Sunday morning.

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

It's still an old bungalow, and the number of new staff buildings at the school is limited enough to allow all the teachers to move in.

Li Dayong walked to the door of a bungalow and shouted in a low voice: "Teacher Cao, Teacher Cao? ”

"Eh, you wait a minute, I'll be fine right away."

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

After the two of them left the dormitory area with the cart, Li Dayong asked, "Teacher Cao, did I come early today and didn't disturb your family?" ”

Teacher Cao said sullenly: "No, I woke up a long time ago." ”

Li Dayong looked at the beard on Mr. Cao's face that he didn't have time to shave, and finally became dull.

This Cao Zhisheng is the lecturer who gave Li Dayong the "Fundamentals of Machinery" class, and his temperament is a little dull, but he is actually very good, no matter what time and occasion, as long as the student asks him questions, he will definitely explain it to the student.

Li Dayong stayed on Hong Kong Island for nearly a month, dismantling the industrial sewing machines there countless times in the Fenghua Garment Factory, and also accumulated a lot of problems.

After coming back, 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, in case he went to the bureau and went to court on Hong Kong Island, it might be very troublesome.

So Li Dayong just said that during his summer vacation, he went to a fellow garment factory to experience life, and saw that imported second-hand sewing machines all need foreign exchange, so he had the heart to serve the country.

Cao Zhisheng first praised Li Dayong, and then explained all the problems to him wholeheartedly, but when Li Dayong asked him, "We can't do it ourselves", Cao Zhisheng couldn't be sure.

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

And Li Dayong, after talking to Li Ye, proposed the idea of "paid imitation" to Cao Zhisheng, which is actually a copycat.

Cao Zhisheng thought at first that Li Dayong was joking, and besides, he was a lecturer who took students' money, which was not good to say.

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

Cao Zhisheng has two children at home, his mother's rural household registration is sick all the year round, and his wife's family also needs to send money on a monthly basis, and the salary of more than 100 points for the two of them is really stretched.

If you can have 3,000, no, as long as you have 1,000 yuan, the quality of life in the family can be renewed.

It's hard to say about color TV refrigerators, but electric fans and washing machines can always be bought, right? The old lady doesn't have to wash clothes all day with back pain.

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

But this work is "private work", so Mr. Cao only asked Li Dayong to come out early in the morning today, so as not to be seen by neighbors and ask questions.

Not long after Li Dayong left the school gate, he pointed not far away and said, "Teacher Cao, let's eat first!" There's a new sheep soup shop over there, and I've been there to eat it, and it tastes good.

I can get reimbursement from my hometown factory, we don't know how busy we will be today, so we have to eat two more bowls! ”

"Can you reimburse?" Cao Zhisheng nodded and said: "That's okay, it's really busy today, we have to go to the research institute first, and then go to the third machinery factory in Nancheng."

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

This has to say that the mainland has accumulated industrial heritage after decades of boring development.

Li Ye knew a very small case in later generations,

At the beginning, a company had been importing a small elastic component, but because the yield rate was too low, the overseas company was about to stop production, and the world could not find a suitable replacement, and finally found a military unit.

The military unit does have it, but the finished product rate is only one-tenth, and the purchase price is even more touching.

Just when the purchasing manager was in a hurry, he got a message from the group of classmates that a research owner specializes in elastic metals, and after some contact, the yield rate is more than 90%.

Therefore, despite the fact that 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, and no one knows how many talents they hide and how much potential for development.

And how many people have no ability, but they have been drinking tea and pouring water for half their lives, and finally lying down completely.

Two large bowls of mutton soup were in their stomachs, and Li Dayong and Cao Zhisheng were warm.

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: "Wait for someone, what are you waiting for?" ”

Li Dayong said with a smile: "The person who purchased the sewing machine! We have researched new products, and we must sell them to be profitable! ”

Cao Zhisheng thought for a while and said, "That's okay, but you have to tell people first, the product is still in the trial production stage, and if there are any small problems, it is normal." ”

Li Dayong said: "Don't worry, they also know how to do it." ”

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

Pei Wenhui stretched out her head from the co-pilot and said to Li Dayong with a smile: "I saw you from a long distance, and I came so early!" ”

Li Dayong smiled and said: "It's not early, it's not too late, it's just right, this is Teacher Cao from our school, an expert in light industry technology." ”

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

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

However, Cao Zhisheng was very puzzled, the two girls in front of him were younger than the other, so they didn't look like people from the purchaser?

