Chapter 413 Daming's Human Machine Tool

Naturally, Bailixiu asked this question to understand what Zhu Yuanzhang meant!

After Zhu Biao heard Bailixiu's words, he also understood another layer of meaning in Bailixiu's words, that is, if Zhu Biao denied Bailixiu's strategy of flattening the Huns and just wanted to keep it, then Bailixiu Xiuhe would not tell the manufacturing method of the glazed mirror and the bearing of the four-wheeled carriage.

When Zhu Biao understood Bailixiu's meaning, he couldn't help thinking of what Zhu Yuanzhang said to Zhu Biao yesterday after he decided to ask Bailixiu for a method of manufacturing carriage bearings.

Thinking of this, Zhu Biao immediately said:

"Royal father, naturally he wants to expand the territory and show the great power of the Tang Dynasty!"

Hearing Zhu Biao's words, Bailixiu was quite satisfied, but she still said:
"To surpass the prosperous Tang Dynasty, doesn't the emperor of Ming Dynasty want to be more powerful than the emperor of Datang Dynasty? You must know that Genghis Khan, the former founder of the Northern Yuan Dynasty, conquered a much larger territory than the Tang Dynasty. Does His Royal Highness think that we Han people are not as good as us?" The Huns?"

Zhu Biao didn't know how to respond to Bailixiu's words. You must know that the territory of the Menggu Empire at the peak of the Yuan Dynasty exceeded [-] square kilometers, more than twice the territory of the Tang Dynasty at its peak!
And after Zhu Biao took over the supervisory power of Daming, he realized that it is not an easy task to govern Daming well.

So it is even more difficult to expand the territory. After all, Beiyuan alone is not so easy to deal with.

So not to mention surpassing Beiyuan and reaching the territory of the Menggu Empire before its split.

Seeing Zhu Biao's silence, Bai Lixiu naturally understood that he had no confidence in surpassing the Menggu Empire, so he also sighed and said:
"Let's go! Take me to see how your craftsmen build a four-wheeled carriage!"

Zhu Biao was overjoyed when he heard Bailixiu's words, and realized that it was Bailixiu's plan to teach the method of manufacturing the roller bearings of the four-wheeled carriage.

Immediately, he took Bai Lixiu to the place where Daming's weapons and armor were manufactured, the military battle bureau.

And Zhu Biao said to Bailixiu while leading the way:

"Sir, we can understand the structure of this four-wheeled carriage after reading it once, but the steel bearings made by the sir for the four wheels of the four-wheeled carriage can't be made by the best blacksmith in the Military Bureau. Pillar come!"

After Bai Lixiu heard this, she naturally smiled slightly. It would be strange if they could create such a round roller!
When Zhu Biao was talking, he had already brought Bai Lixiu to the blacksmithing area of ​​the Bingzhan Bureau, and the sounds coming out of it were of course the clanging sound of iron striking, but there were two sounds that were louder than this sound of iron striking. Be big.

"Old Zhang, don't waste your efforts anymore. Such a round cylinder was definitely not made by hammering it with your hammer, it must have been processed by other methods!"

"Old Li, if you can't knock it out, it doesn't mean I can't knock it out. As long as you knock it a few more times, you will definitely knock out such a round cylindrical iron."

When Bai Lixiu walked in, he found that the two quarreling people were two men in their forties who were wearing coarse jackets.

Seeing Bai Lixiu looking at them both, Zhu Biao explained from the side:

"Mr. Baili, these two are the best blacksmiths in the Military Bureau. However, they have been researching since the afternoon before yesterday. They have been researching for a day and two nights, but they still haven't produced the bearings like the one in the carriage of the gentleman!"

After hearing Zhu Biao's introduction, Bailixiu said with a smile:

"What blacksmith Li said is actually good, but such a round iron pillar is not made by beating, but cut!"

Bai Lixiu took out the Xingyun carving knife as he spoke, and cut out a very round iron pillar on an iron plate in the blacksmith's room with a single stroke! "

However, Bailixiu's move made Zhu Biao a little disappointed, because Zhu Biao could see that the Xingyun carving knife in Bailixiu's hand could cut iron like mud. It is definitely not easy to make things, which naturally means that they cannot be mass-produced.

Bai Lixiu naturally saw the disappointment in Zhu Biao's eyes, so she continued to say:

"Of course, my carving knife that cuts iron like clay is not an ordinary product, but it is unique in the world made of meteorites from outside the sky, but I still need a way to make cylindrical iron with a roundness similar to this!"

After talking, Bai Lixiu found some tools from the military bureau, and started to process them.

After a while, a very simple manual flywheel machine tool was created by Bailixiu.

Then Bailixiu showed them a demonstration. First, he put a soft steel rod that was not very smooth and had not been quenched on the machine tool, clamping one end to the other end, and then Bailixiu stepped on the pedal to drive the flywheel. Rotate, and the inertia of the flywheel's rotation naturally also drives the iron rod clamped on it.

Then Bai Lixiu approached the soft steel rod with a quenched sharp knife, and then cut with the quenched hard knife, and soon the soft steel rod, which was not very round, became perfectly round.

Bailixiu's operation naturally stunned the two blacksmiths. They didn't expect to be able to use it like this. You know, they also understand Bailixiu's structure, because in their In the blacksmith's shop, someone used this method to make a round whetstone into a shape that could be turned by hand, so as to sharpen the forged Xiuchun knife.

In fact, this structure of machine tools appeared more than 2000 years ago.

As a prototype, it is still relatively rough to tie two pointed wooden sticks between two trees, and then press a piece of wood between the two wooden sticks, and then wrap a rope around the wooden stick several times. Then one end of the rope is tied to the branch and the other end is tied with a knot loop and suspended in the air with your feet.

When operating, step on the ring under the rope with your feet, use the toughness of the branches to drive the workpiece to rotate, use stone flakes or shells as knives, and use the knives to cut the items along the horizontal strip. The tree lathe is exactly as its name suggests.
Then in the [-]th century, the prototype of the machine tool was also developing. You can’t always hang it on the tree. At this time, you use the pedal to rotate the crankshaft and drive the flywheel, and then transmit it to the main shaft to make it rotate. "Pedal lathe", also known as It's called a flexible bar-and-rod lathe, but the operating principle is exactly the same as before, except that the tool is made of real metal.

In fact, this structure is not just a patent of Westerners. It is recorded in the creation of heavenly objects in the Ming Dynasty in the East. Some people used this method to grind jade.

It's just a pity that this kind of application is only here, and the principle of this machine tool has not been used to create more useful tools.

Just like in the eyes of these blacksmiths, if you want to shape iron, you can only do it by heating the iron and then hammering it, or pouring it.
