Abstract
The utility model belongs to an improvement of the steel-rolling finishing mill roll-shifting connecting structure, in particular to an improved finishing mill roll-shifting connecting structure. A roll-shifting hydraulic cylinder piston rod is connected with a roll-shifting panel through a locknut and a round backing plate, the matched surfaces of the bore of the round backing plate and the roll-shifting hydraulic cylinder piston rod are provided with corresponding keyways, in which flat keys are mounted, screw holes with screw head countersinks, which are communicated with the roll-shifting panel, are circumferentially and evenly arranged on the outer end surface of the round backing plate, screw holes with screw head countersinks, which are communicated with the roll-shifting panel, are circumferentially and evenly arranged on the outer end surface of the locknut, the round backing plate and the roll-shifting panel are fixed together by hexagon socket screws, and the locknut and the roll-shifting panel are fixed together by hexagon socket screws. The connecting structure is reasonable, connection is firm and reliable, the radial rotation of the roll-shifting hydraulic cylinder piston rod can be effectively prevented, roll-shifting displacement is prevented, the roll-shifting accuracy is increased, the connecting structure can provide powerful support for the replacement of the rolls of a rolling mill, and is easy to maintain, and the expense for spare parts is reduced.
Description
Technical field
The utility model belongs to the improvement of steel rolling finishing mill roll shifting syndeton, particularly a kind of improved finishing mill roll shifting syndeton.
Background technology
Finishing mill working roll system is installed in the mill housing middle inside, moves axially working roll, and cooperation roller system finishes the positive roller to working roll, the plate shape of control band steel.Roll shifting is moved seat and is connected as a single entity by locking hydraulic cylinder and working roll bearing block, and simultaneously, roll shifting is moved seat and moved (panel links to each other with mill housing, maintains static) with the roll shifting panel by the roll shifting hydraulic cylinder.
Adopt thread connection between roll shifting hydraulic cylinder piston rod and the locking nut, locking nut is to be fixed on the roll shifting panel.Adjusting the roll shifting zero-bit after use a period of time, the positive positioning of roll shifting zero-bit can appear.Caused by following reason through actual analysis: 1, the alignment pin of locking nut is cut off or is out of shape, and causes the roll shifting positioning; When 2, the alignment pin of locking nut does not damage, in observing at the scene, find that the thread connection between roll shifting hydraulic cylinder piston rod and the locking nut is loosening, judgement is that the roll shifting hydraulic cylinder piston rod in use slowly radially rotates and causes.
Summary of the invention
The purpose of this utility model is to provide a kind of improved finishing mill roll shifting syndeton, it is rational in infrastructure, be connected firmly, reliably, can effectively prevent the radially rotation of roll shifting hydraulic cylinder piston rod, prevent the roll shifting positioning, improve the accuracy of roll shifting, provide strong support mill roll, safeguard and simply reduce the expense of spare part.
The purpose of this utility model is achieved in that a kind of improved finishing mill roll shifting syndeton, comprise that the roll shifting hydraulic cylinder piston rod is connected with the roll shifting panel with the planchet plate by locking nut, on the mating surface between planchet plate endoporus and the roll shifting hydraulic cylinder piston rod, corresponding keyway is being set, flat key is installed in keyway, on the outer face of planchet plate, be uniformly distributed along the circumference be provided with and communicate with the roll shifting panel, and screw with bolt head counterbore, on the outer face of locking nut, be uniformly distributed along the circumference be provided with and communicate with the roll shifting panel, and the screw with bolt head counterbore is between planchet plate and the roll shifting panel, fix by hexagon socket head cap screw respectively between locking nut and the roll shifting panel.
Be designed to key connecting between the planchet plate endoporus of the utility model roll shifting panel dorsal part and the roll shifting hydraulic cylinder piston rod; Fix with hexagon socket head cap screw between planchet plate and the roll shifting panel, the method for associative key connection and bolting has prevented the radially rotation of roll shifting hydraulic cylinder piston rod; Also adopt hexagon socket head cap screw to fix between locking nut and the roll shifting panel, prevented the radially rotation of locking nut.Through improved on-the-spot the use, stopped 1-2 times roll shifting positioning accident weekly; Eliminated hidden danger, improved the accuracy of roll shifting, provide strong support mill roll; Safeguard simply, reliable, all need finishing mill roll shifting to check every day before transforming.Only need in every month service work, carry out conventional maintenance after the transformation, reduce the spare part expense simultaneously.The utility model is rational in infrastructure, is connected firmly, reliably, has prevented the radially rotation of roll shifting hydraulic cylinder piston rod effectively, prevented the roll shifting positioning, improved the accuracy of roll shifting, provide strong support mill roll, safeguard simply, reduced the expense of spare part.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing, and accompanying drawing is a sectional structure schematic diagram of the present utility model.
The specific embodiment
A kind of improved finishing mill roll shifting syndeton, as shown in drawings, comprise that roll shifting hydraulic cylinder piston rod 1 is connected with roll shifting panel 3 with planchet plate 2 by locking nut 4, on the mating surface between planchet plate 2 endoporus and the roll shifting hydraulic cylinder piston rod 1, corresponding keyway is being set, flat key 6 is installed in keyway, on the outer face of planchet plate 2, be uniformly distributed along the circumference be provided with and communicate with roll shifting panel 3, and screw with bolt head counterbore, on the outer face of locking nut 4, be uniformly distributed along the circumference be provided with and communicate with roll shifting panel 3, and the screw with bolt head counterbore is between planchet plate 2 and the roll shifting panel 3, fixing by hexagon socket head cap screw 5 respectively between locking nut 4 and the roll shifting panel 3.Two symmetrical keyways are being set on the mating surface between planchet plate 2 endoporus and the roll shifting hydraulic cylinder piston rod 1.
Claims (2)
1. improved finishing mill roll shifting syndeton, comprise that roll shifting hydraulic cylinder piston rod (1) is connected with roll shifting panel (3) with planchet plate (2) by locking nut (4), it is characterized in that: on the mating surface between planchet plate (2) endoporus and the roll shifting hydraulic cylinder piston rod (1), corresponding keyway is being set, flat key (6) is installed in keyway, on the outer face of planchet plate (2), be uniformly distributed along the circumference be provided with and communicate with roll shifting panel (3), and screw with bolt head counterbore, on the outer face of locking nut (4), be uniformly distributed along the circumference be provided with and communicate with roll shifting panel (3), and the screw with bolt head counterbore is between planchet plate (2) and the roll shifting panel (3), fixing by soket head cap screw (5) respectively between locking nut (4) and the roll shifting panel (3).
