Countercurrent 1982

Chapter 687 Dream and Reality

"Manager Duan, the equipment in our factory is still a lot worse. Although the machine tool you modified is of a high level, it still can't meet the product standards of German automobile gearboxes. The gear accuracy alone is an order of magnitude worse. Could it be that the provincial department has just Can't you introduce a few imported CNC machine tools to us?" Kong Jing asked while walking in the workshop with Duan Yun.

"If we could directly purchase foreign advanced production line equipment, our country's auto industry would have been at another level." Duan Yun shook his head with a smile, and then said: "Don't talk about the world's top core technology equipment, even developed countries The commonly used high-precision CNC lathes are not sold to our country, and you can’t buy them if you have money. Didn’t your teacher tell you these things when you were in school?”

"I said something about the international technology blockade, but I didn't expect the blockade to be so strict." Kong Jing said with a sigh.

"There is no way around this, but our country was completely blocked by the West back then, and we still developed two bombs and one satellite, so the hardware facilities in the factory are currently lacking, and we have to find a way to solve it ourselves. You are all college students, yes Although our factory is a little small for the high-level talents trained by the country, we have the opportunity for you to display your talents. Once the Santana car gearbox technology is developed this time, it will not only bring benefits to our factory, but also bring benefits to our factory. China's auto industry has made great contributions, maybe you will become the pride of your alma mater and a role model for countless colleagues in the future." Duan Yun said with a smile.

Although Duan Yun generally likes to use material rewards to motivate the enthusiasm of subordinate employees, which is the same method used by private bosses in the future market to motivate employees, but in this era, there are still many people who value things like honor and can become the leader of the factory. Model workers and advanced workers are very glorious things, and everyone in the factory praises them.

"This is too difficult. When I was in school, I also had a lot of dreams. I feel that what I have learned is very powerful technology. If I leave school in the future, I will definitely be able to make some achievements. Now I come to our factory. , I found it really difficult to turn theory into practice, and after seeing the machines you modified, especially the automatic gear hobbing machine, it is simply a work of art. I never thought that someone would do this before You are really good at modifying a machine." Kong Jing lightly brushed her bangs on her forehead as she spoke, and turned her head to look at Duan Yun.

"In fact, no matter how strong a person is, what he can do is limited. You have just graduated from school and have not really been exposed to R&D work. There is always a process of adaptation. Your level itself is very high. If we If the R&D team can work together and form a tacit understanding, our factory will definitely become a business card of China's auto industry in the future..." Duan Yun said with a smile.

"Manager Duan!" At this time, Jia Zhiqiang and others who were recording data on the other side of the workshop waved to him immediately after seeing Duan Yun and Kong Jing approaching.

During this period of time, the 5 people in the R&D team were busy in the workshop every day. Apart from the high bonus and small bungalow promised by Duan Yun, they were also very strong people.

The college students in this era are also very rich. It is a remarkable thing to be able to enter the university campus from the thousands of troops. genuine talent.

Over the past few days, the five of them have already mastered the production process in the factory very comprehensively, including the machine modified by Duan Yun, and they all know the principle of it, and even hand-drawn the blueprint.

The only thing that confuses them is the chip technology used by Duan Yun in the circuit control of gear hobbing machines and carburizing furnaces. Since they are not majored in electronics, they are still at a loss as to the working principle of Duan Yun's use of chips to realize analog and digital control. water.

However, Duan Yun has always been secretive about these two core technologies. It is impossible for him to hand over such core technologies to a few college students who have just entered the factory. After all, Duan Yun has not yet established complete trust in them. If the core technology is transferred to other manufacturers in the same industry in the future, it will be equivalent to Duan Yun digging a hole for himself. Duan Yun will not let him happen.

Moreover, even if these college students do not understand the technology of electronic circuits, it does not matter, because their research and development group mainly develops automobile gearboxes, and mainly requires mechanical technology, and does not use the circuit part, so it will not affect The research and development work of these 5 people.

"What are you studying?" Duan Yun asked them after walking over.

"Manager Duan, what is this machine for?" Jia Zhiqiang asked Duan Yun, pointing to a machine next to the factory building.

"Um, this is a powerful shot blasting machine, which uses cast iron shot blasting. When our factory produces some key core components, this machine is occasionally used." Duan Yun saw that what Jia Zhiqiang pointed at was made by Cheng Qingyan. After the powerful sprayer finished, he smiled and explained.

The powerful shot blasting machine made by Cheng Qingyan is also a key equipment for processing Longteng's gearbox.

Duan Yun passed the test before, and the reverse gear of the first batch of Longteng gearbox samples that imitated the Lada gearbox was often damaged early during field tests in mountainous areas, mining areas, and forest areas. The root bending stress of the first reverse gear is moderately high, and the life test assessment situation is low. The reverse gear produced by the previous heat treatment technology has a large gap with the design requirements.

Later, Duan Yun improved the heat treatment process. After the first reverse gear was subjected to strong shot peening treatment, the fatigue test was carried out on the assembly bench. Under the torque equivalent to the engine output of 38kgm, the maximum life span was no more than 5 hours from the previous one. , increased to more than 25 hours, and the life span has been increased by more than 5 times.

This time, the Longteng gearbox won the national gold medal and obtained foreign trade orders. This powerful shot blasting machine also made a lot of contributions. Otherwise, the performance of the Longteng gearbox without strong shot blasting will be discounted. Received the National Gold Medal.

Usually, this powerful shot blasting machine is not turned on frequently, and it is usually only used twice a week. The reverse gear that needs to be powerful shot blasted is uniformly processed, so Jia Zhiqiang and the others have been in the factory for so many days, and they have not seen it yet. have used this machine before.

"It turns out that this is a powerful shot blasting machine." Jia Zhiqiang and others suddenly realized when they heard this.
