Chapter 649

It's not only Schumann's assistants and staff who feel like this, but they also feel that the color steel partition twice is like two times.

If everything behind them represents the industrial history of 30 years ago, it is no exaggeration to announce the future of industrial manufacturing to the world.

There are less than ten people in such a large production area, but even so, these people are not directly involved in the production and processing, but are more responsible for monitoring the operation of the equipment, adjusting the program, and handling the fault maintenance personnel.

Who is responsible for the production?

Naturally, they are strong and flexible mechanical arms, automatic processing machines, and circular suspended transport vehicles

"This is a complete set of automatic drilling and riveting processing zone for the main load-bearing structure and skin inside the helicopter. It is composed of six automatic drilling and riveting arms, four automatic riveting arms, two automatic skin riveting machines and eight suspension running vehicles. With the flexible tooling equipment developed by our group, it can realize the drilling and riveting of about 65% of the main load-bearing structure and skin of the helicopter Automatic drilling and riveting process. "

Just as everyone was amazed at the production scene that looked like a science fiction world, Wu Ping, who had been following Zhuang Jianye all the time, slowly opened his mouth under the instruction of Zhuang Jianye. When the translator translated the words into words that Schumann and others could understand, he was surprised.

We should know that helicopter is different from other aircraft, because of its special flight mode, its structure is more complex, and the materials used are high-end. Because of this, in general, the drilling and riveting automation of helicopter is very low.

Riveting, in particular, can only be done manually in many places.

It's not that we don't want to use automatic equipment, but because in the riveting process of some titanium alloy structural parts with different thickness, honeycomb structure, carbon fiber and other composite materials combined with other materials, the properties of different materials are different, and the stress is different, which leads to the single program automatic riveting equipment can't be applied.

In addition, the lack of professional flexible tooling equipment, not to mention the general aircraft manufacturers, even helicopter giants such as Bell and Sikorsky in the United States will have a penetration rate of 50% in drilling and riveting automation, and the rest will have to be manual.

However, the drilling and riveting process in Xiangzhou helicopter assembly workshop has achieved 65% automation rate.

To tell you the truth, if you didn't see it with your own eyes, one of the foreigners present is one. I can't believe the data is true.

In particular, Schumann, as a professional helicopter maintenance expert, helicopter manufacturers all over the world have not seen it, but they have seen it carefully. Especially for the helicopter manufacturers in the Soviet Union and the United States, Schumann has made great efforts to study it, but none of them has the same high level of automation rate as Xiangzhou helicopter assembly plant in terms of drilling and riveting technology .

How could China, which is generally backward in aircraft and shipbuilding production, possibly surpass the Soviet Union and the United States? It's not scientific at all.

Other people can say that it's hard to talk, but Schumann is an expert in this field, because others don't know, but he knows that drilling and riveting technology in helicopter production is not easy, relatively speaking, drilling is good, EDM, water cutting, laser, electron beam There's always a way to do it if you think about it.

But riveting is not good. To put it mildly, this process is to use brute force to flatten the rivets, so that they can fix the plates and parts.

Of course, this process is also very particular. After all, the force used in riveting different materials is different. Otherwise, the rivets will be hammered down, and the surrounding plates will be hammered and cracked, and then they will be dried in vain?

So what rivets are used for different materials, what forces are used, where are the force generating points, and how to control It's all knowledge. It's not a senior technical worker who has been in this type of work for more than ten years. He can't play in this field at all.

Since it's an experiential process, you can imagine how difficult it is to do automation.

It's just like a top chef. The same materials and dishes are delicious, because his experience is there. How much oil, salt, sauce and vinegar to put, how to put it, and when to put it, can only be meaningful, but can not be explained.

That's why the same dish can't taste like a chef when it's cooked by someone else. It's even more difficult to popularize mass production.

The drilling and riveting of helicopters are the same, and in some ways, it is several times more difficult than cooking.

If it were anywhere else, with Schumann's pure German urine, he would have opened his mouth and directly pointed out the non operability. The problem is that at this moment, he is in Xiangzhou factory of Tengfei group, and Zhuang Jianye, who he wants to curry favor with, is standing not far away, quietly watching their surprise and surprise. He seems to enjoy it very much.

Schumann is honest, loyal and loyal, and Zhuang Jianye has to throw all this into the garbage. So Schumann wisely did not open his mouth, but squinted and carefully observed the details.

That attitude is very obvious. I can say nothing, but I have to be thorough. Otherwise, in the future, Tengfei group will use this set of tricks to deceive Leipzig company, and I know the details, right?With this idea, Schumann took it a lot more seriously. A few robotic arms responsible for automatic drilling are no big deal. They also have them in Leipzig's repair shop. Even two of them are the same as those in front of us. They are all made by German companies.

Flexible tooling equipment is good. In this respect, Germany is weaker and the United States is more expensive. At that time, it will be said that we have to import some from Tengfei group.

In this way, while watching and commenting, Schumann soon came to the riveting processing zone, and the two mechanical arms introduced to him were still the same ones in their repair factory. It seems that Schumann's lack of interest. The core mechanical arms are all imported from Germany, and it seems that the so-called automatic riveting is nothing more than that.

In his mind, Schumann was ready to go around to see what happened to the two riveting machines behind him. At this moment, the two mechanical arms that he had labeled as such turned quickly and aligned on both sides of the plate that had just been put down and fixed from the trolley, and then "suddenly ~ suddenly ~ suddenly ~" rang.

Hearing this sound, Schumann, who was about to leave, suddenly stopped. Then the sound of "Tu ~ ~ Tu ~ ~ ~" became clearer. Schumann's eyebrows suddenly jumped and immediately turned his head to look at the two running mechanical arms. It was only then that he found that the top ends of the two mechanical arms doing riveting process seemed different from the riveting tools he knew.

The sound is very small, the speed is very fast, the molding rate is very high, especially the unique cable and capacitor structure. After only a few eyes, Schumann's eyes are as if he was born into the world, and he starts to open up uncontrollably. Then he points out his finger to the running mechanical arm, and his mouth shakes and cries: "this This This This is what fighters and bombers use Used in Stress wave riveting
