Tool-holder for a metal-forming machine tool like a forging machine has a supporting body forming a retaining device for using a metal-forming tool with a positive fit and clamping pieces on the supporting body to lock into recesses

摘要

Impinged with a spring like a clamp, clamping pieces (5) fit on a supporting body (1) so as to swivel. A metal-forming tool (4) has slanted stopping faces (14) for locking the clamping pieces automatically into locking recesses (7), which form stopping faces slanted in an opposite direction (16) for automatic release of the clamping pieces from the locking recesses. Tension rods (12) are applied to the clamping pieces between their swiveling support on the supporting body and their locking catches (6) that engage into the locking recesses.
