In the evening, Duan Yun went to the night shift as usual.

After an hour of manual processing, seeing that the band leader was not there, he continued to plan to install the components and carry out automatic processing.

However, as soon as Duan Yun opened the tool cabinet, he found that something was wrong.

It turned out that when he cleaned up his workstation two days ago, the servo motor had always been placed at the bottom and innermost, but now it was placed at the front.

Obviously, his toolbox must have been tampered with.

Duan Yun quickly checked the other things in the box, and was relieved when he found that no workpieces were missing.

In fact, Duan Yun is not worried that others will find these things in their cabinets, because almost everyone in the workshop has more or less 'private goods' in their tool cabinets, but as long as they don't take out the factory, it is not a violation of factory regulations, so Duan Yun estimates that maybe it's just that other workers saw that the door of the box was not closed, and looked at the things inside out of curiosity.

Relieved, Duan Yun quickly assembled the workpiece on the lathe and began today's automatic processing.

Standing aside and staring at the machine a little bored, Duan Yun took out his drawing book from the box again, and was going to design a modified sketch of an automatic gear hobbing machine tonight.

It's just that when Duan Yun turned the book to the middle, he found that two pages of paper had been torn off.

Duan Yun clearly remembers that these two pages were the sketches he had drawn earlier about the modification of this lathe, and the dimensions and three-dimensional renderings of the various components he needed were also marked.

This immediately aroused Duan Yun's vigilance.

In Duan Yun's opinion, these two pages are likely to have been ripped away by someone who is knowledgeable about machinery, because in this book, in addition to these two pages of specific marking diagrams, the other pages are drawn with some calculation formulas and sketches of parts without any data, which has no reference value.

In a workshop, basically any skilled lathe, including a technician, can understand this kind of mechanical drawing, so Duan Yun is still not sure who stole these two pages of sketches.

But soon, the corners of Duan Yun's mouth curled up.

The reason is very simple, these two pages of drawings are the original modification drawings designed by Duan Yun at the beginning, but at that time, Duan Yun did not consider it sufficiently, the design of some parts was unreasonable, and the specific size parameters of some parts were not accurate, without taking into account the degree of wear and tear of the machine in recent decades, and the real modification drawings were memorized in his own mind, and those two drawings were actually useless!

And if you take those two drawings for lathe modification, it is possible to cause some serious mechanical failures and even accidents that damage the original lathe!

There is also the fact that Duan Yun has already left a hand before, and he did not put all the modified workpieces in the toolbox, among which there are three key pinion parts that link the bearing, which are placed at the bottom of the toolbox on the ground only two fingers wide from the ground, which is difficult for ordinary people to notice.

Duan Yun knew that there was no impermeable wall, and it was only a matter of time before others found out about his modification of the lathe, so he also left a hand early to avoid making a wedding dress for others with his own efforts.

In addition, Duan Yun is essentially a person who does not profit and does not get up early, and he also knows that there is no patent in this year, if the factory does not give him enough benefits, then he only needs to hide these three key parts, and it is impossible for the lathe to achieve automated production.

This is the same as Duan Yun's previous practice of installing an anti-piracy device on his antenna.

Picking up the pen, Duan Yun began to conceive of the drawings of the gear hobbing machine again......

......

When it was time to take over in the morning, Duan Yun put the processed more than 700 columns into the warehouse, changed his clothes and left, just like yesterday.

At the same time, after Tian Feng, who had just taken over the morning shift, changed his clothes, he did not go to the workshop to wander around, but came directly to the direct office.

Opening the data cabinet, Tian Feng took out a half-drawn drawing from it and laid it flat on the desk.

Standing up and locking the office door, Tian Feng took out a folded piece of paper from his pocket.

These were the two sketches torn from the notebook in Duan Yun's tool cabinet.

Picking up the compass and the ruler, Tian Feng looked a little excited on his face, and carefully perfected the remaining sketches against Duan Yun's two sketches......

......

At half past twelve in the afternoon, after Duan Yun had lunch, he rode his bicycle to the place agreed with Cao Dong, who grabbed the tortillas, last night.

"It's early. Seeing that Cao Dong was waiting there early, Duan Yun greeted with a smile.

"You said yesterday that you would find me a job, does it count?" Cao Dong obviously Duan Yun didn't have any sense of trust yet, but he really didn't have any other means of making a living now.

"If I didn't count, I wouldn't be here today. Duan Yun pouted and said.

"What the hell is the job?"

"Don't worry, it's definitely not illegal. Duan Yun took out a cigarette and lit it, took a puff and said, "And it's definitely more than the average worker in our factory!"

"Just don't break the law. Cao Dong nodded and said, "But I have two conditions. ”

"Say it. ”

"First, you should give me some advance salary first!Second, I haven't had lunch yet......" Cao Dong hesitated and said.

"No, what about the cake I gave you yesterday?" Duan Yun asked with a frown.

"I finished eating ...... in the morning"

"You ate all the tortillas from last night to this morning?" Duan Yun was stunned when he heard this, and then said, "That's more than twenty tortillas!"

"I'm done. ”

"Okay. Duan Yun could see it, and it was estimated that this Cao Dong must have been hungry for a long time before he met him last night, so he said, "Then let's go, I'll take you to lunch." ”

"Hmm. Cao Dong nodded when he heard this, and followed behind Duan Yun.

Walking to the street of the factory, Cao Dong's eyes immediately looked straight at the stall selling boiled corn and cakes on the side of the street, while Duan Yun led straight to the only state-owned restaurant in the factory.

"Brother, this place is expensive, so you can make do with it on the side of the road. Cao Dong saw that Duan Yun was about to enter the hotel, and hurriedly whispered.

For later generations, it is a very rare and ordinary thing to eat in a restaurant, but in the early eighties, meat, grain and oil, eggs, etc. are all available in limited quantities.

"You're a kind person, and you actually want to save me money. Hearing this, Duan Yun patted Cao Dong's shoulder with a smile and said, "Don't worry, you can't eat me for a meal." ”
