Duan Yun and the three of them came to the newly approved 60 acres of industrial land.

At this time, the industrial land has been connected with the electronics factory with a fence, the engineering team worked overnight, and two brand new factories have been erected.

The 60 acres of industrial land were obtained by Duan Yun with a foreign exchange guarantee, and this land is of great significance to Duan Yun.

The new industrial land is divided behind the product technology research and development institute, and the electronics factory has been connected to a piece, but as a newly developed land, it is much quieter than some large electronics factories, compared to the lively dormitory building canteen and bathhouse building of the electronics factory, here this is more like the back garden of a large family, everything seems so deserted.

"See these two sets of newly built factories? Your main task in the recent period is to ensure that the two sets of factories are renovated into dust-free workshops. Duan Yun pointed to the two factories in front of him and said to Erhu.

The plug-in machine is a very demanding equipment for the environment, and the key components including the miniature cylinder, conveyor belt and ball bearing must operate in a dust-free environment, if any impurities fall into it, it will lead to the loss of the accuracy of the entire machine operation, or even damage to the shutdown.

In fact, Duan Yun wanted to hand over the decoration of the dust-free workshop to the army, but the electronics factory on the army's side was very busy, and the second tiger on the machinery factory was relatively idle, so Duan Yun handed over the matter of making the dust-free workshop to the second tiger.

"Dust-free workshop?" Hearing this, Erhu was stunned for a moment.

"That's right, the clean workshop is the workshop The environmental hygiene requirements are very high, and no dust and dirt can be brought in. Duan Yun paused, and then said: "At present, our country only has a dust-free workshop in the aerospace department, and it is only said that this kind of workshop needs to be equipped with a suspended ceiling, installed high-power air conditioners and ventilation fans, and the ground should also be painted. ”

In fact, Duan Yun had also visited some dust-free workshops in China in his previous life, but he only had a general understanding of its specific structure.

However, the dust-free workshop requirements for Duanyun to install the plug-in machine are not harsh, and there is no need to meet the same standard as the dust-free assembly workshop of the aviation department, so you only need to install a ceiling and air conditioning ventilation fan equipment, and then paint the ground, so that you can basically meet the environmental requirements of the plug-in machine.

"Master, I haven't seen a dust-free workshop before...... Erhu said with a sad face when he heard this.

"According to the plan I just proposed, the ceiling is installed, the air conditioning ventilation fan, the ground is painted, and you and the construction team will figure out how to decorate it, anyway, it must be much cleaner than the general workshop. Duan Yun said.

"Okay. Erhu nodded.

"I've got other things to do, and I'll leave it to you here. Duan Yun patted Erhu's shoulder, and then turned around with Peng Changming and came to the research institute.

In the office of the research institute, Duan Yun held a pen and paper and explained to Peng Changming the design principle of the plug-in machine.

The circuit part of the plug-in motor was made by the electronics factory, and the mechanical part of it was made by Duan Yun, which handed it over to Peng Changming.

“...... At present, the air pressure of this cylinder is 0.4~0.6MP a, and the air consumption is about 0.2 cubic meters / min, which requires strong sealing, no oil leakage, and high control accuracy......" Duan Yun drew a simple diagram of the mechanical part of the plug-in machine on the paper, and explained to Peng Changming.

"You came up with this part of the mechanical structure?" Peng Changming asked in surprise when he saw the simple structure diagram drawn by Duan Yun.

"The last time I went to Japan, I saw a plug-in machine from a Japanese manufacturer, and the interior was roughly like this. Duan Yun prevaricated casually.

"I see, I just say, to be able to come up with such a precise mechanical design scheme out of thin air, it is simply a fairy. Peng Changming showed a sudden expression, and then said: "Give me your sketch, and write the technical requirements, and I will redesign it for you...... It's kind of interesting......"

It was also the first time Peng Changming had come into contact with the plug-in machine, and this advanced equipment aroused his great interest, so much so that he was now a little eager to start working.

"The working principle of the plug-in machine is like this...... Duan Yun explained to Peng Changming the design principles of some plug-ins and key mechanical equipment, and also added a lot of details and technical requirements.

The performance of the plug-in machine that Duan Yun came into contact with in later generations must be far more advanced than the products of the early 80s, but this is mainly reflected in the digital control and sensing devices, and the principle of the mechanical part is basically the same as that of the products in the 80s, which are driven by motors, gear transmission and belt transmission, as well as cylinder and plug design, are also similar.

"Little Japan's design is really amazing......" After seeing Duan Yun explain the design principles and requirements of the plug-in machine in detail, Peng Changming said with emotion.

"Actually, our people are not bad, but they started a little late. Duan Yun smiled, and then said, "Then I will leave the design of the mechanical part of this plug-in motor to Professor Peng." ”

"Don't worry, I'll start designing now. Peng Changming carefully folded the simple diagram drawn by Duan Yun, put it in his pocket, and said to Duan Yun: "By the way, do we have overtime at night in the cafeteria?"

"There must be!" Duan Yun replied very dryly, and said: "From today onwards, I will ask the people in the cafeteria to bring you three meals a day plus supper, and what you want to eat, you just need to talk to the staff." ”

"That's great, I'll get busy first. When Peng Changming heard this, he got up and was about to leave.

"You can pay attention to your body, don't get tired ......" Seeing this, Duan Yun settled down.

"Got it. Peng Changming replied casually, and he had already walked out of the office.

There is a kind of happiness that can treat his hobby as a job, Peng Changming is like this, his obsession with mechanics is far beyond Duan Yun's imagination, even if he is over sixty years old and officially retired, this passion still has no cooling skills.

Duan Yun originally wanted to set a design deadline for Peng Changming, but now it seems that there is no need to propose a deadline at all, because Peng Changming will definitely do his best to work, and he doesn't need Duan Yun's pressure and spur at all.

Now that all the retired professors and technicians of the Product Technology R&D Institute have their own tasks, the next month or two will be a critical period for Duanyun Enterprise, and if all the projects of the Institute can be successfully completed on time, then his business plan will take a critical step......
