Abstract
A kind of fixed flange of automobile exhaust pipe linking, its middle part opens up blast pipe mounting hole, and the both sides of blast pipe mounting hole open up flange connecting hole, blast pipe installation hole flanging, the outward flange flange of flange, the flange direction of blast pipe mounting hole are same as the outer peripheral flange direction of flange.Flange described in the utility model, formed by a sheet material through punching, flange, shaping, its structural stability is preferable, and surface finishing.
Description
Technical field
The utility model belongs to auto parts machinery, and in particular to the flange of blast pipe.
Background technology
Flange, it is a kind of connector of extensive utilization.Whole automobile exhaust pipe is to connect some sections of exhausts by flange
Manage and be molded, specifically, adjacent two sections of blast pipes are connected by the connection of two flanges thereon.Wherein, either segment is vented
Mounting hole is opened up on the flange of pipe, is combined with threaded fastener in mounting hole, two flanges on adjacent two sections of blast pipes pass through
Threaded fastener connects.And the blast pipe is plugged in the blast pipe mounting hole of flange, the blast pipe mounting hole is typically opened
It is located at the middle part of flange.
Utility model content
The technical problem that the utility model solves：How firmness that blast pipe with flange be connected is improved.
In order to solve the above technical problems, the utility model provides following technical scheme：A kind of automobile exhaust pipe linking is fixed
Flange, its middle part open up blast pipe mounting hole, and the both sides of blast pipe mounting hole open up flange connecting hole, and flange connecting hole is set
There is first annular flange, first annular flange is connected with rigid posts, and the rigid posts are located in the second annular flange, and described
Second ring flange is arranged on around blast pipe mounting hole.
Two flanges on adjacent two sections of blast pipes are connected by threaded fastener, wherein, threaded fastener preferably coordinates
The screw bolt and nut used, bolt head and nut are close on flange, to reach the effect of two flanges of connection.In bolt head
Or nut is close and during being close on flange, bolt head or nut strut first annular flange, first annular flange footpath
To rigid posts are promoted, the other end of rigid posts protrudes the madial wall of the second annular flange and stretches into the inner ring of the second annular flange
In, it is pressed on the lateral wall of blast pipe, to fasten the connection of blast pipe and flange, wherein, the blast pipe is plugged in exhaust
In pipe mounting hole.
The madial wall of first annular flange is connected in cone, rigid posts with the lateral wall of first annular flange, rigid posts
Perpendicular to the hole heart line of flange connecting hole.The madial wall of first annular flange facilitates bolt head or nut progressively to support in cone
Open first annular flange.
Rib is provided between first annular flange and the second annular flange, the rigid posts are located in rib, rib it is hard
Hardness of the degree less than rigid posts.When the first annular flange driving rigid posts outwards strutted move radially, rib is squeezed deformation.
Second annular flange is formed by blast pipe installation hole flanging；The outward flange flange of flange.Blast pipe mounting hole
Flange direction be same as the outer peripheral flange direction of flange.
Flange described in the utility model, being formed by a sheet material through punching, flange, shaping, its structural stability is preferable, and
Surface finishing.

Embodiment
Referring to figs. 1 to Fig. 3, a kind of fixed flange of automobile exhaust pipe linking, its middle part opens up blast pipe mounting hole 10,
The both sides of blast pipe mounting hole open up flange connecting hole 20.
The second annular flange 50 is provided with around blast pipe mounting hole 10.
First annular flange 30 is provided with around flange connecting hole.
The outward flange flange of flange.
Rib 60 is provided between the first annular annular flange 50 of flange 30 and second, rigid posts 40 are embedded with rib.Firmly
One end of matter bar is connected with first annular flange, and the other end is located in the second annular flange 50.Wherein, the hardness of rib is less than
The hardness of rigid posts.
The madial wall of first annular flange 30 is connected in cone, rigid posts 40 with the lateral wall of first annular flange, firmly
Hole heart line of the matter bar perpendicular to flange connecting hole 20.
In production, cut technique, the sheet material of one flange of lower processing is cut out from bulk plate, sheet material is punched out, is rushed
Blast pipe installation initial apertures (internal diameter is less than blast pipe mounting hole 10), the blast pipe installation initial apertures gone out in the middle part of flange
The flange connecting hole 20 of both sides.Afterwards, punching press is carried out with initial apertures to the blast pipe installation using hardware dies, makes its edge
Turn up, form flange, while be molded blast pipe mounting hole 10；The hardware dies carry out punching press to the outward flange of flange, make method
Blue outward flange is in flange shape.Afterwards, shaping is carried out to flange, mainly the outside of the flange to blast pipe mounting hole 10 and flange
Edge flange carries out shaping, to complete the production of flange.
Above content is only better embodiment of the present utility model, for one of ordinary skill in the art, according to this
The thought of utility model, there will be changes, this specification content should not be understood in specific embodiments and applications
For to limitation of the present utility model.
