Embodiment 1

[0063] Take the water-cooled cooling bed device of billet turning gear wheel as an example, such as figure 1 , figure 2 , image 3 and Figure 13 As shown, the hot steel billet X is transported in the direction of Xa→Xb, that is, at the starting position Xa of the billet on the bed, it starts to rotate with each water-cooled toothed wheel 2, and the hot steel billet X is transferred to the next water-cooled toothed wheel 2 until the steel billet goes down. Bed end position Xb gets out of bed and ends. When each water-cooled toothed wheel 2 turns over the hot billet X, it goes through the process of turning → natural air cooling → straightening → transportation.

[0064] The water cooling of the present invention is used for the cooling of the mechanical equipment body, such as figure 1 , figure 2 , image 3 and Figure 13 As shown, one way of cooling water: from the water inlet branch pipe Jn on the water inlet pipe main pipe J, directly flows into each cooling bearin...

Embodiment 2

[0079] Such as figure 1 , figure 2 , Figure 10 , Figure 11 and Figure 12 As shown, a set of two-way rotary joint 5 is installed at the non-transmission side end of each water-cooled transmission shaft 1. Technical parameters: the cooling medium is industrial water, the working pressure is 0.3-0.4MPa, there is pressure return water, and the water flow rate is 2t / h, inlet water temperature ≤ 25°C, return water temperature ≤ 55°C. Design structure: the Y diameter of the water inlet main pipe is 50mm, the Z diameter of the return water main pipe is 150mm, the transparent ring 102 has through holes evenly distributed 8-Φ35mm, and the outer diameter of the composite rubber sleeve 101 is embedded in the concave end Y' of the water inlet main pipe The inner diameter of the composite rubber sleeve 101 is a tapered hole type, so that the fit between the outer cones at the convex end Y” of the water inlet main pipe is tight; the large-diameter end of the composite rubber 101 is ...

Embodiment 3

[0081] Basically the same as embodiment 2, such as image 3 , Figure 7 , Figure 8 , Figure 9 As shown, the half-toothed wheel 201 in the water-cooled toothed wheel 2 adopts steel structure weldment, and the welded steel that does not directly contact with the billet adopts Q345-B steel structure weldment; and the tooth-shaped working surface 203 adopts 42CrCo wear-resistant The impact material, heat treatment and quenching of the working surface, and the cooling water have played a role in high temperature resistance for the material used for the toothed working surface 203, greatly prolonging the service life of the water-cooled toothed wheel 2.

A driving device and a turning mechanism each comprises a water-cooling system, the turning mechanism comprises multiple rows of driving shafts which are arranged in parallel, each row of the driving shaft is composed of multiple water-cooling driving shafts which are sequentially connected through couplings, water-cooling toothed wheels are evenly arranged on each row of the driving shaft, the water-cooling toothed wheels on the two adjacent rows of the driving shafts are arranged in the same mode, positions of the water-cooling toothed wheels of the two adjacent rows of the driving shafts are staggered, each row of the driving shaft is supported through cooling bearing seats, and the water-cooling driving shafts, the water-cooling toothed wheels, the couplings and the cooling bearing seats are each internally provided with a water-cooling cavity. The steel billet turning water-cooling bed device has the advantages that a machined workpiece cooled through water is long, working of the working face is long lasting, and the cooling efficiency is high.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, more specifically, to a billet turning water-cooling cooling bed device. Background technique [0002] In the continuous casting and rolling production line, when the billet turning U-V tooth plate or toothed wheel cooling bed device is used to receive hot billets of various specifications for turning cooling and straightening, the effective cooling length of the cooling bed equipment is 12-60m, and the cooling width is 9- 14m. The temperature of the upper cooling bed of the hot billet is 850°C, and the temperature of the lower cooling bed of the hot billet is controlled below 350°C. The existing technology is that the U-V tooth plates on the billet turning U-V tooth plate cooling bed device are mutually exchanged to support the hot steel billet to be continuously turned over and transported, or the toothed wheel on the steel billet turning toothed wheel cooling bed device directly support...
