[0029] Working principle: During the production of ordinary padlock hardware, the lock beam needs to be processed separately, and then the formed lock beam is assembled with the lock body. In the production of ordinary locks, when processing the lock beam, a bending device needs to be used for auxiliary cooperation. However, when the existing lock beam bending device is in operation, it can only process single lock beams step by step, resulting in a low operation efficiency within the same time period. This application acts through a bending device. By placing the lock beam to be bent in the positioning groove 413 of the lower die 411, the hydraulic cylinder 402 in the installation cavity 401 is opened, and the hydraulic rod 403 pushes the action frame 404 downward. Under the action of the collar 407 and the positioning plate 408, the latch 409 moves along the card slot 410, causing the action roller 405 to move downward towards the lower die 411. Under the action of the pressure groove 406 and the structure groove 412, the forming of the lock beam is achieved, realizing the effect of mass production and improving the production efficiency. Additionally, for lock beams of different sizes, the bending device can be adjusted so that lock beams of different sizes can be properly formed and produced. Apply a force to the first fixing plate 505 to make the first fixing plate 505 disengage from the inside of the first fixing hole 503. Then, apply a force to the action frame 404 to make the action frame 404 disengage from the buckling groove 501 along the structure hole 502, achieving the rapid replacement of the upper structure. Subsequently, apply a force to the second fixing plate 508 to make the second fixing plate 508 disengage from the second fixing hole 507, and apply a thrust to the lower die 411 to make the lower die 411 drive the convex slider 509 to disengage from the inside of the convex chute 506, achieving the rapid replacement of the bending device and improving the working efficiency of the replacement operation.
