"Oh! That's good! That's good! Yang Chong listened to Mu Chun's explanation and praised loudly. Pen & Fun & Pavilion www.biquge.info

Although he didn't know what deep-drawn high-quality carbon steel was, he didn't know what it was when he heard the long list of names.

Now that Daming can produce it, it is indeed gratifying.

So he continued: "According to what you say, is the problem of our Daming bullet solved?" ”。

But who knows, Mu Chun shook his head and sighed: "Hey! This is just the first step. The warhead also needs to be assembled. ”。

Saying that, the professional 'karmic illness has been committed again! began to talk endlessly about the warhead assembly process.

According to the process, the bullet core is pressed into the → tail cone part pre-pressing→ bottom curling→ tail cone part forming→ passing diameter → roller groove → size comparison→ weighing → appearance selection.

Among them, the tail cone preload is to press the bullet core into the cylindrical part behind the warhead shell to make it press into a tail cone of a certain length. Create conditions for the shaping of the bottom crimp and the tail cone.

And in order to ensure the coaxiality of the warhead tail cone and the cylindrical part of the warhead, the head of the warhead is generally pushed with a punch, so that it enters the tail cone die for the tail cone.

In this case, the warhead must be turned 180 degrees after the final pressure process before it can be fed into the finishing cone process. When entering the tail curling process, it is necessary to turn 180 degrees.

When the tail cone is formed, the tail cone and the bottom socket of the missile after the curl are also finally formed.

The equipment used is a multi-station automatic punching machine.

Then there is the final process of warhead processing: tumbling → size contest→ weight contest → appearance inspection.

The purpose of rolling is to remove the oil stain and oxide film on the surface of the warhead, so that the surface of the warhead is clean and bright, which is convenient for inspection and full bomb assembly. A rolling machine is used.

The size contest is to conduct a 100% inspection of the length of the warhead, including the diameter, diameter of the roller groove, height, tail cone size and other items. In general, as long as the machine and mold are properly adjusted, these dimensions are not prone to problems.

However, the length of the warhead will accumulate into a deviation due to manufacturing errors, so it must be 100% inspected.

The equipment used is a size weighing machine.

Weight contest: Use a weighing machine to remove overly light and overweight warheads, and classify qualified warheads by weight. Then send it to the assembly workshop for assembly.

The last process, the appearance inspection!

This is the most labor-intensive process in the warhead production process.

Because the surface of the warhead will have defects such as line marks, wrinkles, rust, oil stains, guidance, crushing of the bottom of the bullet, and incomplete roller grooves, etc., and cannot be identified by machine tools, it can only be selected by visual inspection.

This step can only be completed by the appearance inspector with manual operation.

At this point, the warhead processing is really completed. In later generations, even qualified warheads will be subject to comprehensive quality sampling.

This shows the complexity and rigor of the production of guns and ammunition.

Immediately after that, it is the assembly of the bombs.

This is the last link in the production process of guns and bullets, and it is also an important process that ultimately determines the quality of guns and bullets.

Because it involves pyrotechnics and ******, a slight negligence can cause a large number of waste products or major safety accidents.

So much so at this stage, special attention is paid to quality and safety.

Daming's imitation of the domestic Type 56 rifle ordinary bullet, the parameter is 7.62×39mm. In the assembly process, there are two steps.

The first is priming, calibration, dispensing and inner coating.

The second is the loading of fire, projectile, and medicine, and the warhead and the tight mouth of the warhead.

Finally, the calibration, inspection, sealing and selection of bullets.

Of course, this also requires a combination of assembly machines.

Yang Chong, who was in the fog, actually didn't listen to a word in his heart.

But his mind was filled with another question.

So he looked at Mu Chun squarely and said suspiciously; "As far as I know, you weren't from a steel mill? How do you know what to do with this bullet? ”。

Although Mu Chun has always been in charge of the arsenal, this detail is too clear. Like this machine, that machine, all poured out like a treasure.

Let those who don't know think that Mu Chun came out of the bomb medicine factory.

Hearing this, Mu Chun laughed awkwardly a few times, and explained embarrassedly: "That--that, of course I can't know so clearly." But in the factory, aren't there insiders? ”。

As he spoke, Mu Chun invited the only technical expert in the factory.

This is an old man with gray hair, but a tough body and good mental energy.

His name is Chen Guoguang. Volunteers who participated in the War of Resistance against the United States, Aid Korea, and Korea. Later, when he returned to China, he was assigned to the arsenal. From a primary school apprentice, he slowly became a technical expert.

In the Ming Dynasty, it is about experience and experience. He said first, and no one dared to say second.

Like the very beginning of the local method of making bombs, it was this old man himself who instructed and directed. Help Daming through the most difficult and difficult period.

If it weren't for his age, he would have been able to go into battle in person. Like now, I can only be an idle technical instructor.

On the day of the Dragon Boat Festival, after retirement, he and his wife took their granddaughter and took a car to the south. Prepare to go to Shanghai and spend a reunion Dragon Boat Festival with my son and daughter-in-law.

But it didn't come to pass, so heaven and man are forever separated.

Fortunately, he is a man who has experienced strong winds and waves and crawled out of the pile of dead people. 's tenacious character made him reach the Ming Dynasty, and he didn't show much hope.

And in the arsenal where there is a shortage of talents, he has found his own value. Life is full of energy and energy!

The people who grew up in that era were roots, positive, seedlings, and red, and their thoughts were relatively pure and pure. He stayed in the arsenal and never relied on the old to sell the old. In terms of dealing with people, he is also more amiable and friendly. If others have technical questions that they don't understand, he will answer them patiently.

So the people in the entire arsenal respected him more.

Including Mu Chun, he never called himself a minister in front of him, only a junior.

Yang Chong also knows these things.

In fact, he still wants to pay a good visit to this old man, but he is always unavailable. I came to the arsenal several times, but I never met anyone.

I was really lucky to run into it today!

Therefore, without waiting for Old Man Chen to approach, he took the initiative to greet him. Pulling the old man, he asked with concern: "Old man, are you going to live a long life this year?" ”。

This scene was instantly filmed by the accompanying reporters.

It is estimated that tomorrow's newspaper broadcast will be another report by Yang Chong and the people.

"I-I-I'm sixty-seventy!" , Old Man Chen replied movingly, his voice was a little choked.

Although the Ming Dynasty is no longer the red, color, and Chinese country of later generations, Yang Chong was just a train driver at the beginning.

But in the end, Daming inherited the mantle of Huaxia, and Yang Chong was also the president of Daming.

Such a high-ranking person, so respectful of him, an old man. This kind of mood is like that of later generations of national leaders and leaders, who went to the countryside to see the common people.

That excitement, that emotion, is genuine.
