PS: The fifth shift is over, asking for a monthly pass.

Bangs took out drawings and built the engine.

However, when it came to molds, Liu Hai decided to make them himself, let Li Dali prepare the materials, and then start casting them himself.

This time, Bangs made a new material, boron-containing cast iron, that is, it contains 0.07% boron to increase wear resistance.

There are many types of wear-resistant cast iron, high calcium, rare earths and so on, but at this stage, boron is better.

With this, the life of the cylinder liner is greatly increased, which is why the bangs have to cast their own parts, so that they can make new materials, anyway, they are manufactured, and they have to be tested, and when the test finds that the life is so long, then check backwards, and slowly find out.

The material is like this, even if it is added 0.01%, it will have different properties, and the later liquor industry learned this trick, one ton plus one drop of thirty-year-old liquor, this ton is thirty-year aging.

Subsequent crankshafts, piston rings, etc. will be made of new materials, of course, for this time it is a new material, not for modern times.

The main reason for using new materials is to increase the service life, and in today's road conditions, things that often break are not friendly to users.

The engine alone, excluding the gearbox, is not very complicated, but the procedures required are quite complex.

Molds for casting cylinder liners, casting crankshafts, casting pistons, and manufacturing piston rings.

Bangs are made with a four-stroke engine.

In the maintenance department, bangs make motorcycle engines in it, and it's good that no one cares.

Factory director Sun Aiguo is preparing materials, about the production technology of 100 tons of hydraulic presses, etc., because now it is impossible to produce this kind of hydraulic press in Kyoto, on the one hand, it is troublesome to transport various materials, coming and going, and the finished products manufactured secondly, as for those factories can produce, this is the plan above.

At this time, there are no technical patents in the mainland, and there are no in the entire circle of Big Brother, as long as you can copy Big Brother's things, then make them casually.

Patents are only available in the U.S.-dominated circle.

After the procurement plan of the first machine department and the big brother was handed over, the big leaders above were also very surprised, the hydraulic press was used a lot in the industrial system, and many products were needed.

Later, I saw that Big Brother was willing to provide a large number of high-pressure explosion-proof pipes, and I was very surprised.

Some key parts of large-scale equipment, sometimes broken need to be urgently ordered from the big brother, this price of course there is a say, I didn't expect this time to open the supply?

"This motorcycle factory, but the one who makes honeycomb coal?" As soon as the big leader asked, the secretary hurriedly reported the detailed process.

"Yes, leader." When the secretary heard the leader's question, he immediately nodded in affirmative.

"This factory director is amazing, he actually digs a pit for Big Brother's people." The big leader continued to look down, and saw Sun Aiguo competing in the first machine department, and then built a temporary 500-ton hydraulic press, so that the big brother not only reduced the price, but also did not limit the quantity.

"Leader, Director Sun is a good factory director, and this time he can save a lot of foreign exchange." The secretary naturally does not say bangs, the level of bangs is too low to be worth paying attention to.

After the leader read it, he took out a cigarette, the secretary hurriedly came up to light the cigarette, and the big leader said: "Since the high-pressure explosion-proof pipe can be manufactured by itself, then make a part of it yourself, and it is not good to always look at other people's faces, and since the other 500-ton hydraulic press can make samples, you can continue to do it, be bold and magnify, don't be afraid of failure, and start again if you fail." ”

"Okay, leader."

"With all the money saved, how many pigs and how much grain will be sold, the masses themselves are reluctant to eat, such a person still has to let the masses know." The big leader said again.

"Yes, leader." The secretary immediately understood, this was going to be promoted.

The big leader spoke, and the following was quickly executed, and before Liu Hai got off work, Sun Aiguo trotted over: "Xiao Liu, clean up, there is a reporter to interview." ”

"Director, isn't this appropriate?" As soon as Liu Hai heard this, he hurriedly said.

"Why is it not appropriate, you are a great hero." Sun Aiguo immediately said.

Liu Hai hurriedly said: "Factory director, do you think it's better to publicize individuals, or to publicize our workers?" ”

When Sun Aiguo heard this, he was excited, and Liu Hai continued: "Factory director, you have to publicize that our workers have strength and can overcome everything." ”

Sun Aiguo slapped his bangs on the shoulder twice: "Good boy, I am not as good as you in some aspects, and I almost did something wrong." ”

"Hehe, factory director, don't you hurry up." Liu Hai smiled, you must not be in the limelight at this time, otherwise a certain transport captain on the other side of the sea may not wait to see you in the newspaper, and give a casual .......

The director of the factory immediately went, discussed with the secretary in a low voice, overturned all the things that were originally going to be said, and then praised the workers for not being afraid of hardship, working as one, breaking through many difficulties, and completing the research and development of new machines, of course, the motorcycle factory was also famous.

Kyoto is better, people in Kyoto know that there is a motorcycle factory in the east of the city, the motorcycle is not very good, the production of honeycomb coal machines, which has made a hydraulic press, and the factory has expanded and expanded, recruited workers and recruited workers, and was also commended by the Ministry of Machinery.

Those who read newspapers in other places are a little stunned when they listen to the radio, Kyoto Motorcycle Factory, making honeycomb coal machines? Build hydraulic presses? Are you sure it's not a machine shop?

Liu Hai thought that this matter was over, and as soon as he went to work the next day, he was called into the conference room: "Xiao Liu, can you get the plan for the production of high-pressure explosion-proof hoses you said last time?" ”

"Factory director, do you want to do this?" When Liu Hai heard this, he estimated in his heart that there must be a task.

"The big leader said that if we can do it, we will do it ourselves, and let's try it first." When Sun Aiguo heard the big leader praise the motorcycle factory, his excited legs were almost weak, so he hurriedly beckoned his bangs over and asked.

"It can be done, but it takes time, and most of it is a copy of Big Brother." Bangs actually want to do it, but a person's energy is limited, the design of high-pressure explosion-proof hose is not complicated in theory, the key is the follow-up parameter debugging, temperature, feeding speed and so on.

"Then do it, who needs the full cooperation of the factory."

"Don't be in a hurry for the time being, I'll check the information first, and then the drawings will be issued." Liu Hai hurriedly waved his hand and said, many things other people came in, asked why this was designed like this, why was that designed, I want to explain it, and I was afraid that some modern words would pop up, so I just thought about it myself.

When the drawings come out, do them according to the drawings first, and then you need to change them again.

"Can we conduct a test in half a year?" Sun Aiguo said a conservative date.

"Almost, let's get the machine out first, and then change it." Liu Hai thought about it for a while, the motorcycle is three months, the high-pressure explosion-proof hose machine is almost three months, the main technical difficulty of the high-pressure explosion-proof hose is in the water mouth, that is, the high-pressure pipe changes from rubber particles to the pipe and then laminated, and the rest does not need much technology.

Liu Hai returned to the maintenance department, looked at the motorcycle engine drawings, and muttered in his heart: "I can finally build a motorcycle." “
