Abstract

The utility model discloses a novel roll system of a four-roll cold-rolling mill, comprising an edge chamfer bearing roll I, an edge chamfer bearing roll II, a working roll I, a working roll II, and a bearing seat, wherein rolled plates pass through between the two working rolls, the edge chamfer bearing roll I and the edge chamfer bearing roll II are arranged above and below the two working rolls, and all the edge chamfer bearing rolls and all the working rolls are fixed on the bearing seat. The roll system of the four-roll cold-rolling mill uses an edge chamfer bearing roll structure, and the roll surfaces of the bearing rolls during a process of rolling strips of the roll system of the four-roll cold-rolling mill cannot drop chippings and separate off, so that the service life of the roll system can be prolonged, and the plate shapes of the strips can be improved simultaneously.

Description

A kind of novel 4-roller cold rolling mill roller is

Technical field

The novel 4-roller cold rolling mill roller that the utility model relates to a kind of rolled copper slab material is.

Background technology

In rail system copper coin material was produced, traditional four roller cold press backing roll roll shapes were plain-barreled roll or recessed roller, and two side cylinders produce active force to back-up chock when rolling; The pressure of working roll roll surface both sides portion is greater than the pressure at middle part when depressing; Cause the roll surface unbalance stress, and using a period of time rolling district roll surface low water, the stressed increasing of roll surface limit portion; Cause backing roll limit portion appearance piece to come off, cause backing roll to be scrapped.

Summary of the invention

The purpose of the utility model is that the defective that is directed against prior art provides a kind of cold trailer roller of four rollers system that improves roll shape.

The embodiment of the utility model is with backing roll both sides portion chamfering, and roll surface is approaching or equal strip width, changes backing roll and the effective contact-making surface of working roll, reduces roll surface limit portion pressure, increases middle part pressure, improves the present situation of roll surface unbalance stress.

The structure of the utility model comprises: limit portion chamfering backing roll one, limit portion chamfering backing roll two, working roll one, working roll two, bearing block;

Pass through rolled plate between the double-working, the upper and lower limit portion chamfering backing roll one and the limit portion chamfering backing roll two of being provided with of double-working, all limit portion chamfering backing rolls and working roll all are fixed on the bearing block.

The beneficial effect of the utility model is: adopt limit portion chamfering supporting roller structure, the 4-roller cold rolling mill roller ties up in the rolled strip process backing roll roll surface and does not fall piece and come off, and can increase the service life, and improves the band template simultaneously again.
