A roll changing connection device and roll changing method for an eighteen-high cold rolling mill

Abstract

The present invention relates to a roller replacement device for eighteen-roller cold rolling mill and roller replacement method. The device is placed on the driving side of the rolling mill. An inclined support plate part comprises an inclined support plate, and a connection hinge shaft sleeve integrally fixed with a connection hinge shaft. The lateral inner inclined plane of the inclined support plate intersects the horizontal underside in smooth transition. The inclined support plate is fixed on a fixing roller bending block for an intermediate roller. The connection hinge shaft sleeve, the connection hinge shaft and the tail extension end of the connection hinge shaft are integrally formed and work together. A connection hole end is disposed on the outer wall of the connection hinge shaft sleeve. A counter bored hole is formed on the connection hole end. While replacing the roller, the tail extension end of the connection hinge shaft slides along the inclined plane of the inclined support plate till it reaches the end point at the intersection of the inclined plane and the horizontal underside, and a pin roll is inserted into the hole of the connection hole end. After replacing the roller, the pin roll is pulled out of the hole. The device of the present invention has simple and small structure, convenient machining and manufacturing, and easy installation. The complete device can be easily adapted to the window design of the eighteen-roller cold rolling mill and can easily realize adjustment function.

Description

technical field [0001] The invention relates to a connecting device and method suitable for a roll changing process, in particular to a connecting device and a method suitable for a roll changing process of a backing system of an eighteen-high cold rolling mill. [0002] technical background [0003] With the rapid growth of the national economy, the demand for cold-rolled sheets continues to increase, but the quality of finished products of cold-rolled sheets in my country is not high, and there is still a large gap compared with foreign products, mainly in the chemical composition and mechanical properties. Stability, surface quality, shape and dimensional accuracy of finished strip steel. The fundamental reason is that the production scale of domestic cold-rolled sheet is small and the level of equipment is low. As far as the current situation is concerned, the 18-high cold rolling mill has more achievements in the production of high-strength strip steel such as stainless ...
