In order to solve the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of books indent hydraulic pressure installation; It is characterized in that: comprise first oil hydraulic pump 6, second oil hydraulic pump 5; Three position four-way directional control valve 17; Three position four-way directional control valve 18.1 and indent oil cylinder 21; Said first oil hydraulic pump 6 is connected to first hydraulic fluid port of three position four-way directional control valve 17, and second oil hydraulic pump 5 is connected to second hydraulic fluid port of three position four-way directional control valve 17 and first hydraulic fluid port of three position four-way directional control valve 18.1, and the 3rd hydraulic fluid port of three position four-way directional control valve 17 is connected to first hydraulic fluid port of three position four-way directional control valve 18.1; The 3rd hydraulic fluid port of said three position four-way directional control valve 18.1 and the 4th hydraulic fluid port are connected the upper end hydraulic fluid port and the lower end hydraulic fluid port of indent oil cylinder 21 respectively, and second hydraulic fluid port of said three position four-way directional control valve 18.1 is connected to fuel tank.
Said second oil hydraulic pump 6 is connected to first hydraulic fluid port of three position four-way directional control valve 18.1 through one-way valve 14.2, and the 3rd hydraulic fluid port of said three position four-way directional control valve 17 also is connected to first hydraulic fluid port of three position four-way directional control valve 18.1 through reduction valve 16.
Adopt technique scheme, the present invention has only just realized comprising Shi Xiaoli and the indent action of executing energetically through two oil hydraulic pumps and two three position four-way directional control valves, have simple in structure, the advantage of reliable in action.
Description of drawings
Be elaborated below in conjunction with accompanying drawing and embodiment the present invention:
Fig. 1 is a hydraulic scheme of the present invention.
Embodiment
As shown in Figure 1, books indent hydraulic pressure installation of the present invention comprises first oil hydraulic pump 6, second oil hydraulic pump 5, connects a three position four-way directional control valve 17,18.1, indent oil cylinder 21.
Wherein, first oil hydraulic pump 6 and second oil hydraulic pump 5 are positioned on the duplex pump, are driven by motor 4; First oil hydraulic pump 6 is metering pumps; Second oil hydraulic pump 5 is variable displacement pumps, and first oil hydraulic pump 6 provides the oil pressure of 80bar for system, and second oil hydraulic pump 5 provides the oil pressure of 30bar for system.
Two three position four-way directional control valves 17,18.1 all have two spool a, b and four hydraulic fluid ports, when promoting spool a to valve pocket, realize that first hydraulic fluid port and the 4th hydraulic fluid port connect, second hydraulic fluid port and the perforation of the 3rd hydraulic fluid port; When promoting spool b when valve pocket is opened, realize the perforation of first hydraulic fluid port and the 3rd hydraulic fluid port, second hydraulic fluid port and the perforation of the 4th hydraulic fluid port.
First oil hydraulic pump 6 connects the forward hydraulic fluid port of one-way valve 10 (one-way valve has positive and negative two hydraulic fluid ports, and oil flows to from the forward hydraulic fluid port can pass through one-way valve, flows to then from reverse hydraulic fluid port and can not pass through one-way valve).The reverse hydraulic fluid port of one-way valve 10, accumulator 11, relief valve 9 (relief valve has filler opening and oil outlet, when the oil pressure of filler opening less than setting value, then can not pass through relief valve; When the oil pressure of filler opening surpasses setting value, the part that surpasses can be fallen through the relief valve overflow) filler opening and first hydraulic fluid port of three position four-way directional control valve 17 link together.
Second oil hydraulic pump 5 connects the forward hydraulic fluid port of one-way valve 7.Second hydraulic fluid port of the oil outlet of the reverse hydraulic fluid port of one-way valve 7, accumulator 8, relief valve 9, the filler opening of relief valve 13, three position four-way directional control valve 17, the forward hydraulic fluid port of one-way valve 14.2, the forward hydraulic fluid port of one-way valve 14.3 link together.The oil outlet of relief valve 13 is connected to fuel tank 23.
The reverse hydraulic fluid port of the 3rd hydraulic fluid port of three position four-way directional control valve 17, the filler opening of reduction valve 16, one-way valve 15 links together.First hydraulic fluid port of the reverse hydraulic fluid port of one-way valve 14.2, the oil outlet of reduction valve 16, pressure gauge 19.1 and three position four-way directional control valve 18.1 links together.The 3rd hydraulic fluid port of three position four-way directional control valve 18.1 and the 4th hydraulic fluid port are connected to the upper end hydraulic fluid port and the lower end hydraulic fluid port of indent oil cylinder 21 respectively through one-way throttle valve 20.1,20.2.
And pressure gauge 19.2 is connected to the reverse hydraulic fluid port of one-way valve 14.3.Three position four-way directional control valve 18.1 second hydraulic fluid ports are connected to fuel tank 23 through oil purifier 1.
More than be exactly books indent hydraulic pressure installation of the present invention, wherein first oil hydraulic pump 6 produces the 80bar oil pressure, and second oil hydraulic pump 5 produces the 30bar oil pressure.The working method of this device is following:
Before the spool b of three position four-way directional control valve 17 does not shift valve pocket onto; The spool a of three position four-way directional control valve 18.1 is shifted onto in the valve pocket; At this moment the lower end hydraulic fluid port that the hydraulic oil of the 30bar that is produced by second oil pump 5 gets into indent oil cylinder 21 through first hydraulic fluid port and the 4th hydraulic fluid port of one-way valve 14.2, three position four-way directional control valve 18.1; Be indent oil cylinder 21 by closed condition to open mode, drive the surface of push type broach to book cover.
Arrive the surface of book cover when push type broach after; The spool b that switches three position four-way directional control valve 17 is to valve pocket; Make first hydraulic fluid port and the 3rd hydraulic fluid port of three position four-way directional control valve 17 be communicated with, the hydraulic oil of the 80bar that at this moment flows out from the 3rd hydraulic fluid port of three position four-way directional control valve 17 is through reduction valve 16, and first hydraulic fluid port of three position four-way directional control valve 18.1, the 4th hydraulic fluid port flow in the indent oil cylinder 21; To push type broach big pressure is provided, thereby accomplishes the indent action.
After indent was accomplished, the spool b that promotes three position four-way directional control valve 18.1 again was to valve pocket, indent oil cylinder 21 reset conditions of withdrawing.Subsequently, the spool of three position four-way directional control valve 18.1 is to meta, and the spool of three position four-way directional control valve 17 all returns reset condition to meta.
So just accomplished the whole little power of executing earlier, after execute indent action energetically.
Therefore,, can find out that the present invention has only just realized comprising Shi Xiaoli and the indent action of executing energetically through two oil hydraulic pumps and two three position four-way directional control valves through above-mentioned detailed description, have simple in structure, the advantage of reliable in action.
But; Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the present invention; And be not to be used as qualification of the present invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention the above embodiment's variation, modification.
