CONTINUOUS EXTRUSION APPARATUS Russian patent published in 2001 - IPC

FIELD: plastic metal working by continuous extrusion. SUBSTANCE: apparatus for continuous extrusion includes rotating wheel with annular groove. Outer in radial direction portion of groove is restricted by arc-shaped tool having outlet opening in attachment of die and stop assembly. The last is restricted by bearing surface formed by tenon and designed for engaging with cylindrical surface of wheel and with flat surface parallel and shifted relative to plane passing through wheel axis and spaced from bearing surface. Said flat surface is arranged in such a way that it may engage with reciprocal surface of wedge-shaped recess in attachment of die. Tenon has lateral shoulders. Flat surface joined with recess is arranged in such a way that effort component created on bearing surface for displacing fed material from annular groove towards outlet opening acts in direction for embedding stop assembly into wedge-shaped recess at rotation of wheel. EFFECT: minimized leakage volume of fed material, simplified less-cost operation for changing stop assembly of apparatus. 7 cl, 5 dwg
