Blanking unit and manufacturing apparatus for laminated core having the same

摘要

The present invention provides a blanking unit and an apparatus for manufacturing a laminated core having the same. The blanking unit manufactures a laminated member by blanking a metal strip by inserting a blanking punch to be installed on an upper die into a rotation die on a lower die by descending the upper die. The present invention includes; a rotation unit which rotates the rotation die at a specific angle during a rotation period and stops the rotation die during a stop period; and a pressurizing unit which is installed on the lower die, pressurizes the rotation die by adhering to the rotation die during a pressurizing period by proceeding toward the rotation die if the stop period starts, and releases the adhesion to the rotation die by retreating to the opposite to the rotation die before the rotation period starts if the pressurizing period passes. The present invention prevents the laminated member from being shaken after rotation die is stopped when the laminated member is laminated by index or skew.
