The Rise of Heavy Industry 1980

Wang Chaoyang was stunned: "I'm

Wang Chaoyang!" Zhang Miaomiao raised her eyebrows and said, "Of course I know that you are Wang Chaoyang!" What I want to ask is, how do you know so much knowledge of mechanical design and processing? Stress concentration, technological process, and fourth strength theory...... Even my teacher doesn't know these things, how do you know about them?"

Wang Chaoyang pinched his eyebrows.

The most worrying thing still happened, fortunately, he had already thought about the rhetoric in advance, Wang Chaoyang said

: "I grew up in the Red Star Factory since I was a child, I read and listened a lot, and I understand a lot ......of nature" Zhang Miaomiaoxing's eyes widened: "Nonsense! I don't know the situation of the Red Star Factory, who can teach you that knowledge?"

Wang Chaoyang: "Listen to me finish speaking! There are a lot of old books in the factory, piled up in the warehouse, I just go to read the books when I have nothing to do, and I slowly understand more than others." Zhang

Miaomiao also knew about the old books in the warehouse of the Red Star Factory, and he had also checked the information. It's just that those books are not classified at all, and they are piled up in a mess, some in traditional Chinese, and many of them are in Russian, and I heard that Gong Dehong, the old accountant at the beginning of the establishment of the Red Star factory, pulled them back in a horse-drawn carriage.

Zhang Miaomiao was still skeptical of Wang Chaoyang's words, but she didn't ask any more questions, but asked a second question: "Then why do you give me credit every time

?" Wang Chaoyang smiled: "Isn't this bad?"

Zhang Miaomiao: "Of course it's not good! Let's ...... The two of us have nothing to do with

each other!" Wang Chaoyang: "We have a relationship

!" Zhang Miaomiao remembered the matter that her father talked about the baby kiss half-seriously and half-jokingly, her cheeks suddenly flushed, and she bowed her head and said, "Don't talk nonsense!"

Wang Chaoyang smiled and said: "Actually, it is compensation for you...... Remember the first day you came to Red Star, I offended you.

Zhang Miaomiao remembered the scene when Wang Chaoyang grabbed his hand and shouted his wife, and her face was even hotter: "Don't mention the past, and you don't need to compensate me in the future! Remember no, if you use me as a shield in the future, I will never pay attention to you again!"

Wang Chaoyang grinned, this matter is really hard to say, so he had to change the topic and said: "Remember the gooseneck fillet?

After listening to Wang Chaoyang's explanation, the Red Star Factory Flower suddenly blamed himself: "The design that is out of the processing capacity is an unqualified design, why didn't I think of it, this is my fault! The gooseneck fillet is the key to the 12 mm shaft, if it can't be solved, the drawings of the new shaft can't be used! This matter is my responsibility!"

Wang Chaoyang said: "Now is not the time to talk about responsibility, the key is to solve the processing problem."

Zhang Miaomiao also knew that the key was to solve the processing problem, but she had no concept of the processing method of variable curvature and fillet at all, and she couldn't think of a solution.

After thinking about it, she felt that she had to go back to the city to find an expert to help.

However, the shuttle bus from the Hongxing Factory to the city only took one trip the next day, and it took three days to come and go, so it was too late at all, not to mention that the experts in the city would be able to solve the problem of processing the fillet with variable curvature? Zhang Miaomiao was completely unsure.

Zhang Miaomiao thought of several ways in a row, but then she denied herself, and saw that Wang Chaoyang had been sitting opposite without speaking, so she asked him what he thought.

"The idea is there, but it's crazy. Wang Chaoyang said.

"What do you think?" Eyeing Wang Chaoyang's gaze, Zhang Miaomiao couldn't help but be shocked.

"It is almost impossible to machine variable curvature fillets with a single-axis machine...... Uncle Degui's method of not wanting to die is not counted...... But with a set of tooling, it may be possible. Do you know what the principle of matching the key is? Take the outline of the original key as the trajectory line, let the cutter walk according to the trajectory line through the connecting rod mechanism, and finally match the identical key......

"I understand! You mean to make a standard variable curvature fillet first, and then ensure the walking trajectory of the cutter through tooling! This method is so good, Wang Chaoyang, you are so good, why didn't I think of it!".

If you want to use this method, then we must get the tooling scheme out as soon as possible, this set of tooling can be regarded as a set of small mechanisms, and the workload is not small...... That's why I say this idea is even crazier!

" "Do we have any other choice besides this?" Zhang Miaomiao didn't wait for Wang Chaoyang to answer, she had already returned to her seat, took out a pencil ruler, laid out a brand new straw paper, took a deep breath and said, "Then let's start!"

Although the design work is paper work, it is not an exaggeration to describe the current situation as a "battlefield". And for the two who have just finished a tough battle, they are going to "go to the battlefield again" so soon, which can definitely be described as impassioned.

Zhang Miaomiao is holding a pencil and a ruler in her hand, eager to try, quite like a woman holding a sword, killing the enemy in a heroic posture.

The

design of tooling is by no means simpler than the parts themselves, because in the process of designing tooling, it is necessary to consider both parts and actual processing, how to ensure accuracy, how to ensure size, and how to improve efficiency...... There are too many doorways in this.

In later generations, with the development of machining, almost every item has been derived into a science, and these knowledge is so huge that even Wang Chaoyang dare not say that he is proficient in all of them.

However, he still understands the basic way of thinking.

The tooling of variable curvature fillet is mainly divided into three parts, namely the trajectory, the connecting rod and the fixture used to fix the tool. Wang Chaoyang drew these structures in the form of concept paintings, and then needed to discuss them with Zhang Miaomiao and refine the design.

Although Zhang Miaomiao has always had opinions on Wang Chaoyang, once she enters the work state, she is still very focused. And Wang Chaoyang found that the comprehension ability of this Red Star Factory Flower is really strong, and his concept paintings, it is no exaggeration to say that even graduate students of Aviation University may not be able to understand it at the first time, but Zhang Miaomiao only listened to it once and began to write.

The pencil brush brushes the ground and leaves traces on the straw paper, and soon the outline of seven or eight parts appears, and the assembly of these parts together happens to be a complete tooling system!

Of course, the sketch of the concept can only present the idea, in order to guide the processing must be refined into a formal drawing, and the next work is these, and this is where the workload is greatest.

The whole set of tooling has a total of nine parts drawings, three assembly drawings, two people spread out, six drawings per person. Because they were in a hurry, the two of them sat facing each other at the table and drew with their heads bowed.

For a moment the room became very quiet, except for the sound of pencils brushing on the papyrus.

In a blink of an eye, an hour passed, the sky gradually darkened, Wang Chaoyang completed the first picture, and when he looked up, Zhang Miaomiao already had three drawn drawings in his hand.

"Sure enough, my hands are crippled......" Wang Chaoyang laughed at himself.

"It's so ugly!" Zhang Miaomiao looked at the picture in Wang Chaoyang's hand, revealing a disgusted gaze.

"......" Wang Chaoyang couldn't refute.

He is not proficient in using pencils and rulers at all, and it is even more common to smear and smear, no need for Zhang Miaomiao to dislike it, even Wang Chaoyang himself is not pleasing to the eye, but he has no tricks, and the problem of low eye skills will not be able to be changed in a while!"

"Give me your six drawings to draw, you go and pour me a glass of water, and then help me sharpen the pencil, and the straw paper is on the top layer of the bookshelf, you can also help me take some down." Zhang Miaomiao commanded.

"Okay. Wang Chaoyang said with a dark face.

My buddy is also a senior engineer, and now he is speechless enough to give a little girl a hand.
