Chapter 702

No wonder beck and others were so surprised.

A large-scale equipment more than three meters high is standing in front of people's eyes. Two bright white steel support pillars stand upright like two medieval European knights in iron armor. While supporting the whole equipment, they also fix the large semi-arc skin part with a length of nearly two meters and a width of 1.5 meters in the middle.

If so, it's all right. Both rickelson and Jean Baker have worked in the European aviation industry for half their lives. They haven't seen any large equipment, so they won't be shocked by the three meter high thing in front of them.

The key is that the equipment in front of us is not only huge, but also flexible.

Yes, it's flexible, especially the core processing probe of the equipment. Just like the specially trained human arm, it shakes up, down, left and right in front of the large skin parts, and then starts to perform automatic riveting operation.

Think this is the end?

It's too simple to see this machine. Not only the riveting probe is flexible, but the support frame on both sides can also rotate with the processing of the riveting probe.

With excellent NC program, the whole machine can complete very complex riveting processing in extreme time.

If this is in the United States, rickelson and Jean Baker will not be surprised to see similar equipment. After all, Americans are really unique in the aviation industry. No matter how advanced the equipment is, it is reasonable.

But the problem is that at this moment, the place they are in is called China. In their eyes, there is no place to show off except for a large number of people. It can be called the existence of technological depression. How can they even have such advanced equipment?

You should know that there are only two such large automatic riveting machines, even Airbus. They are all located in the assembly plant in Toulouse, France, and are mainly used for riveting the large radian integral skin parts on the side of A320 fuselage.

With these two devices, Airbus is boasting about its advanced technology and high degree of automation, so as to show potential customers that Airbus's A320 has been imbued with good genes since it was born. You can rest assured that you can buy it boldly.

The reason why we dare to say this is very simple. There are few aviation manufacturing enterprises in the world that can use large-scale automatic riveting equipment, and those who use five axis large-scale automatic riveting equipment have no semicolon except Airbus.

As for whether this kind of five axis large-scale automatic riveting equipment is easy to use, of course, it's hard to say. You should know that the riveting work of traditional large-scale skin parts does not care about other things, just marking this one is enough to make people busy for a while.

Some people asked, what is scribing, its role is similar to the carpenter's ink line, the main role is to set the position of the rivet, because of this, the skin scribing requirements are very high, and must be pure manual, not in this profession for many years the teacher Fu simply can't control.

Even if the semi-automatic riveting equipment appeared later, the manual marking of skin has not been replaced. Instead, it has become an important process of the whole process of semi-automatic riveting equipment, which has become more indispensable.

Because semi-automatic riveting equipment itself is unable to do rivet positioning, only by manually marking out the lines, they can batch riveting processing.

It was not until Germany, relying on its strong R & D capability of mechanical equipment, built a large-scale five axis riveting equipment for Airbus that the manual marking step was completely replaced by machinery under the action of flexible multi axis processing capability and perfect control program.

This is what happened in the past two years. As an overseas OEM base of Boeing, Japan is stepping up the development of similar equipment, which is expected to be put into use in the mid-1990s.

The local aircraft processing plants in the United States have similar equipment, but it is not produced by the United States itself, but imported from the German mechanical equipment company that builds large-scale five axis automatic riveting equipment for Airbus.

For this reason, Airbus obtained a complete set of stress wave riveting technology from the United States, as well as the airworthiness certification of the improved A320 aircraft from the United States Aviation Administration.

However, it is such a kind of important equipment that makes Airbus famous in the world and brings a lot of benefits from the Americans that is now in front of them.

And It seems that They also need to be more flexible, adaptable and have more processing categories.

Because just when they were surprised, the previous 2-meter-long skin part had been processed and replaced with a 1.2-meter-long oblique triangular skin blank, which was obviously something on the wing or tail.

But this is not the point. The key is that the whole equipment has neither replaced the fixture nor redrafted the complex processing procedures. After the hoisting equipment is placed, the riveting probe shakes on it for a moment, and then starts to work like a barrage of bullets. The whole process is full of clouds and water, and there is no meaning of delaying at all.

That's all. What surprised richelsson even more was that when riveting an important part, the original riveting probe suddenly deflected and replaced with a new probe with arm diameter. Then the sound became dull, but the rivets were more than twice as thick as before.

"This is Stress wave riveting? Can also achieve automatic conversion? "When Jean Baker saw this scene, he did not scream, but almost screamed. To know that he got the stress wave riveting equipment from the Americans, Airbus immediately contacted many equipment suppliers and began to study how to apply this technology to the automatic riveting equipment.

After all, Airbus's two large five axis riveting equipment can only do mechanical riveting and pneumatic riveting, but stress wave riveting can't do it at all.

Therefore, when the stress wave riveting process is needed, Airbus has to stop the production of five axis large riveting equipment, remove the parts, and use the most traditional method to complete the stress wave riveting, so as to continue the automatic riveting process.

Because of this, Airbus is eager to integrate stress wave riveting technology into two five axis automatic riveting equipment.

However, European mechanical experts have been working hard for more than half a year, but they have not realized this idea. The reason is very simple. Because of different riveting processes, different quality and specifications of rivets, Airbus can not find a measurement standard and technical scheme that can locate different rivets separately.

In this way, the two five axis automatic riveting machines look very bright. However, with the more and more extensive application of stress wave riveting technology, the two machines in Airbus's hands have gradually become semi-automatic riveting machines. In addition to cheating the media and the public, they only cheat themselves.

Airbus thought that it would take five years for this technical problem to be solved. At the turn of the century, there would be a preliminary result. It was no longer urgent to prepare for a protracted war. Unexpectedly, China's Tengfei group not only solved this problem, but also successfully applied it to actual production. This is really a pity for Jean Baker and others who originally despised Tengfei group It's not shock, it's shock.

So Jean Beck picked up the camera without saying a word. As soon as he was ready to press the shutter, Liu Chun, who was next to him, said slowly in English with a strong Shanghai accent: "a photo costs US $5 million. After all, we are not Boeing, so it doesn't matter how you copy it. Our small business of Tengfei group can't stand your unscrupulous copying. What's more, you are Airbus What powerful enterprise, can you still see our things? How shameful it is to be heard ~ ~ "

in a word, Jean Beckton, who was ready to press the shutter, froze there, and his old face turned red with shame!
