Claims

[Scope of utility model registration request]

A connecting shaft 10 in which a female threaded portion 14 is provided on a pair of opposing roll jocks 1 and 2, and has a male threaded portion 15 on its outer periphery that is screwed into the female threaded portion 14.
is inserted into both roll chocks 1 and 2 so as to be able to slide relative to each other in the axial direction and to be able to rotate relative to each other around the shaft center, and the female threaded portion 14 is screwed against the male thread 15 by the rotation of the connecting shaft 10 whose vertical movement is regulated. By advancing and retreating,
In a roll chock device of a rolling mill in which the interval between rolls supported by each roll chock 1, 2 is changed and adjusted, an oil chamber 16 is formed between the inner periphery of the roll chocks 1, 2 and the outer periphery of the connecting shaft 10. One end surface in the axial direction of the oil chamber 16 is formed by a pressure receiving surface 17 on the roll choke side, and the other end surface in the axial direction is formed by a pressure receiving surface 19 on the connecting shaft side, and furthermore, a means for supplying pressure oil to the oil chamber 16 is provided. , the pressure receiving surface 1
A roll chock device for a rolling mill, characterized in that the resultant force of hydraulic pressure acting on the roll jocks 1 and 2 through the roll jocks 1 and 2 in the direction of opposing and separating the roll jocks passes through the axis of the connecting shaft 10.
