Description
Technical Field
The utility model relates to a processing equipment field especially relates to a high strength roll.
Background
With the continuous development of society, the roller industry is widely applied; the roller is a main working component and a tool for generating continuous plastic deformation on metal on the rolling mill; the variety and the manufacturing process of the roller are continuously developed along with the progress of metallurgical technology and the evolution of steel rolling equipment; the roller is easy to wear and scrap after being used for a long time, and the whole roller can only be discarded due to the traditional manufacturing mode and the matching mode, so that the roller is greatly wasted.
The main wear and abandonment of the traditional roller is the cracks generated on the surface and inside of the roller due to the overheated and overcooled working temperature, so that the temperature difference of the roller during working is reduced, the crack phenomenon is avoided, and the damage reporting rate is reduced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a high-strength roller can solve the problem that the background art provided.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a high strength roll, includes a structure main part, structure main part is equipped with open-ended roll body and roller including being cylinder and both ends, the roll body cover in the outside of roller, be equipped with the cooling channel around centre of a circle equidistance distribution in the roll body, the cooling channel transversely runs through the roll body, the inboard of cooling channel is equipped with the prevention of seepage permeable course.
Furthermore, the opening part is provided with a bearing, and the bearing is sleeved on the outer side of the roll shaft.
Furthermore, the roller body, the bearing and the roller shaft are all tightly connected.
Further, both ends of the roll shaft are provided with mounting parts.
Further, the outer side of the roller body is a smooth surface.
Further, the outer side of the roll body is coated with a heat-resistant coating.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model relates to a high-strength roller which adopts a structure that a roller body is separately connected with a roller shaft; one of the roller body and the roller shaft is scrapped without influencing the continuous cyclic utilization of the other one; meanwhile, the roller shafts and the roller bodies with different sizes can meet the connection requirement through customizing bearings with different sizes; the surface of the roller body is sprayed with heat-resistant emulsion, so that the probability of generating cracks due to heating of the roller body is reduced; the cooling holes in the roller body can also help the roller to realize the cooling effect, thereby improving the strength of the roller body and reducing the damage reporting rate of the roller.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A high strength roll of the present invention will be described in detail with reference to fig. 1 to 3: the utility model provides a high strength roll, includes a structure main part, structure main part is equipped with open-ended roll body 1 and roller 3 including being cylinder and both ends, 1 cover of roll body in the outside of roller 3, be equipped with the cooling channel 4 around centre of a circle equidistance distribution in the roll body 1, cooling channel 4 transversely runs through roll body 1, the inboard of cooling channel 4 is equipped with prevention of seepage layer 6.
A bearing 2 is arranged at the opening, and the bearing 2 is sleeved outside the roll shaft 3; the roller body 1, the bearing 2 and the roller shaft 3 are all tightly connected; mounting pieces 5 are arranged at two ends of the roll shaft 3; the outer side of the roller body 1 is a smooth surface; the outside of the roll body 1 is coated with a heat-resistant coating 7.
The working principle is as follows: the roller body 1 is connected with two bearings 2, and the roller shaft 3 is connected with the bearings 2 and mutually fastened and connected; the heat-resistant coating 7 on the surface of the roller body 1 can improve the heat resistance of the surface; the cooling channel 4 is arranged and cooling water is introduced into the cooling channel to help the roll body 1 to be cooled, so that the temperature difference during cooling is reduced, the probability of generating cracks is reduced, and the side surface embodies high strength; the roller shaft 3 can be fixedly connected to the gear unit by means of the mounting 5.
In summary, the high-strength roller of the utility model adopts a structure that the roller body and the roller shaft are separately connected; one of the roller body and the roller shaft is scrapped without influencing the continuous cyclic utilization of the other one; meanwhile, the roller shafts and the roller bodies with different sizes can meet the connection requirement through customizing bearings with different sizes; the surface of the roller body is sprayed with heat-resistant emulsion, so that the probability of generating cracks due to heating of the roller body is reduced; the cooling holes in the roller body can also help the roller to realize the cooling effect, thereby improving the strength of the roller body and reducing the damage reporting rate of the roller.
