It is arranged mutually staggered along aligning gap, is guided the material that must be aligned in the form of serpentine and passes through aligning gap,
And the material to be aligned in the process is alternately bent up and down on straightening roll.Middle curve form can be to make
Obtaining material and being bent at least on the first straightening roll is more than its limit of stretch, to completely eliminate as far as possible undesirable curved in material
Bent and stress.Strong plastic deformation occurs on the first straightening roll for the usual material.The material on remaining roller
Bending it is weaker, and the material is no longer plastically deformed on last straightening roll, that is to say, that flexible deformation only occurs.
In metal-processing industry, usually using metal tape, this metal tape is provided with plate-like, and right in order to produce
The disk-like structure is unwound.By the way that strip material is wound into disk, it is also possible to due to carry out in advance it is possible heat at
Reason or similar operations will appear unevenness or stress in strip material, and the unevenness or stress are not for continuing processing
Benefit.Therefore, after usually being unwound the metal tape of disk-like structure, between the aligning that guide metal tape to pass through straightener
Gap, and the metal tape is made to leave the aligning gap flat and unstressedly.
But this is not unique purposes, because the straightener of above structure is also used to align flat metalwork, Ying Cong
Undesirable bending and stress are removed on the metalwork, so as to continue to process the metalwork.Especially in this portion
In part straightener, very big advantage is realized through the invention.
The straightener of structure as described above is for example as disclosed in EP-A-2 712 687.This disclosed straightener is equally special
Flat metalwork Shi Yu not aligned and solved the problems, such as follows.That is, when connecting upper roller frame and lower roller frame by positioning bolt
When, the aligning gap of straightener can broaden in straightening process.According to this prior art suggestion, positioning bolt is equipped with for changing
The regulating device for becoming the effective length of positioning bolt, so that the change of positioning bolt effective length can be compensated in real time in operation
Change, positioning bolt is usually elongated under load effect.
Other above-mentioned straighteners are for example by the EP-A-2 002 907 more particularly to the transmission system for straightener
And as disclosed in EP-A-1 491 270.
The straightening roll of the straightener of this structure usually on an end side have linkage element, for driving device
Universal axis connection.The linkage element is normally constructed to the connection axle journal with exterior contour.In the positioned opposite of straightening roll
End side is equipped with the bearing journal for the axial bearing being used as in corresponding roller frame.In order to take out straightening roll from roller frame, in driving side
Universal shaft is extracted from straightening roll, dismantle affiliated supporting portion and extract straightening roll from opposite supporting portion out.
The straightening roll of the straightener of above structure will receive very strong power and therefore can occur to a certain extent quickly
Abrasion.When the abrasion of straightening roll reaches the degree that meeting leave visual defects on the surface of the metal tape or metalwork to be aligned
When, then it must replace straightening roll.Since straightening roll needs high stability, intensity and dimensional stability, correspondingly straightening roll is more
Changing required cost can be very high.
Summary of the invention
Therefore, the purpose of the present invention is to propose a kind of straightener of type described above and a kind of rectify for operating this
The method of straight machine, especially when straightener using the straightener or the method for that can be mentioned when aligning flat metalwork
The service life of high straightening roll.
The purpose is by the straightener of feature with claim 1 a kind of and passes through the spy with claim 12
The method of sign is realized.The preferred embodiment of straightener according to the present invention provides in claim 2 to 11；According to this
The scheme that is advantageously improved of the method for invention provides in claim 13 to 15.
It recognizes according to the present invention, the straightening roll for aligning flat metalwork of straightener is filled in straightener and driving
Setting side positioned opposite can rapidly wear.This is relevant to following facts: operator operates straightener and leads to
Often by the roller-way that the metalwork to be aligned is placed on front side of the entrance of straightener or other conveying devices, and it is sent to
The entrance, operator need to rest on the side opposite with driving device of straightener thus.Certainly, if the gold to be aligned
Category part is narrower than the width of entrance, then the metalwork is not usually placed in the middle, and is proximate to operator, that is to be aligned
Metalwork enters aligning gap backwards to the side of driving device from straightener.This will lead to straightening roll in the fore side ratio of straightener
Driving side is more rapidly worn.
In addition, according to the present invention it is also recognized that in straightening roll by this asymmetric load and mainly one
When straightening roll abrasion occurs for side, the service life of straightening roll can be improved by very simple mode as follows.That is, aligning
