PURPOSE: A reverse cam unit is provided to prevent the separation of a cam operating unit from a casing during an interlocking process by a cam action for interlocking a cam drive, a cam slide, and the cam operating units according to the operation of a press mold operating unit. CONSTITUTION: A reverse cam unit comprises a casing(10), a cam drive(20), a cam slide, and a cam operating unit(40). The cam drive corresponds to the bottom of an operating unit, vertically moves in one side inside the casing, and is equipped with an inclined slide unit with the bottom end. The cam slide is combined with the bottom of the inclined slide unit. The cam slide unit comprises triangular slide units with both top sides in order to be transferred to the other side inside the casing by corresponding to the descending action of the cam drive according to the impact of the operating unit. The cam operating unit comprises an inclined slide unit. The inclined slide unit is vertically transferred by the cam action with the cam slide, lifts a forming punch and a piercing punch which are fixed to the front top end, and processes a material which is fixed to the top and bottom die of the press mold. |
