I don't know if I was really angry with the second workshop of the final assembly, or if I was suffocated by the disharmony of family life, Lin Guanghua has made a plan in the past few days, which is called a tall and tall problem, and it is obvious that it can be solved with an electric drill, and this product is eager to go to the laser punching machine.

Let's talk about this set of schemes on the manuscript paper, the simple principle of thermal expansion and cold contraction, the result of this cooling medium is minus 196 degrees Celsius liquid nitrogen, the purpose is just to cool and shrink the tension mandrel fixture, as for the labyrinth top cover blank, it needs to be heated to 180 to 200 degrees Celsius, and then the two parts of one cold and one hot should be tightly combined.

Let's not say that liquid nitrogen cooling and blank processing are not troublesome, let's just say that this cost is absolutely astronomical, not to mention that they only have a few hundred yuan of scientific research funds, even if Yonghong Factory takes the lead, they can't afford to spend so much.

In addition, if you use the method to process it, the safety cannot be guaranteed, and if something happens, it will be either death or injury, and the risk is too high.

"Why?

Lin Guanghua looked at Zhuang Jianye with a twitching face, revealing a rare nervousness, these days he soaked in Zhuang Jianye's dormitory, and got along with him day and night to know that Zhuang Jianye was really as Shi Jun said, he was a little salted fish on weekdays, but the goods in his stomach were frighteningly rich.

Let's take their topic as an example, at the beginning, the three of them had a clear division of labor and did their own work, but they found that he and Lu Ming were confused in the general direction, but Zhuang Jianye had the clearest thinking, which was not counted, whenever he and Lu Ming had a problem that could not be solved, as long as they were given to Zhuang Jianye, he could make you feel free in two or three sentences.

So over time, he and Lu Ming simply snatched the task that Zhuang Jianye did, and let him just take care of the general direction, so as not to mess up the subject due to small losses.

If this was placed in the past, it would definitely be unimaginable, because both he and Lu Ming are proud people, and it is impossible to be subservient, but when they meet Zhuang Jianye, they can only admit it, and there is no way that the ink in their stomachs is not as good as others.

If you can't compare it, just study it seriously, whether Lu Ming has this mind Lin Guanghua doesn't know, anyway, that's what he did, for example, in the past two days, he who lacks craftsmanship has learned a lot from Zhuang Jianye, and it is not an exaggeration to describe it as a great benefit.

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

"Old problem, Lao Lin, liquid nitrogen and blank heating, let's not talk about the cost of these two, have you considered the protective facilities?" Zhuang Jianye rubbed his eyebrows and looked helpless.

"Oh~~ I ignored this. Lin Guanghua hurriedly wrote it down in his small notebook.

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, and our factory can't play at all." ”

"Then what do you say!" Lin Guanghua was not angry, put down the pen and looked at Zhuang Jianye.

"Use a material with an expansion coefficient greater than the blank of the top cover of the labyrinth, and then let the diameter of the tensioned mandrel clamp ensure that the assembly is slightly tighter at room temperature, and then find a fitter with good craftsmanship to knock it 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, "It's that simple?"

"Then how complicated do you think?" Zhuang Jianye asked rhetorically.

Lin Guanghua frowned and thought about it, nodded and wrote quickly in his notebook, then suddenly stopped his pen and looked up at Zhuang Jianye: "I was almost fooled by you, we don't have a fitter master, how can we knock?" ”

Zhuang Jianye couldn't wait to throw the kettle next to him on the head of this thing, but finally held back, but crumpled the page of manuscript in his hand and threw it over: "Can a living person suffocate urine to death?

"Who are you looking for?"

"I ......"

Zhuang Jianye was speechless for a while, he really didn't know the fitters in the factory, if he could have gone to Ning Xiaodong for help before, but now that he is cooperating with this ex-girlfriend, Ning Xiaodong ran away without even saying hello, as if his ex-girlfriend was a plague god, lest he avoid it.

As for the two sisters of the Ning family...... Zhuang Jianye gave up without thinking about it, these two can do what they are doing well and burn high incense, expecting them to know high-level fitters, just like asking them how far the sun is from the earth, it is incomprehensible.

So he really can't answer this question, and he can't help but be a little embarrassed.

Looking at Zhuang Jianye, who was still talking eloquently just now, his old face turned red all of a sudden, Lin Guanghua almost laughed unscrupulously, and was just about to tease two more words, when a deep female voice sounded 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, but found that his pants were not on the table, so he quickly picked up the quilt and covered his lower body in shorts, and then looked at Lu Ming who walked in generously with dissatisfaction: "Didn't I tell you last time, this is a men's dormitory, you can't come in casually." ”

Lu Ming glanced at Lin Guanghua, whose face was like a red cloth, and sneered: "What is there to hide, if you have the kung fu, you go and ask, the gentlemen under the age of thirty in the factory, who have not been tricked by my sister and me when they were young, have you ever played eggs?" So you don't have to be like this at all, it's not uncommon at all." ”

After speaking, he turned his head to look at Zhuang Jianye, who had silently put on his pants, and explained: "Uncle Wang downstairs watched me grow up, and everyone knows each other, so he didn't stop me when he came in, so he came up directly, the fitter you just said don't have to worry about it, there is a sixth-level fitter in my second uncle's workshop, which should be enough." ”

"Then I'm bothering you. Zhuang Jianye was also very embarrassed, Lin Guanghua was at least wearing shorts when Lu Ming came in, but he only wore a small nenai, but fortunately, his pants were at the head of the bed, and he could put them on as soon as possible, so as not to be embarrassed like Lin Guanghua.

But Lu Ming didn't see it, took out a few pages from his bag and handed them to Zhuang Jianye: "It's nothing, if you want to say that it's troublesome, it has to be troublesome to you, my test records in the past two days have always been unpassable in sintering, you can help me see what the problem is." ”

Zhuang Jianye hurriedly took it so as not to continue to be embarrassed, but when he looked at it carefully, he put down the paper in his hand and asked: "Sister Ming, when you sinter, you can't pass hydrogen and water vapor in reverse, how can you decompose metals to form carbon monoxide and methane, so as to eliminate the carbon in metal fibers!"

"Smack!"

Before Zhuang Jianye's words fell, Lu Ming slapped his head hard: "I'll just say what's wrong, I forgot about reverse ventilation, okay, you're busy, I still haven't done experiments over there, let's go first." ”

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