Chapter 390: The process of localization has accelerated
Although Liu Lang can rely on his brain's powerful computing and analysis ability to reverse the parameters of some machine tool parts, it is not easy to manufacture, but no matter how difficult it is, everyone has to do it.
Liu Lang's requirements are very high, that is, the parts on each machine tool are copied to me, in the process of finding problems to solve the problem, the steel is not up to the mark, let the professors of the School of Materials put forward a plan;
In short, regardless of whether the machine can be completely copied in the end, the technical aspects must be fully understood, and there can be no doubts.
If the manufacture of the stainless steel smelting furnace electric furnace is completed under the leadership of Xiong Huaizhi, then Andrews's machine tool imitation work has become Liu Lang's personal show, just he analyzed the parameters of many parts can make the speed of this work greatly advanced, even if the specific manufacturing is still completed by other teachers and students, but Liu Lang played a vital role is no doubt.
Everyone believes that perhaps half a year, at most a year, the most advanced industrial machine tools produced by the state will be born, and in this process, the first batch of high-quality industrial workers will also appear, compared with machine tools, these talents are what Liu Lang values the most.
Just when a group of teachers and students of Huaxia University were working in full swing in the laboratory, the manufacturing plants that purchased Andrews machine tools were also making continuous progress, and in May, the country's mass daily newspaper published a news that the fifth manufacturing plant in Liaobei Province took the lead in producing auto parts with an accuracy of 0.1 millimeter, reaching the world's advanced level, and the country's manufacturing level has been greatly improved.
The accuracy reaches 0.1 millimeter, which has barely met the requirements of some parts of Volkswagen, which can be said to mark a key step in the localization of Volkswagen.
Xiong Huaizhi deliberately read this report in front of everyone, but the people present only smiled slightly, and there was no emotion at all when the stainless steel smelting furnace was manufactured.
"Isn't it just to make car parts, what's there to brag about, if we're going to do this, I'm afraid we've already built most of the parts of that car by now!"
A graduate student pouted.
No one said that he was bragging, in fact, the German machine tool in theory, can manufacture most of the parts provided by Volkswagen for China, the reason why the domestic manufacturer took more than two months to manufacture the parts, is because the process is not good, this process refers to the manufacture of the parts themselves, and more importantly, refers to the manufacture of parts and molds.
Auto parts are very different from other industrial parts, and in order to manufacture them, you must first design a new mold.
The simplest mold is easy to make, for example, if you want to cast a rectangular or square large iron block, then use the iron plate to make an iron box in advance, and pour the red-hot molten iron directly into it to cool it and then complete it, this iron box is a mold.
However, there are more molds needed in the manufacture of parts, and each mold must assist the manufacturer's process to complete the work, so the manufacturing mold is also a very important part of industrial manufacturing, even no less than the machine tool itself.
There are too many basic processes, such as bending, reverse extrusion, cold extrusion, cold heading, embossing, blanking, bending, forming, drawing, expansion, hole turning, flanging, etc.
For example, to manufacture an ordinary tee pipe fitting, the commonly used mold is a kind of arc-shaped steel mold, and at the same time, a circular opening should be cut in the middle of the arc, and a red-hot steel pipe is pressed into the mold with a high-pressure machine, and the red-hot steel pipe will emerge from the circular opening, and then neatly cut at the emerging section, and a steel pipe will become a tee.
Tee pipe fitting mold is just the simplest one, the shape of many parts is strange, especially the parts on the car, the regular shape of the parts are not many, most of them are peculiar shape, the structure is very complex parts, to make molds for this shape of parts, it is definitely a job to test the brains of those designers.
Volkswagen has already had a complete set of molds for so many years of development, and these molds are all things at the bottom of the box, and they will definitely not be easily shown, so don't look at them to hand over the drawing parameters of the parts to China, but the molds have not come up with a set.
There is no mold, those designers of the country can only design by themselves, obviously the fifth manufacturing plant in Liaobei Province took the lead in making the mold, which is still a gratifying thing.
But in the eyes of the teachers and students of Huaxia University, is this worth celebrating? Look at a stack of drawings on the table not far away, which are all mold design patterns, of course, this is not a mold for automobile parts, but a mold for machine tool parts.
These mold drawings were completely drawn by Liu Lang alone, except for simple parts such as machine tool panels, all the slightly complex ones were designed, and each one was fine.
This can't be helped, the test of the design mold is a person's "brain hole", in fact, it is a person's imagination, Liu Lang's imagination still need to be said? It is the most complex parts on this machine tool, Liu Lang looked at it a few times and then designed the manufacturing mold, this mold is also extremely complex, so that many students can not understand the drawings, and they can only understand it under Xiong Huaizhi's detailed explanation.
It took a month or two to make a mold in Liaobei Province, but here, the mold is not a matter for them at all, and it is the "least valuable" process.
In addition, now the vision of these teachers and students of Huaxia University has been "high": we are manufacturing machine tools for production parts, and the rest of you are just using machine tools in the manufacturing realm, and the realm of the two sides is the same?
That's right, the use of machinery and manufacturing machinery are two different things, the use of anyone will, manufacturing is difficult, what Huaxia University is doing now is a major event related to the future of the country's industry, all the people involved have a strong sense of responsibility in their hearts, and at the same time are proud to be able to participate in it.
Liu Lang is very happy, just in the past two months Liaobei fifth manufacturing plant has successfully manufactured up to international standards of auto parts, this is a breakthrough, the mold seems complex, but many parts are similar, the first mold design success can master some rules, I believe that the mold of similar parts will be manufactured faster, then the process of automobile localization will be greatly accelerated, the previous life was in 92 years to complete the goal of eighty percent of the localization, I believe that this life will be greatly advanced, perhaps in the late eighties can be achieved。
