Description
Technical field
The utility model relates to a kind of straightener variable diameter straightening roller devices.
Background technique
Sheet metal is often deformed in production, manufacture, transport and management process, influences its service performance, because
This needs to carry out straightening processing to sheet metal using some special methods, to guarantee the straightness of plate face.Existing enterprise pair
The aligning of sheet metal mostly uses greatly following several method: (1) being flattened using press machine to thin plate, this method is for rebound
Good, the too thin sheet metal of plate of property, effect are bad；(2) thin plate, this method, for too thin are aligned using the method being straightened
Plate, it is not easy to clamp, and due to the effect of clamping force, can also damage plate face in the place of clamping, influence the use of thin plate,
The thin plate big for plate face, will clamp whole side, and it is also extremely difficult to align entire plate face；(3) using roll leveller aligning gold
The roller diameter of metal thin plate, used roll leveller, the straightening roll of use is identical, in the case where hightension, since strip can be tight
It being attached on straightening roll, the residual stress inside strip can not be discharged changing the inclination angle of replaceable straightening roller system, leveling effect is bad,
It cannot get high straight plate face, be extremely difficult to the requirement of production plate.
Utility model content
In view of the foregoing drawbacks, easy to operate the purpose of this utility model is to provide a kind of structure is simple, it can release very well
Put strip internal residual stress, a kind of good straightener variable diameter straightening roller device of leveling effect.
Thus the technical scheme adopted by the utility model is
Including rack, upper roller frame, lower roll frame and down pressing oil cylinder, the down pressing oil cylinder is mounted on the rack end, described
The lower end of down pressing oil cylinder is fixedly connected with upper roller frame, and the upper roller lower portion is several equipped with arranging along plate direction of advance
Upper correct roller, is equipped with several lower correct rollers matched with upper correct roller in the lower roll frame, several upper correct rollers with
The roller diameter of several lower correct roller interleaveds arrangements, several upper correct rollers and several lower correct rollers along plate direction of advance by
Gradual change is big, and the lower end surface of several upper correct rollers is in same level, and the upper surface of several lower correct rollers is same
On horizontal plane.
As a further improvement of the above technical scheme, it is equipped on several between several upper correct rollers and upper roller frame
Backing roll.
As a further improvement of the above technical scheme, between several lower correct rollers and lower roll frame be equipped with it is several under
Backing roll.
As a further improvement of the above technical scheme, between several tops backing up roll and several upper correct rollers and several
Several intermediate calender rolls are equipped between lower support roll and several lower correct rollers.
The utility model has the advantages that:
The utility model structure is simple, easy to operate, by using the utility model structure, several upper correct rollers with it is several
The roller diameter of lower correct roller becomes larger along plate direction of advance, can discharge strip internal residual stress very well, to realize very
Good leveling effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is rack in figure, 2 be upper roller frame, 3 be lower roll frame, 4 be down pressing oil cylinder, 5 be upper correct roller, 6 is lower correction
Roller, 7 be top backing up roll, 8 be lower support roll, 9 be intermediate calender rolls.
Specific embodiment
A kind of straightener variable diameter straightening roller device, including rack 1, upper roller frame 2, lower roll frame 3 and down pressing oil cylinder 4,
The down pressing oil cylinder 4 is mounted on 1 upper end of rack, and the lower end of the down pressing oil cylinder 4 is fixedly connected with upper roller frame 2, the upper roller
It is equipped with several upper correct rollers 5 arranged along plate direction of advance inside frame 2, is equipped with and upper correct roller 5 in the lower roll frame 3
Several lower correct rollers 6 matched, several upper correct rollers 5 are arranged with several lower 6 interleaveds of correct roller, it is described it is several on
Correct roller 5 and the roller diameter of several lower correct rollers 6 become larger along plate direction of advance, the lower end surface of several upper correct rollers 5
In same level, the upper surface of several lower correct rollers 6 is in same level.
As a further improvement of the above technical scheme, it is equipped between several upper correct rollers 5 and upper roller frame 2 several
Top backing up roll 7.
As a further improvement of the above technical scheme, it is equipped between several lower correct rollers 6 and lower roll frame 3 several
Lower support roll 8.
As a further improvement of the above technical scheme, if between several tops backing up roll 7 and several upper correct rollers 5 and
Several intermediate calender rolls 9 are equipped between dry lower support roll 8 and several lower correct rollers 6.
It is emphasized that: the above description is only the embodiments of the present invention, is not intended to limit the utility model
The scope of the patents, equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, or it is straight
It connects or is used in other related technical areas indirectly, be also included in the patent protection scope of the utility model.
