Back to the 80s Machinery Factory

Chapter 432 You couldn't take it with you even if you worked yourself to death!

As Chen Luyang walked, he casually patted one of the items covered in grease:

“These all have usage records, mileage, and disassembly time.”

When I saw that whole row of large connecting rods, control arms, and damaged shock absorber columns, all covered in rust and with clearly visible cracks...
The look in their eyes was absolutely mad!
"Xiao Chen, can we take all of these with us?" Lin Qiming asked expectantly.

"Yes, we can! Absolutely!" Chen Luyang said readily.

"As long as you can take it, it's fine~"

When Chen Luyang said this, the corner of her mouth twitched almost imperceptibly!
He revealed a smile that said, "You can't take it away even if you work yourself to death."

Sure enough, after these words were spoken, the group fell silent.

If it were spark plugs or small connectors, that would be one thing.

With their numbers and strength, they can eventually carry it back.

However, the items inside are either broken shock absorber columns, large axle components, or neatly arranged old-style connecting rods weighing over ten kilograms each.

Don't say that there's strength in numbers.

Even if Old Man Yu Gong brought his sons and grandsons to carry it, it might not take him several years.

This is how to do……

Look at the expressions on everyone's faces—a mixture of silence, contemplation, and a rare hint of excitement!
Chen Luyang, who had been standing to the side stealing glances, finally revealed a kind and gentle smile.

The time has come!!
"As you can see, I have quite a lot of things, but the problem is that there are too many and they are too heavy to carry around. Every time you come, it's hard to get a car, which is not only wasteful, but also leaves no time to examine them closely."

“My place is quite big, and there are several empty rooms upstairs.”

"How about... you consider setting up this place as an experimental site for the Department of Mechanics at Peking University?"

Um? ? ? ?

Zhang Diancai looked at Chen Luyang in surprise: "You set up a point here??"

"Yes!" Chen Luyang said firmly and seriously.

“You set the research direction, and we provide the samples and on-site support; students come here to take measurements, draw diagrams, and write reports, so the research projects can be implemented.”

“And,” he paused.

"You come to provide project guidance, and the results will be registered under the research group's name. Whoever it belongs to, it belongs to."

This statement came out of nowhere.

Not only Zhang Diancai, Lin Qiming, and Zhang Nan, but even Director Lu and Zhang Guoqiang stared wide-eyed in astonishment.

Isn't this decision a bit too presumptuous?

Why does Chen Luyang always act on a whim?

Chen Luyang said with a smile, "Teacher Zhang, let's not rush to agree. You can go upstairs and take a look first."

“…Okay.” Zhang Diancai nodded thoughtfully and followed Chen Luyang upstairs.

This time, Zhang Diancai's expression carried a hint of scrutiny.

Although the repair shop is staffed by a group of men, they are all capable and efficient.

A group of people cleaned the house thoroughly, both upstairs and downstairs.

Overall, it turns out that two rooms can indeed be set aside as laboratories.

Zhang Diancai was slightly tempted...

pity.

The repair shop had many samples, but the equipment was subpar.

Although the repair shop also has a lot of equipment.

However, repair shops do not have machines such as rotary bending fatigue testing machines or high-frequency fatigue testing machines.

Moreover, the high-frequency fatigue testing machine in the laboratory alone weighs three tons and vibrates extremely strongly when running, requiring the addition of an independent concrete base and a shock-absorbing pad.

The maximum load-bearing capacity of the second floor of the repair shop is only 500 kilograms per square meter.

They can't even pass the initial testing stage.

But the repair shop's facilities are just too good!!!
The physical samples, damage data, disassembly records, and complete set of repair process documents in front of us can not only make up for the problem of "hollowed-out experiments" in the laboratory.

If used properly, it can accomplish something!
On the other side, Chen Luyang was not idle either.

Zhang Guoqiang, Tan Rensong, and Liu Kangwen, three experienced craftsmen, are carefully reviewing the improved blueprints.

Although this set of drawings is much more detailed and improved compared to the last one.

However, the engineers who draw the plans and the workers who manufacture them are never separate entities.

The two parties need to communicate constantly in order to get a machine or piece of equipment working properly.

While Zhang Diancai and a group of students were still wandering around upstairs,
Zhang Guoqiang gently pulled Chen Luyang aside and whispered:

"Director, could you bring that young man who drew the blueprints to the factory? Let them work it out on-site so we don't have to rework it later."

Chen Luyang, who also came from a factory background, understood what he meant as soon as he heard this.

"Okay! I'll go talk to him!"

After saying that, Chen Luyang moved closer to Zhang Nan and whispered:
"Senior brother, I have a favor to ask. Could you come with us to the processing plant so that you can show your drawings to the frontline workers in person?"

"To the processing plant?" Zhang Nan was taken aback.

"Yes," Chen Luyang said sincerely.

"The drawings you made this time are very clear, but even the most detailed drawings are only valid if they are put into practice."

"Why don't we take a walk around the site and see the actual processing conditions? We can clarify any problems on the spot, so we don't end up with a great drawing on one side and a crooked one on the other, wasting time going back and forth."

"This...?" Zhang Nan's tone was somewhat hesitant. What's there to say about this?

Just do whatever you're told, and you're done.
Besides, all my drawings are based on academic design standards.

