Chapter 973 Improving the Milling Machine
In the room, Ran's mother, Ran Qiuye and others have been waiting for a long time. Ran Hongbing even called into the study twice, but the answer he got was, you eat first.
"What are these two men busy with? They are in the house right after they come back, and they haven't even eaten!"
"Who knows, they look worried when they come back, it must be because of their work. "
Ran Qiuye listened at the door for a while and vaguely heard something about the machine tool, but he didn't understand it.
However, the expressions of father and Yang Xiaotao were very serious, it must be a very important matter.
"That can't delay the meal! Go and call!"
Ran's mother said, and Ran Qiuye responded.
It wasn't until Ran Qiuye went in for a while that the two of them walked out of the study and started eating.
Only at the dinner table, everyone could clearly feel that the two of them were absent-minded. They both ate quickly, and they used to say a few words, but this time it was purely for the sake of eating.
Even Ran Qiuye didn't drink the wine he prepared. He ate it hastily and went back to the study.
Ran's mother and Ran Qiuye couldn't understand, so the old Taoist smiled and explained.
“The two of us are the same kind of people, and we met because of our interests.”
After hearing this, the two smiled helplessly.
In the past, having a "bookworm" like Ran's father in the family, Ran's mother already had a headache. She was not diligent in all aspects of her body and could not distinguish between grains and grains. She didn't expect to find a brother-in-law who was like this. The two fathers were actually "like each other".
But this is good, it shows that the two of them get along well.
Of course, in Ran Qiuye's heart, these two people have always been like this, which is the best.
In the study.
The desk has been emptied. Yang Xiaotao spread out the drawings for the milling machine. The entire table was covered with drawings.
Although Ran’s father studied physics, he was also responsible for the design of the casing when he was in Northwest China. Although he didn’t know much about instrument design, the basics were there. More importantly, he could understand German. Things in the book can be interpreted.
So, while looking at the drawings of the milling machine on the table, I read it against the book and provided opinions from time to time.
"Here, if semi-automation is used, manual operation methods need to be changed. This kind of operation control is not good."
Ran's father pointed at a drawing and said, Yang Xiaotao looked at it and stretched out his hand to pinch it He lowered his chin, thinking in his mind, and then shook his head, "It's really not possible here. But manual operation is not just a matter of pressing a button, it also requires adjusting the position of the milling cutter, and the heating problem during the processing must also be considered, so it is not appropriate to simply change this."
Yang Xiaotao rejected Ran. Ran's father didn't care about his father's suggestion. He felt that Yang Xiaotao was right.
“So, here, here and here.”
Yang Xiaotao clicked on the drawing with a pencil, "Everything needs to be changed!"
Ran's father nodded. A single move can affect the whole body, especially for precision machine tools.
“Of these three places, this is the easiest!”
Yang Xiaotao started from the problem points pointed out by Ran’s father, spread out in three directions, and then conquered each direction. This kind of simplicity and clarity Ran's father agrees with this idea.
Of course, there is also a risk in doing so, that is, the final change will not be able to respond to other parts, thus requiring a wider range of changes.
However, at the initial stage, it is impossible to judge whether this kind of change is correct or not.
Even after it is done, actual construction is required to ensure the design is correct.
This process is particularly long.
This is why domestic research on advanced machine tools has been stagnant.
Time, energy, materials, and fear of failure.
Ran's father knew all this because they had experienced this kind of thing during those years in the northwest.
It was just the serious look of veteran Yang Xiaotao that reminded him of his past self. At that time, he was still young and frivolous, and also full of passion.
That person is not young.
The dream of youth is still a dream!
“When I was in Quancheng, I made a precision disc for their grinder.”
Suddenly, Yang Xiaotao slapped his forehead and stood up excitedly.
Ran's father was interrupted from thinking by Yang Xiaotao, and then he saw Yang Xiaotao mumbling.
"Precision disk?"
"Yes, that's right."
