Sheet metal machining bending device capable of achieving multi-section bending and implementation method of sheet metal machining bending device

The invention discloses a sheet metal machining bending device capable of achieving multi-section bending and an implementation method of the sheet metal machining bending device, and belongs to the technical field of sheet metal machining bending devices. The metal plate machining bending device capable of achieving multi-section bending comprises an electric cabinet and a base, a U-shaped frame is fixedly arranged in the base, a clamping mechanism used for clamping a metal plate is arranged on the U-shaped frame, a first bending assembly and a second bending assembly are arranged above the U-shaped frame, and the first bending assembly and the second bending assembly are arranged on the base. The first bending assembly and the second bending assembly are fixedly arranged on the base in a staggered mode. The bending device solves the problems that an existing bending device is common in extrusion block adjusting mode, the position of the adjusted extrusion block cannot be detected, and the bending effect is
