Chapter 448 Success
After replacing several parts, the hidden dangers of the original grinder were resolved, and the replaced controller did not cause any major problems overall.
Yang Xiaotao walked aside, took off his glasses and put them in his pocket, then nodded to Director Wang and Director Wang, "Director Wang, Director Liu, it should be fine."
Voice After falling, Director Wang immediately nodded to Master Kong who was operating the grinder.
After receiving the instruction, Master Kong immediately turned on the switch and the grinder started rotating rapidly.
Factory Director Wang immediately smiled on his face.
In the past, when the grinder was turned on, there would be a harsh sound, and the noise was constant throughout the working process, and people around it had long been used to it.
But now, the grinder only makes a small sound. It is obvious that these parts are grinding together and are more precise than before.
This move alone showed that the parts Yang Xiaotao replaced were correct.
“Try this.”
Liu Dehui handed a bearing outer ring to Yang Xiaotao and then reported the parameters.
Yang Xiaotao holds the outer ring, and what he is considering now is precision. Knowing that being able to reach this parameter means success.
“Get a few more, I want to test out the standard.”
After hearing this, Director Wang immediately asked someone to bring the outer ring.
After Yang Xiaotao took it, he handed it to Master Kong and asked him to place it on the grinder. Then he turned the control panel and the grinder began to approach the outer ring.
Then with a squeaking sound, a dent was made inside the outer ring.
Master Kong stopped, took out the outer ring and handed it to Liu Dehui for measurement.
“Two millimeters thicker.”
After hearing this, Yang Xiaotao took out a new one, readjusted it, and asked Master Kong to experiment.
“This time it’s about a millimeter thinner.”
Liu Dehui looked excited when he spoke.
Getting closer to the goal little by little, this feeling of being close to success is intoxicating.
Zhizhi
Another one was placed by Master Kong. Yang Xiaotao fine-tuned the turntable, then buckled it, and the machine polished it again.
“Just right, in line with the design requirements.”
Liu Dehui's inner expectation became a reality, and he immediately shouted.
“Great, try again.”
After Yang Xiaotao fixed the scale, Master Kong began to polish the outer ring step by step.
Twenty or thirty were beaten in a row, and Liu Dehui on the side measured each one.
“This is qualified, this is qualified, and this is qualified.”
All of them passed.
Liu Dehui and Director Wang were holding the outer rings and looking at them. Every one of them was a qualified product, and the error was controlled. This speed and efficiency were much better than those polished by an eighth-level fitter. .
This is the power of machines.
After a few people couldn't believe it, they were ecstatic.
Director Wang laughed even more, "Old Liu, are you still worried about not having enough bearings?"
"As much as you want, we will produce them for you, and they will all be high-quality parts. Now you can rest assured."
Yang Dehui nodded silently. This step of change represents a big step forward for the car.
A few people struck while the iron was hot and continued the experiment.
By around two o'clock in the afternoon, the diameter of the outer ring, the diameter of the inner ring, and the degree of polishing were all marked on the disc.
You only need to turn the disc to the specified place to quickly polish and ensure accurate accuracy.
Factory Director Wang saw how quickly a pile of outer and inner rings were piled up, his eyes widening with joy.
In this way, the qualification rate of the bearings has been directly increased to more than 90%, which not only saves a lot of resources, but also improves manufacturing efficiency.
Having such a grinding machine can be as efficient as ten skilled workers.
Even after you become proficient in the operation, the exchange ratio is still higher.
“Comrade Yang Xiaotao, thank you, thank you for your improvement.”
"We will definitely report it to our superiors and ask for credit for you."
Director Wang said, took Yang Xiaotao's hand and shook it vigorously.
With this grinding machine, not only bearings can be produced, but other tasks can also be completed.
And the defective rate of this part will be greatly reduced.
If they hadn't only had one grinding machine, he would have wanted to keep Yang Xiaotao and let him modify everything before leaving.
Similarly, Liu Dehui thought the same thing on the sidelines.
"Engineer Yang, let's go to the automobile factory after dinner."
