Abstract

The invention discloses a feeding angle adjusting device of a three-roller skew rolling mill, which solves the problem of the prior art that the adjustment of the feeding angles of three rollers cannot be synchronized with the same accuracy. The feeding angle adjusting device comprises a dual-output shaft driving motor (6) and three worm lifts, wherein the dual-output shaft driving motor (6) and the three worm lifts are fixed on a frame (1) respectively; the dual-output shaft driving motor (6) is connected with the input shafts of the three worm lifts through three couplings in turn respectively; the three worm lifts are connected with three drum devices through respective swing bars and hinges respectively; and three sets of swing devices synchronously swing in set directions. According to the invention, synchronous and centralized adjustment of the feeding angle of the three-roller skew rolling mill can be realized.

Description

technical field [0001] The invention relates to a rolling mill equipment for hot-rolling seamless steel pipes, in particular to a feeding angle adjustment device for a three-roll skew rolling mill. Background technique [0002] The feed angle adjustment of the existing open-frame three-roll skew rolling mill is to adjust the three rolls separately, and the rolls installed in the frame are adjusted by three sets of independent lead screw adjustment mechanisms. This structure has the technical problem that the adjustment of the feeding angles of the three rolls cannot be carried out synchronously and with the same precision, so that the rolling precision of the waste tube is low, and waste products often occur. Contents of the invention [0003] The invention provides a feed angle adjustment device for a three-roll skew rolling mill, which solves the problem in the prior art that the adjustment of the feed angles of the three rolls cannot be carried out synchronously and wit...
