[0002] In the metal processing industry, the punching operation of a round pipe is a common process. The round pipe is widely used in various fields, such as building, mechanical manufacturing, automobile manufacturing, etc. In these applications, a certain number of round holes are often needed to be formed on the round pipe to meet specific functional requirements, such as connection, fixation or flow, etc.
[0003] The existing round pipe needs to form three round holes. In the traditional round pipe punching operation, the round pipe is directly placed on a mounting table. A punching machine is provided with three punching heads and two supporting rods. The punching heads of the punching machine punch and drill the round pipe, and at the same time, any supporting rod is inserted into the insertion slot arranged on the mounting table to form an insertion fit, so that the round holes can be stably formed on the round pipe.
