For example, in the case of unilateral bending, one cylinder 401 can be controlled to start through the control panel 6, thereby realizing unilateral or symmetrical bending of bogies adapted to different specifications, which is simple to operate and highly practical.

[0025] like Figure 1-2 As shown, the adjustment mechanism 3 also includes a motor 304, a rectangular groove 301 is opened on the top of the workbench 1, and the bidirectional screw 302 is rotatably installed in the rectangular groove 301, the motor 304 is installed on the right side of the bidirectional screw 302, and the motor 304 is installed on the right side of the workbench 1. In this embodiment, the motor 304 is started to drive the bidirectional screw 302 to rotate, and the two rectangular blocks 303 slide close to each other on the bidirectional screw 302 and in the rectangular groove 301, and the rectangular groove 301 serves to limit the sliding of the rectangular blocks 303, thereby preventing the rectangular blocks 303 from rotating with the rotation of the bidirectional screw 302, resulting in instability.

[0026] like Figure 1-3As shown, the auxiliary mechanism 5 includes two square columns 501, which are installed on the top of the workbench 1, and the control panel 6 is installed on the surface of the front square column 501.

A long plate 504 is threadedly installed on the outer wall of the two one-way screws 503, and the long plate 504 is slidably installed on the inner wall of the two fixed shells 502. An arc beam 510 is installed on the bottom of the long plate 504. In this embodiment, when the two one-way screws 503 rotate, the long plate 504 is driven to slide longitudinally on the two one-way screws 503 and in the fixed shell 502, and the arc beam 510 moves longitudinally therewith and contacts with the bogie, so that the bogie is fixed in the mounting groove 404 of the elbow 403, thereby adapting to the thickness of different bogies.

A connecting shell 508 is installed on the tops of the two fixed shells 502, and a fixed column 506 is rotatably installed in the connecting shell 508. Two worms 507 are installed on the outer wall of the fixed column 506, and the worms 507 are meshed with the worm wheels 505. A second motor 509 is installed on the front side of the fixed column 506, and the second motor 509 is installed on the front side of the connecting shell 508. In this embodiment, the second motor 509 is started to drive the fixed column 506 to rotate, and the two worms 507 rotate accordingly, driving the two worm wheels 505 to rotate, and the two one-way screws 503 rotate accordingly.

For example, when bending on one side, the control panel 6 can be used to control and start one cylinder 401, so as to achieve unilateral or symmetrical bending of bogies with different specifications. The operation is simple and practical. The motor 304 is started to drive the bidirectional screw 302 to rotate, and the two rectangular blocks 303 are on the bidirectional screw 302 and in the rectangular groove 301. The two one-way screws 503 rotate, driving the long plate 504 to slide longitudinally on the two one-way screws 503 and in the fixed shell 502, and the arc beam 510 moves longitudinally therewith and contacts with the bogie, so that the bogie is fixed in the mounting groove 404 of the elbow 403, thereby achieving adaptation to different bogie thicknesses. 3 is set to improve the stability of the rotation of the one-way screw 503 and avoid falling off. The second motor 509 is started to drive the fixed column 506 to rotate, and the two worms 507 rotate accordingly, driving the two worm wheels 505 to rotate, and the two one-way screws 503 rotate accordingly. The worm wheels 505 and the worm 507 cooperate with each other to have self-locking properties, which improves the stability of the bogie limit. The friction pad made of rubber material is set to increase the friction resistance with the bogie to avoid offset during the bending process of the bogie.
