Zhao Zhongyao was telling the truth. He was not originally a military expert in designing weapons. He was originally a physicist. It was only after he was reborn in this parallel space that due to some work reasons, he began to learn how to design weapons blueprints.

Everything is self-taught. There was no teacher at all to teach him. He is completely self-taught. It's not what Zhao Gang thought. Zhao Zhongyao graduated from some professional military academies. The guns and weapons designed now were also learned at that time.

"Ah, Director Zhao, you turned out to be self-taught! I really admire it." When Zhao Gang heard Zhao Zhongyao's words, he naturally admired him very much.

After hearing this, Zhao Zhongyao reached out and patted Zhao Gang's shoulder with a smile, "You can do it too. As long as you have the determination, there is nothing you can't do."

"Well! Okay, thank you Director Zhao for your encouragement, I will work hard."

After listening to Zhao Zhongyao's words, Zhao Gang became more confident in learning weapon design in his heart.

"Oh, what did you come to see me for?"

After Zhao Zhongyao talked with Zhao Gang for a long time, it suddenly occurred to him that he must have something to do when he came to find him, not to see the drawings of his design 47.

"Director Zhao, what you said, I almost forgot. I came to see you for business." After hearing what Zhao Zhongyao said, Zhao Gang realized what he was doing to beat Zhao Zhongyao.

"What's the matter? Is it about the production of weapons?" Zhao Zhongyao didn't have to think about it. Since Zhao Gang came to him, something must have happened in the production of weapons.

Zhao Gang nodded first, and then said: "That's right, Director Zhao, we started producing weapons very smoothly. But when we produced the barrels of this gun, we encountered some problems."

"Oh, what's the problem, tell me, and I'll see if I can help you solve it."

As soon as Zhao Zhongyao heard Zhao Gang's words, he asked him what was wrong, so that he could help them solve it.

"Director Zhao, it's like this. When we produced the barrel this time, the electric drill on the milling machine was not long enough, so we couldn't mill out the rifling inside the barrel. What do you think we should do?"

After Zhao Gang finished speaking, he looked at Zhao Zhongyao quietly, hoping that he could think of some solutions.

After Zhao Zhongyao heard it, he thought about it carefully. He had some knowledge about the rifling of the barrel. After all, he was also an old military fan in production, and he also knew something about the processing of barrels.

The spiral grooves processed on the inner wall of the rifled gun are called rifling, also known as rifling. Among them, the convex part is the male rifling, and the concave part is the female rifling. The section of the barrel that is engraved with the rifling is called the rifling and is the main part of the barrel. Rifling is the bullet inside the chamber of the gun

And the main space for acceleration makes it have enough angular velocity to rotate around its own axis to maintain the stability of space flight. The marks formed by the rifling on the bullets have the highest identification value among the 29 bullet marks, and they can often provide some of the most valuable information, such as the type, model, manufacturing process, and degree of newness of the gun. The application of rifling has a history of hundreds of years,

The rifling of the barrel can also be solved on the lathe. You can mill the tailstock part of the lathe into a spiral shape. It is designed according to the lead of your barrel and install an alloy head on it. There are 4 or 6 pieces Cao, so that the rifling can be squeezed out

In fact, a qualified barrel must have a well-designed and proportioned material in advance. For example, a certain proportion of tungsten can prevent the barrel from becoming soft after continuous shooting, and a certain proportion of carbon can increase the rigidity and make it stronger.

Zhao Zhongyao thought about the knowledge he had learned about the rifling of gun barrels in his heart, and thought, to solve this problem, he had to redesign a drill on the milling machine so that this drill could mill the long guns of this new gun Tube.

It should be said that there is no difficulty in designing such a new drill bit, that is, it needs to be longer than the previous one.

The problem is that they don't have much time to produce new guns. If another drill bit is redesigned and produced again, it will take several days at least! In that case, it would be impossible for them to produce the new gun within two weeks.

"What to do, what to do." Zhao Zhongyao's mind was spinning rapidly.

