High-speed steel bar cold-rolling mill

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of cold rolling mill equipment, in particular to a high-speed steel bar cold rolling mill. Background technique [0002] Cold rolling mill is a new type of steel cold rolling processing equipment. The machine can process hot-rolled wire rods and hot-rolled coils with diameters between 6.5 mm and 12 mm into cold-rolled ribbed steel bars with diameters between 5 mm and 12 mm. The cold-rolled ribbed steel bar rolled by a cold rolling mill is an updated product of cold-drawn low-carbon steel wire in prestressed concrete members. In cast-in-place concrete structures, it can replace grade I steel bars to save steel. It is one of the better cold-worked steels of the same kind. If speed regulation is not required during the rolling process of the cold rolling mill, an AC motor can be used; if speed regulation is required during the rolling process of the cold rolling mill, a DC motor can be used.