As Yang Xiaotao said, he pulled out a notebook from the drawer, rummaged through it, and handed it to Ran My father looked at it and explained, "Last time I went to Quancheng Machine Tool Factory to help..."
"Then we will improve it and deal with this!"
"In fact, it is a gear matched with a precision disk to achieve manual controllability."
As Yang Xiaotao told, Ran Father's eyes stared at the drawings in the notebook, getting brighter and brighter.
“This is a good idea. We can install this on grinders in the future, which will greatly improve efficiency!”
Yang Xiaotao nodded, “Dad, look at this thing, it’s actually a controller. It’s the same as the machine tool. The gearbox is similar, I think it can be designed into it!”
Ran's father did not answer in a hurry, but thought carefully and carefully.
Yang Xiaotao was not in a hurry, just explaining his plan from the side, and Ran's father also asked about the design requirements from time to time.
The two discussed for a while, and half an hour later, Ran's father nodded, "It seems that we can also build one for the milling machine."
"This can control the relationship between the milling cutter and The distance between the parts allows for milling. ”
“Besides, the operation does not require too much pressure”
Yang Xiaotao nodded and continued the discussion.
Ran's father and Yang Xiaotao had been discussing in the study until midnight. Seeing this, Ran Qiuye did not go back with his family. Since there were many rooms at home, he arranged for his family to rest.
Yang Xiaotao was lying on the bed, hugging his wife from behind. He felt a fullness in his hands, but his mind was filled with drawings, structures, and shapes.
When I woke up the next morning, Ran's father didn't sleep well either.
The two of them felt like they were chasing a book. They wanted to read it in one sitting, but they didn’t have so much time and energy. They could only think about it and remember it.
After breakfast, Ran's father wanted to go to the library to see if there was any information in this field. Yang Xiaotao took the drawings to the steel rolling mill to continue the design.
Seeing the two people's appearance, Ran Qiuye asked Ran's mother to stay at home.
We are all a family anyway and don’t need to see anyone outside. Moreover, she also knew that her father's time at home was running out.
Ran’s mother didn’t refuse. Here, she could help take care of the children, and she felt comfortable.
In the courtyard, everyone knows the situation of the Yang family, Ran's mother also knows him, and he has also gotten to know Ran's father in the past two days. People in the courtyard are very polite.
This place is similar to the courtyard.
In the Jia family, Qin Huairu cooked a meal and let the three children eat. He gave Xiaodang and Sophora japonica to the eldest mother to help look after them, and then went out with a basket and stick stalks.
The basket contains some patched fabrics, which are the masterpieces of the past few days.
In the compound, no one helped her family, and even when she was walking around, Qin Huairu had to let go of her unnecessary thoughts and start running for a living.
Two days ago, I went to the subdistrict office to explain the situation. Considering Qin Huairu's situation and having a sewing machine, the subdistrict office assigned some fabric sewing work, which cost a few cents in one day.
Qin Huairu had no choice, it was better than sweeping the floor on the street.
Although it would save a meal, this kind of work made her feel more decent.
As for Banggen, he was sent to school by Qin Huairu.
My legs and feet have almost healed during this period, so it’s okay to stay at home.
In addition, all the children in the courtyard went to school, so it was not a problem for Bangge to stay at home.
Of course, Qin Huairu's heart is more about letting Banggeng study hard.
I heard a few days ago that the children in Yangjiazhuang were admitted to junior high school. Not only were they given a lot of things, but they also received scholarships. That’s three or four yuan a month. You can earn it at such a young age without even working. Money made her jealous.
Furthermore, sending her children to school is also a solution she has long thought of. Only going to school can change the current predicament.
In this regard, Yang Xiaotao is a role model for the whole hospital.
After taking Bangeng out of the house, as soon as he walked out of the alley, the sound of a bicycle came from behind. Qin Huairu pulled the reluctant Bangeng to the side, and then saw Yang Xiaotao passing by on a bicycle.
"Banggeng, learn to read well. When you grow up, your mother will be yours!"
