摘要

A circle-pressing-circle die-cutting device for battery pole piece includes a die roller and a cutter die roller that are parallel to each other, where a proper gap is provided between the rollers. A cutter die line to cut pole piece is provided on the surface of the cutter die roller. A mat is provided between the die roller and the cutter die roller, and the battery pole piece lies between the mat and the cutter die line. Rigidity of the mat is less than that of the battery pole piece. The device additionally includes a driving system whose power is coupled to the die roller and cutter die roller to drive the die roller and the cutter die roller to rotate synchronously. The circle-pressing-circle die-cutting device is well adapted for die cutting metal and improves work efficiency and processing quality.
