Hobbing type reinforcing steel bar shredding cutter

The invention discloses a rolling cutting type reinforcing steel bar shredding cutter, and belongs to the technical field of cutters for machining. The hobbing type reinforcing steel bar shredding cutter comprises cutter shafts arranged side by side, circular blades and spacer bushes, the circular blades and the spacer bushes are fixed to the cutter shafts in a staggered mode, cutter teeth and cutter tooth grooves are arranged on the peripheral faces of the blades in a staggered mode, and the sections of the cutter teeth and the cutter tooth grooves in the horizontal direction in the axial direction where the cutter shafts are located are both in a trapezoid shape. In specific application, the cutter teeth, the cutter tooth grooves and the blade can be of an integrated structure or detachably fixed to the blade. By designing the cutter teeth with the trapezoidal cross sections in the horizontal direction of the axial direction where the cutter shaft is located, the effect of buffering type shearing and shredd
