Take Off My Aviation Era

No wonder that Baker and others were so surprised.

I saw a large equipment over three meters high standing in front of everyone. The two bright white steel support pillars stood proudly just like two European medieval armored knights. While supporting the entire equipment, they also Fix the middle piece of semi-arc-shaped large skin part with a length of nearly 2 meters and a width of 1.5 meters.

If this is the case, whether it is Rickelson or Jean Baker, they are people who have worked in the European aviation industry for half their lives. I have not seen any large-scale equipment, so I will not be surprised by the three-meter-high thing in front of me. Almost dropped his chin.

The key is that the equipment in front of you is not only huge, but more importantly flexible.

That's right, it is flexible, especially the core processing probe of the equipment, just like a specially trained human arm, it swayed up and down against the large skin part in front of it, and then began to bang~~ for automated riveting operations.

Think this is over?

Then look at this machine too simple. Not only is the riveting probe flexible, but the support frame on both sides can also be rotated along with the processing of the riveting probe.

With excellent CNC programs, the whole equipment can complete very complex riveting processing in extreme time.

If this is in the United States, people like Rickelson and Jean Baker would not be surprised to see similar equipment. After all, Americans are really the best in the aviation industry, and the advanced equipment is reasonable. .

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

You should know that even Airbus has only two such large-scale automatic riveting machines, all of which are located in the final assembly plant in Toulouse, France, and are mainly used for riveting processing of large-curved integral skin parts on the side of the a320 fuselage.

It is precisely with these two devices that Airbus brags about how advanced their technology is and how high the degree of automation is, in order to show potential customers that the Airbus a320 has been instilled with good genes, you Feel free to buy and you are done.

The reason why I dare to say so is very simple. There are really few aviation manufacturing companies that can use large-scale automatic riveting equipment in the world, and there are no semicolons except Airbus that use large-scale automatic riveting equipment with five-axis.

As for whether this five-axis large-scale automatic riveting equipment is good or not, it is natural to say that the riveting work of the traditional large-scale skin parts is still a matter of fact, and the scribing alone is enough for people to work for a while.

Someone asked, what is marking, its function is similar to that of a carpenter's ink line. The main function is to position the rivets. Because of this, the requirements for skin marking are very high, and it must be purely handmade, not in this line. Masters who have been working for many years simply can't control it.

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

Because the semi-automatic riveting equipment itself cannot do rivet positioning, it can only manually mark out the ministries that have been marked so that they can be riveted in batches.

It was not until Germany developed a five-axis large-scale riveting equipment tailored for Airbus with its own strong R&D capabilities in mechanical equipment. The manual marking step was completely replaced by machinery under the action of flexible multi-axis processing capabilities and complete control procedures. .

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

The aircraft processing plants in the United States have similar equipment, but they are not produced by the United States, but imported from the German machinery company that builds large-scale five-axis riveting equipment for Airbus.

For this reason, Airbus obtained a full set of stress wave riveting technology from the United States, as well as the airworthiness certification of the American Aviation Administration of the improved a320 aircraft.

However, it is this kind of important equipment that has made Airbus famous in the world and has brought many benefits from the Americans, and it is in front of them at this moment.

And... it seems... more flexible, more adaptable, and more processed than theirs.

Because just when they were surprised, the previous 2-meter-long skin part had been processed. The replacement was not a blank of the same category, but a 1.2-meter-long diagonal triangle skin blank, which was obviously a wing. Or something on the rear wing.

But this is not the point. The key is that the whole equipment neither changed the fixture nor re-edited the complicated processing procedures. It just used the hoisting equipment to set it up, and the riveting probe was shaken on it for a while and then it started booming like a bead. Work, the whole process went smoothly, and there was no point in delaying.

That's all. What made Rickelson even more surprised was that when riveting an important part, the original riveting probe suddenly deflected and replaced it with a brand new probe with a thick arm. Then the sound became dull, but the sound went in. The rivet is more than twice as thick as before.

"This is... stress wave riveting? Can also be fully automated?"

When Jean Baker saw this scene, he was no longer exclaimed, but almost roared. To know that the stress wave riveting equipment was obtained from the Americans, Airbus immediately contacted many equipment suppliers and began to study how to apply this technology to Fully automatic riveting equipment.

After all, the two large five-axis riveting equipment of Airbus can only be used for mechanical riveting and pneumatic riveting, but stress wave riveting is impossible.

Therefore, when the stress wave riveting process was required, Airbus had to stop the production of the five-axis large-scale riveting equipment, remove the parts, and use the most traditional method to complete the stress wave riveting process in order to continue the automated riveting process.

Because of this, Airbus really wants to integrate the stress wave riveting technology into two five-axis automatic riveting equipment.

However, European mechanical experts have not realized this idea for more than half a year~www.readwn.com~ The reason is simple, because the riveting process is different, the quality and specifications of the rivets are different, and Airbus can’t find one that can locate different rivets separately. Measurement standards and technical solutions.

As a result, the two five-axis automatic riveting equipment looks very glamorous, but as the stress wave riveting process becomes more and more widely used, the two equipment in Airbus's hands are gradually reduced to semi-automatic riveting machines. The media and the public are left with self-deception.

Airbus originally thought that it would take five years for this technical problem to be a little more eye-catching, and that there could be preliminary results at the turn of the century, so it was no longer eager and prepared to fight a protracted war. As a result, it never expected that China's Ascendas Group would not only solve it. This problem has been successfully applied to actual production. For Jean Baker and others who could not look at Ascendas Group, it is really not shocking, but shocking.

So Jean Baker picked up the camera without saying a word. Just as he was about to press the shutter, he listened to Liu Chun next to him slowly saying in English with a strong Shanghai accent: "A photo is five million dollars. After all, we are not Boeing. It doesn't matter how you copy it. Our Ascendas Group has a small business and cannot withstand your unscrupulous copying work. Besides, your Airbus company, which is such a powerful company, can still see our stuff? How shameful it is to spread it out. ~~"

In a word, Jean Baker, who was about to press the shutter, suddenly froze there, and his old face was blushing!
