Abstract
The utility model discloses a graphite composite cylinder head gasket which comprises a gasket body and is characterized in that the gasket body comprises a metal plate with a plurality of through holes; burrs are processed on the upper surface and the lower surface of the metal plate in a spurting and punching way; and the two sides of the metal plate are coated with graphite plates. The graphite composite cylinder head gasket has the characteristic of simple technology, strong adaptability and lower manufacturing cost.
Description
Technical field
The utility model relates to a kind of pad, and especially a kind of graphite composite cylinder headrest is applicable to automobile, motorcycle IC engine cylinder body and the use of cylinder cap joint.
Background technique
Internal-combustion engine comprises cylinder head, cylinder head gasket, cylinder block; Cylinder head and cylinder block are respectively equipped with moving element; Cylinder head is fastened up and down with cylinder block and is connected; Cylinder head gasket is located in the fastening seam between cylinder head and the cylinder block, plays the effect of seal buckle joint close and protection cylinder head and cylinder block.What use always in automobile, motorcycle IC engine cylinder body and cylinder cap joint at present is metallic packing, has following several kinds: one, pure metal gasket seal, directly make by plasticity preferred metal material; Produce corresponding sealing lines at metallic surface through special process; Make metallic shim in seal process,, make potted line play the effect of sealing through the pressurized of cylinder cap and cylinder body; This kind metallic gasket belongs to the most conventional engine cylinder head system cylinder body sealed product, and heat resisting and pressure resisting property is good.
Two, the pad that forms of metal coat material; By metal is matrix, and surface applied has the material of certain compression resilience, and the intermediate metal material plays reinforing function; The coating material on surface plays seal action; The pad that this kind metal coat material forms, good sealing effect, heat resisting and pressure resisting property is good.
Metallic packing is generally used in presses in the motor greatlyyer, and operating temperature is high, and in the demanding environment of sealing surface accuracy of manufacturing to motor.Corresponding metallic packing manufacture cost is higher, and technology is comparatively complicated.
Summary of the invention
The utility model is not enough to existing technology, and a kind of graphite composite cylinder headrest is provided, and this kind graphite composite cylinder headrest has the advantages that technology is simple, applicability strong, manufacture cost is lower.
In order to solve the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of graphite composite cylinder headrest; Comprise shim body, said shim body comprises a sheet metal that some through holes are arranged, and the mode upper and lower surfaces through spurt, punching on the said sheet metal all is processed with burr; Said sheet metal both sides are coated with graphite cake, and this kind graphite composite cylinder headrest has the advantages that technology is simple, applicability strong, manufacture cost is lower.
In the technique scheme; Preferably; The through hole of said shim body also is provided with the metal guard ring; The position integral thickness of clad metal guard ring is higher than the height of graphite Composition spacer body, and the metal guard ring not only can play whole reinforing function to pad, can also in use better play the effect of sealability.
In the technique scheme; Preferably, at least simultaneously be provided with the overlay that is used to seal on the said shim body, overlay has certain compression resilience; In the sealing of cylinder body; Receive the pressure effect of cylinder cap and cylinder body, overlay fits tightly cylinder cap and cylinder body, makes it arrive good sealing effect.The preparation process of overlay is simple, cost is low, variability is strong, applied widely.
In the technique scheme, preferred, compression moulding has the sealing lines on the said shim body, and said shim body is positioned at the thickness at said sealing lines place greater than the thickness beyond the said sealing lines.Promptly on the body of Composition spacer, pass through the mode of compacting, moulding, produce corresponding sealing lines, make shim body and potted line present stepped distribution, when this composite gland bush was applicable to internal combustion engine, pressure was not very big working environment in the cylinder.Main feature is easy to process, and cost is lower.
The utility model compared with prior art has following beneficial effect: the utlity model has the characteristics that technology is simple, applicability strong, manufacture cost is lower.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 and Fig. 4; A kind of graphite composite cylinder headrest; Comprise shim body 0, shim body 0 comprises a sheet metal 1 that seven through holes 5 are arranged, and the mode upper and lower surfaces through spurt, punching on the sheet metal 1 all is processed with burr 4; Sheet metal 1 both sides are coated with graphite cake 2, and wherein three through holes 5 are coated with metal guard ring 3.
Under the pressurized situation of IC engine cylinder body and cylinder head, the position of the clad metal guard ring 3 in the gasket seal at first is squeezed, and the position that is stressed is the sealing position; Pressure is big more, and sealability is good more, and the graphite Composition spacer body 0 of the inside has certain compression rebound characteristic; In pressurized process, play the effect of stress compensation, when cylinder body and cylinder lid surface out-of-flatness; Through the variability characteristics of self, whole sealing surface is played the effect of sealing.
Referring to Fig. 2 and Fig. 4; A kind of graphite composite cylinder headrest comprises shim body 0, and shim body 0 comprises a sheet metal 1 that some through holes are arranged; Mode upper and lower surfaces through spurt, punching on the sheet metal 1 all is processed with burr 4; Sheet metal 1 both sides are coated with graphite cake 2, and wherein eight through holes 5 are coated with metal guard ring 3, also are coated with a circle overlay 6 on the one side at least on this shim body 0.
Under the pressurized situation of IC engine cylinder body and cylinder head; Overlay 6 is at first received extruding, because overlay 6 is highly even, nothing is broken off or packing phenomenon, overlay 6 has certain compression resilience; Overlay 6 fits tightly cylinder cap and cylinder body, makes it arrive good sealing effect.
Referring to Fig. 3 and Fig. 4; A kind of graphite composite cylinder headrest comprises shim body 0, and shim body 0 comprises a sheet metal 1 that some through holes 5 are arranged; Mode upper and lower surfaces through spurt, punching on the sheet metal 1 all is processed with burr 4; Sheet metal 1 both sides are coated with graphite cake 2, and compression moulding has sealing lines 7 on the said shim body 0, and said shim body 0 is positioned at the thickness at said sealing lines 7 places greater than the thickness beyond the said sealing lines 7.
Under the pressurized situation of IC engine cylinder body and cylinder head, at first be expressed to sealing lines 7 inboards, sealing lines 7 inboards fit tightly cylinder cap and cylinder body, make it arrive good sealing effect.
