Abstract
The utility model relates to a mill roll, in particular to a mill roll with cooling liquid cooled in the mill roll. An internal cooling mill roll comprises a mill roll shaft and a roll sleeve wrapped outside the mill roll shaft, wherein a spiral groove is distributed on the mill roll shaft circumferentially; one end of the spiral groove is communicated with an input hole of the cooling liquid and the other end of the spiral groove is communicated with an output hole of the cooling liquid; the input hole is positioned at one end of the mill roll shaft; and the output hole is positioned at the other end of the mill roll shaft. The internal cooling mill roll has a simple structure, is low in cost and is easy to manufacture. The internal cooling mill roll is circularly cooled by an annular groove, is cooled uniformly, has a good cooling effect and is convenient to maintain.
Description
Technical field
The utility model relates to a kind of roll, and especially a kind of cooling fluid is at the inner colded roll of roll.
Background technology
At present, cooling and outer cooling in the method for existing cooling roll has.Wherein outer cooling method generally is around roll, to spray cooling fluid, and this mode is not suitable for requirement production environment drying, free of contamination situation.Internal cooling method generally is on roll mandrel, to have through hole, and feeds cooling fluid, reaches the purpose of cooling through liquid circulation.Because through hole has certain distance apart from the roll mandrel circumference, so only can reduce near the temperature the through hole, cooling effect is limited, and roll mandrel can be because uneven in temperature and be out of shape.
The utility model content
The technical problem that the utility model will solve is: based on the problems referred to above, a kind of interior cooling roll even, good cooling results that cools off is provided.
The utility model solves the technical scheme that its technical problem adopted: cooling roll in a kind of; Comprise the roller shell that roll mandrel is outer with being coated on roll mandrel; Described roll mandrel upper edge circle distribution has helicla flute, and spiral fluted one end communicates with the cooling fluid input hole, and the other end communicates with the cooling fluid delivery outlet; Input hole is positioned at an end of roll mandrel, and delivery outlet is positioned at the other end of roll mandrel.
Described roll mandrel two ends are connected with second swivel joint of drawing cooling fluid to first swivel joint of input hole introducing cooling fluid with to delivery outlet respectively.
The beneficial effect of the utility model is: the utility model is simple in structure, easy to manufacture, cost is low; Through cannelure circulation cooling, cooling evenly, good cooling results, be convenient to maintenance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is along the expanded view of D among Fig. 1.
Among the figure: 1. roll mandrel, 2. axle sleeve, 3. helicla flute, 4. input hole, 5. delivery outlet.
The specific embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of interior circulation cooling roll shown in Fig. 1 or 2; Comprise roll mandrel 1 and the roller shell 2 that is coated on outside the roll mandrel 1; Roll mandrel 1 upper edge circle distribution has helicla flute 3, and an end of helicla flute 3 communicates with cooling fluid input hole 4, and the other end communicates with cooling fluid delivery outlet 5; Input hole 4 is positioned at an end of roll mandrel 1, and delivery outlet 5 is positioned at the other end of roll mandrel 1.
Roll mandrel 1 two ends are connected with second swivel joint of drawing cooling fluid to first swivel joint of input hole 4 introducing cooling fluids with to delivery outlet 5 respectively.
During practical implementation, cooling fluid is incorporated into input hole 4 by first swivel joint, flows along helicla flute 3 then, and cooling roll mandrel 1 is drawn through delivery outlet 5 by second swivel joint at last, and so roll mandrel 1 is cooled off in circulation.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
