Chapter 649 Stress wave riveting

Previous page        Return to Catalog        Next page

    Not only the assistants and staff of Schumann and others felt this way, but they themselves also felt that the color steel partition was like two eras.

    ¡°If everything behind them represents the industrial history of thirty years ago, then the scene in front of them can declare to the world the future of industrial manufacturing without exaggeration.

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

    Who is responsible for production?

    ???Naturally, there are thick and flexible robotic arms, automatically operating processing machines, and suspended transport vehicles that circulate back and forth

    "This is a complete set of automatic drilling and riveting processing areas for the helicopter's internal main load-bearing structure and skin. It consists of six automatic drilling robotic arms, four automatic riveting robotic arms, two automatic skin riveting machines and eight suspension operating vehicles.  Combined with the flexible tooling equipment developed by our group, it can realize the automatic drilling and riveting process of about 65% of the helicopter's main load-bearing structure and skin."

    While everyone was marveling at the production scene that looked like a science fiction world in front of them, Wu Ping, who had been following Zhuang Jianye, slowly spoke under Zhuang Jianye's instruction. After the translator translated the words into words that Schumann and others could understand, they couldn't help but eat.  Startled.

    You must know that helicopters are different from other aircraft. Due to their special flight mode, their structures are relatively complex and the materials used are even more high-end. Because of this, under normal circumstances, the degree of automation of drilling and riveting of helicopters is generally very low.

    Especially riveting, in many places it can only be done manually by workers.

    It¡¯s not that I don¡¯t want to use automated equipment to complete it, but because some titanium alloy structural parts of helicopters with different thicknesses, as well as honeycomb structures, carbon fiber and other composite materials are combined with other materials during the riveting process. Different materials have different properties and stress.  For various reasons, automated riveting equipment with a single program cannot be used.

    Coupled with the lack of professional flexible tooling equipment, not to mention ordinary aircraft manufacturers, even helicopter giants such as Bell and Sikorsky in the United States will have a penetration rate of automation in drilling and riveting processes that will reach 50%.  The remaining half still has to be done manually.

    ¡°However, the drilling and riveting process in Xiangzhou¡¯s helicopter assembly workshop has achieved an automation rate of 65%.

    To be honest, if you hadn¡¯t seen it with your own eyes, every foreigner present would never believe that this data is true.

    Especially Schumann, as a professional helicopter maintenance expert, not only has seen all the helicopter manufacturers in the world, but 80% of them have carefully looked at them, especially the helicopter manufacturers in the Soviet Union and the United States. Schumann has made great efforts.  No one I have studied can achieve such a high level of automation rate as the Xiangzhou Helicopter Assembly Plant in drilling and riveting processes.

    Suddenly doubts arose. How could China, which was generally lagging behind in aircraft and shipbuilding production, overtake the Soviet Union and the United States?  It's not scientific at all.

    Others can be said to be stubborn, but Schumann is an expert in this field. Because others don't know, he knows that drilling and riveting in helicopter production is not easy. Relatively speaking, drilling is pretty good.  EDM, water cutting, laser, electron beam As long as you put your mind to it, there is always a way to do it.

    But riveting is not possible. To put it bluntly, this process is to use brute force to flatten the rivets to fix the plates and components.

    Of course, this process is very particular. After all, the force used when riveting different materials is different. Otherwise, if the rivets are hammered down and the surrounding plates are cracked, wouldn¡¯t it be in vain?

    So what kind of rivets to use for different materials, what force to use, where is the force point, how to control it are all knowledge. If you are not a senior skilled worker who has been working in this type of work for more than ten years, you will not be able to master this industry at all.

    Since it is a process that requires experience, you can imagine how difficult it is to automate.

    This is like a top chef. With the same ingredients, the chef's dishes will be delicious no matter how he cooks them, because his experience is there. You can only guess how much oil, salt, sauce and vinegar to put, how to put it, and when to put it.  explain in words.

    This is why the same dish cannot taste like a chef if cooked by another person. It is even more difficult to popularize mass production.

    The same is true for drilling and riveting of helicopters, and in some aspects it is several times more difficult than cooking for a chef.

    If this were anywhere else, Schumann would have opened his mouth and directly pointed out the inoperability of the purebred Germanic people. The problem is that at this moment, he is in the Xiangzhou Factory under the Ascendas Group, and he wants to curry favor.  Zhuang Jianye stood not far away and quietly watched their various surprises and surprises, as if??I still enjoy it very much.

    Schumann was upright and loyal, but Zhuang Jianye had to throw all of this into the trash, so Schumann wisely did not speak, but squinted his eyes to carefully observe the details.

    That attitude is very obvious. I can say nothing, but I must be transparent. Otherwise, Ascendas Group will use this trick to trick their Leipzig company in the future. I also know the details, right?

    With this thought in mind, Schumann took a more serious look. A few robotic arms responsible for automatic drilling are not a big deal. They also have them in the repair shop of their Leipzig company. There are even two of the same model as the ones in front of them.  It is produced by a German company.

    Flexible tooling equipment is indeed good, but Germany is weaker in this regard, and American equipment is more expensive. It is impossible to import some from Ascendas Group.

    Just watching and evaluating, Schumann soon came to the riveting processing area. The two mechanical arms that came into view were still the same ones in their repair shop. Seeing this, Schumann was a little uninterested. The core machinery  The arms are all imported from Germany. It seems that the so-called automatic riveting is nothing more than that.

    Thinking in his mind, Schumann was about to go around and see what was going on with the two riveting machines at the back. At this moment, the two robotic arms that he had labeled as "not so" quickly rotated and were just lowered from the crane truck.  The two sides of the fixed plate were aligned, and then a "burst~burst~burst~" sound was heard.

    Hearing this voice, Schumann, who was about to leave, suddenly stopped, and then the sound of "burst~~burst~~burst~~" became clearer. Schuman's brow suddenly jumped, and he immediately turned his head to look at the two  The robotic arm was running, and then I realized that the tops of the two robotic arms that were doing the riveting process seemed to be different from the riveting tools I knew.

    The sound is very small, the speed is very fast, and the molding rate is very high, especially the unique cable and capacitor structure. After just a few glances, Schumann's eyes began to widen uncontrollably, as if he had seen someone born on earth.  He stretched out his hand and pointed at the running robotic arm, and shouted with trembling mouth: "Thisthisthisthis isstress wave riveting that is only used by fighters and bombers!"
