Detailed description of the invention
1～2 detailed description of the invention of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of mill or rolling mill roller, including the roller shaft core 2 being set-located, roller overcoat 1,
The inner surface of roller overcoat 1 offers along one end spiral surrounding of roller overcoat 1 to the heat exchange groove 6 of the other end, roller overcoat 1
This heat exchange groove 6 of inner surface cooperatively forms screw type medium runner 5 with the outer surface of roller shaft core 2.Roller overcoat 1 is chill
Cast iron quality or alloy chilled cast iron quality, top layer is chill, and hardness is high, and wearability is good, can bear in mixing process
The frictional force of sizing material and corrosiveness.Roller shaft core 2 is 45 steel matter or 40Cr material or 40MnB material, and shaft core intensity is big,
Good rigidly, it is ensured that will not rupture when roller bears bigger horizontal pressure, consults national standard and understands, cast iron, alloy chilled
The elastic modelling quantity of cast iron is 110～160GPa, and 45 steel, the elastic modelling quantity of 40Cr or 40MnB are 200～210GPa, therefore make
Do shaft core with 45 steel, 40Cr or 40MnB and can be substantially reduced the roller bending deformation quantity when stress, it is ensured that machining accuracy,
Owing to roller shaft core 2 and roller overcoat 1 use combination type to design, the advantage having concentrated bi-material, ensureing that roller surface is hard
While degree and wearability, improve rigidity and the intensity of roller.
It is provided with through hole at the axle center of roller shaft core 2 as sprue 10, in through hole, is provided with feed tube 7.Roller shaft core 2 close
The side of feed tube 7 liquid outlet is provided with the first radial flow path and is provided with as feed liquor runner 3, the side away from feed tube 7 liquid outlet
Second radial flow path is respectively communicated with screw type medium runner 5 and main flow as drain pipe road 4, input duct 3 and drain pipe road 4
Road 10, input duct 3, drain pipe road 4 are respectively four, respectively along the radially uniform distribution of roller, it is ensured that roller is rotating through
Diverse location in journey can have medium to flow in or out screw type medium runner 5.One end of roller shaft core 2 and swivel joint 8
Connecting, for feed liquor and discharge opeing, the other end of roller shaft core 2 sealing-plug seals, and prevents medium from revealing.Heat exchange groove 6 is square
Tee section heat exchange groove.The outlet side of feed tube 7 is provided with the sealing member 9 being set in feed tube 7 outer surface, and this sealing member 9 is used for
Sealing between feed tube 7 outer surface and through-hole inner surface.
Roller shaft core 2 and roller overcoat 1 interference fit, assembled by hot charging mode, and roller overcoat 1 oil bath is sleeved on after swelling
In roller shaft core 2, naturally cool to ordinary temperature.The outer surface of roller shaft core 2 scribbles fluid sealant.
During work, as a example by cooling, cooling medium constantly flows into from the water inlet pipe of swivel joint, directly arrives (figure on the right side of roller
Right side in 1), the relatively low cooling medium of temperature enters screw type medium runner 5 by input duct 3, and is situated between along screw type
Mass flow road 5 is from right side flow to left side liquid outlet, and in flow process, cooling medium is near with sizing material distance, constantly carries out heat friendship
Change, thus reduce the temperature of sizing material, when flow to left side liquid outlet time, cooling medium through drain pipe road 4 from swivel joint
Liquid outlet flows out, thus completes whole heat transfer process.
This roller adds man-hour, and roller overcoat 1 is obtained blank by casting method, first carries out roughing, then inner surface need with
The part that roller shaft core 2 cooperates carries out polish, at the inner surface heat exchange groove 6 of one screw type of Boring machine processing, roller
Shaft core 2 also takes casting method to obtain blank, first blank is carried out preprocessing, including correction, section and drill centers,
Then roughing centre bore and roller shaft core 2 outer surface, respectively process four holes at roller shaft core 2 two ends, as
Liquid inlet and outlet pipeline 4, pair roller barrel shaft core 2 is modulated processing afterwards, is assembled together with roller shaft core 2 by roller overcoat 1,
The course of processing is simple, and difficulty of processing is little.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this skill
Change that the technical staff in art field is made in essential scope of the present utility model, retrofit, add or replace, also should belong to
Protection domain of the present utility model.
