Description

Technical Field

[0001] This utility model relates to the field of high-frequency welded pipe technology, specifically to an adjustment structure and a high-frequency welded pipe forming equipment. Background Technology

[0002] High-frequency welded pipe forming equipment is a specialized device designed specifically for the production of high-frequency welded pipes. Its core principle lies in the ingenious use of the physical characteristics of high-frequency current, namely, the skin effect to highly concentrate the current on the edge surface of the metal pipe, and the proximity effect to generate magnetic field interaction between adjacent edges, causing the edge area to heat up rapidly to a molten state, thereby achieving rapid and efficient welding of the metal pipe under extrusion.

[0003] For example, patent CN113458196B, authorized by patent publication number CN113458196B, discloses a forming mold for high-frequency welded pipes, relating to the field of forming mold technology. This forming mold for high-frequency welded pipes consists of an electromagnet ring, an arc-shaped scraper, and a collection box, which can clean and scrape away iron filings on the surface of the pipe seam, improving the quality of the high-frequency welded pipe. It can effectively reduce the difficulty of disassembling and assembling the forming mold, shorten the disassembly and assembly time, and improve the working efficiency of the mold. Through the combined use of a square fixed shaft and a limiting slider, it can effectively prevent the forming mold from loosening, ensuring the pipe winding effect of the mold.

[0004] The above-mentioned device still has certain defects: Although the aforementioned device can effectively prevent the forming mold from loosening and ensure the effectiveness of the pipe rolling, the two forming molds in this device are mounted on the mounting plate via a square fixed shaft, and both are in the same vertical plane. This installation method has certain limitations in actual production. When it is necessary to produce welded pipes of different diameters, due to structural limitations, the distance between the two molds is difficult to adjust flexibly according to production needs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable structure and a high-frequency welded pipe forming equipment, making it more convenient to adjust the forming mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment structure, including a bracket, with a main bidirectional lead screw and a secondary bidirectional lead screw rotatably connected to both ends of one side of the bracket, a lifting motor fixedly connected to the top of the bracket, the output end of the lifting motor fixedly connected to the main bidirectional lead screw, lifting blocks threadedly connected to the upper and lower ends of the main bidirectional lead screw, the end of the lifting block away from the main bidirectional lead screw threadedly connected to the secondary bidirectional lead screw, and synchronous pulleys fixedly connected to the upper ends of both the main bidirectional lead screw and the secondary bidirectional lead screw, with a synchronous belt meshing with the synchronous pulley.

[0007] A high-frequency welded pipe forming device includes a forming mold and the aforementioned adjustment structure. A rotating shaft is rotatably connected to the middle position of the lifting block, and the forming mold is installed at the end of the rotating shaft away from the lifting block.

[0008] Furthermore, a rotary motor is fixedly connected to the side of the lifting block away from the rotating shaft, and the output end of the rotary motor is fixedly connected to the rotating shaft.

[0009] Furthermore, slots are provided at the middle position and the lower end of the rotating shaft away from the lifting block. Insert plates are slidably connected inside the slots. An end plate is fixedly connected to the end of the insert plate away from the rotating shaft. Threaded holes are provided on both the rotating shaft and the insert plate, and fixing bolts are threaded into the threaded holes.

[0010] Furthermore, a stop block is fixed to the top of the rotating shaft at the end away from the lifting block.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This type of adjustment structure and high-frequency welded pipe forming equipment only requires starting the lifting motor when it is necessary to adjust the distance between the forming molds. The lifting motor will drive the main bidirectional lead screw to rotate, thereby causing the two lifting blocks to move closer or further apart, thus adjusting the distance between the forming molds. The adjustment process is simple, convenient and easy to operate. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-4An adjustable structure and high-frequency welded pipe forming equipment includes a support 1. A main bidirectional lead screw 2 and a secondary bidirectional lead screw 3 are rotatably connected to both ends of one side of the support 1. A lifting motor 6 is fixedly connected to the top of the support 1. The output end of the lifting motor 6 is fixedly connected to the main bidirectional lead screw 2. Lifting blocks 7 are threadedly connected to both the upper and lower ends of the main bidirectional lead screw 2. The end of the lifting block 7 away from the main bidirectional lead screw 2 is threadedly connected to the secondary bidirectional lead screw 3. Synchronous pulleys 4 are fixedly connected to the upper ends of both the main bidirectional lead screw 2 and the secondary bidirectional lead screw 3. A synchronous belt 5 that meshes with the synchronous pulley 4 is sleeved on the outside of the synchronous pulley 4.

[0016] The adjustment structure and high-frequency welded pipe forming equipment of this utility model can adjust the distance between the forming molds 10 by simply starting the lifting motor 6. The lifting motor 6 will drive the main bidirectional lead screw 2 to rotate, thereby driving the two lifting blocks 7 to move closer or further apart, thus adjusting the distance between the forming molds 10. The adjustment process is simple, convenient and easy to operate. At the same time, the synchronous wheel 4 and the synchronous belt 5 make the main bidirectional lead screw 2 and the secondary bidirectional lead screw 3 rotate synchronously, making the lifting blocks 7 more stable.

[0017] A high-frequency welded pipe forming device includes a forming mold 10 and the aforementioned adjustment structure. A rotating shaft 8 is rotatably connected to the middle position of a lifting block 7, and the forming mold 10 is installed at the end of the rotating shaft 8 away from the lifting block 7.

[0018] like Figure 1 and Figure 2 As shown, a rotary motor 9 is fixedly connected to the side of the lifting block 7 away from the rotating shaft 8, and the output end of the rotary motor 9 is fixedly connected to the rotating shaft 8.

[0019] Specifically, during normal use, the rotary motor 9 drives the rotating shaft 8 to rotate, which in turn drives the molding die 10 to rotate.

[0020] like Figure 4 As shown, slots 13 are provided at the middle position and the lower end of the rotating shaft 8 away from the lifting block 7. Insert plates 14 are slidably connected inside the slots 13. An end plate 11 is fixedly connected to one end of the insert plate 14 away from the rotating shaft 8. Threaded holes 15 are provided on both the rotating shaft 8 and the insert plate 14. Fixing bolts 16 are threadedly connected inside the threaded holes 15.

[0021] Specifically, when installing the molding mold 10, simply suspend the molding mold 10 on the rotating shaft 8, insert the insert plate 14 fixed on the end plate 11 into the slot 13, and then screw the fixing bolt 16 into the threaded hole 15. The fixing method is simple and easy to operate.

[0022] like Figure 4 As shown, a stop block 12 is fixedly connected to the top of the end of the rotating shaft 8 away from the lifting block 7.

[0023] Specifically, after the molding die 10 is suspended at the end of the rotating shaft 8, the stop block 12 will restrict the molding die 10 to prevent the molding die 10 from detaching from the rotating shaft 8.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
