Background technology
Since reform and opening-up, Chinese Auto Industry development is swift and violent, into after the new century, either yield and sales volume, more
It is that explosive growth is presented, after particularly breaking through 18,000,000 to production and marketing in 2010, China has become the vapour of global maximum
Car production and consumption state, the automobile market in China is considered as future development market with the largest potentiality.Automobile industry turns into its people
Economic important pillar industry, form than more complete industrial system, also turned into and embody the significant of national competitiveness
Industry.
Most domestic car enterprise is continuously improving the localization rate of parts and components of auto-parts, is improving the competition of oneself always at present
Power.Although the level of most domestic auto parts and components supplier, it can not still supply the key zero of the high automobile such as benz, BMW
Part and the engine and gearbox for obscuring energy technology, but generally skill level greatly improves, and one not
Holding the trend ignored is, key parts technical ability has progressively shifted to China with market, and at the same time, Chinese automobile parts are
Start to enter into international market on a large scale, and the merger for enthusiastically participating in international automobile fitting industry is integrated.
Now, the production domesticization of auto-parts has begun to crucial spare and accessory parts develop since common spare and accessory parts, from low
End vehicle starts to develop to high-end vehicle.Think to most people in the industry all tendentiousness, as domestic automobile producer adds one after another
The big production domesticization dynamics of local production, drops many times plus domestic automobile price, and to keep profit margin, China of changing the line of production goes forward side by side one
It is clearly the shortcut that can not be detoured that step, which improves the localization rate of parts and components,.
Automobile using steel pipe is an important component of auto-parts, therefore applicant researches and develops be directed to researching and developing always

Change, carry out dog in the ERW feeding head rolling machine after saponification, welded pipe end is rolled to required size；
7）Cold drawing treatment：ERW is sent into drawbench and carries out cold-drawn, during cold-drawn, clamps the termination after pinching processing, together
When mandrel is inserted in welded tube, then make welded tube pass through with tapered minimum-value aperture be less than welded tube external diameter die hole, make welded tube
Inside and outside caliber uniform shrinkage is deformed, and is extended on welded tube length direction, and cold-drawn 1 ~ 3 time is carried out according to different technological requirements,
To obtain required size.
2. the manufacture method of vehicle transmission central siphon as claimed in claim 1, it is characterised in that：The step 1）In coil of strip material

3. the manufacture method of vehicle transmission central siphon as claimed in claim 1, it is characterised in that：The step 2）In, descaling bath
The concentration of middle hydrochloric acid is 120 ~ 160g/L；Flushing temperature in cold rinse bank is 10 ~ 30 DEG C, and flushing pressure is 8 ~ 10kg/cm2；Heat
Temperature is scalded as 90 ~ 100 DEG C in tank；Strip is equal by the speed of descaling bath, the speed of cold rinse bank and hot water storgae and drying
For 30 ~ 40m/ minutes, drying temperature is 100 ~ 120 DEG C.
4. the manufacture method of vehicle transmission central siphon as claimed in claim 1, it is characterised in that：The step 6）In phosphating solution
It is the zinc calcium phosphorization liquid that volumetric concentration is 10 ~ 11%, the temperature of phosphating solution is 65 ~ 75 DEG C, dipping of the ERW in phosphating solution
Time is 25 ~ 30 minutes.
5. the manufacture method of vehicle transmission central siphon as claimed in claim 1, it is characterised in that：The step 6）In saponification liquor
Composition includes lubricant, water and soap powder, wherein, the mass ratio of lubricant and water is 1：（18~20）, soap powder dosage is 50 ~ 60KG/
Ton saponification liquor, saponification liquor temperature are 65 ~ 75 DEG C, and dip time of the ERW in saponification liquor is 10 ~ 25 minutes.
6. the manufacture method of vehicle transmission central siphon as claimed in claim 1, it is characterised in that：The manufacture method also includes table
Face processing step, after cold drawing treatment step, the concrete operations of surface treatment step are surface treatment step：Rust remover is sprayed
Apply and be covered in the surface of ERW, then the surface of ERW is blown with high temperature compressed air, by rust remover
While blowing away, high temperature compressed air dries the rust remover of ERW surface residual, and forming one layer on the surface of welded tube removes
Become rusty agent diaphragm.
