Description
Technical field
The present invention relates to method for packing and the aftertreatment assembly thereof of a kind of catalyst converter carrier.
Background technology
Prior art generally uses to be filled in metal shell by carrier and liner, uses special trimmer to encapsulation afterwards
Housing carries out undergauge shaping, and finally the end cone after the welding punch forming of its two ends carries out the manufacture of aftertreatment assembly.But, weldering
Connect and need consuming bigger man-hour and cost, conventional housings trimmer equipment cost to put into the biggest with punching press end cone.It addition, in weldering
The place of connecing easily forms inefficacy, thus affects the durability of product.
Summary of the invention
It is an object of the invention to provide that a kind of method for packing is simple and the encapsulation of properties of product reliable catalyst converter carrier
Method and aftertreatment assembly thereof.
For achieving the above object, the present invention adopts the following technical scheme that
As further improved technical scheme of the present invention, the method for packing of a kind of catalyst converter carrier, it includes walking as follows
Rapid:
S1: the integral housing of a hollow is provided；
S2: liner is provided, and described liner is wrapped on catalyst converter carrier；
S3: the described catalyst converter carrier being enclosed with described liner is filled in described housing；
S4: the housing utilizing spinning machine pair to contact with described liner carries out spinning, makes the diameter of described housing narrow down to
Aimed dia, and the surface pressure produced by compressing described liner keeps described catalyst converter carrier not axle inside described housing
To vibration；
S5: be gradually increased the amount of feeding of spinning wheel and be pointed to the housing of described liner both sides and carry out spinning, and form end cone；
Wherein said end cone radially not contacting with described catalyst converter carrier at described housing.
As further improved technical scheme of the present invention, in step sl, described housing is cylindrically.
As further improved technical scheme of the present invention, described catalyst converter carrier is ceramic monolith.
Present invention further teaches a kind of aftertreatment assembly being made up of above-mentioned method for packing, wherein, described end cone and institute
State the integrated molding of housing.
Compared to prior art, in method for packing of the present invention, process integration completes, and reduces packaging cost, eliminates weldering
It is connected into basis, end cone cost of stamping and longer time cost.Transfer of the prior art being welded to connect to integral type spinning, can be complete
Entirely avoiding the weld strength weakening to endurance life, overall construction intensity and durability are greatly improved.From the point of view of encapsulation, with tradition
Shaping process contrasts, and GBD controls more strict, and the roundness control of spinning back casing is the most accurate, can avoid plastic splint simultaneously
The problem that local shaping is not in place or shaping is excessive that tool tolerance is caused.End cone size and dimension after spinning is all by numerical control
The precision of spinning machine ensures, compares traditional handicraft, and its size and dimension tolerance will significantly increase.It addition, the present invention
Method for packing is simple and convenient, it is only necessary to a spinning machine just can complete the processing and manufacturing of whole system.
Accompanying drawing explanation
Fig. 1 is the section signal after catalyst converter carrier and liner are filled in of the method for packing of catalyst converter carrier of the present invention
Figure.
Fig. 2 is the generalized section that the aftertreatment assembly in Fig. 1 carries out spinning.
Fig. 3 is the generalized section after spinning of the aftertreatment assembly in Fig. 2.
Detailed description of the invention
Please join shown in Fig. 1 to Fig. 3, present invention is disclosed the method for packing of a kind of catalyst converter carrier, it comprises the steps:
S1: the integral housing 1 of a hollow is provided；
S2: liner 2 is provided, and described liner 2 is wrapped on catalyst converter carrier 3；
S3: the described catalyst converter carrier 3 being enclosed with described liner 2 is filled in described housing 1；
S4: utilize the spinning wheel 4 of spinning machine that the housing 1 contacted with described liner 2 is carried out spinning, make described housing 1
Diameter narrowed down to aimed dia D2 by original diameter D1, and the surface pressure produced by compressing described liner 2 keeps institute
State catalyst converter carrier 3 not axial motion inside described housing 1；
S5: by adjusting the spinning degree of depth, the amount of feeding being gradually increased spinning wheel 4 is pointed to the housing 1 of described liner 2 both sides
Carry out spinning, and form end cone 11；Wherein said end cone 11 radially not connecing with described catalyst converter carrier 3 at described housing 1
Touch.
In step sl, cylindrically, common used material is the rustless steels such as 441,409,304 to described housing 1, and thickness is common is
1.2mm or 1.5mm.
Described catalyst converter carrier 3 is ceramic monolith, common for CCC, UFC, DOC, SCR etc..
In step s 4, spinning process needs strictly calculate and control the spinning degree of depth, because in spinning process, liner
2 compression stresses produced can be gradually increased, if spinning excess has the risk that catalyst converter carrier 3 is crushed.
In step s 5, excessive during end cone 11 spinning from housing 1, spinning angle and spinning to strictly be controlled
The position of sudden change, angle should not cross acutely in order to avoid crackle produces, and the position of spinning sudden change simultaneously is strictly forbidden and the region of liner 2
Overlapping.
Please join shown in Fig. 3, the invention still further relates to a kind of aftertreatment assembly 100 formed by above-mentioned method for packing, wherein
Described end cone 11 and the described integrated molding of housing 1.
Compared to prior art, in the method for packing of the present invention, process integration completes, and reduces packaging cost, eliminates
Welding cost, end cone cost of stamping and longer time cost.Transfer of the prior art being welded to connect to integral type spinning, can
Avoiding the weld strength weakening to endurance life completely, overall construction intensity and durability are greatly improved.From the point of view of encapsulation, with biography
System shaping process contrast, GBD controls more strict, and the roundness control of spinning back casing is the most accurate, can avoid shaping simultaneously
The problem that local shaping is not in place or shaping is excessive that Fixture planning is caused.End cone size and dimension after spinning is all by counting
The precision of control spinning machine ensures, comparing traditional handicraft, its size and dimension tolerance will significantly increase.It addition, the present invention
Method for packing simple and convenient, it is only necessary to a spinning machine just can complete the processing and manufacturing of whole system.
It addition, above example be merely to illustrate the present invention and and unrestricted technical scheme described in the invention, to this
The understanding of description should be based on person of ordinary skill in the field, although this specification is with reference to the above embodiments pair
Present invention has been detailed description, but, it will be understood by those within the art that, the technology of art
The present invention still can be modified or equivalent by personnel, and all are without departing from the technology of the spirit and scope of the present invention
Scheme and improvement thereof, all should contain in scope of the presently claimed invention.
