Super military empire

Now that the military channel is opened, people from the military will naturally operate it. Liu Yijiu is left idle. Anyway, this is a way for the military to release smoke bombs to the outside world.

The difference is that the military channel and the agricultural channel are merged.

This time Liu Yijiu wanted to do this, but instead of merging the military and agricultural channels, he created a military technology channel separately.

This channel promotes not only military-related matters, but also technological aspects.

Military technology, ordinary civilian technology.

There are not many TV channels in the Republic in this era, and there are also not many TV programs.As a later generation, Liu Yijiu has never been worried about not having enough programs. Moreover, in this era, TV programs are not broadcast 24 hours a day. A few hours a day is enough.

On the night before New Year's Day, Qi Hao and others arrived in Rongcheng. They will take a special train from Rongcheng to Deyang early in the morning of the next day and visit the trial production of a 70,000-ton large press there.

New Year's Day in 1987 is a day worth commemorating China's national defense cause and even the entire China.

The cold wind was still screaming. At six o'clock in Rongcheng, the sky hadn't lit up, and a fleet of convoys stopped in Rongcheng's not advanced railway station.

On the No. 1 platform of the railway station, there is a special train with only three carriages at the front. The number on the train is different from other trains and there is no line plate. It is also a green train, but the interior is very different.

As the person in charge of Duozhong, Jiang Wen arrived in Rongcheng on the first day, and he wanted to come here to personally meet many national leaders.

Along the way, Liu Yijiu was closing his eyes to rest his mind, while Jiang Wen was introducing their situation to Qi Hao and other leaders.

The special train has the preferential treatment of special trains, so there is no need to wait like other trains, especially from Rongcheng to Deyang, where there is only one station in between.It took just over an hour to reach Deyang from Rongcheng, and then directly along the transportation railway connecting Erzhong to the freight station inside Erzhong.

At this time, the Urals in China had just woke up from a deep sleep, and there were not many pedestrians on the street. In a few years, the breakfast stalls everywhere on the street were basically gone.

Those who go to day shifts are still preparing at home, and those who go to night shifts have not yet finished get off work.

Except for those who are used to getting to the workshop early, there are not many pedestrians on the road, but the second heavy is produced 24 hours a day. At this time, the night shift has not yet left, and the factory is still noisy. You can hear heavy machine tools before entering the workshop. The roar, the harsh friction sound of the tool when cutting large parts, and the roar of the forging machine with thousands of tons and tens of thousands of tons...

Enjoyed a hearty breakfast in the second canteen, and a group of people walked directly into the large press workshop.

It has been a long time, the workshop is lit up all night, and countless technicians are still making final preparations.

The large high-temperature furnace used for heating nearby makes the temperature in the entire workshop like a hot summer day.

Many technicians carried yellow helmets on their heads for the final inspection. Before Liu Yijiu and others entered the workshop, no one got a yellow helmet.

This time they entered the workshop no longer from the side passage, but directly from the front door.

Before they arrived, the huge rolling shutter door had been closed. As they arrived, they slowly drove upward, and the giant tens of meters high began to gradually appear in the sight of everyone.

"Heavy weapon of the country!" When he entered the workshop, he felt a rush of heat, and Qi Hao was about to stare out when he saw the big guy in front of him.

This one is much larger than the 30,000-ton die forging machine of Southwest Aluminum Plant!

"Chief, why don't you give me a calligraphy?" Jiang Wen has always been good at slapping his beards and horses. At this time, how can I let the leader leave calligraphy.

"Let's wait until the trial production is successful!" Qi Hao has never liked this tune, but at the moment in front of him, naturally he did not pour double cold water.

"As long as the inspection is completed, trial production can begin now! According to our plan, today will be produced for one day, and then shut down for inspection." Jiang Wen said immediately.

Now other workshops have started to work. Although it is the Gregorian New Year, many units have holidays. Erzhong is a smiling unit with heavy production tasks. Basically, each unit has no holidays. What's more, they are also studying. The experience of the Ninth Institute, working on such days, triple the salary.

It can also be used to change rest later.

"President Chu, you can introduce our country's heavy equipment to the chiefs!" Liu Yijiu saw that it was going to be cold, and he also hoped that the technicians would receive more attention than the managers and the chief engineer who designed this heavy equipment , How can I show my face, deepen the impression of the head above.

