ABSTRACT:
A mechanical transfer press employs a plurality of paired self-supporting, stroke doubling transfer/feed mechanisms, with each pair of transfer/feed mechanisms coupled to a cross bar, for sequentially transferring piece parts to a series of stamping stages in the press. Vacuum cups attached to the cross bar engage one or more piece parts for transferring the piece parts to the next stage. Each transfer/feed mechanism includes a lift/lower drive as well as a feed/return drive for positioning piece parts intermediate upper and lower dies of the press and for removing the cross bar and vacuum cups from the stamping stage prior to the stamping operation. Each pair of transfer/feed mechanisms is positioned above its associated stamping stage to facilitate access to and increase clearance from the dies. Each pair of transfer/feed mechanisms with its associated dies forms a press module which can be easily removed and replaced as well as individually adjusted in its feed/return and lift/lower distances and motion profile independent of other such modules. A programmable numeric controller is used to control press as well as transfer/feed mechanism operation.
