Abstract
A combination seal of a rolling mill working roll includes a seal body in annular structure, a internal lip, a external lip and a third lip formed from the extension of a fixed part and a self-fixed part, the internal lip, the external lip and the third lip protruded from the internal surface of the seal body and a framework embedded in the seal body. The combination seal of the utility model adopts the combination structure of the framework and a plurality of lips to replace the structure formed form a primary metal cover cup and one lip rubber seal ring. The combination seal of a plurality of lips is equivalent to the combination of a plurality of seals and a plurality of lips are distributed in turn with a hierarchy, the external lip lightening the concussion of cooling water while the internal lip stopping the infiltration of the cooling water and a ferric oxide scrap iron. In this way, a plurality of lips preventing the cooling water and the ferric oxide scrap iron from entering a bearing box in a work environment can be realized with an improved seal effect.
Description
Technical field
The utility model relates to a kind of sealing technique, is a kind of the combined sealed of operation roll of mill that be used for specifically.
Background technique
The operation roll of mill sealing is as Fig. 1, and it is made up of rubber seal 10 and wherein skeleton 20 and metal shroud ring 30, and its effect is to prevent that cooling water and hammer scale from entering the barrier of bearing housing.Sealing 10 has lip 101 one, and rubber seal 10 is fixed on the bearing housing 40 by the metal shroud ring 30 of outside, and the magnitude of interference of design is bigger.In the roughing mill zone, the ambient temperature height of work roll 50 sealings, impact that is subjected to and vibrations are frequent, often cause lip 101 wearing and tearing of sealing very fast, a large amount of cooling waters and hammer scale pass through sealing and enter bearing housing 40, cause the emulsification of lubricant and the variable color of bearing, the roller neck blackout is dry, bearing lubrication is bad, thereby influences the normal operation circumstances of roller assembly, until the damage that causes bearing and roller neck.
Summary of the invention
The purpose of this utility model is to design a kind of operation roll of mill combination seal, utilizes the useful space at roller neck place, and sealing is designed to have the combination seal with a plurality of sealing functions that the multiple tracks lip connects one, improves the actual effect of sealing.
For achieving the above object, the technical solution of the utility model is: the operation roll of mill combination seal, comprise, seal, it is a ring structure, comprise fixing part, from inner lip, outer lip and the 3rd lip that fixing part extends to form, this inner lip, outer lip and the 3rd lip are raised in the seal internal surface; Skeleton is embedded in the seal.
Again, also have overflow on the described seal, under the working condition that impacts and shake, can avoid cooling water and the hammer scale deposition between seal lip.
Described frame configuration and seal coupling is extended along seal, guaranteeing the intensity of seal, and novel combination seal to make be the sealing that elastic gel and skeleton is bonded together with the heat-vulcanized method.
The extension part that described skeleton comprises fixing part, extends to form from fixing part.
Lip: the outer end structural change of metal shroud ring is become one group of lip, and such and original lip is combined the combination seal that forms a plurality of lips.
Seal: metal shroud ring and sealing unite two into one and form a whole, and the shape of metal frame is done corresponding the improvement,
The beneficial effects of the utility model
1. good sealing effect.In rolling process, combination seal has prevented that effectively cooling water and hammer scale from entering in the bearing housing.
2. rational in infrastructure.A plurality of lips of combination seal play a role simultaneously, and cooling water and hammer scale are formed successive barriers, and the bottom spillway hole of sealing can be dredged the cooling water deposition between the seal lip.
3. installation and maintenance are simplified.Because sealing and shroud ring are combined into one, and have simplified the installation process of bearing housing.
4. the life-span is long.Combination seal is because the sealing of adopting a plurality of lips to form, good sealing effect, and the magnitude of interference of lip reduces relatively, and Mi Feng working life is longer like this.
The drawing explanation
Fig. 1 is the structure and the scheme of installation of former sealing.
Fig. 2 is a structure sectional view of the present utility model.
Embodiment
Referring to Fig. 2, operation roll of mill combination seal of the present utility model, comprise, seal 1, it is a ring structure, comprise that fixing part 11, the 3rd lip 12, inner lip 13 and outer lip 14, the three lips 12, inner lip 13 and the outer lip 14 that extend to form from fixing part 11 are raised in seal 1 internal surface 15; Skeleton 2 is embedded in the seal 1.
Again, also have overflow on the described seal, under the working condition that impacts and shake, can avoid cooling water and the hammer scale deposition between seal lip.
Described skeleton 2 shapes and seal 1 coupling is extended along seal 1, guaranteeing the intensity of seal 1, and the extension part 22 that it comprises fixing part 21, extends to form from fixing part 21; It is to bond together with skeleton 2 with the seal 1 of heat-vulcanized method with elastic gel.
By combination seal, a large amount of cooling waters and hammer scale can't pass through the bearing housing 4 that sealing enters work roll 3 roll neck portions.
Combination seal of the present utility model adopts skeleton to substitute the structure of original metal shroud ring and lip rubber seal composition with the composite structure of multiple tracks lip.This combination seal with multiple tracks lip is equivalent to a plurality of seal combination together, the multiple tracks lip is stratified to distribute successively, outer field lip alleviates the impact of cooling water, the infiltration that the lip of internal layer stops cooling water and hammer scale can realize that so a plurality of lips stop that simultaneously cooling water and hammer scale in the working environment enter in the bearing housing.The effect of sealing is significantly improved.
Claims (4)
1. the operation roll of mill combination seal is characterized in that, comprise,
