Anode electrode tab punching device and anode electrode tab

Abstract

The present application relates to anode electrode sheet stamping technology field, specifically proposes an anode electrode sheet stamping device and an anode electrode sheet, including frame, upper die assembly and lower die assembly, upper die assembly and lower die assembly are installed on the surface of frame, upper die assembly does vertical reciprocating motion relative to lower die assembly under the drive of drive mechanism;The present application adopts the cutting knife body structure of four arc-shaped cutting edges and four V-shaped cutting edges integrated, changes the overall blanking mode of traditional flat blade edge, the four corner positions of the anode electrode sheet correspond to the arc-shaped cutting edges, the arc structure is adopted to make the cutting force smoothly transition at the corner, effectively avoid the burr and tearing defect caused by stress concentration at the sharp corner;The four side positions of the anode electrode sheet correspond to the V-shaped cutting edges, which are designed by using the progressive shearing principle, so as to implement shearing on the material in the progressive contact mode from point to line, so that the material is “cut” open instead of “torn” open, effectively reducing the generation of coating edge collapse and aluminum scrap.
