  • Patent number: 4520643
    Abstract: The assembly for blowing out and spraying dies in a forging press is particularly adapted both to automatically operating and hand operated drop-forging presses. The automatically operating drop forging presses have workpiece transport effected by a walking beam transport system. The blowing and spraying assembly comprises arms having nozzles disposed at the end thereof to be guided into the mold area of the forging press in a timed sequence while avoiding the movement of the press plunger and walking beam transport system when it is being used. The blowing and spraying assembly comprises a carrier means hinged to a four-bar linkage arrangement which has two levers and a carrier member. In a specific embodiment, the ends of the two levers facing away from the carrier member are pivotably mounted to a housing. The housing constitutes a carrier support means secured to the stator of the forging press.

The hinged quadrilateral mechanism is driven by a crank gear assembly and includes one fixed side portion and two hinged side portions movably mounted to the fixed hinged side portion. The pincer assembly is rotatably connected to the free ends of the movable hinged side portions. Each of the movable hinged portions include a lever member with one of the lever members being longer than the other lever member. The longer lever member is rotatably connected to a front portion of the pincer assembly.
