Chapter 702 How embarrassing would it be if word got out?

Previous page        Return to Catalog        Next page

    No wonder Jean Baker and others were so surprised.

    A large piece of equipment more than three meters high stood in front of everyone. Two bright white steel support columns stood proudly like two European medieval armored knights. While supporting the entire equipment, they also  Fix the large semi-curved skin part in the middle that is nearly 2 meters long and 1.5 meters wide.

    That's all. Both Rickerson and Jean Baker have worked in the European aviation industry for half their lives. They have never seen any large equipment, so they will not be shocked by the three-meter-tall thing in front of them.  My jaw almost dropped.

    The key is that the equipment in front of you is not only huge, but more importantly, flexible.

    Yes, it is flexible, especially the processing probe at the core of the equipment. Just like a specially trained human arm, it shakes up, down, left and right at the large skin component in front of it, and then starts to perform automated riveting operations.

    Do you think this is the end?

    ?Then this machine seems too simple. Not only is the riveted probe flexible, but the support frames on both sides can also rotate along with the processing of the riveted probe.

    ?With excellent CNC programs, the entire equipment can complete very complex riveting processes in an extremely short time.

    If this were in the United States, Rickerson, Jean Beck, and others would not be surprised to see similar equipment. After all, Americans are really the best in the aviation industry. No matter how advanced the equipment is, it is reasonable.  .

    But the problem is that the place they are in at this moment is called China. In their eyes, a place with nothing to show off except for the large number of people. It can be called a technological depression. How can it have such advanced equipment?

    You must know that even Airbus only has two large-scale fully automatic riveting machines of this type. They are all located in the final assembly factory in Toulouse, France. They are mainly used for riveting of large-curved integral skin components on the sides of the A320 fuselage.

    It is precisely because of these two pieces of equipment that Airbus often brags about how advanced their processes are and how high their degree of automation is, in order to show potential customers that Airbus's A320 has been instilled with good genes since birth. You guys  Just buy it with confidence and be done with it.

    The reason why I dare to say this is very simple. There are really few aviation manufacturing companies in the world that can use large-scale fully automatic riveting equipment, and no one uses five-axis large-scale fully automatic riveting equipment except Airbus.

    As for whether this five-axis large-scale fully automatic riveting equipment is easy to use, there is no need to say. You must know that the traditional riveting of large skin parts does not matter other things, just marking this line is enough to keep people busy for a while.

    Someone asked, what is scribing? Its function is similar to a carpenter's ink line. Its main function is to determine the position of rivets. Because of this, the requirements for skin scribing are very high, and it must be purely manual. This is not a job in this industry.  The old master who has been working for many years simply cannot control it.

    Even though semi-automatic riveting equipment later appeared, the manual marking of the skin was still not replaced. Instead, it became an important process in the complete process of semi-automatic riveting equipment and became more indispensable.

    Because semi-automatic riveting equipment cannot position rivets by itself, they can only rely on manual marking of the marked ministries so that they can perform riveting processing in batches.

    It was not until Germany relied on its strong mechanical equipment research and development capabilities to build five-axis large-scale riveting equipment for Airbus that the manual marking step was completely replaced by machinery due to flexible multi-axis processing capabilities and perfect control programs.  .

    This has happened in the past two years. Japan, as the overseas OEM base for Boeing in the United States, is stepping up the development of similar equipment and is expected to be put into use in the mid-1990s.

    Aircraft processing plants in the United States do have similar equipment, but it is not produced in the United States, but imported from the German mechanical equipment company that builds five-axis large-scale fully automatic riveting equipment for Airbus.

    To this end, Airbus obtained a complete set of stress wave riveting technology from the United States, as well as the airworthiness certification of the American Aviation Administration for the improved A320 passenger aircraft.

    ¡°However, this type of important equipment that has made Airbus world-famous and gained a lot of benefits from the Americans is right in front of them at this moment.

    And it seems it is more flexible, more adaptable, and has more processing categories than theirs.

    Because just when they were surprised, the previous 2-meter-long skin part had been processed and replaced with not the same type of blank, but a 1.2-meter-long oblique triangular skin blank, which was obviously the wing.  Or something on the rear wing.

    But this is not the point. The key is that the entire equipment does not change the fixture, nor does it re-write the complex processing procedures. After it is installed using the hoisting equipment, the riveting probe shakes on it for a moment and thenI started working like a rapid fire, and the whole process was smooth and smooth, with no intention of delaying at all.

    That's all. What surprised Rickerson even more was that when riveting an important part, the original riveting probe suddenly deflected and was replaced by a new probe with a thicker arm. Then the sound became dull, but the inserted probe  The rivets were more than twice as thick as before.

    "This isstress wave riveting? Can it also achieve fully automatic transformation?"

    When Jean Baker saw this scene, he no longer exclaimed, but almost screamed. After obtaining stress wave riveting equipment from the Americans, Airbus immediately contacted many equipment suppliers and began to study how to apply this technology to  On fully automatic riveting equipment.

    After all, Airbus¡¯s two five-axis large-scale riveting equipment can only perform mechanical riveting and pneumatic riveting, and stress wave riveting cannot be performed 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 before continuing the automated riveting process.

    Because of this, Airbus is very interested in integrating stress wave riveting technology into two five-axis automated riveting equipment.

    However, European mechanical experts have been tinkering for more than half a year but have not been able to realize this idea. The reason is very simple. Because the riveting process is different, the quality and specifications of the rivets are different, and Airbus cannot find a measurement standard and technical solution that can position different rivets separately.

    In this way, the two five-axis automated riveting equipment looks very glamorous. However, as the stress wave riveting process becomes more and more widely used, the two equipments in Airbus' hands have gradually become semi-automatic riveting machines. In addition to cheating  The media and the public are left deceiving themselves and others.

    Airbus originally thought that it would take five years for this technical problem to be solved, and that preliminary results would be achieved at the turn of the century, so it stopped being impatient and prepared for a protracted war. However, it never expected that China's Ascendas Group not only solved the problem but  This problem has also been successfully applied to actual production. This is really not a shock to Jean Baker and others who originally looked down on Ascendas Group, but a shock.

    So Jean Baker picked up the camera without saying a word, and just as he was about to press the shutter, he heard Liu Chun next to him speak slowly in English with a strong Shanghainese accent: "A photo costs five million U.S. dollars. After all, we are not Boeing.  It doesn¡¯t matter how you copy. Our Ascendas Group is a small business and cannot withstand your unscrupulous copying operations. Besides, how can a company as powerful as Airbus like our stuff? How embarrassing would it be to spread the word?  ~~"

    With one word, Jean Baker, who was about to press the shutter, froze there, and his old face turned red with embarrassment!
