Abstract
The utility model discloses an exhaust pipe, comprising an exhaust pipe body (1), wherein a curled edge (2) which bends inwards to the pipe body is arranged on the outlet end of the exhaust pipe body (1). The curled edge (2) is integrally formed with the exhaust pipe body (1). The exhaust pipe disclosed by the utility model has the capability of effectively improving the strength of the exhaust pipe body, especially the strength of the outlet end of the exhaust pipe body; and wall thickness is unnecessary to increase, so that the production cost is lowered to a certain degree.
Description
Technical field:
The utility model relates to a kind of body that is used to discharge automobile exhaust gas, specifically is a kind of outlet pipe.
Background technique:
Outlet pipe also is tailpipe, is used to discharge automobile exhaust gas.In discharge process, higher and have certain impact force because of the exhaust gas discharged temperature, so in the design process of outlet pipe, the intensity of outlet pipe, the especially intensity of exhaust outlet end seem particularly important.
At present, generally improve the intensity of outlet pipe through the method that increases the outlet pipe wall thickness, but along with the increase of thickness, the also corresponding increase of cost of production.
The model utility content:
The utility model technical issues that need to address are: the outlet pipe that a kind of intensity effectively improves and cost of production is relatively low is provided.
For solving the problems of the technologies described above, the utility model adopts a kind of like this outlet pipe, and it comprises exhaust pipe, and the outlet end of described exhaust pipe is provided with crimping crooked in body.
Described crimping and exhaust pipe are one-body molded.
The utility model compared with prior art; Have the following advantages: owing to be provided with crimping crooked in body at the outlet end of exhaust pipe; This crimping be arranged on the intensity that has effectively improved exhaust pipe under the prerequisite that does not increase the exhaust pipe wall thickness; Especially the intensity of exhaust pipe outlet end, and exhaust pipe wall thickness need not to increase, and has compared with prior art reduced cost of production.
As improvement, described crimping and exhaust pipe are one-body molded, have further improved the intensity of exhaust pipe.
Description of drawings:
Fig. 1 is the structural representation of the outlet pipe of the utility model.
Fig. 2 is the sectional structure schematic representation of the outlet pipe of the utility model.
Shown in the figure: 1, exhaust pipe, 2, crimping.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, the outlet pipe of the utility model, it comprises exhaust pipe 1, the outlet end of described exhaust pipe 1 is provided with crimping 2 crooked in body.
In the present embodiment, as shown in Figure 2, described crimping 2 is one-body molded with exhaust pipe 1, and the outlet end that is to say exhaust pipe 1 is through the interior crimping that rolled to forming, and crimping is provided with effective intensity of strengthening exhaust pipe in this.For the intensity of the outlet end that makes exhaust pipe 1 is further enhanced the cross section semicircular in shape of this crimping 2.
Claims (2)
1. outlet pipe, it comprises exhaust pipe (1), it is characterized in that, the outlet end of described exhaust pipe (1) is provided with crimping (2) crooked in body.
2. outlet pipe according to claim 1 is characterized in that: described crimping (2) is one-body molded with exhaust pipe (1).
