Heat staking head with radiant heat source

A heat staking apparatus for deforming a thermoplastic part comprising:

• a cylindrical housing having an end cap defining a cavity into which at least a portion of the stud can be admitted;
• an energy source disposed in the housing and for generating energy in the infrared band;
• a primary reflector disposed in and fixed to the housing in surrounding relationship to the energy source for directing energy substantially axially of the housing;
• a secondary reflector affixed to the housing in axially spaced relation with the primary reflector to receive energy therefrom and to concentrate the energy on a defined treatment area essentially surrounded by the secondary reflector;
• said secondary reflector having an aperture found centrally therein to admit the stud into the treatment area;
• a punch mounted in the housing for movement toward and away from the stud;
• and
• a power means for selectively causing movement of the punch.

A heat staking apparatus for deforming a thermoplastic part comprising:

• a housing defining a cavity into which at least a portion of the part is admitted;
• an energy source including at least one incandescent lamp for generating energy in the infrared band and affixed to the housing;
• a primary reflector having a generally parabolic shape surrounding the lamp and directing the light toward a secondary reflector;
• the secondary reflector spaced from the primary reflector and including a central aperture and a plurality of connected curved sections wherein each curved section provides localized redirection of the light to a focal area at a different distance from the central aperture;
• a slidable carriage mounted on the housing and moveable along an axis toward and away from the part;
• a power means magnetically attached to the slidable carriage and for selectively moving the slidable carriage toward and away from the part;
• and
• a punch mounted on the carriage.
