Metal product machining device

The invention discloses a metal product machining device. The device comprises a machining platform, vertical supporting columns are arranged on the two sides of the machining platform, a power mechanism is arranged at the tops of the supporting columns, machining equipment is arranged at the bottom of the power mechanism, and the power mechanism is used for controlling the machining equipment to move vertically. An energy storage device is arranged on the side face of the machining platform, the energy storage device is used for converting gravitational potential energy generated in the downward moving process of the machining equipment into electric energy and storing the electric energy, and an adjusting supporting mechanism is further arranged on the side face of the machining device. Through vertical reactive force of the energy storage device for the machining equipment, the energy consumption of the power mechanism for overcoming the gravity of the machining equipment is reduced, the gravitational pote
