Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the present embodiment by asymmetric servo cylinder 1, control valve 6, high pressure Fill valve 7, switching valve 2, accumulator 11, relief valve 3,12, differential type hydraulic swing cylinder 9, selector valve 8, the primary component such as high pressure oil pump 4 and motor 5 form.Control valve 6 oil outlet is connected with the rodless cavity of single rod cylinder 1, and filler opening is connected with accumulator 11.The oil outlet of high pressure Fill valve 7 is connected with the rodless cavity of single rod cylinder 1, and filler opening is connected with high-pressure oil passage.The oil outlet of switching valve 2 is connected with the rod chamber of single rod cylinder 1, and filler opening is connected with high-pressure oil passage.In specific implementation process by control valve 6 and high pressure Fill valve 7 integrated, spool 10 is connected with differential type hydraulic swing cylinder 9, by swing cylinder 9 Direct driver.Differential type hydraulic swing cylinder 9 is connected with a selector valve 8, makes swing cylinder 9 one end normal open high pressure oil, and the other end is switched by selector valve 8 and is connected with fuel tank with high pressure oil respectively, forms differential wobble drive main control valve spool 10.
This device adopts mandatory assignment formula oil hydraulic circuit, and main control valve is that its spool 10 is by differential type hydraulic tilt cylinder 9 Direct driver by control valve 6 and the integrated high speed rotary valve of high pressure Fill valve 7.Control the folding of main control valve according to mandatory assignment Control timing sequence, oil hydraulic cylinder F.F. when low year, carries out fuel feeding as low pressure source by control valve 6 by accumulator 11, reduces system power.During heavy duty punching press, high pressure Fill valve 7 provides high pressure oil, and make the fluid in oil hydraulic cylinder 1 rodless cavity be pressurized to the pressure of high pressure fuel source, this working method reduces the flow of high-voltage oil liquid, reduce further system power.During rewind, switching valve 2 is opened to be provided high pressure oil and the fluid of oil hydraulic cylinder 1 rodless cavity is pressed into accumulator 11 energy storage by control valve 6, and unnecessary fluid through relief valve 12 oil sump tank, thus greatly reduces system power.Main control valve and switching valve are all integrated on oil hydraulic cylinder 1, further increase system responses.Control valve 6 and high pressure Fill valve 7 integrated, form main control valve valve body, driven, avoid between each control valve and occur signal delay by same spool 10, make before high pressure Fill valve 7 opens, control valve 6 shuts completely.
Swing hydraulic pressure cylinder 9 is controlled by a two-bit triplet selector valve 8, forms differential Direct driver main control valve spool 10, improves power and the response frequency of main control valve.When selector valve 8 is operated in left position, swing cylinder 9 is in differential type working state, and make the left cavity area of swing cylinder 9 be greater than right cavity area by design, then swing cylinder is to right rotation, drive main control valve spool 10 to open (or closedown) valve port, and make main control valve remain on this working state; When selector valve 8 is operated in right position, the right chamber of swing cylinder 9 connects high pressure, left chamber connected tank, then swing cylinder 9 is to anticlockwise, drives main control valve spool 10 to close (or opening) valve port, and makes main control valve remain on this working state.
Concrete: when selector valve 8 is operated in left position, swing cylinder 9 is in differential type working state, make the left cavity area of swing cylinder be greater than right cavity area by design, then swing cylinder 9 is to right rotation, drives main control valve spool 10 to turn right, main control valve is made to be operated in bottom, namely control valve 6, high pressure Fill valve 7 are operated in bottom, and switching valve 2 is operated in bottom, then accumulator 11 is communicated with oil hydraulic cylinder 1 rodless cavity, oil hydraulic cylinder 1 rodless cavity leads to fuel tank, and oil hydraulic cylinder 1 declines fast under high pressure fuel source effect.When oil hydraulic cylinder 1 contacts workpiece, selector valve 8 is operated in right position, the right chamber of swing cylinder 9 connects high pressure, left chamber connected tank, then swing cylinder 9 turns left, and drives main control core valve 10 to turn left, main control valve is operated in upper, when switching valve 2 is operated in bottom, accumulator 11 is not communicated with oil hydraulic cylinder 1 rodless cavity, and high pressure fuel source is communicated with oil hydraulic cylinder 1 rodless cavity, oil hydraulic cylinder 1, under high-voltage oil liquid effect, realizes work and enters punching press action.After punching press completes, selector valve 8 is operated in left position, swing hydraulic pressure cylinder 9, to right rotation, makes main control valve be operated in bottom, and switching valve 2 is operated in upper, accumulator 11 is communicated with oil hydraulic cylinder 1 rodless cavity, high pressure fuel source is not communicated with oil hydraulic cylinder 1 rodless cavity, and oil hydraulic cylinder 1 bottom rod chamber is communicated with high pressure fuel source, now, oil hydraulic cylinder, under high-voltage oil liquid effect, realizes rewind action.
Main control valve 6 and high pressure Fill valve 7 are in same state when oil hydraulic cylinder 1 declines and rises as shown in Figure 3, and the endurance is 40ms, and it is 20ms that pressure H enters the time.Therefore swing hydraulic pressure cylinder 9 is to right rotation, and keeps 40ms at limit position, to anticlockwise, and keeps 20ms at limit position.
