Abstract
A method of manufacturing a battery terminal plate includes primarily pressing a single processing material corresponding to a volume body into a semi-product having an asymmetric shape through a press cutting unit; gripping the semi-product and feeding the semi-product to a first processing unit by a pickup unit; asymmetrically pressing the semi-product by a first punch to primarily forge the semi-product into a volume body part and a plate part; pressing the semi-product located in the first processing unit by a second punch to secondarily forge the semi-product while forming a detailed structure at the volume body part and the plate part; pressing the semi-product with a pressure stronger than that in the second forging step by a third punch to tertiary forge the semi-product; and punching the semi-product by a cutting/trimming unit to removing the pickup gripping member and cutting an outer peripheral portion into a final product.
