DE-STACKING PROCESS FOR THE SEPARATION OF LUBRICATED ALUMINUM SHEETS

摘要

Described herein is a novel process for separating individual lubricated aluminum sheets from a stack of lubricated aluminum sheets as they enter a stamping press for fabrication. The process involves placing a lift underneath a stack of aluminum sheets and lifting the center upwards. This in turn causes the edges of the stack to bend downwards, creating a concave bending curvature facing the lift. The induced curvature is sufficient to provide the inter-sheet shear necessary to break the adhesion caused by the lubricant.

1. A method of separating stacked lubricated aluminum sheets, comprising:
a) placing a lift underneath the stack of lubricated aluminum sheets, wherein the lift imparts a clearance of the stack to cause the edges of the aluminum sheets to bend downwards, creating a concave bending curvature facing the lift; b) separating a top aluminum sheet at its edges from the stack; and c) individually separating the aluminum sheets from the stack.
