Siheyuan starts from a good life

In the following time, 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 also called Master Sun over from time to time to explain to Engineer Shen the production of parts and the difficulty of repairing them.

During this back and forth, the two people actually communicated for almost half an hour, and there were quite a few problems with the drawing.

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

When the conversation was almost over, Jiang Yan said to Engineer Shen, "Engineer Shen, we are discussing other matters privately. The most important thing now is to install this fine segment machine."

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

Today I came here to learn how to install and repair a precision forging machine, so I didn’t want to discuss the issue too much.

He said a little embarrassedly: "I'm here to help you, and by the way, I'll also learn from you, Gong Jiang."

“Learn from each other, learn from each other.”

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

The workers shouted slogans 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.

Next, it is necessary to install other corresponding parts on it. The installation of these parts is the most important and delicate, and can only be done by Jiang Yan himself.

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

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. Normally, bearings have a load-bearing role, and their failure directly affects the safe operation of the transmission system.

The old shaft in this 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 this, Sun Deshui and his two apprentices worked for three full days.

Its precision and polishing degree are much higher than the shafts installed before.

Under 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 stepped forward with a ruler 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 of this machine. If this step is wrong, basically everything will go wrong later.

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

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

"Workers Shen and Zhang installed the screws according to the standards I mentioned."

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

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

When Wang Tianlai asked, the other two 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.

"It turns out that this is the reason. This country of Hans is worthy of being a country that can produce top-notch machine tools. It is indeed unique. Even installing a screw requires so much attention. Jiang Gong, if you don't tell us, we really won't. You know, there are twists and turns here.”

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 Hansi State's earlier research and development of high-end machine tools. Hansi State began to develop machine tools around the 19s. By 80, its machine tool exports had ranked first in the world.

Hans Machine Tools not only developed earlier, but also has a layout for the entire machine tool industry chain. A large number of domestic 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, Hanse Machine Tools is not only leading the world, but also continuing to develop.

Even if the later generations of Huazhong had the ability to develop machine tools, they 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.

Zhao Changche waved to his secretary, who ran over.

"Xiao Sun, go to the canteen and give them a meal." After he said this, 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. Bring all the food. I'll see if it will be finished in a while."

After Guo Jianjun responded, he followed Secretary Sun out.

"Gong Jiang, what should we install next?"

Engineer Shen asked Jiang Yan with a somewhat excited tone.

As a technology geek, he was so happy today. Not only did he see the detailed installation drawings of this precision segmenting machine, but he was also taught step by step by Jiang Yan. He felt that he really made a lot of money this time. Sent.

There are only a few precision-section machines in the country. I have been thinking about dismantling him for a long time, and this time I really got my wish.

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

"Wang Gong, prepare to install the screw rod." Jiang Yan gave the order directly to Wang Tianlai who was standing there.

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

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

Although the screw has been tested to be accurate after manufacturing, it does not necessarily mean that there will be no problems after the parts are installed.

To put it simply, although each part is within the allowable error range calculated by itself, after all the parts are assembled, the allowable error will further expand.

In other words, the error tolerances of the two parts can be superimposed on each other or increase the tolerance. To a large extent, this tolerance affects the overall performance of the machine and even affects the life and accuracy of the machine.

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

Therefore, the worst result calculated by Jiang Yan did not appear here.

Therefore, a skilled worker plays an irreplaceable role in repairing parts. Jiang Yan decided that if he only stayed in the factory for one day, then the repair of parts must be handed over to Sun Deshui and others.
