Description
Technical Field
The utility model relates to the technical field of rollers, in particular to an internal cooling roller.
Background
At present, the existing method for cooling the roller has internal cooling and external cooling. The external cooling method is generally to spray cooling liquid around the roller, which is not suitable for the condition that the production environment is required to be dry and pollution-free. The internal cooling method is generally that a through hole is arranged on a roll shaft, cooling liquid is introduced into the through hole, and the purpose of cooling is achieved through circulation of the cooling liquid. At present, all offer the helicla flute around the shaft usually, because be one section very long distance through the helicla flute between inlet and the liquid outlet, the head difference in temperature of inside coolant liquid is great, and the coolant liquid of liquid outlet rises obviously through round helicla flute after temperature, and is not obvious to the cooling effect near the liquid outlet, and the roll axle can warp because the cold and hot is uneven.
For this purpose, we have designed an internally cooled roll.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: overcomes the defects in the prior art and provides an internally cooled roller.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides an internal cooling roll, includes the roll body, roll body both ends symmetry is provided with the roll neck, the outside symmetry of roll neck is provided with the roller, the one end of roll body is provided with first cavity, the other end of roll body is provided with the second cavity, the interior circumference of roll body evenly is provided with the cooling tube, the cooling tube distributes along roll body axial, the one end of cooling tube with first cavity intercommunication, the other end of cooling tube with second cavity intercommunication, keep away from the roller middle part of first cavity one side and seted up the inlet, the roller middle part of inlet opposite side is provided with the liquid outlet, the inlet with first cavity intercommunication, the liquid outlet with second cavity intercommunication.
Further, fixed grooves are uniformly formed in the circumferential direction of the surface of the roller shaft.
Further, the volume of the first chamber is greater than the volume of the second chamber.
Further, the liquid inlet is communicated with the middle part of the first cavity.
Further, the liquid outlet is communicated with the middle part of the second cavity.
Furthermore, one end of the cooling pipe is communicated with the peripheral wall of the first chamber, and the other end of the cooling pipe is communicated with the peripheral wall of the second chamber.
The utility model has the beneficial effects that: the roller cooling device is simple in structure, reasonable in design and simple and convenient to operate, a plurality of axially distributed cooling pipes are arranged in the roller body to replace a spiral cooling path, so that the path through which cooling liquid passes is shorter, the temperature of each part of the cooling liquid is relatively uniform, the cooling effect is obvious and efficient, the large temperature difference between the cooling liquid near the liquid inlet and the liquid outlet due to a long cooling circulation path is avoided, the cooling effect near the liquid outlet is not obvious, and the roller is deformed due to uneven cooling and heating.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a perspective view of the present invention;
FIG. 2 is a transverse cross-sectional view of the present invention;
fig. 3 is a vertical cross-sectional view of the present invention.
In the figure: 1. the roller comprises a roller body, 2 roller necks, 3 roller shafts, 4 cooling pipes, 5 first cavities, 6 second cavities, 7 liquid inlets, 8 liquid outlets and 9 fixing grooves.
Detailed Description
The utility model will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, interior cooling roll, including shaft 1, 1 both ends symmetry of shaft is provided with roll neck 2, the outside symmetry of roll neck 2 is provided with roller 3, the one end of shaft 1 is provided with first cavity 5, the other end of shaft 1 is provided with second cavity 6, the interior circumferencial cooling tube 4 that evenly is provided with of shaft 1, cooling tube 4 distributes along 1 axial of shaft, the one end and the first cavity 5 intercommunication of cooling tube 4, the other end and the second cavity 6 intercommunication of cooling tube 4, keep away from roller 3 middle part on one side of first cavity 5 and seted up inlet 7, the roller 3 middle part of inlet 7 opposite side is provided with liquid outlet 8, inlet 7 and first cavity 5 intercommunication, liquid outlet 8 and the 6 intercommunication of second cavity. The end part of the roll shaft 3 with the liquid inlet 7 and the liquid outlet 8 is connected with a rotary joint which injects cooling liquid into the liquid inlet 7 and leads out the cooling liquid to the liquid outlet 8.
Fixed grooves 9 are uniformly formed in the circumferential direction of the surface of the roller shaft 3 and used for being clamped with an external connecting device, and therefore the whole roller is fixed with external equipment.
The volume of the first chamber 5 is larger than that of the second chamber 6, the first chamber 5 can store more cooling liquid, and the volume of the second chamber 6 is small so as to quickly discharge the cooling liquid which is heated after being gathered, so that the local temperature is prevented from rising.
The liquid inlet 7 is communicated with the middle part of the first cavity 5, and the liquid outlet 8 is communicated with the middle part of the second cavity 6.
One end of the cooling pipe 4 penetrates the peripheral wall of the first chamber 5, and the other end of the cooling pipe 4 penetrates the peripheral wall of the second chamber 6.
During operation, the coolant liquid pours into inlet 7 through the adapter, then flows along cooling tube 4, and cooling roller body 1 is discharged through rotary joint by liquid outlet 8 at last, so circulation come cooling roller's roller body 1.
While particular embodiments of the present invention have been described in the foregoing specification, the present invention is not limited to the specific embodiments, and modifications and variations of the foregoing detailed description can be made by those skilled in the art without departing from the spirit and scope of the utility model.
