Abstract
The skeleton material of modified plastics for sealing ring with external skeleton features that said skeleton is made up by thermal forming of reinforced thermoplastic plastics instead of metal, so featuring no rust and firm combination with rubber.
Description
The present invention relates to a kind of replacing of seal ring framework material, be specially adapted to external frame type sealing ring.
Seal ring system is made up of framework material and rubber.By the lip of rubber made, with its material characteristics and structural characteristics with should being close to axle, thereby reach sealing.Framework material is with the stability of its rigidity enclosed structure, makes the rubber lip can be with being close to travel axis.External frame type sealing ring means that skeleton is positioned at the outer of rubber, directly the seal ring that contacts with the assembling stand hole.Skeleton system is added five and forms with die-cut by sheet metal.But there are so several problems in this skeleton: the one, and surface corrosion easily, the 2nd, with the rubber junction plane, just be the otch of punch die in the skeleton, limit portion is comparatively sharp-pointed, and Chang Yi causes early fallout.
The object of the present invention is to provide and a kind ofly be difficult for corrosion, combine firm framework material with rubber.
The present invention is achieved in that with thermoplasticity reinforced plastic and replaces metal frame, adopts injection moulding machine shaping.Thermoplasticity reinforced plastic system adopts glass fibre, with the modified product after the coupling agent treatment.Some thermoplasticity reinforced plastic, its strength and stiffness and plain carbon steel are close.Reach the tensile strength of grey cast iron as 30% glass fiber enhanced nylon plastics, thereby rigidity and dimensional accuracy are better, structure that can the stabilized seal circle has prevented corrosion again.
Because the thermal plastic kind is many, the molecular polarity span is big, thereby can select close with rubber packing material polarity, bonding favourable plastics.Adopt the molding and forming skeleton,, implement easier so skeleton is easy to process.
Below with reference to accompanying drawing, invention is described in further detail:
Fig. 1 implements die profile of the present invention.
With reference to Fig. 1, seal element (1) skeleton inserts (2) lower module (a 3) ring-type cast gate (4) of making by rubber.Fig. 2 is the modified plastic external frame type sealing ring after the completion of processing, and (5) are the modified plastic external frame.Enforcement of the present invention was divided into for two steps: promptly first vulcanized rubber element, injection moulding skeleton again.Rubber is through cooperating, process heating in the mould that is placed on Fig. 1, pressurization, and its shape of skeleton inserts (2) is similar to skeleton (5) with size, seals ring-type cast gate (4) when sulfuration rubber is entered.Sulfuration finishes, and takes out skeleton inserts (2), and mould is inverted, and just can carry out the injection moulding of skeleton.
The prescription of skeleton is as follows:
Nylon 100 coupling agent treatment glasses 30
Material carries out injection moulding after cooperation, granulation, heating, become figure (2) product after the demoulding.
Claims (3)
1, seal ring of being made up of rubber sealing element (1) and skeleton (2) is characterized in that skeleton (2) made by modified plastics.
2,, it is characterized in that skeleton (2) made by the thermoforming processing method by modified plastics by the seal ring of claim 1 regulation.
3, by the seal ring of right 1 or right 2 regulations, it is characterized in that processing technology is to make rubber sealing element (1) earlier, make inserts with (1) again and make skeleton, become seal ring.
