PURPOSE: An O-ring punching apparatus is provided to maximize the punching efficiency by separating interior and exterior burr at a time. CONSTITUTION: An O-ring punching apparatus(110) comprises top and bottom punches(112,113), a product box(114), a burr box(115), a product hopper(116), and a burr hopper(117). The top punch punches an O-ring and interior burr by moving up and down. The bottom punch is installed under the top punch on the top of a frame(111) and removes the O-ring, the interior burr, and the exterior burr by moving to and from the bottom punch. The product box and the burr box collect punched O-rings and interior burr. The product hopper and the burr hopper discharge punched O-rings and interior burr to the product box and the burr box.