"It seems that it is too late to design another drill bit. I can only modify the drawings. Anyway, this is a new gun, and no one knows what it should look like. Now I will change the drawings. , that's no big deal."

Of course, Zhao Zhongyao hasn't been to the scene to see the actual situation, so he can't say that he wants to modify the drawings first. After all, the things on the design drawings have been reviewed by the superiors. If they are modified casually, the superiors will naturally be unhappy of.

Thinking of this, Zhao Zhongyao said to Zhao Gang: "Come on, let's go to the workshop first, and I will find a way for you."

"Oh well!"

Zhao Gang had no choice but to come out of the factory director's office with Zhao Zhongyao, then went downstairs again, and came to the production workshop.

When Zhao Zhongyao saw a gun barrel being processed on the milling machine, he felt that the drill bit of this milling machine was indeed a bit short. Because the barrel of this gun is nearly ten centimeters longer than ordinary rifles! There are five hundred and eight millimeters. And the hour on this kind of milling machine can only drill to 500 millimeters at most, and there is only 8 millimeters to go through such a gun barrel. If it cannot be drilled through, of course the drilled barrel is useless.

The barrel is cold-forged from high-strength steel, and the chamber and barrel are chrome-plated. There are ring-shaped heat dissipation ribs on the outside of the barrel, and there are eight shoots at the end of the chamber of each barrel, which are used to lock in the steel connecting sleeve in the receiver, and the bolt is fixed on the back of the connecting sleeve.

department. The barrel connecting sleeve is fixed on the right side of the receiver with a spline, and the connecting spline coincides with the shoots on the barrel and bolt. When the barrel and bolt are in the connecting sleeve, their surfaces are completely engaged to form A closed air ring.

The barrel is the most important part of a gun. The quality of a rifle depends on the production technology and process of the barrel. If something goes wrong when processing the barrel, then no matter how good the gun is, it can only be a waste product.

As an old military fan, Zhao Zhongyao naturally knew the importance of the barrel to a gun. Now that something went wrong when making the barrel, he certainly couldn't take it lightly. Must find a way to solve this problem.

But Zhao Zhongyao was thinking about it, and there was no other way. It might be too late to redesign a milling machine drill. It is also a troublesome thing to modify the drawings. First of all, these two old guys probably won't agree!

After weighing it, Zhao Zhongyao decided to choose the latter. Because the two old fellows might be able to persuade them with some words.

But to redesign a milling machine drill bit, that is a troublesome thing, and it may take several days to complete!

"Director Zhao, what do you think we should do now! Workers, I'm just waiting for your decision!" Zhao Gang saw that Zhao Zhongyao was also at a loss, so he had to ask again.

"Hey! Let's modify the drawings!" Zhao Zhongyao sighed first, and then looked at Zhao Gang and said such a sentence helplessly.

"Modify the drawings!"

As soon as Zhao Gang heard Zhao Zhongyao's words, his eyes widened immediately. You know, he has never experienced this kind of thing. He has worked in the military factory for seven or eight years, and produced a lot of various guns and weapons. He never said that when producing a new weapon, he would modify the blueprint during the production process. This is something that has never happened before.

"That's right, this is the only way to go now. Because it would take several days to redesign and produce a drill bit for a milling machine! If that were the case, it would be impossible for us to put the three experimental guns together within two weeks. Produce it."

Zhao Zhongyao looked surprised at what Zhao Gang said to him, so he had no choice but to explain.

"Director Zhao, it's just that the drawings were designed by experts Zhang and Chen, will they agree to modify the drawings!"

As soon as Zhao Gang heard Zhao Zhongyao's words, he felt that this method might be a bit difficult!

"If they don't agree, they have to agree. What can we do? If we don't need it in such a hurry, we can naturally produce it slowly. But now the time is tight, and this gun is going to participate in the country's light weapons exhibition! There are only half a month left. It's time, we must produce this gun ahead of schedule."

Of course Zhao Zhongyao knew that these two old guys would disagree. Who wants to modify the drawings he has designed, which is disrespectful to the designer.

