Chapter 232 The best shortcut to strengthen the Song Dynasty’s army, I chose the right one
(Please subscribe, I have been writing carefully for a long time, and I have consulted a lot of information, please subscribe)
Chen Gui started again: "I am stupid, I dare to ask Your Majesty, what is the appropriate number of riflings?"
Zhao Ji said: "There is no fixed standard for the number of riflings."
"Chen Aiqing can lead the craftsmen to try to make twenty-two lines from two rifling lines.
And test them separately to find out how many riflings this type of musket can perform best, and then it can be retained and promoted..."
"Wei Chen obeys the decree..."
At this moment, Chen Gui, the originator of the world's musket manufacturing (the first person to invent the bamboo musket), admired Zhao Guanjia's design ideas.
Previously, he developed a flintlock musket through the design drawings of Zhao Guan's family, which was hundreds of times more advanced than the bamboo musket he invented.
Now, the Zhao Guan family has designed an upgraded version of the flintlock musket. If it can be successfully developed, it will be many times more advanced than the muskets that have been developed so far!
However, Chen Gui still had some doubts in his mind. He asked bluntly:
"I am stupid and I still have something unclear. I would like to ask Your Majesty for advice."
Zhao Ji liked Chen Gui's tireless exploration spirit in firearms research very much, and said with a smile:
"Chen Aiqing, please speak."
Chen Gui asked: "When craftsmen make such a rifled barrel, how can they make it?"
Zhao Jidao: "In my dream, I received from the gods five methods of making rifle rifling.
I will tell you in detail,
One is, the scraper method..."
Chen Gui, a military technical expert who loves and is good at the invention and manufacturing of firearms, listened attentively to Zhao Guanjia's explanation...
However, even though Chen Gui is the first smart person in the world to invent the bamboo musket,
However, when he listened to Zhao Guanjia, who had some advanced scientific and technological knowledge in the 21st century, he also felt that he couldn't digest it for a while.
Chen Gui, who is forty-nine years old this year, with a solemn face and a great yearning for military science and technology knowledge, knelt down and asked:
"I am a humble minister. Can I please use a pen and paper to write down what the official said?"
Zhao Ji smiled slightly and said:
"Liang Daguan, gave Chen Aiqing pen, ink, paper, inkstone, desk and chair."
"Old slave, I obey." Liang Shicheng agreed.
He immediately led several young eunuchs around him, brought a table and placed it in front of Chen Gui. There were pens, inks, paper and inkstones on the table. Then, they brought a chair for Chen Gui.
Chen Gui was too late to sit down in front of Zhao Guan's house.
He stood in front of the table, holding a brush in his right hand, ready to listen to Zhao Guanjia's explanation and record it.
Chen Gui also had a high level of cultural knowledge. In his early years, he was a Jinshi of the Ming Dynasty in the Song Dynasty. He served successively as general officer, county magistrate, etc., and his shorthand ability was good.
After Zhao Ji saw that everything was ready for Chen Gui to make firearms, he continued:
"The number one method of making musket rifling is the 'scraper method'."
Chen Gui's pen quickly recorded Zhao Guanjia's words on the rice paper.
In order to facilitate the record keeping, Zhao Ji said slowly:
"The 'scraper method' is to use a steel rod slightly larger than the inner diameter of the musket to carve a groove on its front end and install a hard steel piece in the groove;
There are one or two protruding strips with a certain inclination angle on the steel sheet. The front end is sharpened and the height of the protrusion can be adjusted.
This device is called a 'scraper'.
Use a scraper to insert into the bore of a musket and pull it back and forth dozens of times to cut a chamber line, then adjust the position and cut another line.
Use this method to cut odd number of riflings with a single scraper.
To cut even-numbered riflings, you can use a two-way scraper.
Of course, you can also install a single scraper, or double scrapers, and three sets of knives at opposite positions, which can cut two to six rifling lines at a time.
This is all my idea. Which method is better? Chen Aiqing can make the rifling process based on the actual laboratory and weed out the fittest."
Chen Gui quickly recorded the theoretical methods given by Zhao Guanjia.
At this time, Chen Gui was so shocked that he couldn't describe it. The 'scraper method' that Zhao Guanjia mentioned to create rifling made his eyes light up...
At this time, Chen Gui's expression was extremely shocked with a smile of admiration.
Zhao Ji added: "The first method of making musket rifling is the 'hook knife broaching method'."
Chen Gui changed to a second piece of rice paper and continued recording.
Zhao Ji said: "The hook broaching method is used to make the rifling, and the tool used is a simple manual wooden machine tool."
Chen Gui recorded this, with a puzzled expression on his face.
Zhao Ji knew that Chen Gui might not understand what the word 'machine tool' meant.
He then walked up to Chen Gui, took the brush from Chen Gui's hand, and drew a structural diagram of the machine tool on the blank space of the rice paper.
I saw that the front of the machine tool was a device that could hold the gun, and the back end was a wooden armrest with a steel tie rod that could be pushed and pulled...
