Back to the 80s Machinery Factory

Chapter 135 I’ll treat you to stewed beans at our old restaurant later
Chen Luyang was muttering in his heart,
Turning around, Zhu Jifei looked at him with a "kind face".

"Son, is it too hot to wear a sweater today?"

Chen Luyang: ...

He should have listened to his mom yesterday and not worn this sweater today!

But Chen Luyang still said cheerfully:

"It's okay. It's cool in the morning and evening."

Zhu Jifei: "You know the difference between cold and heat, better than your dad!"

"Come on, I'll take you to our production workshop!"

……

Zhu Jifei and Huo Da led Wang Qingzhou and his party to visit the largest production workshop of the engine factory.

As soon as he entered the big iron door of the workshop, the clanging sounds and noisy roar of machines reached Chen Luyang's ears.

On the wall close to the gate, there are densely packed certificates and awards hanging.

Among these awards, in addition to collective awards, there are also many personal certificates for "Xu Qingsong".

Chen Luyang subconsciously looked at those certificates.

As he watched, Chen Luyang became amused.

This is not Xu Qingsong,
Isn’t this Xu Laoer!
Comrade Xu Qingsong,
Second place in the provincial technical workers competition in 1971.

Second place in the provincial technical workers competition in 1972.

Second place in the provincial technical workers competition in 1973.

Second place in the provincial technical workers competition in 1974.

……

Chen Luyang looked at them one by one.

Except for 1975, when Xu Qingsong won the first place,
He was the runner-up in all provincial technical workers' competitions.

In an instant, Chen Luyang felt extremely deep sympathy and strong curiosity towards this unfortunate "Second Brother", and was extremely eager to see this "Number Two Hero"!
Just at this time,

Several workshop workers came towards them.

The leader was a tall man about the same age as Chen Dazhi.

His clothes were stained with engine oil, he was wearing work gloves, and there was also a small towel stuffed in his collar for wiping sweat.

Maybe he just finished his work.

The sweat on the man's face flowed down his cheeks.

Seeing him, Chen Luyang thought of his father again.

Damn, it hurts!
In the evening, I bought some wine and peanuts and took them home to honor Lao Chen.

This person obviously knows both Wang Qingzhou and Yu Anshan.

As soon as we met,

Wang Qingzhou smiled and said, "Master Xu, we are sorry to bother you with your work today."

The tall master grinned and said honestly, "It's no bother at all. We have always wanted to come to your factory to learn, and today is the perfect opportunity. Please give us some guidance, Director Wang."

Saying,

The tall worker looked at Chen Luyang behind Wang Qingzhou with some surprise.

This young man is so young and yet he can go out with Wang Qingzhou, he must be extraordinary.

It seems that...I am not feeling well?
Why are you wearing a sweater today?
Normally, although Chen Luyang is good-looking, his appearance is always lowered when he puts on work clothes, and he doesn't look so outstanding.

But this black sweater that Chen's mother knitted for him today,

It directly suppressed the young man's slightly impetuous and lively side, making his whole temperament have a sense of calmness and peace.

Against the backdrop of this plain color, the young man's beauty and elegance are immediately highlighted.

The tall worker's first reaction was that Chen Luyang might be the child of a leader, and he laughed:

"This guy has a lot of clothes on!"

Chen Luyang smiled on the surface, but he was stabbing himself in the heart like crazy, wishing he could stab himself to death this morning.

Zhu Jifei was amused: "Old Xu, this young man is a senior technician in the machinery factory."

When the tall worker heard the word "senior technician," his gaze darkened and became more formal. To be a senior technician at such a young age, he must be quite an exceptional person!
However, before he could react,
Zhu Jifei then spoke.

"You know his father too."

"Who?"

"Chen Dazhi."

……

moment!

The air was silent.

The tall worker glared at Chen Luyang, which made Chen Luyang's heart tremble!
What the hell are you doing!

Are you trying to eat people?
Why did this person react so strongly when he heard Lao Chen's name?

Based on the principles of retreating to advance, not hitting those who smile, modesty is beauty, and respecting predecessors,

Chen Luyang decisively extended his hand and said warmly and humbly:

"Hello, Master Xu. My name is Chen Luyang. You can just call me Xiao Chen."

"My name is Xu Qingsong."

The tall worker gritted his teeth.

Chen Luyang: ???

Yo, hero number two?!
Originally, Chen Luyang thought that it would be over after shaking hands, but Xu Qingsong's hands kept squeezing tighter and tighter.

The workers in the workshop are strong in their hands.
In the end, Chen Luyang felt like he was struggling with a pair of pliers.

Fortunately, the other party showed mercy and stopped in time.

Chen Luyang hid his hands, which had turned white from being pinched, behind his back and rubbed them gently.

I muttered to myself:
If I have the chance next time, I will take you to the old restaurant to eat stewed beans!

……

After the previous episode,
Chen Luyang stood obediently behind his factory director and accompanied him on a tour of the engine factory's workshop.

"Recently, our factory has undergone technological reforms and achieved technical breakthroughs in addressing two major difficulties: cylinder bore deformation and crankshaft bore diameter and coaxiality."

“By adopting high-roundness cylinder bore machining technology, a dummy cylinder head is installed on the cylinder block while the cylinder bore is being machined to provide equivalent cylinder head bolt load and cylinder head gasket surface pressure, thereby reliably suppressing cylinder bore distortion after cylinder head installation.”

"At the same time, a combination of roughing, semi-finishing and finishing is used, and crankshaft hole reaming and honing is added to meet dimensional accuracy requirements."

In the workshop,
Xu Qingsong led Wang Qingzhou and others on a tour while introducing them.

Chen Luyang followed behind.

With the mentality of stealing the skills, he memorized every word the other person said.

I wish I could memorize all their techniques and tell them to Lao Chen when I get home.

Here he is remembering,

Xu Qingsong led them to a lathe.

“Before, we didn’t have the equipment to cast the cylinder body, so everything was done purely by hand using high-pressure and low-pressure casting.”

"Now that the factory has a cylinder boring machine, the problem has been easily solved."

Chen Luyang still has an impression of this machine tool.

Previously, at the National Machinery and Heavy Machinery Exhibition, Pianercheng No. 1 Machine Tool Factory produced the country's first CNC cylinder boring machine.

According to the introduction,

This machine is capable of performing various drilling and boring operations, as well as rolling, using either internal or external chip removal. The machine bed offers strong rigidity, excellent precision retention, a wide spindle speed range, and an AC servo motor-driven feed system, adapting to various deep-hole machining processes.

I didn't have time to look carefully before.

Now that he has the chance, he must take a good look!

Watching it.
Suddenly Xu Qingsong looked at Chen Luyang and asked with a smile:

"The main method of fixing the cylinder liners and cylinder blocks of engines currently produced in the factory is still mechanical fixation such as pins and expansion sleeves."

"I wonder if Technician Chen has any good ideas on how to better achieve stability and tightness in the fixation. Could you give us some advice?"
