Li Zhi walked in the machine tool factory, looked at the newly produced planers and milling machines, and nodded.
The so-called planer is a linear motion machine tool that uses a planer to plan the plane, groove or formed surface of the workpiece. This type of machine tool has high processing accuracy and is suitable for processing a small number of high-precision workpieces.
A milling machine is a machine that uses a high-speed rotating tool head to process flat surfaces, grooves, curved surfaces, gears, etc., and is more efficient.
With the continuous equipment of various machine tools, Fanjiazhuang's industrial level has reached the level of the early 19th century. This is very critical for the large-scale production of steam locomotives. Otherwise, without various machine tools and manual polishing, the manufacturing cycle of steam locomotives will be shortened.
Very long and the cost will be very high.
However, Li Zhi came to the machine tool factory to inspect today not for the steam locomotive, but to see if the machine tool factory could produce a breech-loading rifle.
"Han Jinxin, you said Jiangbei Army has begun to equip new rifles in batches?"
Han Jinxin nodded, raised his hands and said: "My lord, the informant reported that the Jiangbei Army recruited gunsmiths from several provinces near Jiangxi to build a new rifle. According to the informant's observation at the training ground, this new rifle can
If you hit 200 meters, you can hit three rounds in one minute."
Li Zhi pondered and said: "Two hundred meters, isn't this the same as our standard rifle without a scope?"
Han Jinxin said: "That's it, Mr. Guo."
Li Zhi took a breath and secretly thought that the secret of the Mini rifle may have been discovered by people of this era. The trick of the Mini rifle is too simple. The key is a bullet design with a hollow tail. This secret has been kept for ten years.
Li Zhi felt very relieved to have just been controlled by other forces.
However, now that other forces have begun to equip Mini rifles, Li Zhi must upgrade his own armaments and continue to maintain a technological lead.
This is a very urgent problem. The number of Jiangbei Army is more than twice that of Huben Army. If the technical level of Huben Army cannot surpass Jiangbei Army, it may be defeated by Jiangbei Army.
If the Huben army is defeated, the prosperity of one town and four provinces will disappear. Li Zhi's career will be a complete failure.
Li Zhi shuttled back and forth among various machine tools, watching workers busy manufacturing components for steam locomotives on the machine tools.
Now Fanjiazhuang's machine tool factory has entered a stage of independent evolution. Without Li Zhi's guidance, the craftsmen in the machine tool factory can continuously improve the accuracy of machine tools according to the actual needs of production. The current accuracy control has reached a quarter
mm level.
For the first-generation steam locomotive, this accuracy was enough, but for a breech-loading rifle, this level was still a little behind.
In Li Zhi’s memory, when breech-loading rifles appeared in the mid-19th century, European machine tool processing accuracy had reached one-tenth of a millimeter. A breech-loading rifle often had five or sixty components, which was a large number of small components.
The gadgets are assembled. However, after the final assembly into a rifle, the bolt action is required to be highly airtight, which extremely tests the processing accuracy.
The most famous early breech-loading rifle is undoubtedly the Dresser needle gun. This rifle made a splash in the Austro-Prussian War in 1866, helping Prussia defeat Austria, which used the Minie rifle. But in fact, as early as the 10th century
In the 1920s, several breech-loading rifles were launched in Europe.
These premature breech-loading rifles are undoubtedly unpopular. It is precisely because the air tightness is too poor that the range and accuracy are far lower than those of muzzle-loading rifles, and they have no actual combat value.
If Li Zhi wants to produce breech-loading guns, he still has to wait for the machine tool factory to upgrade and improve the accuracy.
Moreover, breech-loading guns use primers, which involves the production of mercury fulminate, which is also a difficult problem. Mercury fulminate is not only extremely unstable, it is easy to explode during the production process, and it is also highly toxic. If you want safe production
Mercury fulminate is by no means a simple matter.
After walking around the machine tool factory, Li Zhi understood that it would take time to build a breech-loading gun.
But that doesn't mean that without a breech-loading gun, it's impossible to technically overwhelm the Jiangbei Army. As an industrial designer, Li Zhi, of course, had other ways. He took Han Jinxin and walked into the foundry factory in Fanjiazhuang.
The technology of the foundry under Li Zhi is also constantly improving. It originally took several days to cast an iron-core copper-bodied cannon. It took a lot of time to manually find the center of the casting and adjust the position of the iron core and the molten copper. However,
Nowadays, this kind of proofreading work is handed over to specially designed machines, and the production speed has been greatly improved.
Advances in technology have made it possible to cast new bullets on a large scale. The work of finding the center used to take a lot of time, but now it can be done in batches with the help of machines.
As soon as Li Zhi walked into the foundry, he saw the shelves at the door filled with freshly baked steel-core lead bullets.
Li Zhi picked up a steel-core lead bullet from the shelf and looked at it. He found that the steel core in the middle of the bullet was very hard. This steel core uses the best crucible steel in Fanjiazhuang and is used to break armor. Then in the steel core
The outside of the gun is cast with a layer of lead. The lead is relatively soft, which can ensure that the bullet twists and rotates with the rifling in the bore.
Li Zhi handed a steel core bomb to Han Jinxin to look at.
Han Jinxin said: "My lord, this new bullet seems to be harder than lead bullets."
Li Zhi smiled and said: "This new bullet should be able to penetrate the double-layer heavy armor of Jiangbei Army. Let's go to the shooting range and try it."
Li Zhi asked a worker to carry a box of steel core bullets and walked to the shooting range outside Fanjiazhuang City.
On the shooting range, Li Zhi had someone set up a heavily armored scarecrow wrapped in heavy cotton armor and iron scale armor, and he stood at a distance of two hundred meters and fired with new bullets.
With a crisp "pop" sound, Li Zhi fired the bullet 200 meters away, and the scarecrow 200 meters away fell down in response.
Li Zhi asked someone to bring the scarecrow over, and sure enough he saw two holes in the scarecrow's armor.
Han Jinxin said in surprise: "Master Guo Shenwu! This new type of bullet is really sharp. In this way, we can kill the heavy armored soldiers of the Jiangbei Army from a long distance!"
Li Zhi nodded and asked the soldiers to set the target farther away, to 250 meters.
With a "pop" shot, there were two more holes in the scarecrow's armor.
Li Zhi moved the scarecrow further and shot at 300 meters.
Finally, Li Zhi discovered that the steel-core bullet could penetrate two layers of armor at a distance of three hundred meters. If it was further away, it would not be able to penetrate.
Li Zhi grabbed the rifle and said: "Jiangbei Army's soldiers have to be two hundred meters away to attack us, but our soldiers can kill Jiangbei Army at three hundred meters away. In addition, we use smokeless gunpowder, and the soldiers don't need to clean up."
The gun chamber and the rate of fire are higher than those of Jiangbei Army. We are one generation ahead of Jiangbei Army in technology." chaptererror;
