The madman looked at Xiao Chen as if he had seen a ghost.
With his character, he probably wouldn't be so surprised even if he really saw a ghost.
"But this is already amazing." Xiao Chen thought that the madman was unhappy, so he quickly added, "With the existing technology and materials, you can produce such a precise gun. Brother Madman, you are definitely a veritable miraculous craftsman."
"Do you think it could be better?" The madman's words were not a show of force, but came from his heart.
"Of course. First of all, it is best to stamp the gun barrel with fine steel and form it in one piece. There is no need to roll other alloys inside..." Xiao Chen sat down and picked up a straw stick and drew a gun barrel on the sand.
Son.
"It's not difficult to cast fine steel in one piece, but how do you draw the rifling inside? Or do you mean we don't need rifling?" The madman also sat down opposite him and questioned.
Fine steel is already the hardest material at present. If you want to cut rifling into it, it is simply impossible to do.
"Of course there must be rifling, otherwise the projectile cannot rotate in a straight line, and the accuracy and range will be greatly affected. For example, in today's muskets, the amount of gunpowder must be increased to increase the range, otherwise it will not be able to shoot far... Rifling is still
There is a way to do it, it’s called die extrusion..."
Xiao Chen drew a drawing mold similar to a drill bit while talking. Everyone came over out of curiosity, but no one except the madman could understand what this thing was.
The die extrusion method is also called the top drawing method, which is a rifling manufacturing process that was only developed in the 20th century.
The specific method is to first make a solid gun barrel, drill a smaller hole in one end, and then use a high-hardness drill bit with protrusions corresponding to the bore line to drill down from the hole with a high-pressure machine to remove the steel.
Extruded into yin and yang rifling.
There is no problem in theory, but first of all, how do you make a drill bit that is harder than fine steel? Secondly, how much pressure does it require?
Unless you move a small mountain of rocks, you have to turn it, and the speed of rotation must be fast enough...
"So if you want to make this kind of gun barrel, you need to make a stamping machine first. There is no electricity at the moment... But we can use water power and some gears to do it. This is quite complicated. I won't draw it now.
As for drill bits, alloys can be used. Of course, this also requires a high-temperature casting furnace..."
Xiao Chen spoke seriously, and Madman listened carefully. The two of them were completely immersed in science and could not extricate themselves.
As long as the casting process is improved, the gun barrel can also be cast with alloy, reducing its rigidity and increasing its plasticity during the casting process.
The drill bit is made of the hardest material, and coupled with the theoretically highest speed that can be achieved, rifling can be completed.
With perfect rifling, lead bullets can also be made with a copper core, so that the weight of the projectile can be reduced a lot, the range and lethality can be greatly improved, and the amount of gunpowder used can also be greatly reduced.
Xiao Chen also came up with an idea that sounded extremely magical to a madman, which was to use something called a cartridge case to launch projectiles.
A certain amount of gunpowder is added to the cartridge case, and some relatively sensitive ignition is compacted at the bottom, and a firing pin is installed behind the barrel of the gun.
In this way, as long as the firing pin hits the rear of the cartridge case, it will ignite the primer, which will then detonate the gunpowder, and the powerful impact force will push the projectile out.
This is completely the prototype of the structure of modern guns, spanning several centuries of gun technology revolution.
From the oldest muzzle-loading gun, which required a rod to press the gunpowder, we passed over the flintlock gun and went directly to the most advanced technology.
The madman couldn't accept it for a while.
"Of course, this can't be done in a year or two. We don't have such fine craftsmanship now. This is just my whim." Xiao Chen sighed. What he said was all theory. In fact, with the current
At the industrial level, we are still far from being able to do this.
But being able to come up with such a theory is already very, very remarkable. At least to the lunatic, Master Xiao Chenxiao is a god-like existence!
From now on, I, the madman, will follow you!
I don't want anything, as long as you can chat with me for a while when you have nothing to do, I'll be satisfied.
It is said that if you look at the whole world, there is only one person in the world who can make a lunatic admire him wholeheartedly and worship him as a god-like idol.
This is the power of science!
Lu Fei brought two large cars, and Wen Shanchang also came with him. He first checked Duan Ling'er's injury, and found that it was not serious.
But after seeing Fu Yan's wound, he couldn't help but stick out his tongue. My dear fellow, you are so awesome. You are running thousands of miles with such a fatal wound?
It's a medical miracle that you didn't die, but you lost too much blood along the way, and all the organs in your body are beginning to show signs of failure. According to common sense, you will still die...
You are lucky enough to meet me, I hope you are lucky!
He opened the medicine box, washed his wounds with medicinal wine, cut out the rotten flesh, and sutured it directly with needle and thread. Because Fu Yan's body organs were already quite fragile, he did not dare to use anesthesia.
Just ask Fu Yan to be patient.
And Fu Yan was really a tough guy. From beginning to end, he gritted his teeth and never said a word!
Everyone admires him very much.
"Brother Fu, if the pain is severe, just scream. It will be better if you scream. We are all one of our own, what's the point of being embarrassed?" Duan Ling'er even panicked because of the pain for him.
"How about I help you find a piece of wood and bite it on the wood? It would be terrible if you accidentally bite off your tongue." Tie Kunlun found a piece of wood and tried to stuff it into Fu Yan's closed mouth.
"Oh, this is really a soft knife to cut flesh, I'm afraid it will hurt to death. If it were me, I would have cried for my father and mother. Brother Fu is really a man of iron bones!" Lu Fei gave Fu Yan a thumbs up.
.
But Fu Yan closed his eyes tightly, clenched his teeth, and said nothing...
"Stop yelling, he fainted from the pain." Wen Shanchang said slowly.
oh……
Only then did everyone suddenly realize, no wonder he remained silent.
After Fu Yan woke up, he found himself lying naked on a soft bed, and the bed was still swaying. It turned out that it was a moving cart.
There were two beautiful women beside the bed. One was wiping his body with a soft towel, while the other was boiling medicine on the charcoal brazier.
Seeing him wake up, they both showed beautiful smiles.
"Me, me, I can do it myself!" This was the first sentence Fu Yan said.
After all, it would be so embarrassing for a grown man to be naked in front of two beautiful women. The most embarrassing thing is that the beautiful woman is wiping his most unsightly part!
"Mr. Fu, please don't move. The miracle doctor said that if your wound opens again, it will be terrible!" The round-faced beauty who wiped his body quickly held him down as he tried to get up.
Quite big.
"We are nurses in the military, responsible for taking care of wounded soldiers. In fact, we are half doctors. We don't shy away from medical treatment, so you don't have to be embarrassed." The beauty with an oval face who was making medicine said with a smile.
"But..." Fu Yan's white face turned red, and he was too embarrassed to speak.
