Manual and automatic integrated plate bending and shearing machine

The invention relates to a manual and automatic integrated plate bending and shearing machine, in particular to a plate bending and shearing machine. The manual and automatic integrated plate bending and shearing machine comprises a rack, a power source device, an upper die assembly, a lower die assembly and transmission connecting rod mechanisms achieving two strokes. The power source device is installed on the top of the rack, and the output end of the power source device is connected with the transmission connecting rod mechanisms. The two sets of transmission connecting rod mechanisms are symmetrically installed at the left end and the right end of the rack respectively, the transmission connecting rod mechanisms are connected with the upper die assembly, the lower die assembly is installed at the bottom of the rack, and the upper die assembly is matched with the lower die assembly to achieve bending and shearing of plates. In one-time reciprocating motion of the power source device, two-time bending and
