Problems solved by technology

[0004] However, in the first type of rotary joint, the hot straightening roller has a different shape and structure from the existing hot straightening roller, and has no protruding shaft diameter, so the water seal cannot be realized, and it cannot be connected to the blind hole of the existing hot straightening roller; The two types of rotary joints have only one water inlet, and the cooling water cannot be discharged again, so it is not suitable for the cooling of hot straightening rollers

Abstract

The invention relates to a water-cooled rotating joint device for a thermal straightening machine. The water-cooled rotating joint device for the thermal straightening machine comprises a flange (1),a stopper (2), a rotating joint part, a cooling water pipe (4), a supporting roller (5), a roller shaft (6) and a rivet (7). The rotating joint part includes a joint seat (40) and a bearing seat part(3). The joint seat (40) is fixedly connected with the bearing seat part (3), the bearing seat part (3) is fixedly connected with the flange (1), and the stopper (2) is installed on the lower side ofbearing seat part (3). One end of the cooling water pipe (4) penetrates through the flange (1), the bearing seat part (3) and the joint seat (40) from right to left in sequence, and the end part of the end of the cooling water pipe (4) is arranged on an inner wire connection hole (48) of the joint seat (40); and the roller shaft (6) is connected with the other end of the cooling water pipe (4) through the rivet (7), and the supporting roller (5) sleeves the roller shaft (6).

Description

technical field [0001] The invention belongs to the technical field of rolling mill mechanical cooling, and in particular relates to a water-cooled rotary joint device used for a hot straightening machine. Background technique [0002] In the production process of Laiwu Steel's wide and thick plates, hot straightening is an indispensable production process. Thermal straightening is generally carried out at 650-1000°C, which is suitable for medium and thick plates. Usually, the temperature of the hot straightening roll is relatively high, and water is needed for cooling. Inside the center of the hot straightening roller is a long blind hole structure, the rotary joint is connected with the blind hole of the hot straightening roller, and cooled by water. The rotary joint rotates forward or reverse due to the heat straightening roller, and the cooling water enters and exits through the rotary joint. The existing rotary joints have poor water tightness, easy water ingress in ...
