#222 - 10,000-ton hydraulic press is built!
The first phase of construction at the Saibei and Sanshan bases has been fully completed, and production is beginning to explode.
Along the rivers and mines in the deep mountains and forests, rows of indigenous blast furnaces and steel mills stand side by side, spewing out countless molten iron and steel every day, which are then transformed into various cylinders, gears, or cast parts for some kind of shell.
These are then gathered through simple roads of various sizes to the base's mechanical factory, where they are assembled into mechanical equipment, cars, or tanks.
If there were a large screen that could display the entire base's production, you would find that it couldn't display everything completely, because so many factories, large and small, have been built among the thousands of mountains and rivers of Jin.
In addition to the military industry series planned by Ren Zhong, there are also many local civilian factories that have sprung up on their own. Technologies such as steel and mechanical processing inevitably spill over, becoming part of the local civilian industry of the base.
The smoke-filled mountains have pushed Jin's PMI to enter the 21st century ahead of schedule, but Ren Zhong would rather bear this cost.
Dawn Heavy Machinery Research Group.
Ren Zhong looked at the behemoth in front of him and couldn't help but feel a surge of excitement.
A 10,000-ton hydraulic press!
To save costs and reduce energy consumption, Ren Zhong decided to first manufacture the historically successful 12,000-ton self-weight hydraulic press.
It is composed of 13 extra-large components, which include four columns, six working cylinders, and three crossbeams. From the design perspective, it seems to be a "huge body but simple structure" behemoth, but in reality, it is the opposite. Its structure is very complex, requiring the calculation of over ten thousand data points to ensure the correct direction of construction.
In the original manufacturing process, precise design drawings were a major obstacle, and the actual operation was even more daunting.
However, Ren Zhong took a shortcut in this space-time. Designing these was actually the easiest part – simple plagiarism. The design and manufacturing data of this 10,000-ton hydraulic press have been declassified, and he had the opportunity to obtain relatively complete data from the archives.
Manufacturing the columns and working cylinders was no longer a challenge for the border region.
The more difficult part was the three key crossbeams. The main construction material for these crossbeams was super-large steel castings, which could not be formed in one piece, so welding technology was needed to fuse the steel plates together.
Faced with giant castings, the current domestic electric arc welding technology could not complete such welding.
Electric arc welding can only weld some small and medium-sized steel castings and cannot complete the welding of super-large steel castings weighing hundreds of tons. Fortunately, Ren Zhong got the complete script and knew that electroslag welding technology could be used to weld such super-large steel castings.
Therefore, he obtained a complete set of electroslag welding technology for them. He also provided large gantry crane technology, allowing these huge castings to be quickly installed in place, which was much more advanced than using jacks to lift them little by little in the original space-time.
It also greatly reduced the workload and time. Even so, this super-large guy with more than 40,000 parts still became the equipment that Ren Zhong spent the longest time building in the Bright Sword era, taking nearly nine months!
Of course, compared to the 3-year construction cycle in historical space-time, this is already considered light speed.
Because Ren Zhong did not allow any stagnation in the research work, including the design work, which was directly applied in its entirety. This alone saved more than half a year, not to mention the manufacturing of parts. Tens of thousands of parts were distributed to the border region's mechanical processing plants to be produced with all their efforts.
This step alone saved at least another year or more, plus the direct introduction of electroslag welding technology in the installation phase, making the welding work of the largest castings even smoother.
This is how the construction of this behemoth was completed in just nine months.
"Mr. Ren, what do you think we should name this 10,000-ton hydraulic press?" Old Professor Chen Mingjie, who was extremely excited, looked at the hydraulic press as if he were looking at his own child.
As the first person in charge of the project team, although he had Ren Zhong's data guidance and basically did not take any detours, only he himself knew the joys and sorrows experienced in turning the things on the data into reality.
But such a huge achievement also made Chen Mingjie intoxicated.
"Let's call it Jiangnan!" Ren Zhong blurted out.
From Ren Zhong's name, the old professor tasted a hint of the revival of a great power.
Such a name will not disgrace this behemoth.
"Let's test the capabilities of this big guy," Ren Zhong watched for a while, but after all, he didn't have any intuitive feelings, so he simply let them do a practical test.
Connected here is the steel plant next door. In the future, there will also be an aluminum alloy processing plant next to it. The heated red-hot steel is quickly sent to the 10,000-ton hydraulic press through a conveyor belt. Ren Zhong watched as the steel castings, more than ten meters long and two or three meters high, were pressed into a rolling pin-like forging under the hydraulic press in the blink of an eye!
There was no trace of hardness at all. The 10,000-ton hydraulic press is indeed worthy of being a behemoth in modern industry! With this,
Although this hydraulic press is not ranked too high in the world today, the Third Reich has already developed stronger hydraulic presses.
But if it weren't for Ren Zhong's intrusion into space-time, this hydraulic press would not have been built until at least the 1960s, almost twenty years later than now!
Twenty years, for some industries, it's already a world of difference!
Now, there is nothing that can stop Ren Zhong from building large aircraft.
Whether it's the P51D or the C-47, Ren Zhong has completed the most crucial closed loop in terms of manufacturing tools.
In the month following Ren Zhong's attendance at the ribbon-cutting ceremony for the commissioning of the ten-thousand-ton hydraulic press, the first Border Region-made Mustang fighter was successfully assembled!