Liu Dehui sent out the invitation at the right time. Yang Xiaotao was about to agree, but was stopped by Wang Hao on the side.
"Director Liu, I'm sorry, but Mr. Yang will go back to Sijiu City tomorrow. He has to rest in the afternoon, so it's better not to leave the factory."
After hearing this, Liu Dehui frowned and looked at Wang Hao .
It wasn't until he thought of something that his expression relaxed, "It's okay. It doesn't matter if you don't go. Solving the bearing problem will also help us a lot."
After saying that, he looked at Yang Xiaotao and said, "Mr. Yang, come back when you are free. Let’s sit down at the car factory. I’ll go back and tell everyone the good news.”
“You’re welcome.”
Liu Dehui glanced at Director Wang, who nodded to express his understanding. Then he turned around and walked out.
This time I really didn’t even eat anything, so I went back eagerly.
Things in the workshop were over. Factory Director Wang invited Yang Xiaotao to the office. The task was completed, and both of them had relaxed expressions.
"Brother, there is something else I need to trouble you with."
Director Wang poured a vat of hot water himself, and Yang Xiaotao quickly took it, "Brother, if you have anything to say, just say it, no need You're welcome."
"Okay."
Director Wang leaned on the table and took out a red cigarette box with the words "A hand holding a white dove" engraved on it. The word "win" suddenly appeared.
Yang Xiaotao took the cigarette handed over by Director Wang and did not rush to light it. He just smelled it and found that the smell of the cigarette was not strong.
Director Wang took out the matchbox, opened it and handed it to Yang Xiaotao. The two quickly lit it. After a while, bursts of smoke appeared in the office.
"Brother, I want you to leave a copy of the drawings of the grinder to the factory so that if there is a problem in the future, you can repair it."
"Besides, with this Drawings, grinders in other factories can also make targeted improvements.”
“Don’t worry, the credit will be credited to you.”
"What happened to me at that time? It turns out that this is it." Yang Xiaotao exhaled the smoke and didn't feel anything. "I will stay even if I don't tell you."
"As for other factories, if they need you, just feel free to Arrangement, no problem from my side.” I said, this thing is of no use to me. I’ll find a piece of paper later and I’ll draw a copy for you.”
“Okay, bright and happy”
<. br>At the moment, Yang Xiaotao started drawing in the office.
On the other side, Liu Dehui told his workers the good news after returning to the automobile factory, and even gave the bearings he brought back to the workers for testing.
After a while, the test results came out.
The bearing wear is also greatly reduced compared to the previous one, and because the specifications are unified, the car's load capacity is definitely more than the previous 8 tons. As for how much more, actual testing is required.
Liu Dehui asked people to hurry up and test. The observation team will be coming next month, so we must hurry up.
After returning to the office, Liu Dehui regained his composure, thought for a while, and sat at his desk to start drafting what happened.
He said to ask for credit from Yang Xiaotao, so he must do it.
Similarly, after Director Wang left the office, he came to the conference room, where a person was tinkering, also objectively describing what happened this time.
During the afternoon shift, Yang Xiaotao handed the drawings that he had compared twice to Director Wang, and was then dragged towards the canteen by Director Wang.
This time, treat it as a farewell ceremony.
The people eating together were the same people as last night. Of course Liu Dehui didn't come. The specifications were the same as last night, but everyone was in a better mood than last night.
Yang Xiaotao once again became the focus of everyone's drinking. At the end of the day, he was still thinking about his work during the day. Tonight, he just wanted to let go.
"Team leader, this is the train personnel information sent by Section Chief Ding. It includes people who boarded the train in Quancheng and people who boarded the train midway."
Xiaobo will sort it out. Putting down the information, Team Leader Yu nodded, "Follow what I said, find the two duplicates, including From the same factory and unit."
"Chief Ding, your people must always be prepared. If something happens here, you must cooperate fully and try to find out the details before dawn."
< br>"Team Leader Yu, don't worry, I promise there will be no delays."
"Okay."
In the room, a group of people began to register and compare the information, looking at them one by one, never missing any details.
