Chapter 176 Two Years (First update! Please vote for me!)

"This is..."

Inside the factory, the harsh sound of metal broaching echoed.

In front of a simple machine tool, a worker with sweat dripping from his forehead looked at the silver-white metal shavings brought out as the coolant flowed out.

Driven by the motor, the broach slowly retreats, while the cylindrical workpiece rotates slowly.

Amidst the harsh broaching sound, the coolant flowing from the hose into the workpiece slowly flowed, and the silvery-white metal shavings and coolant reflected the light.

"Wow..."

After completing the wire pull, Li Jiehui immediately loosened the clamping wheel and re-fixed the workpiece according to the positioning. After a while, the harsh sound of broaching sounded in his ears again.

"Wire pulling machine..."

When the machine started working, Li Jiehui couldn't help but laugh as he stared at the machine in front of him, which was probably the crudest and roughest machine tool in the entire factory.

This wire drawing machine is his homemade equipment and brought him a bonus of 1,000 yuan two months ago. The wire drawing machine is the most important equipment used to make the rifling of the gun barrel. The rifling is the soul of the barrel. Without rifling, the bullet

It is almost impossible to hit the ball far and accurately.

Although there are thousands of advanced machinery and equipment purchased from Germany, the United States and other countries in the Erqing Factory, most of them are civilian equipment and there is no wire drawing machine at all. A month ago, the factory offered a reward of 1,000 yuan.

, offering a reward for solving the problem of rifling manufacturing, Li Jiehui just took a look at it, and then began to silently build the wire drawing machine.

Twenty years ago, when Li Jiehui was fifteen years old, he entered the Beiyang Manufacturing Bureau in Tianjin, where he and his master made wire drawing machines. Later, more than ten years ago, the Eight-Power Allied Forces burned down the Beiyang Manufacturing Bureau.

, he then moved to the Dagu Shipyard. After working in the shipyard for more than ten years, he had long forgotten about the Beiyang Manufacturing Bureau.

In the past ten years, Dagu Shipyard has been in a difficult situation. It has not built a single ship for many years, and there are only a few ship repair jobs. From the glass hall to the workshops, it is deserted and lifeless. The monthly salary of employees and workers is difficult to maintain.

This reason can be traced back to the Sino-Japanese War of Sino-Japanese War and the Battle of the Yellow Sea, which caused the Beiyang Navy, which had spent a lot of money to set up, to be completely defeated. The war reparations that followed severely damaged China's vitality. All industries were in ruins, the market was depressed, and the people were in dire straits. Naturally,

No one built any warships.

After the Republic of China, the monthly salary of the workers at the Dagu Shipyard was even more difficult to maintain. It was for this reason that Li Jiehui came to Lianyungang. He only entered the second light industry because he had worked in the Beiyang Manufacturing Bureau for several years.

Machinery factory.

He built this simple wire drawing machine half a month ago. In fact, the wire drawing machine is not complicated. At least for Li Jiehui, this wire drawing machine is just a "carpentry job", and the first wire drawing machine

The spool and most components are also made of wood.

It was not until the wire drawing machine made of wood was used to manually pull out the rifling that the factory used the wire drawing machine made by Li Jiehui as a prototype to create a new type of wire drawing machine. Although it was also very crude, it produced rifling without any problems.

After removing the rifled barrel from the wire drawing machine and placing it on the stand, Li Jiehui saw that the barrel had been taken away. When he turned around, he saw that it was Mo Fan, the technical associate manager of the factory.

"Associate Mo"

When Li Jiehui said hello, Mo Fan had already raised the barrel of the gun and checked the light bulb. After turning the barrel of the gun to check, Mo Fan smiled.

"Lao Li, the rifling is well done."

Looking at Lao Li, Mo Fan finally understood why the company values ​​workers. Sometimes many old workers are more useful than their technicians. At least this simple wire drawing machine can be used by itself.

, I’m afraid it really can’t be made.

"It's just a little slow. To process six riflings, you need to change the broach four times, which takes more than ten minutes. If..."

Hesitantly, Li Jiehui pointed at the broach and put forward his own idea.

"I was wondering if this could be possible,"

As he spoke, he started gesticulating.

"...It is to add three sets of broaches behind the broaches. Just like this, the drawing depth of each set of broaches is different, from shallow to deep. The tapping broaches are changed from single blade to four or six blades.

Blades, like this kind of gun barrel, use a six-blade broach with four sets of six blades. One gun barrel can be processed at one time, so the work efficiency can be increased by at least twenty times."

Li Jiehui's words made Mo Fan think deeply. He half-closed his eyes and thought about it. This was indeed a good suggestion.

