Description
Technical field
The utility model relates to a kind of for controlling the backing roll of thin copper belt material template quality.
Background technology
Along with scientific and technical development, client is more and more higher to the quality requirement of high accuracy copper and alloy strip steel rolled stock thereof.Wherein, as high-precision copper strap material, except requiring strictly to product chemical composition, dimensional accuracy, surface quality, also very strict to the requirement of template quality, due to compared with the distinctive feature of thin copper belt, always poor at cold rolling rear template, there is both sides wave phenomenon.The generation of flatness defect is because rolled piece is in the operation of rolling, wide to inequality extending longitudinally in direction and the result occurring.During distortion, extending large part therefore can produce additional compression, extends little part and can produce additional potential stress.When this additional compression surpasses certain critical value, there will be the phenomenon that is similar to compression rod unstability, show this part strip and produce multi-form bending, form the defects such as wave, wooden dipper song.Along wide to difference extending longitudinally larger, the additional stress in rolled piece is higher, flatness defect is just more serious.
Template refers to the glacing flatness of strip, and whether strip produces waveform, warpage, lateral bending, wooden dipper song etc.The original blank of a good plate cut, in process, the quality of its template, depend on strip along wide in direction extension whether equate.When strip both sides, extend to be greater than when extend at middle part and produce symmetrical bilateral wave, otherwise produce middle wave, when depress when inconsistent on both sides, drafts large (extending also large) one side produce single wave or lateral bending.Longitudinal at rolled piece when wave, while laterally increasing, can produce wooden dipper song simultaneously.Be decided by the operation of rolling along wide whether uniformity extending longitudinally in direction simultaneously, and the shape of roll gap is to affect the whether even main factor of Strip distortion, take four-high mill as example, as shown in Figure 1: in rolling during than the band of the narrow certain width of work roll surface, contact portion between working roll and backing roll forms a harmful moment of flexure outside bandwidth, make working roller bending, finally have influence on plate shape.Harmful moment of flexure has been offset the effect of very most of bending roller force in addition, and result has also hindered the performance of hydraulic bending roll effect.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of for controlling the backing roll of thin copper belt material template quality.
The utility model solves the technical scheme that its technical problem adopts: a kind of for controlling the backing roll of thin copper belt material template quality, comprise roll body, roll body comprises plain-barreled roll and the symmetrical tapered roller that is connected in plain-barreled roll two ends that is positioned at middle part, the maximum gauge of tapered roller and the equal diameters of plain-barreled roll, plain-barreled roll and tapered roller connect as one structure, and the junction of plain-barreled roll and tapered roller seamlessly transits; The tapering of tapered roller is 0.0014～0.0018, and the Length Ratio of plain-barreled roll and tapered roller is (330～350): (40～50).
The beneficial effects of the utility model are: the inhomogeneous extension of rolling strip limit portion is well ensured, band can meet in the middle of customer need actual production, by the widest product in dissimilar, formulate the size of grinding backing roll, when the band of rolling respective width type, the territory, harmful contact area of backing roll and working roll can reduce greatly like this; For narrower band in same width type, by adjusting little bending roller force, just can change the shape of roll gap, reach the object of control panel shape.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the fundamental diagram of four-high mill;
Fig. 2 is structural representation of the present utility model.
Wherein: 1. plain-barreled roll, 2. tapered roller.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 2 a kind of for controlling the backing roll of thin copper belt material template quality, comprise roll body, roll body comprises plain-barreled roll 1 and the symmetrical tapered roller 2 that is connected in plain-barreled roll 1 two ends that is positioned at middle part, the equal diameters of the maximum gauge of tapered roller 2 and plain-barreled roll 1, plain-barreled roll 1 connects as one structure with tapered roller 2, and plain-barreled roll 1 seamlessly transits with the junction of tapered roller 2; The tapering of tapered roller 2 is 0.0014～0.0018, and plain-barreled roll 1 is (330～350) with the Length Ratio of tapered roller 2: (40～50).
In order to eliminate or reduce the impact of harmful moment of flexure, can, for the width of rolled material, harmful contact site, the both sides of corresponding backing roll be ground to double tapered.For four-high mill, we are the backing roll of Φ 550 * 430 life size, are ground to the roll surface width 330mm of middle part plain-barreled roll 1, the tapered roller 2 of each 50mm width of two, and tapered roller 2 minimum diameters are than the little 0.07～0.09mm of the diameter of plain-barreled roll 1.Working roll is disengaged in region outside bandwidth contacts with backing roll.Adopt this kind of method, the lateral stiffness of milling train is large, the impact that working roll amount of deflection is not changed by roll-force, plate shape good stability.
By after the tapering grinding of backing roll limit portion, Strip Shape quality is greatly improved, especially the little limit wave of strip, has obtained eliminating thoroughly.If former radio-frequency cable band trimmed size is 0.2 * 41, not before implementing measure, in the operation of slitting; often can cause because plate shape is poor uneven the scrapping of material volume, after some itemize, because of lateral bending, the excessive client of causing cannot use; after measure is implemented, above-mentioned phenomenon is thoroughly eliminated.
Product to different in width, can determine the roll shape size of one-level backing roll the large part of output by width.By changing roll shape, the harmful contact area of working roll and backing roll beyond minimizing made-up belt width that even elimination is rolled, can realize the good control to plate shape completely as far as possible.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
