Description

Technical Field

[0001] This invention relates to the field of resistance welding equipment technology, specifically to an adaptive control welding equipment for steel wire mesh skeletons used in polyethylene pipes. Background Technology

[0002] Steel wire mesh reinforced polyethylene composite pipes are widely used in municipal water supply, chemical fluid transportation, and mining pipelines due to their advantages such as high strength, corrosion resistance, crack resistance, and excellent pressure resistance. As the core load-bearing structure of the composite pipe, the weld strength and uniformity of the intersecting welds of the warp and weft wires directly determine the overall pressure resistance and service life of the pipe. Therefore, the welding quality of the steel wire mesh reinforcement is a key process in pipe production.

[0003] Existing resistance welding forming equipment for steel wire mesh skeletons generally adopts a welding structure of external pressure roller electrodes and an internal rigid conductive cylinder. The welding conductive circuit and clamping forming rely entirely on the unidirectional extrusion of the outer welding rollers. The internal support cylinder only serves to shape and fix the negative electrode conductivity. The surface of the cylinder is a fixed rigid structure and does not have adaptive elastic support or follow-up adjustment functions. In actual production, the longitudinal straight steel wires are prone to slight bending, warping, and springback deformation during the unwinding, winding, and tensioning processes. This causes the axial steel wires in some areas to fail to fully adhere to the outer wall of the internal rigid conductive cylinder, resulting in local suspension and excessive gaps. This leads to interruption of the welding negative electrode conductive path or significant fluctuations in contact resistance. Stable welding current cannot be obtained at the intersection points of the warp and weft steel wires, making it easy to have defects such as incomplete welding, missed welding, and insufficient weld fusion. This causes local detachment of the steel wire mesh skeleton, loosening of the structure, and seriously reduces the structural strength and yield of the pipe. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive control welding device for polyethylene pipes with steel wire mesh skeleton, which facilitates stable electrical conductivity of weld points, tight clamping, uniform welding quality, and improves the yield rate of pipe welding and the versatility of equipment, in order to solve the problems mentioned in the background art.

It includes a base 1, a support mechanism, and a welding mechanism. A support column 2 is fixedly connected to the upper side of the base 1. The support mechanism includes an elastic ring 3 mounted on the support column 2. The support mechanism controls the elastic ring 3 to slide along the outer wall of the support column 2 and lifts the middle part of the elastic ring 3, thereby providing outward support for the inner side of the axial steel wire 40. The welding mechanism includes a sliding frame 4 mounted on the upper side of the base 1. A conductive wheel 5 is provided on the sliding frame 4. The welding mechanism controls the sliding frame 4 and the elastic ring 3 to slide horizontally synchronously while simultaneously driving the conductive wheel 5 to rotate circumferentially around the support column 2, thus completing the circumferential rotation of the steel wire 40.

The side of the mounting ring 6 away from the elastic ring 3 is blade-shaped and slides against the outer wall of the support column 2.

The conductive post 18 set on the conductive rod 13 can maintain a contact state with the inner wall of the elastic ring 3 under the push of the first elastic element 17, and help push out the middle of the elastic ring 3. It provides elastic support for some positions where the axial steel wire 40 is bent and cannot fit tightly, and maintains the contact state.

