Siheyuan: I can simplify skills

"Time! How long is the total time?" Xu Yang asked.

"It took a total of two hours. But we completed the processing of five workpieces, and it took an average of 24 minutes for each workpiece." Guo Dapizi said.

"Actually, if the time was longer, it would take less than 24 minutes." Xu Yang said.

"That's right. If we keep working all the time, the time spent on each workpiece can be shortened by a few minutes if we divide the free time in the front and the back equally. In addition, we are not proficient enough now. I estimate that after becoming proficient, the time consuming can be reduced at least. Four to five minutes," Zhao Xiangdong said.

"If you think about it this way, wouldn't it be much faster than our previous processing speed?" Guo asked.

Director Guo smiled and said: "It's much faster."

Secretary Yang was very excited: "I will contact the key units immediately and we will finalize this batch of tasks!"

Secretary Yang walked outside and ran back: "I will arrange the canteen to prepare a celebration banquet for you to improve the workshop! Everyone, have a good rest."

Director Ma gave him ten days, but it took only one week for the improvement workshop to adjust the production line and complete trial production.

Director Ma was also surprised when he received a call from Secretary Yang.He did not expect that the steel rolling mill would improve its workshop so quickly, and he also did not expect that Xu Yang's 4.8 methods would be so outstanding.

"Secretary Yang, we may have to pay a visit to your factory today. Let's take a look at the assembly line of your steel rolling mill." Director Ma said.

The assembly line is definitely a new thing in this era. Even in developed countries, its application is not very widespread.Now that it is being used in steel rolling mills, how could Director Ma not be surprised and excited.

"Warm welcome! Director Ma, this batch of artifacts must be ours, right?" Secretary Yang said.

"I will definitely not miss you. But this time Beigang has introduced imported equipment for this purpose, and some of it must be given to them. They seem to have completed equipment debugging. They should be able to start formal production soon. All we can do is A bowl of water is level. But from now on, whoever has higher accuracy and better quality will be assigned the task!" Director Ma said.

"Just give it to us, we are definitely the best in quality. The minimum standard for improving the workshop is excellence. If it is not excellent, it will not leave the factory." Secretary Yang said.

"What you did is good. It's safest to use your workpieces." Director Ma smiled.

On the same day, Director Ma and his party rushed to the steel rolling mill. After all, it was close.

Xu Yang did not expect to see the mechanical department team again so soon.

"Xiao Xu, you released a big satellite! You actually took the lead in starting the assembly line operation." Director Ma said with a smile.

"I just gave it a try, and I didn't expect the effect to be quite satisfactory." Xu Yang said with a smile.

"We just lack front-line technicians with brains like you. You are more useful than experts and scholars like us in the ivory tower. Because you understand production and technology. You also have strong research and development capabilities." Director Ma said .

Chapter 111 Problems with imported equipment

The machines at Beigang are also being debugged. Beigang is larger than the rolling mill, and its technical capabilities are much stronger.

Chief Engineer Li Zhiliang is a well-known figure in the industry.

Otherwise, the good thing about introducing imported equipment would not befall them.

However, at this time, they did not know the news that the Kyoto Steel Rolling Mill had successfully processed the latest workpieces for key units.

"We must get the processing task this time. Although the equipment we introduced is not the most advanced in the world, it is definitely the best in the country. Domestic machine tools are absolutely incomparable in terms of accuracy." Li Zhiliang said .

Ding Kecheng, director of Beigang, is a little worried: "I heard from Director Ma of the Department of Mechanical Engineering that the rolling mill is developing new processing equipment, and they are likely to compete with us."

"I have heard about the machine tools they designed. They were designed based on the Da Mao machine tools that were built with Da Mao's aid. Even if the performance is improved, I guess the improvement will not be very big. You know, at that time, Da Mao's aid When it was built, the equipment given to us was already obsolete from Da Mao at that time. Da Mao was always on guard against us," said Li Zhiliang.

"No matter what, we still need to debug the machine tools first. While the foreign experts are here, we must master the use of these machine tools. Give full play to the superior performance of these advanced machine tools." Ding Kecheng said.

Beigang also attaches great importance to this matter. The chief engineer, engineers, factory technicians, and senior fitters all participated in the debugging of the machine.

Under the guidance of foreign experts, the machine quickly completed installation and debugging and began processing.Demonstrates very excellent processing capabilities.

Of course, the workpieces they use for trial processing are not difficult workpieces, but ordinary parts.

The performance of this batch of machine tools is indeed good, with high precision and very good processing stability.Compared with Da Mao's machine tools, it is indeed much more advanced.