"Then listen to Director Zhao, and do whatever you say!"

Although Zhao Gang was surprised, there was nothing he could do. There is only Zhao Zhongyao to negotiate with the two old guys.

"Okay, call the two old guys over here! I'm going to talk to them face to face." Zhao Zhongyao knew that this matter had to be explained to the two old guys on the spot, otherwise, they still wouldn't believe what they designed The barrel cannot be processed on this milling machine!

After hearing Zhao Zhongyao's words, Zhao Gang had no choice but to nod, then walked out of the workshop and walked towards the office building.

The two old guys naturally wouldn't stay in the workshop all the time. They went to the workshop one day, in the morning, to see how the new parts produced by the workers were, and to see if the size was up to standard. Then I went back to my office in the afternoon, smoking and chatting!

It was already afternoon, and the two of them were smoking and chatting in the office, feeling very happy. Because they have already seen that the new guns they designed will be produced soon. At that time, the new guns they designed will be recognized by the market at the national light weapons exhibition, and then bring back many orders. The two are the heroes of the 308 base, and the superior leaders will definitely give them both spiritual and material rewards.

"Old Zhang! How about this new gun you designed? It looks pretty good, don't let it look fancy but not useful."

Chen Dongshan liked to make jokes about Zhang Lianying, so while smoking, he looked at Zhang Lianying next to him and asked.

"Old Chen, why are you so wordy! Didn't I tell you that the gun I designed is the most advanced gun in the world, so how can it be fancy but not useful! When it is produced, I will let you Try firing a few bullets, and you will definitely feel that the shooting accuracy and range of this gun are quite amazing.”

Zhang Lianying knew that this gun was not designed by himself, but was given to him by a classmate of his who was studying abroad. It was this classmate who had seen a new conceptual gun weapon from some internal military publications.

And the country's military industry level is the highest in the world. The new weapons designed by others are naturally the most advanced in the world. Since this kind of gun is a conceptual weapon designed by others, it means that in the future, the army of other countries will generally use this kind of gun!

Since it is a gun designed by a superpower, how can it be fancy but not useful. It is only good-looking and useful, and it is more advanced than the light weapons of most countries in the world, so how can it be inferior to ordinary guns and weapons.

Zhang Lianying was naturally very confident and didn't take what Chen Dongshan said at all.

After hearing Zhang Lianying's words, Chen Dongshan naturally had nothing to object to. He took a puff of cigarette, and after blowing it out from his nostrils, he looked at Zhang Lianying again and said, "Hey, Lao Chen, I suddenly thought of a question!"

"what is the problem?"

Zhang Lianying had already finished smoking one cigarette, and just wanted to get another one from the pack. But as soon as he heard Chen Dongshan's words, he immediately put the cigarette case on the table again.

"You said that the gun you designed was designed by an old expert. The gun designed by him must meet the processing dimensions of some machine tools in their military factory. However, our machine tools and other machine tools, It’s definitely not exactly the same. You said you didn’t design the drawings yourself, but just copied other people’s drawings, so can all the parts of your gun be produced in our workshop!”

It seems that Chen Dongshan is still a very careful person. When designing various bombs, he must consider whether the size of his design matches the maximum size of the machine tool in the workshop!

If the dimensions on the drawings you designed are different from the dimensions set on the machine tools in the workshop, which is beyond the scope of machine tool processing, then how can the designed weapons be produced smoothly.

Zhang Lianying was very confident in the gun design he copied. Because he only considered that this design was designed by military experts from China, a super military power, and it must be the most advanced light weapon in the world.

When he plagiarized, he naturally didn't consider any contradiction between the dimensions on the drawing and the machining dimensions of the machine tool in the workshop.

Now when he heard Chen Dongshan's words, he suddenly felt a little worried. After all, this was something he hadn't considered before.

It's just that Zhang Lianying has been bragging in front of Chen Dongshan how powerful the gun he designed is. Now that the gun he designed might not be able to be produced in the workshop, then all his boasting before would be nonsense.
