Description

Technical Field

[0001] This utility model relates to the field of water pipe construction technology, and more specifically, to a welding device for water pipe construction. Background Technology

[0002] Water pipes are widely used in building water supply and drainage, but they often do not have auxiliary docking structures at both ends. Therefore, during the construction of building water supply and drainage, welding is required for connection. For example, the quick-connection welding device for PE water supply pipes proposed in application number "CN202310958940.0" includes a PE pipe and a movable base. A movable frame is uniformly fixedly connected to one side of the top of the movable base, and a fixed frame is uniformly slidably connected to the other side of the top of the movable base. Clamping rings are provided on the side walls of both the fixed frame and the movable frame. A drive motor is fixedly connected to the side of the movable base near the movable frame. A sleeve penetrating the movable frame is fixedly connected to the output end of the drive motor. A sleeve rod is slidably connected inside the sleeve.

[0003] However, in the above technical solution, the device only fixes the water pipe by clamping ring and lacks a pre-treatment structure for the water pipe end. If there are burrs or unevenness at the water pipe end, direct welding will result in an excessively large gap between the joints, affecting the sealing performance of the weld and making it prone to leakage later. Therefore, we propose a welding device for water pipe construction to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) In this utility model, a rotating ring with a blade is set inside the front support frame of the welding mechanism. With the help of the gear and gear ring transmission structure driven by the motor, the blade can be driven to rotate and cut around the water pipe port. This design can quickly remove the burrs of the water pipe port and flatten the port cut surface, ensuring that the two water pipe ports fit tightly together during subsequent welding. This reduces the gap at the source, effectively avoids the risk of water leakage due to poor sealing in the later stage, and significantly improves the welding quality and the stability of the pipeline.

[0014] (2) The present invention adopts a hinged connection structure of lower clamping frame and upper clamping frame, and strengthens the fixing effect by a locking component composed of first groove, second groove, second movable block and positioning rod. When in use, the water pipe is first placed in the lower clamping frame, and after the upper clamping frame is closed, the second movable block is slid to make it clamp between the upper and lower grooves, and then the position is locked by the positioning rod. It can form an all-round wrapping fixation for the water pipe. Compared with a single clamping ring, the fixation is more firm and less prone to displacement, providing stable support for port pretreatment and welding process, and further ensuring construction accuracy.

[0027] First, place the two raw materials 5 to be welded into the lower clamping frame 7 at the upper end of the fixing block 3 and the lower clamping frame 7 at the upper end of the slider 4, respectively. Then, rotate the upper clamping frame 8 around the hinge so that the upper clamping frame 8 and the lower clamping frame 7 together wrap around the water pipe. Then, rotate the second movable block 11 along the second fixing rod 10 so that it simultaneously engages in the first groove 9 of the upper clamping frame 8 and the second groove 12 of the lower clamping frame 7. At the same time, move the positioning rod 13 to the lower end of the lower clamping frame 7 to limit the second movable block 11, thus fixing the raw materials 5. Then, push the first movable block 601 on the front side of the welding mechanism 6 so that it moves along the guide rod 2 to close to Position the raw material port 5, then grasp the first handle 606 of the front support frame 604, rotate the support frame 604 around the first fixed rod 603 in the first movable groove 602, adjust it until the blade 613 on the inner wall of the rotating ring 607 is in contact with the raw material port 5, then start the motor 612 on one side of the front support frame 604. The output end of the motor 612 drives the first gear 611 in the second movable groove 609 to rotate. The first gear 611 meshes with the gear ring 608 on the outer side of the rotating ring 607, causing the rotating ring 607 to rotate in the annular slide groove 610, thereby driving the blade 613 to rotate and cut around the raw material port 5, removing... Deburr and smooth the cut surface at the port, then turn off the motor 612, rotate the front support frame 604 in the opposite direction to move the blade 613 away from the water pipe port, then push the first movable block 601 on the front side to move away along the guide rod 2, and then push the first movable block 601 on the rear side of the welding mechanism 6 to move it along the guide rod 2 to the position between the two water pipe ports. Hold the first handle 606 of the rear support frame 604, rotate the support frame 604 around the first fixed rod 603 in the first movable groove 602, adjust the heating plate 605 inside the support frame 604 to be aligned and close to the two water pipe ports, and then start the heating plate 605. 05 Heat the ends of the two raw materials 5. After heating to the preset welding temperature, turn off the heating plate 605, rotate the rear support frame 604 in the opposite direction and push the first movable block 601 on the rear side to move away along the guide rod 2. Then, the user rotates the second handle 19 at the front end of the slider 4, which drives the rotating rod 17 in the third movable groove 16 to rotate. The second gear 18 on the outside of the rotating rod 17 meshes with the rack 15 in the guide rod 2 placement groove 14, so that the slider 4 moves along the guide rod 2 towards the fixed block 3 until the ends of the two raw materials 5 are pressed together. Keep them pressed together until the weld cools and solidifies, thus completing the welding of the raw materials 5.

