Forming method for cutting edge of shutter punch of air conditioner die

The invention discloses a forming method for a cutting edge of a shutter punch of an air conditioner die. A plurality of punching teeth are arranged on the cutting edge at intervals, the punching teeth on the two sides are in mirror symmetry, the number of the punching teeth on the single side is m, and the distance between the punching teeth is X. The forming method comprises the steps that corresponding grinding teeth are designed on a grinding wheel profile according to the shapes of the punching teeth on the cutting edge, at least one pair of grinding teeth are arranged in a mirror image manner; a formed grinding wheel with a target profile is trimmed through a diamond pen; and the surface of a punch block is directly ground by the forming grinding wheel, grinding is carried out in several times, the grinding wheel transversely deviates by the Y distance relative to the punch block every time, and therefore the target cutting edge shape is formed. According to the forming method for the cutting edge of th
