Datang romantic little landlord

Datang inherited the Sui Dynasty's "Da Ye Li", and the accurate timekeeping used a tool called leaking.

It is a tool for timing by dripping water. A day is divided into twelve hours, each hour is five hundred minutes, and one minute is equivalent to 14 seconds.

In other words, this one-ton hydraulic forging machine can be hammered eight times a minute, which is quite impressive.

Li Wangyou asked curiously again: "Liben, how did you solve the problem of the hammer head swinging?"

The biggest problem with this primitive hydraulic forging machine is the poor precision of hammering, making it difficult to perform fine processing like the forging machines of later generations.After all, every time the hammer head rises and falls, it will swing from side to side to a certain extent, which is normal.

But to stamp and forge copper coins, it is necessary to let the hammer head fall on the same point every time.

It was because Li Wangyou didn't know how to solve this problem that he simply became the hands-off shopkeeper and left everything to Yan Liben to figure it out.

Yan Liben was very proud, and pointed to the thick lever connecting the hammer head.

"Teacher, I made a device connection lever here, so that it slides into this funnel-shaped hole when it falls, so as to ensure that the hammer head is in the same position every time it falls."

Li Wangyou pondered for a long time before he roughly understood Yan Liben's design, and couldn't help but give Yan Liben a thumbs up.

Great, really great.

Whoever said that the ancients were not smart, Li Wangyou would definitely not be able to think of this kind of device if he made it himself.

Yan Liben smiled a little embarrassedly after being praised by his teacher.In his opinion, these are mainly Li Wangyou's ideas, and he is just implementing the teacher's design.

However, Yan Liben was very happy to be affirmed by the master, and pointed to the craftsman who was busy in front of the forging machine and said: "Master, please look, the hammer head and the base below are all stamping dies made of high-quality stainless steel." The craftsman puts the cast copper bar on the mold, and when the hammer head falls by itself, a fine copper coin is cast. Compared with the casting of coins in the past, I don’t know how much simpler it is, and only one person is needed The craftsman can manipulate it. The teacher is a great talent, and the disciples really admire it."

Li Wangyou didn't blush, and accepted Yan Liben's praise. Anyway, he was used to being "flattered" like this, and his face was getting thicker and thicker.

He nodded and smiled pretentiously, watching the craftsman mint coins.

As the water flow drove the waterwheel to rotate, the hammer head was raised high, then fell heavily, and with a loud bang, it accurately hit the copper bar below.

The hammer head was lifted slowly again, and a copper coin shining with metallic luster fell into the bamboo basket below, making a crisp and pleasant sound.

Li Wangyou reached out to pick up the freshly baked copper coin. The words "Kaiyuan Tongbao" were evenly spaced, clear and powerful.

These four characters were not written by ordinary people, but by Ouyang Xun, a great calligrapher.

Li Wangyou took out another official coin from his purse for comparison.

The weight of the two coins is about the same, but unlike the minted copper coins, the stamped copper coins are finer and have more metallic luster.

If one had to choose an official coin from these two coins, Li Wangyou believed that most people would choose the stamped coin.

"How many of these stamping machines have been built?"

"There are already ten units, and the others are still under construction."

Li Wangyou calculated silently in his heart, a hydraulic stamping machine can punch eight times in one minute, that is to make eight copper coins.

One hour is 480 copper coins. If three shifts work in one day without stopping work, more than 700 copper coins can be pressed, and ten sets can make 57 copper coins a day.

This is very different from when I and Li Er boasted that they could make thousands of copper coins a day.

However, this hydraulic forging machine can continue to be expanded. If there are 500 sets, it can produce more than [-] copper coins per day. If there are [-] sets, then the daily production of [-] guan is not a problem.

"Haha, Liben, you have done better than you thought for your teacher. Niu Wu, you immediately take my goldfish talisman, go to the Tai Chi Palace, and find Mi Tuo. Let him tell the saint that the minting of coins has been completed, and see if the saint You have to come and check it yourself. Go and come back quickly, I will wait for you here."

"No!" Niu Wu didn't dare to hesitate, took Li Wangyou's goldfish talisman, and ran out of the workshop...

512 Great Tang Knife

In the mint workshop, the hydraulic forging machine was beating non-stop all the time, making a loud noise.

After staying in the workshop for a while, Li Wangyou felt upset and couldn't stand the noise, so he simply pulled Yan Liben out to talk.

"Liben, do you know that this hydraulic forging machine has other uses?"

