Siheyuan: Craftsmen of a Great Country

Huge problem?

As soon as these words came out, everyone's expressions changed.

Everyone looked at me and I looked at you, and we all saw confusion from each other's seriousness.

Jiang Chen said: "I just asked everyone to feel it carefully, didn't you all notice?"

There was silence.

After a long time, Liu Xi said: "Gong Jiang, we have just operated the machine tool and experienced it carefully. We did not find any problems."

"And the performance of this machine tool is already so superior. Are your requirements too high?"

Jiang Chen shook his head: "It's not that the requirements are high, but the problem is real."

Liu Yue raised her hand carefully and said, "I found something unreasonable. I don't know if this is what the leader said."

Jiang Chen looked at Liu Yue: "Tell me about it."

Liu Yuedao: "When I was operating, I found that the machine tool was running too fast and the output power was too high. At our operating speed, there is no need for such high power."

"I don't know if I'm right."

Jiang Chen gave Liu Yue a thumbs up: "That's absolutely correct, that's the problem."

"The output power of a machine tool is not higher the higher it is. When its running speed exceeds our reaction speed, the excess power is useless work."

"No, it's not wasted work, it will have the opposite effect. Running too fast will not only waste energy, but also affect our operating accuracy, accelerate the loss of parts, and affect the life of the machine tool."

After listening to Jiang Chen's explanation, everyone thought carefully and realized that this was really the case.

But if you think about it, this doesn't seem to be a big problem.

Running faster, wasting a little energy, and accelerating some losses will not affect the value of this machine tool.

As for using huge problems to describe this trivial matter?

Jiang Chen saw the dissatisfaction in everyone's eyes: "You may think this is a small problem, but think about it, if the operation is too fast, any small mistakes we make during the operation will be magnified, leading to production failure. .”

"We are all senior workers, so the error rate is low. But don't forget, machine tools are for use by workers, and they may not have as high a level of skill and proficiency as you."

"Even occasional mistakes will have a huge impact on production efficiency. Not to mention the impact of material waste mentality and other issues."

"Any problem that affects production efficiency and causes waste of valuable materials is not a small problem."

Everyone lowered their heads.

If you want to adjust the output power, you need to adjust the transmission system.

The transmission system is the core component of the machine tool, affecting the whole body.

Once it is changed, it may be a major change.

It's not that they're afraid of change, it's just that their early efforts have been negated, and they feel extremely frustrated.

Jiang Chen asked Liu Yue: "Since you can discover this problem, how do you think we should solve it?"

Liu Yue looked at Jiang Chen's encouraging eyes and typed out the order: "Adjusting the ratio of the gears can adjust the output power on a certain Chengdu."

"So I think we can solve this problem by adjusting the ratio of the transmission gear to a smaller ratio and then reducing the energy consumption of the motor."

Seeing the corners of Jiang Chen's mouth raised slightly, Liu Yue knew that she was right.

Qin Kai slapped his thigh: "Yes, why didn't I think of this kind of operation?"

"The transmission devices are linked by gears. The larger the ratio of the gears, the faster the pinion rotates. This will cause the output power to be too high, and the pinion will consume more energy to drive the machine tool."

"If we make the pinion bigger, we can solve this problem. Why do we have to think about adjusting the transmission system?"

"Liu Yue, you are great. How did you come up with this method?"

Liu Yue whispered: "When I was reading with the leader, I read some of them by the way, but I didn't expect to use them today."

In fact, that's not convenient.

Jiang Chen specially picked Liu Yue to stay on this page for a long time when Liu Yue was around, and added the underline for emphasis. He simply deliberately let Liu Yue see it and gave her a chance to show off.

Fortunately, Liu Yue did not disappoint him. We thought of it at the critical moment and applied what we learned.

Jiang Chen said: "Now that we have a solution, we must find the most reasonable ratio next."

"This ratio is our rotation speed, which is just a little faster than our most skilled workers."

Qin Kai said: "This is simple. You can calculate it through calculation. Leave the dimensions to me and you can be responsible for the production."

Jiang Chen said: "Okay, let's do it!"

If there is an error in the proportion calculated by Qin Kai, he will point it out in time to avoid wasting too much time.

The productivity of current machine tools is roughly equivalent to 1.8 to 1.9 times that of the big brother's castration machine tools.

The machine tools provided by the system are 2.2 times.

There is a problem with gear ratio.

After correcting this problem, the production can be a little more than twice that of the big brother machine tool.

What remains is the productivity lost by having to give up pursuing extremes for some parts in order to achieve mass production under a weak industrial foundation.

But even so, this machine tool can be regarded as one of the more advanced machine tools in the world.

With the direction, the rest of the production is not difficult.

After a day off on Sunday, on Tuesday, December 12, the final version of the machine tool was finally officially launched.

Having learned from the past, although everyone was excited this time, they were much calmer.

Then various tests were carried out in an orderly manner.

After preliminary testing, there were no problems, and the production ratio was 205% of the castrated version of the big brother machine tool.

No further questions.

After the preliminary test, there is a long-lasting operation test.

This test lasted until the morning of December 12st.

It mainly tests the stability of its long-term operation, including but not limited to positioning accuracy, processing capacity, control conversion system, safety, etc.

The performance of the machine tools in all aspects is beyond imagination.

If I have to mention any shortcomings, it is that the tools wear out relatively quickly.

The knives are originally products purchased from the market and produced by flower growers, and their performance is average. Now that the production efficiency has increased, it is normal for the wear and tear to accelerate.

Jiang Chen is quite satisfied with this result.

Under such simple conditions and in such a short period of time, in a rolling mill engaged in steel processing, a machine tool with such excellent appearance and performance was produced, which is really shocking.

Although most of it is due to space, the benefits they can obtain are indeed real.

With this machine tool, Jiang Chen is one step closer to his ideal life.

Jiang Chen announced loudly: "Now I announce that the Scientific Research Laboratory of the Third Steel Rolling Plant, the first machine tool at the world's advanced level, has been successfully developed!"

Cheers suddenly echoed throughout the laboratory.

This time, everyone finally put aside their last worries and could enjoy the carnival.

Qin Kai cried.

As a real machine tool developer, he knows how difficult this is.

Liu Xi, Wang An and others are full of pride and joy. They have a share of this incredible contribution.

Shizhu took a deep breath, and the pressure that had been suppressed due to his low level was relieved.

Liu Yue jumped into Jiang Chen's arms excitedly. Anyway, after the last reading incident, their relationship was not a secret in the group.

Luo Xue was also looking at Jiang Chen, her thoughts becoming more and more determined, but at this time she couldn't jump into Jiang Chen's arms like Liu Yue.

After everyone reveled for a while, Jiang Chen said: "Everyone, clean up this place and prepare the materials. I will ask the factory director and representatives to come over this afternoon to review our research results."

"Maybe people from the Ministry of Industry will come too."

Everyone is looking forward to it.

Excellent works will be meaningless if they cannot be appreciated by more people.
