Countercurrent 1982

Chapter 162
The second group almost repeated the mistakes of the previous group of three. The knives were all broken within half an hour after the machine was started.

These are all foreseeable things, after all, the two groups of people basically use the same plan.

In fact, this kind of accident can be found during the previous test, but the test time of these technicians is too short. After driving for more than ten minutes, they feel that the lathe is running normally, and they can't wait to decide that the modification is successful. If they If you take a little more time to test, you can definitely find this situation.

Seeing that the second group of participating technicians was terminated from the competition, Cheng Changlin felt a little embarrassed.

After all, Cheng Changlin was in charge of the technical department. It made him feel embarrassed to see that these technicians were seen through their underwear.

But the game is still going on.

In the third group of competitions, there was finally a lathe that persisted in running for an hour. Although the processing efficiency was not greatly improved, it was still a successful technical improvement plan, which also made Cheng Changlin regain some face.

Finally, Duan Yun and Tian Feng played in the last group.

As the only grassroots employee who participated in the lathe refitting competition, Duan Yun became the focus of attention from the very beginning.

As for Tian Feng, he seemed to be full of confidence today. After taking out the blueprints, he began to direct the workers to help him assemble the lathe.

But Duan Yun rolled up his sleeves and assembled it himself.

Duan Yun is the only contestant among the 11 who installs the workpiece by himself.

Duan Yun is very skilled and careful in assembling the workpieces. The gears are installed and fixed tightly, and then smeared with butter a little bit. Obviously, he loves the equipment very much.

Seeing Duan Yun's proficient assembly movements and focused expression, Cheng Qingyan, who had been standing beside her father, had a flash of surprise and admiration in her eyes. In her opinion, Duan Yun has skills, and his hands-on ability is not as good as before. It is really not easy to compare with fellow technicians and colleagues.

On the other hand, Tian Feng commanded several workers with a condescending look, with a bit of arrogance on his face.

After seeing this, the other factory leaders who were watching here were silent, but they all admired Duan Yun in their hearts. After all, there are not many people who are capable and know how to keep a low profile. Duan Yun has excellent qualities that many people do not have.

Although Duan Yun won the favor of everyone present, the ranking in the competition still depends on the operating efficiency of the machine.

After both sides finished assembling the workpieces, factory director Qin Gang signaled to start the machine.

"Buzz!"

The machine controlled by Duan Yun and Tian Feng started at the same time, and the main motor made a dull humming sound.

Factory director Qin Gang and chief engineer Chang Lin immediately looked at the lathe controlled by Tian Feng, while secretary Zhao Dongsheng focused his attention on Duan Yun.

Both of them are processing tooth blanks with a modulus of 1.5 commonly used in the factory, so this is a very fair competition between the two.

"prick!"

There was a sharp metal cutting sound, and the dark blue iron filings rolled down in circles, and a rough tooth embryo was quickly cut.

"Click!"

The lever pushes the horizontal turning tool forward, the processed tooth base part is cut off, the spring chuck is released, and the waste material also rolls down into the iron box under the spring chuck.

Duan Yun’s modification of the new lathe this time is similar to the principle of the old lathe modification last time, except that some transmission parts of the chassis have been redesigned, so that the linkage gears inside are more compatible with the current lathe power and speed.

But when Duan Yun turned his head and glanced at Tian Feng's modified lathe at the next station, he was stunned for a moment.

To Duan Yun's surprise, Tian Feng did not "copy homework" this time. Duan Yun saw at a glance that his automatic lathe modification plan was obviously different from his own. Two blades of different models were placed on the tool holder at the same time. There is also a linkage device next to it, so that this lathe can complete two automatic processing steps of rough turning and finishing turning at one time without manual replacement of the cutter head!

In fact, Duan Yun had thought of this plan before, but he finally gave up on this plan because the temperature of the workpiece was very high just after rough turning, and the finish turning without waiting for cooling would cause the workpiece temperature to be too high and deformed. Precision.

Moreover, the rotational speed required for rough turning and fine turning is also different. If the speed is automatically adjusted frequently, the gearbox needs to be re-improved, which will be quite complicated and potentially unstable. Therefore, after comprehensive consideration, Duan Yun still decided to rough The scheme that the turning and turning are processed separately.

Time passed by every minute and every second, and the atmosphere at the scene was a bit dull. Everyone's eyes were fixed on Duan Yun and Tian Feng's workstations.

Compared with the three teams that participated in the competition just now, Duan Yun and Tian Feng's design is obviously much more clever. In the eyes of many people, if nothing unexpected happens, the champion of this technical innovation competition should be decided by the two of them .

"Click!"

With a soft sound, the lathe at Tian Feng's station finished processing another tooth blank, which rolled down into the iron box below. Counting the twelve tooth blanks processed before, this modified lathe took half an hour Thirteen tooth embryos with a modulus of 1.5 have been processed in [-] minutes!
On the other hand, Duan Yun has just processed No. 11 tooth embryos, which is a difference of two finished products!
Seeing Director Qin's eyes, Cheng Changlin took the vernier card and measured the accuracy. After a while, he turned his head and smiled at Qin Gang, saying, "All passed!"

"Very good!" A smile appeared on Qin Gang's face when he heard this.

"Clap clap clap!"

Seeing this, the other onlookers of the factory leaders clapped their hands one after another.

Obviously, Tian Feng's modified lathe is more efficient, and it is basically a certainty that he won No.1 in this technical transformation competition!

For a while, there were endless praises for Tian Feng's technical level, and Qin Gang and Cheng Changlin also smiled when they saw this.

At this time, Cheng Qingyan, who had been observing the lathe for a long time, walked forward curiously, and picked up the blueprint that Tian Feng put on the tool cabinet just now.

The first time she saw this blueprint, Cheng Qingyan felt familiar, but when she saw the writing on the lower left corner of the blueprint, she suddenly turned her head to look at her father, and Liu Mei immediately frowned...

"Old Zhao, it seems that all the young workers in our factory are formidable young workers. Comrade Xiao Duan is indeed very good. Although he lost this time, if he can learn from his failures in the future, learn more and ask more questions, and lay a solid foundation in technology, he will have a solid foundation in technology in the future. I can still make a great contribution to the factory..." At this moment, Qin Gang turned his head and said to Zhao Dongsheng with a smile.

Although Qin Gang's words were very decent, in fact there was a hint of sarcasm.

"Wait a little longer, there are still a few raw materials that have not been processed." Zhao Dongsheng said with a slightly gloomy expression after glancing at Duan Yun and the lathe.

"I've been standing for a long time. Let's go to the control room to sit and drink some water and wait. I guess Tian Feng will finish processing in 10 to [-] minutes." When Cheng Changlin spoke, a flash of pride flashed in his eyes.

"Hmm..." Seeing that the other factory leaders had left after Qin Gang, Zhao Dongsheng frowned and looked at Li Duanyun again, then turned and left.

"Old Wu, help me watch the machine, I'm going to the toilet!" Seeing that the leader had already left, Tian Feng's face was full of complacency, he called a worker to help him watch the machine, left the station, and passed by Duan Yun At that time, the corners of his mouth curled up, and he seemed to be talking to himself: "Dog meat will not be on the stage after all..."

It's just that not long after Tian Feng left, a faint white smoke came out from the gap in the gear case of his machine...
