Embodiment 1

[0049] combine figure 1 , 2 , the billet toothed wheel turning cooling bed device of the present embodiment, the main components are as follows:

[0050] Main transmission 1, one piece, as power system.

[0051] The constant speed transmission device 2 includes a lower casing 201 and an upper casing 202 .

[0052] Nine sets, as a component assembly, the torque magnitude of the input shaft and the output shaft is the same as the rotational speed.

[0053] Coupling 3, thirty-two sets.

[0054] Bearing supporting parts 4, forty-four sets, as assembly parts, adopt split type rolling bearing 411 to do support. The split rolling bearing 411 is a split self-lubricating rolling bearing.

[0055] There are one hundred and seventy-six sets of toothed wheels 5; in order to improve the wear resistance of the material, the toothed working surface 502 on the toothed wheel 5 is quenched. The toothed wheel 5 has 4 to 6 equal tooth shapes, the toothed wheel 5 is split, and the two parts ...

Embodiment 2

[0074] The difference from Embodiment 1 is that the tooth-shaped working surface 502 on the toothed wheel 5 is inlaid with wear-resistant and high-temperature-resistant materials to improve the service life of the materials. Toothed wheel 5 is made up of 4 equal tooth profiles. In this embodiment, the time for the billet to get off the bed from the bed is 40 minutes.

Embodiment 3

[0076] The difference from Embodiment 1 is that the bearing seat 4 is a split self-lubricating sliding bearing. Toothed wheel 5 is made up of 5 equal tooth profiles. In this embodiment, the time for the billet to get off the bed from the bed is 35 minutes.

Abstract

The invention discloses a billet turn-over cooling bed device and belongs to the field of metallurgical equipment. The billet turn-over cooling bed device comprises a transmission device and a turn-over mechanism, wherein the transmission device drives the turn-over mechanism to turn over billets, the transmission device comprises a main transmission device and a constant-speed transmission set device, the main transmission device transmits torque to the constant-speed transmission set device, the constant-speed transmission set device is connected with the turn-over mechanism through a coupler, the turn-over mechanism comprises a plurality of transmission shafts distributed in parallel, the ends of the transmission shafts are connected to the coupler, tooth-shaped gears are evenly distributed on each transmission shaft, the tooth-shaped gears on every two adjacent transmission shafts are distributed in the same way, and the tooth-shaped gears on every two adjacent transmission shafts are staggered in position. With the device, hot square billets can be turned over, evenly cooled and automatically straightened efficiently, evenly and stably, and therefore the billets can be cooled sufficiently, the quality of the billets and smooth conveying of the billets can be guaranteed, and it is guaranteed that the tooth-shaped gears can support the tooth faces of the billets to normally turn over the billets.

Description

technical field [0001] The invention belongs to the field of metallurgical equipment, and more specifically relates to a billet turning cooling bed device. Background technique [0002] In the continuous casting and rolling production line, the U-V turning cooling bed is used to turn over, cool and straighten the hot steel billets of various specifications. The bed temperature of the hot billet is 850°C, and the bed temperature of the hot billet is controlled below 350°C. The existing technology is composed of the transmission device in the U-V turning cooling bed, the U-V tooth plate, the main shaft, the lifting and moving eccentric wheel group, the balance bracket and the roller, the moving beam and other components. The working principle of the system is that the motor drives the reducer and the main shaft. When two sets of eccentric wheel sets are installed on the main shaft with a phase difference of 180°, and the bearings are rotated through the eccentric wheels, each...
