Content based on above-described embodiment, Fig. 2 are according to a kind of structure diagram of water cooled rolls of the utility model, are such as schemed
Shown in 2, outer inlet channel 5 is opened in the axle center of the first support shaft 9, and outer water outlet 6 is opened in the axle center of the second support shaft 10, left and right
The center of roller positioning plate 3 and outer roller positioning plate 4 is provided with through hole in both sides, roller in the shaft end and left side of the first support shaft 9
The through hole of cylinder positioning plate 3 and outer roller positioning plate 4 is connected with integration is merged, roller in the shaft end and right side of the second support shaft 10
The through hole of positioning plate 3 and outer roller positioning plate 4 is connected with integration is merged.
Specifically, in order to preferably be cooled down using water cooled rolls, it is necessary in both sides installation support shaft, turn easy to water cooled rolls
It is dynamic.Outer inlet channel 5 is processed in the axle center of the first support shaft 9, outer water outlet 6, processing side are processed in the axle center of the second support shaft 10
Formula it is same can be machine drilling, but not limited to this.By roller positioning plate 3 in the shaft end and left side of the first support shaft 9 and
The through hole of outer barrel positioning plate 4 is with integration connection is merged, by roller positioning plate 3 in the shaft end and right side of the second support shaft 10 and outside
The through hole of cylinder positioning plate 4 is passed through with integration connection is merged since the radial direction of the roller positioning plate 3 along the left and right sides offers respectively
Logical interior inlet channel 7 and interior water outlet 8, therefore interior inlet channel 7, through the first support shaft 9, interior water outlet 8 is through second
Axis 10 is supportted, ensures that outer inlet channel 5 is connected with interior inlet channel 7, outer water outlet 6 is connected with interior water outlet 8, is existed so as to fulfill cooling water
The circulation of working region.
A kind of water cooled rolls provided in this embodiment, by installing support shaft in the both sides of water cooled rolls, facilitates water cooled rolls to rotate,
Increase and the area of heat exchange with outside, while the working region between exterior water channel and inside and outside roller is connected, ensureing water cooling
Contact area it is maximized on the basis of reduce unnecessary water space inside water cooled rolls, so as to improve the cooling effect of water cooled rolls
Fruit.
The shaft end of content based on the various embodiments described above, the first support shaft and second support shaft is step type, described
The through-hole aperture of interior roller positioning plate is less than the through-hole aperture of the outer roller positioning plate.For the ease of the first support shaft and described
The axially position of second support shaft, step type, the section of end are designed as by the shaft end of the first support shaft and the second support shaft
Area diminishes, the position of area of section change for interior roller positioning plate and outer roller positioning plate interface, and by interior roller
The through-hole aperture of positioning plate is designed to the through-hole aperture less than the outer roller positioning plate, easy to the first support shaft with step type
Coordinate with the second support shaft, ensure the accuracy of axially position.
Content based on the various embodiments described above, as shown in Fig. 2, first support shaft 9 and second support shaft 10
Shaft end is respectively equipped with plug 11.Plug, also referred to as pipe cap, headkerchief, tube cover or silently, for unwanted mouth in pipeline is blocked up
Get up, play sealing process, can directly be spun on pipe to upper, pipe can also be welded on to upper, the present embodiment selects welding design.For
Facilitate mechanical processing, the outer water outlet 6 in 5 and second support shaft 10 of outer inlet channel in the first support shaft 9 is processed as passing through
Logical water channel, needs outer inlet channel 5 and interior inlet channel 6 plug 11 is respectively welded by one end of proximal ends and is blocked at this time,
Prevent cooling water from entering the inner space of interior roller 1, so that cooling effect can be reduced.
Content based on the various embodiments described above, the bore of the outer inlet channel are more than the bore of the outer water outlet.Will be cold
But water enters interior inlet channel by outer inlet channel, then enters the closed area between inside and outside roller by interior inlet channel, because of inlet diameter
More than outlet diameter, cooling water can effectively fill up the closed area between inside and outside roller, since outer roller is contacted with high temperature foil,
Outer roller temperature is higher, and cooling water flows through the inner surface of outer roller, sucks heat, cold under the action of inlet pressure and flow
But water more easily enters outer water outlet by interior water outlet and discharges, and improves the cycle efficieny of cooling water, is mixed so as to improve water cooling
Cooling effect.
Content based on the various embodiments described above, Fig. 3 is the profile in K-K sections in Fig. 2, with reference to shown in Fig. 2 and Fig. 3, institute
It is multiple to state interior inlet channel 5 and interior water outlet 6.The radial direction of roller positioning plate 3 offers the interior water inlet of multiple perforations in left side
Road 5, the radial direction of roller positioning plate 3 offers the interior water outlet 6 of multiple perforations, the so cooling water for inflow in right side,
The circumferential area surrounded between working region, that is, interior roller 1 and outer roller 2 can be flowed rapidly into, while can be quick
The water that cold and hot exchange has been carried out in working region is discharged to out outlet, further increases the cooling effect of whole water cooled rolls
Fruit.
The mode of content based on the various embodiments described above, the sealing and the integration connection is air-tightness welding.
Air-tightness welding is exactly to ensure do not have penetrability defect after welding, and the gastight meaning, does not require face of weld matter generally
The welding of amount carries out kerosene leakage experiment after completing, then need to carry out air-tight test or dye penetrant inspection inspection if any particular/special requirement
Look into.In order to ensure the leakproofness of whole device, the mode that all sealings and integration connect is required for welding using air-tightness,
Ensure that cooling water is flowed according to the channel sequence of outer inlet channel, interior inlet channel, working region, interior water outlet and outer water outlet, no
Cooling water leakage scene can occur, so as to influence cooling effect.
A kind of water cooled rolls provided by the utility model, by the internal water that perforation is radially opened up in interior roller positioning plate
Road, the cooling water working region between exterior water channel and inside and outside roller is directly connected, and is ensureing the maximum of water cooling contact area
Unnecessary water space inside water cooled rolls is reduced on the basis of change, so as to accelerate the circulation after cooling water heat exchange, is improved
The cooling-down effect of water cooled rolls.
Finally, the device in the utility model is only preferable embodiment, is not intended to limit the guarantor of the utility model
Protect scope.Where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on, should all include
Within the scope of protection of the utility model.