After the introduction of the machine tool was successfully put into operation, Beigang also held a grand celebration banquet.

Then start processing the workpieces of key units.

But the result was not ideal.

The processing difficulty of these 26 batches of workpieces in key units is much more difficult than the workpieces they tried to process.Moreover, this batch of artifacts is confidential, and foreign experts cannot be used for guidance.

Beigang's technicians seem to have mastered the operation of machine tools, but they are still in the process of having a partial understanding.It is okay to process ordinary workpieces, but it is very difficult to process such high-precision parts.

Several batches of workpieces were processed without success.

"Unqualified? What happened? Didn't you say that you have mastered the use of the machine tool? The processing accuracy range is also within the accuracy range of the machine tool, how could the processing fail?" Ding Kecheng was furious when he heard the news.

Having spent so much foreign exchange on imported equipment, we just held a celebration banquet, and when we turned around, we were slapped hard in the face.

Li Zhiliang frowned: "The precision requirements for this batch of parts of the Academy of Science and Technology are very high. The most important thing is that these parts are special-shaped workpieces, which are relatively difficult to process. The operators are not familiar enough with the machine tools. Every time they change the processing surface, It is difficult to achieve [-]% accuracy in the adjustment of the fixture. This is the main reason for processing failure. There is no problem with the accuracy of imported machine tools. It is a problem of use."

"If it doesn't work, try a few more times! Even if it's a pile of materials, the operator must master the use of the machine tool." Ding Kecheng is still very determined.

Several specialized operators at Beigang also worked consecutive shifts, and the machine tools never stopped.

But the processed workpiece has problems either here or there.

Engineer Wu Lianjun looked at the scrapped workpieces spread out on the floor and almost burst into tears.

"The accuracy of machine tools is sufficient, so why do problems always occur?"

Jia Duoyi, an eighth-level fitter, said: "During processing, the machine tool seems to shake from time to time. Then the surface being processed will fail the inspection. I think there is no problem with our operation. It is the machine tool that is unstable."

"It's impossible. This is a new machine tool. The processing accuracy we set is within the accuracy range of the machine tool and is not close to the critical value. Logically speaking, it can be processed." Wu Lianjun said.

"How about we try again." Jia Duoyi said.

When processing again, I found that the machine tool was shaking accidentally.

"It was shaking just now. I think the processing of this noodle is suspended." Jia Duoyi said.

Jia Duoyi marked this processing surface.

After the processing was completed, inspection was conducted and it was found that there was indeed a problem with the processing of that surface.

Beigang found the problem, but Li Zhiliang was unable to solve it.The foreign experts had already left after the celebration banquet.It will cost a lot to invite people back now.

When Ding Kecheng explained the situation to Director Ma of the Mechanical Department, he received even worse news. The steel rolling mill had begun to provide them with workpieces, so Director Ma told Ding Kecheng not to rush, to take his time and find out the problem.Even if this batch of workpieces is not caught up, important workpieces can still be handed over to them for processing in the future.

Can this situation not be urgent?Ding Kecheng almost died of panic.Am I worried that your workpieces will not be processed?

The steel rolling mill completed the workpiece processing with self-developed equipment, while Beigang introduced expensive imported equipment, but the processing failed.As the director of Beigang Factory, this matter is going to end!

"This is impossible? Can the rolling mill have the technical capabilities to develop equipment with such high precision? Moreover, the processing of these workpieces is so difficult, how could they complete it?" Li Zhiliang couldn't believe it.

"They have already sent the processed workpieces to key units! What else is possible? And Director Ma said that the quality of this batch of workpieces is very high, and they are all top-notch products! But we can't even process qualified products!" Ding Kecheng said.

Li Zhiliang frowned, this was troublesome.If it is not resolved in time, both he and Ding Kecheng will suffer.

This is a very significant loss!It is possible for two people to be imprisoned.

Xu Yang was very surprised that Beigang's imported equipment could not successfully process this batch of complex workpieces.After all, this batch of imported equipment from Beigang was originally introduced to process high-precision workpieces.

"This is a great thing for us. This batch of workpieces from key units has all fallen on us." Director Guo said with a smile.

"But the country has lost a lot of money. The equipment that was imported at a large price cannot be used. This loss is not small." Xu Yang said.

"Yes." Director Guo sighed.It should be that Beigang has not yet mastered the use of machine tools.

Xu Yang didn't think so: "It's also possible that someone else deliberately dug a hole for us. Not all foreigners are white doctors."

