Abstract
The present invention relates to a kind of many ripple hydraulic pressure automatic forming methods of below 10mm minor diameters metal bellows, comprise the following steps：Step 1：Mold cavity gap is determined, is 0.2mm~0.25mm；Step 2：Hydraulics inlet fixture latus rectum is determined, is 3~4mm；Step 3：Fitter assembly, makes the template of mould be in horizontality；Step 4：Match No. 68 antiwear hydraulic oils；Step 5：On pipe insertion entrance fixture, make mould matched moulds, give pipe pressurising, promote pipe bottom to be moved to entrance fixture, make the template contacts between mould, then release, pull open mould, take out shaped article bellows.The present invention, which solves existing method, can not realize the defect of many ripple hydraulic pressure automatic mouldings of the following minor diameter metal bellows of Φ 10mm, solve the problems, such as production and processing.
Description
Technical field
The invention belongs to the application field of liquid shaped by fluid pressure, it is related to a kind of many ripples of below 10mm minor diameters metal bellows
Hydraulic pressure automatic forming method.
Background technology
The processing for more than diameter 10mm metal bellows can realize hydraulic pressure automatic moulding at present, but right
But it is difficult to realize in many ripple hydraulic pressure automatic mouldings of the following minor diameter metal bellows of diameter 10mm, because original for major diameter
Processing method causes bellows to scrap with minor diameter metal bellows, can not produce qualified metal bellows, then needs
Further explored.
The content of the invention
It is difficult to for many ripple hydraulic pressure automatic mouldings of the following minor diameter metal bellows of existing Φ 10mm, yield rate is low
Deficiency, the present invention, which provides one kind, can realize minor diameter metal bellows automatic moulding, the high forming method of qualification rate.
The technical scheme that the present invention takes is：A kind of many ripple hydraulic pressure automatic forming methods of minor diameter metal bellows, including
Following steps：
Step 1：Mold cavity gap is determined, is 0.20mm~0.25mm；
Step 2：Hydraulics inlet fixture latus rectum is determined, is 3.0~4.0mm；
Step 3：Fitter assembly, makes the template of mould be in horizontality；
Step 4：Match No. 68 antiwear hydraulic oils；
Step 5：On pipe insertion entrance fixture, gross pressure is adjusted on a hydraulic press, is 13MPa, makes mould matched moulds, gives
Pipe pressurising, promotes pipe bottom to be moved to entrance fixture, makes the template contacts between mould, then release, pull open mould, takes out
Shaped article bellows.
The wavy metal pipe diameter of above method shaping is less than 10mm.
Advantageous effects：The present invention is by groping the parameter in the processing of minor diameter metal bellows, especially mould type
Cavity gap and hydraulics inlet are stimulated the menstrual flow, and many ripple hydraulic pressure of the following minor diameter metal bellows of Φ 10mm can not be realized by solving existing method
The defect of automatic moulding, realizes working ability, improves processing efficiency, can be improved on the original basis, and it is improved
Cost is small, and the value of generation is high.
Brief description of the drawings
Fig. 1 is mould template side view；
Fig. 2 is bellows forming hole enlarged diagram in Fig. 1.
Embodiment
The present invention is described in further detail with reference to specific embodiment and Figure of description.
Embodiment 1：A diameter of 10mm bellows is processed, step is as follows：
Step 1：Mold cavity gap is determined, is 0.20~0.22mm；
Step 2：Hydraulics inlet fixture latus rectum is determined, is 3.5~4.0mm；
Step 3：Fitter assembly, makes the template of mould be in horizontality；
Step 4：Match No. 68 antiwear hydraulic oils；
Step 5：On pipe insertion entrance fixture, gross pressure is adjusted on a hydraulic press, is 13MPa, makes mould matched moulds, gives
Pipe pressurising, promotes pipe bottom to be moved to entrance fixture, makes the template contacts between mould, then release, pull open mould, takes out
Shaped article bellows.
Embodiment 2：A diameter of 8mm bellows is processed, step is as follows：
Step 1：Mold cavity gap is determined, is 0.22~0.25mm；
Step 2：Hydraulics inlet fixture latus rectum is determined, is 3.0mm；
Step 3：Fitter assembly, makes the template of mould be in horizontality；
Step 4：Match No. 68 antiwear hydraulic oils；
Step 5：On pipe insertion entrance fixture, gross pressure is adjusted on a hydraulic press, is 13MPa, makes mould matched moulds, gives
Pipe pressurising, promotes pipe bottom to be moved to entrance fixture, makes the template contacts between mould, then release, pull open mould, takes out
Shaped article bellows.
As shown in Figure 1, 2, its relative dimensions is mould template schematic diagram in the bellows for processing a diameter of 8mm：Template
Thickness is 1.6mm, tolerance+0.02mm, with stepped hole, and stepped hole surface roughness is 0.2, the less hole of step bore dia
Footpath is 9.78mm, and tolerance+0.03mm, the aperture being relatively large in diameter is 14.8mm, and tolerance is+0.1mm, and thickness is 0.95, tolerance+
0.02mm, template total length bending is not more than 0.02.
Mould tolerance uniformity is controlled in forming process, makes the control in mould patch ripple pipe gap in 0.2mm or so,
And each compact hand of template is touched and not loosened.The present invention installs gap by designing suitable die size and relevant interface, controls phase
Key parameter is closed to realize breakthrough that production and processing is required, that is, realize diameter it is automatic less than the hydraulic pressure of 10mm metal bellows into
Type is processed.
The design in mold cavity gap and entrance fixture latus rectum is not to be simply reduced or increased, and it is applicable interval narrow,
Only 1mm less than adjustment amount, it is careless slightly i.e. can scrap, difficulty is big.
