Siheyuan starts from a better life

Chapter 371, Electric Fan (5K)

"Let's go to Friendship Mall." Jiang Sirui suggested to Jiang Yan as soon as he got in the car after work that day.

The summer in Forty-Nine City is really difficult. Jiang Yan has been hiding in his own space these days, or getting some ice from the space and putting it in his room.

It's okay for me as a man to go shirtless this summer, but it's extremely unfriendly to girls.

Feeling that he was careless, Jiang Yan thought about starting to make amends. You don't have to think about air conditioning or anything like that.

my country's first air conditioner was born in 1954, which was a milestone in the air conditioning industry.At that time, our country's engineers successfully manufactured the first air conditioning equipment after years of hard research and development.

my country's first air conditioner used mechanical air conditioning technology.Mechanical air conditioners use mechanical equipment to cool and circulate air, including key components such as compressors, condensers, and evaporators.This air conditioning technology was very advanced at the time.

However, this air conditioner is mainly used in large public places, such as government agencies, large enterprises and institutions, etc.As for its appearance in the homes of ordinary people, it will probably have to wait until reform and opening up.

The next best thing is to buy an electric fan. The key is that this electric fan is also a rarity in this era.

Jiang Yan had asked his director before to see if he could get a ticket for an electric fan. After getting a negative result, he thought about whether there was one in the friendship store.

But even if there was a fan, Jiang Yan would not buy it if he had no other choice.

What can you say about the electric fans produced in this era?The quality is quite good, and the style is just that. The key is that the thing is quite heavy, and almost all of it is made of steel.

Jiang Yan remembered that in his previous life, he had a brick and stone electric fan produced by his father in the 70s. It was older than him at that time. The key is that this thing was still functioning during his time travel, and the quality was quite good.

This fan is too heavy and difficult to carry, especially when Jiang Sirui is using it alone.

Jiang Yan just thought about it. If he didn't like it in this friendship store, he wouldn't mind making one.

Jiang Yan's eyes lit up when he thought of making an electric fan. He couldn't help but pat his thigh.

"That's right! You can make it yourself! The technology content of this thing is not high. If you make this novel-looking electric fan yourself, you might be able to exchange money at the Canton Fair!"

He went back to the courtyard to pick up He Yuyu, who had already finished school. He had promised her to take her to the Friendship Store before, so it was better to hit the sun on a different day. Jiang Sirui agreed, so he went back to take her, and after taking He Yuyu, he got in the car. Then he drove to the Friendship Store.

The Friendship Store in Sijiucheng is located along East Chang'an Street, on the bustling Jianguomenwai Street, adjacent to the embassy district and the CBD Central Business District. In future generations, this is a place where every inch of land is at a premium.

At the door of the Friendship Store, Jiang Yan showed his ID. Only after seeing his ID did Jiang Yan and the three of them get let in.

After entering, I realized how big this place is!

Steel Jiang Yan read the introduction of Youyi Store at the door and learned that the Youyi Store in Sijiu City has four floors and a business area of ​​more than 9000 square meters. The environment inside is spacious, bright, comfortable and elegant.

Jiang Yan was okay. He had gone to many high-end places like this in later generations, so he was not surprised. However, Jiang Sirui and He Yuyu had never seen such a clean and bright floor before. They could only stand at the door in a daze, not daring to say anything. Walk inside.

"Let's go! What are you doing standing still!" Jiang Yan pulled the two of them. Only in this climate did the two of them come back to their senses and followed Jiang Yan inside. However, even though they entered, they still followed Jiang Yan closely. Never leave.

"Brother Jiang Yan, I heard that you need foreign exchange coupons to buy things here." Jiang Sirui whispered after coming in.

"Yes, I'm bringing it with me! Just feel free to buy it!" Jiang Yan patted his pocket with a relaxed look on his face.

In addition to the 1000 yuan foreign exchange coupons given to me by my superiors as a favor, I now have 600 yuan left, which is equivalent to two years’ salary of an ordinary worker. As long as I don’t buy anything big, it’s enough. .