The three views, sections, annotations, tolerances, and tool setting diagrams were all drawn clearly, so he couldn't explain anything.

Moreover, he came here for the research project, not for parts processing.

He wanted to decline, but Chen Luyang's mouth was just too damn good at talking.

He said, "Please, senior brother."

The other person said, "If you go once, we can reduce the number of batches that need to be scrapped."

With Zhang Guoqiang and Director Lu also smiling and offering words of encouragement, Zhang Nan felt embarrassed.

Under duress,

Zhang Nan, carrying a drawing tube filled with blueprints, went out with Zhang Guoqiang and Tan Rensong.

He didn't say anything, but you could tell from his expression that he was somewhat unwilling.

He was the top student in graph theory in the mechanics department, and even if his drawing skills weren't as good as Zhang Diancai's, he considered himself...

Yesterday, he redrawn the blueprints based on the parts sent by Chen Luyang.

Logically, there shouldn't be any more mistakes this time; the workers should just follow the blueprints to polish it.

But to his surprise, Chen Luyang still wanted him to come to the workshop.

But this "what am I doing here?" mentality was shattered the moment I stepped into the workshop.

Stepping into this "bulk" workshop,
A strong smell, a mixture of machine oil, iron filings, and hot air, hit him in the face. The sawtooth belt spun rapidly on the drive pulley, the lathe roared incessantly, and the cutting edge cut through the steaming metal, making a piercing "squeak-clang" sound.

Tiny iron filings floated in the air, landing on my nose and face, causing a burning pain.

Zhang Nan subconsciously took a step back, peering through his glasses to observe the entire workshop.

Since he came to Peking University to study and learn blueprinting from Zhang Diancai...

He had visited the experimental workshop of the school-run factory and accompanied his teachers on business trips to machine shops of other units.
But this was the first time he had ever seen a "family factory" like this.

Everything here seems so primitive, rough, and irregular.

The lathe is a C616 model from the 1960s, the power supply is an old-fashioned knife switch, and the drive belt makes a constant rattling noise.

The craftsmen circled around the workpiece, one foot on the operating pedal and the other hand holding the tool holder. Oil stains soaked their cuffs, and sweat streamed down their temples.

Upon seeing Zhang Guoqiang and his group, an experienced worker walked over.

"coming?"

"They've arrived!" Zhang Guoqiang introduced politely, "Master Wang, this is Engineer Zhang. He's the one who drew the previous blueprints."

"Hello." The old master wiped his hands and stretched them out in the air.

"Hello, hello." Zhang Nan quickly shook hands, but her face turned red.

Although that's what everyone calls me in the factory, I still feel a little embarrassed to be called "Engineer Zhang" when I'm a student.

Did you bring the blueprints?

Zhang Nan snapped out of her daze and quickly pulled out the newly drawn blueprints and cutting diagrams from the drawing tube, handing them over.

"This is a structure optimized based on the old part; I adjusted the groove wall thickness to 0.8..."

Before he finished speaking, the old master craftsman had already frowned.

"Your tank wall is 0.8?"

“Yes,” Zhang Nan nodded, her tone serious.

"This part is designed to reduce weight, and the stress area is not large. 0.8 is the optimal design. Any thicker would waste materials and may also cause assembly problems."

"I can't do it." The old craftsman shook his head decisively.

"Your drawing shows a tank wall thickness of 0.8mm, but our equipment can't make it that thin."

Can't do it?
Zhang Nan's expression froze.

The experienced craftsman explained, "This isn't a CNC machine tool; it's an old machine from the 1960s. When we turn it to this thickness, the cutting tool becomes unstable. The maximum thickness we can make for you is 1.2mm. Any thinner and you'll be waiting for the tool to break."

Zhang Nan frowned: "If it absolutely has to be 0.8..."

"Then you'll have to get us a new machine tool first."

The experienced worker's tone wasn't harsh, but one sentence from him completely shut Zhang Nan down.

That 0.8mm groove line was carefully drawn by him after checking three types of imported parts and comparing mechanical models.

He also thought that the lighter and more advanced it was, and the closer it was to international standards, the better.

But the factory couldn't make it!
However, Zhang Nan reacted quickly. Since the factory couldn't produce this thickness, he simply asked:
"If I modify this structure, and replace the tank wall with a stepped tank, can your machine handle it?"

The experienced craftsman pondered, "If you're making a stepped structure, we'll switch to a forming tool and run it through, leaving a 1.5mm thick shoulder. That should do it!"

Upon hearing that the plan was feasible, Zhang Nan immediately squatted down, spread the drawings on the bench next to the workshop, took out a pencil and ruler from her bag, and asked questions as she revised them:

"Master, how deep do you suggest this step be? How far can the knife go?"

The master craftsman said, "The most stable cutter head is 1.5mm, and the shoulder width should not be less than 5mm. Don't set a chamfer on this side of the lathe; I'll finish it manually."

"understood."

After Zhang Nan finished answering, he immediately found a replacement position in the structure and promptly added machining allowance, structural stress distribution adjustment points, and even proactively canceled the chamfer and adjusted the tool feed angle markings.

"You've got some skills!"

Zhang Guoqiang and Tan Rensong stood behind him, raising their eyebrows slightly.
