1488 The Benefits of 1 Body Molding Are Many

Obviously someone still wanted to ask Xiao Feng how he could guarantee the production of such pipes.

Because once this shackle is lifted, then such pipes can be put on the line in large quantities and mass-produced and used.

In the past, we have also tried to use other methods to produce such pipes, such as lost wax casting, but it is difficult to control the thickness of the cast pipe.

So in the end this method was abandoned, and the traditional physical processing method was still used.

But this puts very high requirements on processing tools, and this is the main reason why it plagues the military.

We don't have that many machine tools...

This has led to the delay in the production of our aviation development.

Now Xiao Feng said that he can produce, and almost everyone present has seen some videos of his machine tool.

If it is really possible to ensure that the machine tool can drill out the iron pipe at will, then in the future, this kind of pipe that will cause everyone a headache can be produced at will?

How much can everyone want?

If that is really possible, it will not only solve the problem of the Air Force's aviation development.

Many problems faced by the navy and army equipment will also be easily solved.

For example, hydraulic pipes produced by this technology can be used in hydraulic equipment.

The army and navy are both major users of hydraulic equipment.

Especially now that the army is equipped with a large number of self-propelled artillery, as well as tanks and so on. These weapons and equipment use a large number of hydraulic equipment.

Not to mention the navy, with so many warships, more hydraulic equipment is used.

There is also this kind of integrated pipe, which is the most lacking for the navy.

If you don’t believe me, go to the warship and look at the cables inside the warship.

Many pipes are welded, or riveted together with rivets.

These pipelines may not have any problems at ordinary times, but once they encounter high sea conditions or fight at sea, it is likely to affect the survival of warships.

Because of high sea conditions and naval battles, warships will inevitably be hit and deformed.

At this time, if some internal pipes break, it will definitely affect the performance of the warship.

For example, we can often see warships being hit by enemy shells in American war movies.

It is not terrible to have a large hole on a warship. What is terrible is that the pipes in the various cabins below the deck are broken.

The rupture of the steam pipe will lead to insufficient pressure of the gas turbine, resulting in insufficient power output, seriously affecting the performance of the warship, and greatly reducing the survival probability of the warship.

Also, if the lubricating oil pipeline ruptures, it will be even worse, which may directly cause the engine to stop.

There are also submarines. When attacked, the various internal pipelines are very prone to bursting.

And the bursts of these pipelines are almost all welded or riveted links.

And the more such links there are, the higher the chances of a blowout occurring.

And if these pipes are integrally formed,

Then it is easy to avoid these problems.

Because there is no doubt that the sturdiness of the one-piece pipe is definitely much stronger than these welded and riveted pipes, even more than twice as strong.

Therefore, it is naturally possible to withstand greater pressure, and it can also withstand greater deformation.

The most important thing is maintenance, and it is easier.

And if a large number of such integrated pipes are used on warships, there is another advantage.

That is, the dead weight of the warship can be greatly reduced.

In the past, when steel-hulled warships were born, a large number of rivets were used on warships, and large steel plates were spliced ​​together to form a complete warship.

This kind of warship weighs thousands of tons or tens of thousands of tons, but it can't actually hold too many soldiers and artillery shells, nor can it hold too much coal.

Because he weighs too much, if he loads too many soldiers, he will have to load more living supplies, which means he will consume more fuel.

Such a boat becomes a short-legged boat and cannot run very far.

Because he can't go far, he needs to supplement coal burning.

And those rivets accounted for a large part of the warship's own weight.

For a warship of more than 10,000 tons, at least 3,000 tons are the weight of rivets. This linking device not only takes up a lot of space on the warship, but also takes up a lot of its own weight, and also increases fuel consumption.

It was not until World War II that the technology of producing warships in various countries in the world was further improved.

Welding technology began to be widely used, and rivets began to be gradually eliminated from the stage.

However, even if welding technology is more advanced than rivets, rivets cannot be completely eliminated from the stage of history.

Because when it comes to strength, rivets are still irreplaceable in many key parts of a warship.

Because the parts connected by rivets are stronger than welding.

Even now, there are still many key parts on the warships of various countries in the world, which still rely on riveting.

