It can bend products into cones, arcs, circles or right angles, etc., and can also design and process special shape molds according to requirements. When bending plates, the bending machine must first position the plates, that is, the position of the plates relative to the bending center line. The specific operation method is: first return the rear stopper to the zero reference point, and then move the stopper to a specific position according to the bending needs, put the plate to be processed into the mold, and use the stopper position as a reference to locate the plate size and bend it. Therefore, during the use of the bending machine, the stopper needs to be constantly adjusted.

[0003] In the Chinese patented new type of fine-adjustable rear stopper for bending machine (patent number: CN106513481A), in the device, the guide block is moved forward and backward by rotating the adjusting screw, thereby driving the stopper connected by the connecting plate to move forward and backward. The rotation of the adjusting screw is achieved by adjusting the knob, which has a scale to ensure the adjustment accuracy. The horizontal accuracy of the stopper can be achieved by applying pressure to the left end of the stopper by adjusting the bolt and rotating it with the rotating shaft as the axis.

[0004] However, in this device, the operation of adjusting the stopper finger by rotating the adjustment screw is rather cumbersome, and when performing displacement adjustment, the staff is required to repeatedly rotate the adjustment screw to achieve the purpose of shifting the stopper finger. This design greatly reduces the processing efficiency. Utility Model Content
