PURPOSE: A punching apparatus for increasing the durability of a punching blade by preventing damage to a punching blade in a punching step is provided to prevent the breakage of a punching blade by contacting the center axis of a punching blade on the surface of a material. CONSTITUTION: A punching apparatus comprises first and second base members(10,20), a punching blade member(30), a first and second ascending and descending guide members(40,60) and a punching blade guide member(50). The first base member has a material settling part(11) on the top. The punching blade member is projected from the lower surface of a second base member. The material settling part punches a hole on a material which is settled on the material settling part. The first ascending and descending guide member connects the first and second base members in order to up and down move the first and second base member. The punching blade member passes through a guide hole(51) of the punching blade guide member. |
