The invention provides an integrated rotary cutting device. The integrated rotary cutting device comprise a wire material extrusion die, a field coil (4), a first carrier (2), a transmission component (37) and a cutter mechanism (5). The first carrier (2) is arranged on the outer side of a guide mouth (6) of the wire material extrusion die. Being driven by the field coil (4), the first carrier (2) drives the whole cutter mechanism (5) or part of the cutter mechanism (5) to rotate through the transmission component (37), so that the cutter mechanism (5) conducts cutting in a discharging area on the outer side of the guide mouth (6). According to the integrated rotary cutting device, a wire material cutting-off unit and the wire material extrusion die are integrated, so that the structure is reasonable and compact. The integrated rotary cutting device is a fast real-time wire material shearing device, and according to the die, the function of controllable wire material cutting-off is achieved while extrusion wire materials are extruded from an outlet of the die.
