Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically a cold rolling mill for steel bar processing. Background Technology

[0002] A cold rolling mill is a new type of equipment for cold rolling steel bars. Cold-rolled ribbed steel bars produced by a cold rolling mill are a replacement for cold-drawn low-carbon steel wire in prestressed concrete components. In cast-in-place concrete structures, they can replace Grade I steel bars, saving steel and making them one of the better types of cold-worked steel. However, cold rolling mills require processing the steel during rolling to remove surface oxides and impurities. Existing cold rolling mills typically use repeated bending for this process. After this, work hardening increases the hardness and brittleness of the steel, hindering subsequent processing. Furthermore, there is no suitable cutting mechanism to cut the steel after cold rolling. Utility Model Content

[0003] The purpose of this utility model is to provide a cold rolling mill for steel bar processing, which cleans the surface of steel by setting a cleaning brush and a de-irritation roller, and simultaneously sets a cutting component to cut the rolled steel, thus solving the problem of cleaning oxidized impurities on the steel surface.

[0004] This utility model is achieved through the following technical solution:

Second bearings 706 are fitted inside the first bearing mounting holes 705. Impurity removal rollers 707 are fitted inside the two second bearings 706.

[0029] The cutting assembly 8 includes a servo motor 801, which is installed in a motor mounting hole 105. A drive gear 802 is fitted on the motor shaft at the output end of the servo motor 801.