[0020] Example 2: Please refer to Figures 1-6This embodiment further illustrates Embodiment 1. The welding mechanism shown in the figure also includes a rotating ring 20 rotatably connected to the side of the sliding frame 4. A second sliding groove 21 is provided on the base 1. The sliding frame 4 is slidably connected to the inner wall of the second sliding groove 21 in the horizontal direction. A threaded rod 22 is rotatably connected to the base 1. The threaded rod 22 passes through the sliding frame 4 and is threadedly connected to the inner wall of the sliding frame 4. The base 1 is provided with a driving component for synchronously driving the conductive column 18, the threaded rod 22, and the rotating ring 20 to rotate. The rotating ring 20 is provided with an auxiliary component for conducting electricity and feeding wire to the conductive wheel 5. The driving component includes a drive motor 23 fixedly installed on the base 1. The drive motor 23 is of type... The preferred type is Y80M1-2. The drive motor 23 drives the threaded rod 22 to rotate. Multiple control grooves 24 are evenly distributed axially on the outer wall of the threaded rod 22. A gear ring 25 is rotatably connected to the side of the sliding frame 4. Multiple control blocks 26 are evenly fixedly connected to the inner wall of the gear ring 25 and slidably connected horizontally to the inner wall of the control grooves 24. An external gear ring 27 that meshes with the gear ring 25 is fixedly connected to the outer wall of the rotating ring 20. A transmission component is provided on the conductive post 18 to drive the conductive post 18 to rotate when the threaded rod 22 rotates. Auxiliary components include a wire feeding device 28 fixedly installed on the rotating ring 20. A [missing information - likely a device name or component] is fixedly connected to the rotating ring 20. A fixed frame 29 has a conductive frame 30 slidably connected inside it. A conductive wheel 5 is rotatably connected to the conductive frame 30. A second elastic element 31, which is fixedly connected to the inner wall of the fixed frame 29, is fixedly connected to the conductive frame 30. The transmission component includes a driving wheel 32 coaxially fixedly mounted on a threaded rod 22. A driven wheel 33 is coaxially fixedly connected to one end of a conductive post 18. A transmission belt 34 drives the driving wheel 32 and the driven wheel 33. The conductive wheel 5 is connected to the positive terminal of the power supply through the conductive frame 30 and the fixed frame 29. The conductive post 18 is connected to the negative terminal of the power supply. The control block 26 is driven to rotate through the control groove 24 on the threaded rod 22. The control block 26 drives the gear ring 25 to rotate. The gear ring 25 drives the external gear ring 27 to rotate the rotating ring 20. The rotating ring 20 drives the wire feeding device 28 and the fixed frame 29 to rotate synchronously. The wire feeding device 28 continuously feeds the circumferential steel wire 41 to the conductive wheel 5. Guided by the groove in the middle of the conductive wheel 5, the circumferential steel wire 41 is stably fed to the outside of the axial steel wire 40. The second elastic element 31 pushes the conductive frame 30, so that the side of the conductive wheel 5 always pushes the circumferential steel wire 41 to stick tightly to the outside of the axial steel wire 40. With the outward push of the elastic ring 3 at the same position inside, the circumferential steel wire 41 and the axial steel wire 40 can be tightly fitted between the conductive wheel 5 and the elastic ring 3.

[0021] Example 3: Please refer to Figures 1-3This embodiment further illustrates Embodiment 1. In the figure, a support plate 35 is slidably connected to the base 1 along the vertical direction. The support plate 35 supports the bottom of the support column 2 on the side away from the drive motor 23. The outer wall of the support column 2 can rotate in contact with the upper side of the support plate 35. A push block 36 is fixedly connected to the bottom of the support plate 35. An electric telescopic rod 37 is fixedly connected to the base 1. A trapezoidal block 38 is fixedly connected to the telescopic end of the electric telescopic rod 37. The side of the push block 36 is provided with a slope 39 that can slide in contact with the inclined surface of the trapezoidal block 38. Activate the electric telescopic rod 37 to push the trapezoidal block 38 to slide towards the pushing block 36. The inclined surface of the trapezoidal block 38 abuts against the slope 39, thereby lifting the pushing block 36. The pushing block 36 drives the support plate 35 to move upward together, so that the upper end of the support plate 35 can support the bottom outer wall of the support column 2. When it is necessary to remove the wire mesh skeleton, control the electric telescopic rod 37 to retract, so that the trapezoidal block 38 releases its support from the pushing block 36, and the support plate 35 moves downward. At this time, the welded wire mesh skeleton can be removed from one end of the support column 2.

