Countercurrent 1982

Chapter 676 Doubt
The worker in charge of loading puts the tooth embryos one by one neatly on the feed frame made of angle iron. With the slow rolling of the tool holder, the iron filings slide down quickly under the washing of the cooling oil. Grind a gear.

Jia Zhiqiang and others who watched this scene were surprised. Judging from the appearance, this gear hobbing machine is undoubtedly modified from a milling machine, but it is a bit bulkier than ordinary milling machines. It has an extra set of peripheral equipment and a circuit box, because It is wrapped in a shell, so you can't see the original inside, and you can't know how it works.

But this modified gear hobbing machine has high processing efficiency, stable performance and low noise, and its operation is even more fool-like. A young worker who looks young just presses a button, and spends the rest of the time handling raw materials and finished product.

"How is this possible..." Jia Zhiqiang racked his brains and couldn't figure out how this gear hobbing machine was modified. Realize automatic gear hobbing mode.

What is even more incomprehensible to Jia Zhiqiang and others is that the gear hobbing machine modified by Duan Yun can be adjusted through the control panel. In fact, it is possible to realize these adjustment functions, but there are many circuits and parts that need to be modified. At present, this automatic gear hobbing machine seems to have very few peripheral parts, which requires very high technology to realize. Even for college students like them, it is definitely not an easy task to achieve such a technical modification.

"Manager Duan, can you take apart the casing and let us see the internal situation of this machine?" Kong Jing turned to Duan Yun at this moment and asked.

"It's working hours now, and work can't be stopped. They have production quotas every day." Duan Yun shook his head lightly, and continued: "But it doesn't matter, I can show you the modification drawings of this gear hobbing machine later. , In addition, you also live in the office building at night anyway, and there are security guards on duty at the workshop at night. Let me tell them that you can take this machine apart at night and take a look, but you must ensure that it is before you go to work the next day. All restored."

"That's great." Jia Zhiqiang said after hearing the words.

Duan Yun's machine really aroused the great curiosity of these major students. After all, what they learned in school before was in textbooks, but the machine modified by Duan Yun is obviously not in textbooks. .

"Our factory is currently in this situation. We are short of manpower and can only rely on technological innovation to improve product quality and output. Now that you have joined us, I think our factory will develop better in the future." Duan Yun said to several people with a smile.

"You are very good. You designed and modified these machine tools yourself?" Kong Jing asked.

"Well, the main thing is that when I first came to the labor service company, the factory had been losing money for three consecutive years, and I was under a lot of pressure. At that time, I spent more than ten hours a day in the factory, barely producing these things. "Duan Yun pointed to the gear grinding machine and carburizing furnace on the other side of the workshop while speaking, and said to Jia Zhiqiang and the others: "The gear grinding machine and carburizing furnace over there are also modified, and these are all from our factory. Baby, it is because of these equipments that the Longteng automobile gearbox produced by our factory won the National Gold Medal and exported the products overseas, so in my opinion, although our country’s industrial strength is poor, as long as we can contribute our own With wisdom, one day you will achieve cornering overtaking.”

"That's really good!" Kong Jing said approvingly.

"Can you show us the gear grinding machine and carburizing furnace over there?" Jia Zhiqiang said to Duan Yun, staring at the gear grinding machine and carburizing furnace in front of him.

"Of course." Duan Yun smiled slightly when he heard the words, and then led a few people forward.

The next visit made Jia Zhiqiang and others feel even more incredible.

It is hard for them to imagine how a mechanical layman like Duan Yun could make so many successful equipment transformations, especially the transformation of carburizing furnaces. Even Jia Zhiqiang and the others don’t know much about this kind of equipment, including some machinery in Taiyuan. The factory does not use carburizing furnace equipment, and the labor service company, a factory-run group, can actually introduce this advanced equipment, and Duan Yun has also done digital transformation. In the eyes of these college students, even if they are college students It is estimated that there is no such a high level of professors who can modify such equipment.

For a whole morning, Duan Yun led the five of them to visit all the production equipment in the factory, and introduced the production process and various technical parameters of Longteng gearbox, and Duan Yun also talked about the future with them as the core The backbone set up a technology research and development team.

After get off work at noon, Duan Yun left the factory, while Jia Zhiqiang and the other five came to the cafeteria for lunch.

"Do you think the equipment in the factory was designed and modified by Duan Yun?" Sitting around the dining table, Guo Xiaoming asked his companion.

"I've seen his automatic lathe design in a magazine before. It's not a new technology. He just copied someone else's design and used it. It's nothing special." Liu Yijiang said disapprovingly.

"I don't think it's that simple. Even if the automatic lathe conversion plan can be found in a magazine, the conversion of the milling machine to the gear hobbing machine is really amazing. I still can't figure out how it works. It seems that we still underestimated him before." , He really should be a person who understands technology very well." Jia Zhiqiang said with some emotion.

If when they first entered the factory, these college students were still a little arrogant when they faced Duan Yun, then the arrogance has been reduced a lot now.

As mechanical majors, they can naturally see how difficult it is for Duan Yun to improve these equipments, especially the modification of gear hobbing machines and carburizing furnaces, which completely subverts their inherent cognition. His attainments in mechanical technology are beyond the reach of college students like them.

"I also feel that Manager Duan is not a simple person." Kong Jing also interjected at this time, only to hear her continue: "I don't know where he got the technology for modifying equipment, but from what he just explained Looking at it, he is definitely not a layman. He has his own unique insights and cognition in terms of machinery and equipment. Some things cannot be learned from textbooks. This person is really amazing."

"This is a bit interesting..." Jia Zhiqiang said thoughtfully.

"I think Manager Duan is very kind to us, the factory treats us well, and he also understands technology, and we can communicate with him easily in the future, so we should stay in this factory and do some practical things. Son, make a career out of it." Kong Jing said.
