FLUID-DRIVEN FORMING EXTRUDER Russian patent published in 2014 - IPC B30B1/32 B30B11/26 B21C23/21 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming. Proposed extruder comprises frame-type composite bed supporting crossbar with ram assy and hydraulic cylinders, piercing crossbar and fixed crossbar. Said fixed crossbar carries horizontally displacing table with die tooling and table for female die units with piercing and die tooling. Container holder with container is arranged between moving crossbar and said tables to displace vertically there between. Container holder is displaced by hydraulic drive composed of two piston-type hydraulic cylinders secured at fixed crossbar on both sides of the tables. Container holder comprises two stationary units and replaceable unit. Every stationary unit is rigidly secured at appropriate hydraulic cylinder piston. Replaceable units is arranged between stationary units, its axial position being adjusted by wedges.

EFFECT: higher reliability and precision of extruded articles.
