A multi-station transfer press (10) is provided. Cross bar assemblies (28) transfer work pieces (12) between adjacent press stations (14) in transfer press (10). Each cross bar assembly (28) moves work pieces (12) between adjacent press stations (14). Motions of cross bar assemblies (28) is provided by raising and lowering transfer rails (22) and (24) along with reciprocating cross bar assemblies (28) along transfer rails (22) and (24). Cross bar assemblies (28) are operable to dynamically orient work pieces (12) during transfer between adjacent press stations (14). Additionally, a portion of the motion of cross bar assemblies (28) occurs while upper dies (20) and lower dies (18) are separated by less than a maximum distance.
L'invention concerne une presse-transfert à postes multiples (10). Des ensembles de barres transversales (28) transfèrent les pièces à usiner (12) entre les postes (14) adjacents dans la presse-transfert (10). Chaque ensemble de barres transversales (28) assure le déplacement des pièces à usiner entre les multiples postes adjacents. Les mouvements des ensembles de barres transversales sont assurés par le soulèvement et l'abaissement de rails de trasfert (22) et (24) par le va-et-vient de barres transversales (28) le long des rails de transfert (22) et (24). Les ensembles de barres transversales (28) peuvent être actionnés pour orienter dynamiquement les pièces à usiner (12) lors de leur transfert entre les postes (14) adjacents de la presse. En outre, une partie du déplacement des ensembles de barres transversales (28) se produit lorsque la distance séparant les matrices supérieures (20) des matrices inférieures (18) est inférieure à une valeur maximale.
