Chapter 49： assembly

"The cylinder blocks of modern engines have become diversified. In the past, there were indeed more cast iron cylinder blocks.

But up to now, with the continuous advent of new materials, forged cylinder blocks are also becoming a trend.

What I am doing now is the engine of the forging process.

Some veterans may have to ask, why choose forged cylinder? Wouldn't it be nice to use the original cast iron?

Compared to cast iron engines, this forged engine is made of alloys.

This alloy is a whole metal, and its metal molecules are arranged very tightly.

The tighter the metal molecules are placed, the higher the fatigue resistance and the stronger the impact resistance.

These alloys usually have the characteristics of light weight and good heat dissipation.

Then there is the forging process, which is to cut a piece of alloy from a metal block of suitable size with a machine tool bit by bit.

The casting process, to put it bluntly, is to make a mold, pour molten iron into it, and wait until the molten iron solidifies, and you will get a cast iron engine.

Does this sound very low, does the forging process sound very high-end?

Also, the forging process is much more expensive than casting, so this is a disadvantage. "

In front of the camera, Li Zhenhua introduced the advantages of forged engines bit by bit.

And the number of people in the live broadcast room has not been lost, and it has stabilized at the number of these thirty or so people.

'Dididi...'

The processing center issued a prompt sound, heard the sound, and left the camera lens of the second camera,

Before returning to the machining center, open the protective cover and remove the cut cylinder from the fixture inside.

Holding the cylinder with residual temperature in his hand, he came to the resting table in front of the second camera.

Then he put the piece of metal back in place again, and the machining center was up and running again.

The live broadcast has been going on, and the time of the day is slowly passing by in the live broadcast.

He also gradually got used to the days of working while chatting with water friends in the live broadcast room.

As the sky gradually darkened, he put away the last cylinder produced today and came back to the camera.

"Everyone in the live broadcast room, I will be here first today,

My live broadcast room will not be closed, it will be open at night,

Of course, no one is here, only the machine tool is with you,

Then I'll go home first, see you tomorrow. "

After speaking, he walked towards the door of the workshop, and his figure gradually disappeared in front of the camera.

After that, his life became regular, every day was two o'clock and one line, workshop and blacksmith shop.

And the cylinders of the engine were also made by him. These cylinders he designed,

There are two specifications, which are applied to the two displacement engines he designed.

Three sets of each type were manufactured, and he planned to make two prototypes of each displacement, and the extra ones would be equivalent to spare parts.

Cylinders, master cylinder blocks, pistons, main connecting rods, crankshafts, central rings, etc. were all pulled out by him one by one.

As for the water friends in front of the live broadcast room, as the number of engine parts increased, they gradually became incomprehensible.

Many people are asking what is this made of, the more it looks the less it looks like an engine,

But Li Zhenhua did not answer this question, but just let them wait and see.

During this period of time, many people have poured into the live broadcast room, and his gimmick of never closing the broadcast has played a big role.

Some curious people also often come to the live broadcast room,

When he was there during the day, the number of people in the live broadcast room remained at one or two hundred people, and the number was also slowly increasing.

Everything is proceeding in an orderly manner, and the patent materials submitted to the law firm in advance have been submitted to the State Patent Office.

Those who can apply for inventions can apply for inventions, and those who cannot apply for inventions can apply for utility models.

All patents, large and small, have entered the publication period, and some have already entered the substantive examination stage.

Liu Xiaodong's work here is also going smoothly. After all, he has been in the county for such a long time.

It is very easy to register the company with the Industrial and Commercial Bureau. The business scope of the company is very wide.

Anyway, he has included everything about motorcycle manufacturing. Of course, it can't be all of them. Anyway, the important ones are all within the scope of business.

The issue of Guo Shugui's application for qualifications has also taken shape, and everything is developing in a favorable direction.

It has been more than ten days since Li Zhenhua started working on this day.

On this day, he finally manufactured all the parts of the engine,

On this day, Liu Xiaodong and Guo Shugui also made a special trip to see Li Zhenhua assemble the engine.

An open space in the workshop has long been filled with parts.

The live broadcast room was also extremely lively, with more than a thousand people already watching.

[Fuck, a newcomer has appeared? 】

[Look at the fat man next to the anchor, he looks so funny, doesn't he look like the one who raises elephants and talks about cross talk. 】

[Upstairs, you can just report Sun Yue's ID card directly! 】

[It's a big battle today, what are you planning to do? Those who are too big can say no! 】

All kinds of messages have been swiped on the public screen, and many messages have been swiped past because they can't be read.

Li Zhenhua's mind was not in the live broadcast room either, his attention was all on the parts around him at the moment.

"Can we start now? I'll watch what's going on in the live broadcast room, and take a close-up shot with the camera."

This is the job Guo Shugui found for himself, and he returned to his old job again.

"I'll help you. You tell me how to do it. I'll help you with whatever tools you use."

Liu Xiaodong has also found his own position, which is similar to the way he swung the sledgehammer before.

"start."

As his words fell, UU Reading also started to move his hands.

First take out the main cylinder with five holes around it and put it in the middle, and then assemble the parts inside the main cylinder.

Pistons are inserted into the master cylinder, followed by connecting rods, crankshaft, and finally all connected to the center ring.

Soon the engine was slowly taking shape in his hands, touching butter where it should be touched, and adding lubricating oil where it should be lubricated.

The engine formed a large bulge on the front, and there were five large holes around the circle, and the piston leaked out of the holes.

At this point, the engine is basically assembled.

Only the last five cylinders around were left to be assembled, and Li Zhenhua stopped at this moment.

Came to the side and took a sip of water, the live broadcast room was about to explode.

"Come here, a lot of people are asking questions in the live broadcast room, and I don't know how to answer them.

Come over and take a look, I'll take some close-ups with the lens. "

After taking a few sips of water, he took the cup to the computer, and first glanced at the number of people in the live broadcast room.

But this is amazing, the number of viewers actually shows that it has reached 30,000, and it is still rising.

Looking at the number of people, it was only then that he realized that he seemed to be on fire?

How come so many people are watching? Isn't it just assembling an engine, what happened, what did he miss!

During the time when he was in a daze, the news in the live broadcast room had turned into exclamation of keeping the formation.

[Fuck, is this a star engine? 】

[Fuck, is this a star engine? 】

[Fuck, is this a star engine? 】