Banggeng shrugged his head. He had a headache when he heard about going to school, but he didn't have to do this. I could only shrug and nod.
"Good son, study hard. Once you study well, you can find a good job. Once you have a job, you can find a wife in the city and live a good life. Your mother will take care of your children when the time comes. You guys work hard. Make money..."
Qin Huairu walked with Bangge, looking forward to the bright future.
Although placing all hope on future generations is an evasive attitude and an extremely irresponsible behavior.
But for Qin Huairu, this may be her only thought at the moment.
Banggeng nodded silently. As for the future, he is still waiting for his eldest brother to come out and do something big.
……
After Yang Xiaotao rode to the steel rolling mill, he first went to the workshop to have a look.
One of the two machine tools makes a punch press, and the other makes a milling machine, with almost no downtime.
When we came to the workshop, Chen Bin was leading people to work, and the second milling machine was about to be finished.
In addition, the order for punch machines is not small, and the factory also needs to purchase pressure cookers for the production of pressure cookers. Now that the production tasks are increasing, more punch machines are needed.
After watching for a while, Yang Xiaotao went to the tractor workshop to check on the progress. The person operating the milling machine was Zhou Hong, who was specially seconded from the R&D Department in order to increase the success rate.
Yang Xiaotao watched for a while and realized that Zhou Hong's skills were indeed better than those of yesterday's workers, but they were not 100% accurate, and with the consumption of physical strength and energy, this accuracy rate could not be guaranteed.
Then Yang Xiaotao returned to the office, spread out the drawings, and continued to study.
In the office, Lou Xiaoe is sorting out information. She has not been to the Yang family in the past two days, mainly because there are many people in the Yang family, and it would cause trouble for her to go.
Besides, there has been a lot going on in the factory recently.
The production of machine tools is said to have sent requests from factories throughout Sijiu City, hoping that the rolling mill will support a machine tool.
This is just a punch machine. Now that milling machines have been made, it is estimated that there will be another wave.
The successful development of diesel engines and the smooth production of tractors made the steel rolling mill even more prominent.
This makes them very proud to be members of the steel rolling mill.
"Director, this is the detailed situation in August, the output and income of tractors."
"This is the task situation of machine tools..."
Lou Xiao'e will A completed report was placed in front of Yang Xiaotao. Yang Xiaotao took it and only glanced at it twice, then signed to express understanding, and continued to look at the drawings.
When Lou Xiao'e saw this, she didn't bother him. The whole factory has been busy recently, and Yang Xiaotao has long been used to this situation.
Just as Lou Xiaoe walked aside, Yang Youning suddenly walked in at the door.
Looking at Lou Xiaoe, Yang Youning walked up to Yang Xiaotao.
Seeing Yang Xiaotao pondering over the drawings again, he endured his worries and stepped forward to check.
“Is this a milling machine?”
After looking at the drawings, Yang Youning thought it looked familiar and asked.
When Yang Xiaotao saw Yang Youning coming, he just raised his head and said hello. At this moment, his head was full of drawings and designs, so he just nodded when he heard this.
“Yes, Hong Mian No. 1!”
“I plan to improve it and see if I can make Hong Mian No. 2!”
In view of Yang Youning’s naming Way, Yang Xiaotao replied without raising his head.
Seeing this, Yang Youning became even more confused. If the milling machine has not been built yet, what else is there to study?
Hong Mian No. 2?
The order for Hong Mian No. 1 has just come down. They haven’t even started the delivery yet. Are they planning to work on Hong Mian No. 2?
This update is a bit fast.
At least let Hong Mian No. 1 shine. If there is No. 2, who needs No. 1?
Will those manufacturers who have received Hongmi No. 1 come to return the product if they learn that there is a better one?
Yang Youning's head was spinning very fast, and he quickly thought of several possibilities, and then thought about countermeasures in advance for each possibility.
Is there any reason to exchange the things that have been sold?
Why is it written on the wall of the supply and marketing cooperative, ‘No returns or exchanges will be made when leaving home. ’
