Inductor material sheet production die

The utility model relates to the technical field of inductor material sheet processing, in particular to a die for producing material sheets for inductors. The punching device comprises a positioning hole punch, a round hole punch and a frame punch which are arranged in the material sheet feeding direction. The positioning hole punches are symmetrically arranged along the middle line in a 2 * 8 mode, the round hole punches are arranged on the middle line in a 1 * 8 mode, and the machining positions of the round hole punches on the material sheet correspond to the machining positions of the positioning hole punches; and the position of the frame punch corresponds to the processing position of the round hole punch. The technical scheme has the beneficial effects that by designing the eight-hole stamping die, the original one-die six-hole mode is changed into the eight-hole mode, the efficiency is improved by 25%, and the production cost is reduced; in the subsequent integrally-formed inductor manufacturing proc
