Abstract
The utility model relates to a cushion block pushing and pulling device of a rolling mill, which belongs to main equipment of rolling mills. The main function of the device is to reduce the stroke of a hydraulic AGC cylinder by using a cushion plate with a fixed thickness. The devices are respectively arranged on an operating side and a transmission side of the rolling mill, each device comprises a frame, a fixing support, a connecting beam, a fixing beam, a cushion block, a hydraulic cylinder, a clamp block, an AGC cylinder fixing block and the like. After total grinding quantity of a roller system of the rolling mill reaches a set value, the stroke of the ACG cylinder reaches a limit position, the device retracts the AGC cylinder, and a piston rod of the hydraulic cylinder of the cushion block pushing and pulling device extends out to push the cushion block into a space between the AGC cylinder and an upper supporting roller bearing support. The thickness of the cushion block is conventionally 100 millimeters, and the stroke of the AGC cylinder is compensated by means of increasing the number of the mechanical cushion blocks. In other words, the stroke of the AGC cylinder can be 100 millimeters smaller than actually required stroke in design, thereby the height of a hydraulic oil column of the AGC cylinder is shortened, and the effect of increasing the natural frequency and the response frequency of the AGC cylinder is realized.
