The invention provides machining equipment for a three-way copper pipe fitting and belongs to the technical field of automatic processing equipment. The machining equipment comprises a feeding mechanism, a punching mechanism, a flaring mechanism, a shaping mechanism and an end flatting mechanism which are arranged on a workbench and sequentially arranged in the same direction, wherein a transportmechanism is arranged perpendicular to the workbench, and all the mechanisms are connected in series through the transport mechanism. As the punching mechanism, the flaring mechanism, the shaping mechanism and the end flatting mechanism are arranged on the same workbench, and the mechanisms are connected through the transport mechanism, the machining process, including, punching, spin-flaring, shaping and end flatting, of the three-way copper pipe fitting, is finished on the same equipment, and the working efficiency is improved; the punching mode replaces a head cutting mode, so that the yield is improved, and material waste is avoided; and meanwhile, as a program controller is arranged, automatic control is achieved, the labor intensity of staff is reduced, and the production security isimproved.
