Description

Technical Field

[0001] The utility model relates to the technical field of capacitor welding, in particular to a capacitor welding device for PE pipes used for water supply. Background Art

[0002] Water supply refers to the activity or process of transporting water from a water source to a user through pipes or other facilities. PE pipes refer to pipes made of polyethylene (PE) used in water supply systems. PE pipes are widely used in water supply systems. Their main features include corrosion resistance, pressure resistance, wear resistance, and easy installation. Therefore, they are widely recognized and used. In order to complete the connection of pipes in a shorter time, this is very important for large-scale water supply projects, so capacitor welding devices are required.

[0003] In the process of using traditional PE pipe capacitor welding, when installing and fixing the PE pipe, the PE pipe is moved between the fixed frame and the movable frame, and then the first hydraulic cylinder is operated to push the connecting rod downward, and the connecting rod drives the movable frame to gradually approach the fixed frame. The clamping rings on the inner side of the fixed frame and the movable frame cooperate with each other, so that the PE pipe can be automatically fixed, avoiding repeated rotation of the bolts during the fixing process, thereby improving the fixing efficiency of the PE pipe and facilitating hot-melt welding of the PE pipe.

[0004] However, since PE pipes are generally long and there is only one direct rack on both sides, the rear of the pipe has no support and is easy to bend, and there is no positioning structure, which makes it easy to misalign during docking and fixation, causing deviations in the pipeline and affecting the quality of the water supply project.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a capacitor welding device for PE pipes for water supply, comprising a base 1, a transmission assembly is arranged inside the base 1, a slider 4 is slidably connected inside the base 1, a support plate 5 is fixedly connected to the top of the slider 4, a limiting frame 6 and a fixing ring 7 are fixedly connected to the top of the support plate 5, a limiting ring 8 is rotatably connected inside the fixing ring 7, a connecting block 9 is rotatably connected to the outer wall of the limiting ring 8, a sleeve 26 is rotatably connected to the outer wall of the limiting ring 8, a positioning arm 10 is rotatably connected to the outer wall of the fixing ring 7, the outer wall of the positioning arm 10 is penetrated inside the sleeve 26, one end of the positioning arm 10 is rotatably connected to a positioning wheel 14, the outer wall of the fixing ring 7 is rotatably connected to a connecting block 2 11, and one side of the connecting block 2 11 is fixed A motor 2 12 is fixedly connected, a transmission threaded rod 13 is fixedly connected to the output end of the motor 2 12, the outer wall of the transmission threaded rod 13 is threadedly connected to the inside of the connecting block 1 9, a first telescopic rod 15 is fixedly connected to the inside of the limiting frame 6, one end of the first telescopic rod 15 is fixedly connected to a clamping piece 16, and a first spring 17 is sleeved on the outer wall of the first telescopic rod 15. The transmission assembly includes a motor 1 2 and a bidirectional threaded rod 3, one side of the motor 1 2 is fixedly connected to one side of the base 1, one end of the bidirectional threaded rod 3 is fixedly connected to the output end of the motor 1 2, the outer wall of the bidirectional threaded rod 3 is threadedly connected to the inside of the slider 1 4, one end of the first spring 17 is fixedly connected to the bottom of the clamping piece 16, and the other end of the first spring 17 is fixedly connected to the inside of the limiting frame 6;

[0033] Specifically, first, we pass the pipe to be welded through the inside of the limit frame 6. The first spring 17 is designed inside the limit frame 6, which provides a stable support for the clamping piece 16. This design ensures that the clamping piece 16 can tightly fix the pipe, avoiding the problem of reduced welding quality due to the movement of the pipe during the welding process. Next, the pipe continues to pass through the inside of the fixing ring 7. At this time, the motor 2 12 starts to work, and its output end drives the transmission threaded rod 13 to rotate rapidly. The rotation of the transmission threaded rod 13 drives the rotation of the limit ring 8 through the connecting block 1 9. The rotation of the limit ring 8 further drives the rotation of the sleeve 26. It is worth mentioning that one end of the positioning arm 10 rotates flexibly on the fixing ring 7, so when the sleeve 26 rotates, it drives the positioning arm 10 to close, thereby accurately positioning and clamping the pipe. This design ensures the stability and accuracy of the pipe during the welding process. Finally, the output end of the motor 1 2 starts to work, driving the bidirectional threaded rod 3 to rotate slowly. The rotation of the bidirectional threaded rod 3 drives the closing of the support plate 5 through the slider 1 4. This step further ensures the stability and fixation of the pipe during the welding process.

