Multi-station stamping die

The utility model discloses a multi-stage transforming mould that comprises an upper mould and a lower mould; wherein, the upper mould is provided with a mould frame; the mould frame bottom is provided with a former punch seat block; the former punches are arranged on the seat block around the same axial circumference; the former punch seat block is provided with a rotary punching head wheel plate above which a power transmission device is arranged; one side of the rotary punching head wheel plate toward the former punch is provided with a work protruding part. During the set pressing stroke, the rotary punching head wheel plate can only carry out an effective pressing movement on the former punch at the work protruding part. The new design of the utility model can realize the fixed shifting among various former punches through choosing the rotary punching head wheel plate; the mechanical method for shifting among various former punches effectively has overcame the limitation of the existing technique on manually direct changing the multiple former punches, and increased the automatic control level of the mould in the same kind, and promoted the production efficiency of the entire processing device.
