Press-fitting die and press-fitting method for low-iron-loss back-twist buckle point laminated riveting rotor

The invention relates to the field of rotor press-fitting dies, in particular to a low-iron-loss back-twist buckle point laminated riveting rotor press-fitting die and a press-fitting method. The low-iron-loss back-twist buckle point laminated riveting rotor press-fitting die comprises a mounting frame; the skew mechanism is arranged on the mounting frame, is used for skewing a punching groove in the rotor punching sheet and limiting the skewed rotor punching sheet, and comprises a rotating assembly; the base plate is rotationally mounted on the mounting frame through a rotating assembly and is used for placing a rotor punching sheet to be pressed; the pressing plate is arranged on the rotor punching sheet after being placed; the feeding mechanism is arranged on the mounting frame and is used for conveying the rotor punching sheet to the base plate; the feeding mechanism comprises a feeding clamping jaw, a feeding table and a sliding assembly. The feeding table is used for placing a rotor punching sheet to be
