CA 2230271

A quick change tooling method and apparatus has been devised for tube bending operations in which the bend die (34), clamp die (35) and pressure die (36) as well as mandrel and wiper die (37), if required, are preassembled along with a tube corresponding to the tube to be bent in that particular die assembly by releasable latches (52, 54) or other types of releasable connectors; and each preassembled die set as described can be removed, transported and relocated on a bending machine (10) as a complete assembly and in exact aligned operating position without readjustment. A lift mechanism (84) is provided to facilitate lifting of each die set.

L'invention concerne un procédé et un appareil pour outillage à changement rapide, destinés à des opérations de cintrage de tubes dans lesquelles l'outil de cintrage (34), l'outil de serrage (35) et l'outil de pression (36) ainsi que le mandrin et l'outil de planage (37), le cas échéant, sont pré-assemblés conjointement avec un tube correspondant au tube à cintrer dans ce bloc d'outils particulier, par des systèmes de blocage libérables (52, 54) ou bien d'autres types d'éléments de raccordement libérables; et chaque bloc d'outils pré-assemblés peut être démonté, transporté et remonté sur une machine de cintrage (10) sous forme d'ensemble complet et en position de fonctionnement parfaitement alignée sans nouveau réglage. Un mécanisme de levage (84) est prévu pour faciliter le levage de chaque bloc d'outils.
