Description
Technical field
Vulcanizer technical field is the utility model is related to, specially a kind of sealing mechanism of novel central mechanism of vulcanizing machine.
Background technology
Vulcanizer is applied to the vulcanization of various products of rubber and plastic, compacting；After preheating, feeding needed for rubber vulcanization process
The functions such as automatic-discharging gas, pressurize vulcanization, timing and alarming, automatic die sinking, product depanning are in one.Typically controlled using PLC, tool
Have and automatically and manually operate（It is customized by user's actual need）, required technological process, remote operation and system pipes can be recorded
Reason.
The sealing ring of vulcanizer center fixture is to complete to prevent with phenyl tetrafluoride pad centre device gland in the prior art
Leak-stopping steam, phenyl tetrafluoride pad high temperature resistance is poor, easy to aging, and a phenyl tetrafluoride pad need to just be changed by generally requiring 2 to 3 months；Due to sulphur
The start of change machine needs to preheat for a long time, stops vulcanizer work for manufacturer and abstains from the most.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of novel central mechanism of vulcanizing machine it is close
Sealing mechanism, including gland, the gland is arranged on sealing jacking portion by sealing nut, and the sealing nut passes through floating cap
It is fixed on gland, asbestos board is provided between the sealing support and gland, the sealing support hollow layer is provided with sealing ring, and described
Sealing ring is connected with one group in telescopic column root and tiltedly organizes sealing ring, and expansion bend is provided between the sealing ring and telescopic column,
The expansion bend is provided with laminate, is provided with spring between the laminate, and the gland, asbestos board, sealing ring and tiltedly organizes sealing ring
It is socketed on telescopic column.
As a kind of preferable technical scheme of the utility model, the expansion bend is fixed on telescopic column by fastener,
And can be radially movable.
As a kind of preferable technical scheme of the utility model, the sealing ring uses rubber seal, and using Y types
Rubber seal.
As a kind of preferable technical scheme of the utility model, the gland, sealing support use Q-235 steel materials.
Compared with prior art, the beneficial effects of the utility model are：Floating sealing is mainly by seal receptacle, floating
Set, sealing ring, asbestos board and a few part compositions of gland, seal receptacle are to be welded to connect with cylinder body.Sealing ring still uses Y type rubber
Sealing ring, it is arranged on using two sealing rings backwards to opposed installation form outside floating bushing.Floating bushing can edge in seal receptacle
Radially fluctuate, the top of sealing ring is connected and fixed by asbestos board and gland by screw.The axial direction of center pull rod is close
Envelope is achieved by two sealing rings, while the floating bushing equipped with sealing ring can be carried out with the circular runout of center pull rod
Fluctuate, reduce the stress of sealing ring, extend the service life of sealing ring, installed in the root of center pull rod
One group is tiltedly organized sealing ring, makes tiltedly be blocked at group sealing ring with the mixture that telescopic column motion is brought, due to oblique group
Sealing ring is mounted in telescopic column root, and the gap for having 2~3 mm is held in the palm in expansion bend and the sealing of its outer ring, therefore close
Seal can carry out fluctuating for small range with center pull rod in radial direction, thus substantially reduce sealing ring in footpath
The extruding force for the telescopic column being subject to direction, the stress of sealing ring is improved, make sealing ring by axially being rubbed originally
Making a concerted effort for power and radial compression power is wiped, is changed into only by the frictional force of axial direction.The change of stress, make the mill of rubber seal
Damage situation has obtained preferable improvement, extends service life.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of sealer of novel central mechanism of vulcanizing machine
Structure, including gland 2, the gland 2 are arranged on sealing support 4 top by sealing nut 11, and the sealing nut 11 pass through it is floating
Dynamic cap 3 is fixed on gland 2, and asbestos board 5 is provided between the sealing support 4 and gland 2, and sealing support 4 hollow layer is provided with close
Seal 10, and the sealing ring 10 is connected with one group in the root of telescopic column 1 and tiltedly organizes sealing ring 12, the sealing ring 10 and flexible
Expansion bend 6 is provided between column 1, the expansion bend 6 is provided with laminate 8, is provided with spring 7 between the laminate 8, and the gland 2,
Asbestos board 5, sealing ring 10 and oblique group sealing ring 12 are socketed on telescopic column 1.
Preferably, the expansion bend 6 is fixed on telescopic column 1 by fastener, and can be radially movable；It is described close
Seal uses rubber seal, and using the rubber seal of Y types；The gland 2, sealing support 2 use Q235 steel materials.
Specifically used mode and advantage：The sealing mechanism of the novel central mechanism of vulcanizing machine, floating sealing are main
It is made up of seal receptacle, floating bushing, sealing ring, asbestos board and several parts of gland, seal receptacle is to be welded to connect with cylinder body.Sealing ring
Y type rubber seal is still used, is arranged on using two sealing rings backwards to opposed installation form outside floating bushing.Floating bushing exists
Can radially it be fluctuated in seal receptacle, the top of sealing ring is connected and fixed by asbestos board and gland by screw.In
The axial seal of heart pull bar is achieved by two sealing rings, while the floating bushing equipped with sealing ring can be with center pull rod
Circular runout fluctuated, reduce the stress of sealing ring, the service life of sealing ring extended, at center
The root of pull bar is mounted with that is tiltedly organized a sealing ring, makes with the mixture that telescopic column motion is brought in tiltedly quilt at group sealing ring
Block, because tiltedly group sealing ring is mounted in telescopic column root, expansion bend and the sealing support of its outer ring there are 2~3 mm
Gap, therefore sealing ring can carry out small range in radial direction with center pull rod and fluctuate, and thus subtract significantly
The extruding force for the telescopic column that small sealing ring is subject in radial direction, improves the stress of sealing ring, makes sealing ring
By being made a concerted effort originally by axial friction and radial compression power, it is changed into only by the frictional force of axial direction.The change of stress, makes
The abrasion condition of rubber seal has obtained preferable improvement, extends service life.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
