Abstract
The invention relates to a backup roller for an air-cooled quenching furnace. The backup roller comprises a main roller body, wherein the two ends of the main roller body are respectively welded with transition connecting rollers, the outer ends of the transition connecting rollers are welded with shaft ends, thermal insulating material filling layers are arranged in the transition connecting rollers, and the thermal insulating material filling layers are sealed by baffles. The backup roller is characterized in that the main roller body adopts a hollow structure, ventilation holes are formed in the shaft ends, and a rotating connector used for connecting high-pressure air is mounted at the outer end of the ventilation hole in one shaft end; transition air channels are arranged in the thermal insulating material filling layers and the baffles, the transition air channels are communicated with the inner ends of the ventilation holes in the shaft ends at the corresponding ends, and a rotating connector used for connecting high-pressure air is mounted at the outer end of a ventilation hole passage in one shaft end. The support roller is timely cooled in an air cooling manner. The damage of the support roller is prevented from occurring for being under a high temperature work condition for long time, and the support roller is effectively protected. Besides, the structural strength of the support roller can also be improved, the service life of the support roller is improved, and equipment maintenance cost is reduced.

Background technology
Quenching furnance is widely used a kind of laser heating equipment for Heating Processing in industrial heat treatment industry.Quenching furnance mainly comprises body of heater, heating arrangements (electrically heated or flame heating), running gear (dynamic beam motion parts, fire door lifting part, pan feeding/output section machinery etc.), control part grade.The supporting roll being wherein positioned at quenching furnance needs the test standing high temperature.Traditional protection suffered by quenching furnance supporting roll is inadequate, and supporting roll in use for some time, can damage owing to being in for a long time under worst hot case, cause quenching furnance device fails, often need to be serviced.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of air-cooled quenching furnance supporting roll is provided, its structure design is simple, compact, reasonable, adopts air cooling way to be cooled in time by supporting roll, avoid supporting roll to be in for a long time under worst hot case to damage, available protecting supporting roll; But also the structural strength of supporting roll can be improved, improve the work-ing life of supporting roll, reduce maintenance of equipment maintenance cost.
According to technical scheme provided by the invention: air-cooled quenching furnance supporting roll, comprise main roll body, described main roll body two ends are welding transition connection roll respectively, described transition connection roll outer end welding spindle nose, be provided with lagging material packing layer in transition connection roll, described lagging material packing layer is encapsulated by baffle plate; It is characterized in that: described main roll body is hollow structure, is provided with ventilation hole in described spindle nose, the ventilation hole outer end on one of them spindle nose is provided with the swivel joint for connecting high-pressure air; Be provided with transition air channel in described lagging material packing layer and baffle plate, described transition air channel is connected with the ventilation hole the inner on corresponding end spindle nose, and the ventilating hole channel outer end on one of them spindle nose is provided with the swivel joint for connecting high-pressure air.
As a further improvement on the present invention, spiral plate is provided with in described main roll body, the neighboring of described spiral plate is along being welded and fixed with main roll body inwall, and form volution air channel between described spiral plate and main roll body, two ends, described volution air channel are communicated with the transition air channel at two ends respectively.
As a further improvement on the present invention, described transition connection roll is cone, and the stub end of transition connection roll connects main roll body, the little head end coupling shaft head of transition connection roll.
compared with the prior art the present invention, has the following advantages:
Structure design of the present invention is simple, compact, reasonable, adopts air cooling way to be cooled in time by supporting roll, avoids supporting roll to be in for a long time under worst hot case and damage, available protecting supporting roll; But also the structural strength of supporting roll can be improved, improve the work-ing life of supporting roll, reduce maintenance of equipment maintenance cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, the air-cooled quenching furnance supporting roll in embodiment is primarily of compositions such as main roll body 1, transition connection roll 2, lagging material packing layer 3, spindle nose 4, swivel joint 5, spiral plate 6 and baffle plates 7.
As shown in Figure 1; described main roll body 1 two ends are welding transition connection roll 2 respectively; described transition connection roll 2 outer end welding spindle nose 4; lagging material packing layer 3 is provided with in transition connection roll 2; described lagging material packing layer 3 is encapsulated by baffle plate 7; lagging material packing layer 3 is used for protecting supporting roll, avoids its temperature rise too fast.
As shown in Figure 1, described main roll body 1 is hollow structure, is provided with ventilation hole 4a in described spindle nose 4, and the ventilation hole 4a outer end on one of them spindle nose 4 is provided with the swivel joint 5 for connecting high-pressure air; Be provided with transition air channel 3a in described lagging material packing layer 3 and baffle plate 7, described transition air channel 3a is connected with the ventilation hole 4a the inner on corresponding end spindle nose 4, and the outer end, ventilation hole 4a road on one of them spindle nose 4 is provided with the swivel joint 5 for connecting high-pressure air.
As shown in Figure 1, spiral plate 6 is provided with in described main roll body 1, the neighboring of described spiral plate 6 is along being welded and fixed with main roll body 1 inwall, and form volution air channel between described spiral plate 6 and main roll body 1, two ends, described volution air channel are communicated with the transition air channel 3a at two ends respectively.
As shown in Figure 1, in the embodiment of the present invention, described transition connection roll 2 is cone, and the stub end of transition connection roll 2 connects main roll body 1, the little head end coupling shaft head 4 of transition connection roll 2.
During work, by swivel joint 5 to supporting roll inner ventilation, heat can be taken away rapidly, avoid supporting roll temperature rise too high, protection supporting roll.Spiral plate 6 simultaneously can improve the structural strength of main roll body 1.
