DIE APPARATUS FOR MANUFACTURING SECONDARY BATTERY AND LINK-TYPE KNOCKOUT UNIT FOR DIE APPARATUS

Abstract

The present disclosure relates to a die apparatus for manufacturing a secondary battery and a link-type knockout unit for the die apparatus. The die apparatus for manufacturing a secondary battery includes a lower die that supports an electrode plate and has one or more scrap discharge holes, an upper die positioned above the lower die and including a punch corresponding to each of the scrap discharge holes, and a knockout unit including a pad vertically moving inside the scrap discharge hole and a pad support that supports the pad upward and allows the pad to apply a reaction force corresponding to a downward pressure of the punch to a bottom surface of the electrode plate when the punch moves downward.
