The invention relates to the technical field of taking and transfer devices, and discloses an automatic transfer device of a collecting pipe punching mold for taking and transferring a collecting pipe. The device comprises a base, a longitudinal moving component arranged on the base, a transverse moving component arranged on the longitudinal moving component, and multiple sets of clamping components arranged on the transverse moving component at intervals, wherein the longitudinal moving component is used for driving the transverse moving component to longitudinally slide; the transverse moving component is used for driving the clamping components to transversely slide; and the clamping components comprise baseplates, fixtures fixed on the baseplates for clamping the collecting pipe, and cylinders fixed on the baseplates for driving the fixtures to be clamped or released. The automatic transfer device of the collecting pipe punching mold is provided with the longitudinal moving component, the transverse moving component and the clamping components, realizes the automatic taking and transfer of the collecting pipe through the fit of the three parts, realizes multi-station continuous punching of the collecting pipe, improves the production efficiency of the collecting pipe punching mold, and reduces the production cost.