Beigang has not been able to solve the problem of machine tools.In the end, I could only turn to the Mechanical Department of Qingda University for help.

Director Ma and other experts were invited to conduct consultations on imported equipment.

But faced a problem.After the machine tool is disassembled, it no longer belongs to the manufacturer's scope of repair.Without disassembling the machine, you will not be able to master the maintenance techniques of the machine tool.Will always be controlled by others in the future.More importantly, the introduction of this batch of advanced equipment is not just for processing high-precision machine tools, but for learning foreign machine tool technology.

Professor Wei specially brought the student Xu Yang there.

"This opportunity is rare, so I called you here. Aren't you designing a new generation of machine tools? Maybe imported equipment from abroad will inspire your research." Professor Wei finally secured a place for Xu Yang.

"Thank you, teacher." Xu Yang was very touched.

We haven't been with this tutor for long, but he really takes good care of me, a cheap student.

Beigang is very enthusiastic about the experts in the mechanical department.Factory director Ding Kecheng and chief engineer Li Zhiliang greeted them personally.

"Director Ding, let's not be polite. Let's go see the machine tools first. This is the purpose of our visit," Director Ma said.

Ding Kecheng nodded: "Okay, I won't be polite. I'm getting angry now. The equipment imported at such a high price is not as good as the equipment developed by the steel rolling mill itself."

Professor Wei smiled: "The engineer who developed that equipment happened to be here today."

"Ah?" Ding Kecheng was a little confused, why did the engineer from the steel rolling mill come here?Come and see our Beigang jokes.

"Xiao Xu is a graduate student in our Department of Mechanical Engineering. He is a student under the guidance of Professor Wei. This is a rare opportunity, so Professor Wei applied to bring him here. Although he is only an engineer, he is very capable in the field of machine tools. Steel Rolling Plant The machine tools have been completely upgraded twice. The technology has been upgraded several times. Each time, the accuracy has been greatly improved. Especially the latest upgrade has created a precedent for our domestic assembly line operations." Director Ma said.

"Young man, you are really awesome!" Li Zhiliang extended his thumb.Li Zhiliang asked himself that he couldn't even develop a new machine tool.Even on the basis of large-scale machine tools.Domestic companies have copied Da Mao machine tools before, but let alone improving performance, it would be good if they could reach the level of Da Mao machine tools.

Xu Yang can continuously improve the accuracy of machine tools, which is really amazing.

"Xiao Xu, we have to work hard this time to help us find the problem." Ding Kecheng said politely.

He didn't think Xu Yang could solve Beigang's technical problems, but Xu Yang was young.And being valued so highly by Director Ma is obviously not simple.Just because you can't help this time doesn't mean you won't be able to help in the future.It is impossible for such a powerful talent to stay in a small steel rolling mill.

"I'm here to learn this time," Xu Yang said.

When we arrived at the workshop, the imported machine tools had stopped.

"In fact, everything was normal during processing, and there were no problems with our operations. However, every time during processing, the machine tool would occasionally vibrate abnormally, causing processing to fail." Wu Lianjun said.

"Is there something wrong with the servo motor inside?" Professor Wei said.

"Probably not. This is brand-new equipment. This phenomenon did not occur when we processed ordinary equipment. Once we process high-precision parts, this problem will arise." Wu Lianjun replied.

"What's the problem? The only way is to take it apart and take a look!" Director Ma said.

"Demolish it!" Ding Kecheng said.

Beigang has asked its superiors for instructions on this issue and received approval. Anyway, if you want to learn advanced machine tool technology, you have to take it apart and look at the inner structure.

Even if you can't learn the technology, you still need to master the maintenance technology yourself.Otherwise, every time a problem occurs, the manufacturer will be asked to repair it, and Beigang cannot afford the cost.

Xu Yang felt that there was something wrong with the machine tool's fixture master.There is no problem with adding ordinary parts to the fixture, but the special-shaped workpieces in key units have irregular shapes.A slight deviation during the fixation process will naturally cause jitter during the processing.

Of course, Xu Yang is not completely sure, because during Beigang's processing, the problem did not occur on the same processing surface.

What's more, Xu Yang also wanted to see the internal design of the machine.How could such a good learning opportunity be wasted?Even if you have identified the problem, you have to wait until you have finished studying before speaking.

The machine tool was disassembled, and the structure inside was indeed much more complex and precise than Da Mao's machine tool.

But complexity is actually not a good thing.Definitely more difficult to maintain.It's definitely not as rough-resistant as a big-haired machine tool.