Jiang Yan took the three people around on the first floor. Now Jiang Yan had his eyes opened. The Friendship Store mainly deals in jewelry, diamonds, gold and silver jewelry, jade carvings, cloisonne, carved lacquer products, fine porcelain, Classical furniture, four treasures of the study, antique calligraphy and painting, drawn yarn embroidery, blankets and silk blankets and other traditional Chinese handicrafts.

Jiang Yan stopped in front of a shop selling jade, picked up a green and transparent jade bracelet and looked at it.

He just didn't understand, and he knew just by looking at the green color that the value of this jade bracelet was so small that it would cost less than a million in future generations.

When Jiang Yan saw the price of the bracelet, he almost cursed.

Can you believe that such a good bracelet only costs 120 yuan in foreign exchange coupons.

And the milky white ones next to them look like jade bracelets and pendants made of high-quality jade. The most expensive ones are only 60 to 60 yuan. Those small pendants are even cheaper. A set of twelve zodiac signs carved from jade only costs [-] yuan. Yuan money.

Jiang Yan quickly calculated in his mind that he would be sorry if he didn't buy this thing since it was in front of him.

Under the dumbfounded look of the salesperson, Jiang Yan bought two pairs of emerald green jade bracelets, a set of zodiac pendants, some jade bracelets and some gadgets, which cost him almost 300 yuan.

The man led Guanyin and the woman led Buddha. Jiang Yan handed two identical ice jade Maitreya Buddhas to He Yuyu and Jiang Sirui.

"You two, keep these two carefully and don't let others know. They may be of great use in the future."

The two of them were a little confused about Jiang Yan's lack of answers, but girls all like these shiny things. Soon the two of them put Jiang Yan's words behind them and were chattering away with two jade pendants. discuss.

The second floor basically sells clothes and food produced by well-known domestic manufacturers.

These things are basically all kinds of fashionable "top-notch goods" that are not seen in the market. Many products were "special supplies" at that time: canned goods and white rabbit toffee from Shanghai Merlin, Western pastries from Qishin in Tianjin, and various products from Shengjing. Lao Lin, Suzhou's double-sided embroidery, Hangzhou's brocade, BJ Snow Lotus's cashmere sweaters and other things.

The two ladies couldn't walk after seeing these snacks. One of them held them with one hand, and looked at Jiang Yan with two pairs of big eyes.

It turns out that every woman is a foodie at heart, which is somewhat true.

Jiang Yan, who was not short of money, waved his hand, "Buy." As soon as Jiang Yan finished speaking, the two people cheered and rushed towards what they liked.

The snacks on the second floor were all bought for more than 50 yuan. The things were so big that they occupied the hands of Jiang Yan and the three of them. With no other choice, Jiang Yan could only go out and collect the things. Put it in the trunk of the car.

The third floor was basically filled with foreign food and clothes. Here Jiang Yan saw things like Coca-Cola, chocolate, whiskey, and Marlboro cigarettes.

However, this Coca-Cola is really expensive. A bottle of Coca-Cola costs three yuan in foreign exchange coupons. You must know that the current RMB to U.S. dollar ratio is 2.6:1. The foreign exchange coupons and RMB are one to one, which translates to about one dollar each for a bottle of Coca-Cola.

In the 60s, a bottle of Coke cost only about ten cents.

However, Jiang Yan still bought twenty bottles with a wave of his hand, and also bought some snacks, candies and chocolates imported from abroad.Fans and electrical appliances were on the fourth floor. Opposite the stairs was the place where TVs were sold. Jiang Yan curiously went up to take a look. This Toshiba TV set with a low price actually cost 800 foreign exchange coupons. This made Jiang Yan wonder. The words are a bit shocking.

However, it is basically useless to sell this TV now. There are not many TV stations in the country. It is completely a decoration.

There were several fans, and Jiang Yan picked them up and picked a fan from Hans Siemens. However, in Jiang Yan's eyes, this fan with a rather crude appearance cost Jiang Yan more than 130 yuan in foreign exchange coupons.

After all this, Jiang Yan only had less than 600 yuan left of the 100 yuan in foreign exchange coupons in his hand. However, seeing the two people looking satisfied, Jiang Yan felt that the money was well spent.Especially when Jiang Sirui knew that this electric fan was for her, her eyes almost melted when she looked at Jiang Yan.

