Chapter 1602 Three-roll rolling mill
Machinery factory, second workshop.
When Yang Xiaotao walked in, there was a rumble around him.
Every worker is busy, and they cannot be distracted by the work at hand, otherwise a component will be destroyed.
Here, every worker has his own position and is responsible for the parts he produces.
Now the second branch factory already has a mature processing system.
Ordinary semi-automatic milling machines, lathes, etc. can already be produced on a large scale. After the products are processed, the pass rate has exceeded 80%.
At the same time, this is also the main product produced by the second workshop.
As for the somewhat difficult machine tools like Daystar and Shining Daystar, the success rate is about 60%, and there are not many people in charge of production, but they are all veteran workers with level 6 or above.
Of course, the machinery factory is also thinking about adjusting the ratio of personnel and increasing the production quantity of machine tools like Venus.
But in the end, it was discovered from the tasks received that compared with good machine tools like Venus, the domestic demand was actually an order of magnitude lower than ordinary machine tools.
Finally, after getting to know Yang Youning and others, they found out that some of the factories that accepted Daystar were doing ordinary machine tool work.
It is better to use ordinary machine tools, the processing is simple, the operation is simple, and it saves money.
As for considering accuracy, the accuracy requirements given in the task are not high anyway, and ordinary machine tools can also meet them, so why bother with better ones?
In this regard, the leadership of the machinery factory could only criticize it privately as "not wanting to make progress" and "holding back the revolution."
But I really don’t dare to say it face to face.
Because there are too many people on the other side, so we can’t offend the public.
Because of this, the main task undertaken by the machinery factory is still the production of ordinary semi-automatic machine tools.
At this point, Yang Xiaotao and the others were speechless.
I can’t give away good things.
Simply helpless.
Ordinary machine tools have heavy tasks, but that does not mean that other machine tools have light tasks.
On the contrary, the production tasks of Morningstar Machine Tools are equally urgent.
Even in some cases, very eager.
It’s just that the difficulties in Chenxing machine tool production have shown that without a key breakthrough in technology in the near future, it is just a dream to achieve large-scale production.
The machinery factory is also thinking of handing over the production tasks of ordinary machine tools to a branch factory or other factories.
But in today's situation, the production capacity of the first branch factory is a problem, and they also have to bear the task of producing tractors.
As for the First Machinery Department, it's not that they don't cooperate with adjustments. It's just that they can't find a suitable factory.
The First Machinery Department conducted an investigation before, and the result was that they really couldn’t find a factory to take over.
Not to mention ordinary machine tools, even semi-automatic series machine tools. If you go with the drawings, the machine tool manufacturers below will be blinded.
A capable machine tool factory like Jinling is feasible, but in the face of Venus, there are really not many domestic manufacturers that can produce it.
But facing the shining star, the claws are numb.
Without the help of advanced machine tools like Morning Star, Shining Morning Star would be like a mirror image.
Even though the Morningstar machine tools produced by the machinery factory were given to many departments, the situation has not changed.
For example, our boss has at least three machines in his machine department.
If it is handed over to a machine tool factory, it is possible to produce a Venus, and maybe an upgraded version of the Shining Venus can also be produced.
But in fact, these three Morning Stars from the First Machinery Department are all used in other fields.
It’s not that machine tool production is unimportant, but there are more important areas.
Just like the Seventh Machinery Department, the morning stars given to them are used to produce precision parts for rockets.
Where can I find the time to research machine tools?
Moreover, machine tools are subject to wear and tear during use, and they also have a service life under normal circumstances.
Like tool wear, this is no small burden.
Don’t do porcelain work without diamonds.
If you don’t have hard enough materials, just dream about cutting hard equipment.
There is also mechanical wear and tear, which cannot be avoided.
Just like the joints of the human body, they will wear out over time.
For these, if you want to improve, you have to use better materials and more comprehensive maintenance.
But domestic materials are just like that. If you want to develop, you must get the raw materials.
For all this, it is more cost-effective than letting the machinery factory provide it directly.
