PURPOSE: A punching device of a pipe is provided to improve the quality and the reliability of a product by producing the product with more accurate standard. CONSTITUTION: A base(110) is formed by a structure with a certain height from a floor. A driving motor(120) offers driving force by installing in the upper part of the base. An operating member(130) is installed in the upper front part of the base to be reciprocated vertically by the driving motor. An operating key(140) is installed in the lower part of the base to reciprocate the operating member once by pushing. Wedge members(150) is installed in the lower sides of the operating member. A punching device(160) supports a pipe for a muffler by installing in the upper part of the base under the wedge members and punches both sides of the pipe by moving the operating member downward. Thereby, a product with a more accurate standard is produced by punching many holes through one operation.
