Description
Technical field
The utility model relates to heat insulating device fields, and in particular to a kind of heat insulation shield with flange.
Background technique
Automobile exhaust system is to discharge the exhaust gas while the device for reducing exhaust emission and noise that automobile engine generates, by
Exhaust system will be transferred directly in the temperature of engine, therefore the temperature of exhaust system higher will generate the components of surrounding
It influences, to prevent problems, needs to obstruct the heat of exhaust system using heat insulation shield.
Chinese utility model patent CN201520695541.0 discloses a kind of exhaust system clarifier heat shield, clarifier
Heat shield includes heat shield I and heat shield II, and heat shield I and heat shield II are configured to spiral-lock in clarifier body outer surface
Structure, the inner wall of the two is respectively provided with heat insulation foam layer, can effectively improve the heat insulation and noise reduction effect of clarifier heat shield,
It has the advantages of simple structure and easy realization, is suitable for promoting the use of, but buckling structure usually seals and stickiness is poor, and then influence heat shield
Heat insulation and preservation effect.Chinese utility model patent CN200920289528.X discloses a kind of Combined exhaust pipe heat insulation cover,
The liner of bellows, internal layer including outer layer and the fixation end cap that collet both ends are set, the inner surface of bellows with it is interior
The outer surface of lining matches, and matches on the inside of the outer surface of bellows and fixed end cap, and ripple outer tube layer is made of aluminium foil,
Internal layer is made of glass fiber material, and liner is made of inorfil cotton heat-barrier material, heat insulation preferably, thermal insulation layer table
Face temperature is lower, and occupied space is smaller, mounting arrangements are simple, not easily to fall off, reliability is higher.But there are appearance fold,
The disadvantages of package poor appearance, thermal insulation property is still limited.It is time-consuming to take in addition there are carrying out package exhaust system by modes such as bandages
Power；Or heat insulation shield is welded and fixed by multiple-piece splicing, time-consuming and laborious, the disadvantages of existing simultaneously more weld seam, poor appearance, and
It is once welded by flange, it is poor that there are stickiness, the problems such as pricking the hand at flange and easily scratch.
For poor appearance, installation is time-consuming and laborious, weld seam is more, easily prick the hand and heat insulation effect it is poor the problems such as, one kind should be looked for
Heat insulation shield so that the heat insulation shield there is structure simple, good appearance, good effect of heat insulation and being not easy to prick the hand,
The advantages that scuffing.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of heat insulation shield with flange, the thermal insulation separation
Heat cover includes the first cover and the second cover, and the upper and lower ends of the first cover carry out flange twice respectively, obtain the first upper overturning
With the first lower flange, the upper and lower ends of the second cover carry out flange twice respectively, obtain the second upper overturning and the second lower flange.It is logical
Cross stacking and welding between the first upper overturning and the second upper overturning, the first lower flange and the second lower flange, the first cover and
Two covers be welded to each other the heat insulation shield that together, obtains have simple structure, good appearance, good effect of heat insulation and
It does not prick the hand, be not easy the advantages that scratching.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of heat insulation shield with flange, the heat insulation shield include the first cover and the second cover, and described the
The upper and lower ends of one cover carry out flange twice respectively, obtain the first upper overturning and the first lower flange, second cover it is upper
Lower both ends carry out flange twice respectively, obtain the second upper overturning and the second lower flange.
Further, first cover and second cover are welded to each other and are integrated；The first of first cover
Second upper overturning of upper overturning and second cover is stacked and is welded as a whole, the first lower flange of first cover and institute
The second lower flange for stating the second cover is stacked and is welded as a whole.Obtained heat insulation shield is covered on heat-preservation cotton surface, then solid
It is scheduled in exhaust system, has the effect of insulation, the flange welded can be then pressed downward if necessary, be fitted in exhaust
In system.
Further, first upper overturning and first lower flange are U-shaped, first upper overturning and described
The flange direction of one lower flange is towards a left side；Second upper overturning and second lower flange are Z-shaped, second upper overturning
Flange direction with second lower flange is towards a left side.
Further, first upper overturning, first lower flange, second upper overturning and second lower flange
It is formed by flange twice, using mold, tooling or offhand, flange angle is 90 ° each time, each time flange
Length range is 5mm-20mm.
Beneficial effect acquired by the utility model is:
