It is provided with rack water pipe 3 (as shown in Figure 1)；More conventional frame water pipe 3 uses18 × 2 copper tube, with the shape of roll stand 1
Shape setting is in shell outside, and connector is more and shape is more complicated.It is mobile frequent since roll stand 1 needs often to overhaul,
Rack water pipe 3 collides with to deform frequent occurrence and even reveal；Poor with water cleannes additionally, due to scene, rack water pipe 3 is easy quilt
Blocking, dredging are repaired relatively difficult.In 2 cooling procedure of roll, if discharge reduction or water shortage will lead to roll, 2 roll surface is split
Line, crack even cracking phenomena easily cause hot seamless tube bending defect simultaneously because cooling effect is bad, make normally to produce
Rhythm is destroyed.
Summary of the invention
The present invention provides a kind of cooling hydrosphere of hot seamless tube sizing roll, using removable cooling hydrosphere, according to making
With needing to configure, the configuration quantity and maintenance capacity of rack are not only reduced, and caused by avoiding and frequently overhauling because of roll stand
Cooling hydrosphere damage, guarantee water-cooled effect.
In order to achieve the above object, the present invention is implemented with the following technical solutions:
A kind of cooling hydrosphere of hot seamless tube sizing roll, including cooling hydrosphere, the cooling hydrosphere are movably disposed
In gap between adjacent rollers rack；Cooling hydrosphere is made of hydrosphere, water inlet pipe, support rod one and support rod two, water
Circle one end is connect with horizontally disposed water inlet pipe, and water inlet pipe is connect by quick coupling with external water pipe；It is circumferential and right along hydrosphere
Two sides roll location is answered to be uniformly arranged multiple nozzles, and the multiple that the quantity of nozzle is 3；Support rod one, water inlet pipe are set on hydrosphere
On set support rod two, support rod one and support rod two to cooling water enclose it is high to and radial support positioning action.
The corresponding cooling hydrosphere position in the roll stand two sides sets locating piece, encloses axially position effect to cooling water.
One bottom of support rod sets idler wheel, can roll along the groove between adjacent rollers rack.
Two lower part of support rod sets rotatable locating rod, can be clamped on the inside of the drag hook by roll stand after rotation.
The opening direction of the nozzle is towards respective side roll.
Compared with prior art, the beneficial effects of the present invention are:
1) after using removable cooling hydrosphere, roll stand is not necessarily to fixed configurations, is deployed as needed in production
Installation, reduces spare part quantity, reduces production cost；
2) damage of roll stand when frequently overhauling mobile to cooling water pipe is avoided, guarantees water-cooled effect, is conducive to extend
Roll working life, and improve the lumber recovery of hot seamless tube；
3) cooling water coil structures are simple, easy to use.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
As shown in figs 2-4, the cooling hydrosphere of a kind of hot seamless tube sizing roll of the present invention, including cooling hydrosphere 4,
The cooling hydrosphere 4 is movably disposed in the gap between adjacent rollers rack 1 (as shown in Figure 3)；As shown in figure 4, cold
But hydrosphere 4 is made of hydrosphere 41, water inlet pipe 43, support rod 1 and support rod 2 47,41 one end of hydrosphere with it is horizontally disposed
Water inlet pipe 43 connects, and water inlet pipe 43 is connect by quick coupling 44 with external water pipe；The circumferential and corresponding two sides roll 2 along hydrosphere 41
Position is uniformly arranged multiple nozzles 42, and the multiple that the quantity of nozzle 42 is 3；Support rod 1, water inlet pipe 43 are set on hydrosphere 41
On set support rod 2 47, support rod 1 and 2 47 pairs of support rod cooling hydrospheres 4 rise it is high to and radial support positioning action.
Corresponding cooling 4 position of hydrosphere in 1 two sides of roll stand sets locating piece, plays axially position to cooling hydrosphere 4.
One 45 bottom of support rod sets idler wheel 46, can roll along the groove between adjacent rollers rack 1.
2 47 lower part of support rod sets rotatable locating rod 48, and the drag hook 5 on 1 side of roll stand can be clamped on after rotation
Inside.
The opening direction of the nozzle 42 is towards respective side roll 2.
As shown in Figure 1, sizing mill is the equipment that will carry out fixed diameter rolling after the heating of the steel pipe after breaking down, for making steel pipe
Obtain the outer dimension of degree of precision.Sizing mill is mainly made of roll stand 1 and transmission device, and multiple roll stands 1 are along vertical
To being sequentially arranged on unsplit bedplate, 2 axis of roll in adjacent 2 roll stands 1, which interlocks 60 °, to be arranged；According to institute's rolled steel
The quantity of the dimensions of pipe, the roll stand 1 passed through is different；When carrying out water cooling using conventional structure, each roller mill
Frame 1 must configure rack water pipe 3.
As shown in Fig. 2, the present invention uses the cooling hydrosphere 4 of packaged type, during seamless pipe fixed diameter rolling, according to it
1 quantity of roll stand passed through determines the usage amount of cooling hydrosphere 4, and assembled cooling hydrosphere 4 is installed to adjacent rollers
In the crack of rack 1；When installation, cooling hydrosphere 4 is directed at crevice place, the idler wheel 46 of one 45 bottom of support rod is put into crack bottom
In the groove in portion, push is aligned 41 center of hydrosphere with 1 center of roll stand forward；Then 2 47 lower part of support rod is turned
Dynamic locating rod 48 is clamped on the inside of the boss at 5 top of drag hook after rotating downwards, and it is fixed to complete cooling hydrosphere 4；It then will water inlet
43 side of pipe is connected to by quick coupling 44 with external water pipe；When seamless pipe rolls, into cooling hydrosphere 4, normal water flowing can be real
Now to the refrigerating function of roll 2.
It is fixed in order to guarantee, locating piece further can be set in 1 two sides corresponding position of roll stand, prevent cooling hydrosphere
4 axial floats.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
