Problems solved by technology

The traditional die-cutting knife die completes the production of pole pieces through the coordinated cooperation of the die-cutting machine or the punching machine and the movement of the base material. There will be gaps between the pole pieces, and the raw materials of the pole pieces are seriously wasted in the production process.

Abstract

The invention provides a lithium battery pole piece punching cutter die which comprises a die plate base and punching cutter sets perpendicularly arranged on the die plate base and used for punching lithium battery pole pieces. Each punching cutter set comprises a pole lug-top edge punching cutter, a bottom straight edge punching cutter and a lateral edge punching cutter. Each pole lug-top edge punching cutter comprises a right top chamfering punching cutter body, a left top chamfering punching cutter body, a left top straight edge punching cutter body, a pole lug punching cutter body and a right top straight edge punching cutter body, wherein the left top straight edge punching cutter body and the right top straight edge punching cutter body are parallel to the corresponding bottom straight edge punching cutter, the left top straight edge punching cutter body, the right top straight edge punching cutter body and the corresponding bottom straight edge punching cutter are all perpendicular to the corresponding lateral edge punching cutter. By means of the punching cutter die, continuous punching can be achieved, gaps between punched pole pieces do not exist, gap waste cannot be generated, and therefore the utilization rate of raw materials is increased, and the pole piece material cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of punching equipment, and in particular relates to a lithium battery pole piece punching knife die. Background technique [0002] At present, in the production process of lithium batteries, the production of battery pole pieces is generally carried out by continuous die-cutting machine or punching machine, and the pre-designed knife die is used for punching to obtain the pole pieces of the desired size and shape. piece. The traditional punching dies complete the production of pole pieces through the coordination of die-cutting machine or punching machine jumping and substrate movement. There will be gaps between pole pieces, and the raw materials of pole pieces are seriously wasted in the production process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lithium battery pole piece punching knife die for the above-mentioned deficiencies in th...
