Zhao Zhikuan chose the site for the new weapons factory on the west bank of the Nandu River, which was later to be known as Baisha Park. He chose this location because it was relatively close to the future steel plant, and it was located at the mouth of the Nandu River, so transportation was also very convenient. There is another point.

Just keep it secret. This place is far away from the main island. The weapons factory needs to experiment with some weapons, which will naturally make noise. Choosing this place can avoid attracting the attention of outsiders.

But it's not without its disadvantages. It faces the sea and is far away from the main island. It is easily attacked by enemies on the sea. However, Haidian Island is so big and every place has been planned. Zhao Zhikuan had no choice but to choose the address here.

, As for the enemy’s problem, it’s up to Zhao Heng to solve it.

The weapons factory is very close to Zhao Heng's new army camp, only one mile away. When passing the military camp, Zhao Heng sent his newly recognized brother Zhao Xiang back to the military camp and handed it over to Zhang Guozhu for recruit training. After the piracy incident, the new army has begun to expand its army. Zhao Fuxiang

With a stroke of a pen, two hundred people were directly added, and three months of recruit training are now underway.

Zhao Fuxiang was really disappointed when he came to the weapons factory. What kind of factory is this over there? It's not even a processing workshop, it can only be regarded as a processing point!

The factory occupies quite a large area. A total of hundreds of acres of land have been leveled. The trees have been cut down and the roads have been leveled. The infrastructure is quite good. However, there is a small grass shed erected on the huge flat land.

There are also two newly built wooden houses. When Zhao Fuxiang saw that the wood of the wooden houses did not even have the bark removed, it was probably because they were in a hurry and they were simple.

Zhao Fuxiang looked at this simple factory building, pulled his son and asked in a low voice: "Son, this is the weapons factory run by your grandfather? I think Blacksmith Wang's blacksmith furnace is more advanced than this!"

Zhao Heng chuckled and shouted loudly: "Grandpa, my dad said your weapons factory can't keep up with Blacksmith Wang's blacksmith furnace!"

In the distance, Zhao Zhikuan was leading a few apprentices around an object to study something. After hearing what Zhao Heng said, Zhao Zhikuan turned his head and glared at Zhao Fuxiang.

Zhao Fuxiang cursed in a low voice: "Boy, don't you feel comfortable if your father doesn't get beaten?"

After Zhao Fuxiang finished speaking, he trotted over to Zhao Zhikuan and said with a smile: "Dad, that boy Zhao Heng just talked nonsense. This weapons factory you built is really high-end. I think my son will have no problem building a rocket to go to the sky in the future!"

Zhao Zhikuan glared at Zhao Fuxiang, and then said: "I really want to build a rocket, but you give me iron materials! The total transportation of less than 10,000 kilograms of iron materials is only enough for me to use for three months!"

Zhao Fuxiang just delivered nearly 8,000 kilograms of iron yesterday, but now he heard that it was only enough for a few months. Zhao Fuxiang looked confused: "Dad, you spend money countless times faster than your son makes money.

My son has already sent people to mine, and it is estimated that we will be able to produce iron ourselves in two months, and we will definitely meet your needs by then!"

Eight thousand kilograms of iron may seem like a lot, but in fact it is only about forty tons. Zhao Zhikuan uses more than five hundred kilograms of pig iron for one boiler. Adding in the steam engine, a complete power source requires one thousand kilograms of iron.

, and this does not include the ball mill of the big iron-eater, which can't be loaded without three thousand kilograms of pig iron!

Zhao Zhikuan also knew that it was really difficult for his son, so he didn't say anything, waved his hand and called Zhao Heng over from behind Zhao Fuxiang, and said with a smile: "Boy, what do you think this is?" After speaking, he pointed at the big guy in front of him.

.

Zhao Heng looked at it

(This chapter is not finished, please turn the page)

This thing made of wood looks a bit like the machine tools on TV, but there are some differences. The extra beds on TV are full of various parts and instruments, giving it a tall look, but this thing in front of you looks a bit like feeding cows and horses.

manger.

Zhao Heng knew that his grandfather would not build a horse feeding trough here for no reason, so he asked tentatively: "Grandpa, is this a machine tool?"

Zhao Zhikuan laughed loudly and said: "Yes, it seems that you are smarter than your father. This is the machine tool I developed, old man. How about calling it Hainan No. 1 for the time being?"

Zhao Fuxiang looked at this big guy, which was three meters long and one meter high. It didn't look like a machine tool, but rather looked like a trough for feeding horses. However, he didn't dare to tell the truth, so he could only compliment him: "Dad, you actually developed this invention."

A machine tool? It’s so powerful, I think this machine tool should be called Zhikuan No. 1!”

Zhao Zhikuan laughed: "You kid, stop flattering me, this is not developed by me, it's just a copy of the domestic C618 machine tool!"

In fact, Zhao Zhikuan is bragging when he says he imitates. According to Zhao Zhikuan's current strength, he cannot imitate any later machine tools, not even the C618 machine tool of the 1950s.

The c618 machine tool was copied by the Shenyang Third Machine Tool Factory in 1954 from the c618 machine tool provided by the Soviet Union. After the successful imitation, it was also named the c618 machine tool. The center height of this old machine tool from the Second World War is 180 mm, the maximum cutting diameter is 360 mm, and the maximum cutting length

1800 mm is enough for processing ordinary parts, but it is not suitable for processing some medium and large parts.

