[0019] The utility model is rotatably connected to the frame 1 through the fixed wheel 3 provided. When bending the steel pipe, the steel pipe is placed between the fixed wheel 3 and the adjusting wheel 4. According to the thickness of the steel pipe, the spacing between the adjusting wheel 4 and the fixed wheel 3 is adjusted to adapt to the steel pipes of different thicknesses. After the adjustment is completed, the hydraulic cylinder 2 is started to squeeze the steel pipe at the middle of the two fixed wheels 3 to perform a bending operation. The above operation can quickly adapt to the bending requirements of steel pipes of different thicknesses by adjusting the spacing between the fixed wheel 3 and the adjusting wheel 4. The operation is convenient to operate and has a wide range of applications.
[0020] Specifically, it also includes: a fixed wheel 3 is slidably connected to the frame 1, and the distance between the two fixed wheels 3 is adjustable; an adjusting wheel 4 is slidably connected to the frame 1, and the distance between the two adjusting wheels 4 is adjustable.
[0021] In the above embodiments, by adjusting the distance between the two fixed wheels 3, the adjustment is further facilitated, different bending requirements are further adapted, and the practicality of the device is further improved.
[0022] Specifically, it also includes a first slide groove 5, two first supports 6, a guide column 7 and a bidirectional screw rod 8. The frame 1 is provided with a first slide groove 5. The two first supports 6 correspond to the fixed wheel 3 one by one. The first support 6 slides in the first slide groove 5. The fixed wheel 3 is rotatably connected to the first support 6. The guide column 7 is connected to the frame 1. The guide column 7 passes through the two first supports 6. The first support 6 is slidably connected to the guide column 7. The bidirectional screw rod 8 is rotatably connected to the frame 1. The two first supports 6 are respectively screwed to the two ends of the bidirectional screw rod 8.
[0023] In the above embodiments, the stable sliding of the fixed wheel 3 on the frame 1 is achieved by the cooperation of the first slide groove 5 and the first support 6, and the two first supports 6 are moved closer to or farther away from each other by manually or by a motor-driven rotation of the bidirectional screw rod 8, thereby adjusting the distance between the two fixed wheels 3 to meet more bending requirements.
[0024] Specifically, it also includes a second slide groove 9, two second supports 10 and two screw rod members 11. The second slide groove 9 is opened on the upper side of the frame 1. The two second supports 10 are respectively slidably connected to the two sides of the second slide groove 9. The second supports 10 correspond to the first supports 6 one by one. The two screw rod members 11 correspond to the second supports 10 one by one. The screw rod members 11 pass through the corresponding second supports 10 and are screwed into the corresponding first supports 6. The screw rod members 11 are movably connected to the corresponding second supports 10, and the adjusting wheel 4 is rotatably connected to the corresponding screw rod member 11.
[0025] In the above embodiments, the second slide groove 9 and the second support 10 cooperate to realize the sliding of the two screw rods 11 and the two adjusting wheels 4, and then adapt to the fixed wheel 3 to adjust the spacing. By rotating the screw rod 11, the screw rod 11 moves up and down, and then drives the adjusting wheel 4 to move up and down to adjust the spacing between the adjusting wheel 4 and the fixed wheel 3.
[0026] Specifically, it also includes a connecting plate 12, a threaded column 13 and an arc-shaped push block 14. The connecting plate 12 is fixedly connected to the output end of the hydraulic cylinder 2, the threaded column 13 is fixedly connected to the connecting plate 12, the arc-shaped push block 14 is movably sleeved on the threaded column 13, and nuts are provided on both sides of the arc-shaped push block 14.

[0029] In the above embodiments, when adjusting the spacing between the two adjusting wheels 4 and the fixed wheel 3 , the scale 15 may be observed to ensure that the heights of the two adjusting wheels 4 are substantially consistent.
[0030] The working principle of the utility model is as follows: when performing a bending operation, the device is adjusted according to the thickness of the steel pipe and the bending requirement, the spacing between the fixed wheel 3 and the adjusting wheel 4 is adjusted, and the screw rod 11 is rotated by a wrench so that the screw rod 11 slides up and down in the first support 6, thereby driving the adjusting wheel 4 to slide up and down. During this process, the screw rod 11 rotates and slides on the second support 10, and the scale 15 is observed to ensure that the heights of the adjusting wheels 4 on both sides are basically consistent. After the height adjustment of the adjusting wheel 4 is completed, the bidirectional screw rod 8 is controlled by a wrench or a motor to rotate, driving the first supports 6 on both sides, and the first supports 6 on both sides are close to or away from each other, so that the fixed wheel 3, the adjusting wheel 4, the second support 10, and the screw rod 11 move synchronously. After adjusting the spacing between the two fixed wheels 3, an arc-shaped push block 14 of appropriate size is installed according to the thickness of the steel pipe and the bending requirement. Then, the steel pipe is placed on the frame 1 so that the steel pipe is between the fixed wheel 3 and the adjusting wheel 4, and the hydraulic cylinder 2 is started for extrusion and bending.
