[0037] In the present invention, according to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a feed end 4 is provided on the side surface of the operating body 1 , an anti-rebound component 11 is installed on the top surface of the operating body 1 , and a pipe 5 is connected to the inner plug of the feed end 4 , and the pipe 5 passes through the annular electromagnetic guide rail 8 .

[0038] The anti-rebound component 11 includes a fixed buffer frame 110, which is installed inside the working body 1. The side end of the fixed buffer frame 110 is fastened with a force frame 114. Two groups of force-bearing wheels 118 are symmetrically installed on the left and right ends of the surface of the force frame 114. The center ends of the two groups of force-bearing wheels 118 are inserted into the force frame 114 through a synchronous shaft.

[0039] The bottom of the two sets of synchronous shafts are installed with a first chain gear structure 117, and the bottom of the other set of synchronous shafts is installed with a second chain gear structure 1190.

The control brushless motor 119 is fastened to the inner wall surface of the working body 1 through a hoop frame, and the side end of the force frame 114 is rotatably connected with a threaded screw 115 through a bearing.

[0040] The screw motor 111 is installed at the side end of the threaded screw 115, and sliding guide columns are installed at both left and right ends of the threaded screw 115. The threaded screw 115 and the sliding guide column are externally slidably connected with a pressing wheel 116.

When it is detected that there is no rebound, the double-axis pneumatic cylinder 112 is started to drive the slide plate 113 to the side of the pressing wheel 116, so that the pressing wheel 116 cannot exert a compressive force on the pipe 5, and through the rotation of the two sets of force-bearing wheels 118, the pipe 5 is driven to output, completing the overall pipe 5 bending operation.

The micro-electric telescopic guide rod 98 is used to adjust the position of the micro-microwave heating generator 99, and the local bending area of ​​the pipeline 5 is heated to soften it, thereby reducing the rebound phenomenon during the bending process, improving the bending quality and bending Efficiency, to ensure the overall bending accuracy, the bent pipe 5 moves forward to reach the force-bearing wheel 118, and the fixed buffer frame 110 is installed inside the working body 1 to provide support and fixation, and then the brushless motor 119 is started to control the first chain gear structure 117 and the second chain gear structure 1190 to rotate in turn, so that the synchronous shaft drives the two sets of force-bearing wheels 118 to rotate at the force-bearing frame 114, and then according to the curvature feedback of the bending angle of the curvature angle laser detector 10, when rebound is detected, the threaded screw 115 is driven by the screw motor 111, and the displacement distance of the pressing wheel 116 is adjusted with the cooperation of the sliding guide column, and it contacts the pipe 5 to apply pressure and perform a reverse bending.That is, a small bending is performed in the opposite direction to offset the rebound, such as the initial bending of 100 degrees, and then the reverse bending of 5 degrees, and finally a bending angle of 95 degrees is obtained. When no rebound is detected, the double-axis pneumatic cylinder 112 is started to drive the slide plate 113 to the side of the pressing wheel 116, so that the pressing wheel 116 cannot exert a compressive force on the pipe 5, and the pipe 5 is driven to output through the rotation of the two sets of force-bearing wheels 118. Through multiple bendings, the bending angle of the pipe 5 is gradually adjusted until the design requirements are met.

10. A method for using a pipe bending device, characterized in that: The pipe bending device according to claim 9 is used, comprising the following steps: S1, the pipe (5) enters from the feed end (4), and then the main bending component (3) performs a pre-bending operation on the entering pipe (5); S2, the arc-shaped electromagnetic guide rail (6) then drives the vertical guide rail (7), the annular electromagnetic guide rail (8) and the bending control component (9) to start from the starting end, and synchronously follows the bending component (3) to slide and adjust the bending degree of the entering pipe (5); S3, then, with the cooperation of the bending control component (9), the pipe (5) is preheated and subjected to heating follow-up treatment during the bending process to improve the bending accuracy and efficiency; S4. Then, the pipe (5) continues to move to the anti-rebound component (11), and the anti-rebound component (11) is used to pressurize and bend the bent pipe (5) again, so as to further cause the pipe (5) to undergo plastic deformation, thereby reducing the influence of rebound on the accuracy of the bending.
