Chapter 159: A lot of questions

Several people also tried to keep it as secret as possible, and it was impossible to tell Nastya that at most in a year or two, the equipment of the rolling mill would be updated, and at that time, cars would definitely be built, and Director Yang and they discussed what to build at that time. It's just that these must not be said to Nastya, for Nastya, Li Zhao is strictly guarded, and it is definitely impossible for outsiders to know the confidential content, that is, Li Zhao is suffering, and he needs to find a suitable reason.

And if you really build a car, there are two main problems that need to be solved, one is the problem of machining accuracy. Li Zhao is definitely reluctant to build a jeep like the 212, although this car is said to be very powerful, but the shortcomings are equally serious. Speaking of noise, when the 212 runs to a speed of 80 per hour, the noise will reach more than 80 decibels, which is already a noise level that can damage hearing, and if you accelerate, the noise will be even greater.

The main reason for all this is the problem of machining accuracy, and of course, there must be design flaws. It is said that there is a saying that if there are no parts missing from the 212 within a thousand kilometers, then you must have bought a fake 212, which shows how rough the processing technology of this car is.

The second problem is how to solve the problem of the production line, Li Zhao will definitely not let the workshop workers smash the car shell with a sledgehammer. Then the establishment of production lines and supporting equipment has become inevitable, this investment is very large, Li Zhao for Yang factory director can get this fund doubts.

You must know that there are a lot of stamping parts on the car, if each stamping part is equipped with a stamping machine with a die, even if it is relatively simple now, it will take thousands of stamping machines. You must know that the gas car is just the shell, which is put together by many steel plates, and many shapes are welded with separate steel sheets.

So if you want to really build such a production line, then just the stamping machine is a big investment, if each stamping machine makes ten kinds of parts, then it will take at least one or two hundred stamping machines. Coupled with the supporting molds, Li Zhao really didn't think that the rolling mill could come up with this money.

Of course, if Li Zhao builds a car, the advantages are still relatively obvious, first of all, there is no problem in the material, what performance materials are needed for each part, Li Zhao is also a door. And in terms of mechanical design, Li Zhao not only has the advantage of memory, but more importantly, his own design and optimization ability is also very strong, it can be said that Li Zhao has basically digested the mechanical aspect, but in terms of electronics, Li Zhao really has no way.

Therefore, if you build a car, the biggest problem affecting Li Zhao is the processing capacity, if the machine tools designed by Li Zhao can be taken out now, Li Zhao is sure to build a car that is twenty or thirty years ahead of this era. Of course, that's only mechanical, and Li Zhao can't help it in electronics. Of course, this point cannot bother Li Zhao for too long, once the new material factory is put into operation, when the funds are sufficient, Li Zhao will definitely set up a series of research institutes at the first time.

Now machining accuracy is a big problem, this problem is also related to the performance of the engine, air conditioning, gearbox, etc., the machining accuracy is too poor, it is really not as good as building a tractor. For tractors, stamping workpieces can save the vast majority, which can save a lot of money. Just like the shell of a tractor, it is just a thin iron sheet, and many people buy it back, and the first time they buy it is to remove the attached engine cover, which affects the heat dissipation of the engine.

The machining accuracy can also be appropriately relaxed, after all, the tractor of this era has not been so strict in terms of performance, and Li Zhao is fully sure of making a tractor that is ahead of the times.

Of course, if you really want to build a car, then now Li Zhao can start preparing the design drawings of the car, which is also a long job. Li Zhao's design must be imitated by others, even if it is imitated, it is only a little bit of polishing by senior technicians, and it is impossible to produce it on a large scale.

Of course, the design is also a problem, if Li Zhao designs it himself, Li Zhao estimates that it will take a few years, and the best way now is still to adopt the current model, Li Zhao provides detailed structural drawings, and the fine design is completed by the whole team. In this way, Li Zhao only needs a few hundred pictures to get it done, and the entire team needs to expand these to tens of thousands. If you add the drawings of various molds and equipment, it may take hundreds of thousands, and Li Zhao feels a headache when he thinks about it.

