Description

Using electronically controlled composite (back-up) roll

Technical field

The utility model is related to machine tools, and in particular to using electronically controlled composite (back-up) roll.

Background technology

Roll is the instrument for making metal produce plastic deformation, is the important consumption portion for determining rolling mill efficiency and mill bar quality Part.Roll is the strength member on rolling mill, and using the pressure produced when a pair or one group of roll rolling stone roller steel are rolled.It leads Bear Dynamic And Static Loads during rolling, abrasion and the impact of temperature change.Roll has different sorting techniques.Press body of roll shape point For cylinder and non-cylindrical, the former is mainly used in sheet material, band, section bar and wire production, and the latter is mainly used in tubing production. It is divided into work roll and backing roll by whether rolled piece is contacted.The roll of directly contact rolled piece claims work roll；Roll to increase work The rigidity and intensity of roller and be placed in the work roll back side or side is not directly contacted with the roll of rolled piece and claims backing roll.By using machine Frame is divided into bloom roll, shaping roll, central roll and planishing roll.It is divided into strip roll, beam-and-rail roll, wire rod by the kind of stocking to roll Roller and tubing roll etc..Also hot roll and cold roll can be divided into by the state of rolled piece during rolling.Roll species is a lot, and conventional rolls Roller kind has cast steel roll, grain roll and forging roller three major types, also has a small amount of hard alloy roll on bar and shape mill.Roll The condition of work of roll is the most complicated in machine part.Roll manufacture and using front preparatory process in can produce residual stress and Thermal stress.The effect of various cyclic stresses is further received when using, include bending, torsion, shearing, contact stress and Thermal stress etc..These stress along the body of roll it is being unevenly distributed, be continually changing, its reason does not only have design factor, also Roll weares and teares in use, temperature and roller shape are continually changing.Additionally, often there are abnormal conditions in rolling condition.Roll exists Improper, the infringement that also can be thermally stressed using rear cooling.So roll is in addition to abrasion, often there is crackle, fracture, stripping in also Jing Fall, various local damages and the surface damage such as impression.Generally surface produces the roll for damaging and is then no longer appropriate for carrying out roll work, Needs are changed on whole roll, but this replacing greatly slatterns the roll shoulder that can also normally use.

Utility model content

Technical problem to be solved in the utility model is that the roll that usual surface generation is damaged then is no longer appropriate for being rolled Roller works, and needs are changed on whole roll, but this replacing greatly slatterns the roll shoulder that can also normally use.Cause This purpose of this utility model is to provide using electronically controlled composite (back-up) roll, when the traditional roll of solution is not suitable for work High cost problem with regard to replacing whole roll.

The utility model is achieved through the following technical solutions：

Using electronically controlled composite (back-up) roll, including jointing, roll body and roll shoulder；The roll body is circle Column type, is provided with a criss-cross gear block at the axis of two end face, be also provided with to hold on two end faces Equally distributed eight screwed holes II of line centered on the axis of face.A jointing is provided with the two ends of the roll body, The jointing it is cylindrically shaped, be provided with equally distributed eight spiral shells of the line centered on the axis of jointing Pit I, the screwed hole I runs through jointing.A resigning is provided with the axis of an end face of the jointing The groove of the cross gear block arranged on roll body, the groove is cross；In another end face of the jointing Axis at be provided with the roll shoulder of a column type.The jointing is coordinated with gear block by groove with roll body and is connected Connect, also by bolt successively with jointing on arrange screwed hole I and roll body on arrange screwed hole II be connected. The material of the roll body is tungsten steel alloy, and this hard alloy of wolfram steel has high, wear-resisting hardness, intensity and toughness preferable, resistance to A series of premium properties such as hot, corrosion-resistant, particularly its high rigidity and wearability, even if also basic at a temperature of 500 DEG C Keep constant, still have very high hardness at 1000 DEG C.

Further, the groove makes roll shoulder pass while obtaining power with gear block with interference fit is combined into Roll body is passed, the synchronism of roll body and roll shoulder is improved, its joint face and the bolt on joint face is protected.

Further, the outer surface of the roll body is provided with one layer of chrome plating.After electroplated chromium is processed, roll is known from experience to be had Surfacing, it is bright and clean, be easy to the demoulding, the advantages of will not getting rusty.

The utility model is arranged on milling train.Rolling mill main will by roll, mill housing, bearing bag, bearing, workbench, roll Steel guide and guard, rail chair, roll adjusting device, top-roll-balance arrangement, control device, driving means and changing rig etc. are constituted, its Motor in middle driving means provides power to roll, makes roll normal work；Meanwhile, the Electronic Control constraint in control device Mechanical course, so as to control the working condition of roll, so that roll adapts to different materials to be processed.

The utility model compared with prior art, has the following advantages and advantages：

1st, the utility model adopts electronically controlled composite (back-up) roll, roll shoulder and roll body to separate, and is easy to roll body When being no longer appropriate for work, only roll body need to be changed, changing new roll body just can be with, and roll shoulder is continuing with, Reduce cost；

2nd, the utility model adopts the connection of electronically controlled composite (back-up) roll, roll shoulder and roll body not only to pass through spiral shell Bolt is attached with the cooperation of screwed hole, also by the criss-cross gear on the criss-cross groove on roll shoulder and roll body Position block interference fit connection, further strengthens synchronization during compactness and the work of the connection of roll shoulder and roll body Property, preferably protect the bolt that roll shoulder and roll body are connected；

3rd, the utility model adopts electronically controlled composite (back-up) roll, roll body to adopt this alloy of wolfram steel, enhance and roll The hardness and wearability of roll body, and the surface of roll body is provided with nickel coating or chrome plating or molybdenum coating, increase further strong The wearability of roll.
