The course of work below in conjunction with 5 pairs of the utility model of accompanying drawing 1 to accompanying drawing specifically describes, and the course of work is following:
One, press power switch on the control panel, power supply indicator is bright, and circuit is in running order; Press the electric motor starting button again, two motor 1,17 start, and the hydraulic oil of two oil pumps is through electromagnetic relief valve 6,19 low pressure off-loads; When the YA8 of electro-hydraulic reversing valve A22 gets when electric, the hydraulic oil of high pressure vane pump 16 flows to down 27 the big chamber of taking blame for others, the 27 jack-up guide rails 34 and travelling tables 32 of taking blame for others down rapidly; When travelling table is met travel switch SQ6; The YA8 outage is taken blame for others down and is changed packing state over to, moves down to prevent travelling table.
Two, get when electric as the YA6 of the YA11 of solenoid directional control valve B20 and electro-hydraulic reversing valve 21, the hydraulic oil of high pressure vane pump 16 flows to the big chamber of feeding cylinder 28, and the piston rod of feeding cylinder 28 promotes travelling table 32 reaches; Run into when moving switch S Q4 when travelling table 32, travelling table 32 moves into place, and YA6 cuts off the power supply with YA11 simultaneously; The YA10 of the YA9 of solenoid directional control valve 22 and electromagnetic relief valve 19 gets; Hydraulic oil flows to down 27 the epicoele of taking blame for others through solenoid directional control valve 22, and simultaneously with hydraulic control one-way valve 23 conductings, the hydraulic oil in 27 the big chamber of taking blame for others down flows back to fuel tank through tubular type choke valve 25 and tubular type motorized non-return valve 24; Travelling table moves down, and prepares for the worker advances processing.
Three, get electricly as the YA3 of the YA1 of electro-hydraulic reversing valve A7 and solenoid directional control valve A11, the hydraulic oil of high-pressure plunger pump 2 flows to master cylinder epicoele 37 rapidly, and master cylinder epicoele 37 forms negative pressure; Open the hydraulic control mouth of prefill valve 13 simultaneously, to master cylinder 26 fuel feeding, the sectional area of master cylinder epicoele 37 is little through auxiliary fuel tank 36 for prefill valve 13; Master cylinder 26 can be realized low thrust, high-speed action, and the piston rod of master cylinder 26 drives moving beam 33 and moves downward, when moving beam 33 touches travel switch SQ2; The SQ2 sender, it is electric to make that the YA2 of electro-hydraulic reversing valve B12 gets, and hydraulic oil gets into the big chamber 39 of master cylinder; The sectional area in the big chamber 39 of master cylinder is big; Can realize high thrust, the action of low velocity is advanced state thereby make master cylinder 26 get into the worker; When moving beam 33 bumps against travel switch SQ3; Perhaps during pressure switch 14 senders, the YA5 of electromagnetic relief valve 6 gets electricly simultaneously, and master cylinder epicoele 37 is through choke valve 10 and solenoid directional control valve A11 off-load; When the YA4 of electro-hydraulic reversing valve A7 gets when electric; The hydraulic oil of high-pressure plunger pump 2 gets into master cylinder cavity of resorption 38 fast through electromagnetism sequence valve 8, and direct-acting overflow valve 9 plays the effect of protection, and the hydraulic oil of master cylinder 26 is through prefill valve 13 quick oil returns simultaneously; Main cylinder piston-rod drives moving beam 33 and moves upward, and backhaul stops when moving beam 33 bumps against upper limit position switch SQ1.
Four, get when electric as YA8, the hydraulic oil of high pressure vane pump 16 flows to down 27 the big chamber of taking blame for others, take blame for others down 27 jack-up guide rails 34 and travelling table 32 rapidly; When travelling table 32 bumps against travel switch SQ6; YA8 outage, taking blame for others down 27 changes packing state over to, prevents that travelling table 32 from moving down.
Five, get when electric as YA7 and YA11, the hydraulic oil of high pressure vane pump 16 flows to the cavity of resorption of feeding cylinder 28 rapidly, promotes travelling table 32 backhauls; When travelling table 32 bumps against travel switch SQ5, the SQ5 sender, travelling table 32 stops; Simultaneously YA7, YA11 dead electricity, YA9 gets electric, the hydraulic oil of high pressure vane pump 16 27 the epicoele of taking blame for others of flowing through down; Shifting onto down takes blame for others 27 resets with travelling table 32, and so far, a circulation finishes.
Above-mentioned oil circuit control module also is provided with oil suction filter 3,15 and Pressure gauge 5,18; Oil suction filter 3,15 is used for removing the impurity of hydraulic oil, prevents that impurity from stopping up oil pump, and Pressure gauge 5,18 is used to observe the pressure of hydraulic oil; Work time, the scope that oil pressure must not overshoot; Because moving beam 32 is provided with the Cheng KaiguanS Q3 that restricts driving; Moving beam 32 is after touching SQ3, and SQ3 can send the backhaul signal, therefore; The difference of SQ3 position has determined the difference of moving beam 32 strokes, thereby realizes deciding process control through lower bound range switch S Q3; In addition, the utility model is provided with a pressure switch 14, and when the descending pressure of master cylinder reached the preset value of pressure switch 14, moving beam 32 just stopped descending, and after the pressure release, moving beam rises automatically, realizes level pressure control with this; Promising three beams of the utility model four root architectures; Its guidance quality is good, good rigidly, superior performance; Be applicable to various corrections, press-fit, product technology such as punching, embossing, cut-out, sulfuration, cold extrusion, in addition, main hydraulic of the utility model and seal all adopt the product of world famous brand company; Superior performance, reliable in quality.
Announcement and instruction according to above-mentioned specification; The utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment; Therefore; The specific embodiment that discloses and describe above the utility model is not limited to is in the protection domain of the claim that also should fall into the utility model to some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
