Back to the 80s Machinery Factory

Chapter 424 Senior Engineer Can't Draw Blueprints? ??

Amidst the heated discussion in the Literature and Art Department, a triumphant roar also erupted in the External Relations Department.

"It's stamped!"

Shen Fei strode in, holding an invitation stamped with the red seal of the Youth League Committee, his face beaming with the smug satisfaction of a great success.

"Both have been approved?" Ma Tieli looked up in surprise. "So fast!?"

"Of course!" Shen Fei plopped down at the table, waving the invitation in his hand triumphantly.

"Teacher Wang from our Youth League Committee, huh? What a difficult person to deal with."

"Looking at our invitation, with its eyebrows and eyes that don't look like eyebrows or eyes, I just want to find something wrong with it."

"In the end, they couldn't find any mistakes and just stamped it on us!"

Shen Fei looked at the invitation letter in his hand with delight: "Xiao Chen's invitation letter is so well-written, not a single word is wasted! It's enthusiastic where it should be, and politically savvy where it should be. Even the salutation is more professional than ours. No wonder I said you have great potential to be a ministerial candidate!"

After praising Chen Luyang, Shen Fei turned to praise Huang Fugui from the Chinese Department.

"The letters that Fugui wrote to several teachers in the school were also quite well written, with a grand style and elegant handwriting. You can't deny that he studied Chinese literature."

Huang Fugui was a little excited by the praise: "Minister, what do we do next?"

"The following matters are extremely important!" Shen Fei entered a state of "overall planning".

"Fugui, go to the general affairs office later to register and borrow a megaphone, and also register three emergency kerosene lamps. In case there is a power outage on the day of the lecture, we can't let the speaker read the script in the dark."

Huang Fugui's eyes gleamed: "Great!"

"Tie Li, tomorrow, take the approval slip from the Youth League Committee and go to the school office to get a batch of white tea mugs with lids. Then go to the labor union and find Xiao Banfa to get a template to paint the four red characters 'Science Spring' on them."

"After that, pick out a few cans of the jasmine tea that weren't given away last year, and send them to the lecturers along with a jar."

Ma Tieli rolled her eyes, indicating that she was listening.

"By the way, there's one more thing."

Shen Fei said, "All our student staff will have an extra meal on the day of the lecture! Each person will receive a braised ribbonfish voucher!"

"I'll fill out the application form at the cafeteria and submit the list to the Youth League Committee's publicity group for approval. Once the approval is issued, Tie Li, you can go to the General Affairs Office cafeteria window to redeem the vouchers."

Ma Tieli spoke softly, "Comrade Shen Fei, can't you be a little more considerate... and treat me like a female comrade?"

Lesbian?

Shen Fei looked at Ma Tieli with surprise.

Chen Luyang and Huang Fugui also subconsciously shifted their gaze.

To be honest... Ma Tieli is quite good-looking.

She has the bold and spirited look of a northern girl, with big, bright eyes.

But that's just how it is... her personality often makes Chen Luyang and the others forget that she's a girl.

I always felt like he was the older brother.

Fortunately, Shen Fei reacted quickly and immediately said:
"Tie Li! You're not just a female comrade, you're a key member of our External Relations Department!"

"You single-handedly hold up half the sky of the External Relations Department. Our department can do without anyone else, but we can't do without you."

Ma Tieli rolled her eyes at him.

"Shut up, you're giving me a headache every day."

Shen Fei chuckled: "Okay, okay, I'll shut up, I'll shut up."

After arranging the work for Huang Fugui and Ma Tieli,

Shen Fei turned to Chen Luyang and said, "Xiao Chen, go to the home of a researcher at the Chinese Academy of Sciences on Saturday to deliver an invitation."

"I've already asked for the address; it's in the residential area near the experimental building of the Second Branch of the Chinese Academy of Sciences."

Chen Luyang asked in surprise, "Didn't we agree that you would come with me?"

Speaking of this, Shen Fei's face was filled with anger:
"It was originally supposed to be just the two of us!"

"But the student union talked to me this morning, saying that I didn't attend last year's recruitment meeting, which had a very bad impact on the student union, and they gave me a lecture."

"They said I have no regard for organization or discipline, and that I'm detrimental to the unity of the student union. If I don't show up again this year, they'll criticize me and make me write a self-criticism."

When this was mentioned, Shen Fei rolled his eyes so hard they almost flew to the sky.

"So this task can only be entrusted to you!"

Shen Fei sighed softly.

"This is your first diplomatic mission since joining the Foreign Liaison Department, do a good job!"

Chen Luyang: ...

Shen Fei looked at the three people in the room and said with deep emotion:

“Before, there were only two of us, Tieli and I, causing trouble. Now that we have more people, we can finally get things moving.”

Chen Luyang wondered, "Why are there so few people in our External Relations Department? I see the Arts and Literature Department is packed with people."

“You just arrived and don’t know,” Ma Tieli said with a helpless expression.

"The job of external liaison is not easy. You have to run around for everything, write documents, move equipment, and listen to the teacher's lecture. It's tiring and thankless."

"People are initially drawn to the novelty and sign up, but after two weeks, most of them have already left."

As she spoke, she glanced at Chen Luyang and Huang Fugui and said with a hint of melancholy, "I wonder how long you two can stay here."

Shen Fei was displeased: "What kind of discouraging talk is this! These two are key members of our External Relations Department!"

Turn your head,
Shen Fei spoke to Chen Luyang and Huang Fugui in a soft, gentle voice, as if coaxing an old man:
"Let's not listen to that nonsense. I'm telling you, if this event is a success, I'll give you rewards."

Just as Chen Luyang and Huang Fugui were looking forward to their reward,
Shen Fei declared with great enthusiasm, "You two each get one extra meal voucher from the cafeteria!"

Chen Luyang's lips twitched.

He finally understood that Shen Fei didn't have anything good to offer.

"Okay!" Shen Fei clapped his hands.

Let's all work hard and do our best!

……

The next day at noon, Chen Luyang, carrying a bag and holding the hand-drawn blueprints by Zhang Guoqiang and his team, knocked on Zhang Diancai's office again.

"Teacher Zhang, these are the handcraft drawings made by our workers. Please take a look."

Chen Luyang carefully spread a stack of handmade drawings on the table, her movements somewhat tentative.

He came prepared to plead and beg three times.

No matter what, he was determined to get Zhang Diancai to draw him a blueprint!
Zhang Diancai picked up the top spark plug breakdown sketch.

The paper was old-fashioned coarse straw paper, and the rulers and dimension lines were drawn with a pencil.

Although the lines are irregular and the dimensions are slightly off, the overall layout is surprisingly clear.

The side is also covered with markings such as "Assembly clearance 0.2", "It is recommended to process the universal adapter section according to the maximum value, and the deviation will be compensated by the washer", etc.

Zhang Diancai had only casually flipped through the pages when he saw these few strokes, and suddenly clicked his tongue, a hint of surprise in his eyes.

"Are you planning to make one structure compatible with three different models?"

"With different dimensions and varying operating conditions, will this structure be suitable?"

"It's possible!" Chen Luyang answered readily.

“We dismantled dozens of old parts in our workshop. The structural differences were basically within a few millimeters. Several experienced workers discussed it for several days, categorized the dimensions, set an intermediate value, and used washers to compensate for the difference. This way, we could assemble the parts without delay or have to search for them repeatedly.”

Zhang Diancai looked down and flipped through the pictures again, asking:

"Is the machining sequence of the inner hole marked on this diagram also the process you actually follow?"

“Yes.” Chen Luyang nodded.

“We tried three processing methods. This one is the most economical in terms of tools and is less prone to misalignment. It was decided after several masters checked it several times.” “Hmm.” Zhang Diancai nodded, then picked up another sketch and looked at it carefully.

"...This drawing may be rough, but the underlying concept is sound. The angles are well-distributed, and the labels are placed strategically; it was drawn by someone knowledgeable."

Saying,

Zhang Diancai opened the drawer, took out a stack of A3 standard drawings, placed the spark plug sample on the edge of the drawings, picked up his pen and drew a line, and a reference axis was accurately placed on the paper.

Am I stupid? ? ?

What's going on here?!

Chen Luyang stood there, momentarily a little excited!
He hadn't even used his usual tactics of "crying, making a scene, and threatening suicide" or "persuading and begging" to get close to her yet.

So, Teacher Zhang glanced at the sketch and immediately started drawing?
Happiness came so suddenly!!

Chen Luyang stood to the side, watching Zhang Diancai draw with an excited expression.

He truly deserves to be the man chosen by the military research institute.

That pencil... it's practically flying off the board!
The cutting of the threaded section, the geometric positioning of the insulator cone, the marking of the pressure line on the sealing gasket seat... each line is as if printed on paper, and even the chamfer annotations are directly marked with the angle and chamfer width.

If someone else were to draw this, they would have spent half a day just measuring the dimensions.

But Zhang Diancai used calipers to measure twice and sketched out the basic shape of the complete cross-section.

As he drew the diagram, Zhang Diancai also clearly wrote down the technical standards for the threaded section next to it.

“M14×1.25-6g”
"It is recommended to pre-drill holes with cold extrusion before turning, Ra1.6".

