Countercurrent 1982

Chapter 161 Sense of Superiority

Seeing the arrival of the factory leader, Wang Qiang, the workshop director, immediately greeted him with a smile on his face.

And the workers from the first workshop who were going to participate in the competition and the people from the seven or eight technical departments of the main factory also prepared the workpieces for their respective modified lathes, and all of them stood up straight.

Zhao Dongsheng glanced at Duan Yun but didn't speak. He still went around the desk with the other leaders.

"Director, there are currently 11 contestants who signed up to refit lathes. Shall we start the competition now?" The middle-aged woman who was behind Zhao Dongsheng and was in charge of recording asked Zhao Dongsheng.

"Let's start." Qin Gang nodded upon hearing this.

The next moment, the middle-aged woman called other contestants including Duan Yun together, briefly announced the rules and order of the competition, and announced the start of the competition.

Since the first workshop only arranged three new lathes for the modification competition this time, the eleven people were divided into four groups. It is not known whether it was intentional or unintentional. Duan Yun and Tian Feng were assigned to the last group for the competition.

The technicians from the three main factories who came up to the competition first still didn't touch oil. They just put the design drawings on the lathe, and then directed several workers in the maintenance team to help assemble the lathe.

Seeing this scene, Duan Yun couldn't help frowning. He didn't expect that what Wang Qiang said to himself just now was true. The factory uniforms on the technicians were spotless, and they stayed far away when they saw the workers working. Get a little oil on it.

Duan Yun feels that this kind of thing is somewhat unbelievable. In his opinion, it is not advisable for a real technical person to rely on some theories to build a car behind closed doors. Sometimes, such things as lathe modification must be done by yourself. , in order to know the fit of some modified components and the tightness of the installation, and those who study lathes dislike the greasy and dirty lathes and are unwilling to do it by themselves. Minor performance differences.

In fact, when Duan Yun was a technician in a locomotive factory in his previous life, there were also a few colleagues who didn't like to go to the workshop frequently to touch equipment. severely depreciated.

In the final analysis, this is a sense of superiority caused by class differences.

And when a few workers stepped forward to help assemble halfway through, Duan Yun finally realized that the three contestants in the first group had actually copied their own principle plan for modifying the old lathe, and even some parts were the same size as the old lathe. Duan Yun's old lathe is similar.

In fact, this is completely conceivable, because even though these technicians have a technical secondary school degree in related majors, their theoretical knowledge is much higher than that of ordinary employees, but they only master some mechanical principles and can understand drawings, but they are far from To achieve the attainment and creativity of being able to independently modify the lathe, copying and borrowing from Duan Yun's plan is the fastest shortcut!

But what made Duan Yun feel funny was that these people didn't have the slightest sense of shame for copying other people's plans, but they still had a bit of arrogance on their faces.

"Okay." Several maintenance workers stepped aside after assembling the machine.

"Start the machine." Seeing this, Qin Gang had started the machine.

"Buzz!"

After pressing the power start button, the main engine of the lathe started to rotate immediately.

The three machines in the first group not only copied Duan Yun's design, but even the processed components were still set as column heads, and they were rough lathes.

According to the processing procedures of the first workshop, the rough lathes are used for the old lathes in the workshop, and the new lathes are used for the fine lathes and the processing of the gear blanks, so their modification plan seems to Duan Yun , is simply a waste of functionality.

The test time is one hour. According to the rules, the lathe that processes the most parts in one hour wins.

Several leaders present also showed smiles on their faces when they saw the lathe started. In any case, this plagiarized modification has indeed improved production efficiency.

But in Duan Yun's view, it was wrong for the three people in the first group to copy their own designs, because the performance and structure of old lathes are different, and this kind of speculative modification will definitely cause problems.

Sure enough, after running for nearly half an hour, the three machines began to break down one after another.

"Crack!"

With a crisp sound, the turning tool of the lathe on the left shattered instantly, and metal debris almost flew out of the protective shell!
When Duan Yun refitted the old lathe, the feed rate was designed according to the speed of the main motor, but the power of the new lathe and the speed of the main machine were much faster. These technicians did not adjust the feed rate of the automatic feed at all, so it was too large It is inevitable that the cutting force and excessive cutting temperature will lead to the cracking of the blade.

"Crack! Kick!"

As the cutter heads of the other two machines also cracked, in desperation, several participating technicians hurriedly asked the workers beside them to replace the cutter heads.

"No need to change it." At this time, the chief engineer Chang Lin frowned and called out to the workers, his expression very ugly.

In fact, not only Cheng Changlin, but also several other leaders present and most of the onlookers can see that the modification of these three lathes has actually failed, and the design is obviously not reasonable enough, and replacing the cutter head is just a waste.

"Okay, the three of you can rest now." Factory manager Qin Gang waved his hand, motioning for the three to leave, and then said: "The next group begins!"

As soon as Qin Gang's words fell, the three people in the first group retreated to the side with a look of disappointment, while the three people in the second group began to step forward and direct the workers to assemble the lathe.

And when several workers started to help assemble the lathe again, the face of the on-site leader became a little ugly.

It turned out that the modification plan of the second group of participating technicians was almost the same as that of the first group. Some modified parts were almost the same size by visual inspection, so that the leaders of the factory who were not mechanically skilled could also see the tricks. It is obviously the result of people in a department 'learning from' each other!

Several veteran technicians in the crowd also smiled and shook their heads at this time. The atmosphere of the tense technical transformation competition suddenly became a little funny.

When Duan Yun, a small apprentice, finished refitting the old lathe and increased the production efficiency by [-] times, while allowing the factory leaders to taste the sweetness, it also gave many people the illusion that an apprentice like Duan Yun could successfully complete such a job. Excellent technical transformation, if professional technicians do this kind of thing, it should be very easy.

But today's situation has undoubtedly poured a bucket of cold water on these people, telling them the real situation is that there are very few people in the whole factory who are really capable of making excellent technical reforms, and the highly educated technicians in the technical department are almost None can beat...
