Improvement method for finishing and trimming of double-zero foil material

Abstract

The invention discloses an improvement method of finishing and trimming of a double-zero foil material. According to the improvement method, the shearing overlapping amount of a cutting disc and the winding speed and the winding tension of a winding sleeve are adjusted according to the plate type condition of a material roll, when the measurement result is within the range of a standard plate type, it can be guaranteed that the winding sleeve conducts winding evenly, cutting of the cutting disc is free of vertical edges, and the material roll is wound normally without sticking damage; and when the measurement result exceeds the range of the standard plate type, vertical edges at the edge part of the material roll are reduced by reducing the shearing overlapping amount and reducing the rolling speed and the rolling tension of the rolling sleeve, and the phenomenon of adhesion between adjacent material roll layers due to vertical edge accumulation is improved.

Description

technical field [0001] The invention relates to an improved method, in particular to an improved method for finishing trimming of double-zero foil materials. Background technique [0002] Finishing shearing machine is a machine that can cut or cut plates and profiles into required sizes. When using the finishing shearing machine to trim the edges to produce double-zero foil materials in 1235AH14 state, due to the shape of the foil material is often Changes, when the double-zero foil material sleeve is selected improperly or the process parameters are not given properly, it will cause local sticking on the edge of the double-zero foil material after shearing, which will break the skin on the upper and lower surfaces of the sticky area , directly affects the product quality of the upper and lower surfaces of the sticky part after shearing and coiling, and because the thickness of the damaged skin area is smaller than the thickness of the normal area, the area where the skin da...
