High-speed steel bar cold-rolling mill

The invention discloses a high-speed steel bar cold-rolling mill, and relates to the technical field of cold-rolling mill equipment. The high-speed steel bar cold-rolling mill comprises a feeding mechanism, conveying mechanisms, four cold rolling mechanisms and a cold rolling supporting frame; the feeding mechanism is horizontally arranged; the cold rolling supporting frame is vertically arranged at the side end of the feeding mechanism; the four cold rolling mechanisms are sequentially installed on the cold rolling supporting frame in a linear mode; the distances between the rollers in the four cold rolling mechanisms are gradually decreased from bottom to top, and the conveying mechanisms are distributed on the two sides of the cold rolling supporting frame. Steel bars are driven by the conveying mechanisms to pass through the multiple cold rolling mechanisms, the cold rolling mechanisms are arranged to be the up-down mechanisms, and therefore the occupied area of the steel bar cold rolling equipment is reduced.