[0028] The first movable block 601 can slide along the guide rod 2, and can flexibly adjust the pre-treatment position according to the length of the raw material 5, adapting to the port processing requirements of raw materials 5 of different specifications, and improving the versatility of the device. The support frame 604 rotates in the first movable groove 602 through the first fixed rod 603, which can precisely control the contact angle and force between the blade 613 and the port of the raw material 5, ensuring that the blade 613 always maintains stable contact with the port during cutting, and ensuring a flat cut surface. The structure of the first gear 611 and the gear ring 608 driven by the motor 612 can drive the rotating ring 607 to rotate at a constant speed in the annular slide groove 610, so that the blade 613 cuts evenly around the port, avoiding the problem of uneven cut surface caused by manual cutting, reducing weld gaps from the root, and reducing the risk of water leakage.

[0029] The transmission structure consisting of the second handle 19, the rotating rod 17, the second gear 18, and the rack 15 can achieve smooth movement of the slider 4 by manual rotation, making operation simpler and more intuitive. It can also precisely control the docking speed and force of the raw material 5, avoiding port misalignment caused by excessive docking speed and ensuring alignment accuracy. The design of the slider 4 moving along the guide rod 2 ensures that the slider 4 drives the raw material 5 to always move along a straight line close to the side of the fixed block 3, further improving alignment accuracy, ensuring coaxiality at the weld, and enhancing the stability of the raw material 5 in subsequent use.

[0030] The working principle of a welding device for water pipe construction:

[0031] In use, firstly, place the two raw materials 5 to be welded into the lower clamping frame 7 at the upper end of the fixing block 3 and the lower clamping frame 7 at the upper end of the slider 4, respectively. Then, rotate the upper clamping frame 8 around the hinge so that the upper clamping frame 8 and the lower clamping frame 7 together wrap around the water pipe. Then, rotate the second movable block 11 along the second fixing rod 10 so that it simultaneously engages in the first groove 9 of the upper clamping frame 8 and the second groove 12 of the lower clamping frame 7. At the same time, move the positioning rod 13 to the lower end of the lower clamping frame 7 to limit the second movable block 11, thus fixing the raw materials 5. Then, push the first movable block 601 on the front side of the welding mechanism 6 so that it moves along the guide rod 2. Move the device close to the raw material port 5, then grasp the first handle 606 of the front support frame 604 and rotate the support frame 604 around the first fixed rod 603 in the first movable groove 602. Adjust the blade 613 on the inner wall of the rotating ring 607 to fit against the raw material port 5. Then start the motor 612 on one side of the front support frame 604. The output end of the motor 612 drives the first gear 611 in the second movable groove 609 to rotate. The first gear 611 meshes with the gear ring 608 on the outer side of the rotating ring 607, causing the rotating ring 607 to rotate in the annular groove 610, thereby driving the blade 613 to rotate and cut around the raw material port 5. Remove burrs from the port and smooth the cut surface. Then turn off the motor 612, rotate the front support frame 604 in the reverse direction to move the blade 613 away from the water pipe port, and push the first movable block 601 on the front side to move away along the guide rod 2. Then push the first movable block 601 on the rear side of the welding mechanism 6 to move it along the guide rod 2 to the position between the two water pipe ports. Hold the first handle 606 of the rear support frame 604 and rotate the support frame 604 around the first fixed rod 603 in the first movable groove 602 to adjust the heating plate 605 inside the support frame 604 to be aligned and close to the two water pipe ports. Then start the heating plate. Heating plate 605 heats the ends of the two raw materials 5. After heating to the preset welding temperature, heating plate 605 is turned off. The rear support frame 604 is rotated in the opposite direction and the first movable block 601 on the rear side is pushed away along the guide rod 2. Then, the user rotates the second handle 19 at the front end of the slider 4, which drives the rotating rod 17 in the third movable groove 16 to rotate. The second gear 18 on the outside of the rotating rod 17 meshes with the rack 15 in the guide rod 2 placement groove 14, so that the slider 4 moves along the guide rod 2 towards the fixed block 3 until the ends of the two raw materials 5 are put together after heating. The put together state is maintained until the welding point cools and solidifies, thus completing the welding of the raw materials 5.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here.
