Working principle:

when the high-stability steel pipe bending machine with linkage capability is required to be used, firstly, a user can control the traveling motor 9 to enable the traveling motor 9 to realize leftward movement of the sliding platform 10 by controlling the rotation of a gear at the tail end of the traveling motor and the meshing of the traveling motor and the rack 11, then one end of a pipeline 13 to be bent is clamped on the inner wall of the pipeline clamping part 7, after the clamping is finished, the traveling motor 9 is controlled to enable the sliding platform 10 to drive the pipeline 13 to move rightward until the corresponding position to be bent of the pipeline 13 is consistent with the rear end position of the fixed mould 405, and then all preparation works before bending are finished, and the specific bending processing is as follows:

1. bending driving process: firstly, the power motor 305 can be controlled to start, so that an output shaft of the power motor 305 can drive an input shaft of the worm and gear coupler 303 to rotate through the first belt pulley 306, the second belt pulley 307 and the belt 304, then, the output shaft of the worm and gear coupler 303 can drive the disc 404 to rotate through the cooperation of the pinion 302 and the bull gear 301, at this time, the round rod 407 is clamped at one side of the left part of the chute 402, when the disc 404 is bent and rotated, the frame 403 can be driven to rotate clockwise through the cooperation of the chute 402 and the round rod 407, and then the movable die 401 is driven to bend and rotate, one side bending processing is realized, and in the rotating process of the frame 403, the position of the first base 408 connected with the first base 408 also changes, so that the positions of the first bases 408 at two sides become shorter, and then the first spring 409 is compressed.

2. Gap resetting: after one side of the workpiece is machined, the power motor 305 needs to be controlled to rotate reversely, so that the frame 403 rotates reversely, the movable die 401 rotates back to the position (as shown in fig. 1) in the same vertical direction as the fixed die 405, in the process, the first spring 409 is compressed in the bending process, so that the first spring 409 applies a counter-clockwise reaction force to the frame 403, further, the round rod 407 can be tightly pressed on the left side of the chute 402, synchronous counter-clockwise rotation reset of the frame 403 and the round disc 404 is ensured, in the limiting position shown in the figure, the tail end of the material blocking rod 406 is attached to one side of the machining platform 1, so that the frame 403 can not rotate counter-clockwise any more, the round disc 404 can still rotate counter-clockwise under the driving of the power motor 305, at the moment, the round rod 407 is not clamped on one side of the chute 402, but the chute 402 slides on the outer wall of the round rod 407, that is, and the round disc 404 can rotate counter-clockwise by a certain angle when the frame 403 rotates counter-clockwise to the limiting position, and the clearance reset process is completed.

3. Linkage clamping process: in the process of rotating the disc 404 counterclockwise by a certain angle, the driving roller 512 can rotate counterclockwise along with the rotation of the disc 404, when the frame 403 rotates to the limit position, the outer wall of the driving roller 512 is attached to the right end of the end plate 511, and when the driving roller 512 continuously rotates left, the sliding block 501 can be driven to move left through the end plate 511, at this time, the sliding block 501 continuously extrudes the third spring 502, and due to the inclined plane design of the inclined beam 503, when the sliding block 501 moves left, the movable roller 508 moves backwards under the action of the fourth spring 507, and does not extrude the rear side of the outer wall of the pipeline 13, and continuously rotates, so that the rotatability of the second base 517 and the slidability of the second sliding rod 516 can be realized, and after the sliding block 501 moves past the center point position of the cross beam 509, the sliding block 501 can be enabled to move to the limit position better under the action of the release extrusion elasticity, at this time, the movable clamping block 506 moves backwards to be separated from the clamping of the pipeline 13, the clamping between the driving part and the pipeline clamping part is effectively avoided, the driving part designed independently and the bending part is not required to be in a loose sequence, and the manual operation is easy to cause the failure of the sequential bending operation of the bending operation.

Meanwhile, after the traveling motor 9 is controlled to complete the forward movement of the part to be bent of the pipeline 13, the user can control the power motor 305 again, so that the power motor 305 drives the disc 404 to rotate, under the action of the power motor, the driving roller wheel 512 also rotates clockwise, at the moment, under the action of the second spring 502 and the magnetic attraction of the end plate 511 and the driving roller wheel 512, the sliding block 501 moves rightwards, so that the movable clamping block 506 returns to the clamping state of the pipeline 13 again, at the moment, the end plate 511 and the driving roller wheel 512 are separated from each other, the position of the sliding groove 402 ensures the adhesion between the left side of the inner wall of the sliding groove and the round rod 407 again, so that the frame 403 can be synchronously driven to rotate clockwise, compared with the prior art, if the bent rotating part and the clamping part are required to be linked together, a more direct transmission connection process is required, namely the rotating part is required to move along with the clamping part, the driving system is not involved in the bending rotation process so as to ensure the clamping effect of the pipeline, and the rotating part and the clamping part are mutually influenced by the linkage system, so that the power assembly 3 is designed, the power motor 305 is controlled to rotate reversely, the frame 403 rotates reversely, the movable die 401 rotates back to the position in the same vertical direction as the fixed die 405, in the process, the first spring 409 is compressed due to the compression of the first spring 409 in the bending process, so that the first spring 409 applies a counter-clockwise reaction force to the frame 403, and the round rod 407 can be tightly pressed on the left side of the chute 402, the synchronous counter-clockwise rotation reset of the frame 403 and the round disc 404 is ensured, and in the extreme position shown in the figure, the tail end of the material blocking rod 406 is attached to the side corresponding to the processing platform 1, so that the frame 403 can not rotate counter-clockwise any more, the disc 404 can still rotate anticlockwise under the drive of the power motor 305, at this time, the round rod 407 is not clamped at one side of the chute 402, but the chute 402 slides on the outer wall of the round rod 407, that is, the disc 404 can still rotate anticlockwise by a certain angle when the frame 403 rotates anticlockwise to the limit position, thus realizing the linkage that the disc 404 can synchronously rotate to complete bending and can automatically rotate at the limit position for the clamping part, effectively avoiding the relatively direct transmission connection process, being inconvenient to realize the bending rotation process, ensuring the clamping effect of the pipeline due to the fact that the transmission system is not intervened, and causing the problem of the mutual influence of the rotating part and the clamping part due to the linkage system.

4. The technical advantages are that:
