The drawbacks of carrying out drawing using rigid mould for existing rocket fuel reserve tank part, this patent provides one kind and is used for
The liquid-filling shaping technique of rocket fuel reserve tank part, comprising the following steps:
S1, liquid-filling shaping mold and press are attached；
As shown in Figure 1, the liquid-filling shaping mold includes punch-pin 1, cavity plate 2 and blank holder 3；As shown in Fig. 2, the press
It is a double action press, is set on press there are two movable mechanism, the movable mechanism is respectively drawing sliding block 9 and flanging
Sliding block 10；Press of the invention is the double acting press of Back Word type, and 9 sets of the drawing sliding block is in blankholder slide 10；
The specific connection method of liquid-filling shaping mold and press are as follows:
1) convex mould base 6 is connect with drawing sliding block 9 using T-type screw；
2) die socket 7 is connect with workbench using T-type screw；
3) flanging ring support 8 is connect with blankholder slide 10 using T-type screw；
4) the filling liquid interface 11-1 of hydromechanical system 11 is connect with cavity plate 2 using hose；Liquid in the hydromechanical system 11
Pressure system is used to control fluid pressure in mold and store liquid power transmission medium)；
S2, the blank holder 3 and the punch-pin 1 move straight up, open liquid-filling shaping mold；
S3, blank 4 to be processed are placed in 2 upper surface of cavity plate, and blank 4 is vertical circumferentially to be positioned using blank positioning plate 5,
Prevent blank 4 from generating the displacement of horizontal direction；
2 internal cavity of cavity plate is filled up liquid power transmission medium by filling liquid interface 11-1 by S4, liquid-filling shaping system；
Preferably, liquid power transmission medium is the emulsion for having the functions such as lubrication, antirust, deodorization；
S5,10 downlink of blankholder slide drive 3 downlink of blank holder, and blank 4 is pressed on cavity plate 2 by blank holder 3；
S6, blank holder 3 are pressurized to pressure needed for given process；
S7, drawing sliding block 9 drive 1 downlink of punch-pin, and it is intracavitary that blank 4 is headed into 2 type of cavity plate by punch-pin 1；Since 1 downlink of punch-pin is squeezed
The closed containing cavity that green compact material 4 and cavity plate 2 are formed, the intracavitary liquid power transmission medium of 2 type of cavity plate is rejected to through filling liquid interface 11-1 to be filled
Liquid formation system；Hydromechanical system 11 is adjusted according to the pressure curve calculated at this time, the pressure for keeping type intracavitary meets setting pressure；
During 1 downlink of punch-pin, fluid pressure will make blank 4 constantly paste cavity plate 2, and the liquid chamber pressure of variation makes base
Material 4 is evenly distributed on punch-pin 1；
S8, drawing on earth after, liquid chamber release synchronous with punch-pin 1；,
Liquid chamber release synchronous with punch-pin 1 is because part is after forming simultaneously by 1 pressure of liquid chamber pressure and punch-pin；This two
A pressure acts on part simultaneously, and reaches a balance at the eleventh hour.Liquid chamber pressure, 1 pressure of punch-pin are first unloaded at this time
Greater than liquid chamber pressure, punch-pin 1 will continue to downlink drawing；If first unloading 1 drawing pressure of punch-pin, liquid chamber pressure can jack up punch-pin 1, very
Extremely by damage parts.So no matter first unloading which pressure can all cause damage parts, therefore synchronize unloading.Liquid chamber pressure pass through by
Valve port gradually opens release；1 pressure of punch-pin is reduced by reducing press tonnage；
S9, the drawing sliding block 9 drive the punch-pin 1 to lift, and then blankholder slide 10 drives blank holder 3 to lift；
After S10, blank holder 3 lift, it is intracavitary that part is stuck in 2 type of cavity plate, and part blocks since side wall is sprung back with cavity plate 2

Blank holder 3 pushes down plate and forms confined space inside cavity plate 2 during 1 downlink drawing parts, can make zero in internal filled liquid pressurization
Part pastes punch-pin 1 under the action of hydraulic.
Compared to common die, cavity plate 2 deviates forming for the thick shape face of material by punch-pin 1.During the cavity plate 2 of this technique is then
Empty, the intracavitary portion of type is filled up by liquid power transmission medium.Different anti-inflation effects is generated according to pressure change, gradually pastes plate
Cover punch-pin 1.Compared to the common cavity plate 2 being made of mold rigid body, cavity plate 2 of the invention is made of liquid chamber, and liquid chamber increase is not
With pressure after can make blank 4 it is anti-inflation go out different shape paste punch-pin 1, become a transformable flexible media cavity plate 2.
3 resistance problem of blank holder is concentrated on merely compared to conventional ones critical technological point, this part punching moulding process is crucial
It is the matching of 1 stroke of liquid chamber pressure and punch-pin, different 1 positions of punch-pin needs different liquid chamber pressures.It is hydraulic excessive easy
Cause ridging defect, it is hydraulic too small to be easy to cause cracking defect, it is therefore desirable to reasonable hydraulic pressure curve when formulating part forming；
Technical study initial stage enters the relevant parameter of rocket fuel reserve tank part in Dynaform finite element numerical simulation software, to part at
Liquid chamber increasing pressure curve during shape has carried out finite element analysis, proof of analog result feasible process.
The calculation method of relevant parameter is as follows in the present invention:
FDrawing=FDeformation+FIt is hydraulic
Wherein,
FDrawingPressure needed for drawing sliding block 9, T when-molding；
FDeformationThe resistance of deformation that the deformation of-material generates, T；FDeformation=k × L × t × σb
Wherein:
K-coefficient (is determined) by drawing coefficient, about between 0.4~1
The length on 4 deformed cross sections periphery of L-blank, mm；
4 thickness of t-blank, mm；
σb4 tensile strength of-blank, MPa；
FIt is hydraulic- drawing sliding block 9 resists the hydraulic opposition of liquid chamber；FIt is hydraulic=PLiquid×S
Wherein: PLiquid- liquid chamber pressure, MPa；
S-liquid and 4 contact area of blank, mm2。
To guarantee reasonable hydraulic pressure curve, emulated by Dynaform finite element numerical simulation software, it is reasonable to determine
Liquid chamber increasing pressure curve；And in practical die trial, the pressure anomaly loss that is generated for " flooded lubrication " and " building the pressure " phenomenon and
Exception, which increases, targetedly to be compensated, and guarantees the consistency of the hydraulic hydraulic pressure curve gone out with finite element modelling in actual mould.
Flooded lubrication: refer to part blank holder 3 by cavity plate 2 liquid power transmission medium jack up after, liquid power transmission medium along
Gap discharge, causes liquid room pressure to reduce phenomenon extremely.
Build the pressure: 1 downlink of drawing punch-pin when building the pressure, liquid power transmission medium can not be discharged in time in cavity plate 2, will cause liquid chamber power
Pressure anomaly increases phenomenon.
Flooded lubrication and the phenomenon that builds the pressure can even occur simultaneously sometimes, it is difficult to be compensated completely by calculating, need reality
Border is debugged, and pressure curve is adjusted in debugging process.
Through examining, the manufacturing method of the present invention forming accuracy is high, stability is good, can satisfy requirement, and save at
Originally, the surface quality that can be improved part production efficiency and part, has entered the volume production stage.
