Good effect of the present utility model is: control moving of a plurality of internal changing type cylinder barrels with the plug-in mounting sequence valve; This hydraulic press function admirable, rational in infrastructure, ratio of performance to price height has improved the movement velocity and the precision of hydraulic press greatly, has prolonged service life, has reduced fault rate, the automaticity height.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the profile of plug-in mounting sequence valve of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described: a kind ofly control the hydraulic press that a plurality of internal changing type cylinder barrels move, form by plug-in mounting sequence valve, pressing plate, hydraulic cylinder with plug-in mounting Cis preface valve; Wherein link to each other with middle cylinder 9 cylinder barrel lower ends above the plug-in mounting sequence valve 8, the other end links to each other with the upper padding plate of little cylinder 11, and the valve plate of plug-in mounting sequence valve 8 is fixed by bolts on the top board 2 with middle cylinder 9; Fix 2 unsteady cylinders 5 below the lower platen 4, the spacing guide pin bushing 14 of loose core cylinder 12 and 4 location leading screws 13; The piston rod 16 in the cylinder 5 of floating passes lower platen 4 and links to each other with float plate 3, fixing feeding cylinder 17 on the float plate 3; Fix spacing feed screw nut 18 in four jiaos respectively, the lower end of leading screw 13 links to each other with lower platen 4, fix 4 vats 6, middle cylinder 9 and little cylinder 11 on the top board 2, big cylinder piston rod 10 1 ends are fixed on the lower surface of lower platen 4 by top board 2, float plate 3, lower platen 4, and the other end is fixed on the upper surface of top board 1; One end of the spacing leading screw 7 of top board 2 is connected on the top board 2, and the other end is connected 15 li of the stop nuts that are fixed on the top board 2.
When hydraulic oil entered middle cylinder 9 lower oil cavities, the cavity of resorption of four vats of this moment was communicated with epicoele and fuel tank, has realized the interior self-loopa of four vat fluid, does not work.The top board 2 big cylinder piston rods 10 that have 5 oil cylinders are moved down, and the epicoele oil of middle cylinder 9 directly enters cavity of resorption simultaneously, realizes the differential F.F. of middle cylinder 9, by the stroke of travel switch control F.F..Pressure oil continues to enter the lower oil cavitie of middle cylinder 9 during slow-motion, and the epicoele oil of the middle cylinder 9 of this moment is oil sump tank directly, has realized first pressing workpiece at a slow speed.When the oil pressure of system rises to certain pressure 16MPa (adjustable), this moment, the plug-in mounting sequence valve was opened, inserted valve is with the cavity of resorption conducting of cavity of resorption and four vats 6 of middle cylinder 9, the epicoele of four vats 6 and cavity of resorption disconnect simultaneously, make hydraulic oil enter the cavity of resorption of four vats 6, this moment, vat was worked, and the vat cavity of resorption is set up and the same high pressure of middle cylinder 9 cavity of resorptions, realize four vats 6, middle cylinder 9 five a cylinders interlock application of force, finished main suppression mission.After compacting was finished, plug-in mounting sequence valve 8 self-returns disconnected the cavity of resorption of middle cylinder 9 and the cavity of resorption of four vats 6, and the cavity of resorption of four vats is communicated with epicoele and fuel tank simultaneously.The epicoele oil-feed of middle cylinder 9, the cavity of resorption oil return has realized the backhaul of top board 1.
When oil suction chamber pressure reaches 16MPa when above, hydraulic oil by the valve of being controlled by pressure switch after, enter into plug-in mounting order (A2) valve as shown in Figure 2, valve port (A3) is opened by pressure oil, the valve piece disconnects P chamber and T chamber simultaneously, realize the conducting (wherein P1, P2 accent link to each other with the pressure cylinder cavity of resorption of press) in A accent and P1, P2 chamber, the foundation of realization high pressure.Thereby exert pressure when having realized a plurality of cylinder barrel, reach needed operating pressure.When operating mode is set when needing, the conversion of the magnetic valve by control links to each other the A2 chamber with fuel tank.Under the effect of spring force, valve port (A3) closes dead.The valve piece is communicated with (T1, T2 link to each other with the epicoele of four vats) with the P chamber with the T chamber simultaneously, realizes the pressure release of hydraulic oil from the cavity of resorption to the oil sump tank, has finished once circulation.Wherein the P1 shown in accompanying drawing three, P2 accent link to each other with the pressure cylinder cavity of resorption (9) of press by oil pipe; T1, T2 chamber link to each other with the epicoele (8) of four vats by oil pipe.
