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.
Introduction of each axis of press brake
Y upward – downward of cylinder
Y1 upward – downward of left cylinder
Y2 upward – downward of right cylinder
X forward – backward of back gauge
X1 forward – backward of left finger on back gauge
X2 forward – backward of right finger on back gauge
R upward – downward of back gauge
R1 upward – downward of left finger on back gauge
R2 upward – downward of right finger on back gauge
Z leftward – rightward of back gauge
Z1 leftward – rightward of left finger on back gauge
Z2 leftward – rightward of right finger on back gauge
W mechanical crowning of worktable
V hydraulic crowning of worktable
