Speaking of which, the factory was really busy during this time.

In the past two years, the country and the country that had a good life reached a technology introduction agreement, imported a batch of hydraulic presses, introduced the advanced technology of hydraulic presses, and the factory also grabbed a 30NM die forging hydraulic press to assist production.

This hydraulic press belongs to the main engine three-beam four-column transmission type, the structure is relatively simple, but also used in the processing of large devices, rolling mills use it for some steel stamping that requires high precision.

Engineers like them, you have to quickly learn and understand the hydraulic press technology, can repair is basic, can improve the best!

Because the skill practice space with system space can be rented, He Yudong is now the first person to master the latest hydraulic press technology in the entire rolling mill!

Now, with several people, he is trying to improve the accuracy and pressure level of the hydraulic press at the lowest cost.

Although He Yudong can rely on the system to "penetrate the problem", directly confirm the direction of improvement, and obtain improvement drawings.

But the drawings have to be thoroughly eaten by himself, this is not enough, he also has to understand everyone else, all kinds of answers to problems, and when everyone understands, he can start practicing and confirm whether the improvement is successful.

Coupled with the pregnancy of the daughter-in-law and children at home, the black market has to be shipped regularly....

So, during this time, he was really busy.

If the time off work is relatively normal, He Yudong will go home to see his wife and children, get some good food for the whole family, and rest and relax; If he was busy in the middle of the night, He Yudong would not go back to toss, make do with staying in the courtyard house for a night, and then continue to be busy.

Therefore, no matter how Yu Li Yu Begonia was like a wolf and a tiger, he could only sigh when he couldn't even find his human shadow.

Finally, when the child in Ran Qiuye's belly was able to stretch out his little feet and kick him, the father who touched his mother's belly, He Yudong's research finally took a big step forward.

Because it is in the rapid development stage of the introduction of new technologies, all aspects, even some of the more senior leaders, attach great importance to this aspect of technology.

After all, now that everything is in ruins at home, and foreign countries are still technologically blocked, even if they buy machinery, it is difficult to buy, and they can often only buy some technical equipment eliminated from abroad.

For example, this time, Comrade He Yudong's breakthrough in hydraulic machinery technology, but the country did not agree to sell a part of the country after a good life!

When the director found He Yudong, the expression on his face was uncontrollable mixed feelings.

"Xiao He, the rolling mill probably can't keep you."

The director sighed.

"Technicians like you still have to get the R&D department to shine!"

He Yudong smiled modestly.

"I can do this, but I can't do without the support and promotion of the factory leaders, how can I think of leaving the rolling mill for development?"

"I am a brick of the motherland, where it is needed to move!"

The director of the plant sighed even more.

Jin Lin is a thing in the pool, and when it meets the storm, it turns into a dragon!

"Come with me, a leader wants to see you."

Riding in a car that was still quite rare in this year, He Yudong came to a small western-style building and met a very powerful figure even before he crossed over.

It is no exaggeration to say that seeing this leader, He Yudong's face was not showing, and his palms were full of sweat.

Although the leader lay dormant during this period, after this gust of wind passed, he was not an ordinary rise, and he was also admired in later generations.

Moreover, this old leader is a good leader who has a good beginning and a good end, and even is famous in history.

Before crossing, when he was closest to this leader, he had only seen a glance at some activities of He Yudong from a distance, but he did not expect that the parallel world after crossing could be so close.

...... Even shook hands!

He Yudong's heart couldn't stop jumping wildly.

The leader is very kind, speaks with a little local accent, and the person looks peaceful.

"The little comrade is young and very good."

“...... Thank you, thank you for the encouragement. He

Yudong rarely stumbled a little when he spoke.

"I heard less than you, he went to your rolling mill two years ago, and he was very impressed with you."

What he said was the leader who He Yudong had accompanied a table of banquets in the previous two years, and only this leader could call that person less.

"Did you mention that you carry a notebook with you?"

He Yudong is especially glad for his good habit of insisting on studying and carrying notebooks with him. He immediately took out his notebook from his arms and placed it on the table: "Please take a look." The

leader smiled.

"Comrade Xiao He, don't be so nervous, I'm not a tiger, I don't eat people, ah."

He Yudong smiled a little embarrassed.

He picked up He Yudong's notebook and looked at it carefully.

He is also knowledgeable, and as far as He Yudong shows it, he can see that the foundation is solid and he has his own ideas.

"Comrade Xiao He, with your potential, you can make greater contributions to the development of our heavy industry." The leader looked kind, "Come on, let's talk, do you have any new ideas?" Talking

about his major, He Yudong relaxed a lot.

He is glad that he has worked tirelessly over the years, studied hard, and learned a lot by relying on the system, surpassing the mechanical structure and technology of this era.

Before helpless to the fierce wind of the times, He Yudong was not good to come out, and he had no choice but to have the level of productivity and social development at this time, and some things were not easy to take.

Now there is this opportunity to face the leadership, not at this time, but when!

Chatting up, He Yudong had long forgotten his previous nervousness, and even directly asked the guards for drawing pencils and steel rulers, drew on the spot, and drew the mechanical sketches that he had been pondering for a long time.

"This is ... Side roll adjustment model? "

The leader saw the doorway.

"Yes! This is a sketch of a two-roll disc pipe rolling mill, and I'm still working on roll straightener technology. Since this is only my personal research in my spare time, it is not perfect, but according to some of the models I have made, there is room for implementation. "

The leader saw the rise of the rise, and directly sent someone to call an expert on machinery to come over and discuss together.

This expert's name is Hang Xingxue, and he also studied military industry on Lao Mao's side. Originally, it almost blew him off when the wind picked up, but the leader stepped forward to protect him, and now he is working at Gyeonggi Heavy Industries.

"Hey-if this technology can be established, then there will be a major breakthrough in the technical problems of producing large wedges, high precision, and high-strength variable panel materials in our aircraft manufacturing industry!"

Hang Xingxue's eyes lit up all of a sudden, he clutched the drawing tightly in one hand, and his gaze went back and forth between the leader and He Yudong: "Leader, you, you have discovered a genius!" "
