Intelligent Industrial Empire

The construction of the wheat mobile phone factory is about to be completed, and now we are waiting for the assembly line purchased by Germany and some equipment for the production of mobile phone chips designed by the Rongcheng Electronics Research Institute to be installed.

According to Kmart Ren Zhiguo's news, the German equipment has been loaded on the ship, and it will be able to reach the Chinese customs in more than ten days.

As long as the equipment is disembarked, the four transport planes of September 1 Air will transport the equipment directly from Huadu Customs to Rongcheng. Yunfei is worried that the transportation of these equipment will be too bumpy and will cause certain damage to the German equipment.

You know, this is second-hand equipment, and the German side does not provide drawings.

Precisely because of this, the price is only 7 million U.S. dollars, if it is a new device, at least 10 million or more.Of course, the price of more than ten million will not necessarily be sold.

Germany is not so stupid. China's ability to copy is even better than Japan.

Especially the equipment that produces some simple electronic products, with China’s mechanical manufacturing capabilities, as long as there are drawings, they can definitely be imitated in a short time, even if the raw materials or processing accuracy are not good enough, at the cost of manufacturing in China, even if it is a It won’t be too bad to change it once a year.

Now that the mobile phone factory is waiting for the installation of equipment after the plant is built, and then waiting for the North Korean college student assembly line workers to enter China, Yunfei began to devote all his energy to the preparation of the vocational technical school of Jiuyi Heavy Industry and the acquisition of Rongcheng Tool Factory. coming.

Through the persecution of the base of the Ninth Hospital, Zhao Xingbang had no choice but to relocate the technical secondary school built in Dashan to train workers' children to Rongcheng. At the same time, the school began to apply for college qualifications from the Ministry of Education.

Most of the money for the relocation of the Jiuyuan Children’s School was paid by Jiuyi Heavy Industries. For this, Yun Fei spent more than 8 million yuan in funds. What he can say is the Mechanical and Electrical College of Jiuyi Heavy Industries which has complete autonomy. The teaching arrangements and the distribution of powers to those students’ graduation.

The two new machinery factories built by the Ninth Institute in Rongcheng Economic Development Zone, one was named Jiuding Machinery and the other was named Shenkun Technology.Just because of the names of these two factories, the Ninth Institute Base and the Aerospace Base almost got together.

When Zhao Xingbang asked Yunfei for the names of the two new machinery factories, Yunfei mischievously copied the names of the companies that were later restructured in the aerospace industry.Later, these two companies did not actually have any good benefits. Jiuding was just a restructuring of a workshop of only two or three hundred people in the aerospace base that produced automobile shock absorbers; Shenkun was also developed from a civilian workshop. The main production is some parts of mining machinery.

Yun Fei did not expect that these workshops in the aerospace base had not yet been completely relocated, and they had already begun preparations for restructuring.

It's hard to die, their two workshops are also going to be called by this name.

If it hadn't been for Zhao Xingbang to register with Xiang Rongcheng Administration for Industry and Commerce, those people in the aerospace industry would have no choice, and they didn't know how big things could be.

Anyway, the situation where the Ninth Academy Base and the Space Base are not dealing with each other has been going on for decades.

Especially in the past few years, there were not many military orders, especially the production and manufacturing of short-range missiles, which were robbed by space bases. The Ninth Institute had to focus on air-to-air missiles and air-to-air missiles that were completely unfamiliar to them. Go above the study of mines.

In this regard, Yun Fei has been criticized.

The Ninth Institute is nothing but a base for making guns and artillery, and by the way, it engages in conventional weapons research. At first, I didn't know what the high-level people were crazy about. They had to start the research and production of short-range missiles in the Ninth Institute.

The aerospace industry was originally a research and production base for the production of missiles and rockets. It was also the leaders of higher-level departments that they began to engage in research and production of conventional weapons, but mainly on some heavy howitzers.

When the state was planning the economy, the two bases that were very close to each other were able to live in peace. Regardless of the amount of production, the wages and bonuses are the same, neither more nor less.However, after the international situation has changed, the national strategic focus has been adjusted, military orders have dropped sharply, and a competition mechanism has begun to be established. How can the two bases that have many overlapping production tasks avoid conflicts?

"Boss, we don't even fully understand the technology of the three-axis machining center now, and we are starting to work on a fast electric spindle. Is this step a bit too big?" Sun Lin couldn't help but wrinkle when he heard Yun Fei's words. Frown.

He knew that he couldn't let this young boss idle.

When I am free, there will be a lot of whimsical ideas, but technical projects that are not easy to achieve.

