Composite positive and negative roller bending device based on six-high mill

Abstract

The invention discloses a composite positive and negative roller bending device based on a six-high mill, comprising four roller bending cylinders. The four roller bending cylinders are respectively installed between an upper working roller bearing seat and a lower working roller bearing seat of the inlet and the outlet of the operation side and the inlet and the outlet of the transmission side, have a same structure and all consist of an upper pressure plate, a lower pressure plate, a cylinder cover, a fixed block, a cylinder body, a piston rod, a spherical cushion, a connecting rod, a guide key, a locking ring and a composite cylinder sleeve, wherein the cylinder body is installed in the fixed block, the upper end of the fixed block is connected with the cylinder cover, the cylinder cover is connected with the upper pressure plate, the upper pressure plate is installed in a T groove of the upper working roller bearing seat, a necking is arranged at the lower part of the cylinder body and is sleeved with the composite cylinder sleeve, the lower part of the composite cylinder sleeve is connected with the lower pressure plate, the lower pressure plate is installed in a T groove of the lower working roller bearing seat, the cylinder body, the cylinder cover and the piston rod form a roller bending hydraulic cylinder, the composite cylinder sleeve is connected with the piston rod, the spherical cushion, the connecting rod, the guide key and the locking ring to form a whole body and form a composite roller bending hydraulic cylinder, and the composite roller bending hydraulic cylinder can slide together with the roller bending hydraulic cylinder in the fixed block.

Description

technical field [0001] The invention relates to a control device or method using roll deflection, which is specially suitable for metal rolling mills or processed products thereof, and is used for rolling non-ferrous metal and alloy thin strips. Background technique [0002] In the work roll bending device of a traditional six-high rolling mill, the upper and lower rolls are set separately. Due to structural limitations, two hydraulic cylinders need to be arranged side by side at the entrance or exit of each work roll chock, such as figure 1 and figure 2 shown. Each rolling mill needs to install 16 positive and negative roll bending cylinders, and there are many pipelines, making maintenance very difficult. Contents of the invention [0003] The proposal of the present invention aims to design a composite positive and negative roll bending device based on a six-high rolling mill, so as to reduce the influence of pipeline leakage on the bending force of the rolling mill,...
