Preferably, the first motor rotates the first lead screw through belt transmission, and the second motor rotates the second lead screw through belt transmission.
Preferably, the cutter unloading cylinder is positioned above the receiving cylinder.
According to the technical scheme, the utility model has the beneficial effects that:
the matched knife device can horizontally move on the pressing device of the plate bending workbench, the matched knife device can detach and support the pressing knife from the pressing device, and can drive the detached pressing knife to vertically move horizontally and vertically, so that the matched knife device can automatically detach one pressing knife from a certain position of the pressing device, then the pressing knife moves longitudinally and leaves a whole row of pressing knives, and then the pressing knives are properly lifted vertically to drive the pressing knives to transversely move to another position of the pressing device for replacement, thereby reducing manual knife changing operation, improving the efficiency of matched knives, having simple and reliable structure, saving manpower and reducing cost.
