Siheyuan starts from a good life

"Gong Jiang, this is a combined machine tool for primer processing. These machine tools are also the highest precision machine tools. These machine tools are the machine tools from Hans that were purchased in SL at that time. They were assembled by our engineers. Now we It’s a treasure in the factory! It’s because of it that our production efficiency will be doubled.”

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

It turns out that assembling a finished bullet is mainly divided into two parts, with the cartridge case as the main part, namely the processing of the primer and the bullet assembly (assembly of the cartridge case and 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 China, our country has used high-precision combined machine tools to process primers to reduce manual operations as much as possible to improve production efficiency and safety.

"That's right! You need to check and pick out the inappropriate ones before you can move on to the next step."

"This still needs to be checked!"

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

After installing the primer, the machine tool also applies sealing paint between the primer and the cartridge case to prevent the primer from getting wet and causing the bullet to fail.

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

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

I have to say that the generosity of the Northeastern people is vividly displayed in Hao Pingchuan's daughter-in-law Yang Xiaomei. Every time he goes to his home, he will prepare a lot of Northeastern specialties to entertain Jiang Yan and the others.

After Hu Dahai said this, he explained: "Female workers are more attentive than male workers, so they basically use female workers to check whether the ground fire is installed properly."

In the past two months, Jiang Yan and his workers began to repair other machines. With the help of his space computer, Jiang Yan restored several machines. The drawings of these machines were quickly studied by dedicated personnel. Experimental production began at Fengtian No. 1 Machinery Factory. As a reverse imitation engineer, Jiang Yan was also called over to guide the work several times. Under Jiang Yan's guidance, the first batch of machine tools was successfully produced by Fengtian No. 1 Machinery Factory. Soon these machine tools were shipped across the country, which greatly alleviated the shortage of machines in the factory.

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

Hu Dahai also said with emotion.

After hearing what Hu Dahai said, Jiang Yan looked at the busy workers and said, "There will be a day."

This machine tool has been widely used in later generations and has a wide range of uses. It can be used for rough machining and finishing of mechanical parts. It has a reliable structure, easy operation, economical and practical. The control system has complete functions and high reliability. This machine tool can meet the needs of many industries, such as automobiles, tractors, military industry, machinery and other industries. The machine tool is particularly suitable for efficient and high-volume turning processing of internal and external cylindrical surfaces, taper surfaces, threads, drilling, reaming and curved rotary bodies of shafts and disk parts.

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

If you ask Jiang Yan whether he mixed in some private goods, the answer must be yes. How can he be worthy of his status as a time traveler if he doesn't mix in some private goods?

This was the first machine tool that later Jiang Yan came into contact with. He had dismantled this machine tool countless times when he was in school. Jiang Yan was so familiar with the structure inside that he could draw its structural diagram with his eyes closed.

"Yes! Boss, today is an eye-opener for me. It's so shocking." Xu Damao said next to him.

After listening to Hu Dahai's explanation, the inspector nodded and said nothing. However, Xu Damao next to him looked at the female workers at work with interest, and Jiang Yan gave him a kick in anger.

The most important thing is that according to the current production level of the country, Fengtian No. 1 Machine Tool Factory is fully capable of producing this machine tool. Originally, this machine tool was the product it was responsible for developing. Jiang Yan gave this machine tool to They are the return of things to their original owners in disguise.

However, the weather in this Ice City in July is much better than that in Forty-Nine City. Although it has entered summer, the weather here is still the same as the weather in April and May, very refreshing.

After that, the bullet enters the assembly line, and a professional bomb assembly machine tool first pours the weighed propellant into the cartridge case, and finally squeezes the warhead into it. After weighing inspection and appearance inspection, a qualified bullet is born.

"Oh, they're wearing insulating paint."

Through Hu Dahai's explanation, we found that before the warhead is officially loaded into the cartridge case, the machine tool will apply a layer of sealing paint on the mouth of the cartridge case. Since metal processing will produce certain errors after all, it is difficult to ensure that each cartridge case and warhead fit perfectly. Therefore, applying sealant paint can completely isolate the air inside and outside and prevent the gunpowder inside the cartridge case from getting damp and affecting the performance of the bullet.

Among the drawings for the imitation machine tools, Jiang Yan also sent them the drawings of the CA74 lathe developed by Fengtian No. 6140 Machine Tool Factory in .

Seeing some female workers checking the bullet casings that had been installed with ground fire, Jiang Yan asked curiously.

Jiang Yan pointed at the workers painting the connection between the bullet casing and the bullet and asked curiously.

"But all the machines here are made abroad. I don't know when we will be able to use our own machines to produce bullets."

When people are busy, time seems to fly very fast. After visiting the bullet production, two months have passed unknowingly. At this time, it is already July, and the weather is gradually getting hotter.

Everyone has a limited amount of meat tickets each month. Even Hao Pingchuan, the police chief, probably doesn't have much. Jiang Yan was also curious about why Hao Pingchuan had so much meat at home. Through Yang Xiaomei's explanation, Jiang Yan understood that Yang Xiaomei His father is an old hunter, and his marksmanship is really superb. In this era, there are a lot of prey in the forests of Northeast China. Every time he goes into the mountains, he will come back with a full load. Most of the prey is sold to the supply and marketing cooperative, and the rest becomes the talk of his family. There was food in the house. Yang Xiaomei was the only girl in their family, so she was naturally favored and given more food.

Northeastern people like to drink. How can we miss out on wine at every gathering? Jiang Yan found that Yang Xiaomei’s drinking capacity was not much worse than the two of them. However, a loser was still a loser. Xu Damao still maintained the record of drinking in just a few ounces. , according to Yang Xiaomei, for Xu Damao's drinking capacity, his fate is to end up on the children's table.
