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.
Claims11
An infrared heat staking head mountable on a heat staking machine:
- a radiant heat source for generating radiant energy;
- a primary reflector positioned relative to the radiant heat source to direct a substantial portion of the radiant energy toward a workpiece;
- a secondary reflector having an aperture for receiving a portion of the workpiece therethrough, the second reflector positioned relative to the primary reflector to collect a substantial portion of the radiant energy directed by the primary reflector and focus said collected energy onto the portion of the workpiece projecting through the aperture;
- and
- a punch reciprocally movable with respect to the primary reflector along a punch movement axis aligned with the aperture to impact the portion of the workpiece projecting through the aperture.
An infrared heat staking head mountable on a heat staking machine:
- a radiant heat source lamp for generating radiant energy in the infrared range;
- a generally parabolic primary reflector positioned in surrounding relationship to the radiant heat source to direct a substantial portion of the radiant energy along an axis toward a workpiece;
- a generally parabolic secondary reflector positioned relative to the primary reflector to collect a substantial portion of the radiant energy directed by the primary reflector and focus said collected energy onto the workpiece;
- and
- a punch slidably engaged with the primary reflector for reciprocal movement along the axis to impact and deform the workpiece.
