Adjusting device for oil cylinder inclined iron for side support of work roll in 18-high rolling mill

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to a hydraulic cylinder inclined iron adjustment device of eighteen rolling mill working roll side supports. The hydraulic cylinder inclined iron adjustment device comprises a first memorial archway, a second memorial archway, eight backing rolls, four side supporting rolls, two middle rolls, two working rolls and two supporting rolls, wherein the working rolls are supported by the supporting rolls through the middle rolls, and the middle rolls are installed on middle roll bearing seats arranged between the two memorial archways. A hydraulic cylinder base is installed on the inner side of the second memorial archway, an ejection hydraulic cylinder is installed on the hydraulic cylinder base, and a push rod of the ejection hydraulic cylinder abuts against the backing beam on one side of the second memorial archway. A worm gear case motor is installed on the transmission side of the first memorial archway, the output end of the worm gear case motor is connected with a connecting rod through a first coupler, and the other end of the connecting rod is connected with a worm gear case through a second coupler. The adjustment device is simple in structure, easy to machine, and convenient and fast to adjust and maintain.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to an oil cylinder inclined iron adjustment device for side support of working rolls of an 18-high rolling mill. Background technique [0002] With the continuous development of my country's national economy, the demand for cold-rolled stainless steel strips and silicon steel strips continues to increase, and multi-roll cold rolling mills have also been rapidly developed and widely used. Eighteen-high rolling mills have been developed for rolling such steel strips. [0003] At present, the side support device of the middle roll of the 18-high rolling mill commonly used is complex and bulky in structure, difficult to manufacture, requires high machining accuracy, and the middle roll is long. It is inconvenient to adjust and maintain in the subsequent use process, and the equipment cost is high. Contents of the invention [0004] The object of the present i...