"Let's give this to grandma!" Jiang Sirui looked at the fan and hesitated after being overjoyed.

"It's okay, you can use it! I bought one for my grandma before."

After learning that Jiang Yan's grandma was pregnant, Jiang Sirui happily accepted the electric fan Jiang Yan bought for him.

"Director, there is a project to make money, do you want to do it?" He went to work the next day.Jiang Yan came directly to the director's office.

"What project?" When he heard that there was a new project, the director who was working put down his work.

After the two alloys invented by Jiang Yan were taken away by the superiors, none of them were left to the research institute. Naturally, the director became resentful. At present, the progress of CNC machine tools is slow and the investment is huge. Now the institute only processes engines. The chassis is a lucrative job, but it will be a bit difficult to make ends meet in the long run. Even if Jiang Yan doesn't come to him today, the director will decide to have a good chat with Jiang Yan to see if he can get a more profitable project to subsidize it. In the place.

Na Cheng thought that he would doze off on his pillow, so he became so energetic when he heard about a new project.

After being asked by the director, Jiang Yan took out a stack of paper from a handbag he carried with him, handed it to Wang Honghai, and said, "Yesterday I took my girlfriend to buy an electric fan and found that the electric fans on the market are too big. Single, I went back yesterday and while I was free, I drew a picture. I want to make such a fan. The effect should be good. If possible, I would also like to take our fan to the autumn trade fair. Let’s see if we can sell it overseas.”

"Yeah!" Wang Honghai was shocked when he heard Jiang Yan's words. He had never seen an electric fan before, and there were many manufacturers producing electric fans abroad. Is it reliable to compete with them by himself?But regardless of whether it is reliable or not, this spirit is quite commendable.

Wang Honghai took the stack of paper with doubts in his mind, unfolded it and saw that the blades of an electric fan were drawn on it.If you look closely, you will see that this electric fan is different from the common electric fans on the market. The electric fans on the market usually have three pages. The leaves of the electric fan in Jiang Yan's drawing are five and the shape is slightly different. However, this The style looked quite innovative. Wang Honghai also noticed that the relevant shape parameters were written next to the blades.
"Why does this electric fan have five blades? Is it wrong in the drawing?" Wang Honghai asked Jiang Yan, pointing to the electric fan on the drawing.

Jiang Yandao: "This is an electric fan design that I came up with. The wind blown out by the traditional three-blade electric fan is relatively hard, and people will feel uncomfortable after blowing for a long time. The five-blade electric fan I designed The wind coming out is much softer and has the effect of a natural cooling breeze.”

"Director, look, I have added three levels here. The last three are three modes, so they can be adjusted as needed." Jiang Yan pointed to the drawing and explained to Wang Honghai.

Hearing Jiang Yan's explanation, Wang Honghai said in shock: "How do you know that the wind blown by your five-blade electric fan will be softer?"

Jiang Yan smiled slightly: "This is the result I calculated after calculation." Jiang Yan thought for a while and said: "There is a special formula for calculating this. Electric fans, as long as I know the wind direction and wind speed, I can calculate it. The force of the wind.”

"I designed this one. The curve of the leaves was accurately calculated. The wind blown by such good karma is softer than ordinary wind leaves. After calculation, under the same wind direction and wind speed, its wind force is much smaller. , I have also redesigned the engine of this electric fan. This engine is smaller in size, quieter than the engines currently on the market, and most importantly, it is also more energy-saving."

Wang Honghai laughed: "Hey! There are so many benefits. It seems that this thing is very promising. Can this thing be produced according to our current production capacity? Do we need to apply to our superiors to build a factory? In that case There will probably be people picking peaches, so we’ll just drink some soup and water.”

Hearing the director's somewhat disappointed words, Jiang Yan said, "I don't think it is necessary. To put it bluntly, the technical content of this thing is not high. As long as someone who understands some principles buys one and takes it apart, he will understand how to make and build one." The factory is completely unnecessary. '

"Director, you see, the processing requirements for this motor and fan blades are relatively high. We produce them in our own workshop. We can completely outsource things like this base and have them manufactured by other factories. We As long as we strictly control the quality, we will assemble and sell them in a unified way."

