Description

Technical Field

[0001] The utility model belongs to the field of aluminum foil rolling mill manufacturing and relates to an oil supply device for a spray bar beam used in a rolling oil cooling system of an aluminum foil rolling mill. Background Art

[0002] During the rolling process of the aluminum foil rolling mill, the rollers rotate at high speed and the temperature of the rollers is very high. In order to achieve the purpose of controlling the plate shape, the rollers must be cooled. At present, the rolling oil cooling system of the aluminum foil rolling mill is mainly composed of the rolling oil supply part, the oil temperature control part and the pressure automatic control part, the bypass filter part and the oil tank. The rolling oil supply part includes the upper and lower spray bar beams and the rolling oil supply system of the upper and lower spray bar beams. The existing rolling oil supply system usually uses pipes from the outside. Since the strip is relatively wide, there are many nozzles on the upper and lower spray bar beams, and the pipeline distribution is very complicated. In addition, the front part of the aluminum foil rolling mill itself is compact in structure and the space is very tight, which leads to messy and complicated piping on site, time-consuming and labor-intensive installation, low installation efficiency, large operating space occupation, small operating space, and inconvenience for operators to work; at the same time, the complex pipelines exposed to the rolling environment will also form condensed oil droplets on the surface, and the oil droplets will fall on the surface of the strip to contaminate the strip and affect the product quality; and the tensioning plate of the aluminum foil rolling mill is very close to the rollers. When the rolling mill changes the rollers, the tensioning plate needs to be moved out of the frame window position to make room for the roller system to move out, so the oil supply pipeline needs to move a stroke of about 300mm, and the telescopic amount is relatively large. In order to facilitate movement, the supply system uses more hoses. Since the existing metal hoses are easy to wear and tear, they are easy to be damaged and leak oil, have a short service life, and a low yield rate of plates and strips. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the prior art and to provide an oil supply device for a spray bar beam for a rolling oil cooling system of an aluminum foil rolling mill. The oil supply device reduces the external piping of the oil supply pipeline, so that the front part of the rolling mill is no longer messy, the oil supply pipeline is easy to install, the installation efficiency is high, the operating space is increased, the operator's work is convenient, the service life is long, the oil dripping points on the upper surface of the strip are reduced, and the plate and strip yield rate is improved.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the utility model opens an oil supply pipeline in the tubular base of the rolling mill to directly supply rolling oil to the lower spray rod beam, and also sets a built-in oil circuit in the two tensioning plates of the rolling mill. The oil supply pipeline in the tubular base is also connected to the built-in oil circuit of the two tensioning plates through a swivel joint assembly that can be rotated and stretched at will, and then supplies rolling oil to the upper spray rod beam through a rod-type oil outlet pipe.
