Detailed description of the invention
Fig. 1 ~ 7 are most preferred embodiments of the present utility model, are described further below in conjunction with 1 ~ 7 pair of this utility model of accompanying drawing.
A kind of crown controlled roll, the cylinder 3 outside mandrel 1 it is located at including mandrel 1 and turning set, mandrel 1 is interval with multiple hydrostatic support piston 2, mandrel 1 is provided with outage 4, the side of mandrel 1 is provided with storage tank 8, offer the fuel feed hole 10 connected with hydrostatic support piston 2 and the transitional pore 13 connected with mandrel 1 end face in storage tank 8, in storage tank 8, be provided with the oil pipe 12 connected with fuel feed hole 10 by transitional pore 13.Mandrel 1 side of this crown controlled roll is provided with storage tank 8, and it is respectively equipped with fuel feed hole 10 and transitional pore 13 in storage tank 8, oil pipe 12 is arranged in storage tank 8 and by the fuel feed hole 10 in storage tank 8 and transitional pore 13, hydraulic oil flows to hydrostatic support piston 2, axial through hole need not be offered at the middle part of mandrel 1 man-hour adding, greatly reduce difficulty of processing, and it is easy for installation, seal request is low, and when maintenance, have only to change oil pipe 12 or the sealing member of damage, greatly reduce the difficulty of maintenance.
Concrete: as shown in Figure 1: cylinder 3 is cylinder, the internal diameter of cylinder 3 is more than the external diameter of mandrel 1, and cylinder 3 is set in the outside of mandrel 1, and cylinder 3 is coaxially connected with mandrel 1, and the cylindrical interval of the inwall of cylinder 3 and mandrel 1 is arranged.The outer wall of cylinder 3 is coated with composite, it is also possible to coated composites, thus paper surface is carried out press polish.
Mandrel 1 end is sequentially provided with cylinder installation portion 7 and crown controlled roll installation portion 6 from inside to outside, and the external diameter of cylinder installation portion 7 is less than the external diameter of mandrel 1, more than the external diameter of crown controlled roll installation portion 6.Cylinder installation portion 7 is arranged with cylinder bearing 5, the two ends of cylinder 3 be respectively sleeved on cylinder bearing 5 outer wall and with cylinder bearing 5 compact siro spinning technology.
Being interval with 12 hydrostatic support pistons 2 on mandrel 1, hydrostatic support piston 2 is arranged on mandrel 1.When paper web is carried out press polish, bending under the effect of the pressure of cylinder 3, hydraulic oil can form hydrostatic support oil film between hydrostatic support piston 2 and cylinder 3 inwall, cylinder 3 is played a supporting role, thus avoiding cylinder 3 to bend, hydrostatic support oil film greatly reduces the friction between hydrostatic support piston 2 and cylinder 3 inwall, improves the service life of cylinder 3, and the calendaring effect is good.
As shown in Figure 2: storage tank 8 is symmetricly set on the both sides of mandrel 1, storage tank 8 makes oil pipe 12 can be respectively distributed to mandrel 1 both sides, increase the distribution space of oil pipe 12, and the mandrel 1 intensity at vertical direction will not be weakened, mandrel 1 can play at vertical direction and reliably support, it is ensured that web calendered effect.
The top of mandrel 1 is provided with the installing hole 14 for installing hydrostatic support piston 2, installing hole 14 has 12 uniformly at intervals, installing hole 14 is columned blind hole, installing hole 14 is mainly used in installing hydrostatic support piston 2, the top loop of installing hole 14 is provided with the seal groove of annular around inwall, and hydrostatic support piston 2 and installing hole 14 are sealed by sealing ring.
Fuel feed hole 10 is " L " shape, and one end of fuel feed hole 10 connects with the bottom of installing hole 14, and the other end is arranged in storage tank 8.One end that fuel feed hole 10 is arranged in storage tank 8 is provided with screw thread, and it is oil inlet end that fuel feed hole 10 is positioned at one end of storage tank 8, and fuel feed hole 10 oil inlet end is provided with oil connection 9 by screw thread, is conveniently connected with oil pipe 12.
As shown in Figure 3: due to when bending, installing hole 14 more than the radius of curvature at middle part, therefore can be divided into different nips by the radius of curvature at cylinder 3 two ends, thus the different parts of cylinder 3 is supported, support effect is good, does not have the problem that transition supports.First installing hole 14 being positioned at mandrel about 1 two ends forms two independent nips respectively；Second and third installing hole 14 at mandrel 1 both ends forms two independent nips；Six installing holes 14 being positioned at middle part form two nips, three installing holes 14 of each nip.
Connected by skewed oil guiding hole 11 between the installing hole 14 of identical nip.The bottom side connection of the installing hole 14 that the two ends of oil guiding hole 11 are adjacent with same nip respectively.Same nip has and only one of which installing hole 14 connects with fuel feed hole 10, decreases the quantity of fuel feed hole 10, thus reducing difficulty of processing, and decreasing the quantity of oil pipe 12, decreasing the space of oil pipe 12 duty.
Outage 4 is "T"-shaped, the horizontal part of outage 4 and mandrel 1 are coaxially disposed, and the termination of horizontal part is arranged on crown controlled roll installation portion 6 termination, the two ends of the vertical portion of outage 4 are arranged at the outer wall of mandrel 1, can adapt to crown controlled roll be arranged on hot-rolling top and be arranged on two kinds, hot-rolling bottom situation, improve the versatility of mandrel 1.Outage 4 has two, is separately positioned on the two ends of mandrel 1.
As shown in Fig. 4 ~ 5: owing to the installing hole 14 on mandrel 1 is always divided into six nips, therefore connect each nip fuel feed hole 10 and be divided into two groups, the oil inlet end of two groups of fuel feed holes 10 is separately positioned in two storage tanks 8, so when arranging oil pipe 12, three oil pipes 12 it are provided with in each storage tank 8, space that a storage tank 8 causes storage tank 8 is not enough to avoid oil pipe 12 to be positioned at, the problem even squeezing into oil pipe.
As shown in Fig. 6 ~ 7: transitional pore 13 is also " L " shape elongated hole, the vertical portion of transitional pore 13 is parallel with the axis of mandrel 1, horizontal part overlaps with the radius of mandrel 1, and one end of transitional pore 13 is arranged on the termination of crown controlled roll installation portion 6, and the other end is arranged in storage tank 8.The quantity of transitional pore 13 is equal with the quantity of nip, has six, and six transitional pores 13 are arranged at same one end of mandrel 1.It is oil outlet end that transitional pore 13 is positioned at one end of storage tank 8, and oil outlet end is provided with screw thread, is used for installing oil connection 9, conveniently connects with oil pipe 12.
One end that oil pipe 12 one end is positioned at storage tank 8 with transitional pore 13 connects, one end that the other end is positioned at storage tank 8 with fuel feed hole 10 connects, when maintenance, have only to change the oil pipe 12 damaged or sealing member, easy to maintenance, and oil pipe 12 is connected with fuel feed hole 10 and transitional pore 13 respectively by oil connection 9, easy accessibility.
This crown control roll nip quantity can select according to the length of mandrel 1, and the quantity of the installing hole 14 of each nip is adjusted also according to the degree of crook of cylinder 3.
The above, it it is only preferred embodiment of the present utility model, being not the restriction that this utility model is made other form, any those skilled in the art are changed or are modified as the Equivalent embodiments of equivalent variations possibly also with the technology contents of the disclosure above.But every without departing from technical solutions of the utility model content, any simple modification, equivalent variations and remodeling above example made according to technical spirit of the present utility model, still fall within the protection domain of technical solutions of the utility model.
