Punch apparatus develops momentum of a desired magnitude. The momentum is transferred to a punch for driving the punch from a reset position to a punch position.

Punch apparatus

A punch station for punching ceramic green sheets comprises a magnet plate and two flux guide plates to form the flux field within which a coil of wire resides and acts to cause the punching movement of a punch. The magnet plate allows the placement of adjacent punch stations more closely together than is possible when cylindrical magnets are used since the magnetic material lying between the punch being activated and the punches surrounding the activated punch has an additive effect and produces a more dense flux field than achievable with the cylindrical magnets. The flux guide plates concentrate the flux from the magnet plate into a small gap further increasing flux density in the working gap. The magnet plate overcomes the losses inherent with magnets separated by air gaps.
