Description

Technical Field

[0001] The utility model relates to the technical field of hot rolling equipment, and specifically provides a rectangular billet turning device and a hot rolling roller table. Background Art

[0002] Hot rolling bar lines mainly use rectangular billets and round billets for production. Rectangular billets are usually placed flat before entering the heating furnace. Rectangular billets need to be placed vertically into the furnace to improve heating and rolling efficiency.

[0003] The turning mechanism of the turning device in the existing technology rotates around a fixed axis. After the workpiece is turned over, the center line of the workpiece will shift horizontally. Since the steel rolling production line is a continuous production, the steel billet is delivered to the furnace mouth by a conveyor roller. The turning device needs to be installed on the roller to turn it online, and the center line cannot change. Conventional turning devices cannot meet the requirements.

[0004] Accordingly, the art requires a new rectangular billet turning device and hot rolling roller to solve the above technical problems. Utility Model Content

[0012] The first rotating shaft, the second rotating shaft, the third rotating shaft, the fourth rotating shaft, the fifth rotating shaft, and the sixth rotating shaft are parallel to each other;

[0013] The pull rod, the base, the positioning rod and the first side wall form a four-bar linkage mechanism. When the pull rod in the four-bar linkage mechanism is in the first position, the second rotating shaft moves closer to the fourth rotating shaft, the first end of the positioning rod is tilted, and the first side wall is in a vertical state; when the pull rod is in the second position, the second rotating shaft is separated from the fourth rotating shaft, the first end of the positioning rod descends, and the side wall is in a horizontal state. The first side wall of the first position and the first side wall of the second position are in a right-angle structure, so that the vertical angle space is always in the same position.

[0014] Based on the above settings, the stable clamping and efficient flipping of the square billet steel are achieved through the constructed four-bar linkage and steel flipping arm design, so that the vertical angle space is always in the same position. Therefore, the precise positioning of the square billet can be maintained during the production process, which improves the production efficiency and the accuracy of the square billet flipping, and reduces the errors and the need for repositioning during the production process.

[0017] In the preferred technical solution of the above rectangular billet turning device, the second rotating shaft is fixed to the steel turning arm via an ear seat, and the third rotating shaft is fixed to the base via the ear seat.

[0018] Based on the above configuration, the second and third rotating shafts are fixed using ear seats, which ensures that the connection points are more stable, avoids wear and loosening problems during long-term use, and improves the stability and durability of the entire flip device.

[0019] In the preferred technical solution of the above-mentioned rectangular billet turning device, the turning device further includes a limiting bracket, and the limiting bracket is arranged on the side wall of the steel turning arm to limit the turning angle of the steel turning arm.

[0020] Based on the above settings, the flipping angle of the steel flipping arm is limited by the limit bracket to prevent excessive flipping from causing damage to the equipment, thereby extending the service life of the equipment and ensuring the safety of operation.

[0021] In the preferred technical solution of the above rectangular billet turning device, an anti-collision damping lever is further provided on the base to reduce the impact force generated when the steel turning arm contacts the base.

[0022] Based on the above settings, the anti-collision damping lever can reduce the impact force when the flip steel arm contacts the base, reduce equipment loss caused by impact, reduce noise, protect the equipment body, and improve the comfort of the working environment.

[0023] In a second aspect, the present invention provides a hot rolling roller, wherein the hot rolling roller comprises any one of the above-mentioned rectangular billet turning devices.

[0024] Based on the above settings, the billet turning in the hot rolling production line can be made easier and more efficient, which promotes the continuity of the production process and improves production efficiency, reduces the need for manual operation, and achieves the purpose of automated production.

[0025] In the preferred technical solution of the above hot rolling roller, a detection switch is provided on the hot rolling roller, and the detection switch is electrically connected to the turning device to control the operation of the turning device by detecting the position of the workpiece on the hot rolling roller.

[0026] Based on the above settings, it is possible to link with the turning device through electrical signals to realize automatic detection of the workpiece position, thereby controlling the start and stop and flipping time of the turning device, realizing a more intelligent production process, improving production accuracy and reducing unnecessary delays.
