Abstract
The utility model relates to an ultrathin seal gasket. A seal gasket body comprises a meal core plate and oil-resistant asbestos plates or asbestos-Free fiberboards pressed to two sides of the metal core plate. The metal core plat is 0.05-0.15mm in thickness, and a plurality of through holes are evenly arranged on the metal core plate. Peripheral projecting turned edges of each two adjacent through holes are arranged towards two sides of the metal core plate respectively. The total thickness of the metal core plate and the oil-resistant asbestos plates or asbestos-Free fiberboards is 0.8-1.25mm. The ultrathin seal gasket is highly compressive and resilient, highly oil-resistant and less prone to leakage, creep resistance and stress relaxation of the ultrathin seal gasket are improved greatly, comprehensive sealing performance of the ultrathin seal gasket is improved greatly, and sealing reliability and durability are improved.
Description
Technical field
The utility model relates to a kind of ultrathin gasket seal, belongs to engine gasket chip technology field.
Background technique
Along with motor car engine is big, in light weight towards power, oil consumption is low, performance is good, and direction easy to use, that the life-span is long develops, and gasket seal should approach light weight, compact structure by wall, and unfailing performance is strong again, combination property is outstanding.This just requires except that the high-performance gas sealing, and lubricant oil and cooling liquid sealing also strengthen thereupon, and everything all requires the engine gasket piece performance reliable and stable.But existing gasket seal, motor and automobile constantly vibrations and fluid soak into down, damaged, seepage constantly occur, and influence the working life of motor.Some gasket seals adopt the oil resistant asbestos slate to process at present, though the oil resistant asbestos slate has oil resistance preferably, the compressibility of oil resistant asbestos slate and rebound degree are not high, and its creep resistant and stress relaxation ability can not further improve.Moreover, because some pilot holes and gasket seal Edge Distance on the gasket seal are less, in installation process and using process, also be prone to cause the damage of tearing of gasket seal.
Summary of the invention
The purpose of the utility model provides and a kind ofly can improve mechanical strength, and compressibility, rebound degree are good, and oil resistance is strong, a kind of ultrathin gasket seal that sealability is superior.
The utility model is that the technological scheme that achieves the above object is: a kind of ultrathin gasket seal; It is characterized in that: described gasket seal body comprises metal core board and is pressed together on the oil resistant asbestos slate of metal core board both sides or does not have asbestos fiber sheet; Metal core board thickness is at 0.05-0.15mm; And be laid with plurality of through holes on the metal core board; The protruding flange of adjacent two through hole periphery is provided with to the both sides of metal core board respectively, and metal core board and oil resistant asbestos slate or the total thickness of not having an asbestos fiber sheet are at 0.8-1.25mm.
Model utility adopts metal core board and is pressed together on the oil resistant asbestos slate of metal core board both sides or does not have asbestos fiber sheet; Especially metal core board is laid with plurality of through holes; And the flange of adjacent two through hole periphery is provided with to the both sides of metal core board respectively, not only makes the oil resistant asbestos slate of metal chip and its both sides or does not have asbestos fiber sheet to have engaging force preferably, and use the metal core board of 0.05-0.15mm; And has mechanical strength preferably; Make gasket seal have higher compression property and horizontal tearing toughness,, in installation and using process, can not cause to tear and damage breakage especially for some pilot holes on the gasket seal and gasket seal Edge Distance smaller part.The utility model with the oil resistant asbestos slate or do not have asbestos fiber sheet be pressed together on on the metal core board through after the vulcanizing treatment; Not only have compressibility and rebound degree preferably; And oil resistance is good, is difficult for seepage takes place, and its creep resistant and stress relaxation ability significantly improve; The comprehensive sealing performance of gasket seal is increased dramatically, has improved sealing reliability and durability.The utility model also has thickness at the 0.01-0.02mm rubber coating at oil resistant asbestos slate or the outer side surface that do not have an asbestos fiber sheet, can fill up motor through this envelope coating and connect the influence of the rough surface of sealing metal spare to sealing, can stop the seepage of liquid.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is made further detailed description.
Fig. 1 is the structural representation of the ultrathin gasket seal of the utility model.
Fig. 2 is that the sectional structure schematic representation is amplified at the A-A place of Fig. 1.
Wherein: 1-gasket seal body; 2-oil resistant asbestos slate, 3-metal core board, the protruding flange of 3-1-, 3-2-through hole, 4-rubber coating.
Embodiment
The ultrathin gasket seal of the utility model is mounted between the engine body and link except that the head gasket part, to play seal action.See Fig. 1, shown in 2, the ultrathin gasket seal of the utility model, gasket seal body 1 comprise metal core board 3 and are pressed together on the oil resistant asbestos slate 2 of metal core board 3 both sides or do not have asbestos fiber sheet that this no asbestos fiber sheet can adopt no asbestos aramid fibre sheet material material etc.See shown in Figure 2; The thickness of the metal core board 3 of the utility model is at 0.05-0.15mm; The THICKNESS CONTROL of this metal core board 3 is at 0.06-0.09mm, and like employing 0.07mm or 0.08mm metal core board 3, or the THICKNESS CONTROL of metal core board 3 is at 0.11-0.14mm; As adopt the metal core board 3 of 0.11mm or 0.12mm; Be laid with plurality of through holes 3-2 on the utility model metal core board 3, the protruding flange 3-1 of adjacent two through hole 3-2 periphery is provided with to the both sides of metal core board 3 respectively, makes the oil resistant asbestos slate 2 of metal core board 3 and its both sides or do not have asbestos fiber sheet to have binding ability preferably; Metal core board 3 and oil resistant asbestos slate 2 or the total thickness of not having asbestos fiber sheet are at 0.8-1.25mm, and this ultrathin type gasket seal is used for the sealing of engine body and other parts joint.See that Fig. 1, the ultrathin gasket seal shown in 2 are to be contained between engine body and the gear chamber, gasket seal body 1 is provided with and starts axis hole, camshaft hole, positioning hole and bolt hole etc.
See shown in Figure 2; Its oil resistant asbestos slate 2 of the ultrathin gasket seal of the utility model or the outer side surface that does not have an asbestos fiber sheet also have the rubber coating 4 of thickness at 0.01-0.02mm; Can fill up motor through this rubber coating 4 and connect of the influence of the rough surface of sealing metal spare, thereby stop fluid seepage sealing.
