ABSTRACT:
An assembly of air heaters and reciprocally movable air driven staking tools is provided for use in the assembly of pieces using thermally softenable and pressure deformable studs. The air heaters and air driven staking tools are assembled in a supporting structure through which air is circulated to cool the staking tools to limit adhesion of hot softened material to the working face of each staking tool. The air heaters and air driven staking tools are individually selectable and controllable to meet the requirement of each workpiece to be hnot staked. The method of operating the hot staking assembly is also disclosed.
