Description
Technical field
Technical field of rubber seal is the utility model is related to, more particularly to a kind of diesel fuel filter base inner clip cloth film
Piece.
Background technology
Rubber fabric clamped film sheet is for the rubber seal in automobile filter, and the product must have excellent oil resistivity
Can and low temperature under dynamic resilience performance, and after product surrounding assembling compresses, it is necessary to have heat-resisting, endurance bending 100,000 times
Keep permanent seal performance.
Diesel fuel filter base has oil pumping system, and wherein oil pumping system is made up of many parts, mainly enters oil pump
Filtered in cleaner, and the folder cloth in the folder cloth diaphragm in base greatly improves the fatigue resistance of folder cloth diaphragm, leads to
Cross raw discontinuity suction pump oil between the folder cloth motion of membrane.
Current external processing technology is taken, and base fabric two sides first is carried out into pasting（NBR raw materials）Processing, then carry out low temperature
It is compressing.NBR rubber and the base fabric handled well are subjected to high temperature vulcanized processing again after taking-up.Drawback be present：Base fabric pasting work
Skill is cumbersome, and qualification rate is relatively low；Coat slurry base fabric carry out low temperature it is compressing after it is yielding, and the parking space of temporary compared with
Greatly；When the base fabric suppressed carries out high temperature vulcanized again, base fabric creeping phenomenon is easily produced, while cost is high.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of diesel fuel filter base inner clip cloth film
Piece.
Technical scheme is used by the utility model：
A kind of diesel fuel filter base inner clip cloth diaphragm, including block, Inner arc, external arc, hypotenuse, big Inner arc, cap
Eaves, marginal ridge, the block are cylindric volume slot type structure, and its bottom margin is provided with radian turning, the block it is cylindric straight
Side connection Inner arc side, Inner arc opposite side connection external arc side, external arc opposite side connection hypotenuse one end, hypotenuse are another
End connects big Inner arc side, and the big Inner arc opposite side connection the brim of a hat is inner, and the brim of a hat outer end sets marginal ridge.
A kind of described diesel fuel filter base inner clip cloth diaphragm, is made up of, the folder cloth canvas filler layer and vulcanised rubber layer
Layer is to be put into by special base fabric in NBR fluid binders after immersion, is formed after naturally dry；The canvas filler layer is placed in lower mould
On, and fixed by lower mould with the cloth clamp device set on middle mould, then middle mould is closed, and strain clamp cloth, injection rubber to upper mould, stream
Drop down in mould, partial rubber passes through out of cloth inserted hole after matched moulds, rubber is formed superficies with folder cloth by heating and is
The integrative-structure of the folder cloth of NBR fluid binders and the vulcanised rubber layer B of internal layer.
Further, the cylindric straight flange of the block connects Inner arc side, Inner arc opposite side connects external arc side,
External arc opposite side connection hypotenuse one end, the hypotenuse other end connect big Inner arc side, big Inner arc opposite side is connected in the brim of a hat
End, above-described junction is that arc transition is smoothly connected.
Further, the canvas filler layer edge is far from marginal ridge base 0-1mm.
Compared with prior art, the beneficial effects of the utility model are：With base fabric soaking paste technique simply, conveniently；Soaking paste
Base fabric be not required to carry out after-treatment can process use；Base fabric processing cost is low, time saving and energy saving；It is simple to vulcanize processing technology；
Product class's yield is high, and manufacturing cost substantially reduces；Product appearance qualification rate is high, no base fabric creeping phenomenon.

Fig. 2 is a kind of mplifying structure schematic diagram of diesel fuel filter base inner clip cloth diaphragm.
Embodiment
A kind of diesel fuel filter base inner clip cloth diaphragm, including block 1, Inner arc 2, external arc 3, hypotenuse 4, big Inner arc
5th, the brim of a hat 6, marginal ridge 7, the block 1 are cylindric volume slot type structure, and its bottom margin is provided with radian turning, the block 1
Cylindric straight flange connection Inner arc 2 side, the opposite side of Inner arc 2 connection external arc 3 side, the opposite side of external arc 3 connection hypotenuse 4
One end, the other end of hypotenuse 4 connect the big side of Inner arc 5, and the big opposite side of the Inner arc 5 connection the brim of a hat 6 is inner, and the outer end of the brim of a hat 6 is set
Marginal ridge 7.
A kind of described diesel fuel filter base inner clip cloth diaphragm, is made up of, the folder canvas filler layer A and vulcanised rubber layer B
Layer of cloth A is to be put into by special base fabric in NBR fluid binders after immersion, is formed after naturally dry；The canvas filler layer is placed in down
On mould, and fixed by lower mould with the cloth clamp device set on middle mould, then close middle mould, strain clamp cloth, injection rubber to upper mould,
Trickle into middle mould, partial rubber passes through out of cloth inserted hole after matched moulds, rubber and folder cloth is formed superficies by heating
The vulcanised rubber layer B of folder cloth and internal layer for NBR fluid binders integrative-structure.
Further, cylindric straight flange connection Inner arc 2 side of the block 1, the opposite side of Inner arc 2 connection external arc 3
Side, the opposite side of external arc 3 connection hypotenuse 4 one end, the other end of hypotenuse 4 connect the big side of Inner arc 5, the big opposite side of Inner arc 5
It is inner to connect the brim of a hat 6, above-described junction is that arc transition is smoothly connected.
Further, the canvas filler layer A edges are far from the base 0-1mm of marginal ridge 7.
Further, after testing, producing folder cloth diaphragm according to structure of the present utility model has following performance：
