Description
Technical field
The utility model relates to technical field of steel rolling, particularly belong to a kind of pinch roller.
Background technique
Pinch roller is the important accessory of one of steel manufacturing equipment, and clamping is especially played in the production of strip, is drawn
The effects of stretching and conveying.In the prior art, the material wear ability that pinch roller mostly uses greatly is not high to be prone to wear, and is needed after abrasion
New pinch roller is replaced, pinch roller replacement at present is using whole replacement, so as to cause increased costs.Therefore a kind of folder how is designed
Roller is sent to reduce replacement cost, is technical problem urgently to be solved.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of pinch roller.
The utility model adopts the technical scheme that
A kind of pinch roller, including roll body, the collars being fixed on outside roll body and bolt for connecting roll body, collars, wherein
The roll body is in the form of a column, the roll body include outer spindle, the support shaft below outer spindle and below support shaft in
Spindle, the support shaft are greater than the outer spindle outer diameter and the interior spindle outer diameter, and the collars includes inner ring and outer rings, described
Inner ring is located at outer ring inner wall, and the outer ring outer wall is equipped with several grooves, is equipped with solid lubricant in the groove.
Preferably, feed opening is equipped among the roll body.
Preferably, the groove is arcuation slot.
Preferably, the support shaft is equipped with threaded hole.
Preferably, the inner ring is equipped with threaded hole.
Preferably, the inner ring internal diameter is consistent with the interior spindle internal diameter.
Preferably, the bore diameter of outer ring is consistent with the support shaft internal diameter.
Preferably, the collars material is antifriction alloy.
Compared with prior art, the utility model has the beneficial effects that being ground using collars and roll body detachable structure
When damage, directly replaces collars and retain roll body, certain cost can be saved；Groove is set on collars simultaneously and stores solid profit
Lubrication prescription can further decrease abrasion, reduce replacement number.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only

Specific embodiment
It is with reference to the accompanying drawing and specific real in order to make those skilled in the art better understand technical solution of the present invention
Applying mode, the present invention is described in further detail.
As shown in Figure 1 and 2, a kind of pinch roller include roll body 1, the collars being fixed on outside roll body 12 and for connect roll body 1,
The bolt 3 of collars 2.Pinch roller is Demountable, can be by independent when the collars 2 on the outside of pinch roller is worn
Collars 2 is replaced, and does not have to replace entire pinch roller, therefore save cost.Meanwhile roll body 1 and collars 2 are fixed by bolt 3,
It is convenient to dismantle.In addition, collars 2 uses more wear resistant alloy material, replacement number can also be reduced.
As shown in Fig. 3 ~ 4, roll body 1 is in the form of a column structure comprising outer spindle 11, the support shaft positioned at outer 11 lower section of spindle
12, the interior spindle 13 below support shaft 12 and the feed opening 14 being arranged among roll body 1.Outer spindle 11 is for connecting outside
Mechanical equipment, support are taken out 12 and are used to support on collars 2.Wherein, 12 outer diameter of support shaft is greater than outer 11 outer diameter of spindle and institute
Interior 13 outer diameter of spindle is stated, and threaded hole is set in support shaft 12.Collars 2 includes inner ring 21 and outer ring 22, and inner ring 22 is located at outer
21 inner wall of ring.Threaded hole is provided in inner ring 22, and 21 internal diameter of inner ring is consistent with interior 13 internal diameter of spindle, bore diameter of outer ring 22 and support
13 internal diameter of axis is consistent, and such roll body 1 can be embedded just below inside collars 2.In addition, 21 outer wall of outer ring is equipped with 4 grooves 23, it is recessed
23 shape of slot is arc, and solid lubricant is equipped in groove 23.Solid lubricant can reduce the abrasion of 2 outer surface of collars
Degree, to reduce replacement number.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
It is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein and inventive features phase
Consistent widest scope.
