Hardware stamping metal machining device

The invention discloses a machining device for hardware stamping metal, and relates to the technical field of stamping. The hardware stamping metal machining device comprises an equipment main body, a driving assembly, a stamping head and a pipe fitting fixing seat, the driving assembly is fixedly installed on the equipment main body, the stamping head is fixedly installed on the driving assembly, the pipe fitting fixing seat is fixedly installed on the equipment main body, and a pipe fitting is placed on the pipe fitting fixing seat; the driving assembly drives the stamping head to ascend and descend to conduct stamping machining on the pipe fitting, the stamping head can generate a large amount of heat in the long-time machining process, so that the machining efficiency of the stamping head is affected, when the temperature of the stamping head rises, the thermal expansion blocks collide, the circulation opening is opened, and cooling liquid in the heat dissipation box flows out to conduct automatic heat di
