Chapter 46

After listening to the shot peening process, Lin Guanghua and others were at a loss. Obviously, they were very unfamiliar with it, but Shi Jun was at a loss. It seemed that they were not unfamiliar with it.

Qiao Chenyu laughed: "Xiaoshi, do you know shot peening?"

"I have read some foreign language materials in the school, which have been mentioned." Shi Jun did not hide it, but responded.

"Oh? Tell me about it Qiao Chenyu was also a little curious. Shi Jun nodded and continued: "the so-called shot peening forming, as the name suggests, is a process of cold working parts with small metal shot peening. In our aviation industry, the main application is to process the whole stiffened panel or thick skin, which is often called wing panel and complex skin parts.

As we all know, because of the large size, thin and thick plate, strong layer, complex internal structure, it brings many difficulties to the forming work. At present, we are using the Soviet skin roll bending machine, type K Α - 2, to process this kind of parts by roll bending

After a pause, Shi Jun sighed and continued: "it's just that the roll bending machine uses the roll bending method of three fulcrum bending principle to form single curvature wing, tail and integral skin panel parts. It's not that the roll bending machine uses the roll bending method of three fulcrum bending principle to form single curvature wing, tail and integral skin panel parts An ideal method.

It's only because this method has low forming accuracy and difficult quality control. In the overall processing, it not only needs skilled and accurate operation, but also needs sheet metal workers to make a lot of manual correction after forming. However, the shot peening process mentioned by director Qiao can well avoid the shortcomings of the roll bending machine. Not to mention, it also has a good strengthening and eliminating effect on the strength and stress of the overall panel, which is very important Inherent advantages of shot peening process. "

"Yes, Xiaoshi is right."

Qiao Chenyu looked at Shi Jun with admiration. He felt that he had really found treasure. He had strong ability, was willing to work hard, had a wide range of knowledge, and knew enterprise management. Such a compound talent was a model for young workers in the factory.

In contrast, Zhuang Jianye, who was favored by the chief engineer, was much worse. Although he quietly helped the two branches to carry out technological transformation, Qiao Chenyu still didn't think that he was better than others. You know, many of the new college students have published professional papers, and the worst one has written Research on technological improvement in authoritative magazines.

Now, among his staff, Lin Guanghua is the worst, but there is also a paper and a technical article in hand. What does Zhuang Jianye have? There's nothing. Oh, it's not right. Zhuang Jianye has got Minister Ning's daughter. She's very capable.

But this kind of ability is really nothing to Qiao Chenyu, who attaches importance to scientific research achievements. Therefore, during the meeting in Beijing, the chief engineer asked him to set up a trial model R & D team. Qiao Chenyu took the public achievements as a rigid index, and Zhuang Jianye was naturally excluded.

Of course, it's all out of the question. Now, as long as we get the trial model and work hard, Qiao Chenyu doesn't believe that his young men can be any worse. What about the father-in-law of the organized Minister? Those who have real skills are the long-term way to go.

As soon as the thought in my head flashed by, my smile became more cordial: "shot peening technology is still a new thing in our country. It has just started, but it has been popularized in developed countries such as Europe and the United States. Especially in powerful aviation enterprises such as Boeing and McDonnell Douglas, a single wing panel has to be 20 or 30 meters long. What kind of roll bending function can be processed, What's more, even if there are, the inherent defects of the bending machine will also make such parts have defects, affecting flight safety.

So they have long applied shot peening technology to the forming of wings, tails and skins of large aircraft. As far as I know, this technology has been applied to B-52 bombers, Boeing 707, Boeing 747, DC-10 and other aircraft in the United States. In addition, shot peening technology has also been applied to the new generation of combat aircraft in Europe and the United States. It can be said that this technology has become an important part of the aviation industry The core technology has become the first choice for wing and tail manufacturing. "

Lin Guanghua and others are very stupid. They didn't expect that this technology is the core technology of wing and tail manufacturing in Europe and the United States. Let alone them, even Shi Jun, who is knowledgeable, was surprised. He knew that shot peening technology is very important, but he didn't expect that it would be so important.

So the next moment, a hot heart will pop up. Since Qiao Chenyu said so, he also took them to the so-called "copper head" general assembly workshop No. 1, that is to say, they will participate in the key task which is regarded as the core by European and American aviation powers.

Not only him, but Lin Guanghua and others are aware of this, and their faces are red. No matter how selfish they are, their enthusiasm for serving the country by aviation has never been eroded. If they can catch up with the world's advanced technology through their hands, it will be their lifetime glory.

Qiao Chenyu didn't say anything more. He just looked at the young people's passionate appearance, as if he saw his ambition when he first entered the factory. He nodded happily, spread out his technical information on the long table, and said, "let's start now."

There are no grand slogans or solemn rituals. At the beginning of a simple sentence, people will understand that they are shouldering the burden of catching up from now on.

One by one, they immediately put in a hundred and two percent of their enthusiasm and plunged into it.Soon three days later, under the leadership of Qiao Chenyu, Shi Jun and others reorganized the data and made a more detailed analysis of the data. Everything seemed very smooth, as if a brand-new spray molding machine was about to come out.

But the more so, the more frowning Qiao Chenyu, the leader, was, because behind the smooth progress, he couldn't make up his mind about several key data and structures. He couldn't help that these things appeared too abrupt, without explanation or argument, as if they were springing out of a stone.

Qiao Chenyu didn't care when he first found out. He asked Shi Jun and others to get around and wait for chief engineer he to come back. After all, chief engineer he was the leader in those years, and no one was more familiar with him.

However, with more and more abnormal data and structures, Qiao Chenyu's heart is not calm. He was promoted by chief engineer he. He is very clear about chief engineer he's character, that is, he is rigorous, so rigorous that no deviation is allowed, and even a decimal point should be deducted reasonably. How can he get so many abnormal data and structures without detailed demonstration ？

As a result, the seemingly smooth shot peening process has entered a bottleneck. There are too many abnormal data to go around. In order not to delay the progress, Qiao Chenyu has no choice but to suspend the theoretical research and let Shi Jun and others work hard on the materials.

Then we wait for chief engineer he to come back and see if something went wrong that year.

He Ming rushed back to Yonghong factory last night. After a night's rest, he came to the first general assembly workshop early in the morning and stepped into the process room. Without too much communication with Qiao Chenyu, he picked up the information on the table and scanned it. Then he shook his head and said something that made Qiao Chenyu shocked: "these data and structures are not made by me."
