Chapter 1602 Three-Roller Rolling Mill

Machinery factory, workshop 2.

When Yang Xiaotao walked in, there was a rumble around.

One worker after another was busy, and the work at hand made them unable to be distracted, otherwise a part would be destroyed.

In this, every worker has his own position and is responsible for the parts he produces.

Now the second branch has a mature processing system.

Ordinary semi-automatic milling machines, lathes, etc. can already be mass-produced, and the qualified rate of products after processing has exceeded 80%.

At the same time, this is also the main product produced by the second workshop.

The success rate of machine tools with a little difficulty, such as Venus and Shining Venus, is about 60%, and there are not many people in charge of production, but they are all old workers above level 6.

Of course, the machinery factory also wants to adjust the staff ratio and increase the production of machine tools such as Venus.

But in the end, it was found from the tasks received that compared with good machine tools like Venus, the domestic demand was actually an order of magnitude lower than that of ordinary machine tools.

Finally, Yang Youning and his friends learned that some factories that received Venus did the work of ordinary machine tools.

It is better to use ordinary machine tools, which are simple to process and operate, and save money.

As for considering accuracy, the accuracy requirements given in the task are not high anyway, and ordinary machine tools can meet them. Why do we have to have better ones?

In this regard, the leadership of the machinery factory can only criticize them privately as "not making progress" and "holding back the revolution".

But if they really say it to each other's face, they really dare not.

Because the other party has too many people, they can't offend the public.

Because of this, the main task of the machinery factory is still the production of ordinary semi-automatic machine tools.

Yang Xiaotao and others are speechless about this.

Good things can't be delivered.

It's just helpless.

Ordinary machine tools have big tasks, but it doesn't mean that other machine tools have light tasks.

On the contrary, the production tasks of Morning Star Machine Tools are equally urgent.

Even in some uses, it is very urgent.

It's just that the difficulties in the production of Morning Star Machine Tools have shown that in the absence of key breakthroughs in technology in the near future, it is a dream to want to produce on a large scale.

The machinery factory also wanted to hand over the production of ordinary machine tools to the first branch or other factories.

But in the current situation, the production capacity of the first branch is a problem, and they also have to take on the production of tractors.

As for the First Ministry of Machinery, it is not that they do not cooperate with the adjustment, but they really cannot find a suitable factory.

The First Ministry of Machinery conducted an investigation before, but it really could not find a factory to take over.

Not to mention ordinary machine tools, even semi-automatic series machine tools, the machine tool factories below will be at a loss when they take the drawings.

Capable machine tool factories, such as Jinling, are feasible, but facing the Morning Star, there are really not many domestic ones that can produce it now.

But facing the Shining Morning Star, they are directly at a loss.

Without the help of advanced machine tools such as Morning Star, Shining Morning Star is just a mirage.

Even if the Morning Star machine tools made by the machinery factory are given to many departments, this situation has not changed.

Like its own boss, the First Ministry of Machinery, there are at least three.

If it is handed over to the machine tool factory, it can completely produce the Morning Star, and maybe the upgraded version of Shining Morning Star can also be made.

But in fact, the three Morning Stars of the First Ministry of Machine Building were used in other fields.

It’s not that machine tool production is not important, but there are more important fields.

Just like the Seventh Ministry of Machine Building, the Morning Stars given to them were used to produce precision parts for rockets.

Where is the time to study machine tools?

Moreover, machine tools are worn out during use, and they also have a service life under normal circumstances.

Just like tool wear, this is a big burden.

Don’t take on porcelain work without diamond drills.

If you don’t have hard enough materials, it’s a dream to think about cutting hard equipment.

There is also mechanical wear, which cannot be avoided.

Just like the joints of the human body, they will always wear out after a long time of use.

For these, if you want to improve, you have to use better materials and more comprehensive maintenance.

But the domestic materials are like that. If you want to develop, you must get the raw materials.

And all this is better than letting the machinery factory provide it directly.

Anyway, the machine tools at the machinery factory can be repaired and replaced by themselves if they are worn out.

They can just use it directly, why bother themselves?

Therefore, the machine tools provided by the machinery factory became a hot commodity.

This is also the reason why Mr. Wang of the Seventh Machine Department always asked for machine tools whenever he saw Yang Xiaotao.

The main point is a good deal.

"Mr. Yang!"

Chang Mingjie saw Yang Xiaotao coming and hurriedly 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, and except for the actors, they were the only ones who could talk to the leader and had close contact with him.

When he said "Let's go home", the elderly at home were very excited, even the children shouted happily, and his wife looked at him with admiration.

Of course, he knew that all this was brought by Yang Xiaotao.

Without his support, he would not have been the director.

Without his innovation and development, the machinery factory would not have been where it is today.

So he admired Yang Xiaotao very much.

Not far away, Zhang Guanyu, Chen Bin and others saw Yang Xiaotao coming and hurried forward.

"Mr. Yang, Mr. Yang!"

Several people came up to greet him, 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."

While greeting him, Chang Mingjie on the side also showed an awkward smile, "This is not to improve the rolling mill, and there are some troubles."

Yang Xiaotao was not surprised to hear this, after all, according to the drawings they gave, it would be strange if there were no problems.

"It just so happens that I came to you for this matter!"

After saying this, Yang Xiaotao walked aside and checked the assembled rolling mill next to Liu Daming.

At the beginning, Yang Xiaotao handed over the drawings of his dismantling the rolling mill to the R&D department, so the design style tended to be alliance-oriented.

