[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] The utility model provides Figures 1 to 5 A high-frequency induction welding device for a welded pipe is shown, comprising an equipment platform 1, a processing module 11 is fixedly connected to the left side of the equipment platform 1, a receiving box 12 is fixedly connected to the front side of the equipment platform 1, a first cylinder 18 is fixedly installed near the left side inside the equipment platform 1, a piston rod in the first cylinder 18 is rotatably connected to a first positioning wheel 19, a welding pipe body 3 is slidably connected above the first positioning wheel 19, a mounting plate 2 is slidably connected to the upper surface of the equipment platform 1 near the right side, and a group of discharge guide rails 17 are fixedly connected to the upper surface of the equipment platform 1 and the upper surface of the mounting plate 2, respectively.

[0032] Among them, the processing module 11 is used to weld, cool and straighten the welded pipe. The specific processing method is described in the comparative document and will not be repeated here; the mounting plate 2 continuously pulls the welded pipe to the right, and the processing module 11 processes it during the movement. When the entire welded pipe is fully processed, the mounting plate 2 pulls its left end out of the processing module 11 and sets its left end above the first positioning wheel 19 outside. At this time, the piston rod in the first cylinder 18 contracts inward, driving the first positioning wheel 19 to move downward. During the movement, the left end of the welded pipe contacts the discharge guide rail 17 on the left. At this time, the welded pipe at one end of the mounting plate 2 is released, and the welded pipe will be transferred to the receiving box 12 along the guide rail 2; while discharging, the welded pipe to be processed is sent into the processing module 11, and its right end is set above the first positioning wheel 19. At this time, the mounting plate 2 will immediately move to the leftmost end, fix the right end of the new group of welded pipes, and pull it to the right, thereby improving the processing efficiency and processing quality of the welded pipe, improving automation, and saving manpower.

[0033] Reference Figure 3 The upper surface of the equipment platform 1 is fixedly connected to a support plate 110 at a position located behind the first cylinder 18, and the front surface of the support plate 110 is fixedly connected to a transmission shaft 111 near the upper end. The front end of the transmission shaft 111 is rotatably connected to a second positioning wheel 112, and the second positioning wheel 112 is located above the first positioning wheel 19.

[0034] After the left end of the welded pipe contacts the left discharge guide rail 17, the first positioning wheel 19 continues to move downward, causing the welded pipe to slide downward on the surface of the discharge guide rail 17. When the welded pipe is separated from the first positioning wheel 19, the first cylinder 18 pushes the first positioning wheel 19 upward, so that it cooperates with the second positioning wheel 112 to position a new group of welded pipes.

[0035] Reference Figure 2 Three groups of limit slide grooves 13 are provided on the upper surface of the equipment platform 1 near the right side. The interiors of the front and rear groups of limit slide grooves 13 are fixedly connected to limit rods 15. The interior of the middle limit slide groove 13 is rotatably connected to a threaded rod 16. A first electric motor 14 is fixedly installed on the right side surface of the equipment platform 1. The output end of the first electric motor 14 is fixedly connected to the right end of the threaded rod 16. Three groups of limit sliders 21 are fixedly connected to the lower surface of the mounting plate 2. The front and rear groups of limit sliders 21 are respectively slidably connected to the front and rear groups of limit rods 15, and the middle limit slider 21 is threadedly connected to the threaded rod 16.

[0036] Specifically, the output end of the first electric motor 14 drives the threaded rod 16 to rotate. Due to the limitation of the two sets of limit rods 15, during the rotation of the threaded rod 16, the mounting plate 2 is driven to slide left and right above the equipment platform 1; after the processed welded pipes are discharged, the first electric motor 14 immediately moves the mounting plate to the far left, fixes the right end of a new group of welded pipes, and pulls the new group of welded pipes to the right, and processes the welded pipes through the processing module 11.

[0037] Reference Figure 4 and Figure 5 A fixing plate 22 is fixedly connected to the upper surface of the mounting plate 2, a second electric motor 23 is fixedly installed on the right side of the fixing plate 22 near the upper end, a rotating disk 24 is fixedly connected to the output end of the second electric motor 23, two groups of second cylinders 25 are fixedly installed on the surface of the rotating disk 24, the two groups of second cylinders 25 are symmetrically distributed along the center of the circle, and the output ends of the two groups of second cylinders 25 are fixedly connected to clamping blocks 26.

[0038] At the same time, when the right end of the welding pipe is located between the two sets of clamping blocks 26, the second cylinders 25 on both sides process the clamping blocks 26 on both sides and push them inward at the same time to clamp the welding pipe. At the same time, during the processing, the output end of the second electric motor 23 drives the rotating disk 24 to rotate, thereby driving the welding pipe to rotate.

[0039] Working principle of the utility model: in order to improve the processing efficiency of welded pipes and improve the automation capability of the equipment, a first positioning wheel 19 and a discharge guide rail 17 are arranged on the right side of the processing module 11, and the mounting plate 2 pulls the processed welded pipe to the rightmost end, so that the left end of the welded pipe is erected above the first positioning wheel 19, and at the same time, the welded pipe is automatically stored in the receiving box 12 through the discharge guide rail 17, and the welded pipe is automatically stored and sorted. In the process of discharge, the material is reloaded in the processing module 11, thereby improving the processing efficiency of the welded pipe, improving the automation of the equipment, and improving the adaptability of the equipment.
