Scholars in the courtyard.

After going out, Shazhu looked at the moon in the sky, feeling the night wind in the countryside and the coldness of autumn that only belonged to the countryside, and couldn't help but shudder.

He lowered his head, rubbed his left and right forearms with his hands, looked at the potholed road, one was shiny and the other was black, then rubbed his cheeks and walked to the toilet at the entrance of the alley.

Running and jogging in two or three steps, Silhu was about to approach the toilet when he suddenly saw a familiar figure in front of him.

That look has already been etched in my mind during these days of work.

The other party just came out of the toilet and happened to bump into Silly Zhu.

"Jingru!"

This was the first time that Shazhu met Qin Jingru alone.

There was some trembling in the voice.

Needless to say, when he went to work before, he was surrounded by people. Even in private, it was not easy for him as a grown man to go to Qin Jingru, let alone Xu Damao by his side.

When Qin Jingru met Si Zhu, she lowered her head and was about to leave.

She has made up her mind to break up with Silly Zhu, and the bond between the two has been completely severed with the disappearance of the child.

But when she heard Shazhu's cry, Qin Jingru stopped involuntarily.

"Jingru, I, I always wanted to say sorry."

"It's me. I didn't take good care of you two. I'm sorry."

Silly Zhu stood aside, thinking of the past 'happiness', looking at Qin Jingru's back, feeling guilty.

Qin Jingru thought of her child, and tears flashed in her eyes.

However, she knew that at this moment, she was Xu Damao's wife.

Just walk away.

Silly Zhu watched quietly, and when he was about to go far away, he spoke out what was in his heart, "If he treats you badly, I will wait for you."

Qin Jingru paused and then disappeared into the alley.

Silly Zhu took a deep breath and then exhaled suddenly.

Lift your legs and walk into the toilet.

Siheyuan.

After Yang Xiaotao returned home, he also learned about the situation of the steel rolling mill in the past two days from the workers in the yard.

He was not surprised that the milling machine was built. After all, the drawings were ready and the people in the R&D department were all experienced. It was easy to build a milling machine.

But such a high-profile launch of diesel tractors is somewhat unexpected.

He had discussed it with Yang Youning and others before and solved the problem of the production line before launching it.

But now, can't you bear it anymore?

Yang Xiaotao thought about Yang Youning's temperament, and it was understandable that he couldn't help himself for such a big thing.

After all, who can hold back his excitement while guarding the honor he has received?
Being able to endure it until now, I guess a few people in the steel rolling mill are also panicking.

"It's just that, now that it's launched, are you ready for the changes?"

Thinking of the problems he might face, Yang Xiaotao had a lot of thoughts and always felt a little uncomfortable.

After eating, Yang Xiaotao came to the study, picked up a book, and slowly immersed himself in it without thinking about it anymore.

That night, there were some who fell asleep peacefully, some who couldn't sleep, some who tossed and turned and couldn't get what they wanted, and some who were thinking and planning.

Colorful nightlife constitutes a colorful world.

And all this, for Yang Xiaotao, every day when the sun rises, it is a brand new day.

After having breakfast, kissing his daughter, and then bidding farewell to his wife, Yang Xiaotao came to the steel rolling mill.

As soon as I walked into the gate, I saw banners started to be pulled up on both sides of the road to celebrate the successful production of diesel tractors. People from the publicity department were painting slogans, and workers walking on the road were talking to each other.

Everyone is very excited about the diesel tractor produced by the steel rolling mill.

So much so that Yang Xiaotao always receives warm greetings from workers on the road.

Yang Xiaotao did not return to the office, but went to the [-]th workshop to check.

In the workshop, Wang Fa had already arrived and was organizing workers to process the diesel engine.

Now there are two punch machines and a milling machine in the workshop, which are already in operation. The workers are working intensively on the drawings.

In addition, all workers originally used to produce steam engines have been converted to producing diesel engines. In other words, starting today, steam engines are no longer produced.

