"According to the arrangement of his superiors, he will serve as the director of the Military Industry Bureau, responsible for military production and industrial development. He is an expert leader and much better than me." Chen Kang said with a smile.

"I understand." Yu Hua breathed out lightly and nodded in reply.

There is no doubt that the scientific research team combination of Li Qiang + Zhuang Qianding + himself + Lin Wan will explode with unprecedented power, and when Fang Yu and Zhou Yuan return from their studies...

The base area can be regarded as having a real scientific research talent team.

"One last thing I want to ask you before I leave, when can we start making bullets?" Chen Kang carefully considered his words and said what he had wanted to ask all along.

When can we start making bullets?

This ‘made’ bullet is not a reloadable bullet today, but a serious fixed-loading bullet!

Yu Hua understood the meaning of Chen Kang's words, pondered for a while, and said slowly: "Making bullets is a systematic project. From raw materials to finished products, it involves hundreds of processes. Based on the current technological level of the base, there are about two

In half a month, we will be able to meet the benchmark requirements for the production of custom-loaded ammunition."

How many processes are involved in manufacturing a 7.92mm custom-loaded ammunition?

Warhead: brass jacket material production, stamping bottomed hollow parts, jacket covering, steel core material, steel core punch, steel core and jacket assembly, sealing paint, high-precision mold calibration and processing...

Cartridge case: Brass raw material stamping, shearing, cleaning, drilling fire holes, moisture-proof paint, mold manufacturing...

Propellant: single-base propellant or double-base propellant.

Primer: ignition anvil, firing agent fulminant.

Bullet assembly: sealing paint is applied to the warhead and cartridge case, moisture-proof paint is applied to the cartridge case and primer, efficient bullet assembly equipment, weighing, quality inspection, and packaging.

This is the production process of a 7.92mm fixed-load ammunition.

Each process has corresponding technical and equipment support behind it, and each one is indispensable. Otherwise, bullets cannot be made.

And this is only to meet the baseline requirements for manufacturing fixed-load ammunition.

It's one thing to be able to make bullets, but it's another thing to be able to make good bullets.

The entire bullet production is much more difficult than firearms production. Without a basic industrial system covering chemical industry, steel, mechanical processing and energy supply, it is unrealistic to make bullets.

Today, the technological level of the base can only meet the basic requirements for manufacturing propellants and primers, but the processing technology of warheads and cartridge cases is not good enough.

Professional stamping machine tools, drawing processing equipment, cartridge case shearing machines, bullet assembly equipment... This is the necessary processing equipment for warheads and cartridge cases.

"Two and a half months... Fortunately, it's not too long. The main reason is that the army is currently very short of bullets. The average bullet per capita does not exceed 5 rounds, so I have to ask you." When Chen Kang heard the time given by Yu Hua, he felt slightly in his heart.

Song, then explained, his words full of helplessness.

Nowadays, all the troops are extremely short of ammunition. The main force has 10 rounds of ammunition per person, while the weaker troops only have 2 rounds of ammunition per person. Some newly formed troops even have as low as 0.2 rounds of ammunition per person, with an average of 5 people getting one bullet.

.

You should know that this is the total bullets per person, not the bullets per person that can be allocated in a battle.

Not to mention rifles, nearly half of the soldiers did not have guns and could only use broadswords and spears.

At this point, it is still the level of weapons and ammunition purchased from the north and transported to the base area. If it were placed after the Eastern Expedition and the Western Expedition, the ammunition reserve level would have to drop by half.

"If this is the case, in order to alleviate the urgent need, I actually have a way to make bullets now. It is to use a completely manual method and use a lathe to process a batch of special metal rods for bullet cases to solve the production of bullet cases. The principle is similar to that of a punch machine, using metal rods to align

The raw material of the cartridge case cannot be hammered twice until the shape of the cartridge case is hammered out. The steel core of the bullet is also processed with a lathe, and the brass jacket and bowl are made in the same way as the cartridge case. Finally, moisture-proof paint and sealant are applied by hand and loaded.

Propellant and primer are used to complete the bullet assembly."

Hearing these words, Yu Hua frowned slightly and almost forgot about the situation the army was facing now. After a brief thought, he thought about the indigenous method of reloading and production that he had conceived for the Eighth Route Army when he was a military fan in his previous life. After sorting out his thoughts,

He said slowly:

"Compared with large-scale industrial production, the technical requirements of this manual custom-loaded ammunition production method are almost zero. The advantage is that it allows the army or arsenal to manufacture urgently needed bullets. The disadvantages are obvious: First, the quality of the bullets is unstable and prone to jamming problems.

, Second, there are certain requirements for workers’ skills and equipment. After all, only workers with good skills can guarantee quality, and simple lathes are needed. Third, production efficiency is low and output is low.”

Bullet problem?

It doesn’t matter, I am also Doraemon in the technical field now!

"How much can the daily output of this kind of hand-loaded ammunition be produced?!" Chen Kang was undoubtedly confused when he heard the plan thrown out by Yu Hua. After half a second, he suddenly came to his senses and quickly asked the most important question.

data.

The words conveyed urgency.

Bullet quality is unstable?

Can a bullet that has been reloaded seven or eight times become unstable?

Are there certain requirements for worker skills and equipment?

