This is the test.

Anything is false.

Only genuine products are genuine.

Especially under the noses of so many people, the slightest flaw can be found.

Especially for large diesel engines, the crankshaft is the most core component, as long as there is a slight deviation in quality, it is easy to be checked.

Once the quality of the crankshaft is not up to par, it means that the entire internal combustion engine can be scrapped.

Forced use may lead to the destruction of the aircraft and the death of people.

This is something that no one can afford.

"Simple. ”

"Wait a minute. ”

Wang Buan smiled casually.

What's the difficulty with five-axis linkage? I have a ten-axis linkage. It can be used to make Tang Sancai.

How much strength is needed?

100 million tons of hydraulic press, repeatedly forged, enough to meet your needs.

"Let's get to work. ”

Wang Buan quietly gave an order.

The No. 1 robot sprite immediately made a production deployment.

The No. 8 machine first produced hundreds of catties of cemented carbide, and then hoisted it to the No. 5 workbench of the 100-million-ton hydraulic press.

Ten-axis linkage.

100 million tons of extrusion

The crankshaft is easily formed.

There is no need for repeated forging at all. The strength of the extrusion alone is enough.

The crankshaft that really needs to be forged repeatedly is at least used by 10,000-ton giant ships. Its total power will certainly not be less than 20,000 horsepower.

"Alright. Wang Buan said.

"So fast?" Liang Penghai was stunned.

Wang Buan smiled silently.

What's this? It's that you're asking too low.

All you ask for is the crankshaft of the internal combustion engine, not the thruster spindle of the Hangma, and not the nuclear reactor......

Seriously, this spindle is strong enough for an internal combustion engine to last for eight hundred years.

Or even eight thousand years. Unless it is destroyed by an external force.

Of course, there is no need to say these words. so as not to scare Liang Penghai.

"You thing...... How many tons?" Liang Penghai became interested in hydraulic presses.

"Thirty thousand tons. Wang Buan said lightly.

"So big?"

"What do you say?"

Liang Penghai nodded heavily.

No wonder Wang Bu'an behaved so calmly. Dare to have a 30,000-ton hydraulic press!

Also, using a 30,000-ton hydraulic press to squeeze an internal combustion engine crankshaft is absolutely enough. I feel that a 30,000-ton hydraulic press, once started, the cost can be used to make 100 crankshafts. Strangely, it seems that there are no wires in sight......

It stands to reason that with such a powerful hydraulic press, the surrounding cables should at least be densely packed.

Huaxia Erzhong's 80,000-ton die forging hydraulic press is the largest hydraulic press in the world. He went to visit and find out. That's a real Big Mac! Once you start it, the cost is huge.

Except for those parts that are very large in size, ordinary small parts are really useless. The gains outweigh the losses.

Die forging press is mainly used to manufacture high-strength titanium/aluminum alloy forgings in aviation, aerospace, nuclear power, petrochemical and other fields. For example, the titanium/aluminum alloy fuselage frame, landing gear, and engine turbine disc of the American F15, F16, F22, and F35 fighters, the titanium alloy landing plane parts of the American Boeing 747-787 passenger aircraft, the titanium alloy structural parts of the Russian Su-27, Su-33, and T-50 fighters, the titanium alloy structural parts of the European Airbus A320-380 passenger aircraft, and the 1.2-meter diameter turbine turbine of the Ukrainian GT25000 ship, all need to be forged by giant presses.

Among them, the main landing gear transmission beam of the American Boeing 747 passenger aircraft is made of TI-6Al-4V titanium alloy, with forgings 6.20 meters long, 0.95 meters wide, a projection area of 4.06 square meters, and a weight of 1,545 kilograms. The rear fuselage engine compartment of the American F-22 fighter is made of Ti-6Al-4V integral bulkhead closed die forgings, which are 3.8 meters long, 1.7 meters wide, with a projection area of 5.16 square meters and a weight of 1,590 kilograms, which are manufactured by Weiman Golden Company using a 45,000-ton die forging press. The F-22 fighter jet has a projection area of 5.67 square meters, which is the world's largest titanium alloy integral bulkhead forging for aviation so far.

No matter how you look at it, you feel that the 30,000 hydraulic press in front of you is very mysterious.

At present, the only countries in the world with more than 40,000 tons of die forging presses are China, the United States, Russia and France. There is no longer a fifth.

In other words, a hydraulic press of 30,000 tons can almost rank among the top ten in the world.

Where did Wang Buan get it from?

"Shall we continue?"

"Go ahead. ”

The crankshaft is done, and it's the camshaft's turn.

Camshafts are an important component in piston engines. Its function is to control the opening and closing action of the valves.

Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (in a two-stroke engine the camshaft rotates at the same speed as the crankshaft), it usually still rotates at a high speed and needs to withstand a lot of torque, so the design requires a high degree of strength and support for the camshaft, and its material is generally high-quality alloy steel or alloy steel.

