Stamping is simple to say, but Hong Jinglai knows that it is not easy to do. In the past, he only thought about things like carding machines and spinning machines. After all, "sheep eat people", and flying shuttles, etc., for the first time in history textbooks

There is a heavy emphasis on writing and ink in Industrial Ge Ming.

No wonder Hong Jinglai remembered these things clearly. They are all textile things, and they should all be considered in the light industry sector. The stamping machines for making currency are obviously not included in this list. It will still take some time to develop them from scratch now.

of.

At most, it's good that you can directly set the goals and follow the results to push the process. It's better than having to start all over again. Let's put forward an idea first, and the rest is to arrange for those Beijing students.

And skilled craftsmen are working on it. Don’t be afraid of trial and error, just go for it.

Ding Ruoyong and a group of students from the north were summoned to Beijing. Hong Jinglai had to have a good chat with them before the end of the year was busy. After all, he could only start minting new currency if he got the equipment.

The first is the engraving mother as a template. In later generations, there is naturally such a thing as an engraving machine. It is really easy to make a so-called engraving mother. After drawing the picture on the computer and setting up the program, the engraving machine will not be needed.

How long does it take for the item to be shipped? Anyway, it doesn’t mean that you need to make some exquisite handicrafts, as long as they are almost the same.

At the moment, Hong Jinglai felt that the engraving machine was not necessary. He could simply omit this step and find a few skilled craftsmen to start engraving gold and silver coins. It did not require thousands of engraving mothers, which would be enough.

It seems that the mold turning machine is not very necessary for the time being. Anyway, it is minted in Hanyang. At most, in the future, additional mints will be opened in Yiju, which trades with Qing Dynasty, and Dongnae, which trades with Japan. Manual mold turning is enough.

Some subtle differences will not affect the use. Again, it is not a handicraft.

After having the mold, the next step is to prepare the materials for coining. Of course, it is impossible to throw a large pile of silver or red copper on the ground and the stamping machine will hit it. That is not a joke.

According to Hong Jinglai's memory, a batch of materials needs to be mixed and melted first. As mentioned before, the copper coins are only prepared to contain 55% copper, and then 40% lead, and the rest is tin and lead.

, like metals such as iron. Stir them all evenly, melt them together, and cast them into strips (stick shapes).

Then it enters the steam rolling machine, and the metal strip is rolled into coin-thick metal sheets through the rolling machine. Only in this way can the basic steps before stamping be completed, and coin making can begin.

Put those metal sheets or metal plates under the steam stamping machine (punch), and use the power of the steam engine to press the plate for a while, and the money is considered completed.

The rough procedure should be like this. Hong Jinglai can only give you a basic thing. In actual operation, it should be strengthened or improved in any way. But the benefits of doing it this way are quite obvious, such as stamped coins and edges.

It will be in the shape of a kind of fine gear, which can be regarded as some kind of anti-counterfeiting mark, and it can also prevent someone from cutting the edges.

However, there are so many human beings involved in the whole process. It is unlikely that the finished product will be as exquisite as those in later generations with big heads and small heads, standing in foreign countries and sitting in foreign countries. At most, it is just for use.

After explaining this whole set of procedures and ideas to Ding Ruoyong, Ding Ruoyong felt that there was nothing wrong with it and said that this idea was completely feasible, and the only problem was the actual development of various types of machinery. According to him, he had seen similar projects before.

Introduction, it seems that a European named Leonardo da Vinci (I really don’t know what North Korea calls this person) had already developed such a set of things hundreds of years ago.

From what he said, it seemed that Leonardo da Vinci had even built a manual flaking machine without relying on the power of a steam engine. There was also some kind of manually operated spiral press, but that thing couldn't use animal power or water power.

It was inconvenient to press. More importantly, because the technology at the time was not up to standard, it seemed that only gold and silver coins could be stamped. These two metals were relatively soft and could produce clearer graphics. But copper coins could not be stamped because copper coins were relatively soft.

It is harder and the suppression effect is very poor.

This is the first time I heard that Hong Jinglai only knew that Leonardo da Vinci was a great inventor. It is said that he invented thousands of various items in his life, and even had the prototype of an airplane. Unexpectedly, he also designed a coin-minting machine, and he heard that he also designed a coin-minting machine.

Jeong Yak Yong's description seems to have been popularized and used. However, now that steam engines have emerged and metal smelting technology has improved, it has been eliminated.

With a word of admiration in his heart, Hong Jinglai also agreed with Ding Ruoyong's opinion. Although it is an obsolete thing, if there is a machine that can be used as a reference, it is not a bad thing to just get a set and take a look. The eliminated things may be behind the times.

It has changed with the times, but it may not be used in North Korea.

After all the discussions were made, Hong Jinglai handed over the items he had scrawled to Jeong Yao-yong. Hong Jinglai immediately decided to appoint Jeong Yao-yong as the chief executive of Sungkyunkwan (from the third rank). From now on, he would travel between Hanyang and Incheon to take care of both. Those who can do more work

Well.

There is nothing wrong with Ding Ruoyong. Anyway, he is basically tired of political struggles. He should be an official of Tsinghua Literature, do research, and teach students what he is happy to do now. He just wants to use the little free time he has left.

Writing a book and establishing a theory. It is obvious that this person has transcended. He feels that fighting to the death is meaningless now. It is better to leave a book, become famous in history, and be remembered for generations.

Good!

It is not easy to be a pure person, but Jeong Ruoyong has obviously begun to be a pure person. His years of exile have completely shaved off all the edges and corners in his body. What is left to North Korea now is a great scientist and great scientist.

Scholar.

The issue of currency minting has been arranged, and it is difficult for Hong Jinglai to appease the three major business groups. After all, when there is not enough currency, including the Beijing business group that has been overthrown, these large business groups can make money from this.

A lot of money.

Although it is impossible for Hong Jinglai to mint any huge currency with a denomination of ten taels and twenty taels, or even fifty taels and one hundred taels, the three major business groups can still continue to issue medium and large denominations to make profits. However, those who accept miscellaneous silver and silver and copper exchange

Such a way to make money would be blocked by Hong Jing.

They are all the younger brothers who followed him to conquer the country, but when he came on stage, he took the meat from their mouths. It was too unethical. We still need to have a good talk with Lin Shangwo and Li Xizhu about this matter and listen to their opinions. Don't push it yourself.