"Well, this method is good. It not only saves production efficiency but also creates value for brother units. I think this thing is okay. We have a meeting in the afternoon and we will discuss it in detail. But are there any difficulties in the production process?"

Hearing the director's question, Jiang Yan thought for a moment, then pointed to the drawing and said, "The mold for making this fan blade requires a segmented machine. I have no way of doing this. The factory director may need to coordinate."

"This is not a problem. I have a good relationship with Lao Yan. They specialize in producing equipment for the navy and have large-scale free-range machines. I will contact him in the next few days to see if he has time and ask him to help. busy."

"Director, how many tons does their machine have?" Jiang Yan asked casually.

"The forging machine at Lao Yan's side has a pressure of 1000 tons. It is the equipment that Mao Xiong assisted before. Let me tell you, they are quite nervous. If you are not an acquaintance, you can't use it at all."

"1000 tons?" Jiang Yan muttered, but Jiang Yan didn't listen at all to what the director said later.

Seeing Jiang Yan's expression change, Wang Honghai said, "Why is there too much pressure?"

Hearing the director's words, Jiang Yan was a little dumbfounded. This was such a big deal. This was not good enough at all.

Jiang Yan thought for a while and said, "The director's pressure is not enough. I have calculated that our mold needs at least a 2000-ton forging machine to forge it. It would be more enjoyable if we could use a [-]-ton machine to forge it."

"What the hell, 1000 tons is not enough," Wang Honghai asked Jiang Yan with some confusion.

"Not enough." Jiang Yan nodded seriously.

"Director, you can see that after the fan changed from three blades to five blades, the blades became narrower. To achieve the same strength, the steel plate is required to be thicker. In addition, the shape of the blade surface I designed is more complicated than the original one. After calculation, It cannot be formed using 50 tons of pressure stamping, and the pressure must be increased to 200 tons."

"Furthermore, the molds for ordinary fan blades are made of cast iron, which is not a big problem under a pressure of 50 tons. But now after the pressure is increased to 200 tons, the molds can't bear it. According to Seiko's calculations, one or two hundred such molds can be made The blade and mold will be damaged. I made preliminary calculations. If the punch pressure is 200 tons, the pressure of the forging mold must be 2000 tons, so that the mold can not deform under high pressure."

"Oh, that's it." Director Wang nodded after hearing Jiang Yan's explanation.

Wang Honghai said: "Lao Yan does have a 2000-ton die forging machine, but now there are many tasks, almost full capacity production, and it is impossible to free up machine time for you to use."

After saying this, the director thought for a while, and then said: "The largest segment machine in our country is a 5000-ton forging machine produced in the Czech Republic. It is currently in the Jiangnan Shipyard, but that thing is usually not available to you. "

Jiang Yan only realized when Wang Honghai said this. At that time, only a few countries in the world had 6000-ton hydraulic presses. Only the No. [-] Heavy Machinery Factory in China had a [-]-ton hydraulic press. This was the latest and heaviest machine in our country.

On February 2 this year, my country held a groundbreaking ceremony for a 14-ton hydraulic press at the Jiangnan Shipyard, kicking off an unprecedented industrial battle. The large components of the [-]-ton hydraulic press needed to be made of extra-large forgings and cast steel.But at that time, our country did not have such large steel, so we could only use splicing to weld many castings and steel plates.

In May 1962, my country's first 5-ton hydraulic press was successfully manufactured. However, it was only 60 years ago. Where did the [-]-ton hydraulic press come from? Thinking of this, Jiang Yan's head began to hurt. If he had not designed this The cost of such molds has also increased a lot.

Thinking of this, Jiang Yan was a little unwilling to give up and said to Wang Honghai: "Director, just think of a way. It doesn't take us long, just process a few molds. Let me tell you, director, our project is absolutely perfect." good."

Hearing Jiang Yan's words, Wang Honghai thought for a while and said to Jiang Yan: "In this way, after the meeting in the afternoon I will find a way. If it doesn't work, I will ask the old leader to see if he has a quick way for me. If it doesn't work, you can Let’s change your design plan and see if we can use a 1000-ton section machine.”

"If you use this level, let's see how much the cost can increase."

After hearing what the director said, Jiang Yan could only agree. If it didn't work, it seemed that he would have to redesign a new plan.
