角柱状バッテリセル容器を生産するための方法及び装置
Document Type and Number:
Japanese Patent JP6780104
Kind Code:
B2
Abstract:
The invention refers to a method and an apparatus (20) for manufacturing of a prismatic unilaterally open battery cell container (21). First an extruded container (41) is formed from a slug (38) by extrusion. The slug (38) consists of a uniform material. The extruded container (41) is then formed by a first ironing in a first ironing station (25) and by a second ironing in a second ironing station (28). During ironing the container is moved by a respective ironing ram (26, 29) only partly through an associated die tool (27, 30) and is reversed when reaching a reversal point (U). After the second ironing a remaining edge (82) of the obtained intermediate container (77) is separated, thereby the battery cell container (21) is obtained.
