Chapter 301 Smart little wife

Sunday morning.

Li Dayong got up early in the morning, rode his bicycle and rushed to the staff dormitory area of ​​Beijing Institute of Technology.

There are still old bungalows here, and the school has a limited number of new staff buildings, which are not enough for all the teachers to move into the buildings.

Li Dayong walked to the door of a bungalow and shouted softly: "Teacher Cao, Teacher Cao?"

"Hey, wait a moment, I'll be right away."

After a while, a male teacher in his thirties came out pushing a 30% new bicycle and rode outside the school with Li Dayong.

After the two pushed the cart out of the dormitory area, Li Dayong asked: "Teacher Cao, did I come early today so as not to disturb your family?"

Teacher Cao said dullly: "No, I woke up long ago."

Li Dayong looked at the beard on Teacher Cao's face that he had not had time to shave, and finally became depressed.

This Cao Zhisheng is the lecturer who teaches Li Dayong's "Mechanical Fundamentals" class. He has a somewhat boring temperament, but he is actually a very nice person. No matter what time or occasion, as long as students ask him questions, he will definitely explain them clearly.

Li Dayong stayed on Hong Kong Island for nearly a month. He dismantled the industrial sewing machines at Fenghua Garment Factory countless times and accumulated many problems.

After returning, Li Dayong asked Cao Zhisheng for advice, but Cao Zhisheng immediately asked him about the specific situation.

Li Dayong didn't dare to say that he went to Hong Kong Island. If the school found out that he got into trouble during a one-on-one game on Hong Kong Island and went to court, it might be very troublesome.

So Li Dayong just said that during his summer vacation, he went to a hometown garment factory to experience life. He saw that imported second-hand sewing machines required foreign exchange, so he became determined to serve the country.

Cao Zhisheng first praised Li Dayong and then explained all the problems to him. However, when Li Dayong asked him "Can we do it ourselves?" Cao Zhisheng was not sure.

Because there is a gap between theory and practice, the finished products produced in the research institute may not be able to be mass-produced, let alone graphics that only exist on drawings?

After talking to Li Ye, Li Dayong proposed the idea of ​​"paid imitation" to Cao Zhisheng, which was actually a copycat.

Cao Zhisheng thought Li Dayong was joking at first. Besides, it wouldn't sound good if he was a lecturer who took students' money.

But when Li Dayong said that once the development was successful, he would be paid at least 3,000 yuan, he was finally tempted.

Cao Zhisheng has two children at home. His wife, who has a rural registered permanent residence, has been sick all year round, and her wife also needs to send money to her family every month. The couple's total salary of more than 100 points is really stretched.

If you can have three thousand, no, as long as you have one thousand yuan, the quality of life at home can be completely renewed.

It’s hard to say about color TVs and refrigerators, but you can always buy electric fans and washing machines, right? I don’t have to carry the laundry all day long with a sore back.

So Cao Zhisheng contacted three classmates and took over the job, and the results soon came to fruition.

But this work is "private work", so Teacher Cao asked Li Dayong to come out early in the morning to avoid being seen by neighbors asking questions.

Not long after Li Dayong left the school, he pointed not far away and said: "Teacher Cao, let's eat first! There is a new mutton soup restaurant over there. I have eaten there and it tastes good.

I can get this reimbursed from my hometown factory. We don’t know how busy we will be today, so we need to eat two more bowls! "

"Can you reimburse me?" Cao Zhisheng nodded and said, "Okay, today is really busy. We have to go to the research institute first, and then go to Nancheng No. 3 Machinery Factory."

The reason why Cao Zhisheng achieved results so quickly was actually due to the fact that two of his classmates happened to work in the same industry chain.

This has to be said about the industrial heritage accumulated by the mainland over the past decades of development.

Li Ye knew a very small case in later generations.

At first, a company had been importing a small elastic component, but because the yield rate was too low, the overseas company was going to stop production. Suitable substitutes could not be found around the world, and they eventually found military units.

Military units do have them, but the yield is only one-tenth, and the purchase price is even more impressive.

Just when the purchasing manager was getting angry, he got news from his classmates that a certain researcher specializes in elastic metals. After some contact, the yield rate was over 90%.

Therefore, although the industrial level of the mainland is very backward, there are countless research institutes, countless machinery factories, and countless skilled workers who have dedicated their lives. No one knows how many talents they hide and how much development potential they have.

And how many people, who have no talent at all, waste half their lives serving tea and water, and finally lie down completely.

After two large bowls of mutton soup, Li Dayong and Cao Zhisheng felt warm all over.

After settling the bill, Cao Zhisheng urged Li Dayong to leave quickly, but Li Dayong said: "Let's wait for someone and then go together."

Cao Zhisheng said in surprise: "Who are you waiting for?"

Li Dayong smiled and said: "People who purchase sewing machines! We have developed a new product and it must be sold to be profitable!"

Cao Zhisheng thought for a while and said: "That's okay, but you have to make an agreement with others first. The product is still in the trial production stage. It is normal if there are any minor problems."

Li Dayong said: "Don't worry, they are also knowledgeable."

After a while, Li Dayong saw Li Yue's Volga.

