The principle of ultra forming diffusion bonding process is not complicated. It is nothing more than that two plates are sandwiched with a mesh metal core, the plate is sealed all around, and then placed on the abrasive tool. While using the pressure furnace to heat and pressurize, argon and other inert gases are input into the center of the cavity through the reserved conduit, so that the mesh structure inside will naturally expand under the action of inert gases, and then With the help of high temperature and high pressure firmly attached to the two sides of the plate, so as to form a hollow support structure.
The whole process seems very simple, just like blowing glassware, it can be made casually, but in fact, it is a virtue with other high-end manufacturing technology. The principle is always mastered by middle school students, but in practice, it can drive the academician level bigwigs crazy.
What is the high temperature and high pressure value of pressure furnace? How to control the processing time of parts inside? Do you want to apply insulation agent or flux before placing metal mesh on upper and lower plates? If so, what is the dose?
In addition, what about the specifications of metal mesh? How to deal with the plates on both sides? How to grasp the time when argon and other inert gases rush in
All of these are not solved by simple principles, but by countless experiments and accumulation.
Fortunately, at that time, Tengfei group already had jsnb-ii aviation and aerospace comprehensive analysis system.
You should know that this set of self-use system of Tengfei group is not the one that is shown to the outside world. Besides the comprehensive analysis ability of aviation and aerospace, it also has a very powerful calculation and analysis function for relevant process production and manufacturing equipment.
Combined with the application of simple vr virtual reality technology and computer pre tooling technology, combined with optimized algorithm, efficient software and large-scale computer, Tengfei group has made a very detailed research on the ultra new forming diffusion bonding process in a short time by relying on its own jsnb-ii system.
On this basis, combined with the problems encountered in the actual experimental verification and trial production, we constantly modified the data and algorithms in the software, and finally took out the structural components of No. 10 engineering verification machine, which is no less than carbon fiber with aramid fiber honeycomb structure, within the time specified by No. 10 chief engineer.
After testing, the weight of the structural components manufactured by the ultra forming diffusion bonding process is 8% heavier than that of the carbon fiber with aramid fiber honeycomb structure, but the structural strength is equivalent to that of the carbon fiber with aramid fiber honeycomb structure, and the corrosion resistance index is more than 12%.
What's more, five domestic enterprises have the corresponding production capacity for this kind of structural components made of all titanium alloy. After all, the core of the ultra forming diffusion bonding process is all kinds of micro operation data. As for the equipment, there is really no place to go up. The pressure furnace and inert gas have been available in China 20 years ago, as long as the data are refined Operation, if necessary, large-scale transformation is not difficult.
The chief engineer of No.10 project was very satisfied with the technological innovation of Tengfei group. After patting Zhuang Jianye on the shoulder, he almost took the remaining half of Erguotou to the roof and continued to curse his mother.
"Titanium alloy structural parts are very good, but aluminum alloy is the most widely used in No.10 project. You Tengfei group will work harder to see if this technology can be applied to aluminum alloy. I asked relevant personnel to calculate that if your technology can be widely used, the weight of No.10 project can be reduced by 6.7%. In this way, I can be sure of the combat capability of mass-produced aircraft It's more than 1200 kilometers. How about it? Try harder, young man
How's it going? Still working hard?
At that time, Zhuang Jianye wanted to say that Dashen, titanium alloy was already half dead. The second-hand Galaxy computer from the National Defense University of science and technology had burned the CPU for three times. It was not easy to stir it up. Would you please let us take off group mass production?
It seems to see Zhuang Jianye's mind. The 10th chief engineer glanced at Zhuang Jianye, who was just like the dead father-in-law. He laughed: "it's your business how to make it practical. I only see the result!"
With that, he patted Zhuang Jianye on the shoulder again and left with a group of people glowing red.
At that time, Zhuang Jianye wanted to stop the gray haired old man one by one. He held out his hands impolitely and asked for some money. As a result, the idea just came out and was cut off by Zhuang Jianye.
He asked chief engineer No. 10 for money? The chief engineer can turn around and stick out his feet to charge him for the patent fee.
Tengfei group has made great progress in aluminum lithium alloy and titanium alloy in recent years. Where did it come from? No.10 project supporting.
The flight control system is widely used in all models of Tengfei group. Where did it come from? No.10 project supporting.
The supporting technology of Tengfei group's aeroengine is becoming more and more exquisite. Why? It's the 10th project.
The data in jsnb - Ⅱ system of Tengfei group is detailed and stable. What happened? Most of them still benefit from the No. 10 project.
It can be said that by supporting the 10th project, Tengfei group has obtained unimaginable aviation supporting technologies, and these technologies are not ordinary general technologies, most of which are basic core technologies.
This is a country using a model to pull a comprehensive technology from point to area, but at that time the vast majority of domestic manufacturers did not have enough vision of marketization, and they did not know how to transform the available technology.However, Tengfei group, led by Zhuang Jianye, takes the first step in this respect, trying to transform the technology obtained from the 10th project into mature commercial products, so as to grab excess profits in the broad market.
Therefore, the success of Zhuang Jianye and Tengfei group is partly due to the development of self innovation, but it is more to stand on the shoulders of giants to have the conditions to impact the broader market.
In this case, if you ask for money from others, well, the chief engineer of No. 10 project doesn't mind sitting down to talk with you, and carefully calculate the account of No. 10 project technology of Tengfei group in recent years.
"The great God is the great God. I can't stir it up. I can't stir it up!"
Looking at the back of No. 10 project chief engineer, Zhuang Jianye is not only with emotion, but also with emotion.
Just when Zhuang Jianye thought about how to maximize the benefits of this new technology, the chief engineer of a new type of anti-ship missile came to him. Naturally, Zhuang Jianye couldn't let it go. He directly put out the super new forming diffusion bonding technology, which immediately shocked the other party.
No way, the weight of the inlet made by this super forming diffusion bonding process is 15% lighter than that of the traditional convex inlet, the structural strength is 39% higher, and the most important corrosion resistance is almost doubled.
So after some preliminary demonstration and test, an anti-ship missile research institute, together with the Navy, ordered 500 sets of titanium alloy inlets with bilateral inner pipes from Tengfei group, with a unit price of 400000 yuan.
Then, the wd-16p small turbojet engine and fuel tank form a complete powertrain, giving the other party a preferential price of 1.8 million yuan for packaging, and the total value of 500 sets is 900 million yuan.
With this money, Tengfei group has made persistent efforts to develop a new generation of Z-shaped wide chord hollow large-size fan blades on the basis of honeycomb hollow fan blades equipped with wd-52ml turbofan engine.
