Embodiment Construction

[0022] Please refer to Fig. 1 and Fig. 2. Fig. 1 is an axial sectional view of Embodiment 1 of the backing roller mandrel of the present invention, and Fig. 2 is a left view of Embodiment 1 of the backing roller mandrel of the present invention, combined with Fig. 1 and Fig. 2 The structure of the present invention can be understood more clearly. As shown in the figure, the mandrel of the backing roller includes a shaft body 1, and the shaft body 1 has a channel 2 in the axial direction for conveying lubricating oil. middle. The shaft body 1 is radially opened with an oil hole 3 , and the oil hole 3 penetrates through the channel 2 from the outer surface of the core shaft body 1 . The lubricating oil seeps out through the oil hole 3, and the backing roller bearing is installed at the position of the oil hole 3, the outer surface of the bearing is in contact with the middle support roller, and the inner surface of the bearing is in contact with the outer surface of the mandrel...

Abstract

A mandrel of baking roller for improving the lubrication effect has an axial lubricating oil channel with one or more radial oil releasing holes whose surficial ends are on the bottom of a ring slot.

Description

technical field [0001] The invention relates to the field of friction lubrication of rolling mills, in particular to a backing roll mandrel structure for improving the frictional lubrication efficiency of rolling mills. Background technique [0002] In the structure of the plate rolling mill, in order to improve the rigidity of the rolled steel plate and meet the processing requirements of different plates, the backing roll is often used to support the middle support roll, such as in the tower roll system, 12-roll mill, 20-roll In the rolling mill, the backing rolls are used to support the intermediate support rolls. The difference is that the former uses three backing rolls, and the latter uses four backing rolls. The backing rolls are in contact with the intermediate support rolls through bearings. When working, the pressure from the work roll is transmitted to the backing roll through the intermediate support roll, and the backing roll bears the load from the multi-roll m...
