FIELD: process engineering.
SUBSTANCE: invention relates to the field of pipe-rolling production, more specifically, to cold-rolling mills for pipes of large dimension type. Pipe cold-rolling mill comprises frame with guides, working stand installed on them, movable power bed plate with support rails and geared racks, movable cassette, working rolls installed in it with master pinions, and also drive for reciprocal motion of stand. Movable cassette comprises replaceable gages with variable-section strands and feed-and-turn gaps. Variable-section strands are referenced to base plane of gages by variable reference angle that allows deploying gages with variable-section strands and feed-and-turn gaps within the limits of cassette work travel. To synchronise motion of movable power bed plate and cassette there is a double-arm lever connected by means of connecting rod and additional connecting rod with movable power bed plate and connecting rods of permanent length with movable cassette. Foundation con rods feature constant length.
EFFECT: higher quality of rolled pipes, simplified operation of mill, higher reliability and longer life.
