The synchronization of the press brake adopts the technology of full loop electro hydraulic servo control, the positioning signal of the ram is feed back by optical encoder to the CNC system, which controls the opening size of the synchronizing valves and adjusts the oil inlet amount of the oil cylinders, to realize the synchronizing movements of the ram ( Y1, Y2), and keep the worktable always in parallel situation.
