Description
Technical field
The present invention relates to a kind of eccentric bushing combiner and manufacturing process thereof, particularly relate to a kind of eccentric sleeve for cracker combiner and method of manufacturing technology thereof.
Background technology
The production industry such as colliery and mine be unable to do without the use of disintegrating machine.Because disintegrating machine applying working condition is severe, service time the objective factor such as overlength impact, cause eccentric bushing combiner needs the often replacing in disintegrating machine, have a strong impact on production efficiency and the economic benefit of exploitation enterprise.People through overtesting inside and outside cast steel eccentric bushing by casting method shape casting nylon (MC nylon) instead of over commonly use babbit, bring a revolution to extraction industry.But owing to casting the characteristic of nylon and cast steel material, make the surface conjunction power of casting nylon and cast steel material almost nil, although have employed the frame for movement such as T-slot and connecting hole is applied in casting nylon molding technique, to reaching the adhesion increasing casting nylon and eccentric steel bushing, but due to bi-material percent thermal shrinkage difference greatly (percent thermal shrinkage of casting nylon is that the twice of cast steel material is many), when eccentric bushing component after shaping is cooled to uniform temperature, namely there is usual said " freestone " phenomenon of nylon inner sleeve and cast steel eccentric bushing absciss layer and people, this just determines the hidden danger that the eccentric bushing after combination exists " freestone ", product percent of pass after making to combine is low, processing difficulties, the uniformity of product is poor, quality is unstable, even if the life of product of having paid is also unpredictable, more seriously in casting process, peculiar smell is excessive, pernicious gas volatilization is many, have a strong impact on the healthy of manufacturing enterprise employee and the surrounding people.Solve the environmental issue in process of producing product, the qualification rate and the uniformity that improve product are extremely urgent for this reason.
Summary of the invention
Goal of the invention
For the problem such as above-mentioned, the invention provides a kind of eccentric bushing combiner brand new and its manufacturing process, its objective is improve the qualification rate of product, uniformity, " freestone ", extend product service life and solve the problems such as peculiar smell in production process is excessive.
Technical scheme
A kind of eccentric bushing combiner, for Split assembled structure, it is characterized in that: combined by cast steel eccentric bushing, casting cotton garment and casting nylon inner sleeve and form, the inside of cast steel eccentric bushing is provided with casting nylon inner sleeve, and the outside of cast steel eccentric bushing is provided with casting cotton garment; Between the inner surface and the outer surface of cast steel eccentric bushing of casting cotton garment, scribble the first cementing medium, casting cotton garment is bonding with cast steel eccentric bushing by the first cementing medium; Between the outer surface and cast steel eccentric bushing inner surface of casting nylon inner sleeve, scribble the second cementing medium, casting nylon inner sleeve is bonding with cast steel eccentric bushing by the second cementing medium.
Eccentric bushing combiner is equipped with auxiliary bonding through hole, is all fixed by screw and nut precession auxiliary bonding through hole between the casting nylon inner sleeve of cast steel eccentric bushing and its inside and the casting cotton garment of outside.
The gap of 0.15-5mm is left between casting nylon lining the outer surface of and cast steel eccentric bushing endoporus.
The gap of 0.15-5mm is left between casting cotton garment inner surface and cast steel eccentric bushing cylindrical.
A manufacturing process for eccentric bushing combiner described above, is characterized in that: adopt cold working in conjunction with bonding method, complete the overall process that eccentric bushing combiner manufactures; Nylon inner sleeve and casting cotton garment casting respectively will be cast, (the blank of casting after processing, for meeting adhesive property, appearance and size will be mated with cast steel eccentric bushing, gluing of surfaces meets the requirement of roughness) combine with cast steel eccentric bushing, smear adhesive respectively by the casting nylon inner sleeve after processing, casting cotton garment and cast steel eccentric bushing and carry out splicing formation first cementing medium and the second cementing medium, then carry out drying, be finally machined into finished product.
The roughness of casting nylon inner sleeve, casting cotton garment and cast steel eccentric bushing gluing of surfaces is 1.6-25.
After casting nylon inner sleeve and casting cotton garment machine with cast steel eccentric bushing by the bonding combination of adhesive, casting nylon inner sleeve and the gluing of surfaces casting cotton garment need to carry out surface active and cleaning with dilution heat of sulfuric acid, watery hydrochloric acid, dilute nitric acid solution or soda bath.
After casting nylon inner sleeve and casting cotton garment and cast steel eccentric bushing have gluedd joint, be aided with the bonding screw of adhesive and nut is fixed.
Advantage and effect