Wang Jianrong, the strongest pilot in the Border Region, hailing from Jianqiao in the KMT-controlled area, left a suicide note and resolutely boarded the Border Region-made Mustang fighter.
On the silver-white fuselage, still wet with 001 paint, a red star encased in the 'August 1st' emblem stood out strikingly.
This was Ren Zhong's insistence; this first fighter jet made Ren Zhong involuntarily bring some things from the main world.
Ren Zhong believed that this emblem was worthy of such a warplane.
The Blue Sky White Sun symbol was indeed unworthy!
However, among the people present, not a single one could understand Ren Zhong's feelings at this moment.
Including Staff Officer Ye, who considered himself the most understanding of Ren Zhong.
At this moment, he was also ecstatic, watching the first fighter jet made by themselves, cheering along with the surrounding workers, each with tears in their eyes.
Even though the first flight hadn't taken place yet.
The propeller started to spin, and the 001 fighter successfully started!
This was not a problem; everyone had tested it in the workshop, and all subsystems had undergone multiple individual checks and experiments.
Immediately afterward, the fighter began to taxi, accelerating...
The increasingly fast warplane, amidst everyone holding their breath, finally completed the short ground run of just over 300 meters, but in everyone's hearts, these few hundred meters felt like a century!
Takeoff!
Pulling up smoothly, Wang Jianrong, just like usual, used the most orthodox and conservative method to pull the control stick, holding his breath as he piloted the fighter away from the ground, only then resuming breathing, and then continuing to slowly ascend.
His eyes constantly scanned the data on each instrument panel.
“Command center, Dongdong Yao (001) altitude 340! All normal!” Wang Jianrong reported the first status information after takeoff.
Beside Ren Zhong, a signaler carrying a radio acted as the temporary command center.
“Dongdong Yao, please slowly ascend to 3000 meters and then return!” Seeing that the warplane's takeoff was normal, Ren Zhong issued a new order according to the test flight plan.
This was the first flight, mainly to verify takeoff and landing, to achieve a complete flight.
In fact, test flights in the real world are even more cumbersome; taxiing on the ground has to be done multiple times before a test flight is allowed.
But in this time and space, there isn't that much time. After the ground subsystem test run is normal, if the taxiing state is good, it can take off directly.
But that's all.
After verifying the complete driving process of the first takeoff, the next step is to conduct a comprehensive analysis of the warplane to see the impact on various parts of the airframe after flying into the sky, whether it meets the expected state, and whether there are any special losses.
In the sky, during the takeoff and landing process, there is a huge test for the airframe, landing gear, and tires.
“Command center, Dongdong Yao understands.” In the air, Wang Jianrong, who was becoming more and more proficient, had already relaxed and began to pilot the warplane to continue increasing altitude.
Soon, he flew to the altitude commanded by Ren Zhong, and then Wang Jianrong didn't mess around, flying steadily for a while before starting to turn the plane around and return.
When landing, although there was a little bump, it was harmless, and the warplane landed perfectly.
A large number of workers hadn't even waited for the warplane to come to a complete stop, and they all jumped up happily!
Even Ren Zhong, at this moment, was infected by the crowd and had tears in his eyes as well!
There was a kind of indescribable feeling like when he first saw the J-20 flying!
Although these two types of aircraft are separated by several generations, in this world, everyone's feelings are the same as in the 21st century in a different time and space.
This is an important and solid step for us to go out!
From today, we are no longer a guerrilla force with millet and rifles.
Tanks and fighter jets, we will have them all!
On land, unprecedented progress has been made.
Although warships are still out of reach for the time being.
But with today's things, sooner or later we will also have our own strength on the ocean.
Mass production of Mustang fighters means a dual breakthrough in the Merlin engine V-1650 and the ten-thousand-ton hydraulic press.
This means that in terms of casting and forging, the Border Region Dawn Research Institute has jumped to a new level and has the ability to produce most of the weapon systems in the world today.
Although the production capacity of warplanes is limited by the production volume of this hydraulic press, at most 5 can be mass-produced per month now.
After repeated test flights, the pilots did not find much difference between the Border Region-made product and the products far exceeding those of the Rogue Eagle. From a driving point of view, they could not feel it at all.
On the contrary, in terms of communication, the Border Region's communication subsystem is better and has a longer range than the original Rogue Eagle's.
In terms of weapon systems, after adopting the 20mm G20 aircraft cannon, the firepower is stronger than the original version.
Even if the firepower density is a little worse, the G20 not only shoots farther but also has greater power. Hitting the little devils' warplanes will create a big hole, and key parts can even be penetrated with one shot!
After Wang Jianrong and the others repeatedly evaluated and simulated confrontation, the new Border Region-made Mustang may not be weaker than the original Mustang in combat effectiveness, even if the configuration of 2 machine guns is reduced.
The Border Region Divine Eagle Brigade will start adding new partners every month from now on!
The students in the aviation class originally felt that it would be difficult for them to get a chance to get on the plane, but now they see that these warplanes are starting to be produced themselves, and they are soon worried that they will not be able to fly them all. I am afraid that one person will have to fly two!
After all, the current aviation class only has a scale of 50 people.
The second update, please recommend votes and monthly votes! (There is a slight problem with the previous chapter that is under review, you can see it tomorrow)
