[0002] The distribution cabinet is the final equipment of the power distribution system and is a general term for the motor control center. The distribution cabinet is used in situations where the load is relatively dispersed and there are fewer circuits; the motor control center is used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. The shell material of the distribution cabinet is generally aluminum alloy. When manufacturing the distribution cabinet, holes need to be opened on the shell of the distribution cabinet according to needs for the installation of control buttons and other equipment.

[0003] For example, a punching device for a power distribution cabinet with patent publication number CN220547666U can stably press and fix stainless steel plates, and can also conveniently and quickly replace and adjust punching heads of different specifications as needed, thereby improving the use efficiency of the device.
