Wherein, the turntable can be driven to rotate by a servo motor; the number of the punches 4 may be plural, specifically, six, or eight. Of course other numbers are possible; the pipe fitting can be a copper pipe or other pipe fittings.

Through the structural arrangement, at least two punches are arranged on the turntable along the rotation direction of the turntable, and specifically, the two punches can be different. When the pipe fitting punching and shaping device is used, the required punch is conveyed to the punch station through the turntable, and the end part of the pipe fitting on the clamping station can be punched and shaped by the punch. When different punches need to be used, the corresponding punches can be switched to the punching station through the rotation of the turntable, so that the punches can shape and punch the end part of the pipe fitting on the clamping station.
