For example, hydraulic presses.

For example, a five-axis CNC linkage machine tool.

"Classmate Wang Buan, you seem to have misunderstood us?" Pang Xihua said solemnly.

"What misunderstanding?" Wang Bu'an asked knowingly.

"Are you deliberately keeping your distance?"

"Definitely. I don't want to get too involved. ”

"Why?"

"I don't want to lose too much freedom. ”

"Okay. ”

Pang Xihua was obviously a little disappointed.

There is no doubt that Wang Buan is a first-class talent. He has technology, craftsmanship, and products.

It is......

He seems to be taboo about something.

It seems to be taboo to know too much. Especially in the military industry.

In fact, it is.

Wang Buan really didn't want to get involved too deeply.

It's not a matter of believing it or not. It's not a concern for anything. Rather, it is the effect of the confidentiality code.

The more secrets he knew, the more he was affected.

A lot of military-industrial secrets, it's better not to know. Otherwise, it's easy to get into trouble.

Whose trouble?

Of course, it's the trouble of foreigners.

People in certain countries are unscrupulous in order to spy on China's military secrets. kidnapping, killing, seducing, bribes...... Abound.

Wang Buan didn't want to be their target.

For security reasons, he is now restricted from leaving the country.

If you know more secrets, and you're afraid that you have to bring bodyguards with you when you go in and out, then it's not interesting. You can't do something "bad" if you want to.

There is no doubt that Deng Jia is great.

But Wang Buan didn't want to be Deng Jiaxian.

He also wants to enjoy a free and easy life, and he also wants to be drunk and drunk.

Can't go abroad?

At least you can move freely in the country, right?

If it is for security reasons, if you want to be incognito and isolated from the rest of the world in the country, I am afraid that life will not be interesting.

Is it not high enough ideology and morality? Isn't it vulgar?

That's right, it's vulgar.

That's the mentality he has.

He was very willing to help Northern Shipbuilding Heavy Industries. But definitely not overly involved.

There was also an elderly man who had not spoken. His name is Sheng Huainan. His arrival also made Wang Buan a little uneasy.

It is mainly Sheng Huainan's research field, which is very sensitive. He came to himself, and it must have been extremely secretive.

Or, the arrival of Pang Xihua is just a deputy car. Sheng Huainan is the main master.

Moreover, Wang Buan also felt that Sheng Huainan did not have a good impression of himself.

It must be because of those propellers.

He made drastic changes to the propeller without authorization.

In Sheng Huainan's view, such changes have not been rigorously verified.

Without rigorous research, it will be rude and chaotic. It made it hard for him to believe Wang Buan.

"I have a 500,000-ton hydraulic press and a five-axis CNC machining center. Wang Buan said slowly, "I can sell it to you." You can use it to enhance the manufacturing process of marine crankshafts. I'm sure I'll be able to win the prize in Stockholm by then. ”

"Are you sure it's 500,000 tons?" Pang Xihua said unexpectedly.

"Of course. ”

"Tell me. ”

Pang Xihua said calmly.

He tried to suppress the excitement in his heart. so as not to let Wang Buan be underestimated.

North Heavy Industry has a hydraulic press of 50,000 tons.

The vast majority of marine forgings can be produced by themselves.

North Heavy Industry also has five-axis CNC machine tools.

Some precision parts can also be produced by themselves.

All kinds of ships produced by the Northern Shipbuilding Industry Co., Ltd. are all domestically produced, except for a very small number of very high-end raw materials that cannot be self-sufficient.

Now, with the emergence of Wang Bu'an and his industrial park, the problem of high-precision raw materials has also been solved.

Now there is no bottleneck in the current Northern Shipbuilding Heavy Industry.

However, this is not enough.

There is absolutely no upper limit to the working capacity of the hydraulic press.

Theoretically, the higher the better. Even if it is 10,000 tons higher, the quality of the forged embryos is different.

50,000 tons, and 500,000 tons, are two completely different concepts.

If the same material is forged by both, the volume will be different.

The working capacity of 500,000 tons will forge the embryos more densely and more finely. That is, it is stronger, more tenacious.

Whether it is an ordinary civilian ship or a warship, the higher the quality of the parts, the better.

If it weren't for that, they wouldn't have the confidence to go to Stockholm!

This is the first time they have been abroad.

In addition, it was the world's largest marine crankshaft for the first time.

