Back to the 80s Machinery Factory

Chapter 471 Cao Gai Colludes with the Enemy!

"Okay! Let me try!"

Chen Luyang confidently took the blueprints and put them into her bag.

Zhang Guoqiang, Tan Songren, and Liu Kangwen are all experienced craftsmen who have built airplanes and tinkered with cars.

What bizarre and unusual parts haven't I seen!

They've dealt with all sorts of monstrous creatures, from ox-headed demons to horse-faced demons

For them, the broken shaft seat is just a matter of spending a little more time figuring it out.

Even without blueprints, it can be measured!

However, confidence is one thing,

When it comes to actually doing the work, we still need to invite Zhang Guoqiang and a few others over to check the condition of the broken shaft seat.

After all, the drawings are "incomplete drawings," lacking detailed dimensions, fitting requirements, and assembly standards.

For critical components like the fractured shaft seat, the key requirements are the hole position, circular runout, and fit accuracy. Without the actual part, it is impossible to draw the machining drawing, let alone machine it!
but,

Fortunately, the experienced mechanics in the machine factory rely on a combination of "blueprints + eyesight + touch".

Their job is to "create something from nothing and repair the old from the new".

Often, even without blueprints, you can restore parts to near perfection just by measuring with a ruler, feeling with your hands, and looking with your eyes.

Chen Luyang hesitated when he thought about asking Zhang Guoqiang and his team to repair the spare parts.

The repair shop was short-staffed and had a lot of work to do, so it relied entirely on Zhang Guoqiang and Zuo Zhuo to keep things running smoothly.

They're spinning like tops every day, and they're still too busy to keep up.

If we were to assign them another task—to process and restore a batch of replacement parts—I wonder what other thoughts or feelings they might have.

He frowned and sighed.

A hint of determination flashed in Chen Luyang's eyes.

In the current production of standardized parts, materials are more important than anything else.

Even if Zhang Guoqiang and the others had feelings about it.

I also need to find a way to get a few people to agree and get this job done.

If turning back doesn't work, she'll go to Wang Qingzhou's office and cry, act out, and make a scene.
We must strive to win some awards and medals for these skilled workers in the factory!

But what Chen Luyang didn't expect was...
Upon hearing that a replacement part needed to be manufactured,

Instead of showing any emotion, Zhang Guoqiang and his colleagues were all beaming with excitement, as if they had just received a bonus!

"Broken shaft? What model?"

Tan Songren sat at the table, holding a large, steaming teacup in both hands, his eyes shining brightly.

"It seems to be from a JY-76 high-speed vertical milling machine. The spindle is broken, and the machine is stuck there."

"...Because the original supplier went bankrupt, the shaft seat broke and no one dared to touch it. The factory didn't have any drawings or test pieces, so it's been sitting like this until now."

At this point, Chen Luyang added:
"However, after careful inspection, I found that although the fracture surface of that batch of bearings was rough, with a clear thermal fatigue band and some skew, the key structural parts were still intact."

"The keyway, screw hole, and limit groove at the interface are all well preserved. As long as we refer to the remaining drawing and deduce the dimensions of the main hole and the positioning fit, it should be relatively easy to proceed."

No sooner had he finished speaking than Liu Kangwen slammed his hand on the table.

"all!"

Tan Songren was so excited that he slammed his teacup on the table.
"Yes, this has to be done!"

Zhang Guoqiang sat up straight.

"We've spent our whole lives working on lathes, and now we're dealing with repair parts every day. It's making our brains rust."

"Now I finally have some decent skills to do!"

Tan Songren said, "Besides, it's fine if we have the blueprints, but it's even better if we don't. We can handle the dimensions and the precision!"

Every master craftsman in the machine factory has some unique skill.

Listening to Zhang Guoqiang and the others talking back and forth, several Peking University students couldn't sit still any longer.

"Xiao Chen, can we go?" Lin Qiming asked.

Although the fractured bearing is not very relevant to the topic of "fatigue crack modeling of connectors".

But you're a mechanics student!
With something readily available... how could I resist taking a look?!
“Yeah, Xiao Chen~” Zhang Nan couldn’t sit still any longer.

He's almost obsessed with drawing every day now.

Hearing the words "remaining drawings" or "making parts" is like stepping on an electric shock; all my nerves and thoughts snap up.

“I’ll go with you and help with the drawings, which will make it easier for everyone to get the work done.”

Damn it? !
Chen Luyang scratched his head, looking at the group of elderly men and senior students who had volunteered to join the fight.

"No problem!!!"

"That's definitely no problem!"

Let's go together tomorrow!

……

The next day

When Chen Luyang led the experienced repairman and a group of Peking University students into the machining warehouse with great fanfare,
Third Sister almost thought Cao Gai had colluded with the enemy and brought in bandits.

Upon entering the machine shop's warehouse, Lin Qiming and his students seemed to have stepped into the Bolsheviks, their eyes burning with fervor.

"This thermal fatigue layer... is quite typical."

Lin Qiming stroked the bearing seat with deep affection, his emotions so intense they seemed to overflow.

A group of people first carefully examined the several broken shaft seats from top to bottom and left to right, drawing diagrams and taking measurements as needed.

After collecting the initial data, the group of people fluttered into a flower garden like butterflies.

On one side, someone was lying on the ground examining the rusty worm gear housing; on the other, someone was taking out a small flashlight and a magnifying glass to look at the broken lathe spindle tail coupling…

The third sister frowned as she watched.

Those who knew better would think this was a group of scavengers that Chen Luyang had found.

Lin Qiming and his friends were happily "collecting scraps" over there.
On the other side,
Zhang Guoqiang, Tan Songren, Liu Kangwen, and Zhang Nan walked around the old bearing seat for a while. Without saying much, they each took out a tape measure, calipers, and paper and pen from their pockets, squatted down, and started working.

Zhang Guoqiang is a man of few words and decisive action. He can tell the baseline and the matching parts with just a glance. Based solely on observation and touch, he can "peel out" the dimensions bit by bit by following the structure of the parts.

Tan Songren, with his extensive experience, could tell from the fracture surface that the original material for the bearing seat had been chosen incorrectly that year, being three degrees too soft, a typical deviation in process settings.

Liu Kangwen focused more on the precision of the fit. After estimating the eccentric wear around the bearing, he immediately wrote down the circular runout error.

The third sister watched from the side with her eyes wide open.

As for Zhang Nan, she was even more remarkable!

Lately, he's been spending all his time at the repair shop taking apart parts and drawing blueprints, and his skills are improving by leaps and bounds.

The team worked together seamlessly, measuring, drawing, and analyzing. After a series of steps, they quickly got the key data pretty much right.

When it was time for them to leave, Lin Qiming and his group felt even more uncomfortable than when they left home, wishing they could touch every single part in the warehouse before they left.

If Chen Luyang hadn't repeatedly emphasized that this was someone else's home...

Several people even considered sleeping on the floor and staying there permanently.

With the basic data and drawings, the materials became much easier to obtain.

Jiaolong brought in a batch of materials from outside, and they're currently piled up in the warehouse, just in time to be used.

Late night
Outside the repair shop, heavy snow was falling.

Inside the repair shop, Zhang Guoqiang and a group of workers were working enthusiastically around the lathe!

Speak the truth,

These experienced workers in the factory are usually the ones who tackle the toughest challenges.
It's a waste of his talents to spend all his time at the repair shop fixing cars.

Now that they finally have a big piece of equipment to show off their skills, the group is acting like they've just discovered a new kind of feast.
It's so addictive!!!

It's so addictive!!!

There was absolutely no sign of fatigue on his face.

Restoring the broken shaft seat of the JY-76 milling machine, even with the best craftsmanship and the most complete equipment, is not a task that can be completed in "one or two days".

Even if several masters work at full capacity, it will still take about 7 days.

Seeing that she couldn't find the materials right away, Chen Luyang rushed back to school.

Although the repair shop matter was urgent, schoolwork was not easy either.

Chen Luyang has fallen behind in many classes because she missed school for the past two days.

The moment Chen Luyang shouldered her schoolbag and walked towards the school!

A thick, dark, and unsettling cloud slowly drifted back over the heads of all the freshmen at Peking University. In the past few days...
Chen Luyang took on three opponents at once.

With one's own strength,
They forcibly combined the departments of economics, philosophy, and mechanics to work on a project.
Furthermore, it was included in the list of "Municipal-level University Student Engineering Practice Base" projects by the Municipal Science and Technology Commission.

The news spread throughout the entire school.

Just as everyone was filled with envy, admiration, and mixed emotions, they waited anxiously for Chen Luyang to appear in the classroom and become the center of attention!
In the end, the person never showed up.

Even students who are eager to hear news don't need to ask.

After the teacher finished taking attendance, she openly and frankly told everyone:

Chen Luyang was granted flexible study schedule by the school, and could arrange her own coursework without mandatory attendance.

Damn it! ! !

Hearing this, the students in the class were truly speechless.

They studied diligently day after day, burning the midnight oil, and dared not miss a single class, for fear of missing this rare learning opportunity.

And now,
Chen Luyang!!!
Not only can you skip classes,

They can also take physical projects to factories, appear in newspapers, take photos, and attend various off-campus research meetings.

In an instant!
The wind—whoosh, whoosh!
Lei~ Chakuku, Chakuku!
The rain is pattering down, then pouring down!
Lei~ Kuchachiri Kacha!

This feeling of dark clouds looming over the city, like a storm cloud pressing down on everything.

This feeling of oppression makes even breathing difficult!

Just like the Five Finger Mountain pressing down on Sun Wukong,
It leaves no hope of turning things around!

But if you think about it more positively...

Sun Wukong was imprisoned under the Five Finger Mountain for 500 years.

And they only need to be suppressed for 4 years!
……

At this moment, Chen Luyang, completely unaware of the psychological trauma she had caused her classmates, got off the bus and walked into the campus.

The thick cotton boots hadn't even had a chance to roll over the puddle of snow at the intersection.
Chen Luyang was immediately drawn to the new decorations at the school.

The display windows in front of the teaching building, which used to be filled with exam notices and lecture announcements, have now been replaced with black, white and red promotional boards.

The signboard was printed with the words "A True Record of the December 9th Student Anti-Japanese National Salvation Movement," and next to it were old photos of young students wearing cloth shoes and hemp ropes and holding banners.

Walking along the main road, one after another, display windows spread out from the Arts and History Building to the Science and Education Building, like a long historical scroll.

All the essays written by students from each department were posted on it.

Some talked about national righteousness, some about the responsibilities of youth, and some wrote about serving the country with fervent passion.

In particular, there is a huge wooden sign standing in front of the library.

Eight characters were written in black and white on the paper:
"The awakening of youth has stirred up a storm."

On the tree trunk next to it, there was a small note that read, "The wind and thunder stir the youth's ambition, and the iron shoulders bear the soul of the nation."

Even the school's public address system was playing "Defend the Yellow River".

Chen Luyang stood on the still-melting snow, listening to the powerful and stirring melody. In an instant, she felt her blood boiling along with the music.

As Chen Luyang walked slowly forward, her eyes were drawn to a display case featuring "December 9th Historical Materials".

An entire wall was covered with clippings, photos, photocopies of old periodicals, poems by martyrs, and all sorts of historical materials from that time, which were carefully and meticulously pasted on it.

In the very center is a wide-format old photograph.

In black and white, thousands of people wearing cotton-padded military coats raised their arms and shouted slogans, surging in the sea of ​​people outside the East Gate.

There was also someone nearby who had compiled a map showing the coordinated responses to the December 9th Student Movement in Hongjin and Huahai, connecting them with red lines. The map was drawn meticulously and clearly the work of a history major.

Chen Luyang looked down at the signature:
"Showcase materials: coordinated by the External Relations Department."

It really was Shen Fei who came up with it!
Niubi!

Chen Luyang couldn't help but give Shen Fei a thumbs up in his heart.

Although that bastard Shen Fei usually makes them do chores and promises them empty words.

