The sniper starts from the bright sword escape period

Chapter 414 Daming's firearms are afraid of rain!
People in the East saw things that could only be used for grinding jade, but in the West they were used for metal shaping.

Later, a Westerner named Besson designed a lathe for turning screws that slides the tool through the screw rod. The tool is finally no longer fixed in one position, and this is already a bit like a modern machine tool.

You must know that screws are an important part of modern industry and an indispensable thing.

However, although the functions of the machine tool are constantly enriched and the prototype is constantly developing, the power source is still not separated from the original tree lathe. The continuous power is really a big problem. After all, no matter how powerful a person is, he will still be tired.

Of course, some people have thought of using waterwheels as long-term power for machine tools, but such machine tools can only be built on the edge of rivers, and the flow speed of the river in four seasons cannot be controlled, so it is naturally very troublesome.

However, the appearance of the steam engine brought the machine tool into a new era.

Of course, when it comes to steam engines, Watt is inseparable. Although Watt is not the inventor of the steam engine, he is the improver of the steam engine, allowing the steam engine to be truly applied.

So the story of Watt and the teapot in childhood is still being passed down to this day.One evening, Watt was having tea at home with a little girl.Watt kept fiddling with the lid of the teapot, opening it and closing it, and when he plugged the spout, the steam pushed the lid open.The grandmother beside him was extremely dissatisfied with Watt's boring action and reprimanded him.Watt didn't mind, he was obsessed with the power of steam, and from then on he had the idea of ​​making a steam engine

Of course, history is by no means that simple.Watt absorbed the achievements of his predecessors and his personal hard work, improved various parts of the steam engine, and improved the power efficiency.The story of Watt's invention of the steam engine is not so dramatic, but it is far more exciting than this fairy tale.

In 1763 the University of Glasgow in the west hired a technician named Watt and his task was to maintain, more like repair a newcomen steam engine in the school, a wet rope held the parts together and it always broke .

The Newcomen steam engine was the predecessor of the Watt steam engine. Watt improved the cylinder part based on Newcomen's design, but one of the main reasons for repeated failures in research and development was that the hand-hammered tin cylinder always leaked air.

At this time, the appearance of Wilkinson played a huge role in Val's improvement of the steam engine.While Watt was still proud of his 3/8-inch thick real cylinder, Wilkinson had his own lathe.As a master of steel, Wilkinson invented the barrel boring machine in 1774, which is the world's first real boring machine.

Of course, the barrel boring machine invented by Wilkinson was originally used to cast munitions

In 1775, Wilkinson used the cylinder bored out by this barrel boring machine to remanufacture Watt's flawed cylinder, which met the requirements of Watt's steam engine.Of course, as a businessman, Wilkinson also obtained the exclusive right to supply cylinders for Watt's steam engine.

In order to bore larger cylinders, he manufactured a cylinder boring machine driven by water wheels in the same year, which promoted the development of steam engines.From then on, the machine tool began to be driven by the steam engine through the crankshaft. For the machine tool and the steam engine, this mutual assistance promoted the common development, so a vigorous era of industrial development went to the extreme.

The name Mozley is naturally inseparable from the machine tool. In 1797, the father of the machine tool industry made the first thread cutting lathe, which has a screw rod and a polished rod, and uses a sliding tool holder-Mohs tool holder and guide rails. , can turn threads with different pitches.Since then, Maudsley has continued to improve the lathe.The lathe he made in 1800 replaced the triangular iron bar frame with a solid cast iron bed, and used idler gears to exchange gear pairs instead of replacing lead screws with different pitches to turn threads with different pitches.This is the prototype of the modern lathe, which is of great significance to the development of Western industry.

But these are too far away for Bailixiu. After all, what Bailixiu has to do now is how to strengthen Ming's war potential and create a more powerful war machine.

For example, Bai Lixiu came up with a machine tool that can cut metal. In fact, the most important purpose is to improve the production method of Daming's firearms.

After all, a gun barrel hammered by a blacksmith, or a gun barrel poured by pouring, will never be as good as a gun barrel drilled and cut by a machine tool.

You must know that whether it is a barrel made by a blacksmith with iron sheets or a barrel poured by pouring, the smoothness and airtightness of the inside of the barrel cannot be guaranteed.

Of course, the most important thing is that the barrel drilled out of the drill hole has a stronger pressure resistance, which means that more gunpowder can be placed in the barrel while ensuring that the barrel is light enough, so that the bullet can shoot at a higher initial velocity , a greater distance.

After Bailixiu made a demonstration, Lao Li and Lao Zhang couldn't wait to use it, and then found that this machine tool could cut a steel bar into a very round shape.

Except for the two blacksmiths who tried it, even Prince Zhu Biao also tried it, but he said after a while:
"This machine tool is good, but it's really tiring to step on it like this all the time!"

When Bai Lixiu heard this, she waved her hands indifferently and said:
"It can be replaced by animal power, or by the power of waterwheels, instead of human power!"

Then Bai Lixiu glanced around, and found that the blacksmith's room of the military battle bureau was full of firearms.

Of course, these firearms are not the firearms of the world before Bailixiu traveled, but firearms that are hundreds of years behind.

For example, the firecrackers in the military battle at this time are not semi-mechanical matchlock guns, but a mechanism that needs to hold a firecracker in one hand and a torch in the other.

In fact, whether it is a gun ignited with a torch, an arquebus ignited with a rope, or a flintlock ignited with flint.

All three of them have a big, big flaw, that is, they are afraid of water. That's right, once they encounter wet weather or rainy days, then these firearms will be useless.

Of course, not only muskets, but also cannons that rely on torches to ignite.

However, Zhu Yuanzhang defeated the cavalry of the Northern Yuan Dynasty by relying on such backward firecrackers, and the three-stage shooting method is not a Western patent. Zhu Yuanzhang invented this method as early as the early Ming Dynasty to defeat the Northern Yuan Dynasty. The cavalry charged.

Of course, it was the Maxim heavy machine gun that made the cavalry completely withdraw from the stage of history. You must know that it was precisely because of the appearance of the Maxim heavy machine gun that the group charge became history.

In front of the Maxim machine gun with a rate of fire of hundreds of French per minute, hundreds of thousands of cavalry charge is a live target. It is precisely because of the appearance of this gun that the Huns who once dominated the world have become a hospitable and good at singing and dancing. shepherd.
