Abstract
The utility model provides a positive roller bending device of finishing mill in hot continuous rolling line, which consists of four parts comprising a changing rolling side input end, a changing rolling side output end, a transmission side output end and a transmission side input end. The four parts are respectively connected with each other by a bolt, a slopping key and a protruding stage, a clamp opening at the seat body and four upright posts of the frame. The four mechanisms are provided with two hydraulic oil tanks which are arranged up and down to face to each other, the rod heads of the all hydraulic oil tanks are provide with an automatic core adjusting mechanism. The utility model has the advantages that: the power of the rolling-bending is large and adjustable, the hydraulic tank has the radial direction prevention impact force, and the device is fixedly connected with the frame upright post. The utility model will not loose under a thousands tons rolling force, the structure is tight, the volume is small, and the intensity is high etc.
Description
The utility model relates to the improvement of the positive roll-bending device of a kind of continuous hot-rolling mill, is particularly suitable for the transformation of existing continuous hot-rolling mill is used.
According to the knowledge of the applicant: positive roll-bending device is the important device of hot steel strip continuous rolling line mm finishing mill unit, it is assemblied in the finishing mill central rack, be used to compress working roll and backing roll and carry out steel rolling, or be used for working roll is implemented positive curve, change work roll crown, make by the rolled steel plate template to reach high-precision requirement.Adopt on the present domestic finishing mill by the positive roll-bending device that abroad manufactures and designs, its shortcoming is that the hydraulic cylinder rod head is the rigid rod head, directly applies pressure to working roll bearing block and reach and compress or the purpose of roller, this rigid rod head can not self-alignment, anti-impact force is poor, hydraulic cylinder is fragile, maintenance is frequent, causes production efficiency low.In addition, the positive roll-bending device of this class and framework memorial archway be connected be easy to become flexible the excessive milling train intensity that influences of fluting on frame that has.
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art part, designs and manufactures the positive roll-bending device of hot-rolling line finishing mill that can effectively overcome the said apparatus shortcoming.
The purpose of this utility model is such realization: comprise by the changing side input, the changing side output, the transmission side input, transmission side output four parts are formed, this four part closely links to each other with four columns of frame by boss, jaw on bolt, taper key and the pedestal respectively, be equipped with upper and lower opposed two hydraulic cylinders on four devices, all be provided with automatic aligning mechanism at the bar head of hydraulic cylinder.
Described automatic aligning mechanism is connected and composed with bolt by head guide rod spherical in shape, dimple, sealing, gland.
Because adopting said structure to make the utlity model has: bending roller force is big, bending roller force is adjustable, the hydraulic cylinder rod head has anti-radial impact power, device is connected firmly with framework pillar, the column fluting is little, column intensity weakens little, not loosening under the thousands of tons of roll-force, apparatus structure compactness, little, the intensity advantages of higher of volume.The special adaptation, increase this equipment newly when continuous hot-rolling mill is transformed.
Further describe below in conjunction with accompanying drawing:
Fig. 1 is a finishing mill front view of the present utility model.
Fig. 2 is the enlarged drawing of the positive roll-bending device among Fig. 1.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the local figure of the retaining mechanism among Fig. 2.
With reference to Fig. 1--Fig. 4, positive roll-bending device is by changing side input 1, changing side output 2, transmission side output 3 and transmission side input 4, four parts are formed.Changing side input 1 and changing side output 2 are symmetric arrangement, and structure is identical.Transmission side output 3 and transmission side input 4 also are symmetric arrangement, and structure is identical.The changing side input by pedestal 5, go up latch 6, down latch 7, go up hydraulic cylinder 8, hydraulic cylinder 9, wearing plate 10, long taper key 11, weak point taper key 12 are formed down.The transmission side input is made up of pedestal, last hydraulic cylinder, following hydraulic cylinder, wearing plate, long and short taper key.Above-mentioned four part bodies closely link to each other with four columns of frame by boss, jaw on bolt 13, taper key (11,12) and the pedestal 5 respectively.Be bolt closing, by the bolt 13 of 10 band pretightning forces pedestal 5 tightly on frame; Boss, jaw are inlayed, and the boss at pedestal 5 middle parts, jaw are simultaneously at the framework pillar of four directions embedding up and down; Packing in taper key wedge jail, pedestal 5, two sides adopt long taper key 11 in front and back behind the framework pillar, and junction pretension bolt 13 is strained taper keies between short taper key 12 wedgings and framework pillar, and framework pillar and pedestal 5 are connected as a single entity, zero-clearance is seamless thereby make.This structure makes that this device can bear radially, axial enormous impact power in the rolled plate process.Be equipped with opposed two hydraulic cylinders (8 and 9) up and down in described four mechanisms (1,2,3,4).The utility model bar head of eight hydraulic cylinders altogether all is provided with automatic aligning mechanism, so that the bar head can locate automatically, still can realize positive roller when steel rolling situation bottom working roll is subjected to axial impact force, to change the work convexity, to improve plate shape precision.Automatic aligning mechanism is connected and composed by head guide rod 14 spherical in shape, dimple 15, sealing 16, gland 17 usefulness bolts.When the huge axial force of rolling generation, guide rod 14 can produce certain deviation with axial force, avoided the rigid rod head to fracture and cylinder in the shortcoming of bad seals.The frictional force that wearing plate 10 adopts special substances, puts together on the pedestal 5, bears working roll bearing block, last latch 6 and following latch 7 put together on the pedestal 5, its effect be when rolling the axial locking working roll, prevent that the working roll string from moving.
This program of installing crooked working roll is: before milling train was nipped steel plate rolling, the pressure of last hydraulic cylinder 8, following hydraulic cylinder 9 was given according to operator or higher level's computer control by PLC.Promptly this moment, pressure big I was by manually providing, also can be provided by the computer that specific software is housed of forming the closed loop feeder with instrument such as profile gauge, planimeters according to the steel plate deformed situation.This pressure makes up and down, and hydraulic cylinder (8,9) head stretches out, presses respectively working roll bearing block and bottom working roll bearing block separately.When pressure given hour, its effect is to compress working roll and backing roll to prevent that both from skidding so that steel rolling.When pressure given increases, then reach crooked working roll and change its convexity raising by the purpose of rolled steel plate plate shape precision.
After stopping the release of rolling mill compound cylinder pressure, this device cooperates other mechanism can realize work roll changing.
