Smart Industrial Empire

The factory building of the wheat mobile phone factory is about to be completed, and now it is waiting for the assembly line purchased from Germany and some equipment for the production of mobile phone chips designed by the Rongcheng Electronics Research Institute to be in place for installation.

According to Kamat Ren Zhiguo, the German equipment has already been shipped, and it will reach China's customs in a maximum of ten days.

As soon as the equipment gets off the ship, the four transport planes of Jiuyi Airlines will directly transport the equipment from Huadu Customs to Rongcheng. Yun Fei is worried that the transport of these equipment will be too bumpy, which will cause certain damage to the German equipment.

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

It is precisely because of this that the price is only 700 million US dollars. If it is a new device, it must be at least 1000 million or more.Of course, if the price is more than 1000 million, no one will necessarily sell it.

Germany is not so stupid. China's imitation ability is even stronger than Japan's.

Especially the equipment for the production of some simple electronic products, with China's mechanical manufacturing strength, as long as there are blueprints, it can definitely be imitated in a short time, even if the raw materials or processing accuracy are not up to standard, with China's manufacturing cost, even if it is used It's not too bad to change it once a year.

Now the mobile phone factory is waiting for the installation of equipment after the factory building is completed, and then waiting for the assembly line workers from North Korea to enter China. Yunfei began to put all his energy into the preparation of the vocational technical school of Jiuyi Heavy Industry and the acquisition of the Rongcheng Tool Factory. coming.

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

Jiuyi Heavy Industry paid most of the money for the relocation of the Jiuyuanzi School.To this end, Yunfei spent more than 800 million yuan in funds. What he can say is that Jiuyi Heavy Industry has complete autonomy in the teaching arrangement of the School of Mechanical and Electrical Engineering and the distribution of graduation rights for those students.

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

When Zhao Xingbang asked Yunfei for the names of the two new machinery factories, Yunfei plagiarized the name of the company that was later restructured by Aerospace as a prank.Later, these two companies did not have any good benefits.Jiuding was restructured from a workshop in the aerospace base that produced automobile shock absorbers with only two or three hundred people; Shenkun was also developed from a civilian product workshop, mainly producing spare parts for mining machinery.

Yunfei did not expect that these workshops in the aerospace base have not yet been completely relocated, and they have already begun to prepare for restructuring.

Luckily, their two workshops are also going to be called by this name.

If it wasn't for Zhao Xingbang's registration with the Rongcheng Industrial and Commercial Bureau, the people in Aerospace would have no choice but to figure out how big of a deal it would be.

Anyway, the situation where the Ninth Academy Base and the Aerospace Base have not dealt with each other has lasted for decades.

Especially these years.Originally, there were not many orders for military products, especially the production and manufacturing of short-range missiles, which were all snatched by the space base, so the Ninth Academy had to focus on the research of air-to-air missiles and sea mines, which were completely unfamiliar to them. .

For this, Yun Fei was criticized endlessly.

The Ninth Academy is just a base for making guns and cannons, and doing research on conventional weapons by the way.At the beginning, I didn't know what kind of madness the high-level executives had, so they had to start the research and production of short-range guides in the Ninth Academy.

The aerospace industry is originally a research and production base that mainly produces guides and rockets. It was also the leaders of the higher-level departments who took the wind and asked them to start research and production of conventional weapons, but mainly on some heavy howitzers.

When the state planned the economy.The two bases that are very close can live in peace, regardless of whether they produce more or less.The salary and bonus are the same, neither more nor less.However, after changes in the international situation, the country's strategic focus was adjusted, and military orders dropped sharply. At the same time, a competition mechanism began to be established. The two bases have many overlapping production tasks. How can there be no conflicts?

"Boss, we don't even have a thorough understanding of the technology of the three-axis machining center, so we started to develop fast motorized spindles. Isn't this a big step?" Sun Lin couldn't help but frowned when he heard Yun Fei's words. frown.

