Chapter 238, let’s get started

When Dong arrived, Engineer Shen looked at the drawings and asked Jiang Yan without listening, and Jiang Yan took the trouble to explain to him while looking at the drawings.

Jiang Yan called Master Sun over from time to time and explained to Engineer Shen the production of Yidong parts and the difficulty of repairing the parts.

During that back and forth, the two people actually communicated for almost half an hour, and there were quite a lot of issues behind the drawings.

Others were confused. Wang Tianlai and Zhang Xiang, who were listening to the exchange between Jiang Yan and Engineer Shen next to him, benefited a lot and once again updated their views on the installation drawings.

The conversation was almost complete when Jiang Yan and Engineer Shen said, "Engineer Shen, our private owners are discussing other matters. The most important thing now is whether the fine segmentation machine can be installed."

After hearing Jiang Yan's reminder, Engineer Shen, who was busy chatting, came back to his senses.

Will you come over tomorrow to learn how to install and repair the precision forging machine? I won't discuss the problem too much.

He said a little embarrassedly: "He came to help us, and by the way, he also learned something from Jiang Gong and me."

"Learn from each other, learn from each other."

After being humble, Jiang Yan began to instruct workers and engineers outside the workshop to install the precision segmenting machine.

The workers showed off their chants and carried the base of the lathe, which weighed hundreds of kilograms, under Jiang Yan's command. The bases were spliced ​​together like stacked blocks.

In less than half an hour, the machine tool base of the fine segmentation machine was completely spliced ​​together.

To connect Donglai, it is necessary to install other corresponding parts on it. The installation of those parts requires the most attention and precision, so Jiang Yan can do it himself.

Bearings: support the existence of the entire mechanical system and ensure its efficient and safe operation.

The bearing is an indispensable component in the mechanical system. It is an important guiding device used to support the mechanical device and coordinate its movement. Usually, the bearing has a load-bearing function, and its failure directly affects the safety of the transmission system. run.

The old shaft in the fine-segmenting machine had long been damaged, and the shaft produced by the lathe was not up to standard. After rough machining, Sun Deshui and his two apprentices carried out finishing machining.

Just to build a qualified axis like that, Sun Deshui and his two apprentices worked for three full days.

Its precision and polish are much higher than the previous surface-mounted shafts.

Behind Jiang Yan's command, two workers carried the shaft and installed it into the corresponding slot according to Jiang Yan's command.

After the installation was completed, Wang Tianlai quickly held a ruler in front to measure whether the installation position was correct and whether it deviated from the planned track.

After the measurement, Wang Tianlai gave everyone a thumbs up. Seeing Wang Tianlai's thumbs up, Jiang Yan breathed a sigh of relief.

The installation of the shaft is the most important step for this machine. If this step is wrong, everything will go wrong in the future.

Other parts were installed one after another at Jiang Yan's command center.

"Mr. Wang, turn the screw three turns and then back it out half a turn."

"Workers Shen and Zhang installed the screws according to the standards he said."

Seeing Wang Tianlai and the others tightening all the screws, Jiang Yan quickly spoke.

"Isn't it true that the tighter the better?" Wang Tianlai asked Jiang Yan in confusion.

When Wang Tianlai asked, the other two Wei Dai engineers also looked at Jiang Yan with puzzled faces.

Seeing their puzzled looks, Jiang Yan asked Engineer Hans about the intention of turning the screw back half a turn.

"Isn't that the reason? Hans Country is worthy of being a country that produces top-notch machine tools. It is indeed unique. Even installing a screw requires so much attention. Mr. Jiang, can you please tell me? They are very serious.

I don’t know, there are twists and turns in there.”

The reason why Hans Country can have so many top machine tool companies and produce the world's top machine tools is inseparable from their accumulation in the field of heavy industry.

It is also directly related to the early development of high-end machine tools by Hans. Hans began to develop machine tools around the 1880s. By 1969, its machine tool exports had occupied the first place in the world.

Hans Machine Tools not only developed earlier, but also has a layout in the entire machine tool industry's industrial chain. A large number of their foreign companies are directly or indirectly engaged in the machine tool industry, and a large amount of funds and manpower are invested in scientific research.

Therefore, Hans Machine Tools is not only a global leader, but also in the process of continuous development.

Even if Zhitong later had the ability to develop machine tools, it would still be inferior to Hans Country in the field of high-precision machine tools.

With the addition of various parts, the machine tool gradually became fuller, and the speed of the three people could not help but speed up.

Seeing that it was already noon, Jiang Yan and the others had no intention of stopping coming east.

Zhao Chang made a move to his secretary, who ran over.

"Xiao Sun, I'll go to the canteen and give them a meal." After he said that, he took out a few meal tickets from his pocket and handed them to him.

After seeing his secretary take the meal ticket, Zhao Chang turned to Guo Jianjun and said, "Xiao Guo, you are also going to help and bring all the food. He will see if it will be finished in a while."

After Guo Jianjun responded, he followed Secretary Sun out.

"Gong Jiang, what should we pack on the east side?"

Engineer Shen asked Jiang Yan with a somewhat excited tone.

As a technology geek, he was so happy. Not only did he see the detailed installation drawings of the precision segmenting machine, but he was also taught a lesson by Jiang Yanlegs. He felt that he was really good at that time.

Make a fortune.

There are only a few precision-section machines in the country, and I have been thinking about dismantling them for a long time. So I’m sorry for this cabin

When Jiang Yan heard Engineer Shen ask, he didn't say anything. He took the ruler and measured it again on the installed machine. The installation errors were all beyond his design.

"Worker Wang, prepare to install the screw rod." Wang Tianlai, who was standing where Jiang Yancuo was standing, gave the order directly.

After hearing Jiang Yandong's order, Wang Tianlai directly took the screw rod that had been prepared and placed it on the table.

The installation of the screw rod is a key place in the entire precision segmenting machine. It is related to the accuracy of the entire machine.

Although the screw has been tested accurately after manufacturing, it does not necessarily mean that there will be no problems whether it is installed after the part is installed.

To put it simply, no, although each part is outside the allowable error range calculated by himself, after all the parts are assembled, the allowable error will be further expanded.

In other words, the error tolerances of the two parts can be superimposed on each other or the tolerances can be increased. To a large extent, such tolerances will affect the overall performance of the machine, and even affect the life and accuracy of the machine.

Fortunately, all the newly produced parts were completed by Sun Deshui and his two apprentices. The parts they produced were better than the original parts.

Therefore, the worst thing Jiang Yan had calculated did not appear there.

Therefore, highly skilled workers play an irreplaceable role in repairing parts. Jiang Yan decided that he would only stay in the factory for one day, and then the repair parts must be handed over to Sun Deshui and others.
