Principle explanation（The hydraulic schematic diagram of reference picture 1）.
First, accumulator topping up is controlled：
Start Oil pump electrical machinery 17, the pressure of accumulator 2 is not up to setting value, the sender of pressure switch 8, solenoid directional control valve 12
Y1 obtains electric, and system builds pressure, and fuel pump output pressure oil is through the first check valve 6 to accumulator 2, the topping up of accumulator 2.The pressure of accumulator 2
Reach setting value, the sender of pressure switch 8, the Y1 dead electricity of solenoid directional control valve 12, system unloaded, the pressurize of accumulator 2.Wherein, may be used
The pressure oil of accumulator 2 is discharged manually by choke valve 9.
2nd, working cycles：
1st, it is servo-actuated：When under bender is slow, the first magnetic valve 7 obtains electric, and pressure oil enters Synchronization Control block.Bender is suppressed
When, the positive voltage signal of proportioning valve 16 is given, pressure oil is through proportioning valve 16（P→A）, the second magnetic valve 17 enter material carrying mechanism drive oil
The rodless cavity of cylinder 18, oil cylinder are stretched out, and material carrying mechanism support arm is tilted with sheet material is pressed.Material carrying mechanism driving oil cylinder 18 rod chamber discharge
Hydraulic oil through the second check valve 15, proportioning valve 16（B→T）Oil return box.Second magnetic valve 17 can ensure that any position of material carrying mechanism
Put locking.
2nd, retainer：When bender compacting is completed, sliding block is returned to, the second magnetic valve 17 obtains electric, gives proportioning valve 16 certain negative electricity
Signal is pressed, pressure oil is through proportioning valve 16（P→B）, pressure-reducing valve 14 enter material carrying mechanism drive the rod chamber of oil cylinder 18, oil cylinder retract,
Material carrying mechanism support arm, which is held, to be pressed sheet material and steadily falls back to workbench.The hydraulic oil of material carrying mechanism driving oil cylinder 18 cavity of resorption discharge
Second magnetic valve 17, proportioning valve 16（A→T）Oil return box.The adjustment pressure of pressure-reducing valve 14 can effectively reduce retainer impact.
