Description
Technical field
The present invention relates to rubber diaphragm processing technique field, more particularly to a kind of shaping side for rolling rubber diaphragm fabric
Method.
Background technology
Aircraft starts fuel regulator with rubber diaphragm is rolled, by experiencing engine base pressure and atmospheric pressure
Difference, moved up and down in engine starting and docking process and play sealing function between oil and gas.
The rubber diaphragm has relied on import always since XX-2 fuel oils start adjuster identification.Due to delivery cycle and confession
Goods quality is difficult to control, and influences the supporting delivery of product, and to solve delivery cycle and delivery quality quality problems, rubber diaphragm is opened
Open up production domesticization research work.
Rolling rubber diaphragm is compositely suppressed to form by rubber and fabric, and fabric mainly strengthens for rubber diaphragm, so as to
Rubber diaphragm can bear higher 1.5~2.0MPa of pressure.
The fabric distribution of the domestic part of XX-2 rubber diaphragms of technology production at present is as shown in figure 1, the fabric distribution of import partses
It is as shown in Figure 2 with domestic part fabric distributional difference.Main Differences are that the fabric of import partses is surface coated from cushion rubber, and domestic
Part fabric is coated from cushion rubber bottom.
The shortcomings that prior art is that domestic part rubber diaphragm is after carrying out simulating life-span examination 1000 hours, rubber diaphragm
There is blind crack in cushion rubber root, in order to avoid cracked, it is necessary to which the moulding process of fabric is studied and improved.
The content of the invention
In order to solve the above technical problems, The present invention provides a kind of forming method for rolling rubber diaphragm fabric so that
For rubber diaphragm after improvement after carrying out simulating life-span examination 1000 hours, the feature and presentation quality of rubber diaphragm are intact,
Properties of product reach import partses level.
The present invention is to be achieved through the following technical solutions：
A kind of forming method for rolling rubber diaphragm fabric, comprises the following steps：
1) fabric handled after hardening is fixed on the cavity plate of shaper with support ring, and uses screw-clamped；
2) punch-pin of shaper is buckled on cavity plate, to fabric under conditions of being 100 DEG C in temperature with vulcanizing press
Sizing 5~10 minutes, ultimately forms the stereotyped fabric consistent with rubber diaphragm profile；
3) stereotyped fabric is placed on the cavity plate of production mould, stereotyped fabric fixed with support ring,
And with screws clamp, then adhesive tape is placed in the aprons slot of production mould cavity plate；
4) thin film is uniformly affixed in the punch-pin of production mould, will finally posts the punch-pin of the production mould of thin film
With the cavity plate matched moulds vulcanization of production mould in step 3), final production goes out the rubber that fabric coats from the outer surface of rubber diaphragm cushion rubber
Glue film.
Also include before described step 1)：
1) first by fabric treatment fluid, processing hardening.
Compared with prior art, the present invention has technique effect beneficial below：
The forming method provided by the invention for rolling rubber diaphragm fabric so that home rubber diaphragm fab-ric can be from rubber
Diaphragm cushion rubber outer surface coats, and improves life-span and the reliability of rubber diaphragm.Domestic part rubber diaphragm after improvement is being carried out
After simulating life-span examination 1000 hours, the feature and presentation quality of rubber diaphragm are intact, and properties of product reach import partses level.
Solve the problems, such as that rubber diaphragm cushion rubber position is cracked.

Embodiment
With reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
Referring to Fig. 3 to Fig. 9, a kind of forming method for rolling rubber diaphragm fabric, comprise the following steps：
1) fabric handled after hardening is fixed on the cavity plate of shaper with support ring, and uses screw-clamped；
2) punch-pin of shaper is buckled on cavity plate, to fabric under conditions of being 100 DEG C in temperature with vulcanizing press
Sizing 5~10 minutes, ultimately forms the stereotyped fabric consistent with rubber diaphragm profile；
3) stereotyped fabric is placed on the cavity plate of production mould, stereotyped fabric fixed with support ring,
And with screws clamp, then adhesive tape is placed in the aprons slot of production mould cavity plate；
4) thin film is uniformly affixed in the punch-pin of production mould, will finally posts the punch-pin of the production mould of thin film
With the cavity plate matched moulds vulcanization of production mould in step 3), final production goes out the rubber that fabric coats from the outer surface of rubber diaphragm cushion rubber
Glue film.
Also include before described step 1)：
1) first by fabric treatment fluid, processing hardening.
Specifically, the present invention makes fabric the shape consistent with rubber diaphragm profile in advance by fabric shaper,