[0034] Reference Figure 4 and Figure 5 A slide groove 18 is provided inside the base 1, a rack 19 is fixedly connected inside the base 1, a slider 20 is provided inside the base 1, the outer wall of the slider 20 is slidably connected inside the slide groove 18, a welding head 21 is fixedly connected to the top of the slider 20, a symmetrically arranged limit plate 22 is slidably connected inside the slider 20, a clamping block 23 is fixedly connected to one side of the limit plate 22, a second telescopic rod 24 is provided inside the slider 20, a second spring 25 is sleeved on the outer wall of the second telescopic rod 24, and both ends of the second telescopic rod 24 and the second spring 25 are fixedly connected between the limit plate 22;

[0035] Specifically, when the output end of the motor 1 2 starts to rotate, the bidirectional threaded rod 3 rotates accordingly, and drives the support plate 5 to close through the slider 1 4. The pipes on both sides are in close contact and accurately positioned under the welding head 21. At the moment when the pipe contacts the welding head 21, the high temperature causes the contact part of the pipe to melt rapidly. Under the action of the welding head 21, the molten pipe is perfectly integrated into one, which not only ensures the firmness of the connection, but also ensures the overall beauty of the pipe. Subsequently, the output end of the motor 1 2 is reversed, and this subtle change allows the pipe and the welding head 21 to be easily separated. Driven by the motor, the separated welding head 21 quickly moves to one side to prepare for the next welding. Immediately afterwards, the output end of the motor 1 2 rotates forward again, driving the pipes at both ends to close, and the melted pipes are tightly spliced ​​together. In this process, the welding head 21 slides inside the slide 18 through the slider 2 20, achieving precise limit. At the same time, the block 23 in the slider 20 is cleverly embedded in the rack 19, providing stable positioning for the welding head 21. In order to ensure that the block 23 does not easily slide out of the rack 19, the limiting plate 22 and the second spring 25 work together. The limiting plate 22 limits the block 23 in the slider 20, and the second spring 25 supports the block 23 with its tension to ensure that the block 23 is always tightly embedded in the rack 19. This precise design not only effectively prevents the welding head 21 from moving at will, but also greatly improves the accuracy and stability of pipe welding.

[0036] Working principle: When using the capacitor welding device for PE pipes for water supply, first, the pipe to be welded is passed through the inside of the limit frame 6, and the clamping piece 16 is supported by the first spring 17 in the limit frame 6, so that the clamping piece 16 fixes the pipe, and then the pipe passes through the inside of the fixing ring 7, and at the same time, the output end of the motor 2 12 drives the transmission threaded rod 13 to rotate, and when the transmission threaded rod 13 rotates, it drives the limit ring 8 to rotate through the connecting block 1 9, and when the limit ring 8 rotates, it drives the sleeve 26 to rotate, and one end of the positioning arm 10 rotates on the fixing ring 7, so the sleeve 26 will drive the positioning arm 10 to close to position and clamp the pipe, and then the output end of the motor 2 drives the bidirectional threaded rod 3 to rotate, and the bidirectional threaded rod 3 The support plate 5 is driven to close by the slider 4, so that the pipes on both sides contact the welding head 21 to melt, and then the output end of the motor 2 is reversed to separate the pipe from the welding head 21, and then the welding head 21 is pushed to one side, and the output end of the motor 2 rotates forward to drive the pipes at both ends to close and splice the pipes together. The welding head 21 is limited by sliding in the slide groove 18 through the slider 2 20, and is positioned by the block 23 in the slider 20 being engaged in the rack 19. The block 23 is limited in the slider 20 by the limiting plate 22, and is supported by the tension of the second spring 25, so that the block 23 is embedded in the rack 19 and is not easy to slide out, thereby fixing the welding head 21 to prevent the welding head 21 from moving at will.