Anyway, if the machine tool in the machinery factory is worn out, you can repair and replace it yourself.
They can just use it directly, why bother themselves?
As a result, the machine tools provided by the machinery factory became a hot commodity.
This is why Mr. Wang from the Seventh Machinery Department always caught Yang Xiaotao and asked for the machine tool.
The main focus is a benefit.
“Mr. Yang!”
Chang Mingjie saw Yang Xiaotao coming and stood up to greet him.
Yesterday’s art performance, Yang Xiaotao gave him a chance to shine.
There were so many people in the audience, apart from the actors, they were the only ones who talked to the chief and had close contact with him.
When he said "Go home", the elders in the family were very excited. Even the children shouted happily, and his wife looked at him with admiration.
Of course, he knew that Yang Xiaotao brought all this.
Without his initial support, he would not have been the director.
Without his innovative development, the machinery factory would not be where it is today.
So he admired Yang Xiaotao very much.
Not far away, Zhang Guanyu, Chen Bin and others hurriedly stepped forward when they saw Yang Xiaotao coming.
“Mr. Yang, Mr. Yang!”
Several people came up to say hello, Yang Xiaotao nodded, and then saw Liu Daming sitting aside guarding the machine tool, "Mr. Yang, you came just in time, come and take a look."
As he said hello, aside Chang Mingjie also showed an embarrassed smile, "Isn't this an improvement of the rolling mill? I encountered some trouble."
Yang Xiaotao was not surprised when he heard this. After all, according to the drawings they gave, there would be no problems. Strange.
"It just so happens that I came to you for this matter too!"
After speaking, Yang Xiaotao walked aside and inspected the steel rolling mill assembled next to Liu Daming.
Yang Xiaotao originally handed over his drawings of dismantling the rolling mill to the R&D department, so the design style was biased towards the alliance.
After all, the rolling mills that were dismantled were all owned by the alliance, so it is not surprising that they were affected.
But most of the products of the alliance have one thing in common, that is, they are rough and tough. Of course, it may be an advantage in other aspects, but in this delicate work, it is a problem.
So it is normal that the design drawing given by the R&D Department has these problems.
After looking at the new rolling mill for a while, Yang Xiaotao said nothing, but Chang Mingjie on the side spoke.
"Mr. Yang, although this steel rolling mill has been built, the accuracy requirements are still low."
"Especially the third roller controlled by this, it cannot meet the requirements at all."
"We are trying to think of ways to improve it, but we have no clue at the moment!"
Liu Daming heard this and flexed his muscles, "No, there is obviously nothing wrong with it. It's just that the accuracy can't be achieved. What should we do?" ”
Yang Xiaotao didn't speak. He just came to the side and started the machine. A clicking sound was heard. After running for a while, Yang Xiaotao turned off the power.
In general, it was the same as his judgment after seeing the drawings.
So he walked aside, took out the original drawings and spread them on the machine.
A few people around looked at each other, and then stared with wide eyes.
Every time Yang Xiaotao took out the design drawings, it showed that the problems they were troubled by were not problems.
"I looked at the drawings given by the R&D Department and tried to make the machine. Generally speaking, it meets the original design requirements and there is no problem in grasping the direction."
When Yang Xiaotao saw everyone gathered over, he immediately started explain.
“But here, I think it should be the biggest problem.”
At this point, Yang Xiaotao pointed to the power system, and everyone looked over again.
Chang Mingjie and Chen Bin are both engineers. They were already aware of the problem when Yang Xiaotao pointed it out, and Liu Daming and the others were also aware of the problem.
"I have calculated that based on past data, if we design and manufacture according to this, the power will not meet our needs, and if we use it forcibly, it is likely to cause mechanical failure!"
"I also tried it just now. , this power system is similar to the previous steel rolling mill, but with one more roller, the effect is Big discount."
After Yang Xiaotao finished speaking, everyone nodded, and Pang Guo on the side asked, "We produced two in the early stage, but the results were not good."
"Look now. Come on, there is really a problem with the power."
Liu Daming also nodded.
