Title: Heat staking head with radiant heat source

Abstract: A head for use in a heat staking machine utilizes an infrared heat lamp and reflectors to direct radiant energy onto a plastic stud to heat and so soften it prior to the staking punch impacting the stud. The lamp is disposed within a parabolic primary reflector which directs the lamp's output toward a secondary reflector. The secondary reflector has is concave and has a central aperture at its vertex through which the stud projects such that all of the radiant energy emitted by the lamp is focussed radially inward onto the stud. The punch is slidably mounted to the primary reflector for reciprocal movement along the axes of the reflectors, and is extended to impact the stud.
