Steel plate cold rolling mill

Abstract

The invention provides a steel plate cold rolling mill. The steel plate cold rolling mill can carry out large driving force transmission, and a transmission mechanism of the steel plate cold rolling mill is simple in structure and not easy to damage. The steel plate cold rolling mill comprises a left wallboard and a right wallboard, wherein bearing blocks are arranged on the inner side of the leftwallboard and the inner side of the right wallboard; the two ends of a first shaping roller and the two ends of a second shaping roller are installed in the bearing blocks of the wallboards on the two sides; the first shaping roller and the second shaping roller both comprise an upper pressing roller and a lower pressing roller, and every two pressing rollers are provided with protrusions and grooves which are correspondingly formed; the upper pressing rollers and the lower pressing rollers of the first shaping roller and the second shaping roller are driven by two sets of chain transmissionmechanisms respectively. The two sets of chain transmission mechanisms are driven by two driving motors and do not influence each other, and it is guaranteed that the driving force is large; meanwhile, the reverse direction operation of the upper pressing rollers and the lower pressing rollers of the shaping rollers is very convenient. The steel plate cold rolling mill is simple in structure and does not have complex mutual connection conditions; the large driving force can be ensured by two driving mechanisms, the rotating directions of the two driving mechanisms are opposite, and cold rolling extrusion of steel plates is achieved.

Description

technical field [0001] The invention relates to cold rolling equipment, in particular to a cold rolling mill, which is applied to cold rolling of steel plates. Background technique [0002] Cold rolling mill is a new type of steel cold rolling processing equipment. This machine can process hot-rolled discs and steel coils into finished products, and then carry out subsequent production. In some cold-rolling processes, the steel plate needs to be cold-rolled, and a special structure needs to be cold-rolled on the steel plate; ), station scales, box blocks, etc. After cold-rolling the formed materials, they will be combined and welded into the railing of the truck compartment. [0003] When the traditional cold-rolling mill cold-rolls the corrugated plate of the car railing, because it requires a large cold-rolling force, it is necessary to set up multiple motors and reduction mechanisms to drive the bearing roll and work roll in the shaping roll to rotate, and the steel pla...

AI Technical Summary

Problems solved by technology

At present, there is also a cold rolling mill structure, which uses one motor and reduction mechanism, and then realizes the reverse movement of the bearing roll and work roll in the calibrating roll through the transmission of sufficient chain gears and gear pairs. This structure is more complicated. , easy to damage, and its overall driving force is still less than the driving mode of multiple motors and reduction mechanisms
