Description
Technical field
The present invention relates to machine-building hydraulic expanding die technical field, more particularly to one kind to be used to manufacture S type metal waves
The detachable hydraulic expanding die of line pipe.
Background technology
S types bellows is due to having the advantages that excellent voltage endurance capability, compensation ability, anti-fatigue performance and high life, extensively
It is general to apply in the pipe-line system of the industries such as aerospace, petrochemical industry, electric power.But S types bellows is due to its complicated ripple
Tee section feature make it that its Plastic Forming is very difficult.The forming mode of S type bellowss has two kinds：U-shaped ripple secondary extrusion method (poplar
Gorgeous virtue, Jiang Yangang, what continues the making China New Products .2013,11 of river .S shape metal bellows:And molten modulus method 25)
(Huang is that peaceful specialty metals bellows develops Shenyang:Shenyang University of Technology's Master's thesis, 2003).In U-shaped ripple secondary extrusion method
In, cylinder material is fitted into hydraulic forming mold first, pressure is radially applied to cylinder material, a material is configured to cross section as one
Or the bellows of several continuous Us, then apply axial compressive force to U-shaped bellows, deform at the trough fillet of cross section,
It is recessed S type ripples.After applying axial force, the material deformation everywhere of U-shaped cross section is uneven, especially wave crest and trough
Radius of corner deviation is larger, and each U-shaped cross-sectional deformation amount is also inconsistent, the S type bellowss cross section ruler obtained in this way
It is very little to be difficult to accurately ensure, influence working life.Compared to U-shaped ripple secondary extrusion method, when manufacturing S type bellowss using molten modulus method,
A material is set to be configured to the bellows that cross section is one or several continuous S types by hydraulic expanding-forming, waveform ensures, waveform ruler
It is very little accurate.Shortcoming is limited by " S " type waveform, and shaping dies cannot use mechanical method from bellows after bellows shaping
On unload, can only use chemical method dissolve female die for forming method carry out mould unloading.In actual production, since mould cannot repeat
Use, one set of die can only process a product, thus of high cost, inefficiency.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of for manufacturing the detachable of S type metal bellows
Hydraulic expanding die, solves tradition S types bellow mold and lossless can not remove after forming, have and economize on resources, efficient
Feature.

Pipe lower half waveform 29 is contacted with pipe 13；
Such as Figure 27, another lower same procedure in previous step of cover half 6 is assembled, using bolt 9 and nut 10 under
Cover half through hole 30 is fixed, and completes the assembling of a pair of lower cover half 6；
Such as Figure 28, upper dynamic model 3 can be divided by one, one can divide middle dynamic model 4 and one can divide lower dynamic model 5 to assemble, and can divide
Blind threaded hole 21 can divide blind threaded hole 27 on the outside of lower dynamic model to be aligned to that will definitely divide middle dynamic model back threaded hole 25 on the outside of upper dynamic model
Middle dynamic model back threaded hole can be divided；
Such as Figure 29, one can divide dynamic model 3, and one can divide middle dynamic model 4 and one can divide the lower composition of dynamic model 5 can transfer
Mould, can divide dynamic model S type bellows upper half waveform 20, can divide waveform 23 in the middle part of middle dynamic model S types ripple and can divide lower dynamic model S types
Side waveform 26 forms S type bellows complete waveforms under bellows；
Such as Figure 30, it can deeply divide blind spiral shell on the outside of upper dynamic model respectively by middle dynamic model back threaded hole using holding screw 11
Pit 21 and blind threaded hole 27 can be divided to realize on the outside of lower dynamic model fix, used six holding screws 11 (Figure 21) in figure, obtained
Can transfer mould；
Such as Figure 31, to dynamic model back threaded hole among every place, holding screw 11 is screwed in into realization and is fixed；
Such as Figure 32, by one can transfer mould be assembled in device, middle dynamic model semicircle orifice 22 can be divided to be sleeved on guide post 8, can
The most inner side of waveform 23 is contacted with pipe 13 in the middle part of dynamic model S types ripple among point；
Such as Figure 33, by another can transfer mould use same procedure in previous step to assemble, passed through using bolt 9 and nut 10
Middle dynamic model through hole 24 can be divided to fix, completing a pair can the assembling of transfer mould；
Dynamic model in a pair 2 is assembled by similar method, 2 semicircle orifice 17 of dynamic model in a pair is sleeved on guide post 8, is used
Bolt 9 and nut 10 (such as Figure 19 Figure 20) are fixed by upper dynamic model through hole 19；Complete four pairs can transfer mould assembling such as Figure 34, make
Above dynamic model 2, relative distance that can be between transfer mould 4 and lower cover half 6 are fixed with cushion block 12, liquid is passed through into upper mold seat liquid injection hole 16
It is internal that pipe 13 (Figure 23) is filled with die holder liquid injection hole 33；
Such as Figure 35, the liquid pressing of initial inside pipe fitting is filled with, pipe 13 is in upper dynamic model 2 and can transfer mould, adjacent
Can transfer mould and can be between transfer mould and lower cover half 6 part slight expansion, at this time pipe 13 be deformed into preform pipe fitting
34, then remove cushion block 12, upper dynamic model 2, mutual distance that can be between transfer mould and lower cover half 6 pass through bulging part metals at this time
Ensure, keep hydraulic pressure constant, axial compressive force is applied to upper mold seat 1 by forcing press, closes adjacent die；
Such as Figure 36, loading is completed, preform pipe fitting 34 is deformed into S type bellows parts；Pressure in removal；
Bolt 9 and nut 10 are removed, divides middle dynamic model 4 radially to be dismantled along S types bellows the top, such as Figure 37；
Such as Figure 38, upper dynamic model 3 can be divided to move down the top, when 20 the thickest portion of side waveform on upper dynamic model S type bellowss can be divided
When point can be by S type 35 waveforms of bellows part after shaping, dynamic model 3 can be divided radially to be dismantled along S types bellows, then will
The top can divide lower dynamic model 5 to move up, and radially be dismantled along the S types bellows part 35 after shaping；Repeat step completion is all can transfer
Mould is dismantled, such as Figure 39；
Such as Figure 40, upper mold seat 1 and upper dynamic model 2 are moved up vertically and depart from guide post 8；
Such as Figure 41, the S types bellows part 35 after shaping is axially moveable taking-up, the S type bellows parts after being shaped
35；Cleaning mold, carries out next forming process.
