The front end of front-bank rotor housing 2 has U-shaped groove 21, and the oily runner 22 of turnover is arranged in the casing wall of front-bank rotor housing; There is the oily passage I 51 of mistake radially the front portion of throttling spacer 5, and there is oil-feed circular groove 52 at the middle part, and there is annular umbrella 53 rear end; There was oily passage II in the piston rod central authorities of supercharging composite piston 6, and the intermediate radial of piston end has annular turnover oil groove, and the turnover oil groove communicates with the oily passage II of mistake by a plurality of ducts.The front end of two-way keying valve 7 is the slide-and-guide bar, and guide rod links to each other with 45 ° of tapered sealing surfaces, and the rear end is guide cylinder, radially is processed with oil-through hole along the cylndrical surface.
The sectional area of the piston end of supercharging composite piston is 2 ~ 12.5 ︰ 1 with the ratio of the sectional area of its rod end.That is to say that maximum can be amplified to delivery pressure 12.5 times of incoming pressure.
The diameter of oil inlet hole is identical on the width of annular on supercharging composite piston turnover oil groove and the rear-bank rotor housing; The distance of the annular turnover oil groove right flank of the high order end of the throttling passage relative with oil inlet hole to the supercharging composite piston equals the length of supercharging composite piston right-hand member piston seal face, and piston seal face herein is that finger ring shape turnover oil groove right flank is to the part between the supercharging composite piston right side.
When the utility model used at hydraulic press, front-bank rotor housing was positioned at the below, and rear-bank rotor housing up.Working procedure of the present utility model is as follows:
(matched moulds) fast advances: pressure oil enters the upper end of front-bank rotor housing 2 by oil inlet hole 11 through composite pistons 6, two-way keying valve 7, and the piston 3 that pushes the work forward advances fast.At this moment form the annular space throttling between the body wall of the annular umbrella of throttling spacer 5 rear ends and rear-bank rotor housing 4, produce certain resistance, stop composite piston 6 when working piston 3 advances fast, also to be pushed ahead; Simultaneously throttling adjustable lever 8 forms throttle attenuator, and the upper end that enters composite piston 6 for hydraulic oil also produces certain resistance, can prevent effectively that also composite piston 6 from also pushing ahead when working piston 3 advances fast.Guarantee that working piston 3, composite piston 6 move according to job order.
The worker advances (moulding): after working piston 3 touches workpiece, in-cylinder pressure raises gradually, at this moment pressure oil enters the upper end of composite piston 6 through throttling adjustable lever 8, promote composite piston 6 and advance, along with the relative movement of composite piston 6 and rear-bank rotor housing 4, annular turnover oil groove and oil inlet hole 11 stagger, pressure oil can't enter the oily passage II of mistake of composite piston 6, under the pressure-acting of pressure oil, two-way keying valve 7 rises and cut out oily passage II, with working piston 3 upper end closeds.Pressure oil enters the composite piston upper end, promotes composite piston 6 and moves on, and produces the supercharging action, and piston 3 high pressure that push the work forward advance, until reach allowable pressure or Workpiece shaping.At this moment the pressure energy in the front-bank rotor housing 2 is very high, and the pressure energy in the rear-bank rotor housing 4 is lower, when stopping in rear-bank rotor housing, supplying pressure oil, pressure energy in the front-bank rotor housing 2 promotes backward little moving back of composite piston 6, because the front and back ends area difference of composite piston 6 is very large, therefore, the ultrahigh pressure pressure energy can be at the inner slowly-releasing of oil cylinder, can effectively absorb the hydraulic shock that quick return produces, the danger that reduction pipeline, cylinder body burst apart.
Return (demoulding): hydraulic oil enters the lower end of front-bank rotor housing 2 by backhaul oilhole 12 through the oil of the turnover in throttling spacers 5, front-bank rotor housing 2 walls runner 22, and piston 3 quick returns push the work forward.Because this moment, two-way keying valve 7 was in closed condition, so the fluid of working piston 3 upper ends also promotes composite piston 6 backhauls.When composite piston 6 touched back cylinder cover, two-way keying valve 7 was opened gradually, and unnecessary pressure oil is discharged, and finished the preparation of next work cycle.
