The hydraulic cylinder 9 starts and drives the pressing plate 10 to move toward the steel pipe, and the steel pipe is clamped and fixed by the upper arc groove 11 and the lower arc groove 8.

[0021] Reference Figure 1 and Figure 2The bending assembly includes a driving motor 12 fixedly connected to the inner wall of the bottom of the circular groove 7, the output end of the driving motor 12 is fixedly connected to a processing disk 13, a fixed roller 14 is fixedly connected to the center position of the upper surface of the processing disk 13, and a movable roller 15 is fixedly connected to the surface of the processing disk 13 and near the edge. When the driving motor 12 is started, the driving motor 12 drives the processing disk 13 to rotate, and the processing disk 13 drives the movable roller 15 to rotate. The movable roller 15 rotates and extrude and bends the steel bar together with the fixed roller 14.

[0022] Reference Figure 1 and Figure 3 The inner walls of the lower arc groove 8 and the upper arc groove 11 are both provided with rubber pads 16, so as to avoid the upper arc groove 11 and the lower arc groove 8 directly contacting the steel pipe when clamping and fixing the steel pipe and causing wear to the steel pipe.

[0023] Reference Figure 1 At least one outer wall of the slider 5 is tightly fitted with the inner wall of the transverse groove 2, thereby preventing the slider 5 from rotating and deviating when it moves outside the screw rod 4.

[0024] The implementation principle of a bending die for steel pipe processing in the embodiment of the present application is as follows: the steel pipe to be bent is placed inside the lower arc groove 8, the hydraulic cylinder 9 is started, and the hydraulic cylinder 9 is started to drive the pressure plate 10 to move toward the steel pipe, and the steel pipe is clamped and fixed by the upper arc groove 11 and the lower arc groove 8.
