Description

Technical Field

[0001] The utility model belongs to the technical field of rollers and relates to a reinforced roller structure. Background Art

[0002] The roller is a component on the rolling mill that causes the rolled metal to undergo plastic deformation. The shape, size and material of the roller must be adapted to the rolling mill and the rolled product. The roller is divided into cylindrical and non-cylindrical shapes according to the shape of the roller body. In order to save materials, the existing rollers are often designed to be hollow structures when producing rollers. Although raw materials are saved, due to the hollow structure of the roller; Patent No. CN202121589447.9 discloses a reinforced roller, which relates to the field of roller production technology. In view of the problem that the existing hollow rollers are easy to deform, the following solution is proposed, which includes a roller sleeve, an inner sliding surface of the roller sleeve A positioning plate is sleeved, a reinforcing shaft is fixedly sleeved in the middle of the positioning plate, two symmetrical pneumatic cylinders are fixedly connected to the inner side of the reinforcing shaft, the output end of the pneumatic cylinder is fixedly connected to a push plate slidably connected to the inner side of the reinforcing shaft, the outer side of the push plate is fixedly connected to a sliding sleeve slidably sleeved to the outer side of the reinforcing shaft, one side of the sliding sleeve is rotatably connected to multiple first connecting rods, one end of the multiple first connecting rods is rotatably connected to a second connecting rod rotatably connected to one side of the positioning plate. The utility model has a simple structure, can improve the rigidity of the hollow roller, prevent the roller from being deformed due to excessive pressure on the roller during use, and is simple to operate and easy to use.

[0003] The disadvantage of the above-disclosed rolling mill is that both the rolling mill sleeve and the reinforced shaft are integral structures. When one side of the rolling mill is worn and the other side is intact, a better integrated rolling mill is needed, which undoubtedly causes an increase in the cost of use and a decrease in the production progress. For this reason, we design a reinforced rolling mill structure. Summary of the invention
