Background technology
For clutch in the bell housing between engine and gearbox, the output shaft of clutch is exactly the defeated of gearbox
Enter axis.In vehicle traveling process, driver can tip into or out clutch pedal as needed, make engine and gearbox
It is temporarily separated and gradually engages, to cut off or transmit the power that engine is inputted to speed changer.So clutch surface is in automobile
The process frequency of use of traveling is especially high, and generally use is hot-forming during being processed preparation to clutch surface,
But need to squeeze into slurry in mold during hot-forming, but due to needing to increasing clutch during preparing
The intensity and frictional force of device, to need to be added without asbestos yarn（Cloth）, to need to carry out to carry out hot-pressing processing to semi-finished product.
Invention content
The purpose of the present invention is to provide a kind of processing of car clutch face sheet to be hot pressed into technique, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the present invention provides the following technical solutions：
A kind of processing of car clutch face sheet is hot pressed into technique, includes the following steps：
S1, material prepare, will be without asbestos yarn（Cloth）Then impregnating resin puts into resin solution in impregnation trough, and runin machine 2~
It 3 minutes, will be without asbestos yarn after determining that equipment is working properly（Cloth）It is passed through between two rollers.Regulating roller is away from control resin contains
Amount.Soaked without asbestos yarn（Cloth）It should neatly dry in the air and be put on rack, then gluing is starched, and the adhesive tape cut out is measured 200 ㎏, input
In beater, by dipped resin without asbestos yarn（Cloth）Impregnation is carried out by cement dipping machine, is then being carried out around embryo processing, around embryo
When to cutting out without asbestos yarn（Cloth）It is weighed, for same product, weight difference will control：± 5 grams；
S2, compacting prepare, and the material progress for preparing semi-finished product is hot-forming, and material is sent into mold by push rod,
Then carried out hot-forming, when being suppressed, the temperature of compacting is 165 DEG C, and unit pressure is 20~26 Mpa, also
There is the pressing time according to the thickness of the semi-finished product of compression moulding, calculates according to 1~1.5 min/mm, to be led in pressing process
Deflation time is wanted, 20~35s is calculated when reaching pressure from press；
S3, compacting terminate, and the heat treatment for product carry out a step are needed, in the process being heat-treated, between product
It keeps at a distance, at the end of heating, when oven temperature can open chamber door less than 100 DEG C；
S4, the examination and test of products are tested comparison according to examination criteria.
Preferably, in step sl, during carrying out around embryo, the outer diameter of blank should be less than 10 ㎜ of product outer diameter, hair
The internal diameter of embryo should be greater than 10 ㎜ of product internal diameter.
Preferably, in step s 2, it is 165 DEG C for the temperature of compacting, and the range of temperature difference will be controlled at 165 DEG C
（±5）It is interior.
Preferably, in step s3, at the end of maximum temperature, heating power supply is cut off.After continuing air blast 30min, close total
Power supply.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention processes hot pressing with conventional vehicle clutch surface
Compare at technique, using hot press forming technology so that after embryo, semifinished material is suppressed, and convenient for pair
The size of die size is adjusted, so that production efficiency improves, and when suppressing semifinished material so that
The waste for reducing material, to cost-effective.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with specific embodiment, to this
Invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, not
For limiting the present invention.
A kind of processing of car clutch face sheet is hot pressed into technique, includes the following steps：
S1, material prepare, will be without asbestos yarn（Cloth）Then impregnating resin puts into resin solution in impregnation trough, and runin machine 2~
It 3 minutes, will be without asbestos yarn after determining that equipment is working properly（Cloth）It is passed through between two rollers.Regulating roller is away from control resin contains
Amount.Soaked without asbestos yarn（Cloth）It should neatly dry in the air and be put on rack, then gluing is starched, and the adhesive tape cut out is measured 200 ㎏, input
In beater, by dipped resin without asbestos yarn（Cloth）Impregnation is carried out by cement dipping machine, is then being carried out around embryo processing, around embryo
When to cutting out without asbestos yarn（Cloth）It is weighed, for same product, weight difference will control：± 5 grams；
S2, compacting prepare, and the material progress for preparing semi-finished product is hot-forming, and material is sent into mold by push rod,
Then carried out hot-forming, when being suppressed, the temperature of compacting is 165 DEG C, and unit pressure is 20~26 Mpa, also
There is the pressing time according to the thickness of the semi-finished product of compression moulding, calculates according to 1~1.5 min/mm, to be led in pressing process
Deflation time is wanted, 20~35s is calculated when reaching pressure from press；
