Seeing Zhao Guoyang's calm and calm appearance, Liang Hongjun was secretly surprised in his heart, but he was silent on the surface.
From the beginning to the present, Liang Hongjun has been shocked by Zhao Guoyang's various performances, and at this time he has somewhat adapted to his words and deeds.
Seeing that this young man did not have the slightest doubt after hearing the words "bent beam car", Liang Hongjun knew that the other party must know this new type of motorcycle.
A young man who studied mechanical manufacturing in college has such an understanding of the type of motorcycle, which shows that the other party must be a person who loves to learn, loves to study, and is knowledgeable.
In addition, Liang Hongjun noticed that Zhao Guoyang paid attention to the high-tech article on Huaxia Manufacturing, and the importance he attached to this young man in his heart far exceeded that of Ma Jian, the deputy factory director who came with him.
Wang Hongxi quickly took the frame diagram and put it on the table.
Looking at this neat base map drawn with a drawing pencil stroke by stroke, Zhao Guoyang secretly admired.
In the 90s, the use of computers was just beginning, and domestic enterprises were rare to see.
Although the two-dimensional design software AutoCAD came out as early as 1982, but because the domestic computer has not been popularized, Weiruan Doocad, the giant drawing software, at this time in the country almost no one knows, let alone applied.
During this period, most manufacturing companies used manual drawings when they produced drawings, and Siyang Group was no exception.
This frame drawing is very neat and exquisite, even with Zhao Guoyang's critical eye, he can't find any faults.
Of course, this drawing is only a general three-view view, which can only give a general idea of the outline of this frame.
If you want to actually prototype it, there are hundreds or even thousands of parts drawings missing.
Zhao Guoyang understands in his heart that only when the other party confirms that his Hongda Machinery Factory has this production capacity, will people further contact him and come up with more parts drawings.
"Comrade Xiao Zhao, this is the frame diagram of the C100 bent beam car that our Siyang Group is about to put into mass production, you can take a look, and by the way, give your opinions."
Wang Hongxi said with some pride.
This general drawing of the frame of the C100 bent beam car is a proud work designed by Wang Hongxi himself, led by more than 20 colleagues in the technical quality department, and took three months to design.
The level of its design is so high that even Liang Hongjun, the technical minister, is full of praise.
In Wang Hongxi's view, although this Zhao Guoyang is a college student from a serious class, after all, he has just graduated, and it is probably very good to be able to understand this complex professional drawing.
As for making comments, they are just kind words.
Unlike Wang Hongxi, Liang Hongjun is quite looking forward to Zhao Guoyang's reaction.
This young man has a maturity and stability that his peers do not have, and he can bring unexpected surprises in terms of technology.
Liang Hongjun has the idea of recruiting such a talent to his command.
Among the four people present, Ma Jian may be the most hesitant.
As the highest-ranking person in the negotiation of Hongda Machinery Factory, he certainly hopes to bring more orders to the factory.
But he himself is not proficient in technology, and he only knows a little about the frame drawings in his factory.
Now the frame diagram that the other party took out is far more complex than the first batch of frame drawings made for others in his own factory, and Ma Jian is a little blind.
At this time, his only hope was pinned on Zhao Guoyang. was surrounded by three people in the office, but Zhao Guoyang was not surprised.
After he took the drawing, he looked at it carefully for a while, and couldn't help but admire: "Minister Wang, your frame is a single-tube cradle structure, which is a big innovation in our domestic motorcycle industry." ” Hearing the words "single-tube cradle structure", Wang Hongxi's face was sluggish, and his mouth was even more open, looking incredible.
Liang Hongjun next to him was not much better, looking at Zhao Guoyang's gaze was like looking at an alien.
Ma Jian was the only one on the scene who couldn't understand, and when he saw the two ministers of the technical quality department of Siyang Group in a daze, he couldn't help but cautiously whispered to Zhao Guoyang: "Guoyang, what is this single-tube cradle structure?"
The leader asked, and of course Zhao Guoyang had to explain patiently: "Director Ma, this single-tube cradle structure is one of the three main structural types of motorcycle frames. ” "Generally speaking, a frame structure that consists of a single steel tube forming a cradle frame is called a single-tube cradle frame.
The other two types of construction are fork tube cradle frame and double tube cradle frame. ” "The difference between these three frames in use is mainly determined by the different structural forms of the engine.
In addition to the size and shape of the engine, it is also related to the position of the engine in the frame.
In the final analysis, the main reason for choosing a frame is to arrange the exhaust pipes and intake pipes of the engine more reasonably. ” "If the motorcycle uses a two-cylinder and four-cylinder engine, and the exhaust pipes are separated on both sides, then in general, a fork tube or single-tube frame will be used; If it is a three-cylinder engine, the exhaust pipes are placed in the middle and on both sides, and the double-pipe frame is mostly used; Single-cylinder engines, occasionally with double-tube or fork tube frames. ” Zhao Guoyang said while pointing to the cradle-like structure on the general drawing, and said to Ma Jian: "You see, Director Ma, this cradle frame not only has ideal strength and rigidity, but also has a beautiful shape and a sense of power, which is conducive to the structural layout of the finished car. ” "However, the production and manufacturing process of this frame has high technical requirements, and as far as I know, only island countries and some developed countries in Europe and the United States use this structure.
The frame structure of Siyang Group should be the first among our domestic motorcycle models, and it is a great technological innovation. ” Zhao Guoyang's explanation couldn't be clearer, not only Ma Jian nodded again and again, but Liang Hongjun and Wang Hongxi next to him stared at Zhao Guoyang for a moment, like looking at a monster.
After Zhao Guoyang finished speaking, Ma Jian suddenly realized.
He didn't notice the looks on the faces of Liang Hongjun and Wang Hongxi, but said flatteringly: "Minister Liang, Minister Wang, your factory is really amazing, it has opened a precedent for our domestic motorcycle manufacturing industry, I really admire and admire."
After Ma Jian's words were finished, Liang Hongjun and Wang Hongxi didn't react, and Ma Jian, who felt a little embarrassed, noticed that the two leaders of the Siyang Group were staring at Zhao Guoyang with wide eyes.
Ma Jian's heart trembled, and he was a little mistaken, thinking that Zhao Guoyang's explanation just now had something wrong.
He hurriedly explained: "This Minister Liang, Minister Wang, Guoyang is young, if you say anything wrong, you two will bear with me."