"Actually, the power is not strong enough and the speed is not fast enough. This slowdown and instability will naturally affect the accuracy of the work."
After speaking, Liu Daming looked at Yang Xiaotao again, "Mr. Yang, Now that you have discovered the problem, how do you solve it?"
After Liu Daming finished speaking, everyone immediately looked at Yang Xiaotao.
Yang Xiaotao did not disappoint. He pulled out a piece of paper from the bottom of the design drawing, which showed his revised design drawing.
Everyone looked again and saw that changes had indeed been made to the power system.
Moreover, this change also expanded the rolling mill a lot.
This is the result of Yang Xiaotao's modification based on the original design.
Although the system did not give an evaluation, in Yang Xiaotao's view, this simple design is feasible.
“Actually, there is no problem with this design, but we just didn’t consider it comprehensively.”
“My opinion is that the material of this movable roller should be heavier and harder.”< br>
"At the same time, comrades who increase the power output and increase the counterweight..."
With Yang Xiaotao's explanation, everyone understood the difference.
"Understood?"
After Yang Xiaotao finished speaking, no one responded, so he hurriedly asked.
Chang Mingjie reacted quickly and nodded hurriedly.
"Understood!"
Liu Daming clapped his hands, "If I had known earlier, I would have waited until you came back to do it. This is a waste of emotions and materials."
While speaking, Hou Baowei poked at him. Lowering his waist, Liu Daming looked back, only to find Hou Baoyuan looking at Zhang Guanyu next to him. After hearing this, the latter's face froze and he looked a little depressed.
Everyone knows that Director Zhang of the R&D Department is an honest boy. He doesn't talk much, but he does things in a orderly and serious manner.
The attitude is very positive.
In the early years, because the work was slow, Yang Youning said, "The stupid bird flies first. If the work is slow, then come early."
After that, when others arrived at work at eight o'clock, he came at seven o'clock.
And for so many years, except for business trips, I always come in early and leave late.
This attitude, in the eyes of everyone, is more popular than personal ability.
“Ahem, I feel like I wouldn’t be where I am now without the previous accumulation.”
Liu Daming hurriedly changed his words, and Hou Baobao nodded, "Yes, yes, what Lao Liu said is right, we almost succeeded, it's only a matter of time, sooner or later."
After saying that, he picked up the drawings. He walked aside to prepare to modify the power equipment and strive to complete the production of the rolling mill as soon as possible.
Chang Mingjie nodded after hearing this. Zhang Guanyu saw everyone's expressions and felt very grateful.
“That’s well said.”
“As designers, we never succeed the first time. Failure is the norm.”
Yang Xiaotao walked up to Zhang Guanyu and said, "Director Zhang."
"Mr. Yang!"
"I still have a task."
Hearing Yang Xiaotao say this Said, Zhang Guanyu nodded in agreement.
“Mr. Yang, tell me!”
"Well, this three-high rolling mill is ready, but it is not the end."
"Foreign six-high rolling mills have been built. How big the gap is. It is not a simple matter of one, two, and three." It can be summarized.”
After speaking, Yang Xiaotao looked at Zhang Guanyu seriously, “So I’ll give you the task. That is to make a four-roller rolling mill, or a higher six-roller rolling mill..."
"In the future, our domestic steel rolling mills can also use our own rolling mills."
" This is of great significance to national development and revolutionary construction, so you must work hard!”
Zhang Guanyu looked excited. The fact that Mr. Yang entrusted them with such an important task showed his trust and respect.
“Don’t worry, Mr. Yang, our R&D comrades will go all out to complete the assigned tasks.”
Zhang Guanyu shouted loudly, and Liu Daming and others who were busy beside him opened their mouths, They are also members of the research and development team, but they are not sensitive to what Yang Xiaotao said.
Of course, this is also related to their status. They are only responsible for doing it. As for how to do it, they still have to listen to the designers.
But it’s really an honor for them to finish it.
"Don't be stressed. Once this three-roll rolling mill is built, let the steel plant use it first. We will do it step by step."
Zhang Guanyu nodded vigorously.
