APPARATUS FOR THE TRANSFER OF WORKPIECES IN A MULTISTAGE PRESS FOR THE COLD DEFORMATION BY MEANS OF COLD EXTRUSION AND THE LIKE

摘要

A multistage press for the cold deformation of workpieces comprising a first and second opposing toolholders capable of reciprocating relative to each other by the distance therebetween is disclosed which is characterized by an apparatus for transferring the workpieces from one working station to the next and permitting bilateral deformation of the workpieces. The apparatus comprises a plurality of die recesses in each of the said toolholders, the first toolholder having a greater number of die recesses than the second toolholder; means to displace the first toolholder laterally with respect to the second toolholder; means to displace the second toolholder longitudinally with respect to said first toolholder; ejector means associated with each die recess in the two toolholders; and an ejector press in operative communication with the ejector means and being coordinated with the deformation press to alternately transfer the workpieces from one toolholder to the other.
