Chapter 153 Sign in Once in the Workshop
The master talks and the apprentice breaks his legs.
Luo Cheng is like this in the workshop now. He is doing small research. In a word, he is dismantling this and that. Wang Cheng and his apprentice spent a long time tinkering with screwdrivers, screwdrivers, adjustable wrenches, socket wrenches, all kinds of small tools. This made Luo Cheng really miss the electric repair tools of later generations. Just bring a hand drill or something like that, especially a pneumatic cannon, which is the kind used to install and remove tire screws, also called a pneumatic wrench. It's not fast to disassemble and install.
After thinking about it, Luo Cheng suddenly thought that this was not actually a big thing. Could he get it by signing in with the system? Just like when the system signs in in the forest, if it doesn't give you a wild boar, it will still give you a rabbit or a mouse.
Luo Cheng was reluctant to sign in at the auto repair shop at first, mainly because he thought it would be boring to get ordinary tools. The repair shop has them all, and the repairman can just apply directly and get a set. And you can't explain how you got the advanced electrician's tools. But things are different now. Now we even build our own cars. If you really sign in and get a power tool, you can also take it apart and try to imitate it. If you succeed in imitating one, you will become an equipment processing factory in the future.
"System, sign in."
"Sign in successfully and obtain items, including a hand hammer, a screwdriver, a small hacksaw, a hydraulic jack, and an adjustable wrench."
Sure enough, Luo Cheng was a little disappointed. There were all tools in the factory, but the tools in the factory were public. The ones Luo Cheng signed in were personal. However, these things would not be too wasteful. They should be kept at home. Sometimes they are at home. Things can be repaired if they are damaged.
None of them are electric tools. In the eyes of the system, do hand drills and the like exceed its specifications? It doesn't seem to be the case. Last time I signed up for a hair dryer. Although the hair dryer is cheaper, it shouldn't be the limit. But if you keep trying to sign in at the repair shop workshop, if you can't sign in for big things, it's probably because some of the repair tools are useless.
In the grain store, even if there is only one variety in the sign, as long as it is food, it doesn't matter. This is not food, and you don’t need it on a daily basis. It might be too wasteful to sign in.
Hey, ~Hydraulic jack! Luo Cheng suddenly came to his senses. This would be the most common jack in later generations, but currently there are only screw mechanical jacks in China.
Yes, the principle of a hydraulic lift is the same as that of a hydraulic jack. I have already made a hydraulic booster pump and hydraulic shock absorber, but I have forgotten my own professional repair tools.
The hydraulic shock absorber is a form similar to a pump, and the hydraulic shock absorber also relies on the input hydraulic pressure to lift objects based on the pressure area.
Unfortunately, it is impossible to set up a dedicated parts factory for just one hydraulic jack. The demand for this thing is so low that it can't be used in large cars, so it is repaired directly under the car. There is no need to have one for each car. Drivers who can do simple repairs in this era usually just ask a few people to lift it up and put some bricks on it. Unlike later generations of automobiles, spare tools do not have jacks.
At best, this thing will become a product produced by the machinery factory, and the output must be controlled. If there are too many, it may not be used. A car repair shop can have a few, and it feels like it is fine. But when it is produced, it must be sold to the whole country. In just one city, it feels like If you design a production lathe, you will lose money.
But there is one thing. There is a product that has exactly the same principle as a hydraulic jack. It is low-cost to make and has a huge market. It is absolutely possible to build a large factory specifically to produce this, and there will be no delay in building forklifts in the future.
Luo Cheng was confused by building a cube car, and he always focused on the car. But I forgot that there are two types of forklifts. There is a thing called a manual forklift. The shape is the same as the forklift frame, but it has a few wheels underneath to push it. The main structural principle of such a forklift is Jack principle.
With a manual forklift, they didn't need to work so hard to move things just now. Moreover, the production of forklifts will also drive a related industry and create labor jobs. That is the lumber factory. This manual forklift is pushed and pulled on the ground. My chassis is very low. Even if it can be raised, it is very limited, so I need a matching pallet to use it. These pallets are made of wooden shelves. This forklift is manufactured by Come out and sell them as a set.
"Team Leader Luo, I installed everything you requested and disassembled it."
While Luo Cheng was still deep in thought, he was interrupted by Wang Cheng. The jack and gearbox had been completely disassembled.
"Cut off the screw rod, and make two 50-centimeter and two one-meter tubes out of the square tube from the last time I built the car."
"Team Leader Luo, this screw rod and the jack are all useless."
"How can it be scrapped? It can still be used after welding it. But if it is scrapped, one of the screws must be scrapped. One of the matching screws will be cut off later. It's okay."
Luo Cheng said, it won't work if it's cut off, but it won't work the same if it's welded back. Wangcheng is not changed at once, but if a section of the screw is cut into the center and welded on, it will no longer be the original line, and one will definitely be scrapped.
When Wang Cheng heard what Luo Cheng said, he didn't say much. Even if Luo Cheng didn't answer, he would do what Luo Cheng said. But I felt in my heart that Luo Cheng was wasting things by doing this, so I couldn't help but ask.
Luo Cheng ignored them, thinking that the factory director was away now, there was no one in his office, and there was a set of repair tools in his office. So I let Wang Cheng and the others take care of it first, while I sneaked into the factory director's office alone.
Taking out the hydraulic jack from the system, Luo Cheng quickly found tools to dismantle it. Then I found paper and pen, and started to draw the structural principle diagram of the manual forklift while thinking about the internal structural principles of the hydraulic jack.
Although you don’t need to refer to the hydraulic jack, you can slowly analyze the general structure of the hydraulic jack, but you know that there is a big difference between the principle and the manufacturing. At least the design must be adjusted step by step, and then the manufacturing must be adjusted to the maximum rationality. data ratio.
For the same hydraulic space ratio, the pressure is completely different. At that time, the jack you build can be considered a success if it can lift one ton, and it can be considered a success if it can lift two tons. But with the same construction principle, how to specifically create the maximum value is not Luo Cheng's strong point.
Now that there are ready-made things, just follow the proportions and structure. The forklift will follow the structure of the jack and the impressions of later generations.
The components are drawn on white paper one by one, with reference objects, so it should not be too simple. When this thing was built, there were no road inspection requirements at all, and the technical content was not high. Now Luo Cheng had a little understanding of some of the rules for planned production.
For example, after analysis, for fear of overproduction, if you set a quantity of one thousand for something, and you can only produce 500, that means the output is insufficient. If the output is insufficient, other places can build such factories to produce such products. The planned production volume is one thousand. You can produce two thousand, but you can only do it according to the plan. You are afraid of wasting too much, but other places and cities will not produce it again.
They are all state-owned enterprises, and they will open branch factories even if the output is not enough.
Therefore, Luo Cheng understood that if this manual forklift, which did not have much technical content, was to be built, local units should take the greatest measures to solve the employment problem of urban youth.
