What is CNC press brake and it’s working principle

CNC press brake is used to complete the bending of sheet metal. The back stop positioning system, the bending depth of the ram and the automatic compensation of the worktable deformation are controlled by the CNC system.

It provides a variety of operation modes.

Under three different working conditions such as no-load speed, working speed and return speed, it can always maintain the position synchronous speed of the ram (parallel to the workbench) and achieve high-precision positioning at the end of the stroke.

It is widely used in automobiles, shipbuilding, containers, cranes, engineering machinery, building institutions, metal structures, lamp poles bending of super long components in power pole and other industries.

The CNC press brake is composed of frame, ram, worktable, oil cylinder, hydraulic proportional servo system, position detection system, CNC system and electrical system.

When the operator steps on the foot switch on the operating station, the ram moves rapidly from the top dead center to the speed change point at no-load speed under the control of the numerical control system and hydraulic servo system (also known as the safety braking point, which refers to the conversion point between the no-load speed and working speed of the ram, and its position can be adjusted), and then the ram continues to move downward at the working speed.

When the ram moves to the bottom dead center (also known as the end of the stroke, whose position can be adjusted), the positioning of the end of stroke is completed and the pressure is maintained through the hydraulic servo system. At this time, the plate clamped between the punch and die forms a required angle, and then the ram quickly returns to the top dead center.
