Manufacturing method of double-edge drum cutter shaft

The invention relates to the field of flying shear equipment, in particular to a manufacturing method of a double-edge drum cutter shaft. Comprising the following steps: optimizing a cutter shaft hardening and tempering allowance graph: roughly slotting a shear blade mounting surface, wherein two end surfaces of a slot are not opened; quenching and tempering the workpiece shaft according to the optimized quenching and tempering allowance graph, so that the allowance meets the set requirement; a balancing weight is arranged, specifically, the balancing weight is machined according to the boundary dimension of the shear blade mounting face groove, and a configuration block is placed in the rotating body to restore the contour and the gravity center of the rotating body; the angle plate is arranged on the transmission side, and the axis of the auxiliary datum hole of the angle plate is corrected to be parallel to the machine tool shaft through a wire meter. The method solves the technical problems that after the
