Abstract
The invention discloses a kind of car clutch regulating valve tubular seals circle, including sealing ring body, the sealing ring body is the EP rubbers part of tubulose.Using high temperature short time cure technique, production efficiency had both been substantially increased, has in turn ensured that properties of product are stablized, improves product qualification rate；EP rubbers higher using hardness, resistance to braking fluid is made, therefore manufactured car clutch regulating valve is small with tubular seals circle compressive deformation, and volume change is small, there is good wearability, good seal performance；After sulfidization molding, after refrigerating process trimming, the technique of high-pressure spraying and ultrasonic wave combined type cleaning, it is ensured that product meets the requirement of cleannes, avoids generating pollution, wide market in seal process.
Description
Technical field
The present invention relates to sealing ring manufacturing technology field more particularly to a kind of car clutch regulating valve tubular seals circles
And its manufacturing process.
Background technique
Car clutch regulating valve is widely applied on various cars.Clutch and regulating valve with tubular seals circle be from
Major function: the key element of clutch regulating valve in the normal driving process of car, when speed change shifts gears, works as driver
Let slip the clutch, by clutch and regulating valve, makes clutch slave cylinder uniformly push shift fork under the action of clutch master cylinder
Connection gearbox is to achieve the purpose that shift.Clutch and regulating valve tubular seals circle major function is exactly to adjust in clutch
Valve plays sealing function when working, and is that the accuracy requirement of key part inherent quality and size therein is very high.Separately due to it
Work is in brake fluid, to avoid the pollution to brake fluid, so requiring the cleannes of the product very high.
Clutch and regulating valve relies primarily on import with tubular seals circle at present, external mainly using the production work of injection
The production cost of skill, production efficiency bottom, product is higher.In addition for using ultrasonic cleaning process, the metallic particles pollution of product
It cannot control.It is that the present invention to be solved that a kind of car clutch regulating valve, which how to be designed, with tubular seals circle and its manufacturing process
Certainly the technical issues of.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of car clutch regulating valve tubular seals circle and its manufactures
Technique.
The present invention is realized by following technological means solves above-mentioned technical problem:
A kind of car clutch regulating valve tubular seals circle, including sealing ring body, the sealing ring body are tubulose
EP rubbers part.
Preferably, a kind of car clutch regulating valve tubular seals circle, the sealing ring is with EP rubbers
For matrix, lubricant, crosslinking agent, plasticizer, reinforcing agent, metal oxide is added and is prepared.
Preferably, a kind of car clutch regulating valve tubular seals circle, the lubricant is paraffin, described
Crosslinking agent be ethylene glycol dimethacrylate, the plasticizer is dibutyl phthalate (DBP), and the reinforcing agent is spraying
Carbon black, the metal oxide are zinc oxide and aluminium oxide.
A kind of manufacturing process of car clutch regulating valve tubular seals circle, comprising the following steps:
(1) it is put into mixer after mixing EP rubbers and each raw material in addition to crosslinking agent to be kneaded, in open mill after mixing
Crosslinking agent mixing is neutralized, thin logical bottom sheet is parked；
(2) the die cavity straight forming of mold will be entered on the sizing material after parking, mold transmits pressure injection mold using multi-cavity, using high temperature
The vulcanization of short term curing technique, after the completion of vulcanization, demoulds to obtain semi-finished product；
(3) semi-finished product are directly placed into freezing equipment, go deburring, then use high-pressure spraying equipment by the thin of product surface
The removal of thin-sheet dust；
(4) it cleans in high-pressure spraying equipment and then uses supersonic wave cleaning machine by metallic particles that may be present in sealing ring
Understand completely with hard non-metallic particle.
The present invention has the advantages that not only having substantially increased production efficiency, but also guarantee using high temperature short time cure technique
Properties of product are stablized, and improve product qualification rate；EP rubbers higher using hardness, resistance to braking fluid is made, therefore is made
Car clutch regulating valve it is small with tubular seals circle compressive deformation, volume change is small, there is good wearability, sealing performance
It is good；After sulfidization molding, after refrigerating process trimming, the technique of high-pressure spraying and ultrasonic wave combined type cleaning, it is ensured that product meets
The requirement of cleannes avoids generating pollution, wide market in seal process.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of sealing ring of the present invention.
Specific embodiment