There is no shortage of workers-turned-soldiers in the team. Judging from the situation, the equipment is nothing more than lathes.

Chen Kang only cares about one thing most - the output Yu Hua said is low, what is the specific data!

"Disregarding the supply of raw materials, a seven-person manual custom-loading ammunition production line can produce about 100-300 rounds per day." Yu Hua gave the daily output data and said with a smile: "The base area can currently produce standard propellants and primers, copper and

We also have steel, so the supply of raw materials is not a problem.”

Turning the steel core, hammering the jacket, hammering the cartridge case, drilling fire holes, painting, loading propellant and primer, and bullet assembly are the seven processes of the fully manual custom-loaded ammunition production line, with a minimum of one person per process.

One lathe and seven workers can meet the minimum requirements for manual custom-loaded ammunition production.

This method was inspired by the industrial production of bullets when Yu Hua was bragging to others on the forum. The core idea is that you have your industrialization, and I have my manualization. As long as I have the raw materials, I can make bullets.

It was just right, as the base area already had the ability to supply raw materials such as propellant, primer, copper, and steel.

For industrial countries, this method is thankless, but for today's base areas, for troops with about 5 bullets per capita...

What kind of bike do you want?

Anyway, in one sentence, first solve the problem of whether or not it is available, and then solve the problem of whether it is good or not.

"100 to 300 rounds, it's enough, it's completely enough, haha, this method is very suitable for us." Chen Kang's face was filled with joy, the sleepiness in his eyes dissipated again, and the joy in his heart could not be increased. He did not expect to come out to send

During one trip, Yu Hua actually found an effective solution to bullet production.

It is true that this manual custom-loaded ammunition production method has low efficiency, low output, and unstable quality defects, and is completely incomparable with industrially produced standard bullets.

But so what?

What do these flaws affect?

In terms of shortcomings, the army has long used the most reloaded bullets, which suffer from increased rifling wear, insufficient accuracy, low effective range, insufficient lethality, etc.

Compared with reloading bullets, the hand-loaded bullets proposed by Yu Hua are simply better.

The horse column is above. This is 100 to 300 rounds per day. Taking the highest number, it will be a full 9,000 rounds in a month. If rounded up, wouldn’t it be 10,000?

Seven people + one lathe = monthly production of 10,000 rounds of custom-loaded ammunition.

And seventy people + ten lathes = monthly production of 100,000 rounds of custom-loaded ammunition.

What is this concept?

Nowadays, the Red Army has 80,000 people, and 100,000 rounds of fixed-load ammunition per month means that the total number of bullets per capita in the army has increased by 1.25 rounds per month.

To be honest, Chen Kang was so happy that he was about to cry. This is a real fixed bomb...

It's not about reloading bullets again and again.

"Also, in order to adapt to the lack of electricity and improve portability, we can also build a human-powered lathe with a pedal structure similar to that of a sewing machine and add a flywheel to achieve pure human production. In this way, it can follow the military operations, and the bullet output may be reduced.

, but the scope of adaptability has been improved. After all, most areas do not have power supply conditions."

Yu Hua thought for a while, and his fast-moving mind immediately came up with an improvement plan. He smiled and said, "Just tell the professor about this method. The professor knows how to make this kind of lathe."

Similar to a sewing machine power structure + flywheel, the power of two people's feet is enough to meet the speed of the lathe for turning processing. This kind of lathe that specializes in turning elastic cores does not need to be too big, as long as it can process elastic cores with a diameter of several millimeters.

In this way, the weight of the lathe can be controlled within 50 kilograms. After being broken into its components, it can be carried by three soldiers and move with the army. It is extremely suitable for guerrilla warfare and operations behind enemy lines.

As for raw materials, one is provided by the base area, and the other is raised by oneself.

"Okay, very good. In this way, even a company-level unit can produce bullets and be self-sufficient. It is foreseeable that the plan you proposed will greatly ease the ammunition supply pressure on the army." Chen Kang heard Yu Hua's words.

The unconventional but extremely practical improvement plan made him excited and praised him repeatedly. As a military supervisor from the army, he knew very well that the human lathe proposed by Yu Hua was very practical.

Company-level troops can permanently set up a manual custom-loading ammunition production line based on human lathes, which can travel with the army during wartime and produce ammunition during leisure time, greatly alleviating the pressure on logistics and ammunition supply.

"It's just a small thought before I leave. I'm glad that my knowledge and wisdom can help the soldiers. Director Chen, just stop here. No need to send it off." Yu Hua stood there with a smile on his face and said to Chen Kang

.

Unknowingly, the two of them had arrived at the entrance from the depths of Willow Valley, and the Dodge truck was parked a few meters away.

"Mr. Yu Hua, take care along the way." Chen Kang took a deep breath, frowned, his face was solemn and solemn, his back straightened, and he saluted the young Yu Hua with a military salute.

The word "sir" is definitely not a compliment, but a word of respect.

In Chen Kang's mind, although Yu Hua is only in his early eighteenth year, he can still be called a gentleman.

"goodbye."

Yu Hua smiled, turned around and faced the Dodge truck, and then boarded the truck accompanied by Lu Junyu and three guards carrying radios.

In order to keep communication smooth and safe, the Military Industry Bureau has specially equipped a radio station, so that whether it is information exchange or emergency matters, it can be notified immediately.

"Buzz!"
