Abstract

The utility model provides a universal rolling mill vertical roll device which is characterized by comprising a vertical roller, cylinder axletrees, a thrust axletree and a mandrel. The vertical roller is fixed on the mandrel through the cylinder axletree and the thrust axletree, a distance ring is arranged between a double-rib inner sleeve of an upper cylinder axletree and a double-rib inner sleeve of a lower cylinder axletree, and a shaft washer of the thrust axletree is fixed between an upper distance ring and a lower distance ring. Two races are fixed between an outer sleeve of the upper cylinder axletree and an outer sleeve of the lower cylinder axletree, an upper gland and a lower gland are fixed on the vertical roll to press the outer sleeves of the cylinder axletrees, and a framework seal ring is arranged between the outer side of a transparent cover and the inner side of the gland to form an integrated universal rolling mill vertical roll device. The universal rolling mill vertical roll device has the advantages of being highly universal, simple in processing and manufacture, flexible in installing, convenient to use and adjust, stable in controlling rolled piece, and capable of bearing much roll force, and avoiding production equipment accidents such as damages of the vertical roll axletree and cracking of vertical roll in production, reducing production accidents such as dropping rolling materials, waste materials and pilling-up of steel and improving products quality.

Description

The universal rolling mill vertical roll device

Technical field

The utility model 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 by the hot steel billet that conticaster is produced, is carried by roller-way in the production process of H shaped steel, and heat is delivered to walking beam heating furnace, with heating steel billet to 1100 ℃-1150 ℃.Through dephosphorize by high pressure water, to reversible roughing mill, reversible rolling 3-7 passages were rolled into nearly end form section to steel billet through roller transport after steel billet was come out of the stove.Before by roller-way rolled piece being transported to flying shear, by detecting, flying shear carries out automatic crop, and the rolled piece behind the crop enters the universal mill tandem rolling, and to carry out final molding rolling.Rolled piece after the moulding is transported to cold bed to carry out below the whole total length cooling down to 70 ℃, then carry out the total length aligning through straightener, finished product rolled piece behind the aligning is organized into groups in a row, grouping entered the cold saw district after rolled piece was in a row through marshalling, 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, automatically falls to piling up neatly packing according to relevant regulations, 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 when rolling; core technology verticle roll unit wherein is owing to being subjected to the restriction of structure space; bear again simultaneously the very large roll-force effect of H section steel flange flow of metal; 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 edger roll damage of bearings and edger roll cracking often can occur aborning; occur falling to roll in a large number material and waste product; even cause and pile the steel production accident; bearing and edger roll consumption increase; affected product quality; qualification rate and volume recovery have been reduced; increase production cost, affected the economic benefit of enterprise.

Summary of the invention

The utility model has overcome the defective of above-mentioned existence, and purpose is for solving metallurgy industry on the H type steel production line, and universal mill can be stablized the control rolled piece when hot rolled H-shaped, bears larger roll-force, and a kind of universal rolling mill vertical roll device is provided.

The summary of the utility model universal rolling mill vertical roll device context:

The utility model universal rolling mill vertical roll device is characterized in that: be to be made of edging roll, cylindrical bearing, thrust bearing, mandrel four parts, cylindrical bearing is made of two rib inner sleeves, overcoat and the cylinder rolling element that is arranged in two rib inner sleeves and the overcoat; Thrust bearing is to be made of seat ring and the blowout patche and the circular cone rolling element that are arranged in the seat ring; Edging roll is fixed on the 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 the mandrel by sunk screw, push down two rib inner sleeves of cylindrical bearing, on, lower two glands are fixed on the edging roll by dormant bolt, push down the overcoat of cylindrical bearing, backbone sealing ring is arranged between the transparent cover outside and the gland inboard.

The utility model universal rolling mill vertical roll device, 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.
