Abstract

The invention relates to a vertical roller device of a universal rolling mill. The vertical roller device is characterized in that the vertical roller device is composed of four portions including a vertical roller, cylindrical bearings, a thrust bearing and a mandrel, the vertical roller is fixed on the mandrel through the cylindrical bearing and the thrust bearing, spacer rings are arranged between double-flange inner sleeves of the upper cylindrical bearing and the lower cylindrical bearing, shaft rings of the thrust bearing are fixed between the upper spacer ring and the lower spacer ring, two seat rings are fixed between outer sleeves of the upper cylindrical bearing and the lower cylindrical bearing, an upper gland and a lower gland are fixed on the vertical roller and presses the outer sleeves of the cylindrical bearings, and framework sealing rings are arranged between the outer sides of transparent covers and the inner sides of the glands to form the integral-type vertical roller device of the universal rolling mill. The vertical roller device has the advantages of high universality, simplicity in processing and manufacturing, flexibility in mounting, convenience in use and adjustment, stability in rolled piece control and capability of bearing bigger rolling force, production equipment accidents like damage to a vertical roller bearing and cracking of the vertical roller in the process of rolling production can be avoided, production accidents like falling of rolling materials, waste products and steel piling are reduced, and product quality is improved.

Description

The universal rolling mill vertical roll device

Technical field

The present invention relates to the shaped steel production technical field, particularly a kind of hot rolled H-shaped special equipment universal rolling mill vertical roll device.

Background technology

At present, domestic metallurgy industry is in the production process of H shaped steel, and the hot steel billet of being produced by conticaster, carry by roller-way, and heat is delivered to walking beam heating furnace, by heating steel billet to 1100 ℃-1150 ℃.Steel billet come out of the stove after through dephosphorize by high pressure water, steel billet is through roller transport to reversible roughing mill, reversible rolling 3-7 passages, be rolled into nearly end form section.Before by roller-way, rolled piece being transported to flying shear, by detecting, flying shear carries out automatic crop, and the rolled piece after crop enters the universal mill tandem rolling and carries out the final molding rolling.Rolled piece after moulding is transported to cold bed to carry out below whole total length cooling down to 70 ℃, then carry out the total length aligning through straightener, finished product rolled piece after aligning is organized into groups in a row, rolled piece grouping after organizing into groups in a row enters the cold saw district, carry out the standard scale or carry out cold sawing according to user's requirement, the finished section bar of scale enters and automatically falls to piling up neatly bagging area, according to relevant regulations, automatically falls to piling up neatly packing, put in storage after the spray sign, finally mail to the user.In the production process of H shaped steel, to use the special equipment universal mill of producing H shaped steel during rolling, core technology verticle roll unit wherein is due to the restriction that is subject to structure space, bear again the very large roll-force effect of H section steel flange flow of metal simultaneously, therefore the structural design difficulty is very large, therefore verticle roll unit can become a weak link of the whole H type steel production line of restriction, the production equipment accident that often there will be aborning edger roll bearing damage and edger roll cracking, occur falling to roll in a large number material and waste product, even cause the production accident of heap steel, bearing and edger roll consumption increase, affected product quality, qualification rate and volume recovery have been reduced, increased production cost, affect the economic benefit of enterprise.

Summary of the invention

The present invention has overcome the defect of above-mentioned existence, and purpose is that when hot rolled H-shaped, universal mill can be stablized the control rolled piece, bears larger roll-force, and a kind of universal rolling mill vertical roll device is provided in order to solve metallurgy industry on the H type steel production line.

Universal rolling mill vertical roll device context summary of the present invention:

Universal rolling mill vertical roll device of the present invention is characterized in that: be to consist of edging roll, cylindrical bearing, thrust bearing, mandrel four parts, cylindrical bearing consists of two rib inner sleeves, overcoat and the cylinder rolling element that is arranged in two rib inner sleeves and overcoat, thrust bearing is to consist of seat ring and the blowout patche and the circular cone rolling element that are arranged in seat ring, edging roll is fixed on mandrel by cylindrical bearing and thrust bearing, on, lower two spacer rings are arranged on, between two rib inner sleeves of lower two cylindrical bearings, the blowout patche of thrust bearing is fixed on, between lower two spacer rings, two seat rings of thrust bearing are fixed on, between the overcoat of lower two cylindrical bearings, on, lower two transparent covers are fixed on mandrel by sunk screw, push down two rib inner sleeves of cylindrical bearing, on, lower two glands are fixed on edging roll by dormant bolt, push down the overcoat of cylindrical bearing, backbone sealing ring is arranged between the transparent cover outside and gland inboard.

Universal rolling mill vertical roll device of the present invention, have that sharing nature is strong, processing and manufacturing is simple, use characteristics easy to adjust, flexible for installation, that larger roll-force is stablized, can be born to the control rolled piece, can avoid the production equipment accident at the neutral roller bearing damage of Rolling Production and edger roll cracking, reduced and fallen to roll material, waste product and the production accident of heap steel, improve product quality, reduced production cost, improved qualification rate and the volume recovery of product.