He knew that the young boss couldn't be left idle.

As soon as I am free, there will be a lot of technical projects that are not easy to realize but will be proposed. [

"This is not contradictory to our research on machining centers, right? Conventional spindles can no longer meet the performance of higher-performance CNC machine tools. We need to go ahead in research." Yun Feiyao shook his head.

With the traditional transmission mechanism, it is difficult to increase the spindle speed of CNC machine tools on a large scale.

As someone who has experienced it, Yunfei knows that the spindle of the machining center becomes an independent electric spindle unit, which is an inevitable trend in the development of the machining center, because only the machining center with a wider range of spindle speed can adapt to the constantly changing products and materials.

In the future of China's machining market, as long as the processing factory products are all produced in small batches.

Especially the processing of those high-precision complex parts must be processed at a speed of tens of thousands or even hundreds of thousands of revolutions.

The higher the spindle speed, the less stress the part generates during machining.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 at the center point of the tool tip will be lower, so that the processed products cannot 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 achieve the performance of the machine tool. Now, whether it is a pulley drive or a gear drive system, if we want to increase the main shaft, in addition to increasing the number of gear sets, or I don’t think there is any way to use a higher power motor?” 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 and rotates at high speed has to move up and down continuously. If the spindle unit is too heavy, it will not only cause serious wear to the guide rails, but it will also be damaged due to gravity in a short time. The relationship makes the column of the machine tool deformed.

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

At the same time, the postgraduate students of Rongcheng University he brought along were also stunned. They have only come to the Machine Tool Division of Jiuyi Research Institute for a short time, and they are mainly here to study. The young boss is working part-time.

Knowing that academicians such as Sun Lin and Situ Heyun would not return to the National Academy of Sciences in the capital, many university leaders in Rongcheng came to invite these academicians, who are all top-level academicians in China, to their schools to lead master students or doctors. As a graduate student, the veterans originally disagreed, but Yun Fei was unwilling to give up so much free labor to help Jiuyi Heavy Industry in research, so he encouraged the veterans to agree.

As a result, many talents who study machinery or mechatronics, or materials have been brought under Yunfei Network's banner. Although these people may only stay in Jiuyi Heavy Industry for a few years, but for Yunfei In other words, enough is enough.

These are students, not paid!

Moreover, they basically do some basic research work. Even if they research any technologies, they all belong to Jiuyi Research Institute. Although they are not paid wages, their research projects are all funded by Jiuyi Heavy Industry. of!

"That's right, by combining the motor and the spindle in one unit, not only can the performance of the spindle of our machining center be improved, but at the same time, the emergence of a lighter, high-performance spindle can also enable Our machine tool structure is more simplified, which reduces the difficulty of our assembly..." Few people are more aware of the advantages of the electric spindle system than Yunfei.

The electric spindle has the advantages of compact structure, light weight, small inertia, low vibration, low noise, fast response, high speed, high power, and simplified machine tool design. More importantly, it is easy to achieve 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 direct and gap transmission? How should such a technology be realized?" Although he is a top domestic expert, Sun Lin's imagination in this area is really limited.

Sun Lin's postgraduate students from the School of Mechanical Engineering, Rongcheng University could only listen dumbfounded to their supervisor discussing these advanced technologies with this small 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.

"Now foreign countries have just started. This spindle unit mainly uses AC high-frequency motors for direct transmission without indirect transmission mechanisms. The electric spindle unit is mainly the electric spindle itself. We can regard it as a motor with a relatively long spindle; high-frequency frequency conversion device , mainly used to control the rotational speed; the built-in encoder is used to control the machine tool program transmitted from the CNC system; the cooling device, oil mist lubrication device, tool change device, etc..."

Yunfei told some of the structure of the electric spindle that he knew, and at the same time drew a simple structure diagram of the electric spindle with chalk on the huge blackboard in the conference room.

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

Although it is very simple, with this simple diagram, they can save a lot of detours in their research. (To be continued.
