Aluminum coil segmentation method for reducing metal fatigue

Abstract

The invention provides an aluminum coil segmentation method for reducing metal fatigue, and belongs to the technical field of aluminum coil processing. The aluminum coil cutting method for reducing metal fatigue comprises the following steps that S1, an aluminum coil is arranged on an unwinding shaft of a cutting device, one end of the aluminum coil is cut open, two aluminum strip ports are formed, and the two aluminum strip ports correspondingly penetrate through a first guide pipe and a second guide pipe and are fixedly connected to two rotating rings; S2, the unwinding shaft and the rotating rings rotate, the aluminum strip is kept to be tightly attached to the inner surfaces of supporting blocks forming an annular supporting area, then the aluminum strip is gradually wound, and no gap exists after the aluminum strip is wound; S3, slitting is carried out till the aluminum roll on the unwinding shaft is completely cut; and S4, the two rotating rings are moved until the unwinding shaft is completely separated from the middles of the rotating rings, the two rotating rings are separated, the supporting area formed by the supporting blocks is removed, and the wound aluminum strip is loosened and sent out through a conveying belt structure.

Description

technical field [0001] The invention belongs to the technical field of aluminum coil processing, in particular to an aluminum coil splitting method for reducing metal fatigue. Background technique [0002] Metal fatigue refers to the process in which materials and components gradually produce local permanent cumulative damage in one or several places under the action of cyclic stress or cyclic strain, and cracks or sudden complete fracture occur after a certain number of cycles. When the material and structure are subjected to repeated load changes, although the stress value has never exceeded the strength limit of the material, even if it is lower than the elastic limit, damage may occur. The failure phenomenon of the structure is called the fatigue failure of the metal. [0003] When the aluminum coil is produced, it needs to be rolled. Before it is processed into an aluminum gusset, the aluminum coil needs to be cleaned and primed. Rolls produce metal fatigue. [0004]...

AI Technical Summary

Problems solved by technology

[0003] When aluminum coils are produced, they need to be rolled. Before being processed into aluminum gussets, the aluminum coils need to be cleaned and primed. The aluminum coil has been bent many times during the material process, which has caused metal fatigue to the aluminum coil

[0004] Before the aluminum coil is processed into sheets, it is necessary to divide the aluminum coil into the size of the width required by the aluminum gusset, but when dividing, the coil needs to be Unrolling, splitting, and then rolling again, the aluminum plate metal is fatigued, and the hardness is reduced, resulting in the aluminum gusset plate being easily deformed after forming
