The Weapon Tycoon Who Traveled to Great Qin

Shangwen made a heavy cross on the two characters "lumber". It seems that it is obviously impossible to use wood as a hydraulic press. Although the iron plate can be pressed to a certain thickness to a certain extent. But this thickness still cannot be resolved.

"Mr. Qin, do you think this is fine? Widen and enlarge the casting mold of the iron block. The weight is reduced. Maybe it can be pressed into a certain shape." Chen Da said.

"This." Shang Wen thought.

"Mr. Qin, I think this method works. In this way, the weight we require is less. It should be possible." A craftsman immediately thought.

Shang Wen is calculating this formula at this time, seeing everyone so positive. Then leave it to them to try it out, isn't it all right?

"Well, this method can be tried, but I have one suggestion. According to the current use of wood, it cannot meet our needs. Therefore, my suggestion is that those hydraulic cylinders should still be made of iron." Shang Wen Make a suggestion of your own. The use of wood is obvious. Pressure, the pressure you endure can't be withstood. There is also airtightness. Although the carpenter makes it very skillfully. But after all, the tightness is very poor, at best. This wood can be regarded as an experimental product. It can't be regarded as a kind of machine.

"However, I think everyone is so interested. You can study by yourself. I will write about the principle of the hydraulic press later. I'm going to the area to work on the air hammer and the adjustment of the drum machine. Come on, everyone." Shang Wen finally realized Something passed by what I said, so I ran away quickly.

The craftsmen involved in making the hydraulic press simply ignored what Shangwen said. Rather, re-discuss the production of this hydraulic press. This is the first time they have seen such a machine. A whole piece of iron can be pressed to such a degree. And the manpower and time used are very small. This is very rare. Feel very valuable. Therefore, the craftsmen began to sit down and discuss in detail.

Shang Wen doesn't have that much effort. I am responsible for a large engineering system. If you only rely on one person, you can't even bring Qin into a huge industrial era in your life. Unless, rely on these people. These people are just busy with production and rarely have the opportunity to try. Now give them a chance. Also show them the schematic drawings. If you don't understand, explain a little bit. Let them do the rest. If you do everything yourself. I must be exhausted.

Thinking of this, Shang Wen walked to the other side of the machine tool. Stand aside and explain for a craftsman to connect the driving rod of the steam engine to that part. The drum relies on the continuous rotation of the drive rod. How come the made things come and so on. The craftsman nodded as if he understood. Shang Wen couldn't take care of it either. Hurry up and leave. Draw some designs into atlases for those craftsmen to see.

"Mr. Qin, Mr. Qin." Chen walked over with a few wooden sticks in his hand.

"Mr. Qin, this is the pencil you mentioned. I'll make it for you." He took the wooden stick in his hand to Shangwen.

Shang Wen took Chen's wooden stick and looked at it carefully. So thick. It's almost the same caliber as the bullet I made. Moreover, the refill is very thick. The length is much longer than that of ordinary pencils. But think about it, this guy probably hasn't seen it before. Forget it. Don't be so strict. Being able to make this thing is much better than drawing with a brush every day. Besides, it is so thick that it can almost be carried with you.

"Well, not bad." Shang Wen praised.

"But it's still a bit big, you see if you can discuss it with the carpenters. The brush is as thin and long as it is." Shang Wen said while holding a rough pencil.

"This, no problem. I thought about it at the beginning. But it's harder to make, so I just did it. But in the future, this thing, yes, a pencil. It must be made so fine." Chen Yong said.

"Okay, I'll use it first. Go ahead, and I want to draw some drawings." Shang Wen shook the pencil in his hand and said.

"Then, let's say goodbye. Mr. Qin." Chen Yong saluted.

"Farewell." Shang Wen also saluted. Then quickly left with a pencil.

Hydraulic press is a machine that uses liquid as working medium and is made according to Pascal's principle to transfer energy to realize various processes. The working principle of hydraulic press. The schematic is as follows. The areas of the large and small plungers are S2 and S1 respectively, and the hydraulic pressure on the plunger is F2 and F1 respectively. According to Pascal's principle, the pressure of a closed liquid is equal everywhere, that is, F2/S2=F1/S1=p; F2=F1(S2/S1). It represents the gain effect of hydraulic pressure. Like mechanical gain, the force increases, but the work does not gain. Therefore, the movement distance of the large plunger is S1/S2 times the movement distance of the small plunger. Of course, Shang Wen would not use the English letters that should be. Shangwen directly uses A and B to replace English letters. Shangwen was afraid that the craftsmen would not understand. Specifically marked below. Wrote a long note.

"call". This thing is finally finished. Shang Wen threw away the pencil in his hand, and then stretched out his arm. Not to mention, drawing with a pencil is much faster than drawing with a brush. And not afraid of making mistakes, even if they do. You can wipe it off vigorously, or look for sawdust to wipe it off. It is better to use breadcrumbs. But came to this world. Shangwen has not eaten a meal made of wheat, which is basically millet. Or it's meat. Shang Wen has become a vegetarian, and if this continues, he has to lose weight.

"Qin·····Qin·····" a kind of crushing stutter came. Shangwen hurriedly put his complaint aside, and invited the stuttering Han Fei in.

"You don't need to talk, let's talk with a pen, so hurry up. Please come in." Shang Wen completed the following actions in a series. Han Fei didn't mind Shangwen's words either. After all, it would be impolite to say a person's flaws in front of a person.

"I'm here to ask Mr. Qin a few questions." Han Fei picked up a brush on the table and wrote quickly.

Shang Wen looked at it. I can barely recognize these words myself.

"You said." Shang Wen wrote.

"Is there any other content in the book you gave? I found that the book is a bit incomplete." Han Fei wrote.

"Yes, yes. I'll copy it to you later." Shangwen really didn't want to write it, it was too much trouble. Speak directly.

Han Fei nodded.

"Great, can you hurry up." Shang Wen saw these words written on the paper. Some collapse. This guy really doesn't think about other people's feelings. I'm so busy. How can I copy books for you?
