Countercurrent 1982

Chapter 181 Denial
Duan Yun really likes this kind of sidecar motorcycle. When he was a child, when he saw someone riding on the street, he would always be envious.

Before the 80s, this kind of three-wheeled sidecar motorcycle was only equipped with military and police units, and only genuine army signal soldiers and police stations could use it. It was a copy of the BMW military motorcycle that smashed pumpkins in the movie "Escape from the Tiger's Mouth". sold by ordinary citizens.

It was not until the early 80s that the country released the civilian sales of this kind of sidecar motorcycles, but the number was very small, even in such large cities, it was basically not seen.

After the release of sidecar motorcycles for civilian use, some obsolete motorcycles that could only be used as scrap metal in the military and police forces had the opportunity to "use their waste heat". car.

But in general, this kind of sidecar motorcycle is more fuel-intensive, and the maintenance is relatively troublesome, so in the mid-90s, it gradually disappeared on the street.

The reason why Duan Yun bought two motorcycles in one go this time is that besides liking the domineering shape of this motorcycle, the most important thing is that he wants to buy it for a big use.

Now Duan Yun has many antenna sales outlets in the surrounding industrial and mining factories, but the meat factory and the 3528 chemical factory that are the farthest away need more than an hour to ride a bicycle. The physical strength of the workers is no small test.

In addition, if there will be a lot of installation business in the future, how to bring so many antennas to the installation of more than a dozen or more antennas a day will be a big problem. It can reach hundreds of kilograms, and it is indeed very hard to ride such a long distance with so many things.

With the sidecar motorcycle, things will become much easier and save trouble and effort. Although it is a bit expensive, the money saved in the time saved is enough to cover the consumption of gas money, so no matter how the business is calculated , are cost-effective.

Duan Yun's only worry is that he still doesn't know the depreciation degree of this second-hand car, but with Duan Yun's knowledge of machinery, he can completely repair it by himself.

However, Duan Yun still doesn't know if the flared pants can help him get this kind of second-hand pants, and there will be no news until the weekend.

……

On the night shift at night, Duan Yun did not go directly to the control room to sleep as usual, but continued to study the plan of converting the milling machine to the gear hobbing machine in the workshop.

Zhao Dongsheng reminded him in his conversation with him a few days ago that if he wants to take a higher position in the factory in the future, he must have important technical transformation technology.

In fact, Zhao Dongsheng didn't need to say it, Duan Yun was well aware of this, so he started to study the technology of converting milling machines to gear hobbing machines a long time ago.

If this technological transformation can be successful, it will undoubtedly be a very important matter for Hongxing Gear Factory. Not only can the processing efficiency of gears be greatly improved, but more importantly, the processing accuracy of gears can be improved at the same time, so that the factory's current production The precision of the six-level and seven-level agricultural gear products has been upgraded to the machining accuracy of the five-level automobile engine gear. This is definitely an epoch-making progress for Hongxing Gear Factory.

Although in his previous life, Duan Yun had seen domestic precedents of modifying gear hobbing machines with milling machines in the 90s, and had roughly understood the modification ideas in this regard, but in fact, due to the many differences in structure between milling machines and gear hobbing machines, this technology The difficulty of modification is still very high. Compared with the automatic modification of lathes, the difficulty is more than one step higher.

In fact, Duan Yun can now make a simple copycat gear hobbing machine.

The principle of this so-called copycat simple version of the modified gear hobbing machine is actually to use the x-axis of the milling machine itself to drive the universal indexing head to rotate automatically, so that the work of the rotating indexing head that should be done by the operator is automatically completed by the machine. , In this way, the entire gear milling operation is fully mechanized, and the efficiency is naturally improved.

However, although this simple modification can improve the efficiency of gear processing, in fact, the efficiency of the improvement is very limited, and it cannot improve the machining accuracy. Such a simple and inefficient technical modification is actually meaningless to Duan Yun.

Duan Yun’s milling machine modification gear hobbing machine not only needs to greatly improve the processing efficiency of gears, but also improves the processing accuracy of gears, and also has the ability to process complex gears. Only such modification technology can be called truly successful. Technical transformation, and only such a modification plan can become Duan Yun's trump card in the future, and it will be the biggest capital for him to gain a foothold in the factory in the future!
Duan Yun set a very high goal for this technological transformation, and correspondingly, the difficulty of completing this technological transformation is also very high. So far, Duan Yun has not completely completed this technological transformation plan, but fortunately he has With enough time to study slowly, he can make this technical transformation plan very detailed and perfect.

Since Duan Yun is not a professional technician, he cannot obtain the drawings and materials of the equipment, so he can only measure the size of the equipment workpiece by himself, and then record and draw it out by hand.

"Busy?" Just as Duan Yun was recording the workpiece data that had just been measured, a voice came from behind.

"It turned out to be Squad Leader Huang." Duan Yun turned his head and saw that it was Huang Haitao, and asked with a smile, "What's the matter?"

"Let's talk at the door." Huang Haitao pointed to the door of the workshop.

Afterwards, Duan Yun put away his pen and notebook, got up and followed Huang Haitao to the door of the workshop.

"What's the matter?" After leaving the workshop, Duan Yun took out a cigarette and handed it to Huang Haitao and asked.

"I heard something about you today..." Huang Haitao lit a cigarette, took a puff and said, "The factory meeting was held yesterday morning, and the secretary proposed to transfer you to the technical department..."

"Uh." Duan Yun was taken aback when he heard the words. Although he knew that the secretary would help him solve the work on behalf of the workers, he was still a little excited.

"Unfortunately, this matter was vetoed by Director Qin and Chief Engineer Cheng, who said that although you are somewhat technical, your education level is too low, and you have not even attended high school, so you are not eligible to enter the technical department..." Huang Haitao sighed Said in a tone.

"Yeah." Duan Yun frowned upon hearing this, but was soon relieved.

In fact, he had expected such a result a long time ago. Although he has successfully completed two technical transformation plans before, whether it is his contribution to the factory or his technical level, it is obvious to all, but his education has always been a flaw. , especially under the system of state-owned enterprises, as long as the factory director Qin Gang insists on taking his academic qualifications, the other leaders of the factory will have nothing to say. A factory with low educational background, even with skills and contributions, it is still very difficult to become a cadre.
