Chapter 312

No wonder Zhuang Jianye is so surprised. Flexible tooling technology plays an important role in modern aviation manufacturing.

As we all know, aircraft manufacturing is a huge and sophisticated system engineering. Because of this, for a long time, aircraft manufacturing can not implement assembly line operation like automobile. It can only implement design, manufacturing and final assembly with aircraft model as the core.

Because of this, for aircraft parts fixed, rotating, moving, mold and other tooling equipment, are generally designed according to the specific aircraft model, independent matching.

In this mode, although the accuracy and consistency of various parameters during aircraft remanufacturing are ensured, and the aircraft design indicators are well implemented, this kind of tooling matching like a radish and a pit, therefore, has poor versatility and many limitations. Often after the aircraft model order is delivered or forced to dismount, these tooling equipment will exit the historical stage with the model. As like as two peas, the most typical example of

is the equipment for transporting 10 of the equipment, not the other factories do not want to use these equipment. The problem is that the 10% of the equipment can only be applied to the 10 model aircraft, unless other factories are similar to those of the other 10 aircraft.

Therefore, the elimination of a large number of expensive tooling equipment with the model is not a waste of the production enterprises, but a helpless move due to the double restrictions of production mechanism and technological level.

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

Of course, as early as the 1960s, American aviation giants developed a flexible tooling technology based on multi matrix column vacuum adsorption.

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

The reason is that this flexible tooling technology has excellent versatility and flexible control angle, which makes the American aviation enterprises save nearly half of the tooling design time.

The traditional aircraft manufacturing tooling design is by no means an easy job. In a sense, it is not much easier than aircraft design. Because of this, the traditional aircraft manufacturing is not only slow, but also inefficient. It is a technology intensive and human intensive industry.

However, the emergence of flexible tooling technology completely subverts the traditional one machine one type tooling mode. By using the scalability of column matrix, it can fix, move or even turn the pre processed parts according to different models and parameters, such as the humanoid reflection board in amusement City, which is completely free from the restrictions of models and parameters.

It is reasonable to say that the domestic aviation manufacturing industry will not be indifferent to such a good thing. It should have thought of it long ago. What's more, the basic principle of this matrix flexible tooling technology is very simple, and the humanoid reflection board in later amusement parks uses the same principle.

But after so many years, except for the United States, even the Soviet Union, which is also one of the superpowers, has no similar technology in the world. Although Europe has applied the flexible tooling technology to produce its own airliner, it still uses the equipment produced by the United States.

It's incredible to think that only the United States can do such a simple principle, but we have to be relieved to investigate it carefully, because this technology, like aeroengine, does not lie in the principle, but in the core precision measurement and control technology.

You need to know that any part of an aircraft is the optimal solution obtained through complex calculation. When children lie down on the humanoid reflection board full of columns in the playground, they can outline a humanoid shape. If the parts of an aircraft are so casual, then aircraft manufacturing can not become a high-end industry that only a few countries can understand.

Because of this, the key of flexible tooling technology is to raise the geometry of each matrix column when fixing the parts, stretch a little, keep still or need multi-directional adjustment.

This seems like a simple change. It's obviously unrealistic to test and calculate by manpower. The small parts are OK, but how many people can measure one column by one for such big guys as Boeing 747, C-5 strategic transport aircraft and B-52 strategic bomber?

Of course, even if we don't have to work hard and use manpower to fill in the data, we can really measure it out. But after all, people are not machines. There are always times when they doze and are confused. If they accidentally go away when measuring, and the data is a few decimal points short, the result may be that the machine will be destroyed and people will die.

Because of this, flexible tooling equipment must have a set of integrated control system integrating position control, accurate measurement, mobile positioning.

In this respect, the United States is the only one in the world. Because of this, their flexible tooling technology can lead the world.

There was a similar project in China in the 1970s, but because the whole control system was too complex, especially in the application of computer, the database of domestic aircraft parts was completely blank, so after several years of card, I had no choice but to give up.

Not to mention in China, even the Soviet Union, which can compete with the United States in the aviation field, is not as good as the United States in this respect. Otherwise, the more late the cold war, the more far the Soviet Union is left behind by the United States in the aviation field. Not only in aircraft design, but also in the production capacity that the Soviet Union is proud of, it can't keep up with the pace of the United States.The United States can make six models and more than 40 parts for a set of tooling. The Soviet Union can only make one model and two or three parts. The efficiency and cost of these models can hardly be compared with each other.

Fortunately, if the Soviet Union could not turn its technology around, it would fight for brute force. As long as it could fly the plane into the sky, the cost and efficiency of manufacturing were not a problem.

The Soviet Union can play like this, but the domestic aviation industry can not compete with the Soviet Union. On the one hand, no one is so rich. On the other hand, the reform has made the domestic aviation industry gradually understand the importance of efficiency.

Tengfei factory, in particular, is almost a typical example of making money. Therefore, Zhuang Jianye has long wanted to start with tooling to further reduce costs.

There's no way. Today, Tengfei factory produces five UAV models, and actually uses four different sets of tooling equipment. This is equivalent to spending three more. That's all. If one UAV stops production one day, the heavy investment in tooling equipment will lose its value, which is also a great waste.

Based on this, Zhuang Jianye wants to bring flexible tooling technology to take off factory, improve efficiency and reduce cost. The problem is that he has this heart, but no one gives him this opportunity.

Americans are very strict in this respect. After all, the pillar of the United States dominating the world is the aviation manufacturing industry, and what supports their aviation manufacturing industry is their unique global aviation manufacturing technology.

Because of this, these things are not really what you want to buy, and people can sell them to you. Zhuang Jianye hopes to get a set of equipment back through different channels, but all of them come to nothing.

But when he had nothing to do and was ready to wait another two years to do it by himself, Mr. Linderman smashed the gift, which really surprised Zhuang Jianye.
