After leaving the duck's matter to Qin Liru, Qin Yangtian was once again involved in the development of the car.

With a lot of knowledge, Qin Yangtian divided the personnel into many groups, and each group had only one research direction, and some progress could be made every day.

Since the success of the heating furnace, it has become easier to make some accessories.

Now Qin Yangtian is secretly studying the idea of ​​building a small truck.

In Qin Yangtian's view, small trucks should still have a large market, whether at home or abroad, especially abroad. As long as they are well made, they may be another foreign exchange-making product.

The first step Qin Yangtian wanted to do was the chassis of the car. He realized that the chassis of the BJ Jeep was still much worse. Now that we want to build a small truck, the chassis needs to be redesigned.

So, the first thing Qin Yangtian wanted to do was to build a stamping machine.

It is impossible for them to import this thing, and they cannot import this thing, they can only produce it themselves.

As Qin Yangtian's technology was constantly being produced and the factory had various materials, naturally, a large stamping machine was actually produced in the factory.

Looking at this developed machine, Qin Yangtian was in a really good mood. The automotive chassis press-forming hydraulic press has been created. This is the use of presses and molds to apply external forces to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining the forming and processing method of stamping parts of the required shape and size.

With this machine, it is no problem to stamp out any workpiece in the future.

Yi Zhongming walked to Qin Yangtian at this time and said, "This thing is very refined, and it has been developed in the end."

"Have you made the mold?" Qin Yangtian asked.

"It's already done, just waiting for the punch."

"Then try it."

Qin Yangtian directed everyone to start slamming the chassis of the small truck.

This is a key component of a minivan. If successful, the entire minivan will almost complete a part. In addition, the engine has been made, so there is actually no big problem in the manufacturing of the car.

Standing there, Qin Yangtian smiled when he thought about the manufacture of the engine. He had to say that the success of the stepping heating furnace saved him a lot of trouble. He was originally just a normal engine, but now the process improvement has been improved, and the car engine has been made.

When Qin Yangtian thought that the country spent a lot of money and so many people were doing research, he was not as advanced as he had created here, so he felt very happy.

This is why I have mastered more advanced technologies!

After mastering the manufacturing technology of automobiles, Qin Yangtian found that there were indeed many problems in the domestic automobile industry. When the first car in China appeared, it was more than 70 years behind the production of the first car abroad. This is not a simple number. In other words, the automobile industry in China lost at the starting line from the beginning. Without any foundation, it started from scratch together. Western countries that have mastered the manufacturing of automobile engines have adopted strict blockade measures for the key core technologies of their engines. It is impossible to spread the key core technologies by buying them!

Qin Yangtian also knows one thing, that is, the cost of engine research and development is high, and it takes a long time to achieve some results. The West has gone further, which is also a reason why domestic cars have never been better than foreign countries.

However, now I have a lot of knowledge in this area, and research and development is a joke. I just need to take it out by myself. There is no cost or time cost. Although China is still behind in all aspects, it can be made out once the basic things are available. This is also one of the reasons why he can make things so quickly.

With technology, when it is done, it is a problem of casting. China does not make masters, but still makes technology. In this regard, steel rolling mills have natural advantages. Qin Yangtian brought out the technology and allowed the masters to solve the problems and achieved results in engine casting.

The engine is made by casting. The main body of the engine cylinder and other simple structural parts are generally made of metal casting. The specific manufacturing process is divided into high-pressure casting and low-pressure casting. The metal melts into liquid and pours it into the mold. The difficulty in this process is that the residual stress, exhaust, mold release agent spraying, etc. during the cooling and solidification process leads to defects. The defects reduce the yield rate and seriously affect the product life, because metal casting is most afraid of defects. With Qin Yangtian's technology, the masters thought of some solutions, and this problem was naturally solved quickly.

Automobile engines have extremely high requirements for the quality of metal materials themselves, generally cast iron or cast aluminum. High-quality casting raw materials technology is not good in China and needs to be imported from abroad. Qin Yangtian took out this technology, so the material problem was also solved in the research.

In the following time, the engine's die-casting machine and die-casting mold were also successfully created.

In the mechanical processing technology, masters such as Yi Zhongming played a key role. Under the guidance of Qin Yangtian, the processing technology was constantly improved, and they solved some problems that were difficult for other factories to solve.

The engine has no problem, and it is now a matter of the body. After the stamping can be formed, some technologies such as transmissions, brakes, steering gears and other problems will be solved, and the car will be almost done.

With technology, there is naturally not much problem with these things.

You should know that the steel rolling mills had built many old experts living in cowsheds in various aspects in the early stage. After they obtained Qin Yangtian's technology here, they were all working hard to conduct research, and they had results every day and could produce a key technology every day. This development progress was something other factories could not catch up with.

The machine roared, and then, the chassis of a car was stamped out quickly.

Several masters rushed up immediately.

After everyone looked and looked, Yi Zhongming said excitedly: "Director, it's done!"

Qin Yangtian was naturally watching there, and when he saw that it was indeed consistent with his requirements, he felt very happy.

Now the tires are left!

Qin Yangtian scratched his head and felt that this matter really needs to be resolved as soon as possible. He doesn't like ordinary tires, and he can't make ordinary tires in the car he is working on.

It seems that you need to find a superior.

After arranging some things, Qin Yangtian thought about the situation of the car and found that there were two more problems, one was the problem of the headlights and the other was the problem of painting. These two also need to be paid attention to.

If you don’t do it, don’t do it. If you want to do it, just make a car that looks better than the BJ Jeep.
Chapter completed!
