Description
Technical field
The utility model is related to sleeve technology field, specially a kind of wear sleeve.
Background technology
It wears no resistance more currently, common inner sleeve exists, easily wears, service life is low, replaces frequent, replacement liner plate
Tedious process, the problems such as seriously affecting production, therefore, there is an urgent need for be improved to inner sleeve.
Utility model content
The purpose of this utility model is to provide a kind of wear sleeves, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model provides the following technical solutions：A kind of wear sleeve, including cylinder, it is described
Cylinder is cylindrical structure, is bonded multiple wear-resistant sleeves on the cylinder body outer wall from top to bottom, compound anti-on the wear-resistant sleeve outer wall
The upper and lower end of laminate layer, the cylinder body outer wall is provided with card slot, is connected with stirrup ring in the card slot, in the cylinder
Nanocrystalline alloy coating is coated on wall.
Preferably, the wear-resistant sleeve uses ceramic jacket, the ceramic jacket to be bonded cylinder body outer wall by ceramic abrasionproof adhesive.
Preferably, the resistance to compression layer uses 17CrNiMo carbon steel materials.
Preferably, the nanocrystalline alloy coating uses Ti-48Al-8Cr-2Ag nanocrystalline coatings.
Preferably, the thickness of the wear-resistant sleeve is 2mm-4mm.
Compared with prior art, the utility model has the beneficial effects that：
（1）The utility model is simple in structure, wherein multiple wear-resistant sleeves is bonded on cylinder body outer wall from top to bottom, outside wear-resistant sleeve
Composite compression-resisting layer on wall, wear-resistant sleeve use ceramic jacket, ceramic jacket to be bonded cylinder body outer wall, the pottery of bonding by ceramic abrasionproof adhesive
Insulator can effectively prevent the abrasion of sleeve outer wall, in addition, ceramic jacket itself has excellent wear-resisting property, outside wear-resistant sleeve
Compound 17CrNiMo carbon steel material resistance to compression layers on wall, additionally it is possible to play the role of protecting wear-resistant sleeve, further extend sleeve
Service life.
（2）In the utility model, the upper and lower end of cylinder body outer wall is provided with card slot, and stirrup is connected in card slot
Ring can effectively prevent the cracking phenomenon of sleeve both ends nozzle using this structure.
（3）Ti-48Al-8Cr-2Ag nanocrystalline coatings are coated in the utility model, on cylinder inboard wall, it can be effective
Cylinder inboard wall is protected, prevents corrosion, wear phenomenon, and then extend sleeve service life.
Description of the drawings
Fig. 1 is the utility model overall structure front view；
Fig. 2 is the utility model sleeve lining front view.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of wear sleeve, including cylinder 1, the cylinder
Body 1 is cylindrical structure, is bonded multiple wear-resistant sleeves 2 on 1 outer wall of the cylinder from top to bottom, compound on 2 outer wall of the wear-resistant sleeve
The upper and lower end of resistance to compression layer 3,1 outer wall of the cylinder is provided with card slot 4, and stirrup ring 5 is connected in the card slot 4, is adopted
With this structure, the cracking phenomenon of sleeve both ends nozzle can be effectively prevented；It is coated with nanocrystalline conjunction on 1 inner wall of the cylinder
Gold plating 6；Wear-resistant sleeve 2 uses ceramic jacket, the ceramic jacket to be bonded 1 outer wall of cylinder by ceramic abrasionproof adhesive, wear-resistant sleeve 2
Thickness is 2mm-4mm；Resistance to compression layer 3 uses 17CrNiMo carbon steel materials.The ceramic jacket of bonding can effectively prevent sleeve outer wall
Abrasion, in addition, ceramic jacket itself has excellent wear-resisting property, the compound 17CrNiMo carbon steel materials on wear-resistant sleeve outer wall
Matter resistance to compression layer, additionally it is possible to play the role of protecting wear-resistant sleeve, further extend the service life of sleeve.
In the utility model, nanocrystalline alloy coating 6 uses Ti-48Al-8Cr-2Ag nanocrystalline coatings.It can be effective
Cylinder inboard wall is protected, prevents corrosion, wear phenomenon, and then extend sleeve service life.
In conclusion the utility model is simple in structure, there is excellent wear-resisting, compressive property, wear rate can be reduced, had
The service life for extending sleeve of effect.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
