Numerical control bending machine convenient for angle adjustment

The invention relates to the technical field of bending machines, in particular to a numerical control bending machine convenient for angle adjustment. The numerical control bending machine is characterized in that a feeding slot is fixedly formed in the upper surface of a workbench; the left end and the right end of the feeding slot are opened; a bending supporting seat is rotationally arranged on the portion, located at the right side of the feeding slot, of the upper surface of the workbench through a rotating shaft; a bending arm is rotationally arranged on the portion, located at the right side of the feeding slot, of the workbench through a rotating shaft; the bending arm and the bending supporting seat are coaxially arranged; a driving component is fixedly arranged on the workbench; the output end of the driving component is connected with a bending arm; and an angle adjusting component is fixedly arranged on the bending arm. According to the numerical control bending machine, an arc-shaped driving con
