CN202516848U - Oil removal device for four-high cold rolling mill - Google Patents

Abstract

The utility model discloses an oil removal device for a four-high cold rolling mill. The device comprises wool felts, supporting rollers, working rollers, springs, bearing pedestals, pull rods, a compressed air pipe and an air knife, wherein the wool felts are arranged on the upper and lower supporting rollers respectively; one end of each spring is fixed on one bearing pedestal, and one side of the other end of each spring is connected with one wool felt through one pull rod; the compressed air pipe is arranged on one side of each of the working rollers; the air knife is arranged at the tail end of the compressed air pipe; and a knife edge points to a gap between the upper and lower working rollers. According to the device, the wool felts are arranged on the upper and lower supporting rollers, so that a coolant at an inlet cannot be brought to an outlet side; and the gap of the working rollers is purged by compressed air through the air knife, and the air pressure is adjusted to ensure that rolling oil at the gap of the working rollers is dispersed toward two ends and does not fall on a strip, so that the aim of removing residual oil at the gap of the working rollers is fulfilled.

Description

The 4-roller cold rolling mill degreasing unit

Technical field

The utility model relates to a kind of degreasing unit of 4-roller cold rolling mill in the copper strip operation of rolling.

Background technology

In the copper strip operation of rolling, cold press oil removing problem is to perplex a great problem of respectively oppressing producer always.

Because the rolling oil removing of copper strip not to the utmost, causes the consumption of a large amount of rolling mill compounds, mill speed is not high, but also because of strip surface speckles with greasy dirt, makes strip surface produce oil mark, influences the strip surface quality.How to solve this difficult problem, do not appear in the newspapers.

Summary of the invention

The purpose of the utility model be provide according to actual needs a kind of in band (like copper strip) production process a kind of degreasing unit of 4-roller cold rolling mill.

The structure of the utility model comprises: wool felt, backing roll, working roll, spring, bearing block, pull bar, compressed air hose, air knife.

On two backing rolls, spring one end was fixed in bearing block about wool felt was installed in respectively, and the other end one side links to each other with wool felt through pull bar, and compressed air hose is contained in a side of working roll, and its end is equipped with air knife, and the edge of a knife points to the seam place between the double-working up and down.

Be slowly to move rolling band between the double-working, cooling fluid gets into the double-working seam from the opposite direction that the compressed air hose air knife points to, and compressed air purges to work roll gap place through air knife.

The beneficial effect of utility model is: wool felt is installed propping up up and down on the roller, is made the inlet cooling fluid can't be brought into that side of outlet; Purge because work roll gap place is carried out air knife compressed air, and adjust air pressure, the ROLLING OIL at work roll gap place is scattered to two ends, do not drop on strip, thereby reach the purpose of removal work roll gap place Residual oil.

The specific embodiment

The structure of the utility model comprises: wool felt, backing roll, working roll, spring, bearing block, pull bar, compressed air hose, air knife.

On two backing rolls, spring one end was fixed in bearing block about wool felt was installed in respectively, and the other end one side links to each other with wool felt through pull bar, and compressed air hose is contained in a side of working roll, and its end is equipped with air knife, and the edge of a knife points to the seam place between the double-working up and down.

Be slowly to move rolling band between the double-working, cooling fluid gets into the double-working seam from the opposite direction that the compressed air hose air knife points to, and compressed air purges to work roll gap place through air knife.
