(I''m really sorry, the first two in 2021 can only be changed once. There was a real delay. Two shifts will be restored tomorrow. I''m really sorry.)
Wei Jianjun and others are going to faint.
How can you say change.
You know, the automobile of Daqin heavy industry is now the first private enterprise in China.
There are no rivals in domestic independent brands.
If we only talk about the sales volume of SUV, the sales volume of SUV is not as high as that of Daqin heavy industry, regardless of which brand or model.
Today, the sales of Qinfeng SUV, the first multi-functional medium and large SUV of Daqin heavy industry - Fusu, exceed 10000 every month.
This is a great sales achievement.
There are no rivals in the whole SUV sales. The rest are not broken. Two or three thousand a month.
Qin Feng and Fusu sell more than 10000 yuan a month. What''s the concept!
Although the price is not high.
The entry-level model is only 98000 yuan, and the top matching is only 128000 yuan.
This price is very low.
But because of the high sales, the quantity increases and the natural cost decreases.
The profit of each car exceeds 5000 yuan.
This refers to net profit.
Of course, this is not comparable to the profits of joint venture cars and pure imported cars.
But this is already very high.
The net profit of a car is 5000 yuan. If there are 10000 cars per month, the net profit is 50 million.
There are 600 million a year.
This is net profit.
Net profit excluding costs, labor wages, taxes and other expenses.
Real net profit.
This is the money in Qin Feng''s pocket.
In fact, if Qin Feng didn''t require very strict quality control and high quality control, there would be no problem in doubling the profit.
A car makes ten thousand, which is not much.
In that month, the net profit could be 100 million.
But Qin Feng''s requirements for quality control are too strict.
What is strict?
For example, when assembling the motor connecting wire inside, the worker sometimes accidentally made a small mistake and broke a little skin on the insulating protective layer outside the wire, which had no impact.
Just stick it together with insulating tape.
It''s assembled anyway. I can''t see it. There will be no problem.
At most, it takes a long time, because the internal high temperature inside may lead to excessive oxidation of the insulating tape and some falling off, resulting in possible damage to the wires.
This damage may not be fatal. It''s just that the power supply may be a little insufficient.
Moreover, it is by no means recent. It may be that after three or five years of driving, the power supply of wires may not be stable enough, which will make the output of the whole car not smooth enough. However, it does not affect the use. It''s just a little problem.
It can be said that this does not affect the use at all. And it''s all a few years later. If you drive a car for a few years, what''s the problem.
However, Qin Feng absolutely does not allow it.
If something goes wrong, we must replace the wire and never stick it with an insulating tape.
Never allow.
There are also some spare parts that are absolutely required to meet the standard, and there can be no mistakes. Not even if it does not affect the use.
Because of the high standard of Qin Feng, it naturally leads to some additional losses in production, which also leads to a decline in profits.
However, Wei Jianjun and others also support it.
Because, any brand can win the market reputation only if the quality is well done.
Otherwise, it will end sooner or later.
Even if consumers will pay for cheap, they will leave consumers with a low-end image.
Because you are low-end, it is easy to break. This is acceptable.
But in the future, if you want to establish a high-end brand, it will be difficult for consumers to change their inherent thinking and cognition.
Of course, what Wei Jianjun and others want to say is that they make so much money every year. Qin Feng didn''t take any money away. All of it was used to invest in self-developed engines.
Finally, in the past two years, they have been throwing money. In addition, they have stolen a lot of things from Audi''s German headquarters.
Finally, something has been achieved.
If everything goes well, this year, that is, in 2000, Daqin heavy industry''s cars may use self-developed engines.
Although the performance can not be compared with the first-class products in Europe and America.
At least 10 years behind.
Of course, this is a very good result.
You know, before Qin Feng ordered the development of engines, civilian automobile engines were more than 20 or 30 years behind.
It''s good to be more than ten years behind now.
This mainly depends on Qin Feng and Audi reaching an agreement to let people go to Audi to learn art.
