Chapter 102 Refining Various Aircraft Carriers
Hu Yang turned his head and saw a stranger behind him, but he was not particularly surprised.For this research, the Light and Chemical Department sent several engineers, Hu Yang naturally regarded Yan Yuanhe as one of them, he explained:
"The several special-shaped surfaces of this shaft are not for good-looking, but each has its own function. Starting from its function, its curve can be deduced. It's just that the calculation of these curves is more complicated. Xiaolin and I It was calculated using the finite element method, otherwise it would not work.”

"Do you understand finite elements?" Yan Yuanhe was a little surprised.

Hu Yang nodded, pointed to Lin Zhenhua and said, "He is my teacher."

Lin Zhenhua shook his head quickly: "Comrade, don't listen to Lao Hu's nonsense, he is my teacher now."

Yan Yuanhe naturally didn't believe that Lin Zhenhua was Hu Yang's teacher. Judging from the conversation between the two of them just now, it seemed that Hu Yang was more spiritual.He said to Hu Yang: "Your name is Hu Yang, right? When your research project is over, I would like to ask you to come to our place to guide the work. We have many complicated calculation problems, so we want to find an expert in finite elements. "

"What do you want?" Hu Yang asked in surprise.These factories in the light and chemical department system mainly produce some products that have been finalized, plus some daily equipment maintenance and other work, it seems that there is no need to involve complicated calculations.

Yan Yuanhe took it for granted, "Of course it's ballistic. What else can we count?"

Hu Yang was startled: "Comrade, where are you from?"

"He is the technical section chief of Changhong Factory, Comrade Yan Yuanhe. This time the rough parts were delivered by him personally." Zhu Tiejun introduced later with a smile.

"Oh, Section Chief Yan, welcome." Hu Yang quickly shook hands with Yan Yuanhe, with an expression of respect and distance on his face.

Yan Yuanhe didn't take it seriously. After shaking hands with Hu Yang, he said, "How about it, Comrade Hu Yang, let's make a deal like this, shall we?"

"This, let's think about it in the long run." Hu Yang quickly flashed, "I'm not suitable for things related to military industry, hehe, me, my family background is relatively high..."

After all, without waiting for Yan Yuanhe to say anything, he dragged Lin Zhenhua back to the computer.

Yan Yuanhe watched Hu Yang run away, turned to Zhu Tiejun and asked: "What, Comrade Hu Yang, do you have any political problems?"

Zhu Tiejun said: "I have also read his files. It seems that his family is a middle peasant, which is not very high. Personal experience is very ordinary. He stayed in two factories before being transferred to Hanhua factory. I came here. I have been in the factory for more than ten years, and there is no bad record. During the turbulent years, I did not join any faction and belonged to the Xiaoyao faction."

"It doesn't matter to the middle peasants." Yan Yuanhe said, "Actually, the requirements for political review have also been lowered now. Isn't the theory of blood lineage created by the Gang of Four? We don't like this anymore."

Zhu Tiejun said: "Old Hu may have suffered some shocks in the original factory, so he has some after-effects of exercise. You should understand this, right?"

Yan Yuanhe said: "Of course I understand, there are too many people who have this kind of thinking. How about this, after I go back, I will ask the National Defense Industry Office to send a letter directly, formally inviting him to come to our side to help for a few days , so that he will not have any mental burden."

Zhu Tiejun said with a smile: "You Yan Section Chief, you really don't have any benefits. I said that you came here to send us rough parts with such good intentions. It turns out that you are holding back to poach our corners."

Yan Yuanhe sighed, and said: "Director Zhu, you don't know, we are also in a hurry. Now the army is clamoring to update the equipment, and we are under great pressure. However, there are only so many technicians, and the age The Internet is also weak. The foundation of the younger generation is too weak to take key tasks. The knowledge of the older generation is too old. Apple computer, but very few people know how to use it, unlike you, any woodworker can use it."

His last sentence was said with a smile. Of course, he also knows that wood model workers like Hu Yang are different. If the workers in the entire Hanhua factory have this level, then this is not a Hanhua machinery factory. , but Hanhua University.

After Yan Yuanhe delivered the blank, he stayed in Hanhua Factory, and followed Lin Zhenhua and others to think about spindle processing every day.Yan Yuanhe himself was a college student in the 50s, and his foundation was also very good. He was able to put forward good opinions on many issues, so he gradually became familiar with everyone.

The processing work has finally started, and the early stage is some very routine processing.First mill the end face with a milling machine, drill a center hole at both ends, and then use the center hole as a positioning reference to roughly turn the outer circle on a horizontal lathe.After this step is completed, it is a heat treatment process, the surface is quenched and tempered, and then semi-finishing is done, and the contour of the spindle is turned.This process is not difficult for Hanhua Factory. However, in order to ensure the quality, Luo Qinsheng specially appointed two high-level machine tool workers, Peng Gang and Zhou Houcheng, to operate it.

After the semi-finishing is completed, the rudimentary main shaft is subjected to heat treatment again, and the surface is quenched, and then enters the stage of finishing.

