My Daming New Empire

What everyone didn't expect was that because the crankshaft was connected to four forging hammers at the same time, and the cycle was up and down, the downforce of the forging hammers drove the upward force, and the power required was much smaller than that of driving a forging hammer.

However, after the craftsmen of the Silver Works Bureau experimented, the silver coins produced by cold forging still did not meet the requirements. This was mainly due to the uneven force caused by the offset problem of the mold.

In order to solve this problem, the craftsmen added a fixed platform to the outside of the mold. The fixed platform has three iron columns with a height of nearly 1.5 meters, which are connected to the load-bearing platform below.

The forging hammer above has added three holes, which just pass through the iron column, so that the problem of offset is solved.

After such a transformation, it took another month.

On the other side of the casting workshop, thin silver plates slightly thicker than silver coins began to be cast yesterday, and after cooling down today, large-scale trial production will begin.

Of course, hot forging of silver coins is easier than cold forging, but hot forging is easy to deform, and the requirement for silver coins is that they must be strong.

Moreover, cold forging has high dimensional accuracy, good surface roughness, good working conditions and high production efficiency.The only disadvantage is that the toughness is relatively low and secondary processing cannot be performed.

The reason why Zhu Zhanji insists on cold forging is because of these advantages. The silver coins produced by cold forging have higher precision and are not easy to counterfeit.

It is not easy for those unscrupulous businessmen to prevent it, which is conducive to the stability of the currency value.

After Zhu Zhanji arrived, the lifted waterwheel was put into the water again.The water wheel drives the connecting rod, and through the power ratio of the gears, it quickly drives the crankshaft to rotate.

Then, there was a bang, bang, bang in the forging workshop.

Several craftsmen lifted a silver plate and stuffed it in along the groove that was only a little wider than the silver plate. It can be clearly seen that four coin eyes were knocked out of the silver plate.

A craftsman waiting by the side immediately removed the one-dollar fan and replaced it with another one, stuck it into the groove, and then the forging hammer fell again.

Zhu Zhanji looked a little terrified, because as long as he moved slowly, his arm might be crushed.

Zhu Zhanji shook his head and said, "This won't work, it's too dangerous. This process must be improved."

Another craftsman waiting on the side quickly withdrew the four silver coins from the coin, handed the coin to the craftsman, and then replaced it in a cycle.

The picked out silver coins are placed in a basket next to the stamping table, and the craftsman holds a pair of pliers to pinch off the excess burrs at the vent holes on the back of the silver coins.

The silver coins are handed over to another person, and then the silver coins are checked to see if they are up to standard, and the qualified silver coins will be wrapped by workers with a piece of oiled paper in stacks of ten.

Then make up sixteen packs and put them into a special wooden box. A box of silver coins is ten catties.

There are four groups of craftsmen on one forging press, and one group stamps four pieces at a time, which costs 16 yuan each time.Moreover, the stamping speed is very fast, almost every ten seconds, a quarter of an hour, about ninety times, and 140 four silver coins can be die-cast.

This is just one die-casting machine, what if there are ten?10,000+ silver coins can be produced by continuous die-casting in one day.

Of course, this is just theoretical data. No matter how good the machine is, it will be damaged, the workers will be tired, and there will be mistakes.But based on basic calculations, there is no problem at all in producing 5000 yuan of silver coins with one machine a day and a few more groups of workers.

After a quarter of an hour of testing time passed, the machine stopped, and everyone else was still relaxed. Only the craftsman who replaced the money fan was out of breath because of nervousness and frequent loading and unloading of the money fan.

Zhu Zhanji picked up an alloy silver coin with only [-]% silver content and looked at it. Currently, due to the limitation of craftsmanship, the processing accuracy is of course not as good as that of later coins.But at least in this era, it is beyond the technology of any country.

Zhu Zhanji shook his head and said: "Although the forging problem of silver coins has been solved now, there are still many details that need to be solved. Only by solving these safety problems can large-scale production be possible."

-------------Chapter Dividing Line---------------

Zhu Zhanji observed for a quarter of an hour and mainly found two problems. One was that the four groups of people worked together, but because the forging hammers did not go up and down at the same time, they affected each other.

It can't be seen in a short time, but after a long working time, the staff may be in danger if they are affected by the team next to them.

This problem is easy to solve. You only need to add a partition between the forging hammers to solve the problem, or arrange the personnel to stand opposite each other, so that the impact will be less.

The second is the process of replacing the money fan, which must be improved.The weight of the forging hammer is [-] kilograms, and when it is inertial from a height of one meter, it can have a force of several hundred kilograms.Moreover, the top and bottom are all made of iron, and if there is a slight mistake, even if it is fatal, it is certain to be disabled.

Therefore, designing a process for replacing Qian Fan can make people feel at ease, because if something happens, it will not only affect morale, but also delay work.

This process is actually very simple. You only need to raise the money fan from the side and design a sliding card slot for the money fan. You don't need to take it from the top with your hands, but push and pull it from the side.

Zhu Zhanji made the request, and the craftsmen quickly understood, and the two problems could be solved within a few days.

Now that these two problems have been solved, the next step is naturally to prepare raw materials and open a bank.

There is no government-run bank, and relying on the annual tax money alone, I am afraid that the raw materials will not be able to supply the production.

The smelting of silver is much easier than steel, because the melting point of silver is only over 900 degrees, and ordinary furnaces can be smelted.

And it only needs to use steel plates to make casting molds to continuously produce silver plates suitable for forging.

The key is the raw materials, not to mention many, without a reserve of several million silver coins, it is impossible to promote silver coins on a large scale.

But now is the time when there is a shortage of money, and it will take some time for the tax money in autumn to be collected, so there is not much money from the court.

Zhu Zhanji doesn't have much money now.

His money was given to Zhu Di last year, and some money was taken back during the Chinese New Year, and it was invested in the construction of Xiama Bridge.

Now he can only hope that around November, the fleets going to Japan and North Korea will bring back enough money.

Therefore, the promotion of silver coins on a large scale will have to wait until around the new year at the earliest.

Prior to this, silver coins could be promoted in a small area in terms of salaries issued by the government.

It is estimated that it will take two years for the transition, and it will not be ordered until the next year, or later, to cut off retail silver transactions and switch to silver coin transactions.

In this way, the fire consumption that makes the people hate it can be removed.

However, it depends on whether the imperial court's Yinzhuang can be successfully opened.

This era is not the era when the national credit of later generations has been established. People believe in the country and the government more.

Now is the era of imperial power, the emperor seems to be aloof, but when it comes to interests, he is like a plague god, and no one wants to provoke him.

why?It's simple, because there is no sense of security!

The emperor can do whatever he wants, copy your home if he says, kill your people if he kills you, and let you put money with the emperor, who would dare!

But for banks, Zhu Zhanji will never allow private individuals to open them. Even if there are many private silver buildings now, they also do some bank business, but this is only for now. do it.

Allowing private capital to control the flow of funds in the country will only lead to one result in the end, that is, the instability of the imperial power.

If Zhu Zhanji is not a grandson, but an ordinary person, then he certainly hopes to realize democracy as soon as possible, or to be in power by himself.

But now he is the biggest vested interest, how could he poach his own corner!

Therefore, banks can only be opened by themselves. In the future, private banks must not be opened across borders, let alone be chained.

In this way, even local transactions can still go through the silver house, but cross-state transactions can only go through the imperial bank.
