Siheyuan: I can simplify skills

Xu Damao walked outside and looked at He Yuzhu.

Both of them had complicated expressions.

Then they each hummed and went back to their homes.

In the original work, this year, He Yuzhu originally wanted to make a fool of himself by asking the three Banggeng brothers to go to various houses to sing and count treasures in order to extort new year's money.

But now that the relationship between He Yuzhu and the Jia family has deteriorated, He Yuzhu will naturally not instigate the three brothers and sisters.Of course, the scene in the original play never happened.

But on this day, Yi Zhonghai responded to the call of the street and held a group meeting in the yard.

"From now on, when we celebrate the New Year in the courtyard, we won't go to each household one by one to celebrate the New Year. We will hold a group gathering in this courtyard.

Because it was the Spring Festival, melon seeds and peanuts were placed on the table.

The three uncles sat at the table and kept eating melon seeds.

"New people, new things, new country. In response to the street call, from now on we will pay New Year greetings in the courtyard instead of visiting each house. We will express our best wishes for the New Year to each other in the courtyard." Yi Zhonghai said.

Yan Bugui said this method is very good, mainly because he can save a fortune.

The children are a little frustrated. If they don't visit each house, they will lose their New Year's money and they won't expect to get candies.This is a really bad new year.

It doesn't matter to the adults. It's better if they don't visit each other. They don't have to put out the candies at home, and they can still make a small fortune.

Mr. Jia and Zhang were a little displeased. They had many children and visited each other, so their family was guaranteed to make a profit.The ones who suffer are old people like Yi Zhonghai.

But Banggeng no longer looks down on the little New Year's money.He had a dozen dollars of pocket money in his pocket.This is already considered a nouveau riche among his peers.

Singles like He Yuzhu and Xu Damao are also very happy.Xu Damao was stingy to begin with, and he was never willing to do anything that would result in a loss.

He Yuzhu's temperament has changed drastically now, and he has begun to worry about these things.

Xu Yang didn't care.By not visiting, he saves trouble.

You can also sit quietly at home and brush up on your skills.

The data room at Beihang University would not open for another two days, so Xu Yang could only brush up on the skills he had previously reserved at home.

In fact, with Xu Yang's current capabilities, he is not inferior to researchers who are currently developing fighter jets.

According to the historical process, the research and development of the J-8 has already begun.

In the course of history, the development process of the J-8 was very long.By the time it was finally developed, produced and equipped, the J-8 was already lagging behind.

The J-8 was originally designed as a jet piston engine fighter.But by the time the J-8 began to be equipped, the third-generation aircraft from the United States had already been equipped on a large scale.

If Xu Yang can design a turbine engine and it is adopted by the J-8, it is very likely to speed up the early equipment of the J-8.

However, even if the design drawings are available, the steel rolling mill does not yet have the ability to produce aviation engines.We still have to wait until Xu Yang designs a new generation of machine tools.

Xu Yang's current design capabilities and knowledge reserves have improved a lot compared to before.Now let’s design this new generation machine tool. It is much more perfect than before, and the accuracy will be greatly improved.

On the first day of the new year, while others were still immersed in the festive atmosphere, Xu Yang had already started working.

One after another very exquisite design drawings were drawn in Xu Yang's pen, and Xu Yang completely forgot about time.

In the design of a new generation of machine tools, there are still several important issues that need to be resolved beyond the mechanical aspect.

The new generation of machine tools is actually a data-controlled machine tool.Xu Yang must solve the problems of microelectronic systems, integrated board circuits, and semiconductor components.

Many of these things cannot be solved at home, and we need to find ways to get them from abroad.

Chapter 120 Material is King

With Xu Yang's current advanced skills in microelectronics, semiconductors, integrated circuits, etc., it is not impossible for him to do these things from scratch, but it will take a lot of time.

Unless relevant domestic industries can cooperate with him, these domestic industries are still in their infancy, and the gap with foreign countries is very large.It developed decades later than others. How can it be possible to catch up now?

Waiting for Xu Yang to turn around and bring up these industries, the day lily will really be cold.

Therefore, Xu Yang still has to find a way to make a new generation of machine tools first.Machine tools can solve many practical problems.

For example, the processing problem of aviation precision parts.

Of course, if you want to process precision parts for aircraft engines, especially if you want to skip the jet piston aircraft engine and directly design the turbine aircraft engine, you still need to solve the material problem.This is another problem.Xu Yang can solve it, but Xu Yang is also needed to drive the leapfrog development of the materials industry.

Xu Yang shook his head and didn't want to think about so much.Make the design drawings first.

The residents of the courtyard house have been busy visiting relatives and friends these days, and every household is full of laughter.

Only Xu Yang's house was deserted.He is either drawing pictures or practicing skills every day.It feels even curlier than before the time travel.

