Rebirth of the 80s New Farmer

The problem of the piston should not be difficult to solve. Once it is finalized, it can be customized and processed by a professional manufacturer of pistons. There are such factories in Bohai City and Shenyang.

The cost of manufacturing in a professional factory is lower than that of making it yourself.

Chapter 7 and Chapter [-] are all about manufacturing madmen (end of the fifth update)

Wan Feng listened to Master Luo Zhongxing's introduction to the engine.

"This engine has a total of 560 parts, of which 560 are low-difficulty parts, 890 are medium-difficulty parts, and there are only more than 100 really difficult parts. Although they can be imitated by hand, the speed It’s too slow, and we can’t build a few motorcycles a month.”

"Of course we can't rely on our own production. We can't do everything professionally. We can't control the production cost by ourselves, and we can't enter the market at all. Therefore, we have to outsource all the parts with low processing difficulty to professional factories. Do it, just leave a few key things and make it yourself, and then we can get the parts back and assemble it, which will not only speed up the production schedule but also greatly save costs.”

Luo Zhongxing nodded: "Then we will specialize in the production of a few of the most difficult things, so that others cannot produce them. Even if others want to imitate, they must overcome these few technologies."

This is also a trick to guard against lazy people. With the technical content of the 50 engine, it is really not difficult if someone really wants to tinker with it.

"How long did Unit One burn when it ignited?"

"The No. 15 unit ignited twice, the first ignition worked for one minute and 5 seconds, and the second ignition worked for [-] minutes."

"You put out the fire yourself?"

"No, we found the problem and took the initiative to put out the fire, and then inspected it."

"What problem did you find?"

"The first time the organism was overheated, we found the cause and ruled it out, and then carried out the second ignition. After working for 5 minutes, there was a problem with the carburetor, which has now been ruled out."

"So now we should do a third run to see if it works for 10 minutes and if there are any issues."

Engine No. [-] was started for the third time, and the engine made a chug-chug sound.

Technicians stare nervously at the working engine.

1 minute, 3 minutes, 5 minutes...

This time the engine worked longer than the previous two times, until the engine worked for about 8 minutes, and the body overheated again.

Bank of China immediately gave the order to shut down.

This time it took a long time to find out the cause. After nearly a morning of unremitting efforts, I finally found out the cause of the overheating phenomenon: the problem occurred on the piston ring.

Although the specifications of the piston rings grinded by Mr. Luo meet the standards, the matching of metal materials is not correct, and overheating and deformation will occur after a long working time.

They are not specialized in the production of this thing, which requires a professional counterpart.

"We need to find a professional manufacturer to solve this problem." This is Luo Zhongxing's suggestion.

At that time, there were manufacturers producing piston rings, one in Liaoyang, and the other in Shijiazhuang.

The piston rings produced by Liaoyang manufacturers are low in cost, but their wear resistance is not good.

The piston rings manufactured in Shijiazhuang are of high quality and durable, which is a common choice for many engines today. The piston rings for the single cylinder 195 of Wahou Machinery Factory are produced by this factory.

However, the Shijiazhuang factory definitely does not have the piston rings used in this 50 engine, because this thing is only produced by the Jialing factory now, and they cannot go all the way to Shijiazhuang to order piston rings.

This requires Shijiazhuang to make new molds. When people don't know the scale of the product, they may not be able to make it for them.

"Master Luo, it seems we have to go to Shijiazhuang."

Wan Feng decided to go to Shijiazhuang with Master Luo in person. At this time, he had to act. When he had money, he had to show the power of money. By the way, he would go to Qindao to do some private affairs.

The motorcycle engine was temporarily put aside, Wan Feng pushed Luan Feng's motorcycle over, and a technician took it over to replace the front wheel.

"How about the 1105 and 1115 engines?" Wan Feng asked the two single-cylinder diesel engines with 25 and [-] horsepower.

"It has completely passed the national inspection, but we don't know what it should do now. Only a small amount has been produced and it has been technically sealed." Xiao Dexiang explained.

"Don't worry, let me think about it. What should I use them for? After the motorcycle engine is successfully researched, our next step is to study the four-cylinder engine."

Those two single-cylinder high-horsepower diesel engines are of course used on large-tonnage agricultural tricycles.

However, if this kind of agricultural tricycle is put into production, it will definitely have an impact on the four wheels. The supply of four wheels in the machinery factory is currently in short supply, and there is no need to produce large-tonnage tricycles for the time being.

Make a technical reserve first and put it aside for two years.

Anyway, those in Dongshan Province don't know where the whirlwind is blowing.

"According to the working principle diagram you drew, we are already researching and casting the body, and we have bought all the parts that can be purchased. We are going to produce the parts that are not for sale. gone."

Wan Feng was once again shocked by the work enthusiasm of these people.

These people are still working on four-cylinder diesel engines at the same time as they are working on 50 engines?What kind of spirit is this?

Is this the spirit of wholeheartedly serving the RMB...serving the people?

At this moment, Wan Feng suddenly felt that it was time for his mother to look for her second aunt and brother, and it was time to come back.

He is inspired by the working environment here and the enthusiasm of the people.

If he hadn't been thinking about Maozi's talents and some technologies he wanted, he would want to come back now.

This is a place for people to do something.

The front fork and front wheel of the motorcycle were quickly replaced, and Xiao Dexiang rode it out for a lap. When he came back, Wan Feng was already researching the electric fan.

He is working with the people in the technical department to study how large a coil should be wound as the starting source of the fan.

There are many people and strong strength. It doesn't take long to wind the coils and make the fan blades. A fan without outer packaging is successfully made, and the fan starts to spin when it is connected to the power supply.

Although the workshop can keep out the shade, it can't keep out the high temperature. With such a thing, everyone moves in front of the fan to make do.

"This thing is better, it's so easy to produce, why don't we produce some and sell it?" a technician asked.

Wan Feng said: "I'm afraid it will be too late this year. It's already the end of July. It will probably be autumn when we produce something that passes the inspection. Next year we can set up a special electrical factory to produce these things. Now you are free to study and play, but If you want to sell it, an electric fan that can’t shake your head, set a timer, or adjust the wind speed won’t work.”

"That's not a problem. If you don't shake your head, we can make a small mechanical device to achieve it. As for the timer on the washing machine, wouldn't it be over?" Another technician who had seen the washing machine suggested.

"Should we also study the washing machine, as if it's nothing special to have a motor under it."

It's okay if the technician didn't suggest it. Once he suggested it, these people started thinking about the washing machine again.

Wan Feng quickly took the fan that looked like a skeleton frame and rode his motorcycle back home. After sitting here for a while, they might not know what to make again. These guys seemed to have become manufacturing madmen.

Chapter 7 The Smaller the More Enchanting

When Wan Feng returned home on Luan Feng's motorcycle, he began to think about how to put a coat on this ugly electric fan.

He drew a few patterns according to the shape of this table fan, and then handed over the task to his uncle.

Anyway, he has an injection molding machine, as long as he makes a mold, pours out the shell and installs it, isn't it all over? What a big deal.