When the group arrived at the research institute, they called Cao Zhisheng's classmate Duan Zixiong, and then went to Nancheng No. 3 Machinery Factory and found Cao Zhisheng's classmate Tang Mingtai.

In fact, Li Dayong originally thought that he would pay for the research funds when he came out with the drawings, but Tang Mingtai served as the deputy director of the workshop in the Third Machinery Factory, and because of his convenient position, he did not spend his own money to get the results out first.

"Yo, Lao Cao, you are all sitting on Volga, and you are more energetic than our factory director!"

"Don't talk nonsense, the people from the buyer are here! Hurry up and take us to see the product. ”

"Purchaser?"

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

When they arrived at the workshop, several people saw a sewing machine with a "bare board and no hair".

There was no painting, no polishing, and even some small parts were missing, but the basic structure was completed.

Tang Mingtai introduced: "We have carried out technical research according to the drawings and samples provided by you, and the difficulty is really not small, but now we have finally reached the standard." ”

Cao Zhisheng didn't speak, he went up to check it carefully, and nodded after a while.

But Pei Wenhui took out a set of needles and threads and fabrics from her backpack, and began to thread needles and threads with her hands and feet, and then moved a stool to sew on the spot.

Li Yue approached Li Dayong and said in a low voice: "Your two hands are white and white, and you look like a young lady, how can you do this?" ”

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

Li Yue suddenly realized, looking at Pei Wenhui, who was thin and small, but turned on the sewing machine quickly, her eyes suddenly changed.

Pei Wenhui used up all the stitches she brought in one go, and then stood up and said: "This is not good, the needle speed is obviously much lower, and the stability is worse than 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, technicians at the research institute, and workshop directors, but the things that the three of them worked together to study were sprayed by a little girl and were nothing.

Is this still called "technical compliance"? Fooling the money, right?

Tang Mingtai pondered for a moment and said: "Little comrade, we have also tested it, this sewing machine is much better than the industrial sewing machines on the market. Isn't it too high. ”

Pei Wenhui was polite and unmoved: "But now the overseas standard sewing machine has 8,000 stitches per minute?" You can't even reach these 6,000 stitches."

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

Tang Mingtai couldn't help but laugh.

Who doesn't know that imported sewing machines are so good!

However, if the sewing machine wants 8000 stitches a minute, the inertia of the reciprocating motion of the machine head will be very large, and the strength of the reciprocating motion mechanism is too high, which is not something that can be done casually.

Pei Wenhui looked at Li Dayong, and was also a little helpless, although she supported Li Dayong's research very much, but too bad is too bad, if it is really used in the factory, the sewing worker will scold her mother.

Li Dayong sighed and whispered to Pei Wenhui: "I discussed this issue with my brother, if you can meet the basic requirements, you should try to be self-sufficient." ”

Pei Wenhui nodded, and then said to Cao Zhisheng and the others: "I understand everyone's feelings, but the minimum standard must also reach 6,000 needles, and the vibration should be weakened a little more, and I will settle the first phase of research fees for everyone first."

"Next time I will pay again, but if it still does not meet the requirements, then there is no way, if the workers do not use it well, it will affect the quality of the product, please understand."

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

She looked up at Cao Zhisheng and the others, and said embarrassedly: "The RMB I brought is not enough, can I match some US dollars?" ”

“.”

Tang Mingtai and the others glanced at each other and nodded silently.

But when Pei Wenhui pointed out 800 US dollars at the exchange rate of one to two, the mood of the three of them was suddenly different.

"6,000 revolutions per minute, right? We can do it, give us a little time. ”

"As long as you replace a miniature motor made in Shanghai, the vibration can be reduced by at least another 20 percent."

"We've redesigned the rotating part to keep the noise down."

Li Yue pulled Li Dayong and secretly extended a thumbs up.

"Your ancestral grave is probably smoking, otherwise how could you meet such a shrewd little daughter-in-law?"

Li Dayong's bull's eye clicked many times in a row, and a word was still not said in the end.

This sister's temper is much fiercer than Li Ye's.