Of course, these people are only making parts.

These small parts are made by fitters, and one person can make dozens of them every day. With more people, the speed can be accelerated.

Finally, manpower will be organized to assemble the diesel engine.

"Boss, you're here."

Wang Fa saw Yang Xiaotao coming and hurried over.

"Brother Wang, what's going on?"

"Mr. Xia and Secretary Liu came to inspect yesterday."

At that moment, Wang Fa stated the demand for [-] units requested above, then stated Yang Youning's request, and finally talked about the current situation.

"The workshop still lacks a punch press and two milling machines. If the machines are in place and some manpower is organized, we should be able to achieve Director Yang's goal."

Wang Fa was not sure and could only speak vaguely.

Yang Xiaotao walked to the milling machine and looked at the workers operating the machine tool.

"Is this a piston?"

Yang Xiaotao looked at the parts being processed and asked.

The worker slowed down and opened the turning tool. At this moment, two circular grooves of different depths appeared on the component. Yang Xiaotao took a look and knew that this was making a gas ring.

"Director, yes, we mainly use this milling machine to process the three rings of the piston."

The worker said and Yang Xiaotao nodded.

Then he walked aside, picked up the piston head he had just made, and shook his head at a glance, "If the air ring is shallow, it will affect the air ring movement, but if it is deep, it will affect the air intake. This is a delicate job." .”

"Look at these two circles. One is deep and the other is shallow. They obviously do not meet the requirements."

The worker looked at the finished piston and his face turned red.

He felt that the one he had just made was okay, but after hearing what Yang Xiaotao said, it seemed like it was not working anymore.

Wang Fa on the side sighed, "This is the difficulty we face."

"The machines have kept up, and the materials have kept up, but they can't make qualified parts."

"If we pursue quality, I'm afraid it will affect the progress. But if we don't relax the requirements so much, let alone four thousand five hundred, even one thousand five hundred will be difficult."

Yang Xiaotao didn't say anything. He was also thinking about whether he wanted quality or quantity.Because of Yang Youning's high-profile announcement, the whole country now knew that the steel rolling mill produced a diesel tractor.

The whole body is made in China.

But it would be a joke if we knew that the steel rolling mill's production capacity was insufficient.

"Does the superior have any other requirements?"

"I didn't say it."

Yang Xiaotao nodded, and then checked the work situation in the workshop.

Most people had just come over from steam engines and were not yet skilled in the work on their hands, so making parts was not satisfactory.

As for the team that assembles the diesel engine, they are also taking the time to familiarize themselves with the process, and people who have previously participated in the production are teaching.

Yang Xiaotao listened for a while, then turned and left the workshop and returned to the office.

As soon as he sat down, he was called into the office by Yang Youning's secretary Xiaoqiang.

In the room, Yang Youning had dark circles under his eyes. When he saw Yang Xiaotao coming, he rubbed his brows and pointed to the chair in front of the table, "You know what happened, right?"

Yang Xiaotao sat down and nodded, "I heard, fifteen hundred units, every month, this is not a small amount."

"Yes, but Mr. Xia's death order must be fulfilled."

Yang Xiaotao nodded. The task is the task. You can only find a way to complete it, otherwise it will be the mistake of the steel rolling mill.

"I went to the workshop and saw that accuracy and quality were an issue."

"Unless you find experienced workers to operate it, it's not as good as manual processing."

"But then efficiency will suffer."

Yang Xiaotao told what he saw, and Yang Youning sighed again, "I know this, but to get through the difficulties now, we can only hand over some parts to other workshops. Each workshop can give a little bit, so that other tasks can be completed. , and it can also reduce the pressure on the [-]th workshop.”

"This is also possible, especially the small things, which can be disassembled and distributed to various workshops."

Yang Xiaotao agreed, "However, I think we still need to strictly control the quality."

"You also know why the Red Star tractors produced by our steel rolling mill are so popular. Let's look at the tractors from other factories. It's because of their good quality and solid materials."

