Countercurrent 1982

Chapter 278

Cheng Changlin graduated from a mechanical major and has been engaged in technical work in the Red Star Gear Factory for more than ten years. Although his mechanical technology has not kept up with the changes of this era, he still has good attainments. The machine tools and equipment are well understood, and the technology is also very thorough.

In the last technical improvement competition of the whole factory, although the machine tool he helped Tian Feng lost to Duan Yun's modification plan in the end, the processing speed was indeed faster than Duan Yun's lathe, if he hadn't considered it in the design If the durability of the workpiece is considered, it may not be Duan Yun's turn to assign housing to model workers!
Hearing that Duan Yun was going to convert the milling machine into a gear hobbing machine, the first reaction in Cheng Changlin's mind was: Absolutely impossible!
You must know that milling machines and gear hobbing machines are completely different types of equipment. There may be common parts, but the processing principles are very different. If you really want to modify it, it will be very difficult, and you will almost have to change the entire machine design and layout. !

"Yes." Duan Yun nodded, and continued: "Most of the workpieces have been processed. Today I have been busy with a few masters in the maintenance team of the first workshop. The mechanical workpieces have basically been refitted. Tomorrow, To start adding motors and control circuits."

"You haven't told me about this, have you?" Cheng Changlin frowned and said, "In case the equipment in the factory is damaged..."

"I told Qingyan..." Duan Yun said.

"Ah, Duan Yun told me about modifying the milling machine, but I didn't expect him to..."

Duan Yun did tell Cheng Qingyan about this before, but Cheng Qingyan didn't take it seriously at the time, because in her opinion, such a big modification would take a long time to design and prepare, but what she didn't know was that Duan Yun Before the cloud entered the technical department, it already had a design plan.

"In addition, when I returned to the factory the day before yesterday, the factory manager talked to me. I also told him about the modification of the gear hobbing machine. He expressed that he would fully support me." Duan Yun added.

"Uh, that's it..." Cheng Changlin's face softened after hearing this.

Cheng Changlin could tell that Qin Gang had changed his attitude towards Duan Yun recently. Now that there were meetings in the factory, Qin Gang would always praise Duan Yun and encourage the young workers in the factory to pay respects to Duan Yun. cloud learning.

The 180-degree change in Qin Gang's attitude towards Duan Yun made Cheng Changlin feel a little unbelievable. He started his business with technology, and he was far less sensitive to political matters than Qin Gang and Zhao Dongsheng, so he never thought of the key points.

But no matter what, since the factory director had expressed his support for Duan Yun's modification, Cheng Changlin had nothing to say. After all, Qin Gang was the leader in the factory, and he had the right to let Duan Yun do this.

"I'm going to install the circuit tomorrow, and in about two or three days, I'll be able to pass the test." Duan Yun said.

"So fast!?" Cheng Changlin said in surprise.

In fact, Cheng Changlin didn't want to talk to Duan Yun, but when it came to technology, he talked a lot.

In his opinion, even if there is no problem with the technical solution, it is unbelievable that Duan Yun completed the modification of the gear hobbing machine in such a short time.

"If this modification can get some advice from you, Uncle Cheng..." Duan Yun said to Cheng Changlin in a sincere tone.

"Forget it." Cheng Changlin interrupted Duan Yun, and said disdainfully: "I'm not as capable as you!"

"Old Cheng, it's a good thing that Xiao Duan wants to carry out technological transformation in the factory. You can help him too. It's also very hard for Xiao Duan to pick up and drop off our daughter every day. Besides, you are also his leader. It will be good for you to help him." Yang Xiufang on the side persuaded her husband.

"You layman, don't interrupt!" Cheng Changlin's face flashed a look of displeasure, and said: "The milling machine is converted into a gear hobbing machine? What are you kidding! That is not a type of machine at all! How to change it? The previous automatic conversion of lathes was at least based on On the basis of the same processing principle, the milling machine and the gear hobbing machine have different working principles! There are also some technical things that you don’t understand after I tell you. Let me tell you, don’t do this kind of unreliable technical transformation! Waste of artificial materials and waste of machines are all state assets, and someone must be responsible for accidents! How can I follow such a stupid thing to do such a dangerous thing in the heat of my head!"

Cheng Changlin obviously thought that it was impossible for Duan Yun to modify the gear hobbing machine.

In his view, Duan Yun was completely dazzled by the success of the previous lathe technical transformation, and he wanted to come up with something bigger, so as to gain the attention and promotion of the factory. as a result of.

In fact, Cheng Changlin's guess was correct. Duan Yun's technical transformation this time did have a strong sense of utilitarianism, and he really wanted to rely on this project to get promoted, but what Cheng Changlin didn't expect was that Duan Yun's modification plan was completely mature and feasible. The reference is a technical article in the late 90s in China.

"Dad, it's not easy for Duan Yun, let alone he is your subordinate, if you call to help him, in case the modification is successful..." Cheng Qingyan on the side also persuaded.

"I'm doing it for his own good! He has just been promoted to be a technician, so he should accumulate experience at work, read more books, and practice more! The most feared thing for technical people is quick success! Think about it before the wings are hard. Fei, this kind of style will make him suffer a lot sooner or later!" Cheng Changlin glanced at Duan Yun, and then said: "If the milling machine really wants to be changed into a gear hobbing machine, it is impossible to change a few parts and get it done. Yes, it takes a long time to repeatedly conduct functional tests, and now he told me that the modification can be completed in two or three days, which is a big joke!"

"Old Cheng, what you said is too..." Yang Xiufang frowned slightly, obviously feeling that her husband's words were inappropriate.

"Uncle Cheng is right. It is really difficult to convert a milling machine into a gear hobbing machine with CNC functions. I also spent a lot of time designing the technical transformation plan..." Duan Yun was very calm, as if he didn't care at all. He cared about Cheng Changlin's attitude towards him.

"What did you say? You still want to convert it into a CNC gear hobbing machine!?" Cheng Changlin asked in surprise.

"Actually, it's not a real CNC gear hobbing machine, but it has some CNC functions. If conditions permit, I can further improve this machine..." Duan Yun said seriously.

"Do you know what a CNC gear hobbing machine is? We don't have many of them in the whole country! Just because you, a little technician, still want to make it, you really don't know the heights of heaven and earth!" Cheng Changlin was about to be overwhelmed by Duan Yun's arrogance Dazed with anger, he patted the table after a while and said to Duan Yun: "I will tell you here today, if you can really make this kind of gear hobbing machine with numerical control function, the position of the chief engineer will be in the future." I will give it to you!"
