clamping wheel 250 to rotate 90 degrees around the positioning wheel 210, so as to bend one end of the pipe fitting by 90 degrees. Then, the bent pipe fitting is clamped in the second clamping groove 310.

[0045] Specifically, referring to Figure 3 and Figure 4 , the rotating assembly 500 includes a second motor 510 and an adapter plate 520.

Then, the second motor 510 is controlled to make the adapter plate 520 and the support pipe 300 rotate synchronously, thus facilitating the coiling process of the pipe fitting.

[0048] Specifically, referring to Figure 5 , the power member 600 includes a third motor 610, a lead screw 620, and a slider 630. The third motor 610 is installed on the workbench 100, the lead screw 620 is fixed to the output end of the third motor 610, the lead screw 620 passes through the slider 630, and the lead screw 620 is threadedly connected to the slider 630. The slider 630 is fixedly connected to the moving member 110, and a sliding groove 140 is provided on the surface of the workbench 100.

[0049] It should be added that bending portions 640 are symmetrically provided on the surface of the slider 630, and the area of the bottom end of the slider 630 is larger than that of its top end.