"Steam engines in other factories will break down after half a year, but ours can last for one year, or even two years."

"The reputation we finally built up cannot be ruined because of sloppiness."

Yang Xiaotao still reminded that many of the best designs these days are due to lax quality control. Although everything is planned and everything produced is completed, Yang Xiaotao still wants to maintain the credibility of the Red Star brand.

Yang Youning nodded.

As for other methods, the two of them don't know much about it. They will wait until they think of it.

Back in the office, Yang Xiaotao looked at the neatly arranged desktop and didn't know what to do.

In the workshop, the tractor was watched by Wang Fa and others, and Chang Mingjie was still arranging production at the machine tool. As for other places, there were also people taking care of it, so he felt relaxed.

So, Yang Xiaotao found a book and read it in the office.

The pace of life suddenly slowed down.

When I returned home in the evening, Ran's father was watching the Dragon Boat Festival play in the yard. The old Taoist next to him was holding a pot with a handle, and the two of them were talking about each other.

Xiao Wang looked at Wangcai and kept teasing him, but Wangcai ignored him at all.

In the house, Ran's mother was cooking with Ran Qiuye, while the twins were being watched by Ran Xinrui and her brother.

Yang Xiaotao walked in, greeted Ran's father, and went to the house first to see if he could help. Ran's mother asked him to just keep an eye on the child, so Yang Xiaotao came to the house, saw Ran Xinrui and asked about the school situation, knowing that she was in the morning class , there is no class in the afternoon, so you can go home.

He held the two girls one by one in each hand and put them into the trolley, and then they left.

"Dad, I'm old."

Yang Xiaotao listened for a while, chatting about past events, and then stepped forward to say hello.

"came back!"

Ran's father looked back, Yang Xiaotao nodded, and then said, "We encountered something difficult."

"Huh? What's the matter."

The two became interested. Yang Xiaotao was quite capable. He said it was difficult, so it must be extraordinary.

"You two know that the rolling mill has developed a diesel engine, but now there is a problem."

After Yang Xiaotao finished explaining the matter, both of them began to think deeply.

“This kind of thing needs to be done either with people or with machines.”

The veteran just thinks briefly and puts forward his own opinion.

"Yes, we have already added more people here and even handed over some bits and pieces to other workshops."

"But it's not a long-term solution."

The veteran nodded, "That's a technical improvement."

He said, stroking his beard, "Either improve the structure of the diesel engine to make it more suitable for production."

"This single-cylinder diesel engine is already a very simple structure. No matter how simple it is, all that is left is the cylinder."

"Then improve the manufacturing machinery."

"Machines, punches and milling machines? How can this be changed?"

The old Taoist shook his head, "I'm just saying this direction, it's up to you how to change it."

Yang Xiaotao was speechless, this guy was just a painter.

"Xiao Tao, don't tell me, I really have a way." Suddenly Ran's father spoke, which shocked Yang Xiaotao.

"Dad, what can you do?"

"Last time you gave me those two books to study how to improve machine tools. I read them and they contained explanations about semi-automation of machine tools."

"Semi-automatic?"

"Yes, it is semi-automation. Although this part of the knowledge is decades ago, it is still blank for us."

"Dad, did you bring the book?"

"Take it with you, right in the house."

After Ran's father finished speaking, Yang Xiaotao directly asked Lao Tao to help look after the child, and the two quickly walked into the study.

Ran's father sat down, opened the book on the development concept of advanced machine tools, found a drawing, and pointed it out to Yang Xiaotao, "This is the semi-automatic machine tool made in Germany in the 30s and [-]s."

"It is proposed in this book that the workbench can use the stopper to achieve fast-feed and feed-fast conversion under the action of the milling cutter"

Yang Xiaotao walked up and looked at it for a while. Although he couldn't understand the text on the drawing, some graphics could still be seen.

As Father Ran explained, Yang Xiaotao quickly thought about how to accomplish his goal, picked up a pen and paper and started drawing on the table.
