Yes, it is technology crushing!

Because the technology used by China Ascendas to produce the 6MAX mid-section wing body fusion body can be summed up in two words: stamping!

Of course, stamping in the aerospace manufacturing field can be different from ordinary stamping. No matter the material, the process, or the difficulty is not on the same level.

Not to mention anything else, just take the largest closed equipment on the production line. If Barotov is right, it should be an integrated equipment that integrates heat treatment and primary stamping.

Needless to say, stamping, the key is the heat treatment step. What is used is not a simple heat treatment, but a new technology called warm forming.

Related studies have found that the ductility and stretchability of metals at a certain temperature between room temperature and crystal recrystallization will increase exponentially, thereby increasing the utilization rate of metal materials, thereby reducing costs and improving efficiency.

For example, ordinary aluminum alloy, at a temperature of 280 degrees Celsius, the ductility increases from 20% of normal temperature to 80%.

Because of this, since the advent of warm forming technology, it has become highly efficient sheet metal parts. The high utilization rate is favored by almost all industries such as aerospace, automobile manufacturing, shipbuilding and machinery manufacturing.

Especially in aerospace, the metal materials used are either rich or expensive. If the utilization rate can be increased by 10%, the cost savings will be considerable, let alone an increase of more than 50%.

The question is whether the isothermal forming technology is good or not, and the principle is not difficult, but there is a difficult problem that no one can avoid, that is, what is the best elongation temperature for processing metal materials. If this value cannot be determined, even if there is warm forming The equipment can't make the most efficient metal sheet metal extensions, not to mention, but it will backfire, resulting in an increase in the scrap rate.

A few years ago, South Korea suffered from this loss and felt that it was good enough. The scholars and European and American giants also purchased a special warm forming and stamping equipment for aerospace and aerospace.

As a result, it was found that after using the equipment with excellent results in European and American manufacturers, it was the same as inadmissibility in South Korea when the equipment was tried by European and American manufacturers. South Korea could not produce qualified products at all. So South Korea filed a complaint with European and American manufacturers.

After a visit from European and American manufacturers, the response they gave almost caused South Korea to collapse.

The money you buy for the equipment is only enough for stamping with ordinary materials such as low-carbon steel. If you want to make stamping parts of aluminum alloy, aluminum-lithium alloy, and even titanium alloy, I'm sorry, a set of data will cost at least 18 million U.S. dollars.

That's not to mention, all data upgrades are handled by the personnel of European and American manufacturers, and South Korea must not be present. In addition, the South Korean manufacturers will have to pay a maintenance fee of 5 million US dollars each year to complete the data upgrade. If there is further upgrade, it needs to be recalculated.

In other words, the equipment belongs to South Korea, but the soul belongs to the European and American manufacturers. South Korea is a tool man at best. It costs money and gets tired. In the end, you have to let European and American manufacturers use all kinds of white scoops. Still changing the white scoop in different poses.

South Koreans are depressed and want to vomit blood, but they have no choice but to reinvest huge sums of money to upgrade the equipment data. There is no way. Whoever allows European and American aviation access to include certain warm-formed stamping parts as safety standards, you do not follow up Not even the qualifications to integrate into the human industry chain.

Therefore, even if it was taken as a victim and slaughtered, it would be recognized.

South Korea is pretty good, most other European and American manufacturers can swipe down with butcher knives when they scratch their heads.

Russia doesn't have this blessing. Even if the neck is cleaned and let European and American manufacturers kill, people don't bother to take the knife.

Yes, even if Russia recognizes the slaughter, European and American manufacturers will not sell similar equipment to Russia, let alone the precious data behind such equipment.

In fact, the Soviet Union is not weak in the study of sheet metal forming technology and metal materials, otherwise it will not make such brilliant achievements in the aerospace field. However, the disintegration of the Soviet Union suddenly disrupted the original scientific research plans and industrial division of labor, leading to Russia’s This has plummeted.

Warm forming is a brand-new subject in the field of sheet metal forming. Although the Soviet Union has dabbled in it, it has not yet made the progress it deserves. The Soviet Union collapsed. In addition, after the disintegration, Russia’s various economic tossings directly destroyed itself. I was crippled, and after looking back, I wanted to chase, but found that Russia was still the same Russia, but the world was not that world anymore.

The gap was opened instantly!

Then...then the European and American manufacturers collectively watched the tweaked Teddy Bear shaking his body in an awkward manner, begging for someone to kneel and lick, laughing as if watching a comedy.

The humiliated bear had no choice but to silently return to his tree hole to lick his injured self-esteem.

However, this is not the key, the most deadly is the proud production capacity and violent soldiers of the Soviet era, which became insignificant due to the lack of thermoforming technology.

After all, the efficiency of a large number of stamping parts cannot be filled by the old Soviet-style factories.

And this is just the pediatrics of many high-tech in this set of automated sheet metal forming production lines in China. What really turns decadence into a miracle is the equipment that integrates horizontal and vertical stretching; multi-point precise stretching; and complex curved surface stamping and forming.

It can be said that without this equipment, the wing-body fusion is simply not integrated, and China Ascendas will not be able to reduce its own manufacturing costs, and there will be no so-called manufacturing revolution.

Because this equipment uses moldless molding technology that is more difficult than warm molding and has a higher degree of automation.

The biggest advantage of this technology is that it can stamp and form complex curved structures at one time without the need for follow-up and processing.

For some aviation components that require metal materials and are not too complex in structure, but require complex curved surfaces, it can be described as an artifact to reduce costs and improve efficiency.

The reason for saying this is very simple. The most important feature of moldless forming is that it does not require special stamping dies.

It should be known that in the field of sheet metal forming, the cost of molds can account for 30% to 50% of the total manufacturing cost; even the cost of some special shaped molds can reach the total cost of ~www.readwn.com~, while the moldless molding technology will The biggest cost source in sheet metal forming is directly removed. Since then, no mold is needed, and sheet metal can be stretched and stamped as needed.

This technology is only mastered by the United States and the United Kingdom in the world.

The reason is simple, because this technology is based on the flexible tooling system in the aerospace field. Without the support of this technology, moldless molding is like water without a source and a tree without roots. It simply won't work.

In fact, Russia has already made great efforts in moldless forming technology, but Russia's technology on the flexible tooling system is not good enough, so the moldless forming stamping equipment made is naturally full of loopholes.

As a result, the flatness of the sheet metal parts is particularly poor, and the overall craftsmanship is worrying.

Barotov still knows this very well. That's why he was surprised to be speechless when he saw this automated sheet metal forming production line, but once he recovered, he was as excited as seeing a baby. As a result, I didn’t ask other details at all, and went straight to the subject: “Mr. Zhuang, I don’t know how much this sheet metal production line sells?”

"Not expensive!" Zhuang Jianye replied simply: "It's only 800 million US dollars!"
