ABSTRACT:
An extrusion press having a die slide assembly capable of shearing the extrusion in the die, and transporting the die to a side movable transfer table for change thereof, the assembly eliminating excessive projection beyond the confines of the extrusion press of die transport equipment. The die slide assembly includes a first hydraulic cylinder for shearing an extrusion from the die, and a second hydraulic cylinder mounted adjacent the first cylinder for transporting the die and die holder to a transfer station on the side of said platen, permitting an exchange of the die holder die therewith, when necessary. The second hydraulic cylinder is movable with the die slide assembly to minimize the length requirements of the second hydraulic unit and still effectuate full traverse of the die holder.
