Description

Technical Field

[0001] This utility model relates to the field of tube forming technology, specifically to a worm gear fine-tuning and locking mechanism for the forming angle of a spiral tube winding machine. Background Technology

[0002] Spiral pipe winding machine is a special equipment that processes metal pipes into spiral seam pipe products through continuous winding and other processes. It is widely used in the manufacturing of pipes in chemical, construction, water conservancy, municipal and other fields. Its working principle is to apply force to the metal pipe through clamping blocks, so that the pipe is wound into shape according to the preset spiral angle to form a spiral pipe with a certain length and diameter.

[0003] Existing spiral pipe winding machines mostly use a worm gear structure to adjust the angle of the forming component. The basic principle is to drive the worm to rotate, which in turn drives the meshing worm gear to rotate. The rotation of the worm gear changes the angle of the forming component, thereby adjusting the forming angle. However, this adjustment method is usually preset for pipe processing with a fixed diameter and cannot dynamically and in real time adjust the forming angle according to the actual size of the pipe being processed, which has limitations.

[0004] The inability to make targeted adjustments based on the size of the processed pipe will affect the quality of pipe forming. When processing pipes of different specifications, the fixed forming components are difficult to match the curling requirements of the pipe material, which can easily lead to problems such as pipe roundness deviation. Each time the processed pipe specifications are changed, the machine needs to be stopped for tedious manual adjustment and calibration, which prolongs the production preparation time and has limitations.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides, for example Figure 1 The worm gear fine-tuning and locking mechanism for the forming angle of a spiral tube winding machine shown includes a rotating drum 1. A fine-tuning and locking unit 2 is provided inside the rotating drum 1. The fine-tuning and locking unit 2 includes a flipping block 21, a clamping block 22 and an angle adjusting component 23. The flipping block 21 is located on one side of the rotating drum 1 and is rotatably connected to the rotating drum 1. The clamping block 22 is vertically slidably connected inside the flipping block 21. A fixing component is provided inside the flipping block 21. The fixing component is used to fix the clamping block 22 after the clamping block 22 is vertically adjusted. The angle adjusting component 23 is located inside the rotating drum 1 and is drivenly connected to the flipping block 21.

[0020] Example 1: In this example, when the device is in use, the clamping block 22 contacts the metal pipe to be processed. According to the diameter, wall thickness and other specifications of the pipe to be processed, the fixing bolt 28 can be loosened first, and the clamping block 22 can be pushed to slide vertically along the slot 24. The height of the clamping block 22 can be adjusted to match the position of the pipe. After the adjustment is completed, the fixing bolt 28 is tightened so that the end of the fixing bolt 28 abuts against the slot 25, thereby fixing the clamping block 22. At this time, the angle adjustment component 23 drives the flipping block 21 to rotate around the positioning block 29, thereby changing the contact angle between the clamping block 22 and the pipe, i.e. the forming angle, to match the current processing pipe's curling requirements. After adjustment, the angle adjustment component 23 can remain locked to ensure the forming angle is stable. The spiral pipe winding machine is composed of a push-pull cylinder, a rotary motor, and a rotating drum 1. Its principle is that after the pipe is clamped by the clamping block 22, the rotary motor starts and drives the rotating drum 1 to rotate. At the same time, the push-pull cylinder pushes the rotary motor to move to one side until all the pipes are wound on the rotating drum 1. At this time, the angle of the flipping block 21 is adjusted, and the pipe can be removed to complete the processing.

[0021] like Figures 2 to 3 The worm gear fine-tuning and locking mechanism for the forming angle of a spiral tube winding machine shown includes a rotating drum 1. A fine-tuning and locking unit 2 is provided inside the rotating drum 1. The fine-tuning and locking unit 2 includes a flipping block 21, a clamping block 22 and an angle adjusting component 23. The flipping block 21 is located on one side of the rotating drum 1 and is rotatably connected to the rotating drum 1. The clamping block 22 is vertically slidably connected inside the flipping block 21. A fixing component is provided inside the flipping block 21. The fixing component is used to fix the clamping block 22 after the clamping block 22 is vertically adjusted. The angle adjusting component 23 is located inside the rotating drum 1 and is drivenly connected to the flipping block 21.

[0022] The angle adjusting component 23 includes a drive motor 231 and a worm gear 232; the drive motor 231 is fixedly mounted inside the rotating drum 1; the worm gear 232 is rotatably connected inside the rotating drum 1, and the output shaft of the drive motor 231 is fixedly mounted to the worm gear 232. The angle adjusting component 23 also includes a worm wheel 233 and a support block 234; the worm wheel 233 is disposed on the worm gear 232, and the worm gear 232 meshes with the worm wheel 233; the support block 234 is fixedly mounted inside the rotating drum 1, and the worm wheel 233 is rotatably connected to the support block 234. The angle adjusting component 23 also includes a threaded rod 235, a rotating block 236, and a tilting groove 237; the threaded rod 235 is threadedly mounted inside the worm wheel 233; the rotating block 236 is disposed at the end of the threaded rod 235, and the rotating block 236 is rotatably connected to the threaded rod 235; the tilting groove 237 is formed inside the tilting block 21, and the rotating block 236 is rotatably connected to the inside of the tilting groove 237. The fastener includes a slot 24 and a block 25; the slot 24 is provided inside the flipping block 21, and the block 25 is fixedly mounted on the bottom of the clamping block 22, with the block 25 slidably connected inside the slot 24. The fastener also includes an anti-detachment groove 26 and an anti-detachment block 27; the anti-detachment groove 26 is provided inside the slot 24, and the anti-detachment blocks 27 are fixedly mounted on both sides of the block 25, with the anti-detachment blocks 27 slidably connected inside the anti-detachment groove 26. The fastener also includes a fixing bolt 28; the fixing bolt 28 is threaded inside the flipping block 21, and the end of the fixing bolt 28 abuts against the outer surface of the block 25. The fastener also includes a positioning block 29; the positioning block 29 is fixedly mounted on one side of the rotating cylinder 1, and the flipping block 21 is rotatably connected to the positioning block 29, with a positioning groove 210 provided inside the rotating cylinder 1.

[0023] Example 2: In this example, when the forming angle needs to be adjusted, the drive motor 231 is started. The output shaft of the drive motor 231 drives the worm 232 to rotate inside the rotating drum 1. The worm 232 meshes with the worm wheel 233, causing the worm wheel 233 to rotate synchronously under the support of the support block 234. Since the threaded rod 235 is threadedly engaged with the worm wheel 233, the rotational motion of the worm wheel 233 is converted into the axial linear motion of the threaded rod 235. The rotating block 236 at the end of the threaded rod 235 rotates in the flipping groove 237, while pushing or pulling the flipping block 21, causing the flipping block 21 to rotate around the positioning block 29, thereby precisely changing the forming angle. The worm wheel 233 and worm 232 transmission has a self-locking characteristic. After the drive motor 231 stops working, it can maintain the current angle position without deviation, realizing the stable locking of the forming angle.

[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