Pei Wenhui stretched out her head from the passenger seat and said to Li Dayong with a smile: "I saw you from a long way away. You came so early!" Li Dayong smiled and said: "Not too early, not too late, just right. This is Teacher Cao from our school, an expert in light industrial technology."

Pei Wenhui quickly got out of the car, greeted Cao Zhisheng politely, and then asked him to get in the car.

Cao Zhisheng and Li Dayong first spent a dime to store their bicycles before getting into the back seat of the Volga.

However, Cao Zhisheng was very confused. The two girls in front were younger than the other. They didn't look like they were from the purchaser.

The group arrived at the research institute and called Duan Zixiong, a classmate of Cao Zhisheng. Then they went to Nancheng No. 3 Machinery Factory and found Tang Mingtai, a classmate of Cao Zhisheng.

In fact, Li Dayong originally thought of paying the research funds after producing the drawings, but Tang Mingtai served as the deputy director of the workshop at the No. 3 Machinery Factory. Because of the convenience of his position, he produced the results first without spending his own money.

"Hey, Lao Cao, you're already on the Volga, and you're more impressive than our factory director!"

"Don't talk nonsense, the people from the purchasing department are here! Take us to see the products quickly."

"buyer?"

Tang Mingtai was a little surprised because he thought Li Dayong, Li Yue and Pei Wenhui were all students of Cao Zhisheng!

When they arrived at the workshop, several people saw a "bare and hairless" sewing machine.

It has not been painted or polished, and there are even some small parts missing, but the basic structure is considered complete.

Tang Mingtai said: "We have carried out technical research based on the drawings and samples you provided. It is really difficult, but now we have finally reached the standard."

Cao Zhisheng didn't say anything. He went up and inspected it carefully, and nodded after a moment.

But Pei Wenhui took out a set of needlework and fabric from her backpack, and quickly started threading, then moved a stool and started sewing on the spot.

Li Yue came close to Li Dayong and whispered: "Your partner has tender and white hands. He looks like everyone's young lady. How can he still do this?"

Li Dayong said: "She has suffered a lot since childhood. In order to support her brother in college, she dropped out of school for a year to help others sew clothes and earn tuition for her brother!"

Li Yue suddenly understood. Looking at Pei Wenhui, who was thin and small but could turn on the sewing machine very fast, his eyes suddenly changed.

Pei Wenhui used up all the sutures she brought before standing up and saying, "This is not enough. The needle speed is obviously much lower, and the stability is worse than that of the prototype, and the noise is too loud."

Cao Zhisheng, Duan Zixiong and Tang Mingtai were all a little embarrassed. They were either university lecturers, research institute technicians or workshop directors. However, what the three of them jointly researched was criticized by a little girl.

Is this still called "technical compliance"? Are you messing with money?

Tang Mingtai thought about it and said, "Comrade, we have also tested it. This sewing machine is much better than the industrial sewing machines on the market. Is your request too high?"

Pei Wenhui was neither rude nor moved and said: "But the current overseas standard sewing machines have 8000 stitches per minute? You can't even reach 6000 stitches."

"Overseas? Do you want to meet the standards of imported sewing machines?"

Tang Mingtai couldn't help but laugh.

Who doesn’t know how useful imported sewing machines are?

But if a sewing machine wants to produce 8000 stitches per minute, the inertia of the reciprocating movement of the machine head will be very large, and the strength requirements for the reciprocating mechanism are too high, which is not something that can be achieved casually.

Pei Wenhui looked at Li Dayong and felt a little helpless. Although she supported Li Dayong's research, it was too bad. If it was really used in the factory, the sewing workers would be scolded.

Li Dayong sighed and whispered to Pei Wenhui: "I have discussed this issue with my brother. If we can meet the basic requirements, we should try our best to be self-sufficient."

Pei Wenhui nodded, and then said to Cao Zhisheng and others: "I understand everyone's mood, but the minimum standard must reach 6000 needles, and the vibration must be weakened. I will settle the first phase of research expenses for you first."

"I will pay again next time, but if it still fails to meet the requirements, there is nothing we can do. If the workers are not using it smoothly, it will affect the quality of the product. Please understand."

Pei Wenhui opened her small satchel and counted the money from the inside out, but she frowned as she counted.

She looked up at Cao Zhisheng and others, and said sheepishly: "The RMB I brought is not enough. Can I match it with some US dollars?"

"."

Tang Mingtai and others looked at each other and nodded silently.

But when Pei Wenhui counted out eight hundred US dollars at an exchange rate of one to two, the mood of the three people suddenly changed.

"Six thousand revolutions per minute, right? We can do it, just give us some time."

"As long as it is replaced with a micro motor produced in Shanghai, the vibration can be reduced by at least another 20%."

"We can definitely reduce the noise by redesigning the rotating part."

Li Yue pulled Li Dayong and secretly gave him a thumbs up.

"There is probably smoke coming out of your ancestral grave. Otherwise, how could you have met such a shrewd little wife?"

Li Dayong's big bull's eye clicked repeatedly, but in the end he still didn't say a word.

This sister's temper is much more fierce than Li Ye's.
