Chapter 312 Big Gift

    No wonder Zhuang Jianye is so surprised. In fact, flexible tooling technology plays a decisive role in the field of modern aviation manufacturing.

    As we all know, aircraft manufacturing is a large and precise system engineering. Because of this, for a long time, aircraft manufacturing has not been able to implement assembly line operations like automobiles. It can only implement design, manufacturing and final assembly with the aircraft model as the core.

    Because of this, tooling equipment used for fixing, rotating, moving, and molding aircraft parts is generally designed and independently matched according to the specific aircraft model.

    Although this mode ensures the accuracy and consistency of various parameters during aircraft remanufacturing and implements the aircraft design indicators, this kind of tooling is like a carrot and a pit, so it has poor versatility and many limitations. It is often in the aircraft model order.  After delivery is completed or forced to be discontinued, these tooling equipment will withdraw from the stage of history along with the model.

    The most typical example in this regard is Yunshi's tooling equipment. It's not that other factories don't want to use these equipment. The problem is that Yunshi's tooling equipment can only be applied to one type of aircraft, unless the aircraft manufactured by other factories are different from Yunshi.  The parameters are exactly the same and can still be used. If there is a slight change, these fixed tooling equipment will be useless at all.

    Therefore, the elimination of a large number of expensive tooling equipment as models are discontinued is not a waste of money by the production companies, but a helpless move due to the dual limitations of the production mechanism and process level.

    Is there any tooling equipment that can be applied to different types of aircraft and can be flexibly used on 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, it not only reduces production costs, but also greatly improves production efficiency in conjunction with the high precision of CNC machine tools, thus bringing the U.S. aircraft production capacity to a new level.

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

    The tooling design of traditional aircraft manufacturing is by no means an easy job. In a sense, it is not much easier than aircraft design. Because of this, traditional aircraft manufacturing is not only slow, but also very inefficient. It is completely technology-intensive and  Industries that are labor-intensive and superimposed on each other.

    The emergence of flexible tooling technology has completely overturned the traditional one-machine-one-type tooling model. Using the scalability of the column matrix, like the human-shaped reflection board in an amusement park, pre-processed parts can be processed according to different models and different parameters.  It can be fixed, moved or even flipped without being restricted by the model and parameters.

    It stands to reason that the domestic aviation manufacturing industry would not be indifferent to such a good thing. They should have thought of it long ago. What's more, the basic principle of this matrix-type flexible tooling technology is very simple. The same human-shaped reflection panels in later generations of amusement parks were used.  principle.

    But after so many years, except for the United States, even the Soviet Union, which is also a superpower, does not have similar technology. Although Europe uses flexible tooling technology to produce its own passenger aircraft, it still uses American production.  equipment.

    It¡¯s unbelievable that only an American company can do such a simple principle, but when you look into it carefully, you have to be relieved, because this technology is the same as an aerospace engine. It does not lie in the principle, but in the core precise measurement and control technology.  superior.

    You must know that any component on the airplane is the optimal solution obtained through complex calculations. A child can outline a human figure by lying on the human-shaped reflection board full of pillars in the playground. If the components of the airplane are  If it is so casual, it is impossible for aircraft manufacturing to become a high-end industry that only a few countries can understand.

    Because of this, the key to flexible tooling technology is the lifting geometry of each matrix column when fixing the component, how much it expands and contracts, and whether it needs to remain stationary or needs to be adjusted in multiple directions.

    This seems to be a simple change, but it is obviously unrealistic to simply use human power to detect and calculate. Small parts are fine, but big ones like the Boeing 747 passenger plane; the C-5 strategic transport aircraft; and the B-52 strategic bomber, how many people can do it?  Measure one pillar by one?

    Of course, even if you are not afraid of laborious work and fill it in manually, the measurement will actually come out. But after all, people are not machines. They always fall asleep and get confused. If you accidentally go wrong during the measurement, the data will be off by a few points.  Decimal point, the consequences may be the destruction of the machine and the death of people.

    Because of this, flexible tooling equipment must have a comprehensive control system that integrates position control, precise measurement, and mobile positioning.

    The United States is unique in the world in this regard, and because of this, their flexibilityOnly with clothing technology can we lead the way in the world.

    There was a similar project in China in the 1970s, but because the entire control system was too complex, especially in terms of computer applications, the parts database for domestic aircraft models was completely blank, so after being stuck for a few years, it had no choice but to give up.

    Not to mention domestically, even the Soviet Union, which could compete with the United States in the aviation field, was not as good as the United States in this regard. Otherwise, the later the Cold War, the Soviet Union became further and further behind the United States in the aviation field, not just in terms of pure aircraft design.  , even the production capacity that the Soviet Union was proud of could not keep up with the pace of the Americans. The root cause is here.

    The Americans can make six models and more than 40 parts for a set of work clothes, while the Soviet Union can only make one model and two or three parts. The efficiency and cost are simply different. It would be strange if they don't lag behind.

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

    The Soviet Union can play like this, but the domestic aviation industry cannot mess around with the Soviet Union. Firstly, no one is so wealthy. Secondly, reforms have also made the domestic aviation industry gradually understand the importance of efficiency.

    Especially Tengfei Factory, which is almost a typical representative of people who want to make money, so Zhuang Jianye has long wanted to start with workwear to further reduce costs.

    There is no way. Now Tengfei Factory produces a total of five drone models and actually uses four different sets of tooling equipment. This is equivalent to spending three more dollars. That's it. If one day a certain drone is discontinued  , the heavy investment in building tooling equipment will lose its value, which is another huge waste.

    Based on this, Zhuang Jianye really wanted to bring flexible tooling technology to Tengfei Factory to improve efficiency and reduce costs. The problem was that he had this intention, but no one gave him the chance.

    Americans take this aspect very seriously. After all, the backbone of the United States' world dominance is its aviation manufacturing industry, and what supports their aviation manufacturing industry is their world-leading aviation manufacturing technology.

    Because of this, if you really want to buy these things, they can sell them to you. Zhuang Jianye tried to get a set of equipment through different channels, but all ended in disappointment.

    But just when he was at his wits' end and prepared to wait another two years to do it himself, Mr. Lindemann actually threw this gift at him, which really surprised Zhuang Jianye beyond measure.
