Notching mold with increased notching efficiency for secondary battery electrode and notching mold manufacturing method

摘要

An object of the present invention is to provide a notching mold having improved notching efficiency of a secondary battery electrode plate. The configuration of the present invention comprises: a lower mold 20 disposed on a transfer line of the electrode plate 2; An upper mold 30 that is elevated from above the lower mold 20; A punch hole provided in the lower mold 20; A punch receiving hole provided in the upper mold 30; A punch that is accommodated in the punch receiving hole and enters the punch hole when the upper mold 30 descends to the lower mold 20; An adjustment spacer inserted between the punch receiving hole and the punch to adjust the clearance of the punch; It characterized in that it comprises; and a tension bolt (60) that is coupled to the upper mold (30) to support the adjustment spacer and to secure a notching gap (SPC) of the punch during the notching of the electrode plate.
