- "This speed is really fast!"
"Yes, if we build it separately, it will take half a month to see the finished product. Now, it's just the first day, and we have already assembled a rifle!"
"That's right, the most complicated thing is to make gun barrels. Let's set up another device, so that at least four gun barrels can be ground out a day, and we can make hundreds of guns in a month!"
As night fell, on the hillside near Huangya Cave, everyone was discussing excitedly, holding the newly assembled rifle, their mouths closed in excitement.
This efficiency is unbelievable!
As long as they are manufactured according to standardized parts, in this way, the devices made by individuals can be combined into a rifle.
Today, they mainly made tools in the morning, and only started in the afternoon. As a result, in the evening, they had already made the first one.
This is efficiency.
The most complicated thing is to make the barrel, and the most convenient part is the parts that can be processed on a lathe, which is very fast!
Now, looking at this newly built rifle, everyone is quite happy.
After being processed, the surface of the track steel has a crystal clear metallic luster. The wooden gun stock has not been painted, and it still shows the original color of the wood. This gun is now placed in front of everyone. The joy in everyone's heart can be imagined.
At this moment, footsteps came from outside, and Qin Baoshan's figure appeared at the door!
"Baoshan, you are back. Come and see the rifle we made." After Qin Baoshan went out, Liu Daquan became the person in charge. It was built tonight. Everyone is very happy. Now, Liu Daquan Towards Qin Baoshan, he introduced him.
"Well, so fast?" Qin Baoshan's face was also happy, and then he put the gun in his hand, feeling heavy.
The little devil's track steel has become our steel gun!
"Is the gun barrel going well?" Qin Baoshan asked.
At this time, what he cares most about is of course the manufacture of the barrel. Other parts are easy to say, it is the barrel, and the speed of barrel manufacture directly determines the speed of gun manufacturing.
Today, the big guys put all their strength together and finally made the first one. In the future, as the technology is proficient, it will definitely be faster.
"It's okay, this method is very effective." Liu Daquan said, "However, I think we still have room for improvement, but we haven't figured out how to improve it yet."
Improve?
The power of the masses is inexhaustible. Qin Baoshan led the way and thought of the method of drilling gun barrels with the native method. However, there is still a lot of room for improvement in this method.
Although Qin Baoshan is already thinking about how to get a drilling machine from the devil, but if he can have one, it is obviously a better way.
How can I improve myself?
"We rotate the drill bit and fix the iron rod. This is the simplest method. However, the iron rod is heavy and the drill bit is light." Liu Daquan said: "It always feels inappropriate."
The iron rod is what is commonly known as the blank for making the barrel, that is, the upper part of the rail that has repeatedly rubbed off the rail. Now that Liu Daquan raised this question, Qin Baoshan began to think about it.
I designed it according to the conventional thinking. For a normal drilling machine, the workpiece does not move and the drill bit rotates to drill holes. If you want to improve it, how should you design it?
Suddenly, a picture appeared in Qin Baoshan's mind: a long bench, on which the old man sat, shaking the front handle, and then the sparks flew, and the grinding wheel began to sharpen the knife.
The grinding wheel is a grinding disc, people shake it hard, and then what?
Drill and workpiece, how about switching positions?
"I thought of it." Qin Baoshan said.
"I thought about it too." Liu Daquan followed up there.
You also thought of it? Qin Baoshan smiled and said, "Master Liu, tell me."
"It's better for you to talk first."
"Sharpening scissors to sharpen a kitchen knife!"
"That's right, sharpening scissors and kitchen knives!" Both of them said.
Sure enough, the heroes saw the same thing. At this time, the two people thought of the same method, and Liu Daquan was already discussing it with great interest.
Let's set up a stone mill in front of a long bench and install a crank!
Three people are needed! Riding on a long benchsuperior!
Insert the barrel blank into the center hole of the grinding disc, and the second person uses the shoulder to push the drill bit into the center of the barrel blank!
The third person shakes the millstone and rotates rapidly, driving the barrel blank to rotate, while the drill bit in front gradually advances and enters the deep part of the barrel until it penetrates.
In this case, the efficiency should be higher than today's!
Practice brings true knowledge. Those front-line masters have the smartest brains. They can find some special methods in practice. Without machines, they can use local methods!
Of course, this is more a test of technology. If the technology is not good enough, it is estimated that the barrels produced are also waste products.
"Today is already late, we will go to inspect the gun tomorrow." Qin Baoshan said: "In our hands, the gun must be adjusted properly, and it must not be inaccurate."
After the gun is manufactured, debugging is also a technical job. If the debugging is not good, the bullet will be crooked. Qin Baoshan said, he looked inside along the barrel and looked at the rifling inside. The engraving is not bad.
Rifling is a great invention. Before there was no rifling, they were all smoothbore guns. No matter how skilled the gunmaker was, there would always be cases where the projectile would float away tens of meters away. Where did you go.
Later, an officer got inspiration from the spinning top, let the bullets spin and fly out, relying on the rotation to maintain stability, as a result, the accuracy of the rifle came up.
The rifling is rotated and engraved inside the barrel. When the bullet comes out, it has to accept the pressure of the rifling, and it will rotate accordingly.
Even if it is the same batch of weapons manufactured by the machine, each gun is unique. After recording the characteristics, you can judge which gun it is based on a fired bullet in the future. It is commonly used in a class of cases.
Now, Qin Baoshan just looked in like this, and then frowned.
"What's wrong?" Liu Daquan asked, thinking that he was not satisfied with this rifle.
"There is still a process missing." Qin Baoshan said, and began to dismantle it. Seeing him dismantling the gun three times, five times and two times, everyone was suspicious.
"What process is missing?" Liu Daquan asked.
"Anti-rust treatment." (Remember the website URL: www.hlnovel.com - Didn't finish reading? Add this book to your favoritesI'm a member and bookmarked this chapterCopy the address of this book and recommend it to your friends for pointsChapter error? Click here to report
