Description

Hollow roller

Technical Field

The utility model relates to the technical field of rollers, in particular to a hollow roller.

Background

The rollers are tools for generating plastic deformation to (rolling material) metal, are important consumption components for determining the efficiency of the rolling mill and the quality of the rolling material, are important parts on a rolling mill in a steel rolling mill, and roll and mill the steel material by using the pressure generated when a pair or a group of rollers roll; the existing hollow roller has a simpler structure in the aspect of heat dissipation inside the roller body, so that air flow in the roller body is slower in flowing and the heat dissipation effect is better, and therefore the hollow roller is provided.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a hollow roll that solves the problems set forth above in the background art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a hollow roll, includes the roll body, the cavity has been seted up in the roll body, the roll body left and right sides fixedly connected with connecting axle, first heat dissipation through-hole has been seted up in the connecting axle, and is two sets of the connecting axle opposite face stretches into to the roll body in, be equipped with hollow connecting pipe in the cavity, end fixed connection is on the connecting axle about the hollow connecting pipe, a plurality of groups of connecting rings of fixedly connected with on the hollow connecting pipe, fixedly connected with three flabellums of group on the connecting ring, a plurality of backup pads of group of fixedly connected with on the hollow connecting pipe.

As a further optimization of the technical scheme, the two groups of connecting shafts are provided with sleeving grooves.

As a further optimization of the technical scheme, a plurality of groups of through holes are formed in the hollow connecting pipe.

As a further optimization of the technical scheme, a plurality of groups of second heat dissipation through holes are formed in the left end and the right end of the roller body.

Compared with the prior art, the utility model has the beneficial effects that: when the roller starts to work, external air flow can enter the hollow connecting pipe through the first heat dissipation holes in the two groups of connecting shafts and then enter the cavity through the plurality of groups of through holes in the hollow pipe, the plurality of groups of fan blades positioned on the hollow connecting pipe move synchronously with the roller, the rotation of the fan blades drives the air in the cavity to flow, the air flow can be discharged or enter through the second heat dissipation holes, the air flow in the hollow roller is accelerated, and the heat dissipation effect is good.

In the figure: the roller comprises a roller body 1, a connecting ring 2, a supporting plate 3, a hollow connecting pipe 4, a through hole 5, a connecting shaft 6, a first heat dissipation through hole 601, a sleeving groove 7, fan blades 8, a second heat dissipation through hole 9 and a cavity 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a hollow roller, includes roll body 1, cavity 10 has been seted up in roll body 1, roll body 1 left and right sides fixedly connected with connecting axle 6, first heat dissipation through-hole 601 has been seted up in the connecting axle 6, and is two sets of 6 opposite faces of connecting axle stretch into to the roll body 1 in, be equipped with hollow connecting pipe 4 in the cavity 10, end fixed connection is on connecting axle 6 about hollow connecting pipe 4, fixedly connected with a plurality of groups connecting ring 2 on the hollow connecting pipe 4, fixedly connected with three flabellum 8 of group on the connecting ring 2.

Specifically, the two groups of connecting shafts 6 are provided with sleeving grooves 7.

Specifically, the hollow connecting pipe 4 is provided with a plurality of groups of through holes 5.

Specifically, a plurality of groups of second heat dissipation through holes 9 are formed in the left end and the right end of the roller body 1.

Specifically, a plurality of groups of supporting plates 3 are fixedly connected to the hollow connecting pipe 4.

In particular, the splicing groove 7 can be used for installing a rope when installing or dismantling the roller.

Specifically, the first heat dissipation through hole 601 and the second heat dissipation hole 9 can allow external air to flow into the roller.

Specifically, during the use, finish the roll installation and begin the during operation, first louvre 601 in two sets of connecting axles 6 of outside air current accessible enters into to hollow connecting pipe 4 in, again by a plurality of groups through-hole 5 on the hollow connecting pipe 4 enter into to cavity 10 in, a plurality of groups flabellum 8 that lie in on the hollow connecting pipe 4 this moment follow roll synchronous motion, the rotation of flabellum 8 drives the gas flow in the cavity 10, the air current is discharged through second louvre 9, gas flow in the hollow roll is with higher speed.
