Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As it can be seen, four roller continuous pipe rolling mills described in the present embodiment, including tunnel type memorial archway 1 and along tunnel type memorial archway 1 central shaft Many groups rolling machine frame 2 that line sets gradually, is often equipped with four groups of roll assemblings 3 in group rolling machine frame 2, each roll assembling 3 is respectively Connect one group of roll gap adjustment device 4 assembling 3 roller gaps for regulating roll, rolling machine frame 2 is additionally provided with and is available for rolling Frame 2 is along the changing rig of tunnel type memorial archway 1 central axial direction back and forth movement;Wherein roll gap adjustment device 4 is fixed on tunnel On formula memorial archway 1, such roll gap adjustment device 4 has consistent rigidity in the radial direction at tunnel type memorial archway 1, can make roll gap The anglec of rotation of adjusting means 4 is corresponding with the anglec of rotation of roll axis, it is ensured that can accurately realize each roller gap Independent effectively control.
Rolling machine frame 2 includes odd stands and even number frame, described odd stands and the even number frame center along tunnel type memorial archway 1 Axis Cross is arranged, in the four groups of rolls assembling 3 in the most each odd stands, the roll axis of two groups of roll assemblings 3 relative to The horizontal center line of tunnel type memorial archway 1 deflects 22.5 °, and the roll axis of other two groups of rolls assembling 3 is relative to tunnel type memorial archway The vertical centrage of 1 deflects 22.5 °;In each even number frame, the roll axis of two groups of roll assemblings 3 is relative to tunnel type memorial archway 1 Horizontal center line reversely deflect 22.5 °, vertical relative to tunnel type memorial archway 1 of the roll axis of other two groups of rolls assembling 3 Centrage reversely deflects 22.5 °;Odd stands topping roll assembling 3 is similar roll assembling 3 with even number frame topping roll assembling 3, During layout, only direction and angle are different, and odd stands rotates 180 ° around horizontal center line or the vertical centrage of tunnel type memorial archway 1, Can be consistent with the roll pass of even number frame, improve the interchangeability between frame.
Preferably, the rolling angle of each roll assembling 3 envelope 90 ° respectively in same rolling machine frame 2, lower single rolling Envelope angle processed, can improve the concordance of circumferencial direction speed when seamless steel pipe is rolled, when reducing metal flow should Power and strain, the deformation uniformity making tubing circumference is more preferable.
In the present embodiment, the rolling angle of each roll assembling 3 envelope 90 ° respectively, it is relative that each roll on odd stands assembles 3 Horizontal center line or vertical centrage in tunnel type memorial archway 1 deflect 22.5 ° counterclockwise, and the roll assembling 3 in even number frame is then Deflection 22.5 ° clockwise, when carrying out roll and exchanging, odd stands rotates 180 ° around the centrage of tunnel type memorial archway 1 Consistent with the roll pass of even number frame.
In the present embodiment, each roll assembling 3 connects one group of drive system respectively, and wherein drive system includes that be fixedly installed drives Moving device 5 and be connected to the shaft coupling 6 between driving means 5 and roll assembling 3, shaft coupling 6 is by the power of driving means 5 Being transported in each roll assembling 3 of rolling machine frame 2, often the assembling 3 of group roll is by independent transmission system drives, it is ensured that every Individual roll can synchronized rotation actively.
The locking positioning block 7 for positioning and locking rolling machine frame 2 and locked hydraulic cylinder 8 it is provided with in tunnel type memorial archway 1;In this reality Executing in example, tunnel type memorial archway 1 top corresponding to each rolling machine frame 2 is provided with four and determines for positioning the locking of rolling machine frame 2 Position block 7, these four locking positioning blocks 7 are distributed in the vertical centrage both sides of tunnel type memorial archway 1, the locking positioning block 7 of side For realizing the rolling machine frame 2 location at vertical direction, the locking positioning block 7 of opposite side is used for realizing rolling machine frame 2 in level The location in direction;Tunnel type memorial archway 1 bottom is provided with four locked hydraulic cylinders upwards pushed up 8, and rolling machine frame 2 moves to location Behind place, four locked hydraulic cylinders 8 push up rolling machine frame 2, promote rolling machine frame 2 to move straight up, when on rolling machine frame 2 Locating surface with on tunnel type memorial archway 1 arrange four locking positioning blocks 7 contact after, i.e. lockable locked hydraulic cylinder 8, it is achieved The rolling machine frame 2 location in tunnel type memorial archway 1 and locking.
The present invention is to realize the roll change action of roll assembling 3, therefore, changing in the present embodiment by moving axially rolling machine frame 2 The track 10 that roller arrangement slides for guide wheel 9 in including guide wheel 9 and being correspondingly arranged at described tunnel type memorial archway 1;Guide wheel 9 is arranged on On rolling machine frame 2, for ensureing the guide wheel 9 stability in sliding process, below each rolling machine frame 2 in the present embodiment all Being provided with four guide wheels 9, four guide wheels 9 are distributed in the vertical centrage both sides of tunnel type memorial archway 1, wherein two guide wheels 9 of side For flute profile guide wheel, two guide wheels 9 of other side are flat guide wheel, and below tunnel type memorial archway 1, the vertical centrage left and right sides is corresponding Arrange a channel suspending rail, a plate rail road, after rolling machine frame 2 is moved along tunnel type memorial archway 1 axis direction, Ji Kejin Row roll assembles the associative operations such as 3 replacings.
Finally illustrating, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although by above-mentioned The present invention is described in detail by preferred embodiment, it is to be understood by those skilled in the art that can in form and In details, it is made various change, without departing from claims of the present invention limited range.
