A slider 4 is slidably connected inside the chute 3. One end of the slider 4 is provided with an auxiliary wheel 5;

[0020] The adjusting mechanism includes a driving motor 6, a driving rod 7 and an auxiliary rod 8. The driving motor 6, the driving rod 7 and the auxiliary rod 8 are all arranged inside the cabinet body 1. The output end of the driving motor 6 is meshed with one end of the driving rod 7 through a gear. A connecting seat 9 is provided at the bottom of the slider 4. The outer surface of the driving rod 7 is threadedly connected with the connecting seat 9. The auxiliary rod 8 penetrates and connects with one side of the connecting seat 9.

[0021] The driving motor 6 rotates to drive the driving rod 7 to rotate. The driving rod 7 is threadedly connected with the connecting seat 9. The rotation of the driving rod 7 can drive the connecting seat 9 to move, and then drive the slider 4 to move. The chute 3 limits the moving direction of the slider 4. The internal auxiliary rod 8 is arranged on the other side of the driving rod 7. The cooperation between the auxiliary rod 8 and the driving rod 7 can improve the stability of the slider 4 when moving. The auxiliary wheel 5 and the guide wheel 2 cooperate. When bending a pipe, the auxiliary wheel 5 and the guide wheel 2 can rotate, so that the pipe fitting can pass through more smoothly. A traction mechanism can be provided on one side of the cabinet body 1 for pulling the pipe fitting to be processed to move.

[0022] In this embodiment, as a preferred solution, a synchronous belt 19 is provided at one end of the driving rod 7.

Both the driving rod 7 and the auxiliary rod 8 are threadedly connected with the inside of the connecting seat 9.

[0023] The driving rod 7 is connected with the auxiliary rod 8 through the synchronous belt 19. When the driving rod 7 rotates, it can drive the auxiliary rod 8 to rotate together. And both the driving rod 7 and the auxiliary rod 8 are threadedly connected with the connecting seat 9 at the same time.

[0030] In the present utility model, the working steps of the device are as follows:

[0031] 1. Before pipe bending, use the fixing screw 11 to fix the guide wheel 2 at the required position, adjust the position of the moving block 13, and use the top rod 15 to fix the position of the moving block 13.

[0032] 2. After fixing, pass the pipe fitting to be bent through the gap between the guide wheel 2 and the auxiliary wheel 5, and pass through the limiting grooves 14 on both sides. Start the driving motor 6 to drive the slider 4 to move, so that the pipe fitting is gradually bent into the required shape.

[0033] 3. After bending to the limit position of the limiting groove 14, loosen the top rod 15, slide the top rod 15 towards the processing side, so that there is a certain gap between the pipe fitting to be processed and the limiting groove 14, and then tighten the top rod 15 and continue the processing.