But it must be said that they can really pull out something good at crucial moments.

After looking through each shop window, Chen Luyang's toes were numb from the cold. She wiped her runny nose, turned around, and ran back to the teaching building.

He missed a lot of classes these past two days and needs to hurry back to find his classmates to copy their notes and catch up on what he learned.

As soon as I got upstairs,

From afar, Chen Luyang could hear a commotion coming from the classroom.

What are you discussing?

Chen Luyang pushed open the door and walked into the room.

"Among all the classrooms I passed by, our class was the noisiest."

Almost instinctively,

The entire class turned to look at Chen Luyang, their eyes filled with indescribable emotions.

"Wenwei, why do I hear the way you're talking? It sounds like a homeroom teacher on patrol!" Zhao Legen, the chubby butcher, wondered.

hehehe~
Chen Luyang, smugly taking advantage of her classmate, grinned in a way that made her want to punch him. Just as she was about to find an empty seat, Gao Xiaolin shouted in a loud voice:
"It's perfect timing that the Cultural Committee is back! I think we should let them handle this matter, no problem!"

These words were like igniting a bomb.
The entire class immediately erupted in excitement.

"Yes! Let the Cultural Committee handle it!"

"This matter needs to be handled by the Cultural Committee!"

"..."

Chen Luyang's smile froze, and a bad feeling welled up in her heart.

"Why do I have to do everything?"

What are you all discussing here?

Zhang Dongliang, a member of the Literature Committee, explained with a smile: "Xiao Chen, isn't it almost December 9th? The school has asked each department to produce a special bulletin board."

"Our economics department is also divided into several sections."

"The department assigned us freshmen to be in charge of three sections, but we couldn't come up with a solution after discussing it for a long time. Luckily you're back, so we'll leave the cultural committee work to you!"

Chen Luyang: "...?!"

wipe!
You came back just in time!
I should have known he would stay at the repair shop for two days before coming back.

However, setting up the bulletin board isn't a difficult task.

"What theme are required for the bulletin board?" Chen Luyang asked.

"Youth, patriotism, history, and contemporary responsibility," Jiang Feng began.

"The philosophy department set up a whole red and white display board, with short philosophical sayings about the nation, reason and responsibility written in calligraphy."

"The engineering school drew a huge blueprint for a gear, inside which was a hand clenched into a tight fist, with the words 'Technology saves the nation, youth are promising.'"

"The Foreign Languages ​​Department has the most elaborate designs!"

“We directly made the international students write ‘Looking at December 9th from an international perspective’ and posted a row of ‘Anti-fascist, anti-aggression’ slogans written in different languages.”

Listening to this, Chen Luyang couldn't help but exclaim, "I must say, they did a really good job!"

"That's right," said Luo Jianmin, a doctor from the medical team.

"I heard that the second-year students designed a project called 'National Economy and People's Livelihood,' which directly listed the old accounts of the student strike in 1935 to protest against Japanese goods and refuse to pay exorbitant taxes, and also posted several rice price lists from that year."

"The junior student designed a whole exhibition board that linked workers, peasants, students, and soldiers, showcasing the deeds of young people from central Hebei who went to the countryside to provide support, deliver medicine, and provide food,"

"We freshmen haven't made any moves yet."

Chen Luyang frowned slightly.

Compared to other disciplines, the Department of Economics is indeed lacking in boosting morale and inspiring a sense of responsibility.

After all, the mathematics department can participate in various large-scale national projects, and the mathematics department is behind every major national achievement.

However, although the economics department also has figures, they are often hidden behind the scenes and in ledgers, invisible and intangible, lacking the momentum to rally people.

That's why the students in the class discussed it for a long time but couldn't find a good starting point.

Chen Luyang thought for a moment and then said, "That's easy!"

"Didn't the school require the bulletin board themes to be youth, patriotism, history, and contemporary responsibility?"

"Then let's use 'ledgers and iron heels: national crisis and youth responsibility from an economic perspective' as the title,"

The main message of the promotion is:

"Amidst the flames of war, young people are not only passionate advocates, but also calm analysts and steadfast builders."
