Description

Technical Field

[0001] The utility model relates to the technical field of short stress line rolling mills, in particular to a sealing structure of a bearing seat for assembling a roller system of a short stress line rolling mill. Background Art

[0002] The short stress line rolling mill is a new type of rolling mill. Its working principle is to adjust the position of the rollers so that the spacing between the rollers or the rolling force gradually decreases as the number of rolling times increases. When the number of rolling times reaches a certain level, the spacing between the rollers will become smaller, so that the metal sheet can be plastically deformed and processed. This rolling mill has the advantages of compact structure, small size, light weight, high rigidity, etc., and can obtain high-precision products. The rollers on the short stress line rolling mill are usually installed on the bearing seat, and the bearings on the bearing seat facilitate the rotation of the rollers to achieve the effect of processing the metal sheet;

[0003] In the prior art, a Chinese patent with a patent publication number of CN205966773U discloses a sealing structure of a lower bearing seat in a short stress line rolling mill roll assembly. The device adopts a sealing structure in which a pressure plate and a J-shaped sealing ring are arranged at the contact point between the lower bearing seat and the pressing screw. The sealing effect is good, and the production cost can be reduced, the accident rate can be reduced, and the production efficiency can be improved.

[0004] However, this device can only ensure the sealing between the bearing seat and the bearing, but cannot ensure that the oxidized iron sheet enters between the inner swivel ring and the outer swivel ring of the bearing in the bearing seat during rolling, which can easily lead to a shortened bearing life and even cause the bearing to be unable to rotate in severe cases. Therefore, a sealing structure for the bearing seat of a short stress line rolling mill roll system is designed to solve the above problem. Utility Model Content
