Die cavity deformation molding.
Wherein, described step c is divided into preforming and precise forming two sub-steps, and the input of highly pressurised liquid is by big pressure
Valve and the connection of little pressure valve input to the swollen pressure chamber of liquid；When preforming, open big pressure valve, close little pressure valve, molding
Sheet material, to shaping mold cavity deformation, completes preforming；When precise forming, close big pressure valve, open little pressure valve the most further
The pressure increasing highly pressurised liquid reduces the flow of the swollen pressure chamber of highly pressurised liquid influent simultaneously, and sheet forming is implemented as further
Type.
The beneficial effects of the utility model are: have employed new liquid swelling forming die structure, it is possible to the liquid realizing sheet material is swollen
Molding, instead of existing stamping forming technique so that what sheet material also was able to realize opposite sex part is convenient to use this utility model
Structure realize liquid and be expanded into type, technique is simple and mould requires low, can improve the precision of molding simultaneously.It addition, press in advance
After power mould completes pretension under forcing press effect, preload pressure mould can be locked, and increase the pressure of the swollen pressure chamber of liquid,
Now can be with closing presure machine, to reduce the workload of forcing press, can effectively reduce the operating pressure of forcing press simultaneously,
Reducing and use requirement, during swollen type, floating pressure mould produces bigger pressure to the edge of sheet forming under the buoyancy of highly pressurised liquid
Clamp force realizes sealing.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
Fig. 1 is schematic diagram of the present utility model.
Detailed description of the invention
With reference to Fig. 1, New expansion forming device, including preload pressure mould 1 and floating pressure mould 2, described preload pressure mould 1
Being provided with shaping mold cavity 3, be provided with the through hole 4 adapted with shaping mold cavity 3 in the middle part of floating pressure mould 2, floating pressure mould 2 is installed on liquid
In swollen pressure chamber 5；The edge of sheet forming is compressed by the composition surface of floating pressure mould 2 with preload pressure mould 1；Preload pressure mould 1
Being connected with forcing press, liquid is swollen, and pressure chamber 5 connects highly pressurised liquid 6；During molding, forcing press drives preload pressure mould 1 and floating pressure
Mould 2 coordinates the edge of sheet forming is compressed and sealed, and liquid is swollen, and pressure chamber 5 inputs highly pressurised liquid 6, and highly pressurised liquid 6 is to pressure of floating
Power mould 2 produces buoyancy and is compacted into the edge of based plate further, and highly pressurised liquid 6 acts on sheet forming after through hole 4,
Briquetting pressure is the operating pressure * through hole area of section of highly pressurised liquid 6, makes it to preload pressure mould under the effect of briquetting pressure
The shaping mold cavity 3 deformation molding of 1.Have employed new liquid swelling forming die structure, it is possible to the liquid realizing sheet material is expanded into type, instead of
Existing stamping forming technique so that sheet material also is able to realize the structure of the present utility model that is convenient to use of opposite sex part and realizes liquid
Being expanded into type, technique is simple and mould requires low, can improve the precision of molding simultaneously.It addition, preload pressure mould 1 is at forcing press
After completing pretension under effect, preload pressure mould 1 can be locked, and increase the pressure of the swollen pressure chamber of liquid 5, now can close
Close forcing press, to reduce the workload of forcing press, can effectively reduce the operating pressure of forcing press simultaneously, reduce to use and want
Asking, during swollen type, the thrust that the edge generation of sheet forming is bigger is realized under the buoyancy of highly pressurised liquid 6 by floating pressure mould 2
Seal.
Reach the purpose of energy-saving and emission-reduction to reduce the workload of forcing press, during molding, forcing press drives preload pressure
After mould 1 coordinates with floating pressure mould 2, being locked by preload pressure mould 1, now the edge of sheet forming can rely on floating pressure completely
Power mould 2 is at buoyancy produced by highly pressurised liquid 6, and described buoyancy is the work of the operating pressure P* floating pressure mould 2 of highly pressurised liquid 6
Buoyancy area S, along with operating pressure P of highly pressurised liquid 6 incrementally increases, the buoyancy of floating pressure mould 2 also can increase therewith, molding
It is identical with buoyancy that the edge of sheet material produces bigger thrust, thus reaches good sealing effectiveness
Produced tension force during in order to ensure sealing effectiveness and the opposing molding at the edge of sheet material, floating pressure mould 2 with
The composition surface of preload pressure mould 1 is respectively equipped with projection 7 and the groove 8 for locking sheet forming edge cooperated.
In order to suitably regulate the pressure of molding and use different briquetting pressures according to different formative stages, described floating
Dynamic pressure mould 2 is provided with pressure transducer with the composition surface of preload pressure mould 1, floating pressure mould 2 detected by pressure transducer
Buoyancy, the most just can calculate the pressure of liquid swollen pressure chamber 5 mesohigh liquid 6, according to different formative stages, by adjusting
Pressure valve adjusts the pressure of highly pressurised liquid 6, it is achieved the adjustment of briquetting pressure.
The hydraulic expansion forming process of New expansion forming device, comprises the following steps that:
A. sheet forming is positioned between preload pressure mould 1 and floating pressure mould 2；
B. the edge of sheet forming is clamped in preload pressure mould 1 under the driving of forcing press and floats by preload pressure mould 1
Between pressure mould 2, the edge of sheet forming seals with floating pressure mould 2；
C. the swollen pressure chamber of liquid 5 inputs highly pressurised liquid 6, sheet forming under the effect of highly pressurised liquid 6 to preload pressure mould 1
Shaping mold cavity 3 deformation molding.
Big in view of plate forming amount during preforming, for can be good at controlling the sheet material uniform deformation of generation, therefore want
The pressure asking applying is relatively small, but during follow-up precise forming, needs the details position of shaping mold cavity 3 is realized molding, carry
The precision of high molding, needs for this to improve briquetting pressure, so step c is divided into preforming and precise forming two sub-steps,
The input of highly pressurised liquid 6 is inputted to the swollen pressure chamber of liquid 5 by big pressure valve and the connection of little pressure valve；When preforming, open big
Pressure valve, closes little pressure valve, and sheet forming, to shaping mold cavity 3 deformation, completes preforming；When precise forming, close big pressure
Power valve, open little pressure valve and further increase highly pressurised liquid 6 pressure reduce the highly pressurised liquid 6 swollen pressure chamber of influent 5 simultaneously
Flow, sheet forming realizes molding further.