At this time, Director Yang said: "Why don't we also build some cars by hand, what do you think?" ”

When Li Zhao heard this, he smiled bitterly and said, "Is it really necessary for the factory director?" As for the dozen or so seventh- and eighth-level workers in our factory, if they do this, they don't have to do anything in a month or two. The final car may not work well unless you want to copy what is already on the market. Or the kind of tricycle we make in Shanghai, if you feel that the power is insufficient, you can also change to a diesel engine, otherwise we really can't mass production, the investment is too big, all the equipment is in place, and you need to invest tens of millions of dollars. ”

Li Zhao continued: "If I want to design, if I want to complete the design, it will take a year and a half at the earliest, this can only be produced to the structural drawing, and the most parts are clearly marked, and if I want to design a full set of production lines, it will take at least one team to work for one or two years." As he spoke, Li Zhao took his backpack over.

Li Zhao took out the drawings inside and handed them to Director Yang, which was the result of Li Zhao's recent evening, the tractor design that had not yet been completed. The number of horsepower selected is not large, only 20 horsepower, but compared with similar products, it is definitely more fuel-efficient, quieter and more efficient in power utilization.

To say the simplest example, the efficiency of this tractor designed by Li Zhao can definitely reach more than 80 percent, while ordinary tractors can reach 70 percent, and some can only reach more than 60 percent. Therefore, although the tractor designed by Li Zhao is twenty horsepower, the effective power can reach at least sixteen or seventeen horsepower. While others have twenty horsepower, the actual power may only be thirteen or fourteen horsepower, so what is shown is more powerful, and this design is where Li Zhao's confidence lies.

It's just that there are dozens of drawings that have not been completed, and these are mainly engine drawings, and the overall drawings have not yet been designed. However, the tractor is also simple, and Li Zhao mainly wants to engage in a series of engines, so when designing, he also thinks more. Li Zhaoke wants to rely on the advantages of materials, after the new machine tool is in place, to challenge in this era, to achieve all the transmitter models from 20 horsepower to 10,000 horsepower.

In the future, only need to continue to improve on the basis of this series, and the power system will continue to improve, so Li Zhao is particularly careful when designing. It is necessary to consider not only the limit of machining accuracy, but also the appropriate error under this limit, and to control the cost of this series of engines as much as possible. Finally, the power, fuel consumption, processing difficulty, and cost are achieved to an optimal result.

Seeing Li Zhao take out the drawings of the tractor, Master Zhang and Director Yang were surprised, but they didn't expect Li Zhao to start designing, Director Yang took a look at it and said: "This is a new engine drawing, twenty horsepower?" You start preparing now. If we are producing tractors, we have a full set of drawings in the rolling mill, where do we need another design. As long as we have a task, we can just start figuring out how to produce. ”

Li Zhao couldn't see Director Yang's resistance to the production of tractors, not only him, but also Master Zhang also hoped to be able to produce automobiles, and their army was also very short of cars. But Li Zhao really doesn't want to directly produce cars, the demand is too small, and now it takes him a few years to get the cars out, and he may not be able to sell tens of thousands of cars in more than ten years, hundreds of them a year, which is too little, and the investment is very large.

And Nastya is here, Li Zhao can't say his plan, Li Zhao first engaged in diesel engines, and he also has ideas. First of all, if there is progress in agriculture, then the demand for tractors can definitely take off in five or six years, and it will be absolutely no problem for rolling mills to sell hundreds of thousands of dollars a year.

The second is that Li Zhao needs to verify his design concept, if the design concept is appropriate, then Li Zhao is ready to engage in high-horsepower diesel engines, then after the 125 mm gun is made in the military factory, Li Zhao can make a quasi-third-generation tank. First of all, the power must reach thousands of kilowatts, so that it can drive the 50-ton car body, Li Zhao has no problem here in terms of machinery, so the main thing that is lacking is the electronic system.

This is equivalent to Li Zhao directly coming up with a quasi-third-generation weapon platform, so the follow-up only needs to be improved on this platform, but Li Zhao obviously can't say it here.

At this time, Nastya interjected: "You can produce cars first, the production line that can produce cars, and after adjustment, you should be able to produce tractors, right?" Li Zhao also admired Nastya's brain circuit when he heard it, which made more sense, but who could be so stupid to transform a car production line into a tractor production line.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
