Abstract
The utility model relates to a side-pressing roller system supporting structure of a belt material eighteen-high cold-rolling mill, comprising a hanging rack arranged on an intermediate roller bearing seat; the bottom end part of the rack is fixedly connected with a large bracket and a small bracket by mounting screws; a core shaft is arranged on the hanging rack; the hanging rack is further provided with an intermediate roller, a working roller, a side pressing roller, a large core roller and a small core roller; the hanging rack outside of the large core roller is provided with a large back lining bearing roller, and the hanging rack at the outside of the small core roller is provided with a small back lining bearing roller; and the core shaft is a straight core shaft and is externally provided with an adjusting sleeve which is fixed on the hanging rack by a fastening screw. The outer wall of the adjusting sleeve is circumferentially provided with a ring-shaped groove. The pressing roller system supporting structure of the belt material eighteen-high cold-rolling mill has the benefits of reasonable roller system and roller diameter configuration, avoiding the eccentric type structure of the core shaft, completely adopting the form of the straight core shaft, further reducing the lifting adjustment operation of the side pressing roller system, and greatly facilitating the operation, the maintenance and use of equipment.
Description
Technical field
The utility model relates to band 18 cold mill side pressing roll systems supporting structures.
Background technology
Along with the development of industrial technology, people more and more need material various, and thickness is thinner, the better sheet metal strip of template.For rolling such band, people have to research and develop small diameter roller (drafts when increasing strip-rolling also reduces the elastic flattening value of roll) milling train.And roller diameter reduces to cause roll rigidity not enough.In order to solve this contradiction, people have researched and developed both has little roller diameter, has new structure milling train---the 18 roller finishing rolling mills of the tower backing roll system of good stiffness again.
Ten mkw mill rollers system arranges and adopts tower rollers system, and employed work roll diameter is all less; Tower rollers fasten down be arranged in symmetrically two closed type door type memorial archways (traditional type four, six-high cluster mill memorial archway style, help four, the transformation of six-high cluster mill low-cost and high-precision) in.This roller is that arrangement space is arranged all very compactness, and a large amount of position observation test difficulties cause Installation and Debugging, maintaining to waste time and energy.At present, widely used ten mkw mill side pressing roll systems supporting constructions are supporters---mandrel centering type structure.Because the continuous variation in milling train intermediate calender rolls, help roll, backing cloth bearing roller and working roll roller footpath causes side pressing roll systems side pressure ability constantly to change and do not have rational method of testing and criterion, often cause that operating efficiency is low, band shape is unusual even milling train scratches the strip surface situation and occurs.Therefore need design high accuracy band 18 cold mill side pressing roll systems supporting constructions a kind of rational in infrastructure, easy to use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of unusual even milling train scuffing strip surface situation appearance of shape of not only can effectively avoiding causing being with is provided, and can effectively reduce Installation and Debugging, maintaining degree, significantly improve the band 18 cold mill side pressing roll systems supporting structures of milling train utilization rate.
The technical scheme that provides according to the utility model, described band 18 cold mill side pressing roll systems supporting structures, be included in the hanger of installing on the intermediate calender rolls bearing block, the hanger bottom is by fixedly connected big support and the small rack of mounting screw, mandrel is installed on hanger, intermediate calender rolls, working roll, side pressure roller, big core roller and little core roller also are installed on hanger, be provided with big backing cloth bearing roller on the hanger outside big core roller, the outer hanger of little core roller is provided with little backing cloth bearing roller, and described mandrel is straight axle.
Be provided with regulating sleeve outside mandrel, regulating sleeve is fixed on the hanger by trip bolt.The outer wall of described regulating sleeve circumferentially offers annular recess.
The beneficial effects of the utility model are: reasonably roller is that roller directly disposes, and avoids mandrel centering type structure, adopts straight mandrel form fully, has reduced the lift adjustment work of side pressing roll systems, greatly facilitates the equipment operation, safeguards and use.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the mandrel structural representation in the utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly by mandrel 1, intermediate calender rolls bearing block 2, hanger 3, big support 4, screw 5, be rolled band steel 6, big backing cloth bearing roller 7, big mandrel 8, small core shaft 9, little backing cloth bearing roller 10, small rack 11, side pressure roller 12, working roll 13, intermediate calender rolls 14, regulating sleeve 15, trip bolt 16, constitute with annular recess 17 etc.
These band 18 cold mill side pressing roll systems supporting structures, be included in the hanger of installing on the intermediate calender rolls bearing block 23, hanger 3 bottoms are by mounting screw 5 fixedly connected big support 4 and small rack 11, mandrel 1 is installed on hanger 3, intermediate calender rolls 14, working roll 13, side pressure roller 12, big core roller 8 and little core roller 9 also are installed on hanger 3, be provided with big backing cloth bearing roller 7 on the hanger 3 outside big core roller 8, little core roller 9 outer hangers 3 are provided with little backing cloth bearing roller 10, and described mandrel 1 is straight axle.
Be provided with regulating sleeve 15 outside mandrel 1, regulating sleeve 15 is fixed on the hanger 3 by trip bolt 16.The outer wall of described regulating sleeve 15 circumferentially offers annular recess 17.
During work, along with the wearing and tearing and the grinding of roll (backing roll, intermediate calender rolls 14, side pressure roller 12, big backing cloth bearing roller 7, little backing cloth bearing roller 10) are changed, the external diameter of each roll constantly changes in the milling train, thereby the facade position of each roller shown in Fig. 1 is also along with variation, and big backing cloth bearing roller 7 when serious, 12 position meeting of side pressure roller (along with roller diminishing directly) drop to rolling can't carrying out.In order to keep the correct stressed position of each roll of milling train, avoid occurring big backing cloth bearing roller 7, side pressure roller 12 positions are crossed low and influence of rolled (stressed and technological lubrication situation, be rolled band steel plate 6 surface damages etc.), in the ten traditional mkw mill side pressing roll systems supporting structures, centering type is processed in 1 design of supporter---mandrel, big backing cloth bearing roller 7 appears when it is believed that, side pressure roller 12 positions are crossed low and during influence of rolled, usually adopt the eccentric mandrel of artificial rocking-turn to improve the side pressing roll systems position by force and handle.Because the operating space is narrow and small and lack rational detection mode and criterion, this manual work mode waste time and energy often and also end product undesirable.
When intermediate calender rolls 14 external diameter scopes are Φ 215～Φ 230, big backing cloth bearing roller 7 external diameter scopes are that Φ 83～Φ 85, little backing cloth bearing roller 10 external diameters are Φ 58～Φ 60, side pressure roller 12 external diameter scopes are Φ 80～Φ 90, when working roll 13 external diameter scopes are Φ 90～Φ 100, supporter---mandrel 1 preferably makes straight heart-shaped formula but not eccentric shaft, the correct stressed position that can guarantee simultaneously.
