Pipe end zinc flowing hole stamping equipment

Pipe end zinc flow hole stamping equipment comprises a machine base, and a guide rail and a driving air cylinder are arranged on the machine base. Stamping units are slidably mounted on the guide rails, machining openings are formed in the inner sides of the two stamping units, limiting seats are mounted on the inner sides of the two stamping units, and the two machining openings are oppositely formed and located on the same axis in the left-right direction; the two limiting seats are provided with limiting grooves; the two driving air cylinders are in driving connection with the corresponding punching units correspondingly. According to the embodiment of the utility model, the two punching units are arranged, and the limiting seats with the limiting grooves are mounted on the punching units, so that the two punching units can move oppositely under the driving of the driving cylinder only by placing the two ends of the pipe fitting into the corresponding limiting grooves; the two ends of the pipe fitting are