For example, many of the various pipes inside the cabin are riveted.

The rivets used for these riveting also account for a large part of the ship's own weight.

Now, if this kind of integrated pipe is widely used on warships, many rivets on warships can be eliminated.

Not only can it release a large part of its own weight, but it can also greatly improve fuel economy and range.

Moreover, this one-piece molding technology can be used not only on pipes.

Many special-shaped parts on the warship can also try to use this new machine tool for integrated processing.

In this way, it is of great benefit to the light weight of warships.

Because the reduced weight can be completely turned into combat effectiveness, which means that the warship can hold more fuel, have a longer range, and can carry more missiles, weapons and ammunition...

Anyway, no matter how you look at it, the integrated molding technology brought by this machine tool has great benefits!

It's no wonder that there will be so many people, and they can't wait to ask aloud at this time

But it was quickly stopped by the general who took the lead before...

Then he asked someone to take out several other workpieces and put them in front of Xiao Feng.

"What about these? Can you produce these?"

When Xiao Feng saw the artifacts in front of him, he immediately understood them all.

These are the turbofan blades on the internal rotor of the aviation engine.

The shapes of these blades are very beautiful, unlike those ordinary turbine blades we have seen.

The shape of these blades is very special. It can be said to be an S-shaped blade with a very complicated curved surface. It can be said to be the most difficult product among all workpieces.

And this kind of blade is not the ordinary thin layer of iron.

Instead, it has a cavity inside and leaves with tiny holes in many cross-sections.

Just by looking at the shape, you already know that it is very difficult to process, but when you look at those small holes, you know how difficult it is to process.

"I'm not going to hide it from you, this is the turbofan blade on the aviation engine. It is very difficult to process this kind of blade."

"Now we mainly use the lost wax casting method, because we don't have the single crystal growth technology like the Americans, so we can only use the old routine."

"It is to use special porcelain clay to make molds. After the porcelain clay molds are made, they are fired into ceramics, and then wrapped with beeswax on the outside, so as to ensure that there are cavities in the poured leaves."

"The completed pottery pottery must be put into the pottery liquid to rotate and sizing, and then put into the bellows to spray the pottery pottery clay to shape it."

"It is air-dried before precision casting..."

"And after the pouring is completed, we have to take X-rays of each turbofan blade to see if there are any trachoma and dark wounds on the blade..."

"Anyway, the whole production process is very cumbersome, there are many processes, and the progress is very slow."

"The most important thing is the yield rate, the yield rate, we have no way to guarantee it yet."

"Sometimes, often a small mistake, a whole batch of products are scrapped."

"Sometimes, without even knowing the reason, a whole batch of products is also scrapped."

"As a result, the production speed of our turbofan blades has been unable to increase, and the cost has remained high."

"You just said that your robot is particularly good at one-piece molding technology in terms of machining."

"In this case, I want to ask you, can you see if such a blade can be processed in one piece?"

The old general obviously also came from the technical field, so when he explained the production of the turbofan blades to Xiao Feng, he explained it in great detail.

And Xiao Feng is not an industrial rookie, after all, he has been dealing with the experts from Xinghuo Factory for quite some time.

So he also has a deep understanding of this kind of machining technology.

At this time, the old general's question was very professional, and he didn't dare to draw conclusions easily.

So he turned around and started discussing with several experts who came behind him.

Among these experts, two are cloning experts. It can be said that the industrial robot of Xinghuo Technology was built under their guidance.

So the two of them are obviously more professional in terms of the robot's capabilities and various industrialization issues.

The two knew the key to producing this kind of blade just after hearing what the general said.

"Actually, the main difficulty lies in the mold production before pouring!"

"The precision requirements of this kind of mold are very high, and considering the problem of thermal expansion and cold contraction when pouring liquid metal, the requirements for error are very strict."

"Many key steps of the mold need to be made by hand."

"This is the key to improving production efficiency, but for our machine tools, these are not problems."

"We can use machine tools to process molds that meet their precision requirements, and because it is a mold, there is no need to worry about any mistakes."

"Even if some molds have errors, we can still pick out the defective products before the final process."