"The ceramic body is annealed before insertion, at 750°C, and then slowly cooled."

……

Tolerances, surface roughness, heat treatment process, and positioning datum are all written down.

These blueprints can be given to the workshop and immediately put into the blueprint cabinet for production.

...What did I tell you?!

Chen Luyang's heart screamed wildly.

The students' drawings are already so amazing, the teacher's work is simply incredible!

I'm so glad I came to Peking University; I have the opportunity to study and live under the same roof as such amazing people.

Otherwise, if you were to search blindly on your own, you don't know how many detours you would take!

Although it is an industrial drawing, a spark plug is, after all, a small to medium-sized structural component, not a complex assembly drawing.

In less than an hour,
On the paper, a standard industrial drawing was clearly formed.

Zhang Diancai carefully checked the blueprints again, and after confirming there were no errors, he said:

"This is just a baseline drawing. After you finish making it and bring back the sample, I will provide tolerance and fit drawings and process supplements."

Chen Luyang nodded frantically.

"...Teacher Zhang, you're amazing!"

Zhang Diancai stopped writing, gently placed the pencil on the edge of the paper, and without even looking at him, said only one sentence:
"You don't need to flatter me. This is the only picture I can draw for you."

"...Huh?" Chen Luyang's newly formed emotions were instantly deflated.

"I've been so busy with projects lately that I really don't have the time," Zhang Diancai said.

“I have a student named Zhang Nan. Give him the remaining two drawings and tell him to draw according to the standard of this drawing.”

"……Fine."

Although reluctant, Chen Luyang knew that with Zhang Diancai's skills, it was already a huge favor that he could spare the time to draw one.

As for what happens in the future, we'll talk about that later.
The main focus is on a slow and steady approach!

Just as Chen Luyang was carefully wrapping up the industrial blueprints, Zhang Diancai suddenly spoke up.

"You said you were a trainee from the provincial machinery factory?"

"Yes, teacher, what's wrong?"

Chen Luyang answered instinctively.

Zhang Diancai looked him up and down: "You're a sponsored student and you're in charge of the car maintenance and repair center in Pian'er City, so you're not an ordinary person in the provincial machinery factory, are you?"

hiss……!!!
at this time!

now!!!

Chen Luyang decisively retracted her previous prejudice against science students.

Who says science students can't chat or talk?!

Look at other teachers, they always focus on the key points.

"Teacher Zhang, I am the director of the rubber workshop in our factory."

It's been a while since I've flaunted my status, so I'm a little excited to suddenly say it out loud.

Zhang Diancai raised an eyebrow and looked Chen Luyang up and down again.

"Wow, that's impressive! Workshop foreman... So what's your professional title?"

What a question!
It was like poking at the softest and proudest part of Chen Luyang's heart, making him tremble all over.

"Teacher, besides being the workshop director, I am also a senior engineer in our factory."

Even though Chen Luyang had tried his best to control himself, his eyebrows still couldn't help but twitch wildly.

But before he could even be happy for another minute,
Zhang Diancai's words punctured his smug bubble.

"How could you, a senior engineer and workshop director at a provincial machinery factory, not know how to draw?"

Zhang Diancai looked at Chen Luyang with a hint of suspicion in his eyes.

Holy crap...!
Chen Luyang's smile froze on her face.

“Teacher Zhang… my situation is a bit special. I am a senior translator at our factory.”

Zhang Diancai chuckled: "You're a senior translator?"

Chen Luyang quickly clarified, "I translated all the Japanese and Italian materials for our factory's car manufacturing."

"I also translated Samuelson's original economics book, which is part of our department's curriculum."

"The cassette tape of 'Practical English Communication Handbook' published by Peking University Press was written by me."

In an instant, Zhang Diancai's gaze deepened.

Chen Luyang's legs trembled.

Be obedient...

The Department of Economics and the Department of Philosophy are currently working on a project to translate the original texts.

Surely the mechanics department shouldn't have this kind of program?

Although having many skills is never a bad thing, his arms really can't carry too many mountains.

Fortunately, Zhang Diancai's gaze only deepened for a moment before he waved for people to leave.
"I'll write a note. Take it to Zhang Nan in the lab building and ask him to draw the remaining two diagrams for you."

Saying,

Zhang Diancai pulled out a blank sheet of practice paper with only one sentence written on it:

"Draw the blueprints according to this standard."

After tossing the note to Chen Luyang, Zhang Diancai got up, packed his things, and hurriedly prepared to leave.

"I have to rush to the teaching and research group meeting. You can handle the rest with him yourself."

Chen Luyang quickly took the note, said "Okay!" and slung her backpack over her shoulder, heading towards the laboratory building.
