[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 、 Figure 6 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of a straightening structure for metal pipes provided by the utility model; Figure 2 for Figure 1 A schematic structural diagram of the telescopic support rod shown; Figure 3 for Figure 1 A schematic top view of a straightening structure for a metal pipe is shown; Figure 4 for Figure 1 A schematic structural diagram of the guide rod shown; Figure 5 for Figure 1 The structural diagram of the correction wheel shown; Figure 6 for Figure 1A schematic diagram of the structure of the limiting base shown. A straightening structure for metal pipes comprises: a support base 1, an electric telescopic rod 6 is installed and connected to the inner walls at both ends of the support base 1, a limiting plate 7 is installed and connected to the inner walls of the side ends of the electric telescopic rod 6, a mounting member 8 is installed and connected to the inner walls at both ends of the limiting plate 7, a straightening wheel 9 is rotatably connected between the inner walls of the side ends of the mounting member 8, a limiting base 20 is installed and connected to the inner wall of the middle top of the support base 1, an electric lifting rod 22 is installed and connected to the inner wall of the middle of the limiting base 20, a lifting plate 23 is installed and connected to the inner wall of the top of the electric lifting rod 22, a limiting member 24 is installed and connected to the inner walls at both ends of the lifting plate 23, a rotating rod 25 is installed and connected between the inner walls of the side ends of the limiting member 24, A fastening clamping plate 26 is rotatably connected to the inner wall of the side end of the rotating rod 25, and a fixing groove 27 is fixedly connected to the inner wall of the side end of the fastening clamping plate 26, and a sliding block 28 is slidably connected to the inner wall of the side end of the fixing groove 27, and a clamping block 29 is installed and connected to the inner wall of the side end of the sliding block 28, and a clamping groove 30 is fixedly connected to the inner wall of the side end of the clamping block 29, and a fastening rod 31 is installed and connected to the inner wall of the side end of the sliding block 28. Guide rods 13 are installed and connected between the inner walls of the side ends of the support base 1, and guide plates 14 are installed and connected to the inner wall of the bottom of the limit plate 7. The guide holes 15 are fixedly connected to the inner wall of the side ends of the guide plate 14, and support members 21 are installed and connected to the inner walls of the bottom ends of both ends of the limiting base 20.

[0023] The bottom inner walls of both ends of the support base 1 are fixedly connected with fastening plates 2, and the inner walls of the side ends of the fastening plates 2 are installed with fastening bolts 3 to facilitate the staff to install and fix the entire device so that it will not become loose during use.

[0024] The top inner walls of both ends of the support base 1 are both installed with mounting rods 4, and the top inner walls of the mounting rods 4 are both fixedly connected with shelves 5. When the device is in use, both ends of the metal pipe can be supported to reduce the use pressure of the device workpiece.

[0025] Telescopic support rods 12 are installed and connected to the inner walls of both ends of the limit plate 7, which can improve the accuracy of the movement of the workpiece of the device and reduce the position deviation during use.

[0026] The guide plates 14 are connected to the inner walls of the side ends of the guide plates 14, and the limit rods 17 are fixedly connected to the inner walls of the tops of the support plates 16. The limit plates 18 are fixedly connected to the inner walls of the side ends of the guide plates 14. The limit grooves 19 are fixedly connected to the inner walls of the side ends of the limit plates 18. In order to reduce the accuracy of the workpiece when the device is moved, when the electric telescopic rods 6 at both ends drive the limit plates 7 to adjust their positions, the limit plates 18 at the side ends will align with the limit rods 17 at the tops of the support plates 16. Subsequently, under continuous driving, the limit grooves 19 on the inner walls of the limit plates 18 will be limited and clamped to the inner walls of the limit rods 17. At this time, when the electric telescopic rods 6 at both ends of the device drive the limit plates 7 to move their positions, the bottom guide plates 14 will move along the direction of the guide rods 13 to limit and clamp the limit plates 18 to the inner walls of the limit rods 17, thereby reducing the position deviation of the workpiece when it moves.

[0028] The working principle of the straightening structure for metal pipes provided by the utility model is as follows:

[0029] When performing straightening operations on metal pipes, first, the electric lifting rod 22 will adjust the top fastening clamping plate 26 to a suitable position, and place metal pipes of different diameters on the inner wall of the lifting plate 23. Then, when limiting and fixing the middle of the metal pipe, the electric lifting rod 22 inside the limiting base 20 will drive the top lifting plate 23 to adjust its downward position. When adjusting the downward position, since the fastening clamping plates 26 at both ends are rotatably connected to the limiting members 24, during continuous downward adjustment, the fastening clamping plates 26 will be limited and stuck on the grooves inside the limiting base 20. At this time, under the continuous lifting and lowering of the electric lifting rod 22, the rotating fastening clamping plates 26 at both ends will be limited to the grooves inside the limiting base 20. Then, the fastening clamping plates 26 at both ends will be rotated from the horizontal position to the vertical position, thereby fixing the metal pipes of different diameters to reduce the tediousness in use. Then, the fastening rod 31 is rotated for further locking.

[0030] Compared with related technologies, the straightening structure for metal pipes provided by the present invention has the following beneficial effects:

[0031] To enhance the device's convenience when straightening metal pipes, a clamping block 29 with an automatic limit function automatically adjusts its position based on the pipe's diameter, reducing positional deviation during the limiting process and improving the device's practicality. Furthermore, when the straightening wheel 9 is straightening, pits and other defects on the pipe surface may cause the workpieces at either end of the device to deviate from the limit position. The coordinated operation of the limit plate 18 and limit rod 17 reduces positional deviation during the movement of the straightening wheel 9, thereby improving force uniformity on the workpieces during use and reducing wear on the straightening wheel 9.
