Third, the filling means filling device is mounted on the upper end of the master cylinder, which consists of filling the tank fill valve and components. When the master cylinder piston down quickly, the master cylinder on a negative pressure chamber, open the valve filling valve, filling the master cylinder chamber, the lower chamber of the master cylinder fluid pushes the return of the main spool, the oil chamber of the master cylinder back into the tank filled with back hole on filling the fuel tank, filling the tank oil level control. The excess oil back into the main tank to prevent the oil spill from the tank filled. Upper and lower travel limit control device controls the right side of the upper and lower travel limit device is installed on the host, the frame, hit the block, limit switches and other components. Bracket on the right side of the beam with the table, hit the block is fixed to the slider to the right side, the trip switch fixed on the bracket, adjust the position of the limit switch can control the operation of the position of the slider. Fourth, the hydraulic system overview (a) Overview of the hydraulic system consists of energy conversion devices (pumps and cylinders), the energy adjustment device (various valves) and energy delivery devices (fuel tank, filling tube, piping) and other components. With control of the electrical system of beam-driven activities, completion of all the action cycle. This machine has two ways to adjust and semi-automatic choice. Adjustment method is relatively simple hand movements required to press a button to get the appropriate action to stop immediately let go. Semi-automatic operation for pressing the button to make the work activities to complete a process of automatic beam movement cycle. (B) a description of the hydraulic principle, power, start the motor, the solenoid valve is in the neutral position, the pump unloading. 2, the slider down quickly: YV1, YV3, YV4 electricity can achieve rapid downward slide action, YV1 pass one, power, start the motor, the solenoid valve is in the neutral position, the pump unloading. 2, the slider down quickly: YV1, YV3, YV4 electricity can achieve rapid downward slide action, YV1 powered, plug-C1 closed, pump outlet and cut back to the oil port, system boost, YV4 energized so that the plug-C2 open systems the master cylinder pressure oil into the upper chamber, YV3 electricity, so the plug-C3 open, the lower chamber of the master cylinder oil quickly drain back to the tank, relying on weight fast downward slide. 3, the slider slow repression: When the slider touches the limit switch, YV3 lost power, while YV2 energized, the pressure in a chamber under the cover of the regulator valve F17 it is set, and thus the lower chamber drain slow down, slow slide into downward, and the pressure contact with the workpiece. 4, packing: slide the working stroke is completed, touch the lower limit switch, the slider return complete suppression relief action, or in-cylinder pressure increases, when it is set by Paul rolling relay, complete constant pressure suppression action. 5. relief: lower limit switch sender or sender breaker delay, into relief, this time YV1, YV2, YV5 powered pump into the work, YV5 energized solenoid valve P and B ports through open start filling valve relief. A and O port through, so the plug C4 is on, the system pressure oil into the master cylinder lower chamber, YV2 energized, the lower chamber of the pressure valve F17 was given a low pressure regulator cover tune, and this can only be opened given pressure adjustment charge valve, rather than make the slider return, thus avoiding the impact of high pressure relief. 6, slider return: the upper chamber when the pressure of the master cylinder after unloading to zero, YV2 loss of power, from the delay breaker controlled so that the pressure-transducing chamber under the cover by the regulator valve F16 it is set in the return pressure, return the slider. When exposed to the slider limit switch, solenoid valve energized, the slider stops. Thus, to achieve a pressing, the top of the action. V.
