Scholars in the courtyard

Several people came to the workshop. Yang Xiaotao looked at the row of machines in front of him and took two steps forward. Many of the machines were not running, but there was no dust on them, so they were obviously well maintained.

"Director Yang, this is our best machine. Even though they are a little old, they are even older than the workers here, but they are not bad at using them."

"This one belongs to Lao Maozi. Although it's a little rough, it's not bad for use."

"I had this one when I came here. It's from France. It's a bit delicate and will cause problems if you don't work on it. But when it's good, it's finely processed, so I point to it."

"and this…"

Fangyuan introduced the machine in the workshop, and Yang Xiaotao looked at it and nodded from time to time.

After a while, many people came to the whole workshop. Some of the old workers at the front were wearing gloves. After listening to Ma Xiaoling's words, they all came over to see if Yang Xiaotao was really capable.

"Comrades are all here, let me introduce two important guests to you."

"Chief Wang, everyone is welcome."

Although people here are not familiar with Wang Huzi, they have at least seen him.

Wang Beard waved his hand but said nothing.

"this."

Director Fang walked up to Yang Xiaotao.

"This is Comrade Yang Xiaotao from Hongxing Steel Rolling Mill in Forty-Nine City."

"This comrade's ability is not small. If he had to talk about it, it would take a long time. I won't brag here. If you are interested, you can ask Team Leader Ma."

Hahaha

Yang Xiaotao also laughed, getting used to Director Fang's humor.

"Now that the introduction is over, let me tell you the specific situation."

Fangyuan glanced at Wang Huzi and Yang Xiaotao, and then said seriously, "The chief has brought us a new task, an arduous and glorious task."

"A seat belt is a belt installed in a car. If a driver has it, he can survive."

"Is everyone confident that it can be completed?"

"have!!!"

"Make sure to complete the mission."

When everyone stopped talking, Director Fang looked at Yang Xiaotao.

At this moment, Yang Xiaotao also understood Wang Huzi's intention in asking him to come.

Since he has to show off his skills, Yang Xiaotao will not be humble.

Besides, if he can really help, he won't be stingy.

Rolling up his sleeves, Yang Xiaotao walked to a blackboard and picked up the chalk next to it.

Many people around him took out their notebooks to prepare marks, while Wang Huzi and Xiao Wu gave up their positions.

"Comrades, the safety belt we are going to make is divided into two parts. The belt and the fixed part. The fixed part contains the retractor, central part, internal gear and clamping wheel."

As Yang Xiaotao spoke, he drew each component on the blackboard.

This tests one's painting skills, or design skills.

Everyone watched as the parts on the blackboard were rapidly formed. Yang Xiaotao even wrote names and data on the side for everyone to record.

After all the drawings were finished, Yang Xiaotao began to introduce the design and structure of the seat belt.

"Under normal conditions, the seat belt pulls the safety rope slowly and the rollers inside move at a constant speed. At this time, the seat belt will not get stuck."

"But if we apply an external force and pull the safety rope quickly, the roller will rotate rapidly. At this speed, the clamping wheel inside will deviate and be clamped by the internal gear."

Yang Xiaotao pointed to the place where the internal gear is clamped, "In this way, the rotating shaft will stop rotating and the rope will be tightened to achieve safety."

"In this way, it is enough for everyone to have an impression. Next, I will give you an example so that everyone will know how to do it."

As he spoke, Yang Xiaotao walked to the bench next to him, looked at the tools on the bench, and then started to prepare.

Ma Xiaoling stepped forward to take action, and the people around her gathered around again. Some people couldn't see it outside, so they looked for stools. Two or three people pulled them and put one foot on them to watch.

Others just find a machine and stand on it, looking towards the middle.

Fangyuan did not step forward. As an eighth-level fitter, he could tell by looking at Yang Xiaotao's graphic psychology.

"Chief, this."

"What, are you excited?"

