Abstract
The invention discloses a method for manufacturing polymer-material sealing rings. Polymer materials are extruded and molded and then cut. The method only needs to change tools to obtain the sealing rings with shapes capable of meeting almost any demand. The inner wall and the outer wall of an extrusion tube are smooth, and the extrusion tube does not have die closing burrs and the defect of being polluted by die oil. The quality of the polymer-material sealing rings is improved, and the extrusion process is continuous. Thus, the production efficiency is greatly improved, the technology is simple, processing condition parameters are easily controlled, the production cycle is greatly shortened, and the processing cost is significantly reduced.
Description
Technical field
The present invention relates to sealing ring, specifically the manufacture method of macromolecular material sealing ring.
Background technology
Sealing ring is that a kind of cross section is for circular moulding circle, because its cross section is O type, therefore be called O RunddichtringO.Sealing ring is mainly used to grease-proof and waterproof preserving and sealing gas, prevents from revealing, and be most popular a kind of in hydraulic and pneumatic transmission system.O RunddichtringO, generally adopts acrylonitrile-butadiene rubber, natural rubber, neoprene, EP rubbers, fluorubber, silicon rubber and the manufacture of blend glue.Except O type, also have triangular form, square type, D type, T-shaped, square, heart type, X-type, five rib types, olive-type, star-like, flower bud type, drum type etc.
Different according to sealing ring material used, just produce in nature different classification, as 1. high-temperature resistant seal rings, 2. high-pressure-resistant sealed circle, 3. corrosion-resistant sealing ring, 4. wear-resistant sealing ring.
Macromolecular material sealing ring, the material being most widely used is aramid fiber, rubber, fluoroplastics, fluorubber and silica gel.
Aramid fiber take there is high strength, the aramid fiber of high mill amount carries out compounded sealed product as material of main part and the good special material of lubricity.Rubber be take rubber and as primary raw material, is added the auxiliary materials such as filler to make.The good good springiness of fluoroplastics and viton seal ring intensity, high temperature high voltage resistant, acid-fast alkali-proof oil resistant are anti-aging.
The production of present rubber seal all needs the operation through series of complexes such as mixing, mold pressing, sulfuration, finishings, and uses a lot of equipment as rubber mixing machine, conche, vulcanizer, forming machine etc.Process is complicated, and the production cycle is long, and technique is difficult to control, and equipment cost is high, die cost is high, and a mold can only be produced a kind of product.Aspect product quality, there is matched moulds burr in sealing ring, and be subject to Die Oil pollution etc.
Summary of the invention
The present invention is the deficiency that overcomes prior art, improves the quality of macromolecular material sealing ring, reduces production costs, and simplifies production technology, and a kind of manufacture method of macromolecular material sealing ring is provided.
The manufacture method of macromolecular material sealing ring of the present invention, is by polymer material extrusion moulding, then cutting.
The shape of extruding comprises the pipe that pipe, square tube, triangular pipe or cross section are other various shapes.Various shapes, can meet different needs.
One embodiment of the present invention are to make the outer telogenesis ripple drum type of the above-mentioned various pipe of extruding.Like this can be by extruding, the thickness of disposable restriction sealing ring, each ripple is exactly the thickness of a sealing ring, only need to cut according to ripple afterwards.
Further, the present invention also makes telogenesis ripple drum type in the above-mentioned various pipe of extruding.
In order to obtain more multi-form product, and guarantee product quality, the present invention also comprises that the pipe to extruding is managed interior processing while hot and/or pipe is processed outward.
The mode of cutting of the present invention comprises laser cutting or cutter cutting.Laser cutting is optimal way, because the tangent plane of laser cutting leaves no trace, smooth careful, precision is high.
Compare prior art, method of the present invention only need to change frock, just can obtain meeting the sealing ring of the shape that is almost any needs, and this cost than mold exchange is more much lower.And in method of the present invention, the inside and outside wall of extruding pipe is smooth, the disadvantage that does not have matched moulds burr and polluted by Die Oil.Extrusion is continuous in addition, thereby production efficiency improves greatly.In addition, method of the present invention, has greatly reduced production equipment, has an extruder, and technique is simple, does not need to carry out the vulcanization of rubber, and processing conditions parameter is easily controlled, and the production cycle shortens greatly, and processing cost significantly reduces.
Accompanying drawing explanation
Fig. 1 is the inside and outside drum type pipe front view of one section of corrugated of the inventive method extrusion molding gained.
Fig. 2 is the drum-type sealing ring top view of gained after cutting.
Fig. 3 is the sectional view of Fig. 2 upward view.
The specific embodiment
Embodiment 1
1, deployed aramid fiber material.
2, with extruder, be extruded into drum type pipe inside and outside ripple, as Fig. 1.
3, with laser cutting method, in ripple junction, cut, obtain drum-type sealing ring, see Fig. 2, Fig. 3.Wherein the A of Fig. 3, B face are cydariform, smooth, do not have matched moulds burr.
Embodiment 2
1, deployed silicon rubber material.
2, with extruder, be extruded into inside and outside level and smooth square tube.
3, with being laser-cut into square seal ring.
Embodiment 3
1, deployed silicon rubber material.
2, the pipe that being extruded into outside with extruder is ripple drum type, inwall is level and smooth.
3, with laser cutting method, in ripple junction, cut, obtain the flat circular sealing ring of outer cydariform in external drum.
