Abstract

The invention relates to the field of metallurgical equipment, in particular to a floating oil return mechanism in a floating decoiler. The mechanism is characterized by at least comprising a sealing box body, a box cover, an oil inlet flange, a rubber sealing gasket, an oil inlet pipe, an oil return flange and an oil return pipe, wherein the oil return pipe is connected with an oil box of a thin oil lubrication station through an intermediate piping; the sealing box body is a welding structural member and fixed on a foundation; the oil inlet flange is fixed on the upper side part of the sealing box body; the oil inlet pipe is in rigid connection with the decoiler body; the oil return flange is fixed right below the sealing box body and connected with the oil return pipe; and the oil inlet pipe floats and stretches in the sealing box body through the guide of the oil inlet flange and the sealing of the rubber sealing gasket in the presence of the drive of the floating decoiler body to ensure that lubricating oil flows in the sealing box body and then flows back to the thin oil lubrication station through the oil return pipe at the bottom of the sealing box body. The floating oil return mechanism has simple structure, guarantees smooth oil return and is completely suitable for the floating oil return working conditions of the floating decoiler.

Description

technical field [0001] The invention relates to the field of metallurgical equipment, in particular to a floating oil return mechanism in a floating uncoiler of cold rolling, levelling, pickling, cleaning, tension leveling and shearing units. Background technique [0002] Among the floating uncoilers of cold rolling, tempering, pickling, cleaning, tension leveling and shearing units, most of the floating uncoilers are lubricated with thin oil circulation. In order to ensure that the strip center is always kept on the center line of the unit, the uncoiler has a The CPC automatic centering device, that is, the uncoiler body device floats in real time, and the lubricating oil return pipeline is generally directly connected with a hose to compensate for the floating amount of the uncoiler. Field practice shows that when hose connections are used, the hoses are often folded and flattened, resulting in serious oil return and affecting the lubrication effect, and sometimes the hose...
