Take Off My Aviation Era

　　 "En~~~"

After watching carefully for a while, the middle-aged man opened his eyes and squinted again, folded his arms around his chest, and shook his round head: "No~~not the precision casting process, but! The most important mold in the precision casting process Manufacturing method, but also a new method of manufacturing precision casting molds."

The middle-aged man became more and more frightened as he looked at it. Although only a few paragraphs were written on the paper and it was not coherent, he could see what Zhuang Jianye was doing at a glance with his technical qualities. But because of this, he was very strange. , Because Zhuang Jianye wrote that it is not the manufacturing method of Yonghong factory's existing turbine director precision casting mold, but a brand new production plan.

　　 And the thinking and data seem reasonable.

　　 This made him a little surprised. It should be known that as the heated part of the aero engine second only to the turbine blade, the working environment of the turbine director is quite harsh. Because of this, its production has always been a problem in the manufacture of aero engines.

　　 Not to mention the method of making a new mold, it is not easy to fully understand the old mold production process.

The second workshop of the final assembly is well-known in China for its excellent precision casting technology. One of the second workshops of the final assembly is that the second workshop of the final assembly has unique experience in the precision casting molds of the turbine director. The second workshop has been constantly exploring for ten years, and it has achieved today's results.

　　It can be seen how difficult it is to master this type of precision casting mold.

　　The problem is that the second assembly workshop uses mature craftsmanship, but Zhuang Jianye has done a brand-new precision casting mold design, and it seems to be progressing well. The difficulty and hardship are simply not the same.

　　 So he looked at Zhuang Jianye, who was ignorant of him, and always leaned on the table to write things, and asked: "Little comrade, did you make the mold of this turbo directional device?"

"I really want to be with others, but unfortunately no one, I can only do it by myself!" Zhuang Jianye was very annoyed by this guy who was yelling next to him. He would recognize it when he recognized it. Why did he call it out? I almost scared myself. I interrupted my train of thought, so I was not polite.

The middle-aged man didn’t care about the thorn in Zhuang Jianye’s words. Instead, he pulled a chair from the side and sat down unceremoniously. He looked at what Zhuang Jianye had just written, and continued to ask like a curious baby: "You This is the water-soluble block molding method?"

Zhuang Jianye understands that the guy next to him didn’t come to find information, but deliberately made trouble. There was such a person who was chatting next to him, so he couldn’t feel relieved. He simply put down his pen and turned his head to look at the middle-aged man: "No Wrong, it is the water-soluble block molding method"

　　 "I remember that our factory uses a combination of single-blade wax molds and discs. Yours seems to be different from the factory." The middle-aged man looked at Zhuang Jianye in confusion.

　　 Zhuang Jianye's old face blushed slightly, and he said that this product is still a connoisseur, and the technical documents have been corrupted by him. He knows what methods are used in the factory, and now he is a little embarrassed to encounter connoisseurs.

But he couldn't admit that he had made the manuscript file miserable. If Director Yan and the others knew, he wouldn't be able to knead and round himself, so Zhuang Jianye quickly adjusted his state, his face was not red and heartbeat. Looking at the middle-aged man, until he saw the middle-aged man feel a little hairy, he touched his slightly fat round face and asked, "What's wrong? What's the problem?"

　　 "Don't you find it difficult to grasp the accuracy of the turbine director made by the method in the factory?"

　　 The middle-aged man didn't expect that Zhuang Jianye watched him for a long time, but then asked him such a question. He didn't know how to answer for a while, and Zhuang Jianye was not prepared to give the middle-aged a chance to speak.

He was so guilty that he couldn't give the initiative to others, so he immediately added a sentence: "The answer is obvious, it must be difficult to grasp, because of the two methods of the single-blade wax mold and the disc body combination method, Whether it is a combination of a profiling tool or a welding combination, a complex and large jig is required, which is not only difficult to operate, but also frequent replacement of the position of the component. How to grasp the accuracy of such a difficult operation?

"This..." The middle-aged man frowned and wanted to speak, but Zhuang Jianye stretched out his hand to stop it, and continued: "I know you want to talk about the steel living block method, the accuracy will be more guaranteed? That's right, American Many aviation manufacturing companies use this method. The problem is that the United States is rich in wealth and can afford the high cost of steel living blocks. Our factory has a thin foundation and few resources. This is 4 times more expensive than other molds. , And the time-consuming and long-term method is simply not practical for our factory."

With that, Zhuang Jianye sighed with a sacred look on his face, and said, "So I think about it, but the water-soluble living block molding method is good. The molding accuracy is guaranteed and the cost is not The more important thing is to remove the complex and large-scale fixture links, which greatly reduces the manufacturing difficulty, and is very suitable for our factory."

After saying such a long list of words, Zhuang Jianye was also a little dry. He picked up a tea mug on one side and drank his saliva. Upon seeing this, the middle-aged man finally caught the opportunity to speak: "It seems that you are very familiar with the precision casting of the turbo directional device. There is research."

"It’s okay. My university degree is flight engine power engineering. I have done research on turbo orientators. I tell you, UU reading www.uukanshu.com. This turbo orientator is very important. First-level turbo and second-level turbo If there is no such thing, the airflow cannot be introduced smoothly back, but because of this, the working environment of the director is very harsh, and the requirements on the components are very high. Fortunately, it is fixed on the turbine shaft, unlike the blades. It also needs to move at a high speed, without high-speed centrifugal force, so the difficulty is a little bit less..."

　　 After drinking the water, Zhuang Jianye was resurrected as full of blood. Let’s start, let’s go to the basics of the turbo directional device in popular science. It looks like he has been holding back for countless years and finally found a soulmate to talk.

　　 In fact, Zhuang Jianye's idea is very simple, he quickly grinds away the goods and pulls it out, so as not to ask questions here, it will be broken if you ask yourself.

　　 As a result, the middle-aged man next to him was more patient than him, and he heard it with gusto. He even poured himself a glass of water and listened to it as he listened to it. It seemed like listening to a storytelling, how cozy and cozy.

Zhuang Jianye also convinced this person, so boring things can be heard, but that's it, because he is ready to get off work, so he looked up at the clock on the wall and smiled apologetically: "Sorry. , I’m off work, did you find your information? If you don’t find it, come back after work in the afternoon."

This is the eviction order. The middle-aged man was a little disappointed on his face. He stood up and adjusted his old Chinese tunic suit. He nodded unceremoniously: "Okay, then I'll come back this afternoon." Then he walked to the door before leaving the house. Shi suddenly remembered something, turned his head and asked Zhuang Jianye: "Little comrade, I haven't asked what your name is."

　　 "Zhuang Jianye!" Zhuang Jianye replied, walked out of the archives, turned around and locked the door, the middle-aged man standing on one side looked up and down Zhuang Jianye in surprise, as if he knew Zhuang Jianye again: "You are Zhuang Jianye?"
