[0026] In this embodiment, when this type of bending mechanism for sheet metal parts is in use, in order to be able to use sheet metal objects of different sizes, therefore, the first motor 18 is started, so that the movable arm 12 starts to rotate, and then the arm span of the connecting arm 13 will be expanded, thereby increasing the distance between the two pedestals 14. This design can improve the versatility and applicability of the equipment, and there is no need to make additional adjustments or replace components for each size of object. When the adjustment is completed, the telescopic rod 17 is retracted to cause the side plate 16 to change its angle. During the change process, the side plate 16 will drag the rectangular frame 15 downward to buckle and fix one end of the object. At this time, the bending device 113 is started to bend the object. When the bending is completed, in order to prevent the object from rebounding, therefore, the second motor 19 is started, so that the bulletproof plate 111 moves under the influence of the lead screw 110 and covers the bent part, which can effectively prevent the rebounding phenomenon after bending.

One end of the folding rod 21 is slidably connected to the inner wall of the top side of the guide rail 22. One side of the guide rail 22 is fixedly connected to one side of the platen 11. The other end of the folding rod 21 is fixedly connected to one end of the pedestal 14.
[0030] In this embodiment, a folding rod 21 is installed on the pedestal 14. When the pedestal 14 moves, the pulleys on the folding rod 21 will roll on the guide rail 22, which can keep the pedestal 14 stable during the movement.

At the same time, the pulleys can reduce the friction and wear between the pedestal 14 and the guide rail 22, which helps to extend the service life of the equipment, reduce the frequency of maintenance and replacement of parts, and lower the production cost.
[0031] Working principle:
[0032] As Figures 1-4 shown, start the first motor 18, so that the movable arm 12 starts to rotate, and then the arm span of the connecting arm 13 will be expanded, thereby increasing the distance between the two pedestals 14. This design can improve the versatility and applicability of the equipment, without the need for additional adjustments or replacement of parts for each size of the object. After the adjustment is completed, retract the telescopic rod 17 to cause the side plate 16 to change its angle. During the change process, the side plate 16 will drag the rectangular frame 15 downward to buckle and fix one end of the object. At this time, start the bending device 113 to start bending the object. When the bending is completed, in order to prevent the object from rebounding, therefore, start the motor to make the bulletproof plate 111 move under the influence of the lead screw 110 and cover the bending part, which can effectively prevent the rebound phenomenon after bending;
[0033] When the pedestal 14 moves, the pulleys on the folding rod 21 will roll on the guide rail 22, which can keep the pedestal 14 stable during the movement. This stable movement is crucial for the bending device 113. Especially when processing long-sized or heavy workpieces, it can reduce vibrations or errors caused by unstable movement. At the same time, the pulleys can reduce the friction and wear between the pedestal 14 and the guide rail 22.
