Abstract
The utility model discloses a roller way with centering function, the roller way is formed by two rows of roller ways symmetrically arranged according to the central line of the roller ways, angles are deflected between the rollers of the two roller ways and the central line of the roller ways, and the deflection angles are identical; the axle lines of the two parallel roller ways are symmetrically arranged through presenting an inverted ''Y'' shape. When the band steel deflects toward to the left side, the contacting area of the roller ways at the left side and the lower surface of the band steel is increased, the contacting area of the roller ways at the right side and the lower surface of the band steel is reduced, the thrust force of the roller ways applied to band steel is larger than the thrust force to the left side, thus, the band steel can be trusted to the right side, conversely, the band steel can be trusted to the left side. The automatic deflection improvement is performed to the position of the band steel ceaselessly during the transportation process of the band steel (or plate blank), to ensure that the band steel runs along the central line of the roller ways.

Referring to Fig. 1, common roller-way 10 is simple in structure, but roller-way self does not possess the centering function, and the deviation phenomenon of moving about along about the roller-way center line often appears in band steel (or slab) 20 when move on roller-way 10, so must design roller-way backplate 30 in roller-way limit portion.Its shortcoming is that the roller-way backplate only can prevent to be with steel to deflect away from roller-way, can not solve the move about problem of band steel in the roller-way width range.
The band steel freely moves about in the backplate scope and can cause following problem:
1. can clash into the roller-way backplate during band steel (or slab) sideslip, serious even cause the backplate distortion;
2. be with steel (or slab) meeting wearing and tearing backplate;
3. behind the bump backplate, the speed of service of band steel can change, and causes speed or follows the tracks of mistake in computation;
4. behind the generation sideslip, need to use driving or special equipment that band steel or slab are rectified a deviation, influence rhythm of production;
5. may influence the certainty of measurement of instrumentations such as profile gauge, width instrument, even can cause measurement mechanism to lose efficacy;
6. the band steel enters down operation with the state of sideslip, may cause piling the steel accident and take place.
Referring to Fig. 2, Fig. 3, adopt the drift angle to arrange roller-way in addition, the axis of the every roller 101 of drift angle layout roller-way 10 (to call the drift angle roller-way in the following text) and the angle of cut of roller-way center line are not 90 degree.When the special deflection cloth postpone of roller quilt, the roller of rotation resolves into two component f1 and f2 to the tangential force F that band steel 20 (or slab) applies, and wherein f1 is the thrust along the roller-way centerline direction, and f2 is the thrust towards side direction, their size is respectively f1=F*cosa, f2=F*sina.Angle of deviation a is big more, and is big more towards the thrust of side direction.The purpose of its design is to make roller-way 10 when rotation promotes band steel (or slab) forward, form towards the branch of a side to thrust, make its guide plate that is adjacent to this side 40 operations.And this guide plate steel going along with (or slab) wide variety and changing is advanced along the roller-way center line all the time to guarantee it.But there is following shortcoming in this guide plate design:
1. to guarantee to be with steel (or slab) all the time along the rolling centerline operation, must be at the adjustable long guide agency of a kind of aperture of roller-way one side matching design, input cost is far above the uncontrollable roller-way backplate of aperture
2. the band steel is close to side operation, the serious wear of flipper guide.
Summary of the invention
The purpose of this utility model is to design a kind of roller-way with centering function, realizes the automatic centering function of band steel (or slab); With the sideslip that reduces band steel (or slab) and to problems such as the wearing and tearing of backplate or bump, the centering requirement when satisfying instrumentation to band steel (or slab) operation.
For achieving the above object, the technical solution of the utility model is,
A kind of roller-way with centering function, this roller-way is made up of by the symmetrical institute that is provided with of roller-way center line two row's roller-ways, the roller of this two roller-way and roller-way center line deflection one angle [alpha], and deflection angle equates; The axis of two rollers arranged side by side is " people " font symmetric arrangement.
Described skew angle is 3～6 degree.
The left side roller-way is implemented a branch to the right to thrust to the band steel, and the right side roller-way is implemented a branch to the left to thrust to the band steel.When the band steel when the roller-way center line moves, two side-thrusts are equal substantially.
In band steel (or slab) transportation, constantly automatic deviation correction is carried out in its position, guarantee to be with steel to move along the roller-way center line.
The beneficial effects of the utility model
1. the utility model can guarantee to be with steel along the operation of roller-way center line by the taper roller-way, and the deviation phenomenon that reduces band steel (or slab) is had certain effect;
2. cancelled the adjustable flipper guide of the aperture mechanism of roller-way one side, reduced to build and drop into;
3. can reduce the problem of band steel or slab bump backplate, and reduce the backplate wearing and tearing;
4. can reduce the correction operation of band steel or slab, reduce non-programmed halt;
5. can reduce band steel toe portion sideslip and enter down the heap steel accident that operation causes;
6. can improve the measuring condition of measuring instrument, improve and detect quality.
The utility model can apply to transport the sheet material and the slab of all kinds of surface requirements, can not influence band steel following table quality.
The centering effect is subjected to the influence with the steel weight per unit area: we find in the long-term use of roller-way is arranged in the drift angle: belt steel thickness thick more (be on the unit are weight heavy more), roller-way to the branch that applies of band steel to thrust big more, the effect that the band steel moves about to a side is obvious more.So the utility model is more suitable for being used to transport thicker rolled pieces such as slab or slab.
