Listening to the shot peening process, Lin Guanghua and the others were at a loss, obviously very unfamiliar with it, and Shi Jun looked abrupt, as if he was not unfamiliar.

Qiao Chenyu smiled: "Xiao Shi, do you know shot peening?"

"I've seen some foreign language materials in school, and they have mentioned it. Shi Jun didn't hide it either, and responded.

"Oh, tell me about it. Qiao Chenyu was also a little curious, Shi Jun nodded, and continued to speak: "The so-called shot peening, as the name suggests, is a process of cold processing components with small metal shot peening, and the main application in our aviation industry is to process the reinforced integral wall plate or thick skin, which is what we often call wing wall plate and complex skin parts.

Everyone knows that this kind of parts brings many difficulties to the molding work due to the large size of the outer dimension, the thin and thick layer of the plate, and the complex internal structure. At present, we use the Soviet КГЛ-2 skin roll bending machine to process such parts by rolling and bending. ”

After a pause, he glanced at the КГЛ-2 skin bending machine that was still running in the hands of the workers not far from the workshop, running slowly and clumsily, making the sound of Caracalla, Shi Jun sighed and continued: "It's just that the roll bending machine uses the rolling bending method of the three-fulcrum bending principle to form the wings, tail and skin integral wall plate parts of single curvature, which is not an ideal method.

No other only because of the low forming accuracy of this method, the quality is not easy to control, in the overall processing not only requires skilled workers to operate accurately, but also after forming a large number of manual corrections by sheet metal workers, and the shot peening process mentioned by Director Qiao can well avoid the shortcomings of the rolling bending machine, not to mention, the strength and stress of the overall wall plate also have a good strengthening and elimination effect, which is the inherent advantage of the shot peening process. ”

"That's right, Ishi's right. ”

Qiao Chenyu glanced at Shi Jun approvingly, feeling that he had really picked up a treasure, with strong ability, willingness to work hard, extensive knowledge and understanding of enterprise management, such a compound talent is simply a role 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 do technical transformation, but Qiao Chenyu still didn't think he was better than others, you must know that many of the new college students have published professional papers, and the worst has also written technical improvement research in authoritative magazines.

Now among the group of people under him, Lin Guanghua is the worst, but he also has a paper and a technical article in hand, what does Zhuang Jianye have? nothing, oh, it's not right, Zhuang Jianye got the daughter of Minister Ning's family, and he can be regarded as capable.

But this kind of ability is really nothing in the eyes of Qiao Chenyu, who attaches importance to scientific research achievements, so this time the chief engineer asked him to set up a trial model research and development team during the meeting in Beijing, Qiao Chenyu took the public results as a hard indicator, and Zhuang Jianye was naturally excluded.

Of course, this is all off-topic, now as long as he gets the trial model in his hands and works hard, Qiao Chenyu doesn't believe that how bad these young men under him can be, what about the old man who has the organization minister, and those who have real skills are the way to go for a long time.

The thought flashed in his head, and the smile became more cordial and kind: "The shot peening process 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 Boeing, McDonnell Douglas and other powerful aviation companies, a single wing wall plate has to be twenty or thirty meters long, how big the roll bending machine can be processed, not to mention that even if there is, the inherent defects of the roll bending machine will also make this kind of parts defective, affecting flight safety."

As far as I know, the American B-52 bomber, Boeing 707, Boeing 747, DC-10 and other aircraft have applied this process, not only that, the new generation of combat aircraft in Europe and the United States have also applied the shot peening process, it can be said that this process has become the core process of the aviation industry, and has become the first choice for wing and tail manufacturing. ”

Lin Guanghua and others were quite stupid, they didn't expect this technology to be the core technology of European and American wing and tail manufacturing, not to mention them, even the knowledgeable Shi Jun was a little surprised, he knew that the shot peening process was very important, but he didn't expect it to be so important.

So the next moment, a fiery heart thumped, since Qiao Chenyu said so, and also pulled them to the first assembly workshop known as the "copper head", that is, they will participate in this research that is regarded as the core of European and American aviation powers.

Not only him, Lin Guanghua and others are aware of this, their faces are flushed, no matter what their selfishness is, the enthusiasm of aviation to serve the country has never been wiped out, if they can catch up with the world's advanced technology through their hands, it is the glory of their life.

Qiao Chenyu didn't say anything more, just quietly looked at the enthusiastic appearance of the group of young people in front of him, as if he saw the ambition and pride when he first entered the factory, nodded with satisfaction, spread out the technical information in his hand on the long table, and greeted: "Let's start now." ”

There were no magnificent slogans, no solemn ceremonies, and everyone understood that they were shouldering the burden of catching up from this moment on.

One by one, they immediately put in 12% enthusiasm and plunged into it.

Soon three days passed, Shi Jun and others, under the leadership of Qiao Chenyu, rearranged the information and analyzed the data in more detail, everything seemed to be very tense and smooth, as if a new spraying machine was about to come out.

But the more this is the case, the more Qiao Chenyu who is in the lead frowns, because behind the smoothness, several key data and structures make him unable to make up his mind, there is no way that these things appear too abruptly, there is no explanation, no argument, as if it jumped out of a crack in the stone.

Qiao Chenyu didn't care about it when he first found out, so he asked Shi Jun and the others to bypass it first, and then solve it after Chief Engineer He came back, after all, it was Chief Engineer He who led the way back then, and no one was more familiar with him than him.

However, with more and more abnormal data and structures, Qiao Chenyu's heart began to be calm, he was picked up by Chief Engineer He, and he knew very well that Chief Engineer He was a person, that is, rigorous, rigorous and not allowed any deviation, even if it was a decimal point, it had to be deducted reasonably, how could it be possible to make so many abnormal data and structures, but there was no detailed argument?

In order not to delay the progress, Qiao Chenyu had no choice but to suspend the theoretical research first, and let Shi Jun and others work the materials.

Then I waited for Chief Engineer He to come back and see if something went wrong that year.

He Ming rushed back to Yonghong Factory last night, came to the first assembly workshop early in the morning after a night's rest, stepped into the process room, and didn't say too much to Qiao Chenyu, so he picked up the information on the table and glanced at it a few times, then shook his head and said something that made Qiao Chenyu shocking: "I didn't do these data and structures." ”
