At that time, in the era of poverty and whiteness, in order to engage in construction, the country tightened its belts and got on the horse, and there were many things, relying on self-reliance and hard work, and such model workers such as the iron man Wang Jinxi emerged, relying on their kind of spirit, so that the motherland changed from an agricultural country to an industrial country.

And now, Qin Zhenhua has put forward this slogan again, it is not difficult for a machine factory to engage in automobiles, but it is difficult to engage in modern automobiles, using hammers to beat and beat to make automobiles, and using advanced stamping machines to stamping on the mold piece by piece, and the production efficiency of the two is not the same.

Seeing the modern factory, Qin Zhenhua put forward this requirement, which is also very strict, and among them, for the car, the girder is the most critical.

The girder is the main stressed part of the car, from the front to the rear of the car, made of high-strength steel, rolling this steel, it requires a large forging press.

The Yellow River plant does not have this kind of equipment, it can only be pressed in sections, after pressing out, riveted with rivets, the strength is naturally not good, and the second automobile, the use of the direct forging of the entire beam, the use of the 10,000-ton forging press, the machine is strong, the quality of the press is also quite good.

A machine factory is to build tanks, tanks do not use girders, tanks are welded with steel plates, the forging of steel plates, that is done in the steel mill, although a machine factory has forging presses, only small hundreds of tons, the largest one is a thousand tons, 10,000 tons of forging presses, there is no.

No, what are you afraid of, there is nothing you can make yourself!

"Make it yourself?" Hearing Qin Zhenhua's words, Mia kept shaking her head: "Impossible, you don't have this ability at all, the 10,000-ton forging press requires a very strong pressure to ensure the precision of plunger processing, which requires special cutting equipment to do, you don't have this kind of equipment at all, you can't make it." ”

"And what if we make it?" Qin Zhenhua asked rhetorically.

Mia turned her head and looked at Qin Zhenhua with a serious gaze: "Make it?" How are you going to build it? ”

"Of course we have our own way." Qin Zhenhua said: "We are studying each process, and when it is made, it will surprise you." ”

"Impossible, impossible." Mia said, "I don't believe it. ”

After saying that, he thought about it again and said, "I want to see how you make it." ”

"Want to see us? It's a trade secret. Qin Zhenhua shook his head: "No, absolutely not." ”

"Your trade secrets? It is of no value to us, we in Germany have a perfect production plan for 10,000-ton hydraulic presses, there is no need to steal from you, I am just curious. ”

"That's not going to work, it's a secret from our factory." Qin Zhenhua glanced at her: "However, if you join in and give us advice together, then we can still consider accepting your request, but there is no salary, you are in the spirit of internationalism to join us." ”

Mia immediately understood, this Qin Zhenhua is quite calculating, this is calculating herself, let herself work for them for nothing.

Come here,Mainly responsible for the sales and maintenance of the diesel engine of the MTU company,In fact, this engine has stable performance,It doesn't require too much manpower at all,Mia is usually idle and boring,That's why she often comes to Prairie City。

Now, hearing that the other party wants to make a 10,000-ton hydraulic press by local method, Mia is interested, as an engineer, she is interested in any way to transcend her ability, what are they going to do?

She wants to know, and if she wants to know, she has to join in and work for free for the other party!

Of course, Qin Zhenhua also fell in love with Mia's technology, when he first went to MTU, he met Mia, she is the most outstanding engineer of MTU, and she is also the most outstanding engineer in Germany, and even the world! If nothing else, a skilled machine operator, this one is enough.

It depends on Mia's willingness to make a move, and it is good to tempt her with this condition.

"You want me to join?" Mia said, "Aren't you afraid that I will leak secrets? ”

"If you join, there will be a code of confidentiality, and we believe you." Qin Zhenhua said.

"Hmph, you can use me, right? However, don't bother, if you can't build it, you have to make a 10,000-ton hydraulic press, in order to be able to produce 10,000 tons of pressure, the main cylinder of the hydraulic press must be at least two meters in diameter. Mia said: "You don't have this kind of large-scale cutting equipment, and you can't build this master cylinder, if you want to get it, then you have to buy it, if even the master cylinder is purchased, let alone you make it yourself." ”

No matter what hydraulic press it is, the main component is a hydraulic cylinder, which produces 10,000 tons of pressure, the diameter of the main cylinder is very large, the piston and the outside cylinder wall, the combination must be particularly tight, it needs to be used with a large milling machine for precision machining.

That's right, if you say it, it needs to be the protagonist of the boiling Toshiba machine tool incident in later generations, such a super machine tool can do it, don't look at such a simple piston, it is not easy to process!

If you don't have this kind of equipment, then you can't do it, since you can't do it, then you have to outsource, this is a key component, this component is outsourced, and what is self-development?

At this time, Mia also felt strange, how did she talk about a specific plan? This Qin Zhenhua is clearly here to fool himself.

What if he asks for help with processing, or even contact?

"We've thought about this for a long time." Qin Zhenhua said: "We can't process such a master cylinder, we can only use an alternative. ”

The alternative?

Mia looked at Qin Zhenhua and only heard him continue: "We plan to use six sub-cylinders, so that each sub-cylinder plunger only needs to generate a pressure of 2,000 tons, and our existing processing tools can only process a maximum diameter of 0.8 meters, which is exactly the maximum diameter we can process." Moreover, in this way, when we use it, in addition to the use of 10,000-ton forging presses, we can achieve the pressure value by adjusting the number of working cylinders, because of the limitation of pairwise use, so we can get 4,000 tons, 8,000 tons and 12,000 tons of pressure, and its adaptability is stronger. ”

Qin Zhenhua proudly said his plan, just like a dump truck, some dump trucks use a thick hydraulic column in front, some don't, and use four hydraulic columns under the carriage, the strength of each is not very large, but four together, it is enough.

"In this way, it can be solved, but it is not easy to control the synchronous operation of these hydraulic columns." Mia said: "If it is not synchronized, then what is suppressed is waste." ”