Wang Huzi knew what to say by looking at Factory Director Fang's expression.

"You have seen all this."

Director Fang pointed to the picture drawn by Yang Xiaotao, "I dare not say anything else about this skill and the ingenuity of the design. There is no one like it in the northwest."

"Oh? Do you think so highly of him?"

"Hey, once an expert makes a move, his colleagues know best. Look at the picture drawn and the data marked, tsk tsk."

Director Fang sighed with emotion, and finally came forward, "Can you?"

"cannot!"

"Oh, I'm still thinking about quitting."

"Come on, just be satisfied if you can call me here. It will be difficult for this guy to come here in the future. I only give you three days, so you have to seize the opportunity."

Director Fang opened his mouth and nodded silently.

"By the way, the order for this seat belt will come out in two days, so you should hurry up."

Director Fang immediately had a smile on his face, "Don't worry, we won't delay anything."

I was thinking that if I get it done this time, I will have all the things for the New Year.

At this time, Yang Xiaotao has already entered working mode.

That feeling, the moment you touch the tool, the muscle memory of your hands has been awakened, and you are instinctively familiar with the tool.

The data of each component of the seat belt appeared in my mind, and then I started to do it.

呲呲

squeak

The monotonous sound echoed throughout the workshop, and everyone watched nervously, not daring to make a sound.

Ten minutes later, everyone looked at the completed parts one by one, and then found springs and straps. Yang Xiaotao began to assemble the seat belt on the spot.

"Pull slowly!"

Yang Xiaotao held one end, and Ma Xiaoling held the other. With slow pressure, the strap was pulled out half a meter long.

"Harder!"

Click

I saw that Ma Xiaoling had just pulled hard for less than three centimeters when she heard a jamming sound and she could no longer pull.

"Relax and pull slowly."

As Yang Xiaotao said, Ma Xiaoling let go of the belt, slowly pulled it again, and this time it was able to be pulled out.

People around me finally understood why it was called a seat belt.

"Does everyone know how to do it?"

"Okay, I understand."

Everyone was talking and the atmosphere was lively.

When Director Fang saw it, he walked up to Yang Xiaotao, took the seat belt and took a closer look.

As soon as the thug tried it, Director Fang sighed in his heart.

This craftsmanship is no worse than my own youth.

"Why are you laughing? They say that outsiders only watch the fun, while insiders watch the door!"

"Look, look. Are you just watching the excitement?"

The shouts in the workshop suddenly stopped.

Director Fang looked at everyone, then put his finger on the central axis, flicked it with his right hand, and the seat belt rotated on his finger.

The speed was neither fast nor slow, but it took a long time.

Everyone saw this and were shocked in their hearts.

In this case, if the design is not accurate and the production is sophisticated enough, this effect will not be achieved at all.

Director Fang, who held it in his hand, was equally shocked.

The hand is stable, and there is no need to balance it by yourself, because the center of gravity is on it.

"Ma Xiaoling, look, can you do this?"

With that said, he called Ma Xiaoling who was nearest.

After Factory Director Fang shouted, the previously excited workers immediately became silent. Ma Xiaoling looked carefully at the finished safety belt, especially the internal structure, with a serious look on her face.

"Don't think each one is very simple. The simpler something is, the more it tests your skills."

Fangyuan pointed at the clamping wheel made by Yang Xiaotao, "This thing has very strict data requirements. If there is anything wrong, it will not get stuck in and it will not be able to respond as quickly as possible."

"Do you think that in the event of an emergency, the seat belt will extend half a meter, isn't it the same as nothing?"

"Cheer up, everyone, and don't be careless."

Only then did everyone hide the excitement on their faces, and then returned to their respective posts to start production.

Factory Director Fang and Yang Xiaotao wandered around the workshop, solving problems when they encountered them, and asking questions when they didn't understand something.

"Director Yang, you also designed the pressure cooker in your steel rolling mill?"

