Abstract

The utility model discloses a strip steel auto-rectifying roller bed comprising a roller bed frame, a roller seat, and at least one roller unit. The roller seat is fixed on the roller bed frame. The roller units are symmetrically disposed on the roller seat along an operation center line of unit strip steel. Each roller unit comprises a roller shaft, a shaft sleeve, bearings and retainer rings; the bearings are mounted on the roller shaft; the shaft sleeve sleeves the roller shaft; the retainer rings are disposed between the outer ends of the bearings and the shaft sleeve; two ends of the roller shaft are mounted on the roller seat; the axis of the roller shaft and the operation center line of the unit strip steel form an included angle of 75-90 degrees. The strip steel auto-rectifying roller bed has the advantages that chances of the strip steel to deviate during the conveying process are reduced effectively, free swinging of the strip steel is avoided and normal operation of rotary shears is ensured.

Description

Band steel automatic deviation correction roller-way
Technical field
The utility model belongs to steel rolling production-line equipment technical field, is specifically related to a kind of band steel automatic deviation correction roller-way.
Background technology
Strip running deviation is the ubiquitous production difficult problem of steel rolling production-line, and it not only affects stable operation of unit, causes steel edge portion damage, reduces product lumber recovery, occurs broken belt, damage equipment even when serious.In push pull pickling line production process, due to the particularity of its production technology, band steel relies on pinch roll to promote and coiling machine pulls a volume one volume intermitten service, therefore be with steel in the time of threading and whipping, all the time in without tension force running status, sideslip very easily while operation on rollgang, is easy to depart from unit centre line and impacts frame while causing being with steel to enter circle shear, cause equipment breakdown.A major reason that produces this situation be with exactly steel from process section out, very long distance is to move on parallel roller-way, and owing to lacking tension force, band steel can freely swing, add the amplification with steel drift angle, cause circle shear below normally to work.Therefore, correcting is the key of dealing with problems with the skew on steel rider road.
Utility model content
The technical problems to be solved in the utility model is, lacks the tension force defect that causes circle shear normally to work that freely swings for existing in prior art because move on parallel roller-way with steel, and a kind of steel automatic deviation correction roller-way of being with is provided.
The utility model solves the technical scheme that its technical problem adopts:
The utility model provides a kind of band steel automatic deviation correction roller-way, comprise roller bed frame, running roller seat and roll assembly, described running roller seat is fixedly installed in roller bed frame, at least one pair of roll assembly is symmetricly set on running roller seat along the center line of unit band steel operation, described roll assembly comprises rolling axle, axle sleeve, bearing and baffle ring, described bearing is arranged on rolling axle, described axle sleeve is sleeved on rolling axle, described baffle ring is arranged between the outer end and axle sleeve of bearing, the two ends of described rolling axle are arranged on running roller seat, angle between the center line of the axis of described rolling axle and the operation of unit band steel is 75 °~90 °.
By technique scheme, the two ends side of the being flat of described rolling axle, offers the square groove matching with described side's flat on described running roller seat.
By technique scheme, described roller bed frame comprises multiple channel-section steels, and described running roller seat is mounted by means of bolts on channel-section steel.
The utility model, there is following beneficial effect: the utility model is simple in structure, easy to use, its ingenious inclination running roller horizontal component that utilized, make to be with steel both sides to tend to all the time unit centre and move, thereby reach the object of automatic centering, can effectively reduce with the sideslip probability in steel course of conveying, avoid being with steel to freely swing, guarantee circle shear is normally worked.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the top view of Fig. 1.
Wherein: 1-baffle ring, 2-bearing, 3-rolling axle, 4-axle sleeve, 5-band steel, 6-roller bed frame, 7-channel-section steel, 9-running roller seat, 11-square groove.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
In preferred embodiment of the present utility model, as shown in Figure 1 and Figure 2, a kind of band steel automatic deviation correction roller-way, comprises roller bed frame 6, running roller seat 9 and roll assembly.Running roller seat 9 is fixedly installed in roller bed frame 6, and roller bed frame 6 comprises multiple channel-section steels 7, and running roller seat 9 is mounted by means of bolts on channel-section steel 7.At least one pair of roll assembly is symmetricly set on running roller seat 9 along the center line of unit band steel operation.Roll assembly comprises rolling axle 3, axle sleeve 4, bearing 2 and baffle ring 1, bearing 2 is arranged on rolling axle 3, axle sleeve 4 is sleeved on rolling axle 3, baffle ring 1 is arranged between the outer end and axle sleeve 4 of bearing 2, the two ends of rolling axle 3 are arranged on running roller seat 9, axle sleeve 4, rolling axle 3, bearing 2 and baffle ring 1 are assembled into running roller free to rotate, the two ends side of the being flat of rolling axle 3, on running roller seat 9, offer the square groove 11 matching with the party's flat, the two ends of rolling axle 3 are arranged in the square groove of running roller seat, when rolling axle 3 is installed, must be splayed along unit band steel Operation Centre line is arranged symmetrically with, horizontal direction roll surface is smooth, arrange evenly, angle β between the center line of the axis of rolling axle 3 and the operation of unit band steel is 75 °~90 °, according to production line actual needs, can select some to rolling axle longitudinal arrangement, its incline direction is with corresponding with the direction of motion of steel 5.
Operation principle of the present utility model is: in the time of band steel 5 this roller-way of process, roller-way is under band steel frictional force drives, generation rotatablely moves, be in tilted layout because roller-way is, be subject to all the time pointing to the horizontal component of unit centre with steel 1 both sides, in the time of strip running deviation, one side band steel contact running roller is more, the horizontal component producing with steel is also larger, and band steel will move from trend unit centre direction, produces new balance to arriving.
The ingenious principle of dynamics of having used of the utility model, makes with steel under the effect of horizontal component, and trend band steel centerline direction moves all the time, reaches the effect of automatic deviation correction.The utility model apparatus structure is simple, easy to use, effectively reduces with the sideslip probability in steel course of conveying, has application value widely.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
