An adjustment mechanism is provided on the top of the processing table 1, and the device can be adjusted by the adjustment mechanism, so as to facilitate the processing of pipelines of different sizes;

[0019] During processing, the pipe is placed on the top of the processing table 1, and the device is adjusted by the adjustment mechanism. During subsequent processing, pipes of different sizes are placed on the processing table 1, and the pipes are conveniently moved by multiple conveying rollers 4, so that subsequent components can bend the pipes.

[0020] Reference Figure 2-3 The adjusting mechanism includes two slide grooves 5, which facilitate the movement of the subsequent clamping seat 7. The two slide grooves 5 are symmetrically arranged on both sides of the installation groove 3. The inside of the slide grooves 5 on both sides is rotatably connected with a screw rod 6. The screw rods 6 on both sides are installed with a clamping seat 7, so that the screw rod 6 can drive the clamping seat 7 to move, and the clamping seat 7 is convenient for limiting the pipeline, so as to facilitate the subsequent bending processing. The clamping seats 7 on both sides are symmetrically arranged on both sides of the installation groove 3. A plurality of rollers 8 are rotatably connected to the clamping seat 7, and the movement of the pipeline is convenient through the roller 8. The processing table 1 is symmetrically rotatably connected with hand wheels 9 on both sides. The hand wheels 9 on both sides are respectively fixedly connected to the ends of the screw rods 6 on both sides, so that the screw rod 6 is driven to rotate by the hand wheels 9. A mounting hole 10 is opened on one side of the top of the processing table 1. The mounting hole 10 is arranged on one side of the end of the clamping seat 7, and a contact switch is fixedly connected to the inside of the mounting hole 10 11. The contact switch 11 is a prior art product. The contact switch 11 is used to conveniently control the operation of subsequent devices. A fixing frame 12 is fixedly connected to the top of the processing table 1. The fixing frame 12 is arranged at one side of the end of the clamping seat 7. The fixing frame 12 facilitates the installation of the hydraulic cylinder 13. The hydraulic cylinder 13 is installed on the fixing frame 12. The hydraulic cylinder 13 provides power for subsequent bending. The mounting hole 10 is arranged at one side of the end of the hydraulic cylinder 13.

The screw rods 6 on both sides are driven by rotating the hand wheels 9 on both sides to make the clamping seat 7 move inside the slide groove 5, thereby adjusting the spacing between the clamping seats 7 on both sides. Subsequently, the pipe is placed inside the clamping seats 7 on both sides, and the movement of the pipe is facilitated by multiple conveying rollers 4 and rollers 8. When the pipe moves, it presses the contact switch 11, thereby starting the hydraulic cylinder 13, and the hydraulic cylinder 13 drives the pipe bending head 14 to move, so that the pipe bending head 14 applies pressure to the pipe, thereby bending the pipe.