"This is not inconsistent with our machining center research, right? Conventional spindles can no longer meet the performance of higher-performance CNC machine tools. We need to get ahead in research." Yun Fei shook his head.

It is difficult for traditional transmission mechanisms to increase the spindle speed of CNC machine tools on a large scale.

Yun Fei, who is a past person, knows that the spindle of the machining center becomes an independent electric spindle unit. That is the inevitable trend of the development of the machining center, because only the machining center with a wider spindle range can adapt to the constantly changing products and materials.

In the future China's mechanical processing market, as long as the processing plant products are small batches of single-piece production.

Especially the processing of high-precision and complex parts can only be processed with tens of thousands of revolutions or even tens of thousands of revolutions.

The higher the spindle speed, the smaller the stress generated during the machining process.Especially for CNC milling machines or engraving machines, the tools used are very small. If the spindle speed of the machine tool is not high enough, the speed of the position on the center point of the tool tip will be lower, so the processed products will not meet the design requirements at all.

"Only by simplifying the mechanical structure of the main drive system of the machine tool, can it be easier to provide the performance of the machine tool. Now whether it is a pulley drive or a gear drive system, if we want to increase the spindle, in addition to increasing the number of gear sets, or using larger Power motors, I don’t think there is any way, right?" Yun Fei asked the technicians in front of him.

Everyone nodded.

Machining centers and CNC milling machines are different from CNC lathes. The spindle that produces the main motion for high-speed rotation has to constantly move up and down. If the spindle unit is too heavy, it will not only cause serious wear on the guide rail, but it will take a long time because of gravity. The relationship makes the column of the machine tool deform.

"You mean to integrate the functions of the machine tool spindle and the spindle motor?" Sun Lin was surprised and Yun Fei, the kid dared to think.

At the same time, the graduate students of Rongcheng University he brought with him were also stunned. They only came to the Machine Tool Division of the Jiuyi Research Institute for a long time. Besides, they came here mainly to study. Who told them that their supervisor was for Jiuyi Heavy Industry. The young boss is working.

After knowing that academicians Sun Lin and Situ Heyun would not return to the National Academy of Sciences in the capital, many university leaders in Chengdu came to invite these top academicians in China to take master students or doctors to their schools. For graduate students, a few old guys originally disagreed, but Yun Fei was unwilling to give up so much labor that helped Jiuyi Heavy Industry research for free, so he encouraged several old guys to agree.

As a result, many talents in mechanics, mechatronics, or materials are assigned by Yunfei Network to its own banner. Although these people are likely to only stay in Jiuyi Heavy Industry for a few years, they are For nonsense, it is enough.

These are all students and don’t have to pay wages!

Moreover, they basically do some basic research work. Even if they develop any technology, they belong to the September First Research Institute. Although they are not paid, their research projects are funded by September First Heavy Industries. of!

"Yes, by combining the motor and the spindle in one unit, not only can the performance of our machining center's spindle be improved, but at the same time, the appearance of a lighter, high-performance spindle can also simplify our machine tool structure. , To reduce the difficulty of our assembly..." Few people know the advantages of the electric spindle system better than Yun Fei.

Electric spindle has the advantages of compact structure, light weight, low inertia, low vibration, low noise, fast response, high speed, high power, and simplified machine tool design. More importantly, it is easy to realize the precise positioning of the spindle.

The positioning of the spindle of the machining center is a very important indicator of the machine tool.

"Do you want to make the spindle unit of the machine tool independent? At the same time, directly adopt a direct, gapless transmission? How should such a technology be realized?" Although he is a top domestic expert, Sun Lin's imagination in this area is indeed limited .

The graduate students of Sun Lin from the School of Mechanical Engineering of Rongcheng University could only listen to their mentor discussing these advanced technologies with this little boss who was much younger than them.

Although they have studied for many years, they don't understand these technologies that they have never even heard of.

"Foreign countries have just begun to take off. This spindle unit mainly uses AC high-frequency motors for direct transmission, without indirect transmission. The electric spindle unit is mainly the electric spindle itself, we can regard it as a longer spindle motor; high-frequency inverter device , Mainly used to control the speed; built-in encoder, used to realize the control of the machine tool program transferred from the CNC system; cooling device, oil mist lubrication device, tool change device, etc..."

Yun Fei explained some of the structure of the electro-spindle he had learned, and at the same time drew a simple structure diagram of the electro-spindle with chalk on the huge blackboard in the conference room.

"Xiaoyun, how much did you spend to get this technology?" Sun Lin didn't believe that Yun Fei got such a picture without spending money.

Although it is very simple, but with this sketch, they can avoid many detours in their research.
