Love in the Siheyuan: Starting from Jia Dongxu

When Jia Dongxu saw that the two workshop directors had already produced the parts, he quickly took them and looked at them. After thinking for a while, he asked Qin Fuhai to call Jia Anguo over to guard the production area.

By the time the two had finished producing all the parts, the firearms R&D personnel sent by the department had already been brought over by Wang Tongming.

The two men were worthy of being firearms researchers. They took the parts and assembled them in no time.

The two pulled the bolt, pulled the trigger, listened to the sound, and nodded, "No problem, it would be nice if we had bullets to try. That way we can feel the recoil and the firing of the bullet to reverse the charge."

"You two, regarding the firearms, I believe we have received orders. Our goal is to change the size of the bullets to our own country's bullets. Now we will leave the rest to you."

Jia Dongxu walked forward and handed over the size chart.

The two took it, studied it carefully, and then said when they saw the gun, speaking of automatic rifles, if the caliber of the bullet is not right, it is easy to miss the target or explode the barrel.

Then one of them took out a size drawing of his own gun barrel and handed it to Jia Dongxu, "Make the gun barrel as it is, with the outer dimensions according to the original drawing and the inner caliber according to our own caliber and let's see."

Zhang Huaiqing and Liu Zhonghua hurriedly took it and took a look. After thinking for a while, they adjusted the drill bit of the machine and started production.

The two men talked about adjusting the size of the place where the barrel and the bullet meet to increase the airtightness, so that the bullet would be fired more smoothly and with greater power.

After hearing this, Jia Dongxu immediately asked Jia Anguo to get domestically produced rifle bullets, and then set up a shooting range next to it.

The two carefully studied the structure of the barrel docking and the materials of the corresponding parts.

“According to our understanding of this gun, the caliber of the docking and the material of the spring are the key.

We need a softer spring, otherwise the spring is too hard and it is easy to jam when shooting.

But the spring cannot be too soft, otherwise the gun will be unstable and prone to misfire."

"Can we use the springs we produce now instead?"

Jia Dongxu thought for a moment and asked, "Is this the same as the guns we have now?"

"Well, we can give it a try, but these are minor issues. The main one is that our own steel will increase the weight of the gun, and the loose connection will cause problems with automatic loading." said another researcher.

Jia Dongxu thought for a moment and said, "Can we modify a gun like this based on the guns we have now, using its automatic loading principle?"

The design institute thought about it and said, "Well, probably not. This will affect the airtightness of the original gun and affect the shooting accuracy."

Upon hearing this, Jia Dongxu said directly, "First design and find out what the problems are, so that all the modifications are based on our own caliber, and then solve the problems in a targeted manner."

The two technicians looked at each other. Now they knew that this young man was currently the head of the R&D team.

He said nothing more, took out the blueprint of our own rifle, and started writing and drawing on a piece of white paper, directly transforming the appearance of our own rifle into the shape of Mao's.

Then they began to continue measuring and modifying the internal structure. Several people surrounded the two technicians and did not dare to breathe, for fear of disturbing their inspiration.

During this time, Wang Tongming had people bring tea and other things, but the two of them were unaware of it. They just felt that their minds were opened up. They argued from time to time, discussing what materials to use in what places, what the thickness was, and what problems would be encountered during docking.

Jia Dongxu pulled Wang Tongming over and asked softly, "Brother Wang, where did the minister find these two treasures? It's amazing that they know so much about the materials and the finished products."

Wang Tongming couldn't help laughing when he saw the two men. "Haha, I don't know about this. It may involve some confidentiality agencies. Anyway, we have to use them well."

Due to the differences between the two in some material and size modifications, these differences were recorded during the design process and then the next step of deduction was carried out.

During the design process, the two of them actually operated the machine tool to make parts directly. After making them, they would take out calipers from time to time to mark them and continue the discussion.

It was not until noon the next day that the two put down the drawings in their hands and marked out the deduced data directly.

The two of them then put down their pens and looked at each other.

"Oh, it's still more comfortable to study here. We can check for omissions and make up for deficiencies at any time during on-site production." One of them said, and the other one also laughed.

Today's research was the most comfortable and smoothest. There was no need to discuss applications, make applications, or wait in line for the machine. It was simply too smooth!

There are machines available at any time to verify the dimensions and then check the theoretical air tightness based on the actual dimensions.

"Comrade, let's make one first and see the effect."

The two designers said after looking at the final drawings.

"According to our design, if it is made of our materials, the service life will be reduced by 1/3, and the power will also be slightly reduced accordingly, but the stability and penetration of the bullet will be slightly stronger than before.

If we can get high-density steel to make a part inside that connects the barrel and bullet, these effects will be minimized."

After hearing this, Jia Dongxu suddenly thought of the material ratio that the metallurgical plant was researching. "Brother Wang, how is the research and development of special steels at the smelter going? I wonder if those special steels can be used?"

One of them listened and asked with interest, "What fields are special steels used in? Is there a raw material ratio?"

Jia Dongxu thought for a moment, glanced at Wang Tongming, and then said.

"Comrade, this steel rail just used in our country's special environment is resistant to high temperatures and severe cold, and has extremely high requirements for strength and flexibility.

Because the matters involved may involve the construction of our country, I hope you can sign a confidentiality agreement. "

"No problem. It's surprising to find such a ratio in China. I think it must be very challenging."

One of them smiled and said, "This happens to be my area of ​​expertise."

The two men picked up the pens and quickly wrote the confidentiality agreement. For people like them, they were very familiar with writing these agreements.

When Jia Dongxu saw it, he signed as well. Then he looked at the others and saw Wang Tongming shaking his head. It was obvious that they had all signed.

After seeing two or three people sign, Wang Tongming nodded. Led by Jia Anguo, they escorted everyone to a secret place in the factory. There were many sentries outside.
