Siheyuan starts from a better life

Chapter 263, one month
"Jiang Gong, this is the combined machine tool for primer processing. These machine tools are also the most accurate machine tools. These machine tools are the machine tools from Hans Country that were bought back in SL at that time. They were assembled by our engineers. Now they are ours. The treasure in the factory! It is because of it that our ground fire production efficiency will be doubled."

Hu Dahai pointed to several machine tools that were different from other machine tools and introduced them.

The original assembly of a finished bullet is mainly divided into two parts, mainly the shell, namely the processing of the primer and the assembly of the finished bullet (the assembly of the shell and the warhead).

The primer of each bullet is the most critical part of the bullet. If the primer is damaged during production and transportation, it is very likely to have unimaginable consequences at any time.

As early as shortly after the founding of the People's Republic of my country, high-precision combined machine tools were used in the processing of primers to reduce manual operations as much as possible to improve production efficiency and safety.

After the primer is installed, the machine tool also applies a sealant between the primer and the cartridge case to prevent the primer from getting wet and the bullet from becoming invalid.

Seeing some female workers inspecting the bullet casings that had been installed, Jiang Yan asked a little curiously.

"This still needs to be checked!"

"That's right! It needs to be checked, and those who are not suitable can be selected before entering the next link."

After Hu Dahai said this sentence, he opened his mouth to explain: "Female workers are more careful than male workers, so basically all the workers who check whether the ground fire is installed are female workers."

After listening to Hu Dahai's explanation, Inspection nodded and did not speak, but Xu Damao who was next to him looked at these female workers with great interest, and Jiang Yan kicked him angrily.

"What kind of paint is this on?"

Jiang Yan curiously pointed to the worker who painted the joint between the bullet case and the bullet and asked curiously.

"Oh, they're painted with insulating varnish."

Through Hu Dahai's explanation and inspection, it turns out that before the warhead is officially loaded into the shell case, the machine tool will apply a layer of sealing paint to the mouth of the shell case.After all, there will be certain errors in metal processing, and it is difficult to ensure the tight fit between each shell and bullet. Therefore, the sealing paint can completely isolate the internal and external air, and prevent the gunpowder inside the shell from being affected by moisture and affecting the performance of the bullet.

Afterwards, the bullets enter the assembly line. The professional bullet-making assembly machine first pours the weighed propellant into the shell, and finally squeezes the bullet into it. After weighing inspection and appearance inspection, a qualified bullet is born.

"It turns out that there are so many processes in the production of bullets! I thought it was too simple before." Jiang Yan sighed while holding a manufactured bullet.

"That's right! Boss, I also had an eye-opener today, it was too shocking," said Xu Damao next to him.

"However, the machines here are all made abroad, and I don't know when I can use my own machines to produce bullets."

Hu Dahai also said something with emotion.

Hearing Hu Dahai's words, Jiang Yan looked at the busy workers and said, "There will be such a day."

Hu Dahai also murmured to himself when he heard Jiang Yan's words: "Yes! There will be such a day."

When people are busy, it seems that time flies very fast. It has been two months since the production of bullets after visiting. At this time, it has come to July, and the weather is gradually getting hotter.

However, the weather in July in the Bingcheng City is much better than that in Sijiu City. Although it has entered summer, the weather here is still as refreshing as the weather in April and May.

During these two months, Jiang Yan led the workers to start repairing other machines. With the help of his space computer, Jiang Yan recovered several machines. The drawings of these machines were quickly studied by special personnel. Experimental production started at Fengtian No. [-] Machinery Factory. Jiang Yan, as a reverse imitation engineer, was also called to guide several times. Under Jiang Yan's guidance, the first batch of machine tools was successfully produced by Fengtian No. [-] Machinery Factory. Soon these machine tools were sent to the whole country, which greatly alleviated the shortage of machines in the factory.

If you ask Jiang Yan if he has any private goods, then the answer must be yes, how can he be worthy of his status as a time traveler without some private goods.

Jiang Yan also sent the drawings of the CA74 lathe developed by Fengtian No. 6140 Machine Tool Factory in [-] in the drawings of those imitated machine tools.

CA6140 is a horizontal lathe improved on the basis of the original C620 ordinary machine tool. In the name of the machine tool, C stands for lathe and A is the structural characteristic code to distinguish C6140. 6 stands for horizontal, 1 stands for basic type, and 40 stands for The maximum rotation diameter is 400MM, which is one of the equipment required by machinery and equipment manufacturing enterprises.

The CA6140 lathe has a complex structure and wide performance, and is suitable for processing various rotating parts. Its tool holder can tighten four different turning tools at the same time. Under different working conditions, four different turning tools can be used alternately by rotating the tool holder. The workpiece is processed.

This machine tool is widely used in later generations and has a wide range of uses. It can be used for rough machining and finishing machining of mechanical parts. It has a reliable structure, convenient operation, and is economical and practical.The control system has complete functions and high reliability.The machine tool can meet the needs of many industries, such as: automobiles, tractors, military industry, machinery and other industries.The machine tool is especially suitable for high-efficiency and large-scale turning processing of inner and outer cylindrical surfaces, taper surfaces, threads, drilling, reaming and curved rotary bodies of shaft and disk parts.

It was the first machine tool Jiang Yan came into contact with later. He had disassembled this machine tool countless times when he was in school. Jiang Yan was too familiar with the structure inside, and could draw its structure diagram with his eyes closed.

The most important thing is that according to the current national production level, Fengtian No. [-] Machine Tool Factory is fully capable of producing this machine tool. Originally, this machine tool was the product it was responsible for developing. They are also the original owners in disguise.

During these two months, every Sunday, Jiang Yan either went to Hao Pingchuan's house, or Hao Pingchuan came to the factory to pick up Jiang Yan. In order to facilitate Hao Pingchuan's entry and exit, Jiang Yan specially helped him apply for a special pass.

It has to be said that the boldness of this Northeast person is fully displayed in Hao Pingchuan's daughter-in-law Yang Xiaomei. Every time he goes to his house, he will prepare a lot of Northeast-style meals to entertain Jiang Yan and the others.

Everyone has a limited amount of meat tickets per month. Even Hao Pingchuan, the police chief, probably doesn't have many. Jiang Yan is also very curious about why Hao Pingchuan's family has so much meat. Through Yang Xiaomei's explanation, Jiang Yan understands that this Yang Xiaomei His father is an old hunter, and his one-handed marksmanship is really superb. In this era, there are a lot of prey in the forests in the Northeast. Every time he goes into the mountains, he will return with a full load. Most of the prey are sold to the supply and marketing cooperatives, and the rest become the mouths of his family. Yang Xiaomei was the only girl in their family, so she was favored a little, and she gave away more things.

Northeast people like to drink, how can they get less alcohol at every party, Jiang Yan found that Yang Xiaomei's drinking capacity is not much worse than the two of them, but waste wood is still waste material, Xu Damao still maintains the record of drinking in twos and twos According to Yang Xiaomei, with Xu Damao's drinking capacity, on their side, he would be a child's life.