"Returning to the teacher, since the disciple made this forging machine, he has already thought about it. If my craftsmen of the Tang Dynasty used this to forge armor and weapons, it would definitely be able to get twice the result with half the effort. Nowadays, the best thing in the Tang Dynasty is Baisteel, which consumes a lot of energy. It takes a lot of time and effort, but if the disciple reduces the weight of the hammer head and makes the beating speed faster, then refining steel is not a difficult task, and it is easy to forge a large amount of refined steel. It is hard for the disciple to imagine that such a large-scale forging How strong and sharp the resulting weapon will be."

The hundred steelmaking that Yan Liben mentioned was a kind of steelmaking process of Datang.

The fried steel is repeatedly heated and forged, hammered and tempered until a hundred times.Repeated forging can remove impurities in the steel and make the steel harder.

Bailian Steel repeatedly folds and forges steel, which is very difficult to make and the output is extremely rare.All that can be forged by this method are treasured swords in the world.

As for the steel used to make armor, it doesn't need to be like a sword or a weapon. The steel needs to be soft, thin and tough.Anyway, Li Wangyou didn't understand these things, he only knew a general idea.

But with great craftsmen like Yan Liben and his elder brother Yan Lide, and many skilled craftsmen in the Tang Dynasty, Li Wangyou didn't bother to think about these things, he just provided an idea.

"Haha, Liben, you have already thought of it. Yes, this hydraulic forging hammer is used to forge steel, which is perfect. This matter will be explained to the sage, why not build another ordnance workshop in this Huangyu, It is used to forge armor and blades. Liben, are you interested in taking over the construction of this workshop?"

"Of course Liben is willing." Yan Liben was overjoyed. What he likes most is actually these things about construction. He certainly agreed to Li Wangyou's words.

The master and apprentice chatted happily, Li Wangyou simply dismissed the trilogy, and rode back to the mansion to fetch tea from the stove.The two of them, Yan Liben and Yan Liben, enjoyed the beautiful scenery on the bank of the Qi River, while sipping tea and chatting about making various weapons.

As a man, there is no one who doesn't like swords and armor, and Tang Dao is famous in history, so Li Wangyou is naturally interested.

He has traveled to Tang Dynasty for more than half a year, but he has never seen the real Bailian sword.What Li Er was wearing was supposed to be the Bailian Baodao, but he couldn't ask Li Er to give him his saber for fun.

Yan Li himself is the young supervisor who will serve as the supervisor, and he is very familiar with the sword system of the Tang Dynasty. He gave Li Wangyou a detailed introduction to the advantages and disadvantages of various knife systems of the Tang Dynasty, which Li Wangyou talked about with great interest.

There are four kinds of knives in the Tang Dynasty. According to the "Liu Dian Wu Ku Ling" of the Tang Dynasty, "there are four types of knives, one is called Yi Dao, the second is called Zhang Dao, the third is called Heng Dao, and the fourth is called Mo Dao."

The Ritual Knife is a sacrificial instrument, worn by officials of the Tang Dynasty and the imperial guards in the palace, and the one worn by Li Wangyou is a Ritual Knife.Zhang Dao is a short knife, shaped like a dagger, used for self-defense.

Hengdao and Modao are the real murder weapons.

Mo Dao is a long sword with a huge shape and two edges. When it is arrayed, it "goes in like a wall", and when it is swung, it can "shatter people and horses." It can be called a big killer.

The Mo Dao is about three meters long, the blade and the handle are each 1.5 meters long, and weighs about fifty catties.Datang's Mo Dao players are all strictly selected soldiers with extraordinary strength and courage, otherwise they would not be able to wield the heavy and slender Mo Dao.

A well-equipped Mo Dao Shou costs at least three thousand copper coins, which is a huge expense. Even Datang is difficult to equip in large quantities.But Mo Dao Shou's deterrence and combat effectiveness are extremely strong, and this is the only infantry that can face the cavalry's impact head-on.

Facing the impact of the cavalry, the Mo Dao, which is like a wall of swords, can cut the cavalry into two sections, including men and horses, and its power can be imagined.

Li Wangyou just had to think about Modao as a big killer, and he couldn't handle it if it was given to him.

And Heng Dao is what Li Wangyou is most interested in.

He knew that the horizontal sword was the originator of the later Japanese samurai swords, but the horizontal sword has no curvature and the blade is straight.

In history, Hengdao was once given as a gift to members of the mission to Tang Dynasty and brought back to Japan by them.Subsequently, it was introduced to Japan, as well as the making technology of horizontal swords, which later evolved into samurai swords.

Seeing that Li Wangyou was very interested in horizontal knives, Yan Liben immediately pleaded his chest and promised that when the ordnance workshop was completed, he would definitely make a hundred-steel horizontal knives for his teacher.

Li Wangyou naturally nodded and smiled, but he asked someone to fetch a pen and paper, and drew a picture of the Song Dynasty's saber on it.
