Hand rubbing nuclear fusion live in the wilderness

Chapter 129 Forging Generator Parts

In the live broadcast room, Han Yuan casually made up a name and then ignored the barrage.

He knew that the name he said would definitely be picked up by others, but so what.

If the upper echelons don't take action, they can't even determine whether they are on Earth.

There is an interesting saying.

"Once Wuchang turns off the satellite, other countries can only use the compass to identify the direction."

"Let's not talk about finding out where Wuchang is, even the plane can't go to the sky."

As for most of the people who eat melons, they are just curious about his name. He said that, and these people will stop asking.

On the contrary, there are all kinds of barrages of Master Qiu, Brother Qiu, etc., wanting his small leaf red sandalwood and monkey wine.

The mold of the bearing parts has been made, and now it only needs to wait for the high-carbon ferrochrome alloy in the crucible to melt into molten iron.

It is worth mentioning that he spent a lot of effort to get out the mold of the ball in the bearing.

Compared with the mold of the inner ring of the outer ring of the bearing, the mold of the ball is more difficult.

But if you don't make a mold and use a lathe directly, you may waste countless chromium-iron alloy turning tools to make one, which is not necessarily standard.

Therefore, South Korean won still chose to make the mold and pour the balls out and then polish them.

First use a lathe to turn out the wooden beads according to the set diameter.

Then use wooden beads to make a semi-circular mold, and then spread a thin layer of paper and sprinkle some plant ash as an interlayer.

Cover the paper with mold soil, insert a bamboo stick, and leave a small conical hole for pouring molten iron.

After waiting for the mold to dry, disassemble the upper and lower layers and take out the wooden beads inside.

After wasting more than ten sheets of paper, he managed to make some ball molds.

After about half an hour, Han Yuan lifted the lid of the refractory furnace, and from a distance, used slender iron tongs to clamp out the crucible inside.

The raw materials inside have been melted into molten iron, and the vegetable oil can indeed reach a high temperature of more than [-] degrees after being fully burned.

Just don't know what the upper limit is.

It is a pity that this method is only suitable for small-scale melting of ferrochrome for the time being, because he does not have a large amount of vegetable oil.

To extract chromium from chromite ore, he still has to solve the problem of fuel.

But now get out the generator first and then consider this matter, as long as it is enough for the time being.

Holding the crucible, Han Yuan quickly poured the molten chrome into the mold to become balls and inner and outer rings of bearings.

In order to ensure the success rate, crucibles of molten chromium iron have been turned into bearing round plants.

In the mold, the parts of the bearing cooled down, and the won was disassembled one by one and stacked together.

Under the lens, the inverted round bearing plant shines silver-white in the sun.

But each ball has a small conical tail and a protruding concentric ring attached to it.

These are caused by the lack of precision of the mold.

Han Yuan picked up a ball, snapped off the little tail, and studied it carefully, showing a satisfied smile, saying:
"It's pretty good. Although it's still a bit rough, it at least meets my expectations."

Seeing the ball and hearing what Han Yuan said, the audience in the live broadcast room were surprised.

【Anchor, you don't plan to use this as a ball in the bearing, do you? 】

[I will not discuss whether it is a standard circle, but the protruding circular seam and tail mark can't be used as bearing balls at first glance, okay? 】

[Do you want to polish it?No hurries. 】

[Although it looks quite round, the accuracy of the roller is extremely high. Can't the inverted one be used? 】

[The hardness of the balls made of chrome alloy is indeed sufficient. Now let's see how the anchor smoothes and polishes these balls. 】

[Car tool car?The two-axis lathe is barely enough to process the ball, but the hardness of the turning tool may not be enough. 】

Han Yuan picked up all the balls, thirty in total, looked at the barrage, and said with a smile: "Of course there is a way to polish it, but it's not a turning tool."

"The precision requirements of the bearing balls are very high, and the balls in the same bearing are required to be the same size."

"Although the two-axis lathe can control the feeding of the lathe-made balls, the accuracy cannot be guaranteed."

"As for how to grind it, you need to use the ball grinder I specially made a few days ago."

With that said, he took these balls, crossed the river, and came to the machine tool workshop.

In addition to a two-axis lathe, there is also a small circular grinding machine.

Han Yuan patted the instrument, put all the balls brought over into the round container on the machine, and said:

"After finishing the drawing of the generator a few days ago, didn't I draw and manufacture some drawings later?"

"This is the nineteenth-century ball grinding machine 'Ball Mill'"

After finishing speaking, he opened the lid of the grinder to let the audience in the live broadcast room pay attention to observe the structure inside the cylinder.

"Look, there is a millstone at the bottom of the cylinder and at the top of the cover."

"This is my secret weapon, haven't you been asking me what I do for the kiln?"

"It is these millstones that are burned."

"The raw materials are natural fine sandstone and clay, which are processed by mixing and then fired into ceramic grinding wheels."

"The abrasive grain of this vitrified grinding wheel is quite fine and has strong hardness."

"The frosting on the surface will break automatically after being blunted, exposing new sharp abrasive grains, and constantly refurbishing the grinding materials."

Even after seeing the grinding wheel in the ball mill, most of the audience in the live broadcast room did not believe that such a simple thing could grind balls.

【Using this crap to grind it can achieve the precision required by the bearing ball?I do not believe. 】

[This thing looks like the kind of machine that uses eggs and corn stalks to make pig feed that is often seen on Douyin. 】

[Another small sunflower class that I couldn't understand. 】

[I didn't understand it either, I only know that the anchor said that this thing can grind balls. 】

[What is the principle?Can someone with a big bird explain it? 】

[To put it bluntly, it is a whetstone, but the anchor used it to grind the balls. 】

[I have another question, even if this whetstone can polish smooth balls, how do you control the accuracy of each ball? 】

Seeing the question, Han Yuan smiled, first closed the flip cover, then connected the transmission shaft, and started the ball mill.

While the ball mill was working, Han Yuan explained: "In addition to the grinding stone, my flip cover also has a thick layer of pig iron on it."

"As the underlying abrasive turns, the weight of the pig iron gives the ball a downward force."

"The force will not be too large, but it will not be too small, just enough to keep the ball under a certain pressure and roll around on the grindstone."

"Since everyone doesn't believe it now, let's use the facts to speak."

About two or three hours later, Han Yuan disconnected the transmission shaft, stopped the ball mill, and then opened the flip cover to take out the round balls that had been ground inside.

Under the camera, the ball lying in the hand of Han Yuan has disappeared the concentric rings and tail hole marks that protruded before.

The silver-white ball is lying in the hand. Although it needs to be processed again, the smoothness looks quite good.
The most surprising thing in the live broadcast room was that after being polished by a ball mill, the size of each ball in Han Yuan's hand seemed to be about the same size.
