It's no wonder that Jean Baker and others were so surprised.

I saw a large equipment more than three meters high standing in front of everyone's eyes, two bright white steel support columns, like two European medieval ironclad knights standing proudly upright, while supporting the entire equipment, but also fixing the middle piece of nearly 2 meters in length, 1.5 meters wide semi-arc large skin parts.

If that's the case, whether it's Rickerson or Jean Beck, both of whom have worked in the European aviation industry for half their lives, have never seen any large equipment, so they won't be so shocked by the three-meter-tall thing in front of them that their jaws almost dropped.

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 processing probe at the core of the equipment, just like a specially trained human arm, shaking up and down left and right on the large skin parts in front of you, and then starting to bang ~~ for automatic riveting operations.

Think that's the end of it?

Then this machine is too simple, not only the riveted probe is flexible, but the support frames on both sides can also be rotated with the processing of the riveted probe.

Combined with the excellent CNC program, the entire machine can complete very complex riveting processes in extreme time.

If this is in the United States, Rickelsson and Jean Baker and others will not be surprised to see similar equipment, after all, the Americans are really unbeatable in the aviation industry, and it is reasonable that the equipment is advanced.

But the problem is that at this moment, the place where they are is called China, a place where they have nothing to show off except for the number of people, the existence of a technological depression, and there is such advanced equipment?

You must know that even Airbus has only two large-scale automatic automatic riveting machines, all of which are located in the final assembly plant in Toulouse, France, and are mainly used for riveting the large-arc integral skin parts on the side of the A320 fuselage.

It is with these two pieces of equipment that Airbus has boasted about how advanced their technology is and how high the degree of automation is, so as to show potential customers that Airbus's A320 has been instilled with good genes in the womb, and you can buy it boldly and be done.

The reason why I dare to say this is very simple, there are really few aviation manufacturers in the world who can use large-scale automatic riveting equipment, and there is no semicolon except Airbus for five-axis large-scale automatic riveting equipment.

As for whether this five-axis large-scale automatic riveting equipment is good or not, naturally there is nothing to say, you must know that the riveting work of traditional large-scale skin parts does not matter what else, just the marking is enough for people to be busy for a while.

Someone asked, what is the marking, 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 marking requirements are very high, and it must be purely manual, not in this industry for many years of the master can not control at all.

Even if the semi-automatic riveting equipment appeared later, the manual marking of the skin was still not replaced, but became an important process of the whole process of the semi-automatic riveting equipment, and became more indispensable.

Because the semi-automatic riveting equipment itself is unable to do rivet positioning, it can only rely on manual marking of the marking ministries and commissions, and they can be riveted in batches.

It was not until Germany later relied on its strong mechanical equipment research and development capabilities to tailor a five-axis large-scale riveting equipment for Airbus, and the manual marking step was completely replaced by machinery under the effect of flexible multi-axis machining capabilities and perfect control procedures.

This is also a matter of the past two years, Japan, as the overseas foundry base of Boeing of the United States, is stepping up the development of similar equipment, which is expected to be put into use in the mid-90s.

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

To this end, Airbus obtained a full range of stress wave riveting technologies from the United States, as well as airworthiness certification from the U.S. Aviation Administration for the improved A320 airliner.

However, it is such an important equipment that has made Airbus famous all over the world and has received a lot of benefits from the Americans, which is now in front of them.

And...... Seem...... It is also 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, and it was replaced with a 1.2-meter-long oblique triangle skin blank that was not of the same type, but a 1.2-meter-long oblique triangle skin blank, which was obviously something on the wing or tail.

But this is not the point, the key is that the whole equipment neither replaced the fixture, nor re-programmed the complex processing procedures, but the use of hoisting equipment to place it, the riveting probe shook on it for a while, and then even the beads like a bang ~~~ began to work, the whole process is smooth, and there is no meaning of delay.

That's it, what surprised Rickelsson even more was that when riveting an important part, the original riveting probe suddenly deflected and replaced with a new probe with the thickness of an arm, and then the sound became muffled, but the rivet that entered it was more than twice as thick as before.

"It's ...... Stress wave riveting can also be fully automated?"

Jean Baker was not exclaimed when he saw this scene, but almost roared, knowing 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 fully automatic riveting equipment.

After all, Airbus's two five-axis large riveting equipment can only do mechanical riveting and pneumatic riveting, and stress wave riveting cannot be done at all.

Therefore, when the stress wave riveting process is required, Airbus has to stop the production of five-axis large-scale riveting equipment, remove the components, 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 was keen to integrate the stress wave riveting technology into two 5-axis automated riveting machines.

However, European mechanical experts have not realized this idea for more than half a year, the reason is very simple, because the riveting process is different, the quality and specifications of rivets are different, and Airbus cannot find a measurement standard and technical solution that can locate different rivets separately.

In this way, the two five-axis automatic riveting equipment looks very bright, but with the more and more extensive use of the stress wave riveting process, the two equipment in the hands of Airbus has gradually become a semi-automatic riveting machine, in addition to deceiving the media and the public, there is only self-deception.

Airbus originally thought that it would take five years for this technical problem to have some eyebrows, and at the turn of the century to have a preliminary result, so it was no longer eager and ready to fight a protracted war, but never expected that China's Tengfei Group not only solved this problem, but also successfully applied it to actual production, which was really not shocking to Jean Baker and others, who originally looked down on the Tengfei Group, but shocked.

So Jean Baker picked up the camera without saying a word, and was just about to press the shutter, when he heard Liu Chun next to him say slowly in English with a strong Shanghai accent: "A photo is five million US dollars, after all, we are not Boeing, it doesn't matter how you copy it, our Tengfei Group has a small business, and we can't afford your unscrupulous copying homework, besides, you Airbus is such a powerful company, can you still take a fancy to our things? It's a shame to spread it~~"

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