"right."

"How about making it for us?"

"Well, Director Fang, let's just say that the simplest kind of friendship pot requires steel and technology, which is not enough in our factory."

"Oh, it's okay, I know. By the way, you have also made a well-drilling machine? We can do this."

"Well, this well-drilling machine uses steam power. If you want to make a steam engine, the steel rolling mill will need the cooperation of more than a dozen seventh-level workers, and the key parts will need eighth-level workers to build it."

Factory Director Fang immediately became uncomfortable after hearing this. He was the only level 8 fitter in their second manufacturing plant. Fortunately, there were still some fitters available, but for things like blacksmiths and welders, level 4 was capped. .

"So, how about the pressure well?"

"This is fine, but are you sure you want to do this?"

"What's wrong?"

"It's nothing, it's just that this water pressure well uses atmospheric pressure. In other words, the manual water pressure well can press up to 10 meters, and here we..."

"Uh~"

Before Yang Xiaotao finished speaking, Director Fang understood what was going on.

The feelings themselves say so much, either the hardware cannot keep up, or the software is not good enough, and in the end even geography is a business trip.

Sure enough, it is difficult to get something.

"Director Yang, look, what can our factory do?"

"Uh~"

Quancheng Automobile Factory.

Liu Dehui held the seat belt sent by the No. 1 Machinery Factory with a serious face.

"try it."

After Liu Dehui finished speaking, the two quality inspectors below stepped forward to pick up the seat belts.

Factory Director Wang on the side also watched nervously.

Previously, their Quancheng No. 1 Machinery Factory made many safety belts based on the samples sent by Yang Xiaotao.

But after delivery, Liu Dehui discovered that these safety belts had serious hidden dangers.

First of all, when the rope used for the belt is pulled out quickly in a collision, it is easy to cause secondary injuries to the driver and even cause bleeding marks.

Later, the No. 1 Machinery Factory reported back to the steel rolling mill and found out that the other party had chosen cloth tape, which was what Yang Xiaotao originally used, so the changes were changed back.

The strap was solved, but there was another problem with the safety device.

In the end, there was no other way. Factory Director Wang personally called and asked for Yang Xiaotao's design data, and asked the workers to strictly follow the data to make a batch this time for experiments.

The two quality inspectors picked up the finished safety belt, then gently applied force and then pulled hard.

Click!

A crisp sound sounded, and the two people quickly took out their rulers to measure.

"Director, 5.5 inches."

"good!"

Liu Dehui responded, and Factory Manager Wang breathed a sigh of relief and said, "Try something else."

"yes!"

Next, all the safety belts were tested. The best 3 cm stuck, and the worst 6 cm could be stuck out. Overall, it was much better than the original one.

"Lao Wang, from now on the quality must be this, it can't be any worse, otherwise I won't be able to explain."

Liu Dehui asked his workers to take the safety belts to install them, and then spoke to Factory Director Wang.

"Don't worry, nothing will go wrong."

"Okay, thank you for your hard work. This time we not only have to give birth, but we also have to change clothes. It takes a lot."

Liu Dehui looked at the busy workshop. Ever since they won the big order from the military, their Quancheng Automobile Factory was like having wings. Every day was the same.

"No, we have a lot of auto repair centers there. They used to install auxiliary systems, but now they also need to install seat belts. This is a business."

"Fortunately, the steel rolling mill told us the data and drawings, otherwise we wouldn't know how long we would be working hard."

Factory Director Wang lamented that their No. 1 machine factory had been praised a lot for its auxiliary system, and so far it had earned more than last year.

"But let me remind you that some things cannot be changed randomly. If you change them, you will get into trouble."

Liu Dehui nodded after hearing this, "Yeah, don't take the porcelain job without that diamond."

"If I had known this, I wouldn't have wasted so much material and energy."

"I can only say that it is indeed designed by Yang Xiaotao, and it cannot be changed."
