ABSTRACT:
Improvement in a punch, anvil and die set for spot clinching two or more materials together to form a spot clinch joint in which the anvil is arranged inside of the die and the punch and die move toward and away from each other and a lancing operation occurs on a workpart followed by a swaging operation in which the die spreads apart to accommodate the radial enlargement of the material of the workpart being swaged, the improvement comprising the die having a rigid base having an aperture therein, the anvil disposed in the aperture, an arrangement for adjusting the axial position of the anvil relative to the die to accommodate different thicknesses of workparts, the die having resilient fingers which upstand from the base, the die fingers, in themselves, providing both the strength to support the workpart to effect the lancing operation and the resiliency to separate from the front end of the anvil during the swaging operation, the die and anvil normally engaged at both their front and rear ends and spaced from each other between the ends, the spaces extending axially between the die fingers and the anvil and serving to prevent foreign matter from hindering return of the die fingers to their closed position following the swaging operation.
