PURPOSE: A manufacturing apparatus of exhaust pipe for microwave oven is provided to lower facility cost of the microwave oven exhaust pipe manufacturing, thereby lower manufacturing cost of the exhaust pipe accordingly by manufacturing the exhaust pipe of the microwave oven through one cycle operation. CONSTITUTION: The manufacturing apparatus of exhaust pipe for microwave oven comprises a cutting part for cutting a rod shaped metal rod material(20) that is a base material for the exhaust pipe of the microwave oven to a set sized piece shape; a plurality of fingers(12) for moving the base material step by step from one side to the other side after catching the piece shaped base material cut by the cutting part; a die comprising a plurality of receiving grooves which are arranged at position where the fingers are stopped, and in which an ejector is installed, and the piece shaped base material is housed; a transfer unit arranged at the other side of the die to operate the fingers repeatedly from one side to the other side; and a punching part(16) arranged at the rear side corresponding to the die to hit the base material inserted into the receiving grooves, wherein the die further comprises second receiving grooves(40) installed at the other side of the die opposite to one side of the die from which the metal rod material is drawn out so that a piece shaped base material on which hole is penetratingly formed in a vertical central line direction from one side to the other side of the receiving grooves is housed in the second receiving grooves, and the apparatus further comprises a press(50) integrally installed at the other side of the punching part corresponding to the second receiving grooves to manufacture the exhaust pipe by hitting the piece shaped base material housed in the second receiving grooves.
