Description
Technical field
Field, more particularly to a kind of manufacture method of integrated car blast pipe are manufactured the present invention relates to automobile exhaust pipe.
Background technology
At present, automobile exhaust pipe includes the first section of jurisdiction and the second section of jurisdiction, and first section of jurisdiction and the second section of jurisdiction surround tubulose
Blast pipe, is then welded the edge that the first section of jurisdiction and the second section of jurisdiction connect by welding machine, simple to operate, quick.
But this blast pipe mode of production, blast pipe is influenceed very huge by welding procedure, if welding procedure is poor, the
Easily there is gap in one section of jurisdiction and the second section of jurisdiction the edge welding raw weld seam of practicing midwifery that connects, cause blast pipe light leak or produce abnormal sound,
The practicality and using effect of serious reduction blast pipe.
The content of the invention
It is an object of the invention to overcome the deficiency that above-mentioned prior art is present, and provide a kind of integration, not light leak and
The all-in-one car blast pipe of simple production process.
The object of the present invention is achieved like this.
The manufacture method of integrated car blast pipe, comprises the following steps：
A：Steel plate is cut, the first section of jurisdiction and the second section of jurisdiction is cut out；
B：The bending of first section of jurisdiction is U-shaped, the second section of jurisdiction is bent U-shaped；
C：First section of jurisdiction and the second section of jurisdiction are surrounded into blast pipe, the edge that the first section of jurisdiction of welding and the second section of jurisdiction connect；
D：First section of jurisdiction and the second section of jurisdiction the edge welding raw weld seam of practicing midwifery that connects are flattened；
E：Blast pipe is flattened into the rhombus blast pipe of flat；
F：The rhombus blast pipe of flat is subjected to enlarging and swollen type, the rhombus blast pipe of stereo structure is formed it into；
G：Blast pipe is subjected to trimming, blast pipe shape is repaired；
H：Blast pipe is subjected to annealing operation, increases the intensity of blast pipe；
I：Step is expanded in the side entrance of blast pipe one, then extruding the body of blast pipe makes its produce concave station；
J：Blast pipe is subjected to cleaning and removes superficial stain, then toward one layer of protective paint of its surface spraying.
Beneficial effects of the present invention are as follows：
Of the invention first section of jurisdiction and the second section of jurisdiction surround blast pipe, and the first section of jurisdiction and the second section of jurisdiction edge welding that connects are practiced midwifery raw weldering
Seam, weld seam handles the gap for having filled up commissure by pressing, makes the first section of jurisdiction and the second section of jurisdiction integrator, makes blast pipe more
Globality more preferably, improves the practicality of integrated exhaust pipe.
Further, the side entrance of blast pipe one is provided with step, by setting step to be easy to blast pipe to position and install, Er Qiepai
One layer of protective paint of tracheae surface spraying, effectively prevents blast pipe to be corroded, and improves the service life of blast pipe.

Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
Embodiment, with reference to shown in Fig. 1 to Fig. 6, the manufacture method of integrated car blast pipe comprises the following steps：
A：Steel plate is cut, the first section of jurisdiction 1 and the second section of jurisdiction 2 is cut out；
B：First section of jurisdiction 1 is bent U-shaped, the second section of jurisdiction 2 bent U-shaped；
C：First section of jurisdiction 1 and the second section of jurisdiction 2 are surrounded into blast pipe 3, the first section of jurisdiction 1 of welding and the 2nd 2 edge connected；
D：First section of jurisdiction 1 and the second section of jurisdiction 2 weld seam 4 that edge welding practices midwifery raw that connects are flattened；
E：Blast pipe 3 is flattened into the rhombus blast pipe of flat；
F：The rhombus blast pipe of flat is subjected to enlarging and swollen type, the rhombus blast pipe of stereo structure is formed it into；
G：Blast pipe 3 is subjected to trimming, the shape of blast pipe 3 is repaired；
H：Blast pipe 3 is subjected to annealing operation, increases the intensity of blast pipe 3；
I：Step 5 is expanded in the side entrance of blast pipe 3 one, then extruding the body of blast pipe 3 makes its produce concave station 6；
J：Blast pipe 3 is subjected to cleaning and removes superficial stain, then toward one layer of protective paint 7 of its surface spraying.
Of the invention first section of jurisdiction 1 and the second section of jurisdiction 2 surround blast pipe 3, and the first section of jurisdiction 1 and the second section of jurisdiction 2 connect edge welding
Practice midwifery raw weld seam 4, weld seam 4 handles the gap filled up at weld seam 4 by pressing, makes the first section of jurisdiction 1 and the second section of jurisdiction 2-in-1 into one
Body, makes the more globality of blast pipe 3 more preferably, improves the practicality of integrated exhaust pipe.
Further, the side entrance of blast pipe 3 one is provided with step 5, by setting step 5 to be easy to blast pipe 3 to position and install, and
And blast pipe 3 surface spraying, one layer of protective paint 7, effectively prevent blast pipe 3 to be corroded, improve the service life of blast pipe 3.
