Next chapter

Since the military channel has been opened, there are naturally people from the military to operate it, but Liu Yijiu is very idle, anyway, this is a way for the military to release smoke bombs to the outside world, and the military naturally does not spare no effort to carry it out. √∟

Unlike the original, 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 made a separate military science and technology channel.

This channel promotes not only military-related things, but also scientific and technological aspects.

Military technology, ordinary civilian technology.

In this era, there were not many Republic TV channels, and there were not many TV programs either. As a later generation, Liu Yijiu has never worried about the lack of programs, and in this era, TV programs are not broadcast 24 hours a day, and a few hours a day are enough.

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

New Year's Day in '87 is a day worthy of commemoration by the entire Chinese national defense undertaking and even the whole of China.

The cold wind was still howling, and at six o'clock in Rongcheng, the sky had not yet dawned, and a fleeting convoy stopped in the railway station in Rongcheng, which was not advanced.

On the No. 1 platform of the railway station, there is a special train with only three carriages in the front of the train, 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 the second group, Jiang Wen arrived in Rongcheng on the first day. He was going to come here to greet the many national leaders in person.

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

The special train has the preferential treatment of the special train. There is no need to wait like other trains, especially from Rongcheng to Deyang, where there is only one station in between. In just over an hour, it arrived at Deyang from Rongcheng, and then directly followed the transportation railway connecting Erzhong to the freight station inside Erzhong.

At this time, the Chinese Urals had just woken up from their slumber, and there were not many pedestrians on the streets. In a few years, the breakfast stalls that could be found everywhere on the streets were largely gone.

Those who work the day shift are still preparing at home, and those who work the night shift have not yet left work.

Except for those who are used to arriving in the workshop early. There weren't many pedestrians on the road, but the second was 24-hour production, and the night shift had not yet gotten off work at this time, and the factory was still noisy. Before you even enter the workshop, you can hear the roar of heavy machine tools. The harsh grinding sound of tools cutting large parts, and the roar of those forging machines with thousands of tons and tens of thousands of tons......

After enjoying a hearty breakfast in the double cafeteria, the group went directly to the big press workshop.

For a long time, the lights in this workshop have been bright all night, and countless technicians are still making final preparations.

The large high-temperature furnace used for heating next to it makes the temperature in the whole workshop feel like a hot summer day.

Many technicians wore yellow hard hats on their heads and carried out the final inspection, and no one in Liu Yijiu and others got a yellow hard hat before entering the workshop.

This time they entered the workshop and were no longer from the side of the personnel passage. Instead, you go straight through the main entrance.

Until they arrived, the massive roller shutter door had been closed. As they arrived, they slowly drove towards the top, and the giant mac dozens of meters high began to gradually appear in everyone's sight.

"The important weapon of the country!" When he entered the workshop, he felt a hot breath rushing to his face, and Qi Hao saw the big guy in front of him, and his eyes were about to pop out.

The one in front of me is much bigger than the 30,000-ton die forging machine of Southwest Aluminum Plant!

"Chief, do you want to give me a Mobao?" Jiang Wen has always been good at sneaking around and shooting horses, and at this time, he has to let the chief leave Mobao.

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

"As soon as the inspection is complete, we can start trial production now! According to our plan, we will produce for a day today, and then shut down for inspection. Jiang Wen said immediately.

Now other workshops have begun to work, although this is the Gregorian New Year, many units are on holiday, Erzhong as a smiling unit, the production task is heavy, each unit basically has no holiday, not to mention, they are also learning from the experience of the Ninth Academy, this kind of day to work, triple the salary.

It can also be used for later changes.

"Mr. Chu, you can introduce our country's important weapon to the chiefs!" Liu Yijiu saw that he was going to be cold, and he also hoped that the technical personnel would get more attention than the management personnel, and the chief engineer who designed this heavy equipment would have to show his face and deepen the impression of the chief above.

Chu Guorong glanced at Liu Yijiu gratefully, even if he was not good at dealing with the chief, in such a situation, there was nothing to be nervous about.

If you are familiar with your face, it will be much easier to make projects in the future.

After all, this 70,000-ton press project belongs to the Ninth Academy, not the military, nor the state.

"The 70,000-ton press project originated from the 65,000-ton press ...... that was used for the Yunshi project at the beginning" As soon as it came to technology, the young old man began to gush.

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

After Chu Guorong's introduction, the temperature of the heating furnace next to him has reached and it is 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, as the deputy general manager, 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 again and again.

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

For large presses, the most troublesome thing is to install and disassemble molds, which often weigh tens or even hundreds of tons.

"Let's go!" Chu Guorong did not hesitate, and after seeing that the preparations were completed, he gave an order.

After his order, the technicians on the operating table of the upper control room on the left side of the big press began to act, and with the sound of "woo", the car that was originally on the press began to move, and at the same time, the moving parts of the big press that were originally put together also began to move towards the top in the sound of "boom", and the workshop that was originally still static instantly became noisy.

The huge mechanical monster has been started, with the assistance of the car, the huge manipulator slowly clamps a blank similar to the shape of the word "Ya" from the high temperature box behind, under the high temperature heating and heat preservation, the whole blank exudes orange light, and the already steaming workshop is once again pounced on a hot gas, and then, the manipulator is burned through under the fine operation of the technician of the control platform, and the blank that looks like it is about to melt is sent to the workbench of the die forging press several stories high, and loosened and moved to the original position. The robot next to the press starts to move, pushing the blank on the top of the table to the position of the die in the middle of the table.

Under the operation of the technician, the main girder, which was originally stationary and carried the upper mold, began to slowly move downward under the huge change in hydraulic pressure.

"Boom, boom, boom", after a sound, the forging table closed, and countless sparks jumped out of the cracks in the mold densely, which was very beautiful.

At this time, everyone held their breath and stared intently at the forging workbench where there were fewer and fewer sparks, and after a while, there was another roar, and the upper and lower molds of the forging table slowly opened, and a large forging for the J-11 landing gear appeared in front of everyone's eyes.

At this time, the original orange light of the workpiece dimmed.

The intense heat distorted the air above the workpiece.

......Seeing this, Liu Yijiu took the lead in applauding, and then the other people who were still stunned also slapped them violently.

"Report, the first piece of the 70,000-ton die forging press was successfully tested!" Cheng Xiaoci, who was wearing a yellow work hat, reported loudly to the leaders, and the smile on his face made his voice change a little.

Qi Hao saw the landing gear blank in front of him, and said with some excitement, "We have been engaged in the aviation industry for so many years, and we 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?" There was a leader next to Liu Yijiu who was not very familiar with Liu Yijiu and asked Liu Yijiu in a low voice.

Liu Yijiu glanced at him, if it was before, he would be sarcastic, but today, he didn't have it at all, but patiently explained.

This is a die forging machine, not free forging, the main purpose of die forging is to rely on huge pressure to close the mold, so that the blank inside changes according to the shape of the mold. The shape of the blank itself is smaller than the mold, but the volume is larger than the mold cavity, under the huge pressure, the blank will change in the direction that can be changed around, and finally under the limitation of the mold, only the internal grain structure can become 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.

So, this thing doesn't make too much vibration and loud noise.

"Pride holds up the flag, and the blood casts a hammer of 70,000!" Liu Yijiu sounded the heroic words of the chief engineer of his world's 80,000-ton press, and muttered it.

"Well said! This is the important weapon of the country. This is the painstaking efforts of countless national defense science and technology workers, without pride, without blood, there is simply no way to have our China's big press! Qi Hao gave Liu Yijiu a thumbs up.

The rest of the crowd applauded enthusiastically.