"The maximum working capacity of the hydraulic press is 500,000 tons. ”

"The highest accuracy of a five-axis CNC machine is 1 micron. ”

Wang Buyan briefly introduced the relevant parameters. He felt that these two machines were very suitable for Northern Shipbuilding Heavy Industry.

The 500,000-ton hydraulic press is capable of machining oversized forgings with a maximum length of 20 meters.

This is enough for a 500,000-ton giant ship.

There is no model of ship with more than 20 meters of oversized forgings that cannot be disassembled.

If it is a part that is more than 20 meters long, it must be spliced together.

If you want to be integrally formed, there is only a 100 million ton hydraulic press.

Or even more terrifying 50 billion tons of hydraulic presses. Forming forged parts of several hundred meters at a time.

Pang Xihua is still skeptical.

After all, he didn't see the real thing.

With such a huge machine, it is definitely not possible to make a judgment based on a few parameters.

It must be an in-person trial. Personally let your own technical team to conduct a detailed exploration. Confident of nominal working ability. They are also proficient in a variety of operations. Otherwise, it's a pile of scrap metal.

Of course, Wang Buan understands this.

Practice is the only criterion for testing the truth!

"Come with me. ”

"Okay. ”

The group came to Yucheng Industrial Park.

Pang Xihua's eyes lit up.

Zhuang Lang and others were also eye-catching.

Even Sheng Huainan, who had never spoken, was moved.

This is Wang Buan's industrial park?

That's a lot of behemoths. Towering. It feels like there's no end in sight.

Looks like they're all machines!

With such a huge machine, I have the impression that only chemical factories can find it.

Could it be that those chemical materials are produced by these huge machines?

No wonder the quality is so good and the performance is so outstanding.

The manufacturing process is also the world's first-class!

"You guessed it. Wang Buan said.

"Really?" Pang Xihua muttered to himself blankly.

This Wang Bu'an actually has such a large industrial park. If not to see it with your own eyes, it's incredible.

Even, even if I saw it with my own eyes, I felt a little unbelievable.

When was it established?

How was it established?

Why is there no news at all?

As if out of nowhere?

And it feels like it fell from the sky?

"Titanium alloy is also produced here?" Sheng Huainan said slowly.

"In addition to this industrial park, I have two similar industrial parks. But the quality of the titanium alloys produced is the same. Wang Buan replied cautiously.

"Can production be increased?"

"Yes. I can build more industrial parks. ”

"We need a lot of titanium. ”

"I know. If you can give me a piece of land near the Northern Shipbuilding Industry Co., Ltd., I can build an industrial park nearby. ”

"What kind of land do you need?"

"It doesn't matter if it's barren mountains or mountains. The key is to have a large enough area. At least ten square kilometers or more. ”

"As long as it's a little bit remote, it's no problem at all. ”

"Then it's settled. ”

"Good. ”

Pang Xihua is also a cheerful person.

He immediately called his men to deal with the matter.

Ten square kilometers, that is, 15,000 acres. With more than 10,000 acres of barren mountains and mountains, of course, the problem is not big. In the north, there are such barren mountains and mountains.

He felt that 15,000 acres was still too little. At least 50,000 acres are needed.

The bigger the industrial park, the better.

The larger the industrial park, the more raw materials are produced.

The supporting raw materials are at the doorstep, which will undoubtedly greatly facilitate the northern shipbuilding industry. At the very least, it can reduce the cost of transportation.

Wang Bu'an ordered the production of a set of 500,000 tons of hydraulic presses and CNC machine tools.

Soon after, the hydraulic press manufacturing center launched standard containers one by one.

In total, thirty-nine containers.

Inside is a full set of hydraulic press parts and parts for five-axis CNC machine tools.

"What is this?" asked Pang Xihua cautiously.

"Transport mode for hydraulic presses and five-axis CNC machines. Wang Buan replied.

"Can it be assembled on site?"

"Absolutely. ”

"Assemble and see. ”

"Good!"

Wang Buan gave an order.

Assemble the hydraulic press.

Assemble a five-axis CNC linkage machine.

One by one, the robot elves immediately got busy. They turn into all sorts of machines. There are cranes, there are cranes, there are manipulators, there are sliding grooves......

The robot disassembles the container and lifts the individual parts out. Assemble quickly and sequentially.

Base, hydraulic column, hydraulic shears, pressure pump......

They move very fast, like a flowing cloud, without the slightest hindrance.

