Abstract
The invention discloses a kind of straightener inlet guide and guards, including base (1), stand (2) and guide and guard horn mouth (4), bar (5) passes from guide and guard horn mouth (4), and described guide and guard horn mouth (4) is arranged on described stand (2) by bearing (3).Use technique scheme, the circumferential stress brought because of bending bar and C-shaped channel friction can be greatly reduced；The power that bar is subject to, from axial rub, circumference friction and three power of radial pressure, is reduced to only axial rub, radial pressure and less circumferential frictional force, size with joint efforts is made to significantly reduce, thus eliminate aligning impression, improve product quality, extension device life-span；Reduce parameter regulation difficulty during large scale rod bar aligning.
Description
Technical field
The invention belongs to the technical field of Rolling production equipment during steel and iron industry produces.More particularly it relates to
A kind of straightener inlet guide and guards.
Background technology
Seven roller straighteners are during aligning bar, and inlet guide is a kind of device being fixed on stand, plays and draws
Leading steel and enter correctly into the purpose of smoothing roll, inlet guide does not just have any effect afterwards, controls bar and enters rod after straightener
The swing of material afterbody is completely by the restriction of C-shaped channel.
As depicted in figs. 1 and 2, whole guide and guard horn mouth 4 is an entirety, fixes with stand 2 and is connected, non-rotatable.
If the flexibility of steel 5 is too high and specification is relatively big, relatively big with C-shaped channel 8 or bell-mouthed frictional force, then can
Aligning impression occurs.I.e. affect the quality of product, again equipment is caused damage；Meanwhile, in process of production, the regulation of equipment is difficult
Spend the biggest.
Summary of the invention
The present invention provides a kind of straightener inlet guide and guards, its objective is the friction reducing bar with inlet guide.
To achieve these goals, the technical scheme that the present invention takes is:
The straightener inlet guide and guards of the present invention, including base, stand and guide and guard horn mouth, bar is from guide and guard horn mouth
In pass；Described guide and guard horn mouth is arranged on described stand by bearing.
Described guide and guard horn mouth is two or more of coaxial line distribution.
On each described guide and guard horn mouth, it is respectively provided with radial bearing and thrust bearing.
Described stand is arranged on described base by guide mounting frame.
Described guide mounting frame is vertical column, and described guide mounting frame is set with antirattle spring.
The present invention uses technique scheme, use double horn mouth guide and guards, and each horn mouth guide and guard can be around
Circumferencial direction rotates, and bar does not contacts with C-shaped channel during rotating forward, but contacts with rotatable guide and guard, from
And the circumferential stress brought because of bending bar and C-shaped channel friction can be greatly reduced；The power that bar is subject to, from axial rub, circumference
Friction and three power of radial pressure, be reduced to only axial rub, radial pressure and less circumferential frictional force, and make with joint efforts is big
Little significantly reduce, thus eliminate aligning impression, improve product quality, extension device life-span；Reduce when large scale rod bar is aligned
Parameter regulation difficulty.
Accompanying drawing explanation
Content shown in accompanying drawing and the labelling in figure are briefly described as follows:
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structure diagram of prior art；
Fig. 3 is the structural representation of the present invention；
Fig. 4 is the structure diagram of the present invention.
Figure is labeled as:
1, base, 2, stand, 3, bearing, 4, guide and guard horn mouth, 5, bar, 6, antirattle spring, 7, guide mounting frame, 8,
C-shaped channel.
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Illustrate, to help those skilled in the art that inventive concept, the technical scheme of the present invention are had more complete, accurate and deep reason
Solve.
The structure of the present invention as shown in Figure 3, Figure 4, for a kind of straightener inlet guide and guards, including base 1, stand 2 and
Guide and guard horn mouth 4, bar 5 passes from guide and guard horn mouth 4.It is mainly used in seven roller straighteners.The present invention is that design one is led
Rotatable device of defending, to coordinate the use of straightener, eliminates aligning impression.
In order to overcome the defect of prior art, it is achieved reduce the goal of the invention of bar and the friction of inlet guide, the present invention
The technical scheme taked is:
As shown in Figure 3, Figure 4, the straightener inlet guide and guards of the present invention, described guide and guard horn mouth 4 is pacified by bearing 3
It is contained on described stand 2.
Originally fixing guide and guard horn mouth 4 is replaced improvement, first bearing 3 is fixed on the stand 2 of base 1,
Guide and guard horn mouth is mounted in bearing, and such guide and guard horn mouth 4 can be along central axis；And by with a C-shaped channel
Place also replaces to the horn mouth that bore is bigger.
Utilize seven roller straightener inlet guides of technique scheme, can effectively reduce or eliminate large scale rod bar and exist
From the circumferential frictional force of smoothing roll in straightening process, it is possible to reduce parameter regulation difficulty during large scale rod bar aligning, eliminate
The aligning impression occurred during big specification curved steel aligning.Especially for the bar of bending, its effect becomes apparent from.
Described guide and guard horn mouth 4 be distributed for coaxial line two or more.Guide and guard quantity increases, and can be two
Or two or more；Each guide and guard, for rotating vertically, reduce the stress of each guide and guard, make stress be more uniformly distributed, particularly
Reduce the circumferential frictional force that impact is maximum, reduce aligning impression, improve the quality of product；Meanwhile, the stress of equipment is also obtained
Improve, extend its service life.
On each described guide and guard horn mouth 4, it is respectively provided with radial bearing and thrust bearing.
Radial bearing is for bearing the radial force of bar 5；Thrust bearing is for bearing bar in forward movement
Axial force.
Described stand 2 is arranged on described base 1 by guide mounting frame 7.
By guide mounting frame 7, the height of stand 2 can be regulated, and, each guide and guard horn mouth 4 is arranged on difference
Guide mounting frame 7 on, so the position of each guide and guard horn mouth 4 can individually regulate.
Described guide mounting frame 7 is vertical column, and described guide mounting frame 7 is set with antirattle spring 6.With
In reducing the vibrations that bar 5 produces at straightening process, to ensure that equipment is the most impaired, also improve the quality of product.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the method design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or without changing
Enter and design and the technical scheme of the present invention are directly applied to other occasion, all within protection scope of the present invention.