Although this kind of old machine tool has backward technology and low processing accuracy, it was used in China until the 1980s because of its durability. After the Shenyang Machine Tool Factory introduced advanced European and American CNC machine tools, it slowly ceased production. However, in some small towns and villages

You can still see this kind of honest machine tool in the factory.

Zhao Zhikuan completely copied the illustrations in the dual-purpose talent manual. All precision components could not be copied and had to be abandoned. However, the main spindle box, feed box, slide box, tool rest, tailstock, feed rod, and lead screw of the machine tool

The main components such as the machine body and the bed are still there, but the electric motor is replaced by a steam engine to provide power. Therefore, a large flywheel is installed in front of the main spindle box and is connected to the steam turbine on one side with a belt to provide power to the machine tool.

Next to the machine tool is a steam turbine workshop. Power is transmitted from the steam turbine through a belt, and then transmitted here to drive the movement of the machine tool.

Zhao Fuxiang looked at the huge steam turbine, and then at this simple machine tool made of wood and iron, Zhao Fuxiang asked: "Dad, why can't we use a motor? Do we have to use a steam turbine for transmission? Didn't you say that a generator is easy to develop?

?”

Mentioning his old line of work, Zhao Zhikuan sighed and said: "The principle of the generator is very simple. It can use water, wind, or steam. But how do you transmit power after it is developed? The wires need to be insulated. Although paint can be used for short-distance insulation.

But long distance is not possible at all. We must find suitable insulating materials to use electricity on a large scale! Although the current steam turbine looks bulky, at least it is what we can currently produce in large quantities! But I am now developing a new generation of double-action type

A steam engine is much smaller than a steam turbine!"

In fact, the energy conversion ratio of the steam turbine is much higher than that of the double-action steam engine, but due to its large size, no matter how rich the Zhao family is, they cannot install one in every factory, so the development of a double-action steam engine has become inevitable.

(This chapter is not finished, please turn the page)

.

Zhao Fuxiang also knew that it was a bit difficult for the old man. Although Zhao Zhikuan had hundreds of years of experience, it was too big to ask an electrical engineer to work on a steam engine. Zhao Fuxiang had no choice but to comfort him: "Dad, I will follow your instructions."

If you don't have the ability to develop that double-action steam engine, we're just waiting for your good news!"

Zhao Zhikuan glared at Zhao Fuxiang without saying anything. At this time, one of Zhao Zhikuan's apprentices came over and said respectfully: "Master, we have already checked everything. Please go over and test the machine!"

Zhao Fuxiang was so envious when he saw his father's disciples being so respectful. He had many subordinates now, but there were only a few who could serve as their father. Thinking of this, Zhao Fuxiang suddenly felt like he had adopted several godsons.

Needless to say, my father now has several apprentices under me. As for my wife Sun Jing, after the pirate incident, she also recruited a few yellow-haired girls as apprentices. Now I have no one except Fan Jian.

One person follows.

When Zhao Fuxiang was thinking whether he should learn from Zhu Yuanzhang's search for 108 godsons, one of Zhao Zhikuan's apprentices ran over with a one-meter-long wooden stick. Zhao Zhikuan fixed the wooden stick on the clamp of the machine tool, and according to the current

Technology, of course this simple lathe cannot be equipped with advanced four-grip heads or six-grip heads. It can only use the three-grip head from the First World War, but the accuracy of the First World War is enough.

Clamping the wooden stick on the fixture, Zhao Zhikuan first adjusted the tailstock so that the wooden stick was in the center position, then adjusted the screw and attached the cutter head to the wooden stick. The most difficult part to manufacture on this simple machine tool is this

The light rod and lead screw of machine tools transmit torque to move the tool holder. The light rod and lead screw are two steel columns with spiral patterns on the surface. The movement of the tool head is controlled through the sliding crate. Of course.

Zhao Zhikuan has not yet been able to build a six-axis machine tool. The current one can only move in two axes, which means it can control the movement of the cutter head up, down, left and right. Other six-axis five-linkage CNC machine tools can probably only be thought about in dreams.

After Zhao Zhikuan adjusted the cutter head, he motioned to the apprentice on the side to connect to the steam turbine. After a clanging sound, the flywheel on the head of the machine tool was connected to the flywheel of the steam turbine through a belt. The power was continuously transmitted to the spindle box. Although the belt

The transmission will lose some power, but this soft connection can omit the transmission gear. The diameter of the flywheel of the steam turbine is two meters, and the speed is about one hundred revolutions per minute, while the diameter of the flywheel on the machine tool is much smaller, only fifty centimeters.

, after transmission, the rotation speed of the lathe spindle is about 400 rpm, which is still within the controllable range of natural lubricating oil.

As the spindle rotates, the wooden stick fixed on it also rotates. Zhao Zhikuan taps it lightly with the mallet a few times to make the stick rotate more smoothly, and then starts to adjust the light lever so that the knife head starts to contact the wooden stick.

After a squeaking sound, pieces of sawdust fell one after another, and Zhao Zhikuan's machine tool was considered to be running successfully.

With the movement of the cutter head, a straight wooden stick appeared in front of everyone. After the machine tool stopped, Zhao Zhikuan took off the wooden stick that was turned into a three centimeter diameter. Zhao Zhikuan held it in his hand and showed off: "How is it?

Not bad, right?"

When Zhao Zhikuan's disciples saw this novel thing, they all cheered: "Master is so awesome!"

Looking at these sycophantic disciples, Zhao Fuxiang asked inappropriately: "Dad, what is the use of this thing you made? Are you mass-producing mop rods?"
