Description

Synchronous link mechanism is hung in centre Technical Field The utility model relates to the technical field of cold rolling mills, in particular to a synchronous link mechanism for intermediate hanging. Background The 20-roll cold rolling mill belongs to high-end equipment in the metallurgical cold-rolled strip steel industry, is a minimum equipment which is indispensable in the fields of aerospace, civilian, chips and the like because of a plurality of plate type adjustment means, can roll extremely thin strips, can roll 0.005mm at the minimum, can roll stainless steel, alloy steel, titanium alloy, silicon steel, carbon steel and nonferrous metals, can realize large-rolling-force and small-roll-diameter rolling, and has a plurality of plate type adjustment means such as plate type convexity adjustment, middle channeling and the like. The traditional drawing type roller shifting structure is used for hanging an intermediate roller through an oil cylinder and a connecting rod structure, and in a roller changing state, the roller shifting structure is lifted through the oil cylinder, but the improved pushing type structure cannot be used for directly arranging the connecting rod on the intermediate roller due to structural limitation, and the intermediate roller needs to be prevented from falling off during roller changing. Therefore, there is a need for an intermediate suspension synchronous linkage mechanism to solve the above-mentioned technical problems.
