The ups and downs of life in the Siheyuan

Since he is the only technician in the factory, Li Yuan must be shouldering the responsibility when encountering technical difficulties.

Therefore, in order to establish prestige in front of newcomers and leave a deep impression in the minds of leaders.

He started working hard yesterday.

He was mentally prepared. If he couldn't handle it in one day, he would stay up all night every day.

At 8:30 in the morning, Li Yuan, who had only slept for less than 3 hours, came to the mold workshop again.

"Xiao Li, your carpentry skills are excellent. In the future, we will not need to rely on external forces for complex mold manufacturing."

When Luo Bing saw Li Yuan, he wanted to find something for Li Yuan to do.

Li Yuan just smiled and said nothing.

If you don't want to do it, it doesn't matter. It seems that he, Li Yuan, was deceived.

But in the long run, it’s not certain who will be cheated.

Now Li Yuan is doing it by himself. He can lead his apprentices, who will do the work in the future.

All these years later, the mold shop lives up to its name.

Luo Bing's mold making ability will be weakened and he will gradually move away from mold making. In the future, there will be no place for him in the mold workshop.

In order to make good molds, the mold shop needs to understand the casting process.

At first, we just put forward the precautions for using molds. In the future, the key process flow of casting will also be taken over by the mold workshop.

Now it looks like they have done too much, and in the future, they will not have the chance to do it.

Seeing Li Yuan who didn't dare to talk back, Luo Bing was secretly happy.

After all, he is just a child. From now on, he can leave these hard and tiring tasks to him.

Soon, Luo Bing left the mold workshop with his apprentice.

Li Yuan sat there and slowly let his mind wander.

Think about nothing until you feel your best mentally.

He just began to recall yesterday's various plans, and then slowly found out the advantages of each.

And find factors that promote each other, and focus on thinking about and solving awkward areas.

Finally, a brand new plan slowly took shape in my mind.

The final principle is very simple, similar to the ancient Chinese "circle cutting technique".

As the sides of a regular polygon continue to increase, it will get infinitely close to the sides of a circle.

Zu Chongzhi 1800 years ago, when calculating pi, cut 3072 squares.

It is a pity that the results have been attributed to Westerners by modern historians.

Li Yuan picked up a piece of wood and started cutting it, using a plane to cut the wood into perfect rectangular strips.

He used a carving knife to draw the curves on the drawing on both ends of the wooden strips.

Then divide the curved surface into 20 equal parts, and use an ink fountain to draw 20 straight lines on the wooden strips.

He fastened the strips of wood to a vise and made scale marks on the drill bit.

Start drilling along the straight line drawn from the ink fountain, keeping the distance between holes about 1 cm.

The holes on each straight line are of different depths, with the holes on the straight line near the center of the wood being the shallowest and the holes near the edges being the deepest.

The entire process can be explored with the mind.

After an hour, all the holes were completed.

Pick up the carving knife and start scraping slowly until all the excess wood is scraped off.

A perfect wrench mold appears in hand.

Next, with the help of a steel ruler, refinement begins.

After each small surface is repaired, hold the edge of the steel ruler close to the small surface and observe whether there are gaps or bulges.

If so, correct it carefully.

It took more than 2 hours to mold the entire handle.

Measured multiple times, no flaws whatsoever.

Next is the faucet, which is relatively simple.

This version of the universal wrench has a fixed faucet. Currently, it is only designed to have a faucet on one end. A series of universal wrenches will be launched in the future.

The current faucet is similar to a V-shaped opening, with a flat mouth on one side and inward teeth on the other.

For different types of 6-angle nuts, one side is parallel to the flat mouth, and the teeth on the other side bite one corner of the nut.

Because the teeth face inward, the bite is very strong.

The advantage is that as long as the density of the teeth is appropriately increased, it can adapt to most nuts.

The disadvantage is that if too much force is used when tightening, it is easy to leave tooth marks on the nut.

In order to solve this problem, some universal wrenches with common nut specifications will be added later.

That kind of faucet is a rectangular opening with corresponding steps on both sides according to different nut models.

Each step corresponds to a specification.

If you are in a tight space, you can only use a special open-end wrench.

It's the kind with a round head on one end and an opening on the other.

One wrench for every model.

Of course, this kind of wrench with a round head at one end and an open end at the other end can also have different specifications at both ends.

Therefore, by specializing in making different types of wrenches, a machine shop can survive very well.

The key is quality and innovation.

In order to establish the brand, a logo will be stamped on the handle of each wrench.

Unfortunately, it is empty now and needs to be confirmed by the leader.

When Li Yuan completed the preliminary production of the mold, he proposed the concept of the brand to Lu Xingyu.

Everyone actually understands the concept of brand, even in the current planned economy.

Everyone also trusts the products of big manufacturers more, especially industrial products.

As for civilian products, you have no choice. You can only buy products from whichever company has the supply.

Even so, many people will wait for the supply of the brand they have in mind if they are not in urgent need.

Such as bicycles, radios, and sewing machines.

These are generally fine because they are implemented to the same standard.

When TV production lines are introduced in the future, there will be a big gap in product quality between different brands.

Lu Xingyu felt that Li Yuan's analysis was very necessary.

The next day, all the directors gathered in the conference room to discuss the external brand name.

There was intense discussion to come up with the name of the brand.

"The name of Jiaodaokou No. Machinery Factory is too long, has no characteristics, and is difficult to remember," said Cheng Wanbiao, director of the sales department.

"It's a bit unsophisticated, how about using 'number one'?" said Hu Qiang, director of the security department.

"What's wrong? More rustic," said Wang Hongxia, director of the finance department.

Hu Qiang frowned, folded his arms and leaned on the back of the chair.

“Think about it, most of the current product brands have two characters, such as Feiren brand sewing machines, Phoenix brand bicycles, I-brand air guns, etc.

Therefore, we also consider it in two words."

Lu Xingyu set the tone, and then everyone started discussing around these two words.

"I think it would be enough to just print the Chinese characters '中华' on the handle," said Luo Bing, director of the foundry workshop.

"It's a bit difficult. The name is too big and the higher-ups may not approve it," said Ren Jia, director of the General Office, with a smile.

"Then use Huamei. I think it fits very well," Wang Hongxia said.

"Hello Huaqiang!" Hu Qiang said.

"I think, let's just call him Hu Qiang," he joked.

The conference room immediately burst into laughter.

Hu Qiang just smiled and did not say anything to refute.

When everyone calmed down, Lu Xingyu looked at Li Yuan who was silent.

"Director Li, tell me your suggestions."

"Seniors, since our product targets foreigners, what kind of brand name do you think they will recognize?"

"Yes, our goal is to make money from foreigners, and we should consider the preferences of foreigners," Cheng Wanbiao said with a thoughtful expression.

"Haha, why do you want to please foreigners? This is a matter of stance." Luo Bing's expression became serious.
