Abstract
The present invention relates to a kind of against shock mechanisms of sheet rolling mill, Vibration proof rolling mill is formed by mill housing, backing roll, working roll and back-up chock, working roll bearing block, backing roll and working roll are tightly placed in respectively in back-up chock and working roll bearing block, and back-up chock, working roll bearing block are installed on mill housing.The deviation of backing roll installation site opposing work roller installation site is identical as rolling direction, i.e. the eccentricity of the working roll line of centres is opposite with rolling direction.The present invention makes sheet metal, and milling train phenomenon without friction occurs during the rolling process, not only can be improved outside sheet metal rolling quality, mill speed also can be improved.
Description
Technical field
It is the invention belongs to the milling train field for rolling metal strip, in particular to a kind of applied to a kind of sheet rolling mill
Against shock mechanism.
Background technique
In sheet metal production process, especially in a thickness of 2.6 millimeters of sheet metal productions below, rolling mill vibration is
One seriously affects mill capacity and plays and the problem of product quality, so it is one urgently to be resolved that control sheet mill, which vibrates,
Problem.Currently, sheet mill is mainly by mill housing, backing roll, back-up chock, working roll, working roll bearing block
Deng composition, to realize that Rolling roller sews on the adjusting of the spacing between bottom working roll, have between heel post in working roll bearing block and memorial archway
0.3 millimeter or so of gap, in addition to realize to the stable supports of upper working rolls and lower working rolls, in the upper working rolls and lower working rolls of sheet mill
Relatively the center of support shaft is connected toward general 10 millimeters of rolling direction deviation heart line up and down.In the sheet metal operation of rolling, rolled piece
(i.e. sheet metal) bears rolling tensile force T1, T2 before and after rack, usual T1 > T2.Because of the symmetry of structure, in order to make to roll
Rolled piece stabilization rolls forward in journey, and working roll must provide a forward horizontal drag force, and value is the difference of T1 and T2；Accordingly
Region is rolled on ground working roll and then bears the horizontal component T of a direction backward, and T is equal to the difference of T1 and T2.Because supporting roll shaft
Holding seat is static-pressure sliding bearing, it does not generate the moment of resistance when rotating substantially, it is believed that backing roll is to the supporting force of working roll
One by the power P of work roller center, the horizontal component Ph and roll-force water of working roll main supported roller pressure in the horizontal direction
Divide power T equally, the two is contrary.When Ph is greater than T, working roll bearing block is close to forward on the inside of memorial archway；When Ph is less than T, work
Make roll bearing seat to be close to backward on the inside of memorial archway, when Ph and T are roughly equal, because of rolling deformation drag, rolling zone in the operation of rolling
The resultant direction of the continuous variation of domain coefficient of friction, Ph and T will neglect forward or neglect backward, and working roll bearing block will front and back fortune
It is dynamic, memorial archway rack is impacted, rolling mill vibration is caused, influences sheet metal rolling.
Summary of the invention
It is an object of the invention to overcome the above-mentioned prior art, a kind of against shock mechanism of sheet rolling mill is provided,
The upper and lower backing roll riding position of the device is different, and structure changes, and milling train does not generate vibration during sheet metal.
The present invention is achieved by the following technical solutions:
A kind of against shock mechanism of sheet rolling mill is by mill housing, backing roll, working roll and back-up chock, working roll
Bearing block forms Vibration proof rolling mill, and backing roll and working roll are tightly placed in respectively in back-up chock and working roll bearing block, and are propped up
Runner bearing block, working roll bearing block are installed on mill housing.Backing roll installation site opposing work roller installation site it is inclined
To identical as rolling direction, i.e. the eccentricity of the working roll line of centres is opposite with rolling direction.
Beneficial effects of the present invention:
It is an advantage of the invention that the sheet metal Vibration proof rolling mill made of technical solution as above, great advantage is sheet metal
Milling train phenomenon without friction occurs during the rolling process, not only can be improved outside sheet metal rolling quality, mill speed also can be improved.
Detailed description of the invention
Fig. 1 is schematic view of the mounting position of the invention.
In figure, 1 be mill housing, 2 be backing roll, 3 be back-up chock, 4 be working roll, 5 be working roll bearing block,
6 be rolled piece.
Specific embodiment
Below according to attached drawing, 1 couple of present invention is described in detail；
As shown in Figure 1, Vibration proof rolling mill is by mill housing l, backing roll 2, back-up chock 3, working roll 4, work roll shaft
The composition of seat 5 is held, backing roll 2 and working roll 4 are tightly placed in back-up chock 3 and working roll bearing block 5, back-up chock 3
And working roll bearing block 5 is mounted on mill housing 1.The installation site of backing roll 2 relative to working roll 4 installation site it is inclined
To identical as rolling direction, i.e. 10 millimeters of one parasang of line of centres skew of the line of centres of working roll 4 and backing roll 2,
The eccentricity of 4 center line of working roll is opposite with rolling direction.Backing roll 2 mutually supports rolled piece 6 with working roll 4 during the rolling process
Disappear, can avoid the rolling mill vibration because caused by constantly changing its Impact direction.