When Chen Gui saw the diagram of the machine tool drawn by Zhao Guanjia for him, he immediately understood.
Zhao Ji returned the brush to Chen Gui and said:
"Chen Aiqing, this is the simple wooden machine tool diagram required for the 'hook knife broaching method'. Can you clarify the confusion after seeing this diagram?"
Chen Gui was ecstatic and kept nodding his head. Just when he was about to praise Zhao Guan's family, he was interrupted by Zhao Ji:
"Since Chen Aiqing has solved the problem, please record it quickly."
"The humble minister obeys the decree."
Zhao Ji said: "The hook knife broaching method is to place the hook-shaped cutter on a steel tie rod that is slightly thinner than the diameter of the gun bore. The height of the hook-shaped scraper blade can be adjusted by adjusting the screw on the layer of the tie rod.
Each time the wooden armrest is pulled, the hook knife on the steel lever in front of it can pass through the barrel once.
When the pull rod moves a little, the barrel can rotate at a constant speed, thereby broaching a bore line with a certain twist;
After reaching the predetermined width, change the position and pull the second rifling.
According to what I was told by the gods in my dream, using this method to draw a vaginal line only requires about twenty broaching times, and it can be completed!
If you use the same method to broach the grooves about a hundred times, the grooves formed will become thinner and more precise."
After Chen Gui finished recording, Zhao Ji said again:
This chapter is not over, please click on the next page to continue reading! "The third method of making musket rifling is the 'combined ring knife broaching method'.
The principle of this method is similar to the second method, ‘hook knife broaching method’, and can even use the same machine tool;
The only difference between this method and the 'hook knife broaching method' is that it does not use a hook knife, but uses a ring-shaped knife that is combined together.
Fix multiple hard steel rings on a tie rod, and the distance between each steel ring should be equal;
Then add equidistant scrapers with the same number as the bore lines on each steel ring. Each cutter can be connected to the cutter on the next ring along its winding angle. From the beginning to the end, it can be regarded as a spiral.
shape line.
The protrusion of the blade on each ring is slightly larger than that of the previous ring, forming a series of cutters. The grooves opened have stable width, depth and spacing. This combination of ring broaches can be cut through the gun bore once.
All the cavities can shorten the construction period and improve production and quality."
After Zhao Ji slowly finished speaking this method, he saw that Chen Gui had also finished recording it. However, it was obvious that Chen Gui was still immersed in the unfathomable meaning and could not extricate himself.
Zhao Ji said: "I drew the design drawing of the 'combination ring knife broaching method' for Chen Aiqing."
Chen Gui immediately leaned forward, holding the brush in both hands, and handed it to Zhao Guan's house.
Zhao Ji took the pen and drew a schematic diagram of the 'combination ring knife broaching method' on the blank space of the rice paper written by Chen Gui.
After Chen Gui saw the picture, he suddenly realized that it was like opening the door to a new world...
Next, in order to make the firearms maker Chen Gui understand, Zhao Ji took a smooth wooden stick from the imperial guards.
Zhao Ji drew out his sword and made several sword marks lengthwise on the smooth wooden stick...
Everyone present could not understand why the Zhao Guan family did such an unusual thing.
Zhao Ji took the wooden root with several sword marks along the length, handed it to Chen Gui, and asked:
"Chen Aiqing, do you know why I am doing this?"
Chen Gui frowned, thought for a moment, and truthfully stated what he had guessed in his mind:
"Wei Chen dared to guess the holy will. Your Majesty's move should be to explain to Wei Chen the fourth method of making musket rifling.
However, I am so stupid that I can’t even guess what the purpose of this wooden stick with several sword marks is, even if I try my best.”
Zhao Ji smiled slightly and said, "Chen Aiqing, what if this wooden stick was replaced with a hard steel top cone?"
Chen Gui, the originator of musket manufacturing, suddenly realized:
"Could it be that the fourth method of making musket rifling is to use a hard stainless steel top cone with grooves and raised vertical channels to force Yin and Yang rifling into the barrel?"
Zhao Ji nodded approvingly, admiring Chen Gui in front of him, who was hailed by later generations as the "Military Technologist of the Song Dynasty".
Sure enough, it’s easy!
Zhao Ji smiled and explained in detail:
"The fourth method of making musket rifling is called the 'rifling top cone squeeze method'."
"That is, when a hard top cone whose middle section has the same cross-sectional shape as the inner cross-section of the rifle is used to pass through the smooth bore of a barrel with an inner diameter slightly smaller than the top cone,
Under the strong pressure of the top cone, the barrel metal will slightly increase the inner diameter of the gun bore.
At the same time, the protruding part on the surface of the top cone squeezes through the inner wall of the gun chamber, causing it to deform and obtain the bore line.
At the same time, the recessed part of the top cone squeezes along the inner wall of the gun bore, causing deformation and forming a positive rifling.
When the smooth part of the hard top cone is forced through the inner wall of the gun bore, the gun bore will become smoother except for the smooth inner wall required at the yin and yang rifling areas.
In this way, the service life of the gun barrel will be doubled."