Since the law of valve motion is related to the power and operation characteristics of an engine, camshaft design plays a very important role in the engine design process.

The camshaft is also irregular, and the machining also requires the use of high-end CNC five-axis linkage machine tools.

At the same time, find a way to ensure its strength and flexibility.

The No. 8 machine produces high-temperature corrosion-resistant alloys.

Hoisting to 100 million tons of hydraulic presses.

Ten-axis linkage extrusion.

The camshaft is formed in one step.

Its surface is so smooth that even the sanding step can be omitted.

"So fast?" Liang Penghai felt incredulous.

"Normal speed. Wang Buan said lightly.

Soon?

It doesn't feel fast at all.

In fact, the 100 million ton hydraulic press has 16 workbenches, of which 15 can be linked with 10 axes.

In other words, fifteen camshafts can be squeezed at the same time. It's a pity that Liang Penghai doesn't need so many camshafts. Otherwise, within a few minutes, you can give him a whole bunch.

Next is the flywheel and impeller.

These are all widgets. However, the processing is also not easy.

Because their thickness is limited. Some must also be thin. This requires the strength and toughness of the raw materials to be very good.

In addition, the temperature is extremely high when it is running at high speeds. It must be resistant to high temperatures and corrosion.

Of course, these are trivial things for high-temperature corrosion-resistant alloys.

1800 tons of heavy pressure, 180 tons of centrifugal force, 1800 degrees of high temperature, more than enough.

The eight tables of the 100 million ton hydraulic press are extruded together, with four impellers and four flywheels, forming at one time. It took less than thirty seconds.

"So fast, can the quality be up to standard?" Liang Penghai couldn't help but doubt.

"I don't know. Wang Buan said lazily.

"Huh?"

"Test yourselves. ”

"Oh. ”

Liang Penghai wanted to speak and stopped.

He felt that Wang Buan's behavior was strange. He doesn't look like a businessman at all!

People who do business are eager for customers to come to their door, and they can't wait to brag about their products. If your product can reach a score of five, it should be blown into at least an eight. If it's eight, it's definitely going to be blown out of 10, blown to 100% perfection. However, Wang Buan, it seems that it doesn't matter at all? Do you like it or not, do you like it or not?

Could it be that this is full confidence in his own products? Or do you think that he Liang Penghai is too uninformed?

However, what Wang Bu'an said in his last sentence was not wrong.

Seeing it with your own eyes may not be true. Only machine inspection data is convincing.

"Are there any specific parameters?" asked Liang Penghai.

"Definitely meets your requirements. Wang Buan said lightly.

"Can I check it myself?"

"Yes. ”

"Good. ”

Liang Penghai beckoned.

Someone immediately took the crankshaft away and went for an industrial inspection.

Although I have witnessed the production process of the crankshaft, the real data still depends on cruel testing. Only data can convince people.

"Mr. Wang, I invite you to dinner. Liang Penghai said.

"Okay. Wang Buan did not refuse.

"What do you think of the Hilton?"

"Yes. ”

Wang Buan has no objection.

The group then headed to the Hilton Hotel.

As soon as he got out of the car, Wang Bu'an saw a familiar shadow.

Chen Binghong.

She's actually there.

She also sensed Wang Buan's existence.

"Boss Liang, I have a friend here. I don't mind adding a pair of chopsticks. Wang Buan said.

"Of course I don't mind. I can't ask for it!" Liang Penghai said with a smile.

Wang Buan then hurried to Chen Binghong's side.

Chen Binghong looked at him suspiciously.

"What are you doing here?" asked Wang Buan.

"Wait for someone!" Chen Binghong said with a frown.

"I'll invite you to dinner, do you have time?"

"Are you inviting me to dinner?" or are you inviting me to dinner with flowers?"

"Is there a difference?"

"If you asked, I would have agreed. If you borrow flowers to offer Buddha, then you are exempt. ”

"Okay. I have something to ask you. ”

"Really?"

"Really. ”

Wang Buan said very seriously.

He really has a request for Chen Binghong. The main thing is to get a company structure or something.

Now he feels empty-handed and has no helper. There is no office space. The customer came to the door, and there was not even a receptionist. Everyone can only stand in the barren grass and talk.

He doesn't need a very large, very formal company. It's just a small company.

Ability to receive customers. Ability to contact customers. Ability to respond to customer needs.

Ability to contact a logistics company for shipments. Ability to receive money.

In the biological chain of the manufacturing industry, he belongs to the upstream and needs the cooperation of downstream manufacturers.

After experiencing two weeks of hardship in Zunchi electric vehicles, Wang Buan secretly swore that he would never make terminal products.

I only sell raw materials, I only sell technology, and I only stand behind others.

Centright Metal Equipment Co., Ltd. is a good empty shell. The problem is that Gu Xialiu's actions are not so fast.

"I'm sorry. My friend is here. Chen Binghong said with a smile.

"Oh. Wang Bu'an glanced back.
