It is no wonder that Zhuang Jianye is so surprised, it is really flexible tooling technology has a pivotal position in the field of modern aviation manufacturing.

As we all know, aircraft manufacturing is a huge and precise system engineering, and because of this, for a long time, aircraft manufacturing can not implement assembly line operations like automobiles, and can only take the aircraft model as the core to implement design, manufacturing and final assembly.

Because of this, the tooling equipment used to fix, rotate, move, and mold aircraft parts is generally designed separately and independently matched according to the specific aircraft model.

Although the accuracy and consistency of various parameters in the remanufacturing of the aircraft are ensured in this mode, and the aircraft design indicators are implemented, this kind of tooling matching like a radish and a pit is not suitable for versatility and limitations.

The most typical example of this is the tooling equipment of Yunten, not that other factories do not want to use these equipment, the problem is that the tooling equipment of Yunten can only be applied to the aircraft of this type of Yunten, unless the aircraft made by other factories is exactly the same as the parameters of Yunten, and it can also be used.

Therefore, this kind of elimination of a large number of expensive tooling equipment with the disassembly of the model is not a waste of production enterprises, but a helpless move to limit the double restriction of production mechanism and process level.

Is there any tooling equipment that can be applied to different types of aircraft, and can be used flexibly for different parts and different angles?

Of course, as early as the sixties, the American aviation giants developed a flexible tooling technology based on the vacuum adsorption of multi-matrix columns.

And applied to several different types of aircraft, not only reduce the production cost, with the high precision of CNC machine tools, but also greatly improve the production efficiency, so that the United States aircraft production capacity to a new level.

The reason for this is that this flexible tooling technology has excellent versatility and flexible control angles, allowing American aviation companies to save nearly half of the tooling design time.

In a sense, it is not much easier than aircraft design, and because of this, traditional aircraft manufacturing is not only slow, but also very inefficient, and it is completely a technology-intensive and manpower-intensive industry.

The emergence of flexible tooling technology has completely subverted the traditional tooling model of one machine and one type, using the scalability of the column matrix, graceful as the humanoid reflection board in the amusement city, which can be fixed, moved and even flipped on the pre-processed parts according to different models and different parameters, and is completely not limited by models and parameters.

It stands to reason that such a good thing, the domestic aviation manufacturing industry will not be indifferent, should have thought of it a long time ago, not to mention that the basic principle of this matrix-type flexible tooling technology is very simple, and the human-shaped reflection board in the playground of later generations is the same principle.

But after so many years, the whole world except for the United States, even the Soviet Union, which is also among the superpowers, does not have similar technology, although Europe has applied flexible tooling technology to produce its own passenger aircraft, but still uses equipment produced by the United States.

It is inconceivable to think about such a simple principle, which is only done by the United States, but it has to be relieved when it is carefully investigated, because this technology, like aero engines, does not lie in the principle, but in the core of accurate measurement and control technology.

You must know that any part of the airplane is the optimal solution after complex calculations, and a child can outline a humanoid silhouette by lying on the humanoid reflection board full of columns in the playground, and if the parts of the airplane are so casual, then aircraft manufacturing cannot become a high-end industry that only a few countries can play.

Because of this, the key to flexible tooling technology is that each matrix column raises the geometry and expands a little as it fixes the components, whether it needs to remain stationary or need to be adjusted in multiple directions.

This seems to be a simple change, but it is obviously unrealistic to use manpower to detect and calculate, and the small parts are fine, just like the Boeing 747 passenger plane, the C-5 strategic transport plane, and the B-52 strategic bomber.

Of course, even if you are not afraid of hard work, use manpower to fill in, and really measure it out, but people are not machines after all, there are always naps, when you are confused, in case you accidentally go away during the measurement, the data is a few decimal places, and the consequence may be that the machine is destroyed and people die.

Because of this, there must be a set of position control, accurate measurement, mobile positioning in the flexible tooling equipment in one of the integrated control system.

In this regard, the United States is unique in the world, and it is precisely because of this that their flexible tooling technology can lead the world.

There was a similar project in China in the seventies, but because the whole control system was too complex, especially in the application of computers, the component database of domestic aircraft models was completely blank, so after a few years of stuck, I had no choice but to give up.

Not to mention the domestic market, even the Soviet Union, which can compete with the United States in the field of aviation, is not as good as the United States in this regard, otherwise the more the late Cold War, the more the Soviet Union is left behind by the United States in the field of aviation, not only in terms of simple aircraft design, but also in the production capacity that the Soviet Union is proud of can not keep up with the pace of the Americans, and the root is here.

The Americans can build six models and more than 40 kinds of parts in a set of tooling, while the Soviet Union can only build one model and two or three parts, and the efficiency and cost are simply incomparable, so it is strange that they do not lag behind.

Fortunately, the Soviet Union couldn't play with technology, so it fought with brute force, as long as it could fly the plane into the sky, the cost and efficiency of the manufacturing link were not a problem.

The Soviet Union could play like this, but the domestic aviation industry could not be fooled around with the Soviet Union, firstly, no one was so rich, and secondly, the reform also made the domestic aviation industry gradually understand the importance of efficiency.

In particular, Tengfei Factory is almost a typical representative of making money, so Zhuang Jianye has long wanted to start with tooling, so as to further reduce costs.

No way, now Tengfei factory produces a total of five UAV models, and actually uses four different sets of tooling equipment, which is equivalent to spending three more money, which is just that, if a drone is stopped one day, it will lose its value to build tooling equipment with heavy money, which is a big waste.

Based on this, Zhuang Jianye wants to get the flexible tooling technology into the Tengfei factory, improve efficiency and reduce costs, the problem is that he has this heart, but no one gives this opportunity.

The Americans are very strict in this regard, after all, the pillar of the United States' hegemony in the world is the aviation manufacturing industry, and what supports their aviation manufacturing industry is their unique aviation manufacturing technology.

Because of this, these things are really not what you want to buy, people can sell you, Zhuang Jianye hopes to get a set of equipment back through different channels, but the result is all a nose of dust.

But just when he had nothing to do and was about to wait for another two years to do it himself, Mr. Lindemann actually smashed this big gift, which really surprised Zhuang Jianye.
