Description

Technical Field

[0001] The utility model mainly relates to the technical field of steel wire mesh skeleton pipes, and particularly relates to a welding device for steel wire mesh skeleton pipes. Background Technique

[0002] The steel wire mesh skeleton pipe is an industry abbreviation for the steel wire mesh skeleton plastic composite pipe, which is an improved new type of steel skeleton plastic composite pipe. This kind of pipe is made by cross-weaving high-strength steel wires after plastic coating into a mesh as the skeleton and fusing with thermoplastic polyethylene. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe, and high-density polyethylene is used as the core pipe matrix. A high-performance polyethylene modified bonding resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, making it have excellent composite effects. Because the high-strength steel wire reinforcement is coated in the continuous thermoplastic plastic, this composite pipe overcomes the respective disadvantages of steel pipes and plastic pipes while maintaining the respective advantages of steel pipes and plastic pipes.

[0003] For example, Chinese Patent Publication No. CN216178066U discloses a welding docking frame for steel wire mesh skeleton pipes, which relates to the technical field of pipe welding, including a support device and a welding device. The top of the support device is fixedly connected to the bottom of the welding device. The support device includes a welding machine, a base, and a first support rod. The welding device includes a bottom plate and a fixing ring.

[0004] Through the above application, by setting the welding device, the skeleton pipe is placed in the semi-circular ring, and then the docking pipe is placed in the fixing ring. The moving plate is pushed to fix the docking pipe to prevent the docking pipe from shaking during welding. The fixing ring and both ends are concentric circles to ensure that the skeleton pipe can be welded normally, which is convenient for the operator during welding. However, the welding torch in the steel wire mesh skeleton pipe welding device cannot adjust the height and position, and the fixture cannot rotate automatically. During the welding process, the angle and height of the welding torch need to be precisely controlled to ensure the fusion quality of the weld. The non-adjustable welding torch may cause defects such as incomplete penetration and slag inclusion in the weld, affecting the welding quality. When welding the steel wire mesh skeleton pipe, if the fixture cannot rotate automatically, manual rotation is required, which will increase the labor intensity of workers and reduce the welding efficiency.

[0031] Referring to the attached Figures 1 to 6 , a welding device for a steel wire mesh skeleton pipe, includes a horizontally arranged workbench 1, a mounting frame 2 vertically arranged on the workbench 1, and a rotary fixture 5 arranged on the workbench 1. The rotary fixture 5 is used for clamping and fixing two skeleton pipes 6 to be welded and driving the skeleton pipes 6 to rotate;

[0032] A telescopic rod 3 is vertically arranged on the mounting bracket 2. An adjusting mechanism 4 is arranged on the output end of the telescopic rod 3, and a welding torch 7 is arranged on the output end of the adjusting mechanism 4. The telescopic rod 3 is used to adjust the position of the welding torch 7, and the adjusting mechanism 4 is used to adjust the height of the welding torch 7.

[0033] The adjusting mechanism 4 includes a connecting block 41 fixedly connected to the output end of the telescopic rod 3. An installation plate 42 is fixedly installed on the connecting block 41. An electric push rod 43 is fixedly installed on the installation plate 42. An installation rod 47 is arranged on the output end of the electric push rod 43. A movable clamping block 48 is movably arranged on the installation rod 47. A welding torch mounting seat 49 for mounting the welding torch 7 is arranged on the movable clamping block 48.

[0034] An installation block 46 is fixedly arranged on the output end of the electric push rod 43. The installation rod 47 is fixed on the installation block 46. A slider 44 is fixedly arranged at one end of the installation block 46 away from the installation rod 47. A guide rail 45 is fixedly installed on the installation plate 42. The slider 44 is slidably installed on the guide rail 45.

[0035] A threaded sleeve 410 is arranged at the top end of the installation rod 47. A screw rod 411 is installed in the threaded sleeve 410 by thread. One end of the screw rod 411 is an adjusting knob 412. A threaded block 413 is arranged on the movable clamping block 48. The threaded block 413 is connected to the screw rod 411 by thread.

[0036] The rotary fixture 5 includes a plurality of bearing seats 57 arranged on the workbench 1. A driving rotating shaft 56 and a driven rotating shaft 59 are respectively rotatably installed in the bearing seats 57. The driving rotating shaft 56 and the driven rotating shaft 59 are concentrically arranged. Clamping chucks 58 are symmetrically arranged at adjacent ends of the driving rotating shaft 56 and the driven rotating shaft 59. The clamping chucks 58 are used to clamp and fix the skeleton tube 6 to be welded.

[0037] One end of the driving rotating shaft 56 away from the clamping chuck 58 is fixed on a connecting disc 55. The connecting disc 55 is connected to a driving mechanism. The driving mechanism includes an installation box 51 and a vertical plate 52. A motor 53 is fixedly installed on the vertical plate 52. The output end of the motor 53 is connected to the connecting disc 55 through a synchronous belt assembly 54.

[0038] Working principle:

[0039] The position adjustment of the welding torch 7 in the vertical direction can be achieved through the electric push rod 43. The cooperation between the slider 44 and the guide rail 45 can ensure the stability and linearity of the output end of the electric push rod 43 during the movement. In addition, the position adjustment of the movable clamping block 48 can be realized through the cooperation of the screw 411, the threaded sleeve 410 and the threaded block 413, so as to further finely adjust the position of the welding torch 7. In addition, by rotating the movable clamping block 48, the angle of the movable clamping block 48 on the mounting rod 47 can be adjusted, so that the inclination angle of the welding torch 7 can be adjusted. This multi-degree-of-freedom adjustment method can achieve high-precision adjustment of the position of the welding torch 7 to meet the needs of different welding processes and requirements.

[0040] The skeleton tube 6 to be welded can be firmly clamped by the chuck 58, ensuring that the skeleton tube 6 will not move or shake during the welding process. The clamping range of the chuck 58 can be adjusted according to the skeleton tubes 6 with different pipe diameters, showing strong adaptability. The motor 53 drives the connecting disk 55 to rotate through the synchronous belt assembly 54, and then drives the active rotating shaft 56 to rotate. Since the active rotating shaft 56 and the driven rotating shaft 59 are concentrically arranged and the chucks 58 at the adjacent ends clamp the skeleton tube 6, the rotation of the skeleton tube can be realized for all-round welding. The setting of multiple bearing seats 57 provides stable support for the active rotating shaft 56 and the driven rotating shaft 59, ensuring the smoothness of the rotation process and helping to improve the welding quality. The active rotating shaft 56 and the driven rotating shaft 59 are concentrically arranged, enabling the clamped skeleton tube 6 to maintain good concentricity, which is beneficial to ensuring the welding precision and quality. The automatic rotation is realized through the motor 53 and the synchronous belt assembly 54, reducing manual operation, improving work efficiency and reducing labor intensity.

[0041] By rotating the fixture 5, two skeleton tubes 6 to be welded can be clamped and fixed, and driven to rotate, so that the welding can be carried out in the circumferential direction of the tube, ensuring the integrity and uniformity of the welding. The telescopic rod 3 can adjust the position of the welding torch 7 in the horizontal direction, so that the welding torch 7 can be aligned with the part to be welded. The adjusting mechanism 4 can adjust the height of the welding torch 7 in the vertical direction to adapt to the changes in different pipe diameters and welding requirements.

[0042] The above-described embodiments only represent a certain implementation manner of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