In less than ten minutes, the prototype of the hydraulic press has already come out. From its outline, it is already possible to feel the great pressure of 500,000 tons.

It is more than thirty meters high. Equivalent to the height of a ten-story building. The length and width of the base are more than 50 meters.

Over there, the model of the five-axis CNC machine tool is also gradually coming out.

"This is ......," Pang Xihua asked in amazement.

"Hydraulic presses and five-axis machining centers. Wang Buan said lightly.

"Are you sure it's 500,000 tons?"

"It's like a fake. ”

Pang Xihua still felt incredulous.

500,000 tons of hydraulic presses!

Huaxia Erzhong's 80,000-ton hydraulic press is already the largest in the world. Who would have thought that Wang Buan actually had 500,000 tons in his hands?

How can it be......

Where did he get it?

Even the US imperialism does not seem to have a hydraulic press of more than 80,000 tons.

More critically......

Produced so quickly?

Assembled so quickly?

It felt like a dream. Here it says there should be light. There's really light over there.

"You made it yourself?"

"That's right. It's produced in my industrial park. ”

"Really?"

Pang Xihua felt that his thinking was not enough.

He always felt that something was wrong.

But what's wrong?

He saw everything with his own eyes. He saw the production process. The assembly process was also seen. It seems that there is nothing missing.

Wang Buan's secret, he seems to know.

But looking back, it seems that I don't know anything.

Forget it, no matter.

Anyway, it's on the land of China, so nervous about what?

As long as Wang Buan can provide raw materials and technical support as usual, he feels that it is enough.

Others, Wang Buan, did not want to be deeply involved in the Northern Shipbuilding Heavy Industry.

Of course, he was embarrassed to investigate Wang Buan's industrial park in too much detail.

After all, trade secrets are also confidential, aren't they?

Now, Pang Xihua can only regretfully position Wang Buan as a simple businessman.

The other party is technological.

The technology of the other party is in the service of business.

Zhuang Lang looked at the towering hydraulic press, and said with a mixture of gains and losses: "However, can they produce marine crankshafts?"

Wang Bu'an replied proudly: "Of course." ”

Again, that's the same sentence.

You can doubt my Wang Buan's character.

However, you must not doubt my Wang Buan's products.

"Can you make a sample?"

"Absolutely. ”

Wang Buan began to study the drawings. Robot Elf No. 1 quietly analyzes the drawings.

The drawings brought by Pang Xihua are actually just the simplest versions.

If it is to be implemented carefully, it must be an electronic version of the drawing.

However, he did not carry electronic drawings.

Still, it doesn't matter.

Robot No. 1 will automatically analyze the supplements.

As long as there is a basic architecture, it's fine.

The marine crankshaft on the earth is completely indifferent to the Transformers.

In less than five minutes, all the drawings had been analyzed and supplemented. Immediately, the robot elf issued an order to produce.

The first thing to be produced is tertiary cemented carbide. Each cubic centimeter is capable of withstanding 7,200 tons of heavy pressure.

Once the carbide has been produced, it is first transferred to the main table.

Marine crankshafts are not monolithically molded. It's spliced together.

Its largest part, in fact, does not exceed 10 meters. Therefore, the main workbench of the 500,000-ton hydraulic press is completely sufficient.

The first thing to forge is seven thick and rounded spindles.

The marine crankshaft of the snare is composed of a total of seven spindles.

The length of each spindle is not equal. Some are more than three meters, some are more than two meters, and some are more than one meter.

The diameter of the spindle is also different. Some are as high as 180 centimeters in diameter, while others are less than 150 centimeters in diameter. There is no deviation with the naked eye. However, the laser measuring instrument can easily find the error. According to the regulations, the error cannot exceed 0.1 mm. That's 100 microns.

The heavy cemented alloy was repeatedly forged by a 500,000-ton hydraulic press.

After 500 times of forging, it is sent to the auxiliary workbench for extrusion.

Repeated squeezing.

Then it was forged again and again.

Gradually, the surface of the cemented carbide became hot.

But it is repeated forging and repeated extrusion, which releases the energy in the hard carbide.

What stress, what static force, what internal gaps, what bubble holes, after repeated forging and extrusion, all disappeared without a trace.

Eventually, the entire piece of metal becomes a single-crystal blade-like existence, which is then extruded into a circular spindle.

Sheng Huainan, who has always been prejudiced against Wang Buan, also nodded quietly.

Today's first update. Ask for a little referral vote. Thank you.
