Abstract
The invention discloses a replacement device for a backup roller and an intermediate roller of a rolling mill. The replacement device comprises strip-shaped sliding rails, wherein two slidable bearing pedestal fixing platforms are arranged on the sliding rails; two push rod oil cylinders for moving the bearing pedestal fixing platforms are separately arranged at the two ends of the sliding rails; two carrier rollers arranged along the parallel direction of the sliding rails are arranged between the two bearing pedestal fixing platforms; and carrier roller brackets and oil cylinders for lifting the carrier rollers are arranged under the two carrier rollers. With the adoption of the replacement device, the replacement efficiency and replacement precision of the backup roller and the intermediate roller of the rolling mill can be improved; roller barrel abrasion and deformation which are caused in disassembling and assembling processes can be avoided; and the replacement device has the advantages of simplicity in operation, convenience in control, wide in application range, and the like.
Description
Technical field
The invention belongs to field of metallurgical equipment, being specifically related to a kind of device for changing roller mill backing roll and intermediate calender rolls.
Background technology
In roller mill production process, need old roller mill backing roll or intermediate calender rolls to dismantle from roller mill bearing block to change, because the bearing block spacing at backing roll and intermediate calender rolls two ends is inconsistent, bearing block appearance difference is large, cause disassembling, mounting process is complicated, inefficiency, and required device volume is large, kind is many.Disassemble in process, if roller mill backing roll and intermediate calender rolls and two bearing block discontinuity, backing roll and intermediate calender rolls wearing and tearing, distortion can be caused toward contact, thus the roller mill quality of production is declined.Still be not exclusively used in the whole set replacement device of roller mill backing roll and intermediate calender rolls at present.
Summary of the invention
The object of the invention is for above-mentioned defect, provide that a kind of this device has easy and simple to handle for roller mill backing roll and intermediate calender rolls are dismantled from roller mill bearing block the device carrying out changing, disassemble that efficiency is high, precision advantages of higher.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of roller mill backing roll and intermediate calender rolls more changing device, comprise a strip slide rail, described slide rail is provided with two bearing block fixed stations that can slide, the two ends of described slide rail are respectively equipped with a push rod oil cylinder for moving shaft holder fixed station, be provided with two carrying rollers along the arrangement of slide rail parallel direction between described two bearing block fixed stations, described two carrying rollers have carrier roller frame and the oil cylinder for moving vertically idler frame.
Described two bearing block fixed stations are equipped with for by bearing block fixed station along perpendicular to the screw rod of slide rail direction movement.
Described carrying roller is provided with the motor for rotating idler, and described motor is located on one of them carrying roller.
Described two bearing block fixed stations are equipped with the T-shaped draw-in groove for fixed bearing block.
Described slide rail is two-part structure, and described two bearing block fixed stations lay respectively on two sections of slide rails.
In the present invention, two carrying rollers are used for lifting and positioning supports roller and intermediate calender rolls, guarantee that the bearing block at two ends and the center of gravity of backing roll or intermediate calender rolls are on same level line, when two bearing block fixed stations move to slide rail two ends simultaneously, being separated and disassembling of backing roll and intermediate calender rolls and bearing block can be realized.Two bearing block fixed stations all can move along the direction perpendicular to slide rail, and object is the bearing block adapting to difformity, size, guarantees the bearing block uniform force at the body of roll and two ends further, prevent wearing and tearing and distortion.Motor on carrying roller rotates for driving carrying roller, when one of them carrying roller rotates, lifted backing roll or intermediate calender rolls can be driven to rotate, thus the position of the adjustment body of roll and direction, guarantee that the center of gravity of the body of roll and bearing block is positioned on same level straight line further.T-shaped draw-in groove on bearing block fixed station is used for fixed bearing block, prevent it from moving on fixed station, the slide rail of two-part structure is convenient to volume and the floor space of reduction equipment, simultaneously also in order to improve the precision disassembled, install of various profiled roller and bearing block thereof further.
The present invention can improve replacing efficiency and the precision of roller mill backing roll and intermediate calender rolls to greatest extent, and the body of roll wearing and tearing prevent from disassembling, causing in installation process and distortion, have simple to operate, control the advantages such as convenient, applied widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-slide rail, 2-bearing block fixed station, 3-push rod oil cylinder, 4-carrying roller, 5-carrier roller frame, 6-oil cylinder, 7-screw rod, 8-motor, 9-T shape draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in detail.
Embodiment: as shown in the figure, a kind of roller mill backing roll and intermediate calender rolls more changing device, comprise a strip slide rail 1, described slide rail 1 is provided with two bearing block fixed stations 2 that can slide, the two ends of described slide rail 1 are respectively equipped with a push rod oil cylinder 3 for moving shaft holder fixed station 2, two carrying rollers 4 along the arrangement of slide rail 1 parallel direction are provided with between described two bearing block fixed stations 2, described two carrying rollers 4 have carrier roller frame 5 and the oil cylinder 6 for moving vertically idler frame 5, described two bearing block fixed stations 2 are equipped with for by bearing block fixed station 2 along the screw rod 7 perpendicular to slide rail 1 direction movement, described carrying roller 4 is provided with the motor 8 for rotating idler 4, described motor 8 is located on one of them carrying roller 4, described two bearing block fixed stations 2 are equipped with the T-shaped draw-in groove 9 for fixed bearing block, described slide rail 1 is two-part structure, described two bearing block fixed stations 2 lay respectively on two sections of slide rails 1.
In roller mill production process, old backing roll or intermediate calender rolls need to dismantle from roller mill bearing block to change, first two carrying rollers 4 are placed in the below at backing roll or intermediate calender rolls, then start oil cylinder 6 lifts on device of the present invention by backing roll or intermediate calender rolls together with bearing block, and bearing block is separately fixed on two bearing block fixed stations 2, by adjusting position and the rotating idler 4 of bearing block fixed station 2 and carrying roller 4, the center of gravity of the body of roll and two bearing blocks is made to be positioned on same level straight line, for profiled roller or the widely different bearing block of shape size, can also be adjusted by the position of adjustment two sections of slide rails 1.Finally restarting push rod oil cylinder 3 makes bearing block fixed station 2 move to two ends, thus the body of roll is separated with the bearing block at two ends.
When installing new backing roll or intermediate calender rolls on roller mill, can operate according to principle identical above.This device precision is high, can not cause wearing and tearing and the distortion of the body of roll, significantly can also increase work efficiency simultaneously, reduce labour cost disassembling, in installation process.
