The base is foxed to the ground through a bolt; the hydraulic cylinder is installed on the base; the movable connection roller frame and the adjustment screw are installed on two sides of the hydraulic cylinder respectively; the movable roller seat is installed on the movable roller frame through the baffle; the fixed roller frame is fixed to the base through a bolt; the fixed roller seat is installed on the fixed roller frame through the baffle; the dust cover covers the hydraulic cylinder. The strip steel coiling assisting hanging-type five-roller tensioning device has the advantages of being capable of being fully suitable for the high-temperature protection environment, having much iron oxide dust, in a steel mill and convenient to assemble, disassemble and lubricate, effectively controlling strip steel coiling speed and tightness, effectively improving rolling speed, and reducing production and maintenance costs.
Description
Technical field
The utility model belongs to clot swelling device technical field, particularly provides a kind of for being with the steel clot to assist suspension type five roller swelling devices, is adapted to the auxiliary swelling device of steel rolling mill's band steel clot.
Background technology
At present, the structure of the general five roller swelling devices that adopt of strip mill is comprised of three roller framves, two roller framves.The roller frame is comprised of the connected bearing block of two rows, self-aligning roller bearing, thrust ball bearing and roller.The drawback of this structure is as follows:
1, very easily pile up as shown in hydrous ferric oxide (as Fig. 1) because the two rows bearing block is connected in connecting portion mutually, thereby pave roller, cause that roller is stuck not to be turned;
2, in the roller high-speed cruising due to the sprinkling of cooling water and the generation of iron scale, the bearing block that water and iron oxide very easily enter the below oil-containing forms iron greasy filth, the wool felt sealing can not effectively stop the people that advances of iron oxide and water, thereby steep bearing, causes the bearing locking;
3, the bearing block of below is not easy to online lubricating, and operating high-temperature steel belt distance axis bearing is nearer, and the lubricating oil in bearing block is easily flowed away with cooling water.Cause lubricated bearing locking not in time.
4,, because roller shell, axle 5 are integrative-structures, wherein the roll surface wearing of one side or bearing position wearing and tearing all will all be changed, and cause production cost to increase.Above problem causes, and in production work, more the roll change frame is frequent, affects or upsets rhythm of production.
Summary of the invention
It is a kind of for being with the steel clot to assist suspension type five roller swelling devices that the purpose of this utility model is to provide, and overcome the problem that iron oxide is easily piled up and advanced to existing five roller swelling device bearing blocks.This device has not only solved iron oxide and has piled up problem and avoided cooling water, iron oxide to enter in bearing block.And improved greatly the speed of changing five roller arrangements, use operation in being convenient to produce.Can fully be suitable for that steel rolling mill's iron oxide dust is many, the production environment of high temperature, be convenient to installing/dismounting and online lubricated, effectively control band steel clot speed and tightness.Make to produce rolling rhythm and effectively improve, reduced the production maintenance cost.
The utility model comprises: base 1, hydraulic cylinder 2, movable roller seat 3, movable roll frame 4, fixedly roller seat 5, stationary roll frame 6, axle 7, roller 8, adjusting screw(rod) 9, dust cover 10, baffle plate 11.
Operation and maintenance form of the present utility model is: the flexible drive movable roll seat by hydraulic cylinder travels forward.Lead and make the movable roll frame keep moving equilibrium with adjusting screw(rod) 9, by the nut at adjusting screw(rod) two, adjusting expanding force.In the working service process, only have the roller working face to be worn.So need to change roller seat, what adopt due to roller seat and roller frame (movable roll frame and stationary roll frame) is Baltimore groove and baffle plate 11 installation forms, only baffle plate need to be taken out and can hang out roller seat.
The time taper roll bearing 13 and the self-aligning roller bearing 14 that mainly are subject to that therefore radial load adopts due to the operation central roll.Roller 8 and axle 7 adopt Split type structure, and axle is fixed on top by bearing, is suspended structure.Roller is bumped into axle from below again, is bumped into position and adopts the 1:25 tapered configuration to prevent from becoming flexible.Roller is bumped into the back lower place on axle and fixes with nut 12.By adjusting nut, make roller firm.Due to, the below of tumbler does not have bearing block, has just avoided the accumulation of iron oxide and entering of cooling water.Roller and axle only need to be pulled down nut replacing roller after adopting its roll surface wearing of two body structures.
The beneficial effects of the utility model are that roller frame and roller seat adopt concaveconvex structure to facilitate dismounting and the roll change of rolling off the production line on line, the catastrophic failure of having avoided cooling water and iron oxide to cause damage to cause to bearing; Saved Bearing Consumption and alleviated manual maintenance pressure, changed when roller shell is convenient has greatly reduced production cost and guaranteed rhythm of production.

In figure, cooling water L, bearing block c, self-aligning roller bearing d, thrust ball bearing h and roller f, wool felt sealing e, base 1, hydraulic cylinder 2, movable roller seat 3, movable roll frame 4, fixedly roller seat 5, stationary roll frame 6, axle 7, roller 8, adjusting screw(rod) 9, dust cover 10, baffle plate 11, nut 12, taper roll bearing 13, self-aligning roller bearing 14, pump nozzle 15, five roller swelling device W. steel band G.
The specific embodiment
The utility model comprises: base 1, hydraulic cylinder 2, movable roller seat 3, movable roll frame 4, fixedly roller seat 5, stationary roll frame 6, axle 7, roller 8, adjusting screw(rod) 9, dust cover 10, baffle plate 11.
When steel band G enters five roller swelling device W, hydraulic cylinder 2 stretches out balance auxiliary pushing movable roll frame 4 at adjusting screw(rod) 9 and advances and rely on fixedly roller seat 5, with this, makes movable roller seat 3 and the fixing steel band G of roller seat 5 in the middle of clamping.Just formed the state shown in Fig. 2.The coiling machine in the place ahead pulls steel band, 8 rotations of steel strip driving roller.
What use due to roller assembling is suspended structure, washed away in the hole of iron oxide below falling under the washing away of cooling water.Iron oxide can not advance in people's bearing holder device.Thereby avoided the impact of iron oxide on bearing block.
In the equipment on-line use procedure, can by 15 pairs of bearings of pump nozzle 13,14, be lubricated at any time.So greatly increased equipment on-line service life.
When roller seat is changed, then the liner plate 11 of first dismantling is crossed the lifting screw with the steel wire rope string and is hung out roller seat is changed with crane.So just avoided due to the uneven damage to Baltimore groove of lifting.
