Ding Wenjiang Dinggong sat in front of a 19-inch CRT monitor, uncomfortable. He looked down at the keyboard and mouse in front of him, and then at the vertical chassis under the table, full of absurdity in his heart.
It is also absurd that there are more than 20 students from Tianyangye Academy in front of Ding Gong. They are all metallurgical professionals. They are sitting in the newly built electronic classroom carefully moving the mouse in their hands, but they don't know what to do
The teachers and students are very confused.
The electric classroom is newly built, and the CAD course is also newly opened.
Dozens of computers in the classroom were picked up from the trash the day before yesterday. Many of the chassis are in tatters, nothing like high-end goods worth tens of thousands of dollars.
In the 1990s, the West had already used CAD software extensively in the industrial field, and Zhou Qingfeng directly used pirated versions. Even the teaching materials were purchased temporarily from HK.
Ignoring the copyright, Tianyang Printing Factory produced a hundred sets of photocopying plates in two days and sent them to the college. No textbooks have been translated, so I have to teach them all in English.
Ding Gong was the foundry engineer Xiao Jinlang accidentally encountered on the train.
The domestic scientific research field has long been in a state of'focusing on international advanced technology and striving to fill the domestic gap'.
This is what Ding Gong does. He focuses on the new technology of foreign foundry industry, and currently focuses on the application of computer CAD technology in the industrial field.
This 60-odd old man worked his entire life in a state-owned enterprise in Wuhan, and when he was about to retire, he gave up his job to his children.
For now, state-owned enterprises still allow their sons to inherit their father's business. A few years later, the state-owned enterprises went bankrupt on a large scale, and it was no longer possible to inherit their father's business.
In the 1990s, there was a word called "going hole", just like the traffic artists who went around doing business 30 years later. But now there is no agent in the'needing', who are able to run around in private.
Father Ding has retired, and he has been "walking around" in the past two years, mainly helping some local small factories to solve casting problems and earn some labor fees.
Casting has existed three thousand years ago, and it is the oldest manufacturing process of mankind. Those exquisite bronzes in ancient times were basically cast.
Compared with machining, casting is cheaper, faster, and larger, but the accuracy is lower.
The use of CAD technology in the field of mechanical manufacturing is a huge improvement. For example, when designing a mold, an intuitive three-dimensional structure is provided, and the drawing is quickly output, which greatly saves cost and time.
The West began to study CAD in the 1970s. With numerical control technology, this makes their industrial products more refined, high-quality, low-cost, and high-profit.
The outer casing of a gasoline engine with a displacement of 50 CC made by "Shengguang Machinery" is also cast. However, the precision of the mold is poor, and it needs to be processed many times on the machining.
But as long as the number of machining operations increases, this cost will not be reduced to a certain extent. Especially now that CNC machine tools are not popular, it is more expensive to rely on labor.
When Ding Gong said on the phone that he was studying the application of CAD in the casting field, Zhou Qingfeng was very happy. He immediately decided on a monthly salary of one thousand and gave the precious old man to Tianyang.
Father Ding was quite satisfied when he arrived in Tianyang. It was delicious and good to live in. It was much more comfortable than a small factory in an ordinary place.
He also ate some health care products distributed by the company. His years of migraine and old stomach problems have not occurred. He is even more energetic and his sleep quality has been greatly improved.
Life is good, but does this work
The technical strength of small factories in ordinary places is poor, and Mr. Ding will not talk about CAD when he goes there, mainly to help solve some mold problems of ordinary castings.
But Zhou Qingfeng has no shortage of people who do ordinary molds. He is very aware of the potential of computer technology. The backward industrial system will therefore be overthrown, greatly reducing product costs.
Since the 1990s, China's casting output has continuously exceeded 10 million tons. Two thousand years later, it surpassed the United States to become the number one in the world.
But you can't make a lot of money just by casting some iron knots. After domestic production is struggling, the problem of large but not strong is still inevitable.
Old man Ding did CAD in his original unit, but the effect was not high. The reason is simple. The domestic casting technology is backward, the quality of the employees is low, and the supporting equipment is vacant.
Even Ding Wenjiang has done CAD public relations several times for the purpose of writing papers and completing tasks arranged by some ministries and commissions.
After finishing it, everyone held a meeting, presented awards, and wrote a few summary reports. The results were put on the shelf and it was finished. As for the actual production, the outdated old technology is still used.
Unexpectedly, when he arrived in Tianyang, Zhou Qingfeng was here for real. The president wants to engage in large-scale computer-aided design and manufacturing, and also train a group of professionals.
Old man Ding has a big head, and he has never done this job.
But now that the money is taken and the food is eaten, I can only bite the bullet.
This is equivalent to doing all the mechanical processes from scratch. The original equipment and personnel cannot be used, which is very difficult.
Fortunately, Zhou Qingfeng is not a leader who only shouts slogans but does not give enough funds. He will not only approve research and development expenses of 50,000 yuan, which is just as terrible, but also urges researchers to save a little.
Zhou Qingfeng doesn't intervene in technology, but he understands what is the trend of technology. The dozens of 486s in this classroom alone gave Old Man Ding an unspeakable excitement and consternation.
It feels great to be rich!
Zhou Qingfeng will not send a group of middle- and high-school workers to do research and development for Mr. Ding. The students are all authentic college students. Although these students have no experience, they have strong learning ability!
CAD technology completely abandons manual drawing. Its essence is the combination of computer and machinery, designing an accurate digital model, and then making accurate parts accordingly.
This puts higher demands on the production line, production equipment, and production workers. Extensive management simply won't work, it requires large-scale technical investment and personnel training.
The key is that a lot of equipment can only be imported. Therefore, the state-owned factories can only complete some political projects to fill the gaps in the country, and there is no way to mass-produce them.
"It's amazing, it's amazing!"
When he touched the mouse in his hand, Old Man Ding laughed with joy. He visited abroad and saw factories in Japan and Germany.
Workers from abroad are all neatly dressed and work in bright and spacious offices. Domestic workers, Wu Qi Ma Hei, look like beggars.
Looking at the restless students in the classroom, the old man smiled and asked, "Why don't you seem to be very happy? Today's class has caught up with the trend of the times."
A student asked bitterly: "Teacher Ding, we learn this casting, will we be assigned to the factory as workers in the future?"
Oh..., the result is here.
The old man smiled and said: "If this kind of worker doesn't need to be exhausted, just sit in a beautiful office and work with a computer, and the monthly income can be seven or eight hundred, can't you do it?"
Hahaha..., a group of students laughed immediately.
Casting workers are all working at high temperatures, doing physical work, and the working environment is harsh, but they do not require high academic qualifications. The salary offered by the general factory for this kind of position simply cannot attract outstanding practitioners.
Father Ding knows the students' thinking very well. He grabbed the photocopy of the textbook in his hand. "The domestic mechanical drawing is still largely manual, but foreign countries have already begun to use computers.
I also don't have much experience to teach you. Now we can only rely on our own exploration to see how European and American countries do it
I know that the Institute of Metallurgical Engineering has begun to use computers instead of manual drawing, and the efficiency has increased significantly. This is a lifelong skill that can be used after learning.
You are luckier than me because I am old. I only have past experience, and you will have the future
As long as'Holy Light' can continuously invest in this industry, the right to speak in this industry in China in the future is likely to be in the hands of a few of you.
Work hard, students. The future can be expected! "