At Audi, I didn''t learn any technology about engine manufacturing.
However, Qin Feng learned a lot about the assembly process.
Generally speaking, there are five main details of engine R & D.
One is metal casting. Engine cylinder body and other simple structural parts are generally formed by metal casting, and the specific process is divided into high-pressure casting and low-pressure casting. The metal melts into liquid and pours into the mold. The difficulty in this process lies in the occurrence of defects caused by residual stress, exhaust and release agent spraying during cooling and solidification. Defects reduce the yield and seriously affect the service life, because metal fatigue is most afraid of defects. Secondly, the quality requirements of metal materials themselves are also very high, generally cast iron or cast aluminum. High quality casting raw materials have not been available in countries and need to be imported from abroad.
Qin Feng naturally has no way. Even if Wei Jianjun and others have strengthened the research and development of high-quality cast aluminum raw materials to meet the needs of engines, it can only bring benefits in the future. In the short term, there is no result at all.
Thirdly, the best die-casting molds and machines in the world are Japan and Germany, then Italy, and then others. The mold should be precise, durable and suitable for automatic production. It can''t be said that several molds will break or leak after casting, or it can only be watched and controlled manually. The problem of metal casting is a huge problem. It is impolitely said that it has been a problem in China since ancient times, from the sword against the full moon machete to the current engine manufacturing. This technology is the product of the typical steam age and the foundation of all modern industries. Now they have cooperated with the electrical industry and computer information industry.
The second problem is machining.
Excellent machining requires good lathes, turning tools and lathe workers. Lathes and turning tools can at least be bought from Germany at a high price, but the lathe worker is a problem. When the same part is cut out in different directions and routes, the service life is obviously different. What about these skills. The piston of the engine needs to move back and forth thousands of times in the cylinder hole, and its error requirements are very high. The wall surface processing requires a process, called honing, to ensure the wear resistance of the cylinder hole surface and attach a layer of oil film to ensure the sealing performance. At this time, the honing material, process and direction came again. This process is not good. Even if the cylinder hole bends a little, the movement of the piston thousands of times will accelerate the aging of the engine. Crankshaft hole is a multi gear intermittent long hole, and each requirement of dimensional accuracy, roundness, coaxiality and surface roughness is very strict.
In this regard, Wei Jianjun and others have not learned. In Germany, it is impossible to cultivate this technology for you. It can never be given to you.
The third problem is the assembly process.
After reading speed and passion, I think that cars can be built by several people screwing screws and hanging platform engines in the warehouse. Those are car repairs, just car repair skills. The assembly inside the engine is not a single hand, but a professional assembly tool. These require experience, technology and time. Some parts need specific machines for installation, and even the installation sequence and tightening force of screws need experience and instruments. If fine hard particles are mixed into the piston gap, how much damage will be caused by thousands of grinding. Therefore, the requirements for assembly environment, process, equipment and technology are very high. Generally speaking, if the first two steps are not good, you don''t even have the opportunity to practice assembly.
Fortunately, Qin Feng arranged people to study at Audi headquarters in Germany.
Audi headquarters, because Qin Feng sells well in China, so it doesn''t embarrass Qin Feng. In other aspects, it was impossible to give Qin Feng any help, and he blocked Qin Feng''s side.
However, in terms of equipment and technology, the workers of Daqin heavy industry have been given a real opportunity to learn.
They really assembled the whole Audi vehicle inside.
It can be said that there is a small gap between Daqin heavy industry and Europe and America in vehicle assembly.
Thanks to the support of Audi headquarters in Germany.
Of course, everyone gets what they need.
But it is not easy for Qin Feng.
This is also a very key reason for the good quality control of Daqin heavy industry''s cars.
The fourth problem is rubber.
