Description

A kind of New Type of Cold Roller

Technical field

The utility model relates to cold-rolling process apparatus field, particularly a kind of New Type of Cold Roller.

Background technology

Roll is the strength member on steel rolling mill's rolling mill, utilize a pair or one group of roll rolls time the pressure that produces to roll stone roller steel.Dynamic And Static Loads when it mainly bears rolling, the impact of wearing and tearing and variations in temperature, roll divides hot roll and cold roll two kinds.In conventional cold roll, the material of working roll has 9cr, 9cr2,9crv, 8crmov etc., and cold roll requires surface hardening, and hardness is hs45-105; The material that hot roll is conventional has 55mn2,55cr, 60crmnmo, 60simnmo etc., and hot roll is used in cogging, slab, in the processing such as shaped steel.Roll bears powerful roll-force, violent wearing and tearing and heat fatigue impact, and hot roll at high temperature works, and allows the diameter in working unit amount to wear and tear, so do not require case hardness, only requires to have higher intensity, toughness and heat resistance.Cold roll generally needs long-time continuous firing, produces a large amount of heat in rolling process, and existing cold roll structure is single, surface is shiny surface, it mostly directly adopts cooling water to be sprayed onto cold roll surface and cools, and cooling effectiveness is low and cold roll surface cool uneven, affects performance.

Utility model content

The purpose of this utility model is the defect overcoming prior art, provides a kind of rational in infrastructure, cooling effectiveness is high, performance is good New Type of Cold Roller.

To achieve these goals, the technical scheme taked of the utility model is as follows:

A kind of New Type of Cold Roller, comprises roll body, is arranged on roll body two ends and is positioned at the roll shaft of same axis with roll body and is arranged on roll body two ends and is applied in the position-arresting disk of roll shaft being located roll body;

Described roll body upper outer surface is axially provided with two and is positioned at the axial diversion groove of roll body axis offside and is evenly arranged on the spiral stream guidance groove of roll body;

Described position-arresting disk is provided with two and matches and the through hole communicated with axial diversion groove;

Described position-arresting disk is positioned on described roll body by fixed retaining member.

As further improvement of the utility model, described roll body and roll shaft are cylinder; The diameter of described roll shaft is less than the diameter of described roll body.

Compared with prior art, the beneficial effect acquired by the utility model is as follows:

The utility model is a kind of novel cold roll, axial diversion groove and spiral stream guidance groove is provided with at roll body upper outer surface, cooling water enters in axial diversion groove by the through hole on the position-arresting disk at roll body two ends, along with the rotation of roll shaft, cooling water is flowed fast by spiral stream guidance groove, improve cooling effectiveness and the large cooling of cold roll surface cool scope is even, solve the cold roll temperature difference to cause contracting the inconsistent problem easy to crack that rises, extend the service life of cold roll, reduce maintenance frequency, lower production cost.The utility model is rational in infrastructure, easy to operate, failure rate is low, and the steel rolling performance using the utility model to produce is also better.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model;

Accompanying drawing 2 is the utility model A portion structure for amplifying schematic diagram;

Accompanying drawing 3 is the structural representation of the utility model position-arresting disk.

In the accompanying drawings:

1 roll body, 2 spiral stream guidance grooves, 3 position-arresting disks, 4 fixed retaining member, 5 roll shafts, 6 axial diversion grooves, 7 through holes.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed further describing is carried out to the utility model.

As illustrated in the accompanying drawings from 1 to 3, a kind of New Type of Cold Roller, comprise roll body 1, be arranged on roll body 1 two ends and be positioned at the roll shaft 5 of same axis with roll body 1 and be arranged on roll body 1 two ends and be applied in the position-arresting disk 3 of roll shaft 5 being located roll body 1, roll shaft 5 is for being positioned at bearing or actuating unit, realize freely rotating of roll body 1, the diameter of described roll shaft 5 is less than the diameter of described roll body 1, and roll shaft 5 is convenient to be installed to line shaft.The two ends of position-arresting disk 3 pairs of roll bodies 1 are carried out spacing, stabilized structure, and the phenomenon loosened can not appear in true roll body 1 in use.As preferably, the shape of roll body 1 and roll shaft 5 is preferably cylinder, and the cross section of cylinder is circular or is tangential on round polygon, and the shape of roll body 1 is more preferably cylinder.The diameter of position-arresting disk 3 is greater than the diameter of roll body 1, and convenient two ends position-arresting disk 3 being installed to roll body 1 are carried out spacing to roll body 1.Described roll body 1 upper outer surface is axially provided with two and is positioned at the axial diversion groove 6 of roll body 1 axis offside and is evenly arranged on the spiral stream guidance groove 2 of roll body 1, described axial diversion groove 6 is set to linear pattern, as further preferred, the width of rebate of described axial diversion groove 6 is the 1/18-1/12 of roll body 1 diameter, and the groove depth of described axial diversion groove 6 is the 1/30-1/20 of roll body 1 diameter; The horizontal section of described spiral stream guidance groove 2 is circular arc, be convenient to the quick flowing of cooling water, the width of rebate of described spiral stream guidance groove 2 is the 1/6-1/2 of axial diversion groove 6 width of rebate, and the groove depth of described spiral stream guidance groove 2 is not more than the groove depth of described axial diversion groove 6.Described position-arresting disk 3 is provided with two and matches and the through hole 7 communicated with axial diversion groove 6, and through hole 7 is the inlet port of cooling water.Described position-arresting disk 3 is positioned on described roll body 1 by fixed retaining member 4, and fixed retaining member 4 is preferably bolt, and position-arresting disk 3 and roll body 1 are provided with the hole of corresponding bolt, bolt by position-arresting disk 3 by screw-threaded coupling on roll body 1.Dismountable connected mode makes the convenience quick for installation of position-arresting disk 3, and stabilized structure, can not loosen easily simultaneously.The utility model is a kind of novel cold roll, axial diversion groove 6 and spiral stream guidance groove 2 is provided with at roll body 1 upper outer surface, cooling water enters in axial diversion groove 6 by the through hole 7 on the position-arresting disk 3 at roll body 1 two ends, along with the rotation of roll shaft 5, cooling water is flowed fast by spiral stream guidance groove 2, improve cooling effectiveness and cold roll surface cool scope is large, cooling evenly, solve the cold roll temperature difference to cause contracting the inconsistent problem easy to crack that rises, extend the service life of cold roll, reduce maintenance frequency, lower production cost.The utility model is rational in infrastructure, easy to operate, failure rate is low, and the steel rolling performance using the utility model to produce is also better.
