Song Qingshan, who had finished his meal, walked back to the workshop.
There weren't many people in the workshop.
Most of the rest were packing their things and preparing to go home to rest.
Song Qingshan carefully sized up the old rolling mill that he had just operated.
After personally doing it, he had already discovered some big problems, but he did not say them out loud.
During the normal production process of the four-high plate mill, the rolls were not allowed to produce non-technological axis movement.
However, due to the existence of various factors, the roll's movement was inevitable.
Even though the four-high plate mill was equipped with an axial-fixing device, the four-high plate mill was not equipped with an axial-fixing device.
However, when the axial-direction force exceeds the binding force, the axial-direction fixing device of the roll will be destroyed, causing the roll to move in the axial-direction, thus destroying the normal roll system.
In severe cases, it could cause secondary accidents and cause huge economic losses.
Therefore, it is necessary to find out the reason for the roll movement and find out the preventive measures.
The four-roll rhinoceros plate roller's axis movement was found in the actual measurement.
During the rolling process of a four-high plate mill, the resistance of the rolled piece was transferred to the backup rolls through the work rolls.
The axial-direction force is transmitted to the work roll through the friction between the rolled piece and the work roll.
Thinking of this, some ideas gradually formed in his mind.
He found a pen and paper and began to write and draw.
Yes, he planned to give this antique a technical modification and strengthen the safety protection device at the same time.
In Song Qingshan's opinion, it was actually not that difficult to comprehend this thing completely.
If it was just processing some medium-thick plates.
Although there were only three stages to produce a satisfactory plate, it was still not enough.
In fact, the requirements of the present and the future were different.
In his opinion, the craftsmanship was much worse.
He could completely change the operation method with some simple devices.
By automating the first two processes, the work would become simpler and more efficient.
After all, rolling steel was really physical work.
Even if his secret space could relieve his fatigue, as a lazy person, he could do it with a flick of his finger. Why not?
In fact, a few years ago, some people started to modify the technology, but it was still used on a small scale until the 1970s.
The reason why there was no large-scale promotion was that the standards of designers in the country were not uniform, and there was no place for them to study.
Generally, the efficiency of a poor technical modification would be even worse, and the processing of the object would not be comprehensive. After modifying one, one would have to modify another machine tool.
There were also some who had been slacking off as long as they did not make any mistakes and did not think about these things.
Of course, there would definitely be big names, but they would not come and get these small things.
They were all developing in the direction of rockets and aircraft carriers.
Although he had already read the clear internal structure of this old antique in the book.
But without seeing it with his own eyes, Song Qingshan was still a little worried.
Although this old antique was a rolling mill from almost twenty years ago.
It had been used for many years before it was introduced.
And it was a rolling mill that was about to be scrapped.
However, once the assets in the factory were irreparably damaged, it would not be a joke.
Even though he was a PhD in mechanics in his previous life, he still had to be extremely careful.
He studied it repeatedly, thought about it, and verified it carefully.
Even if he had 90% confidence, he would not rashly modify it.
He had to make sure that nothing went wrong before he could make a move.
Song Qingshan dilly-dallied in the workshop until he was the only one left.
He picked up the wrench and approached Old Antique.
It took a lot of effort to unscrew the outer shell of the four-high plate mill.
Inside were all kinds of black gears covered in engine oil.
He compared it with the style in his memory.
As expected, there were still some details that were different.
Song Qingshan lay on the ground, holding a pencil and roughly drawing the complete set of transmission gears. In the mechanical industry, drawing was the most basic.
Then, he compared it to the memories in his mind and highlighted the different details.
There were also places that had been used for too long and were worn out.
From time to time, he would lie on the ground and draw.
From time to time, he would stand up and measure some data with a calliper.
After busying himself for a while.
Song Qingshan looked up with sweat all over his face and looked at the clock hanging on the wall. At this time, the position of the needle had already shown that it was a little late.
There would be people from the security department coming to patrol later.
Thinking of this, he quickly repaired the outer shell that he had dismantled.
He got up, wiped his sweat, and put the notebook into the secret realm.
There were still a few parts of the steel plate that had not been removed. It seemed that he could only take it slow and remove one piece a day.
However, compared to before, Song Qingshan's thoughts were more complete.
He already had a general direction for the technical transformation.
The safety devices and some gear size had to be re-designed.
The next step was to draw a new set of blueprints, then take apart the outer shell and compare it. After careful study, he could start the technical modification.
After cleaning up, Song Qingshan was covered in oil, but he walked out of the workshop full of energy.
When she left the factory, she met the security team members.
Song Qingshan couldn't help but have a strange thought.
"Why is this like an underground special agent meeting?”
"But I'm doing a good deed, aren't I?" What the f * ck is this!”
......
"I'm a little hungry after all that. No, I have to eat something good.”
On the way home from work.
Song Qingshan, who was getting hungrier as he walked, looked left and right before turning into a dark alley.
With a thought, he instantly disappeared from where he was and entered the mystic realm.
It was still the same sunny day.
Rows of tall ears of corn swayed in the wind.
The lush leaves of the peanuts also danced on the ground.
Smelling the fresh air, his fatigue was instantly gone, and his entire body was filled with energy.
It was as if breathing the air in this space would slowly improve one's physical fitness.
Song Qingshan felt that there must be a bigger secret in this space waiting for him to discover.
However, now was not the time to investigate this. Song Qingshan did not forget his goal of entering.
He turned around and came to the chicken coop. At this time, the chick had already grown into a very fragrant appearance.
He wasn't surprised by this unimaginable growth rate.
He had already found out about it through the internal vision space in the morning.
"Slaughter. Divide into small pieces."
"Peanut!"
With a thought, an unlucky rooster flew into the air.
He let out a panicked cackle.
An invisible force was like a butcher dismembering a cow, and it was cleaned up in just two moves.
The leaf wrapped it up and delivered it to Song Qingshan.
The peanuts flew out of the soil automatically, and the roots were broken one by one. They were also woven into bamboo baskets by leaves.
"Awesome!"
When he saw it again, he still couldn't help but marvel at this magical scene.
After observing his surroundings, Song Qingshan left the mystic realm space.
Carrying the small cloth bag, he carried the chicken and peanuts to Nanluogu Alley.
