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.