But I feel very solid every day. There are more and more drawings every day, and there are more and more perfect skills.

Materials science, engineering mechanics, heat transfer, microelectronics engineering skills, semiconductor technology, integrated circuit technology, electrical engineering, mathematics, physics, chemistry and other skills have been gradually improved to perfection.

During this short vacation, Xu Yang has undergone a transformation.

Soon the rolling mill holiday was over.

The employees of the steel rolling mill returned to the factory.

Xu Yang also returned to his office.All the drawings at home were moved back and piled up in a pile.

This time there are several times more drawings than the previous machine tools.It can be seen that the machine tools this time are much more complex than before.

"Xiao Xu, there are so many drawings? Isn't the design completed yet?" When Secretary Yang came over to learn about the situation, he was shocked by the pile of drawings on the table.

"It's not even close. The machine tool this time is much more complicated than the previous one. Strictly speaking, the design this time is not called a machine tool, but a machining center. It can process many precision parts. By the way, Yang Secretary, there are still many accessories that need to be purchased from abroad. In addition, I also need to find the department that makes lathe tools to cooperate. I need to improve the materials of the tools. Otherwise, with the quality of our previous tools, we will not be able to perform machining. All the functions of the center are available," Xu Yang said.

"Don't worry, the factory will do everything possible to provide any accessories I need. For metal materials, our factory itself has equipment, but it has been idle there. If you need it, I will invite experts from outside the factory to help. Secretary Yang said.

"There is no need to invite experts. I have just studied a few recipes myself and am ready to try them. I should be able to barely run those machines. I will just find some people to help me. However, it is still early, and I still need someone to get the drawings. It will take a month to complete it," Xu Yang said.

Xu Yang handed over the list of items that needed to be purchased from abroad to Secretary Yang.The purchasing department in these material factories is not competent and can only be solved through the department.

If it weren't for the fact that Xu Yang had continuously designed machine tools with excellent performance and had been registered with the ministry, Xu Yang would not have even thought about purchasing so many accessories from abroad this time.Except that Xu Yang solved it through Professor Wei.

At this time, Xu Yang was busy drawing design drawings in the office, and no one dared to disturb him during working hours.I'm afraid it will delay Xu Yang's time.Only when it was time to eat, Guo Dabozi and Zhao Xiangdong would take turns delivering food to Xu Yang.

Xu Yang's meals are all small pot dishes specially arranged by Secretary Yang to be cooked in the canteen.There are several dishes every day, and I have also thought of ways to deliver meals.A very special three-layer lunch box was specially made in the workshop.Each layer has two compartments, which not only keeps the food warm but also allows Xu Yang to eat more dishes to ensure nutrition.

"Master, why don't you eat something here too," Xu Yang said.

"I don't dare to deprive you of food. If I eat with you, my dear, more than 1 employees in the steel rolling mill will have to skin me." Zhao Xiangdong laughed.

"But I can't finish all this food by myself. Please go back and tell the cafeteria that you don't have to cook so much for each meal. Two dishes at most are enough. You can also eat less. I'll stay here every day. I haven’t gone out, and if this continues, I’m worried that I’ll be too fat to walk in the future,” Xu Yang said.

"Then you should walk around appropriately every day, otherwise your body will collapse." Zhao Xiangdong said worriedly.

"Don't worry about this, Master, it's okay. I'm in good health. Besides, whenever I have free time, I'll box all the way. This consumes a lot of energy. If I really do something good, this little food won't be enough for me." Xu Yang laughed. road.

"Then you should work hard and eat all this food every day, so that Secretary Yang won't worry about your nutrition. To be honest, you have made such a big contribution, and the factory cannot overemphasize it. You No one in the steel rolling mill has any objections to eating better," Zhao Xiangdong said.

"Okay, okay, I'll finish. I'll finish. I have to speed up this time. The complexity of this machine tool is much greater than I expected. This machine tool alone will be equivalent to our current improvement workshop in the future." A whole workshop." Xu Yang said.

"So powerful?" Zhao Xiangdong was very surprised.

"I dare say that when this machine tool comes out, it will not be said to be the most advanced in the world, but at least it will be at the top level in the world. It's just that it's not easy to build this machine tool." Xu Yang said confidently.

"Why should we be afraid of the difficulty? What difficulties have our improvement team not experienced? Why not make progress little by little? Our improvement workshop will definitely be able to create miracles." Zhao Xiangdong's trust in Xu Yang has now reached an extreme level.

Xu Yang worked overtime to design, modify, and optimize the project, bringing the estimated time much earlier.After the design drawings were completed, he did not immediately hand them over to a workshop.

Because he is planning to upgrade the materials used in the machine tools.In addition, the cutting tools of the machine tools in the improved workshop need to be upgraded, otherwise the new materials cannot be processed, let alone the accuracy required by the new generation of machine tools.