The firearms manufacturer Chen Gui and his deputy Huan Li Ji were so impressed that they fell to the ground after listening to Zhao Guanjia's explanation...
In fact, the cone extrusion method for making musket rifling given by traveler Zhao Ji was first invented by the Germans. After the 1970s, this method has been widely used by various countries in the production of gun barrels.
Zhao Ji knew that the replacement of the 'rifling top cone extrusion method' was the 'cold precision forging method'. This method of manufacturing firearm rifling is the most advanced.
Because the precision forging process can improve the strength and shooting accuracy of the barrel, thereby increasing the life of the barrel and reducing the drop in muzzle velocity, it plays a key role in improving the performance of the firearm.
However, the modern technology content required is also higher.
In modern society before Zhao Ji traveled through time, both many developed countries in the West and our own country were using the 'cold precision forging method' to make the rifling of firearms...
He knew that with the current industrial and technical capabilities of the Song Dynasty, it would be difficult to implement the 'cold precision forging method'.
However, he still briefly introduced Chen Gui and Li Ji.
Zhao Jidao: "The fifth method of making musket rifling is called 'cold precision forging method'."
"Using this method to make musket rifling requires a professional precision forging machine.
To forge the rifled barrel and the bullet chamber from the blank of the gun barrel at one time, it is a chip-free precision forming technology, and the accuracy of the inner bore must be guaranteed by the mandrel.
In the Song Dynasty, it is difficult to use the "cold precision forging method" to produce musket rifling.
Therefore, firearms manufacturers do not need to consider using this method to make musket rifling in the past three years.
You can just focus on the first four production methods I gave you."
"I obey the decree." After hearing this, Chen Gui was so excited that he knelt on the ground and thanked the Holy Father repeatedly for his grace.
When he first heard every method of making rifling described by Zhao Guanjia, he felt like he was listening to a book from heaven;
However, after Zhao Guanjia explained it to him in detail, he would suddenly realize that he was suddenly enlightened, just like parting the clouds and mist to see the sun, holding on to the clouds to see the moon...
Chen Gui looked at the five pieces of rice paper he had recorded. He silently wrote down the five methods of making musket rifling given by Zhao Guanjia:
One is the ‘scraper method’…
The second is the ‘hook knife broaching method’…
The third is ‘combined ring tool broaching method’…
The fourth is the ‘Rifling Cone Squeezing Method’…
The fifth is the ‘cold precision forging method’…
…
"Chen Aiqing, please get up quickly." Zhao Ji stepped forward, helped Chen Gui up with his own hands, patted his shoulder enthusiastically, and said:
"Chen Aiqing is both intelligent and courageous, with outstanding talents. He is a genius in firearms manufacturing..."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Hearing this, Chen Gui was so excited that he burst into tears and murmured:
"I would like to thank Your Majesty for the compliment. However, it is difficult for me to accept such praise.
Wei Chen led the craftsmen in the firearms manufacturing workshop and was able to develop so many firearms, all thanks to the firearms manufacturing design drawings given by His Majesty!"
"Hahaha..." Zhao Ji laughed loudly and then said:
"Chen Aiqing, although I am interested in the development of firearms and have drawn many firearm design drawings, after all, I am busy with political affairs and cannot do it myself, so I need help.
Chen Aiqing and Li Aiqing, as well as the craftsmen in the firearms manufacturing workshop, are my right-hand men who want to strengthen the ordnance!"
Chen Gui and Li Ji immediately knelt down, kowtowed and said:
"I am willing to do my best for Your Majesty! Long live my emperor!"
Dozens of representatives of craftsmen from the firearms manufacturing workshop also knelt down and kowtowed, shouting in unison:
"We are willing to do the hard work of dogs and horses for Your Majesty! Long live my emperor..."
Zhao Ji nodded with satisfaction and said loudly: "Everyone loves you."
Everyone stood up...
Zhao Ji gave Chen Gui the secret of firearms manufacturing:
"The method of making musket hall lines can also be used in the barrel of the gun."
“Also, whether it is a musket or an artillery piece, with suitable rifling, its range will be longer and its hit accuracy will be higher;
However, if you still use the front-loading method, the friction will increase due to the rifling. Even if you use the method I gave you to wrap the projectiles with oil-soaked linen cloth, the speed will become slightly slower.
Some."
Chen Gui, the first person to make muskets, suddenly realized it again when he heard Zhao Guanjia's words. He felt that Zhao Guanjia had thought too carefully.
Zhao Guanjia’s words make sense!
Chen Gui frowned and tried hard to think of a solution...
However, even though Chen Lu was extremely clever, he couldn't come up with a good solution for a while.
Zhao Ji smiled slightly and said, "I have a few good ideas!"
Firearms manufacturing envoy Chen Gui and deputy envoy Li Ji were both amazed at how smart the Zhao Guan family was!
The two of them thought about the things that gave them a lot of headaches. Zhao Guanjia was able to think of a good solution in a blink of an eye. He was really a genius!
Chen Gui and Li Ji look forward to Zhao Guan's family coming up with a good solution to the problem...