[0022] Working principle: Multiple sets of axial steel wires 40 are evenly arranged and their two ends are fixed to the fixing parts on the outside of the support column 2. The electric telescopic rod 37 is activated to push the trapezoidal block 38 to slide towards the pushing block 36. The inclined surface of the trapezoidal block 38 abuts against the slope 39, thereby lifting the pushing block 36. The pushing block 36 drives the support plate 35 to move upward together, so that the upper end of the support plate 35 can support the bottom outer wall of the support column 2. The drive motor 23 drives the threaded rod 22 to rotate. The threaded rod 22 drives the sliding frame 4 to slide along the second sliding groove 21 from one end near the support plate 35 to the other end. At the same time, the drive wheel 32 drives the transmission belt 34 to make the driven wheel 33 and the conductive column 18 rotate. The conductive column 18 drives the drive column 8 to slide horizontally synchronously along the drive groove 7 through the threaded groove 19, ensuring that the horizontal sliding speed of the drive column 8 is the same as the sliding speed of the sliding frame 4.

[0023] The axial steel wire 40 is supported outward by the central part of the internal elastic ring 3. The surfaces of the mounting rings 6 on both sides of the elastic ring 3 have a certain slope, which can smoothly scoop the axial steel wire 40 onto the top of the elastic ring 3. The axial steel wire 40 is supported by the raised part in the middle of the elastic ring 3. In addition, multiple sets of tension springs 14 are set on both sides of the conductive rod 13, which can pull the connecting rod 11 and the mounting ring 6 towards one side of the elastic ring 3, so that the elastic ring 3 can always maintain an outward raised state. The conductive block 15 set on the conductive rod 13 can be connected to the first elastic element 1. Under the push of 7, it remains in contact with the inner wall of the elastic ring 3, assisting in pushing out the middle of the elastic ring 3. This allows the elastic ring 3 to be flattened due to being tightly pressed against the axial steel wire 40 in some positions, while other areas can still maintain a local convex state under the push of the conductive block 15. It provides elastic support for some positions where the axial steel wire 40 is bent and cannot be tightly pressed, maintaining the contact state. The elastic ring 3 is made of a metal material with excellent conductivity and resilience, and can rebound to its initial state when the contact state with the axial steel wire 40 is released.

[0024] The control block 26 rotates via the control groove 24 on the threaded rod 22, which in turn rotates the gear ring 25. The gear ring 25 then rotates the external gear ring 27, causing the rotating ring 20 to rotate. The rotating ring 20 drives the wire feeding device 28 and the fixed frame 29 to rotate synchronously. The wire feeding device 28 continuously feeds the circumferential wire 41 onto the conductive wheel 5. Guided by the groove in the middle of the conductive wheel 5, the circumferential wire 41 is stably fed to the outside of the axial wire 40. The second elastic element 31 pushes the conductive frame 30, ensuring that the side of the conductive wheel 5 always pushes the circumferential wire 41 tightly against the outside of the axial wire 40. Combined with the outward push of the elastic ring 3 at the same internal position, the circumferential wire 41 and the axial wire 40 are able to move between the conductive wheel 5 and the elastic ring. The components 3 are tightly fitted together. The conductive wheel 5 is connected to the positive terminal of the power supply through the sliding frame 4, rotating ring 20, fixed frame 29 and conductive frame 30. The elastic ring 3 is connected to the negative terminal of the power supply through the conductive column 18 and conductive block 15. This generates current between the conductive wheel 5 and the elastic ring 3, and generates high temperature at the joint between the circumferential steel wire 41 and the axial steel wire 40, melting and connecting the steel wires to complete the resistance welding operation. When it is necessary to remove the steel wire mesh skeleton, the electric telescopic rod 37 is retracted, which allows the trapezoidal block 38 to contact the support of the pushing block 36, and the support plate 35 moves down. At this time, the welded steel wire mesh skeleton can be removed from one end of the support column 2. The first elastic element 17 and the second elastic element 31 can be replaced by any existing elastic structure such as a spring.
