Metal processing machine tool with automatic feeding structure

The invention relates to the technical field of metal processing machine tools, and provides a metal processing machine tool with an automatic feeding structure, which comprises a machine tool shell, a base and fixed air cylinders, fixed supporting plates are symmetrically mounted on one side of the top end of the base, and second driving air cylinders are mounted at the two ends of the fixed supporting plates; and a feeding mechanism is arranged on the other side of the top end of the base, and a machine tool shell is installed at the top end of the base. The fan is arranged at the top end of the machine tool shell, chippings in the machine tool shell can be sucked into the dust collection box through the dust suction pipe by starting the fan, the purpose of removing the chippings is achieved, the chippings are prevented from influencing the machining efficiency, the dust collection box is pulled and pulled out from the interior of the protective shell, the purpose of cleaning the dust collection box is achi