Team Leader Yu lit his cigarette, and the smoke drifted from his oval glasses like a passing cloud.
Section Chief Ding next to him was also smoking, and the scars on his face were looming.
Ten o'clock in the evening.
"Team leader, the results are out."
Xiaobo walked over with the comparison data.
“These three people bought yesterday’s train tickets and tomorrow’s train tickets as well.”
“Zhao He, male, 24 years old. Qihe Wangjiahezi Village Brigade Headquarters Supervisor, the letter of certification is from the brigade headquarters, and I am going to see my relatives in Sijiu City.”
“Liu Feng, male, 34 years old, is a worker at Quancheng No. 4 Machinery Factory. The letter of certification says that he is going to Sijiu City. Study in the city machine repair shop.”
"The last one is Ding Junhong, male, 19 years old. He lives in Dashuihe Village and is a squad leader in the village. The letter of certification was issued by the village brigade. He is going to Sijiucheng to find relatives."
Xiaobo He handed the three pieces of information to Team Leader Yu and took out two pieces of paper at the same time.
"Both of these two people are from Quancheng Flour Mill."
Both of the two papers are women.
"Wang Cuixia, female, 19 years old."
"Li Man, the female is 21 years old."
"Both of them have certificates from flour mills and went to study at Sijiucheng Flour Mill."
Team leader Yu put out the cigarette butts , there are already a lot of cigarette butts piled on the ground.
"Chief Ding, investigate all these people."
"Not only their origins and family members must be investigated, but also the unit that issued the certificate and the reason must be investigated clearly. ”
"Be careful to investigate secretly and don't alert the snake."
"Don't worry, we are all trained and have enough manpower to give you the results before dawn."
"Hard work."
< br>Chief Ding took the materials and ran out, and soon the people in the security department outside got the task. After remembering it, they immediately dispersed and disappeared into the night.
After Team Leader Yu finished his instructions, Xiaobo and others continued to review the materials, while he walked to the phone and reported to the section chief in person.
"Section Chief, there is something that needs to be investigated."
"Yes, the reason why these people came to Sijiu City must be found out. Yes, it must be completed before dawn. Hmm. Okay."
Hang up During the phone call, Team Leader Yu lay on the bed, took off his glasses, squinted his eyes, and went through the situation again in his mind, for fear of missing something.
At three o'clock in the morning, Section Chief Ding walked back quickly.
"Team Leader Yu, the results are out."
Among the three people investigated, "Zhao He and Liu Feng have no problem."
"But when Ding Junhong was investigating, our people found out that Ding Junhong lived a better life than other villagers, and he was a little too lazy to eat. And The person who issued the certificate was their village elder uncle."
"As for the two women. Comrade, the flour mill did send two people, but Wang Cuixia did not get on the train yesterday. The man at home fell ill before leaving, so she gave the place to Li Man. "
"Our people went to the hospital. The man in his family is indeed ill."
Chief Ding said, and Team Leader Yu looked at the investigation data again.
"Ding Junhong is suspicious, so we should pay close attention tomorrow."
"Also, go to the hospital to see what's wrong with this man."
Chief Ding was stunned for a moment, then ran out again.
"Team leader, section chief's phone number."
"Hey, section chief. Tell me."
"Yes, okay."
Soon, the news from Sijiu City was confirmed.
Zhao He’s relatives found the facts and confirmed the facts. The machine repair shop also confirmed Liu Feng’s identity, and the two of them were coming to Sijiu City. Zhao He had made the decision a week in advance, and Liu Feng was eight It was planned months ago.
As for Ding Junhong, according to the information they received, no relatives of his were found in Sijiu City.
In addition, the situation of the flour mill was also confirmed, but it was true that a request from Quancheng Flour Mill was suddenly received four days ago.
The news was put together, and Team Leader Yu read it again and again.
"Xiaobo, follow your comrade to investigate Ding Junhong's village elder uncle."
"Yes."
When Xiaobo heard this, he knew the seriousness and hurried out.
So, another period of waiting.