"Well, this is a good idea. Let's do it tomorrow..."

"Associate Mo,"

Suddenly, Mo Fan was interrupted by someone. It was Director Liu, and he was seen running over in a hurry.

"The chairman is here. He is at the shooting range and wants you to come over."

The chairman is here? At the shooting range?

"Da, da..."

The crisp sound of gunfire echoed in the shooting range. According to the 2008-year-old submachine gun, the butt of the gun was pressed against his shoulder. Li Zicheng squeezed the trigger from time to time. Accompanied by the sound of the gun, the brass cartridge cases continued to pop out of the gun chamber. With the continuous pull of the gun, Li Zicheng

When you turn the trigger, the sound of the gun will change from time to time, which is the unique sound that MP40 periodically produces.

"This gun is good"

After emptying one magazine, Li Zicheng put down the gun in his hand and smiled with satisfaction.

Looking at the MP40 in his hand, no, it should be a Type II submachine gun. Li Zicheng couldn't help but think of scenes from old movies. German soldiers holding MP40s one after another. In many people's minds, the image of a German soldier is roughly

Two characteristics: wearing a German-style steel helmet and holding an MP40 submachine gun. But now, in this time and space, the MP40 appears in China as a Type II submachine gun, appearing in China in 1913

The reason why submachine guns were chosen was all due to the need to "prevent bandits". In the future, Henan and Shaanxi along the Longhai Railway will be infested by bandits. There will only be a few road police accompanying the trains to escort them, so they need a weapon with powerful firepower.

Machine guns are inconvenient, only submachine guns with powerful firepower are most suitable.

"Ping Nan, do you want to try it?".

He casually threw the submachine gun into Yan Pingnan's hand. When he was shooting targets earlier, Yan Pingnan looked eager to try, and Li Zicheng smiled.

“Okay”

Taking it, he skillfully pulled out the magazine, and Yan Pingnan loaded the magazine with bullets.

"Master, this gun..."

When loading bullets, Yan Pingnan realized that this kind of magazine was far less useful than the carbine magazine.

“It’s very difficult to load bullets in this magazine.”

"oh?"

Surprised, he took the magazine and took a look in his hand. Li Zicheng immediately understood the reason. This was a double-row single-feed magazine, and loading was very laborious.

"Kang Ping,"

He turned around and looked at Liu Kangping, who was standing next to him. He was the director of the Second Light Factory and studied military manufacturing in Japan.

"Who is the designer of this gun?"

"The chairman is Mo Fan"

Liu Kangping quickly replied, while looking at the magazine with some surprise. This magazine is inconvenient? Is there any more convenient magazine?

"Let him come here"

After giving the order, Li Zicheng turned to look at Yan Pingnan, who was trying his best to load the magazine.

"Pingnan, are you carrying a gun in the car?".

The gun refers to the M4 carbine made by Bushmaster. Now all his personal bodyguards carry this powerful automatic weapon with them.

"Bring it, young master..."

"Go get the magazine."

A few minutes later, Mo Fan stood in the shooting range and looked at the two magazines in his hands. The two magazines, one long and one short, seemed to have no difference. The biggest difference was that the Type II submachine gun he had made

The top of the magazine is pointed and can only hold one bullet, while the other wide magazine has an even opening.

"Do you see the difference between these two magazines?".

Seeing that he had been making gestures for a while, Li Zicheng asked with a smile.

Shaking his head, Mo Fan really didn't see any essential difference between the two magazines.

"The magazine of the Type II submachine gun is a double-row single-feed magazine, and this..."

Pointing to the 4179 magazine in his hand, Li Zicheng smiled.

"Double-row double-feed magazine, compared with the former, its ammunition supply is more stable..."

With that said, Li Zicheng took the test report of the Type II submachine gun from the gun table and turned to one of the pages.

"... After testing 3,000 rounds of ammunition, ammunition supply failure occurred 13 times. After inspection, it was found to be caused by the magazine..."

When I didn't know about the MP40 in the past, I thought it was a perfect weapon. However, when I read this test report, I found that the MP40 was far from perfect as I imagined, at least the magazine was not perfect.

"Chairman, what do you mean?"

Holding these two magazines, Mo Fan guessed the chairman's plan.

"Should we refer to this magazine to redesign the magazine of the Type II submachine gun?"

Li Zicheng nodded with satisfaction, looked at Mo Fan, and asked with a smile.

"How, can it be done?".

In fact, although the Second Light Factory has now produced the MP40 and has even begun trial production of the mg42 machine gun, the Second Light Factory does not have any design capabilities at all. It has even encountered problems of this kind when manufacturing weapons according to drawings. After all, firearms production
