TRANSFER DEVICE IN A TRANSFER PRESS OR SIMILAR METAL- FORMING MACHINE

摘要

A transfer device permits different moving sequences of holding devices for sheet metal parts which are to be moved through a metal-forming machine. The holding devices are fastened to carriages. The carriages are cam-guided, in which case carriage carries out a transfer movement from a working stage to an idle stage while taking along a sheet metal part. The return movement is interrupted in an intermediate position during the deforming operation of the sheet metal parts. The carriage carries out a transfer movement from the idle stage to a working stage and a return movement which is temporarily interrupted in an intermediate stage. As a result of the low-mass construction of carriages, high accelerations are possible in the movements. The transfer movements are shortened significantly by the use of intermediate depositing devices in the idle stages.
