Chapter 233, Dry

In the following time, Engineer Shen looked at the drawings and asked Jiang Yan without listening, and Jiang Yan also took the trouble to look at the drawings and explain to him.

Jiang Yan also called Master Sun over from time to time to explain to this Shen engineer the difficulty of making parts and repairing parts.

This back and forth, the two of them communicated for more than half an hour, and there were a lot of problems on the drawing.

The others were confused, but Wang Tianlai and Zhang Xiang, who were listening to Jiang Yan and Engineer Shen's communication next to them, benefited a lot, and once again updated their views on the installation drawings.

After chatting about the same, Jiang Yan said to Engineer Shen: "Shen Gong, we are communicating in private about other situations, and the most important thing now is to install this finishing machine." ”

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

Today I came to learn how to install and repair the precision forging machine, and I didn't discuss the problem too much.

He said a little embarrassed: "I'll help you, and by the way, I'll also learn from Jiang Gong." ”

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

After the modesty, Jiang Yan began to instruct the workers and engineers in the workshop to install the finishing machine.

The workers shouted the trumpet and lifted the bases of the 100-kilogram lathes under the command of Jiang Yan, and these bases were spliced together like stacked blocks.

In less than half an hour, the machine base of the finishing machine was completely spliced.

Next, it is necessary to install the corresponding other parts on it, the installation of these parts is the most important and the most delicate, and it 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 element in a mechanical system, it is an important guiding device, used to support the mechanical device, coordinate its movement. Under normal circumstances, bearings have a load-bearing effect, and their failure directly affects the safe operation of the transmission system.

The old shaft in this finishing machine has long been damaged, and the shaft made by the lathe is not up to standard, and the shaft after rough machining is finished by Sun Deshui with his two apprentices.

Just to build a qualified shaft like this, Sun Deshui took his two apprentices to work for three days.

Its accuracy and polish are much higher than those of the shafts installed above.

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

After the installation, Wang Tianlai hurriedly stepped forward with a ruler to measure whether the installation position was correct and whether it deviated from the predetermined track.

After measuring, Wang Tianlai gave everyone a thumbs up, and seeing Wang Tianlai's thumbs up, Jiang Yan breathed a sigh of relief.

The installation of the shaft is the most important step in this machine, and if this step is wrong, basically everything will go wrong.

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

"Wang Gong, this screw is turned three times, and then half a turn."

"Shen Gong, Zhang Gong, the screw installation is in accordance with the standard I said."

Seeing that Wang Tianlai and they tightened all the screws, Jiang Yan hurriedly spoke.

"Isn't it as tight as possible?" Wang Tianlai asked Jiang Yan puzzled.

Hearing Wang Tianlai's question, the other two engineers also looked at Jiang Yan with puzzled expressions.

Seeing their puzzled eyes, Jiang Yan put the intention of Engineer Hansiguo about screwing back half a circle.

"It turns out that this is the reason, this Hansi country is worthy of being able to produce top machine tools, and it is really unique, even the installation of a screw has so much attention, Jiang Gong, if you don't say, we really don't know, there are twists and turns."

The reason why Hansiguo 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 Hansiguo's early research and development of high-end machine tools. Hans began to develop machine tools around the 80s of the 19th century, and by 1969, his machine tool exports had occupied the first place in the world.

Hansi national machine tool not only developed earlier, but also the entire machine tool industry chain has a layout, a large number of their domestic enterprises directly or indirectly engaged in the machine tool industry, in scientific research also has a lot of money and manpower invested in it.

Therefore, Hansguo machine tool is not only the world's leading, but also in the continuous development.

Even if the later generations have the ability to develop machine tools, they are not as good as Hans in the field of high precision of machine tools.

With the addition of various parts, the machine tool gradually plumped up, and the speed of the three people couldn't help but speed up.

Seeing that it was already noon at this time, Jiang Yan and the others had no intention of stopping.

Zhao Changche beckoned to his secretary, and the secretary ran over.

"Little Sun, you go to the cafeteria to add a meal to them." After saying this, he took out a few meal tickets from his pocket and handed them to him.

After seeing his secretary take over the meal ticket, Zhao Chang turned his head and said to Guo Jianjun again: "Xiao Guo, you will also go to help, bring all the food, I will see if it will be over in a while." ”

After Guo Jianjun answered, he followed Secretary Sun out.

"Jiang Gong, let's install something next."

Engineer Shen asked Jiang Yan in a somewhat excited tone.

As a technical idiot, he was so happy today, today he not only saw the detailed installation drawings of this precision section machine, but also was taught by Jiang Yan hand in hand, and felt that he really made a lot of money this time.

There are not many of these fine section machines in the country, and he has been thinking about dismantling him for a long time, and this time he really got his wish.

Jiang Yan heard Engineer Shen ask, did not say anything, and took a ruler to measure the installed machine again, and the installation errors were within his own design.

"Wang Gong, prepare for the installation of the screw." Jiang Yan gave a direct order to Wang Tianlai, who was standing.

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

The installation of the screw is a key place in the whole finishing machine. It is related to the accuracy of the whole machine.

Although the screw rod has been tested for accuracy after manufacturing, it is not necessarily free of problems once the parts are installed.

To put it simply, although each part is within the allowable range of its own calculated error, after all the parts are assembled, this allowable error will be further expanded.

That is to say, the error tolerance of the two parts can be superimposed on each other or increase the tolerance, which to a large extent, affects the overall performance of the machine, and even affects the life and accuracy of the machine.

But fortunately, the newly produced parts were all completed by Sun Deshui with his two apprentices, and the parts they made were better than the original parts.

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

Therefore, skilled workers have an irreplaceable role in the repair of parts, Jiang Yan decided that as long as he stayed in this factory for one day, then the repair parts must be handed over to Sun Deshui and them to complete.