The steel rolling mill has a metal smelting workshop, but it has been idle. The equipment was imported from Damao during its construction assistance period.Later, after the Da Mao experts withdrew, the smelting workshop was unable to resume use due to a lack of experts.

"The equipment has been maintained and maintained, and it looks like new. In fact, it is new. When Da Mao's experts were here, they just debugged it. It was not officially put into production. It was originally planned to be moved to Beigang, but because of The equipment was too bulky and difficult to dismantle. If it was dismantled, it would most likely turn into a pile of scrap metal. So it was simply left idle here." Secretary Yang took Xu Yang to the metal smelting workshop that had been idle in the steel rolling mill.

"This equipment has completely fallen behind. I need to carry out technical modifications before it can be put into use again." Xu Yang said.

"Go ahead and transform it boldly. Even if it fails, don't worry. I have already submitted it to the ministry for approval. The big boss said that you can use it with confidence and boldness," Secretary Yang said.

Xu Yang is not worried that the technical transformation will fail. With his current level, it is really very simple to carry out technical transformation of the equipment here.

The equipment dimensions were measured on the spot, design drawings were drawn on site, and the required parts were handed over to the improvement workshop for processing.

The improved workshop completely stopped all processing tasks and fully met Xu Yang's needs.

Secretary Yang dispatched a group of fitters from other workshops to help Xu Yang dismantle and modify the equipment in the smelting workshop.It was almost in the past few months that Xu Yang completed the renovation of the smelting workshop and the equipment operation training.

The most capable assistants, Zhao Xiangdong, Guo Dapizi, Lao Xiao and others were also pulled over from the improvement workshop.

"Lao Guo, get ready to start the equipment!" Xu Yang said.

Guo Dabizi nodded: "Attention to all workstations! Turn on the equipment in order. Be sure to follow our rehearsal plan! Everyone pay attention to safety! Prepare, turn on 3,2,1, [-], [-]!"

Following Guo Dapizi's order, various equipment in the smelting workshop were turned on one after another.The smelting furnace soon turned red, and the temperature inside was getting higher and higher.The metal put into it begins to melt, and then fuses into special metal materials through the process set by Xu Yang, and finally becomes the shape Xu Yang needs in the mold made by Xu Yang.

Then through various processes, the special metal materials needed by Xu Yang are obtained.

Xu Yang wants to process multiple special materials to manufacture a new generation of machine tools he designed.The most important of these are the cutting tools of the machine tool.

In fact, it is not a big problem whether special metals should be used for other parts.But the knives must be made with the new formula brought by Xu Yang...

After the tool goes through a series of processes, it becomes a finished product.

This first batch of tools was specially prepared for the improvement shop's machine tools.After the machine tools in the improved workshop were replaced with these tools, they were able to process parts for the new generation machine tools designed by Xu Yang.

Guo Dapizi picked up a processed tool and said: "The workmanship of this tool looks much better than that produced by Beigang. The quality of the tools produced by Beigang is really hard to describe, and it is really much worse than the original tools produced by Da Mao." That is to say, there is really no other way, otherwise I really don’t want to use their knives. Sometimes if I’m unlucky, I have to change the knives once a day. After using them, the knives are almost worn out.”

Zhao Xiangdong also took it over and took a look: "It looks really good, but I don't know how hard it is."

"Just take it back and give it a try. The batch of special workpieces from key units are very strong. Sometimes you have to change the tool when processing one workpiece with Beigang's cutting tools. Take our cutting tools and try them out to see the degree of wear and tear, which one is better? Isn’t it clear that it’s bad?” Guo Dapai said.

Several people took the tools and ran to the improvement workshop.

Just remove the cutting tools from several machine tools on the assembly line and replace them with new ones.

"Bring the special artifacts here!" Guo said.

The special workpiece was brought over on the spot, fixed with a clamp, and then the machine was started for processing.

This time, the processing process was extremely smooth, and the special workpiece was like tofu, with the new tool easily turning away the excess parts.

"Lao Zhou, you can still eat a little thicker. The hardness of this blade is much stronger than that of Beigang. There is no need to sharpen it bit by bit." Guo Dabo said.

"Aren't you afraid that the blade will break?" Lao Zhou asked.

"Don't be afraid. If it collapses, it will collapse. Anyway, we made it ourselves. I just want to see where its limits are." Tuo Dashouzi said nonchalantly.

Lao Zhou simply adjusted the size directly.If it is normal, it must not be adjusted like this. Once it cannot be eaten, it will definitely cause the workpiece to deviate, and ultimately lead to processing failure.

This time, there was no impact at all. The tool penetrated deeply, and the metal parts were scraped off piece by piece as if they were mud. When the processing was completed, the time was less than one-tenth of the previous time.
