Chapter 64

I don't know if I was really annoyed by the second workshop of the general assembly, or if I was stifled by the disharmony of my family life. Lin Guanghua's plan these days is that it's a big problem that can be solved by using an electric drill. He wants to use a laser drilling machine.

Let's talk about the scheme on the manuscript. The simple principle of thermal expansion and cold contraction is that the cooling medium of this product is liquid nitrogen at minus 196 ℃. The purpose is just to cool and shrink the tension bar clamp. As for the blank of labyrinth top cover, it needs to be heated to 180-200 ℃, and then the two parts of one cold and one hot should be tightly combined.

Let's not say that liquid nitrogen cooling and rough hemp processing are not troublesome, let's say that the cost is absolutely astronomical, not to mention the wild research groups with only a few hundred yuan of scientific research funds, even led by Yonghong factory can't afford such a consumption.

In addition, if you use the processing method, the safety can not be guaranteed. In case of an accident, it is either death or injury, and the risk is too high.

"What? Can't you? "

Lin Guanghua looks at Zhuang Jianye with a nervous face, showing his rare nervousness. These days he soaks in Zhuang Jianye's dormitory and gets along with him day and night. He just knows that Zhuang Jianye is really like Shi Jun's saying. He is a little salted fish on weekdays, but he has a lot of goods in his stomach.

Let's take their project as an example. At the beginning, the three of them had a clear division of labor and did their own work. However, they found that in the general direction, he and Lu Ming were confused, but Zhuang Jianye had the clearest idea. That's not to say. Whenever he and Lu Ming had problems that could not be solved, as long as they gave them to Zhuang Jianye, he could give you two or three words.

As time goes by, he and Lu Ming simply take down the task of Zhuang Jianye, and let him just take the general direction, so as not to screw up the project.

It would be unthinkable if we put it in the past, because both he and Lu Ming are very proud people. They can never be inferior to others. But when they meet Zhuang Jianye, they can only recognize him. They can't compare their ink with others.

Lin Guanghua doesn't know if Lu Ming's idea is true. Anyway, he did it himself. For example, in the past two days, he learned a lot from Zhuang Jianye for his lack of craftsmanship. It's not too much to say that he has benefited a lot.

Because of this, when he saw Zhuang Jianye's familiar expression of constipation, Lin Guanghua's tangled heart was lost, but also vaguely excited, and he could learn something again.

"Old problems, Lao Lin, liquid nitrogen, blank heating, let's not talk about the cost of these two kinds, do you consider the protective facilities?" Zhuang Jianye rubbed his eyebrows and had no choice.

"Oh ~ ~ I ignored that." Lin Guanghua wrote it down in his little book.

Zhuang Jianye almost fell out of bed: "I said Lao Lin, can we stop joking? Your plan doesn't work. It's too high-end. Our factory can't play at all. "

"What do you say?" Lin Guanghua was not angry either. He put down his pen and looked at Zhuang Jianye.

"Use a material whose expansion coefficient is greater than the blank of labyrinth top cover, and then let the diameter size of the expanding core clamp ensure that the assembly is a little tight at room temperature, and then find a skilled fitter to knock in a little bit with a wooden hammer."

After listening to Zhuang Jianye's words, Lin Guanghua was stunned for a long time and then exclaimed: "is it so simple?"

"How complicated do you think it is?" Zhuang Jianye asked.

Lin Guanghua frowned and thought about it, nodded and quickly wrote in his notebook. Then he suddenly stopped writing and looked up at Zhuang Jianye: "you almost fooled me. We don't have a fitter. How can we knock? So I think my plan is more reliable. "

Zhuang Jianye wanted to throw his hot water pot on his head. He finally held back, but he crumpled up the page and threw it: "can a living person still suffocate his urine? No one can look for it! "

"Who are you looking for?"

"I..."

Zhuang Jianye's words stopped for a moment. He really didn't know the fitter in the factory. If he used to go to Ning Xiaodong for help, now he cooperates with his ex girlfriend. Ning Xiaodong runs away without even saying hello, as if his ex girlfriend is the God of pestilence.

As for the Ning sisters Zhuang Jianye gave up without even thinking about it. If they could do what they were doing well, they would burn high incense. To expect them to know high-level fitters was like asking them how far the sun is from the earth.

So he really can't answer this question, which is a bit embarrassing.

Looking at Zhuang Jianye, who was just talking, his old face turned red. Lin Guanghua almost laughed. As soon as he was ready to make another joke, a deep female voice rang out at the door: "you can find me."

As soon as Lin Guanghua heard this, he jumped up from the pony like a cat with his tail stepped on. As a result, he found that his trousers were not on the table. He quickly picked up the quilt and covered his lower body in shorts. Then he looked at Lu Ming who came in with Dafang discontentedly: "I told you last time that this is a men's dormitory. You can't come in casually."

Lu Ming glanced at Lin Guanghua, whose face was like red cloth, and sneered: "what's good to hide? If you have time, go and ask the men under 30 years old in the factory. When I was a child, I didn't get caught by my sister and played eggs? So you don't have to. It's not rare. "Then he turned his head and looked at Zhuang Jianye, who had quietly put on his trousers. He explained: "Uncle Wang downstairs watched me grow up. Everyone is familiar with me, so he didn't stop me coming in, so he came up directly. The fitter you just mentioned doesn't have to worry. There is a level 6 fitter in my second uncle's workshop, which should be enough."

"I'll trouble you." Zhuang Jianye was also embarrassed. When Lu Ming came in, Lin Guanghua at least wore shorts, but he only wore a small inside. Fortunately, his pants were right at the head of the bed, so he could put them on at the first time, so he would not lose face like Lin Guanghua.

But when Lu Ming didn't see it, she took out a few pages of paper from her bag and handed them to Zhuang Jianye: "it's nothing. If it's troublesome, it has to be troublesome to you. My test records of the past two days can't pass the sintering test. Please help me to see what's wrong."

Zhuang Jianye quickly took it over to avoid further embarrassment. However, when he looked at it carefully twice, he put down the paper and asked, "sister Ming, you don't have hydrogen and water vapor when sintering. How can you decompose metal to form carbon monoxide and methane, so as to eliminate carbon in metal fiber?"

"Pa!"

Before Zhuang Jianye's voice fell, Lu Ming slapped his forehead: "I said something was wrong. I forgot the reverse ventilation. OK, you're busy. I haven't done the experiment. Let's go first."

Before he finished, he went out with his bag, as if he had never been here.