After all, the rolling mills that were dismantled were all from the Alliance, so it was not surprising that they were affected.

But most of the Alliance's products have one thing in common, that is, they are rough and tough.

Of course, this may be an advantage in other aspects, but it is a problem in this delicate work.

So it is normal that the design drawing provided by the R&D Department has these problems.

After looking at the new rolling mill for a while, Yang Xiaotao did not speak, but Chang Mingjie on the side spoke.

"Mr. Yang, although this rolling mill has been made, the accuracy requirements are still a little short."

"Especially the third roller of this control, which does not meet the requirements at all."

"We are trying to improve it, but we have no idea for the time being!"

Liu Daming listened and flexed his wrist, "That's right, there is obviously no problem. It's just that the accuracy is not up to standard. What should I do?"

Yang Xiaotao did not speak, but came to the side to start the machine, and 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 drawing.

So he walked to the side and took out the original drawing and spread it on the machine.

The 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. Overall, it meets the original design requirements, and there is no problem with the direction."

Seeing everyone gathered, Yang Xiaotao began to 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 were engineers. When Yang Xiaotao pointed it out, they had already realized where the problem was, and Liu Daming and others also realized where the problem was.

"I calculated that according to previous data, if we design and manufacture it according to this, the power will not meet our needs, and if we force it to be used, it is likely to cause mechanical failure!"

"I tried it just now. This power system is similar to the previous rolling mill, but with an extra roller, the effect is greatly reduced."

After Yang Xiaotao finished speaking, everyone nodded, and Pang Guo on the side asked, "We made two in the early stage, but the effect was not good."

"Now it seems that there is really a problem with the power."

Liu Daming also nodded.

"In fact, it is not strong enough and the speed is not fast enough. This slowdown, coupled with instability, naturally affects the precision of the product."

After speaking, Liu Daming looked at Yang Xiaotao again, "Mr. Yang, since you have found the problem, how do you solve it?"

After Liu Daming finished speaking, everyone immediately looked at Yang Xiaotao.

Yang Xiaotao did not disappoint people. He pulled out a piece of paper from the bottom of the design drawing, which showed his modified design drawing.

Everyone looked again and found that the power system had indeed been modified.

And this modification also expanded the rolling mill a lot.

This is the result after Yang Xiaotao modified the original design.

Although the system did not give an evaluation, in Yang Xiaotao's opinion, this simple design is feasible.

"In fact, there is no problem with everyone's design, but it is not considered comprehensively."

"My opinion is that the material of this movable roller should be heavier and harder."

"At the same time, the comrade who increases the power output should increase the counterweight..."

As Yang Xiaotao explained, everyone understood the difference.

"Understand?"

After Yang Xiaotao finished speaking, he saw that no one responded, so he hurriedly asked.

Chang Mingjie responded quickly and nodded.

"Understand!"

Liu Daming clapped his hands, "I should have waited for you to come back before doing it. This is a waste of emotion and materials."

While speaking, Hou Baowei poked his waist. Liu Daming looked back and found that Hou Baowei looked at Zhang Guanyu next to him. The latter's face froze and his expression was a little depressed.

Everyone knows that Director Zhang of the R&D Department is an honest child. He doesn't talk much, but he does things in an orderly and serious manner.

Very positive attitude.

In the early years, because he worked slowly, Yang Youning said, "The early bird catches the worm." If you work slowly, come earlier.

As a result, since then, when others arrive at work at 8 o'clock, he comes at 7 o'clock.

And for so many years, except for business trips, he always comes early and leaves late.

In the eyes of everyone, this attitude is more likable than personal ability.

"Ahem, I think without the previous accumulation, I can't do this now."

Liu Daming hurriedly changed his words and said, Hou Baowei also nodded, "Yes, Lao Liu is right, we are almost successful, it's not a matter of time."

After speaking, he picked up the drawings and walked aside to prepare to modify the power equipment, striving to complete the production of the rolling mill as soon as possible.

Chang Mingjie nodded after listening, and Zhang Guanyu saw the expressions of everyone and was still very grateful in his heart.

"Well said."

"We designers, how can we succeed in one go? Failure is the norm."

Yang Xiaotao said as he walked to Zhang Guanyu, "Director Zhang."

"Boss Yang!"

"I have another task."

Hearing what Yang Xiaotao said, Zhang Guanyu nodded in response.

"Boss Yang, you say!"

"Well, this three-roller rolling mill is done, but it is not the end."

"Foreign six-roller rolling mills have been made. How big is the gap? It cannot be summarized by a simple one, two, three."

After Yang Xiaotao finished speaking, he looked at Zhang Guanyu seriously, "So the task assigned to you is to make a four-roller rolling mill, or a higher six-roller rolling mill..."

"In the future, our domestic steel mills can also use the rolling mills they produce."

"This is of great significance to national development and revolutionary construction. You must work hard!"

Zhang Guanyu looked excited. Boss Yang entrusted them with such an important task, which itself showed his trust and respect.

"Don't worry, Mr. Yang. Our R&D comrades will definitely go all out to complete the assigned tasks."

Zhang Guanyu shouted loudly, and Liu Daming and others who were busy on the side opened their mouths. They were also part of the R&D team, but they were not sensitive to what Yang Xiaotao said.

Of course, this is also related to their status. They are only responsible for doing it, and they still have to listen to the designers as to how to do it.

But if it is really completed, it will also be an honor for them.

"Don't be stressed. After this three-roller rolling mill is made, let the steel plant use it first. Let's do it step by step."

Zhang Guanyu nodded vigorously.
