Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminum foil preparation technical field, especially relates to a bearing box dismounting device of aluminum foil rolling mill's work roll. BACKGROUND

[0002] In the preparation process of aluminum foil, rolling is a key step, which is carried out through multiple passes of rolling mill to make the aluminum foil thinner, more flexible and have certain strength.

[0003] Cold rolling mill usually uses multi-roll rolling mill, which includes two work rolls and two backup rolls. When the aluminum plate passes through the rolling mill, the work rolls press it to make it gradually thinner. During the cold rolling process, the roll gap of the rolling mill needs to be adjusted constantly to gradually reduce the thickness of the aluminum plate. By adjusting the width and position of the roll gap, effective rolling and plastic deformation of the aluminum plate can be achieved. Through the above cold rolling process, the aluminum plate can gradually reduce its thickness after multiple rolling, and finally be prepared into the required aluminum foil. The condition of the work roll is crucial for obtaining high-quality aluminum foil, ensuring that it has appropriate thickness, smoothness and mechanical properties to meet the requirements of various applications.

[0004] During each pass of rolling, the work roll will experience a certain degree of wear. This is because during the rolling process, the work roll is subjected to high pressure and friction, and is in contact with the surface of the aluminum plate and undergoes plastic deformation. Due to this friction and deformation, the surface of the work roll will gradually wear. In order to cope with this wear, the work roll needs to be regularly inspected, maintained and replaced. For example, through surface grinding or grinding, the smoothness and flatness of the work roll surface can be restored. Before the work roll is ground, the bearing box needs to be disassembled, and after the grinding process, the bearing box needs to be installed. The bearing box is relatively large and in order to reduce collision loss, it is usually realized through special equipment in the prior art.