The most difficult and exciting part of finishing is the process of imitating five-axis machining.After arduous calculations, Hu Yang and Lin Zhenhua obtained the envelope equations of each special-shaped surface, and then cooperated with Wei Jingwen to transform the equations into the coordination relationship of the four axes on the machine tool.

Peng Gang and others have already experienced this process. The process document written by Hu Yang is very clear. All they have to do is to accurately position the workpiece according to this document, and then with the assistance of the linkage-related fixture, Curves are cut one by one, and a specified surface can be formed as a result of several curve cuts.

"It turns out that this is how you realize five-axis machining." Yan Yuanhe stood aside, looking at it in a relaxed and happy manner.As a technician of the military system, his understanding of five-axis machining is even better than that of Hanhua Factory.

"Strictly speaking, we only have four axes, and the operation of the fifth axis is done manually." Lin Zhenhua corrected him and said, "Our calculations can reduce the number of re-clamping and positioning from infinity to an acceptable level. Then it’s up to the worker to re-clamp multiple times to complete the cutting of each face.”

"It is already very remarkable to be able to do this." Yan Yuanhe sighed, "Unexpectedly, the highest processing level will be here with you. I don't know if the military industry systems in other places can do this. At least, within the system of the National Defense Industry Office of Jiangnan Province, there is no company that can do this."

Lin Zhenhua laughed and said: "Chief Yan, our technology is not confidential. If your military system needs five-axis machining, we can do it for you. But, in terms of the cost, we still need to charge a little. You see How about it?"

Yan Yuanhe asked half-jokingly: "How do you charge this fee, can you tell me?"

Lin Zhenhua came to his senses, and he said to Yan Yuanhe with his fingers: "Our charges are very reasonable, and the charging items are also very clear. You see, it mainly includes design fees, computer time fees, machine tool technical transformation fees, and man-hour fees. , electricity costs, material costs, machine tool wear costs, site occupancy fees, missed meals, education surcharges, family planning..."

"You little Lin!" Yan Yuanhe was amused by Lin Zhenhua. After these days, he already knew that Lin Zhenhua was a living treasure, and he would do weird things from time to time.After laughing, Yan Yuanhe asked in a low voice: "Xiao Lin, you really haven't thought about working in our system? As a special industry, our salary is one level higher than that of the local government."

Lin Zhenhua shook his head vigorously: "No, no, Section Chief Yan, don't get me wrong, I've already got my name."

"What about Lao Hu? I heard that you have the best relationship with him."

Lin Zhenhua said: "Old Hu, I advise you not to make up your mind. I talked to him, and he said that he doesn't want to go to your side. He has his own difficulties. You should not force others to make things difficult for you."

In fact, Lin Zhenhua hadn't discussed this issue with Hu Yang in the past few days, but he knew that since Hu Yang rejected Yan Yuanhe's invitation, he must have his own ideas.Lin Zhenhua has always had a guess that there must be something hidden in Hu Yang's life experience, otherwise, as an outstanding person like him, he should not be buried in this small Hanhua factory.Populus euphratica is by no means a thing in the pond, a Changhong Machinery Factory should not be able to accommodate a big dragon like him.

"It's such a pity." Yan Yuanhe said.He had tried Hu Yang several times, but every time Hu Yang flatly rejected him.

Of course, Yan Yuanhe also thought about poaching Hu Yang away through the organizational procedures, but after thinking twice, he gave up this idea.The melons twisted by force are not sweet, if Populus euphratica cannot be made to go with him willingly, even if he gets over it, he will not be able to play a role.Besides, Hu Yang belongs to the Qinghua Department system. Although the military has certain powers, if the Qinghua Department refuses to release him, it will be troublesome enough to have to fight in the middle.

"Section Chief Yan, I'm serious with you." Lin Zhenhua said, "The times are different now. In developed countries, military industry and civilian use are not separated. Isn't Boeing in the United States just for military and civilian use? If the country's national defense industry wants to develop, it cannot build a car behind closed doors, but should actively cooperate with the civilian industry. You can consider the things I mentioned earlier that can be processed for you. In terms of cost, we will definitely not open the door .”

Yan Yuanhe nodded: "I understand what you mean. After I go back, I will report to the leader."

"Okay, I'm waiting for your news."

Lin Zhenhua felt joy in his heart, he didn't expect that he could inadvertently catch the line of the military.Since he developed the imitation five-axis technology, he has been thinking about how to transform this technology into a means of making money.You must know that under the condition that Western countries block the five-axis linkage technology from China, if he can provide this kind of imitation five-axis processing service, then it is possible to charge any sky-high price.

Think about it, didn't Xie Chunyan let go of this time when the light and chemical department organized a breakthrough, saying that it could be afforded within 3 yuan?This is just a spindle with a cost of 300 US dollars. According to the labor cost of the Hanhua factory, it is estimated that it will not even cost 300 yuan. This is a hundred times the profit.

Five-axis machining, an artifact of this kind, does not currently have a large market in the civilian field in China, but it is hard to say for the military.

Otherwise, I will put an advertisement on TV tomorrow: Hanhua Industrial Co., Ltd. provides high-precision multi-surface processing services, intensively repairs intercontinental missiles, various aircraft carriers...

Thinking of this, a harmless smile appeared on the corner of Lin Zhenhua's mouth.