Chu Guorong glanced at Liu Yijiu gratefully. Even if he is not good at dealing with the chief, there is nothing to be nervous about under such circumstances.

If you are familiar, it will be much easier to get projects in the future.

After all, this 70,000-ton large press project belongs to the Ninth Academy, not the military or the country.

"The 70,000-ton large press project originated from the 65,000-ton large press that was used for the Yunshi project at the beginning..." When it came to technology, the young old man began to talk endlessly.

Even if he has seen it once, seen it countless times on the previous Internet, and even saw heavy equipment much larger than this one, Liu Yijiu is not as shocked as he is now.

After Chu Guorong finished the introduction, the temperature of the heating furnace next to it had reached and it was ready for forging.

"In total, the inspection of the various systems of the large press has been completed, and the preparations for trial production have been completed..." Cheng Xiaoci, the vice president, served as the deputy commander of the trial production.

The control system, hydraulic system, electromechanical system, mold accessory system and other inspections have been carried out time and time again.

And before that, the mold has been installed and debugged in place.

For large presses, the most troublesome thing is to install and remove molds, which are often tens or even hundreds of tons in weight.

"Start!" Chu Guorong didn't hesitate. After seeing the preparation work was completed, he gave the order.

After his order, the technicians on the control room operating platform on the left side of the big press started to take action. With the sound of "whoop", the traffic on the press started to move, and at the same time, it was originally closed. The moving parts of the large press also began to move upward in the sound of "boom boom", and the workshop that was still static instantly became noisy.

The huge mechanical monster has been activated. With the assistance of driving, the huge manipulator slowly picks up a blank shaped like "Y" from the high temperature box behind. Under high temperature heating and heat preservation, the whole blank emits orange light. There was another rush of heat in the originally steaming workshop, and immediately, the manipulator, under the careful operation of the technicians of the console, burned through, and it looked like the rough billet that was about to melt was sent to the worktable of the forging press several stories high. Move to the original position, and the manipulator next to the press starts to move, pushing the blank on the workbench to the position where the mold in the middle of the workbench is.

Under the operation of the technicians, the main girder, which was originally still and with the upper mold, began to slowly move downward under the huge hydraulic pressure changes.

"Boom, boom, boom", after a loud noise, the forging table closed, and countless sparks popped out from the gap in the mold intensively. It was really beautiful.

At this moment, everyone held their breath and stared at the forging table where the sparks were less and less. Not long after that, there was another roar. The upper and lower molds of the forging table opened slowly, one for the J-11 The large forgings of the landing gear appeared in front of everyone.

At this time, the original orange light dimmed.

The intense high temperature distorted the air above the workpiece.

"Wow..." When Liu Yijiu saw the situation, he clapped his hands first, and then the others who were still in a daze slapped them violently.

"Report, the first test of the 70,000-ton die forging press was successful!" Cheng Xiaoci, wearing a yellow work hat, reported loudly to the leaders. The smile on his face made his voice a little different.

Seeing the rough landing gear in front of him, Qi Hao said excitedly, "We have been engaged in the aviation industry for so many years, and have always said that we want to engage in large-scale aviation forgings, and today we finally realized this dream."

"Xiao Liu, didn't this thing fall heavily?" A leader who Liu Yijiu was not familiar with took Liu Yijiu and asked in a low voice.

Liu Yijiu glanced at him. If it was before, he would be sarcasm, but today, there is no at all, but patiently explained.

This is a die forging machine, not free forging. The main purpose of die forging is to close the mold by huge pressure, and let the blank inside change according to the shape of the mold.The shape of the blank itself is smaller than that of the mold, but the volume is larger than the mold cavity. Under huge pressure, the blank will change in the direction that the surrounding can change. In the end, under the constraints of the mold, only the internal crystal The granular structure becomes more precise, so as to achieve strength...

Free forging is the use of a heavy hammer to continuously beat the blank to make the blank into the desired shape.

Therefore, this thing will not produce too much vibration and loud noise.

"Hold up the flag with pride, and forge 70,000 hammers with passion!" Liu Yijiu murmured when he uttered a bold statement from the chief engineer of his 80,000-ton press in the world.

"Well said! The country's heavy weapon is like this. This is the hard work of countless national defense science and technology workers. Without pride and enthusiasm, it is impossible to have our big press in China!" Qi Hao faced Liu Yijiu Thumbs up.

The others applauded enthusiastically.
