Abstract

The invention provides a punching device. The punching device comprises a machine frame, a punching portion and a conveying portion, wherein the punching portion is arranged on the machine frame, a first cutter bit and a second cutter bit are arranged on the punching portion in a spaced mode, the first cutter bit is used for punching a material into a first preset shape, the second cutter bit is used for punching the material into a second preset shape, and the second preset shape is arranged on the outer side of the first preset shape in a surrounding mode; and the conveying portion is arranged on the machine frame and enables the materials to pass through the first cutter bit and the second cutter bit in sequence. According to the technical scheme, the problem that in the prior art, aluminum foil is prone to having burrs after being punched and consequently the subsequent automatic electric core welding process is affected is solved through the punching device.

Description

technical field [0001] The invention relates to the technical field of mechanical processing equipment, in particular to a punching device. Background technique [0002] With the development of electric bus and lithium battery industry, the consistent service life and capacity density of batteries have attracted much attention. At present, the short lifespan of soft-pack batteries in the power battery industry can no longer meet the current use standards of electric buses, prompting cylindrical batteries to become the core of the current industry, and the problem of virtual welding in the welding process of cylindrical batteries after winding has been difficult to completely solve. At present, the main Use 1-2 pieces of aluminum foil as a solvent to ensure the quality of welding adhesion after cell shaping. However, the existing cylindrical battery aluminum foil punching device adopts a fixed rice-shaped punching cutter head, which requires manual tearing of the material be...
