The 2016 New York Auto Show has just ended. At the same time, the world's annual car was also unveiled. Although Mazda won two awards, the “World Wind Car†and the “World's Annual Design,†the author is more concerned with: “World Car of the Year†In the end, the Toyota Mirai, based on the authority of the world's annual car award judges, shows that: Toyota's Mirai has been deeply rooted in people's hearts, the future of hydrogen fuel cell new energy vehicles has been recognized, and industrialization is not as difficult as imagined.
At present, all major countries in the world are strongly promoting the development and popularization of new energy vehicles, and their respective representative brands or models have also been born, and these new representatives are a card for this country in new energy vehicles. For example, when Mirai is in Japan, Tesla is in the United States, BMW i8 is in Germany... What about China? Do we have the brands and models we took?
Some people say that BYD does not allow sales when it comes to sales; others say that SAIC's new energy technologies are the most comprehensive; others say that Black Tech is, of course, my Techrules. In fact, this problem is difficult to answer, because the independent brands are not strong, no car companies have dominance, and each has its own distinct advantages and disadvantages. If you put your perspective on the telecommunications industry, there is no doubt that it is definitely for Huawei, but car companies did not appear "Huawei."
Some time ago a certain guest writer said that the independent brand should not blindly develop pure electric super running. This view is theoretically correct, based on the fact that independent brands do not possess core technologies. The circle of friends circulates a very popular post. The title is “How many core technologies are self-owned brandsâ€. The main contents of the article are the core technologies of gasoline engines, diesel engines, EFIs, transmissions, etc. used by independent brands. The exception is almost always in the hands of foreigners. Therefore, it is natural to conclude;
In fact, I do not agree with the opinion of the guest writer. On the contrary, the writer even promotes the development of new energy sports cars or supercars. First of all, sports cars can enhance brand power. This is precisely the lack of self-owned brands. This is also an important reason why Japanese brands produced luxury brands collectively in the 1980s and 1990s. Similarly, the Korean system is also the same. Because “car†is an exotic product from Europe and the United States after all, the car in the East has a sense of inferiority. In addition, since the inherent attributes of a sports car are high-tech content, it is of significance to the development of the required industrial foundation and the cultivation of talents. Huge; a sports car sometimes even becomes a symbol of a car company or a national endorsement.
Of course, the development of new energy sports cars, our inherent consumption philosophy is the need to change, their own artificial things do not buy themselves how to attract others? Only in this way can a virtuous circle be formed. This article will analyze which models are representative of China's new energy vehicles. First of all, the emphasis is on a few paragraphs, not a certain paragraph, or as mentioned in the previous article, no independent brand in this area to form a dominant force, can not be persuasive.
Branch Pipe, mean pipe fittings tee or tee fittings, tees and the like. It used mainly to change the direction of flow, with a branch in the main conduit to the Office. Can diameter size classification. General carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, pvc and other materials produced.
Casting Branch Pipe is a three hole, namely an inlet and two outlet; or two inlets, a kind of chemical pipe outlet, there are T-shaped and Y-shaped, with equal diameter nozzle, orifice diameter pipe also, for three identical or different line Survey Office. The main role tee is to change the direction of flow.

Divided by the diameter size
1. Tee takeover ends are the same size;
2. Same size - Reducing tee competent to take over, and over size is smaller than the executive branch pipe over size.
Divided by technology
1. hydroforming
Tee hydroforming is compensated by the axial expansion of the metal material of a branch pipe forming process. The process is the use of special hydraulic machine, the injection of the liquid and the inner diameter equal to the three-way tube, side cylinder synchronous movement of the extruded tube by two horizontal hydraulic presses, tube after extrusion by the smaller size, the inner tube the volume of liquid with the smaller tube and pressure rise, when it reaches the three-way manifold pressure required for the expansion, the metal material in the dual role of the cylinder and the inner tube side fluid pressure and flow along the mold cavity bulge manifold.
Tee hydroforming process can be a shape, high production efficiency; competent and shoulder tee wall thickness were increased.
Due to the larger seamless tee hydroforming process equipment required tonnage currently mainly for the manufacture of standard wall thickness less than DN400 tee. Its application for the molding material is relatively low work hardening tendency of low-carbon steel, low alloy steel, stainless steel, including some non-ferrous materials, such as copper, aluminum, and titanium.
2. thermoforming
Thermoforming tee tee is greater than the diameter of the tube, flattening about to tee diameter size,
Stretching branch site to open a hole; tube by heating, into the forming die, and a tensile load manifold die within a tube; tube is radially compressed under pressure, radial compression during the metal flow direction and forming the manifold branch pipe in a stretched punch. The whole process is by radial compression and stretching process tube manifold portion is shaped. Tee hydraulic bulging difference is that hot tee branch pipe metal tube is carried out by radial motion compensation, it is also known as radial compensation process.
Because after pressing tee by heating the material forming the equipment needed to reduce the tonnage. Hot links to wider adaptability of materials suitable for low-carbon steel, alloy steel, stainless steel material; especially large diameter and wall thickness bias tee, often use this forming process.
