With the cross sectional shape of air inlet pipe back segment 3 can it is identical can not also be identical.By above technical scheme, have caused by the present invention
Beneficial effect is：
By the way that mounting ring is arranged in rational position, and former mounting ring is improved to from monocycle bicyclic, preferably realized
The needs of the installation and connection sealing of automotive air intake pipe and other component, bicyclic mounting ring can effectively ensure interstructural gas
Close property reduces damage of the high-temperature fuel gas to other component；Meanwhile mounting ring moulding process by it is original welding be changed to one at
Type enhances the structural stability of mounting ring segments, less easy to fall off, during automobile bumpiness traveling and long run, no
But macrocyclic alternating load environment can be coped with, more can preferably keep connecting under high temperature environment, be effectively guaranteed riding
The safety of vehicle personnel.
The pipeline of different angle in automotive air intake pipe is needed, ground is distinguished and uses two kinds of techniques of bending and welding, it is smaller
Angle is used with pipe bending technique, and the continuity and integrality of structure is effectively ensured, and one-pass molding reduces process time cost, essence
True angle control；Different tube welding process is then used compared with mitre, so that the tube wall of titanium alloy material is unlikely to because crossing wide-angle
Bending stretches and area of section is caused to reduce, and reduces processing scrappage, improves production efficiency.
Automotive air intake inside pipe wall is polished, and is not only made polished air intake duct surface smooth, is effectively reduced intake resistance,
It reduces when air flows through air flue the phenomenon that airway surface generates stagnation；And increase gas port after so that automotive air intake pipe is polished
Diameter, the flow conductance and heat for being conducive to automotive air intake pipe are conducted.
The cross sectional shape for reasonably selecting automotive air intake pipe, is allowed to adapt to the automobile of different model, and product is made to have centainly
The colleague of structural strength has wider market value.
Specifically：The innovative point of the present invention is mostly closed with silica gel, aluminium for the material of current automotive air intake pipe in the market
Based on golden material, being easy aging deformation can not take into account with lightweight, the problems such as product quality is coarse, and consistency is poor.Using intensity
More preferably, lighter and corrosion-resistant and high-temperature resistant the titanium alloy material of quality is as product material.
Silica gel material automotive air intake pipe is easy aging cracking deformation, and non-refractory, perishable；And aluminum alloy material
Automobile repacking product, though quality is light, insufficient strength is easy breakage.The automobile repacking product of more traditional material, this project titanium close
Golden automotive air intake pipe technological transformation project advantage is：From product advantage, using the titanium that intensity is high, thermal diffusivity is good, quality is small
Alloy material is made, inner wall smooth, will not deform easily, is inhaled into cylinder with enabling inlet air flow fast and stable.Titanium or titanium alloy
Material possesses the characteristics of lightweight and high intensity, under the premise of protecting and improving the safety and performance of repacking vehicle, keeps vehicle body light
Quantization.
Simultaneously in the process for assembling and welding stage of product key, assembly welding is carried out using intelligence machine, improves production
Efficiency simplifies operating personnel, is that titanium alloy automobile repacking part Product Precision and its consistency increase substantially, while reducing energy
Consumption.By the technology upgrading replacement to product material, the automatic assembly welding of intelligent robot, product qualification rate greatly improves, titanium
Alloy automobile reequips part precision and consistency meets or exceeds domestic and international same car repacking Product Level.
Air inlet pipe is to connect the device of air cleaner and inlet manifold, and the repacking of air inlet pipe mainly solves following three sides
Face problem：
1) air inlet inside pipe wall polishes
Naturally aspirated engine is the pull of vacuum by descent of piston, and rush admits air into combustor inner cylinder, passive suction
Gas efficiency can not show a candle to increase system；In order to increase air inlet rate, inlet channel is bigger, it is more smooth better.But producer produce in batches into
When tracheae, it is contemplated that cost factor, it is impossible to which fine to be particular about, inevitably some are rough.In order to handle these problems, need
Air inlet inside pipe wall is polished using grinding equipment.
The effect of air inlet inside pipe wall polishing can be divided into 2 aspects：First, polished air intake duct surface is smooth, can effectively drop
Low intake resistance is reduced when air flows through air flue the phenomenon that airway surface generates stagnation；Second is that can moderately increase gas after polishing
Road bore, the amplitude increased in this way is not very big, can be considered caused added benefit after polishing.
2) air inlet pipe cross sectional shape is reequiped
The shape of air inlet tube section substantially has 3 kinds of the rectangle of rectangle, circle and rounded corner.The shape of air inlet pipe is to air inlet
Efficiency has a certain impact, and under various operating modes, the intake efficiency of the rectangular-section pipeline of rounded corner is preferable.The shape of air inlet pipe
It should be as possible consistent with the shape of the air inlet pipe of original engine, the sectional area of air inlet pipe should be consistent with original.Air inlet pipe
Length should take into account the application of endotracheal dynamic effect.
3) air inlet pipe material is reequiped
The material of air inlet pipe is considered as heat absorption less and quality is small, and the air inlet pipe of general vehicle is all by softer primary of quality
Forming plastic cement material is made, and this kind of the cost of material is low, and convenient for producing in enormous quantities, but plastic material is easy to generate aging cracking
Phenomenon.Aluminium alloy is easy high temperature deformation again.Titanium alloy material good heat dissipation, high temperature resistant, the advantages that being unlikely to deform.
Automobile dynamic system inlet manifold is manufactured with metal.It is complex-shaped due to manifold, it was to use in the past
Aluminium alloy casting, but inner wall coarse, when use, is very big to the resistance of air, and noise is big, causes to burn insufficient, exhaust gas discharge
It is more.In the last century 80's, Europe starts with losing core autofrettage (CoreMelt), so-formed manifold not only cost
Height, and have certain rejection rate because the material PA66 (or PA6) of manifold is after fiberglass reinforced, processing temperature 250 to
260 DEG C, although in only a few minutes time of contact of Mo Nei and core, part core is also inevitably melted, and manifold is made
Inner wall size be difficult to be controlled.Still have at a high temperature of bearing 220 DEG C at work due to the part requirements on engine periphery
High-modulus, high intensity still have good mechanical performance and the toughness without fragmentation at -40 DEG C, for glass fiber enhanced nylon, silicon
It has not been classic material for glue, aluminium alloy.
It is considered from automotive air intake pipe material lifetime, market competition, automobile are active etc., titanium alloy material air inlet pipe is at this
Several aspects are all evaded.First, under equal conditions, titanium alloy material inner wall is more smooth, reduces windage, keeps air better
Into promoting fully to burn；High-temperature corrosion resistance increases life of product again, economic and environment-friendly；Finally, quality is light and handy, and flexible can be with
The good characteristics such as stretching.It is one to vehicle power hoisting that titanium alloy air inlet pipe quality is light and handy, inner wall smooth reduces the factors such as empty resistance
A no small promotion.