In the third problem, organic materials need to be used in the assembly process. Some people say that the engine is the resonance of steel and rubber. It''s good. It is not too much to say that rubber is the core material of internal combustion engine. Rubber plays a decisive role in the tightness of cylinder, oil tank and water tank. There are many engine assembly videos from large foreign automobile manufacturers on YouTube. After reading them, you will find that even those who screw the screws are handsome men, and their education is by no means low. For automotive engine rubber, high-quality rubber is also key. In this regard, it can only be imported.
The fifth problem is the main mechanical parts.
Cam, crank, connecting rod, gear set, bearing, chain and hydraulic parts are one thing that can be made, and another concept is that they can be used stably for a long time. In the final analysis, there are still two problems: metal materials and machining. The machine that makes the machine is the lowest and most NB guy. As the saying goes, if you want to attack it first, you must sharpen its tools first. Therefore, the iron still needs to be hard. If there is something at the bottom, there is everything. The hammers of Japan, Germany, the United States, Russia, Italy, France and Britain have been worn for a long time.
In this regard, Daqin heavy industry still has a long way to go.
But now, it has taken a step.
A very steady step. As a result, Qin Feng now said that he wanted to get an electric car?
Wei Jianjun and others all want to strangle Qin Feng.
As for why the domestic manufacturing industry is not developing well, there are also reasons.
First, we should distinguish two concepts: Science and engineering. Science is shared, transparent and open, but engineering is confidential and private. The principle of the engine can be said to be extremely simple, and this principle has never changed in the existence of the internal combustion engine for more than 200 years: the gas expansion caused by fuel combustion drives the piston to do work. But science is easy to say. How to make engineering according to human will with these boiled water theories known to mankind is quite another matter.
How to raise the power, reduce the weight, prolong the service life and improve the efficiency can be said to be an endless long march. We can all remember the scientific conclusions. I believe our higher science education in memory is very successful, but the engineering education in traditional industry can be said to be a mess, and the production technology is seriously divorced from the theory.
Another, before mankind entered the electrical age, there was a special period in western countries. This period was a period of rapid development of mechanical industry, known as the "big steam age". If you are interested, you can search the works in this period. Almost all the moving things are gear machinery, and its prosperity is unprecedented. Because China did not accept the baptism of this period, a small number of national assets were later disabled by imperialist oppression, and then filled by socialism, so there was basically no technological accumulation.
The core of Engineering accumulation is two words: secret recipe. Whether it is cooking, brewing, pharmacy, steel smelting and processing, its technical essence is no more than these two words. The secret recipe is completely private, which is generally inherited in the form of family or company. Inheritance needs time precipitation and national atmosphere. A nation that advocates speed, dare to challenge human limits and dare to question authority will have enough power to develop this iron and fire machine. I don''t think we did a good job in this. Our education doesn''t seem to encourage the cultivation of this adventurous spirit.
At the same time, some previous strategies also have problems.
I''ve been saying that market for technology. This refers to the strategic decision of the state to allow foreign capital to enter China to build automobile joint venture factories from the late 1980s to 2001 before China''s accession to the WTO. If we give up a huge market, we are qualified to want technology and profits. " In other words, we open the market in exchange for technology. Personally, this is a very naive theoretical hypothesis that stays at the macro level.
First of all, it is a general trend for the state to open its market. If it goes along, it will prosper and if it goes against it, it will die. Whatever the purpose, the market will open. There are only 200000 cars in the vast territory of 9.6 million square kilometers, with an average of 48 square kilometers. What kind of scene is this?
People all over the country can''t ride bicycles. Second, it greatly underestimates the value of science and technology. It is wishful thinking to change technology. I''m afraid the value of those important technologies will scare everyone. It''s far from what you can buy with millions of cars. Germany has five pillar industries, four of which are related to automobiles. The automobile industry has become the foundation of a big country. How can we talk about "changing"? The progress of core technology should never expect others to give us; Or what I said above, there is no shortcut. It''s really naive to place technological progress on others. It is this excuse of "market for technology" that stifles the driving force of independent research and development.
So don''t think about "changing technology" any more. Die hard. You can''t steal it and you can''t rob it. After all, the growth of national industry needs a process.
