Abstract
FIELD: extrusion of hollow products. SUBSTANCE: apparatus has the frame 1, the ram 2, the mandrel 3, the container 4, the hydraulic cylinder 7 for moving the container 4, the hydraulic cylinder for moving the mandrel, the press-plunger 8, having a cavity, filled by a liquid, the die 11. The cavities of the plunger 8 and the hydraulic cylinder 7, mutually connected by a pipeline with a double-position spool, have the same diameters. The mandrel has profiled end portion and a mean portion with a different profile. The blank 15 is being placed on the ram 2, and upon motion of the plunger 8 it is being reduced in the die along the end portion of the mandrel 3, being moved in synchronism with the die 11. The cavities of the plunger 8 and the hydraulic cylinder are mutually disconnected by the closed spool. When the cavity of the product is connected with the end portion of the mandrel 3, the spool is being switched over, and liquid from the cavity of the plunger 8 flows to the cavity of the hydraulic cylinder 7. Then the mandrel is being moved more rapidly, than the blank to the same side for providing high-quality shaping of a second cavity and of a transition part between them. EFFECT: enhanced quality of hollow products. 1 cl, 2 dwg
