The summary of the invention the purpose of this utility model is to provide the hot pressing smooth roll of a kind of thermal conductivity height, a kind of calender that energy loss is little.The utility model mainly includes roller, fore side spindle nose, transmission side spindle nose and swivel joint.Wherein, roller is a thick cyclinder, and being provided with the through hole that some and openings parallel with the roller axis are positioned at the roller two ends in barrel is thermal hole, and every thermal hole both ends are equipped with the heat conduction that is connected with the roller inwall and prop up the hole.One end of roller is provided with the transmission side spindle nose, and the one side is provided with the minor axis that can link to each other with motor and reducing gear thereof, but this minor axis middle part peripheral hardware rolling bearing, and this rolling bearing is located on the bearing block to support an end of roller.The other end of this solid transmission side spindle nose is provided with the flange that roller one end (comprising thermal hole) can be covered, and the through hole on it is corresponding with the screw of roller end, by securing member the transmission side spindle nose is linked to each other with roller.Be provided with the boss platform that can place in the roller at above-mentioned transmission side spindle nose flange one middle side part, be provided with radial direction through hole in this boss platform, the both ends open of this radial direction through hole is located at respectively on the periphery of boss, and each to prop up the hole corresponding with a heat conduction.The roller other end is provided with the fore side spindle nose, and its profile is the same substantially with the transmission side spindle nose, and a minor axis is promptly arranged, but this minor axis middle part peripheral hardware rolling bearing, and this rolling bearing is located on the bearing block to support the other end of roller.The other end of this fore side spindle nose is provided with the flange that roller one end (comprising thermal hole) can be covered, and the through hole on it is corresponding with the screw of roller end, by securing member the fore side spindle nose is linked to each other with roller.Be provided with the boss platform that can place in the roller at aforesaid operations side shaft head flange one middle side part, this boss platform is established radial direction through hole in half, one end opening of this radial direction through hole is located on the periphery of boss, and with half heat conduction to prop up the hole corresponding, the other end opening of this radial direction through hole is located in boss middle part and the cavity that inner sleeve is connected; This boss platform is established oblique through hole in second half, and an end opening of this oblique through hole is located on the periphery of boss, and to prop up the hole corresponding with second half heat conduction, and the other end opening of this oblique through hole is located in boss middle part and the cavity that outer tube is connected.Establish the cavity that runs through the spindle nose two ends in the aforesaid operations side shaft head, the end that this cavity is positioned at minor axis links to each other with swivel joint by flange, and the outlet of this swivel joint is connected with outer tube, and the inlet tube of this swivel joint is connected with inner sleeve.The other end of above-mentioned internal and external casing is positioned at the cavity of fore side spindle nose boss platform, and its end top is provided with and stops thermal medium to enter the interior dividing plate of cylinder.The inner peripheral hardware central through hole cover of above-mentioned inner sleeve sealing ring thereon, the outer peripheral face of sealing ring is stuck on the cavity wall at boss platform middle part, the cavity at boss platform middle part is separated into two chambeies, and an one chamber is connected with inner sleeve, and another chamber is connected with outer tube.
The course of work of the present utility model is as follows substantially: thermal medium (oil or steam) enters inner sleeve from the swivel joint import, come out to enter in the cavity of fore side spindle nose boss platform from the inner sleeve other end again, be dispersed to again from this cavity in the radial direction through hole of boss platform, again by entering in the heat pipe with the corresponding heat conduction arm of radial direction through hole.Heat-conducting medium from the fore side spindle nose to the process of transmission side spindle nose operation, conduct heat on the roller wall, so can realize that roller is to the page hot calendered.When cooling back thermal medium runs to transmission side spindle nose one end, enter the radial direction through hole of transmission side spindle nose boss platform by the heat conduction arm, the reflux medium that comes out from this radial direction through hole other end enters again in the heat pipe in second half roller wall, when it runs to fore side spindle nose one end, enter in another cavity of fore side spindle nose boss platform via heat conduction arm and the oblique through hole of boss platform corresponding with it, enter the swivel joint outer tube by this cavity again, discharge from the outlet of swivel joint then.
The utility model compared with prior art has following advantage:
1, good heat conduction effect, energy loss is little, and operating cost is low.
2, hot pressing smooth roll used vapour or conduction oil two media carry out heat conduction, are convenient to the utilization of resources and process choice.
3, simple in structure, dependable performance.
