60s researcher

Chapter 158

Factory Manager Zhang sighed, feeling very helpless in his heart, this agricultural machinery factory is a bit overreaching.After the planter was developed, Lu saw that they got busy. First, they transformed the production line, and then went to the machinery factory to join the CNC machine tool project team.The agricultural machinery factory now has three kinds of agricultural machinery. Although the Ministry of Agriculture has managed to get some technicians, the salary is a drop in the bucket, and the basic technical support can be maintained. There is no need to think about researching other agricultural machinery, let alone wanting to carry out research on the current agricultural machinery. Upgraded and remodeled.

After all, the agricultural machinery factory has been established for too short a time, and there is no capable and courageous researcher like Lu Jian, so from time to time, he has to borrow people like the electrical appliance factory to help.Director Xu, he saw that it was all for the construction of Xinhuaguo, and he borrowed it every time, but they actually wanted to secretly transfer people to the agricultural machinery factory.Is it easy for them to save their current wealth?

Forget about it, it’s a trivial matter after all, but today the Ministry of Agriculture has to ask them to accompany them when they visit the agricultural machinery factory. How difficult it is, how many people can't get enough to brag about, and what they say is that they want to drop Lu Jian and the others to the agricultural machinery factory, and then specialize in agricultural machinery.I also look down on those who make electrical appliances, thinking that it is just for enjoyment, and it is not important to have a full meal. You must know that their current fertilizer production line and technology are all exchanged with the foreign exchange earned from selling air conditioners.

If he still wants to meet Lu and them, it's just a dream in Director Xu's mind.

Director Zhang thought for a while, and then reminded Director Xu, "Old Xu, you should have a better attitude later, don't be too aggressive, your personal standpoint is different, and you can't say that they are unreasonable, but there are some..." Don't say anything Friendship.

Before Director Zhang finished speaking, Director Xu immediately interjected: "It's just a little despicable and shameless!"

Factory Manager Zhang was speechless. There seemed to be nothing wrong with what he said. It was a bit shameless. The electrical appliance factory had helped the agricultural machinery factory so much and still wanted to poach the wall. If he was the leader of the other party, he would certainly think that they did a good job. The side that was poached.

"Anyway, you should control it when you are eating." This time, the Ministry of Agriculture did not come here specifically to visit the agricultural machinery factory. They mainly inspected the spring plowing situation in various places. You must know that agricultural production is related to the livelihood of the people, and has always been very important. , although industry is the most important thing now, there are still many people who pay attention.So they didn't have much time. They visited the agricultural machinery factory in the morning, had a meal at noon, and then left Hu'an city to inspect the countryside below.

Factory Manager Xu said nonchalantly: "I know, I know, anyway, seeing that they are not coming, Lu will naturally not mess around." Those who want to rob him have no way.

Lu Jian over there didn't even know that Director Xu in the electrical appliance factory was very angry because someone coveted them. Even if he knew, he wouldn't feel bad about it. He would only be more shameless than them, and he might have evacuated all the researchers in the electrical appliance factory.

At noon, Lu Jian quickly finished his meal and went to the small office. Zhou Changming and the others had already arrived, leaving Qi Lao and Lou Lao alone.

Seeing Lu Jian coming in, Lu Xianfeng's eyes lit up, and he pulled him over very eagerly, "Lu Jian, you are here, please help me to see, the machine support of this machining center that rotates integral parts Is there something wrong with the institutional parameters, and it has not been adapted?"

Lu Jian sat next to him, took the blueprint from his hand, "Let me take a look."

Lu Jian took a closer look, and found that the problem was not serious, but Lu Xianfeng had no idea, "Old Lu, it's not that there is a problem with the supporting mechanism. It's that there are other problems. Look here, the fan-shaped plate designed on the drawing Is the angle a bit wrong, it’s better to have six yuan, and the angle is at [-] degrees..."

Lu Xianfeng listened carefully to what he said, and it took him a while to realize that he had made a mistake, and he said helplessly, "I'm getting old, I really can't help it, my old eyes are dim, and I can't even see the problem clearly."

Lu Jian knew that he was joking again, and he himself was not a sentimental person, so he just smiled and said: "Mr. Lu just didn't think of it for a while, even if I don't say it, I will find out soon." This is true, Lu Xianfeng just didn't turn the corner for a while.

While the two were talking, two more people came in, and now they were all there.

Zhou Changming took a look and cleared his throat: "Ahem, cough, everyone is here, then let's start! Lu Gong, you come first."

Lu Jian nodded, he is the youngest, the first one should be, "Our CNC device project team has made preliminary progress, the first chip with 2000 transistors has been made this morning, and the circuit test is now being done, the whole The circuit design has been verified before, and there is a high probability that there will be no problems. The point control system has also been designed and can be used for experiments at any time. There are two goals in the next stage. The first is to increase the number of transistors to about 4000. Another is to compile the control program first." "The general transistor improvement plan is to modularize the circuit design, try to reduce the size of the integrated circuit, reduce the size of the chip, and package more circuits..."

"In terms of control program, the part pattern and process are converted into a digital language..."

Lu Jian spoke very quickly, and many places were only briefly mentioned.

"The current progress of the CNC device project team is like this. Is there any problem?" After speaking, Lu Jian looked at everyone.

Suddenly Zhai Zhiyuan raised his hand, seeing Lu Jian looking at him and nodding, he hurriedly said, "When will your input and output devices start?"

Lu Jian didn't expect him to be so anxious, "After the memory and controller are finished, there are many places to debug, and the data must be correct before proceeding."

"That's it! It's better to make it as early as possible, and it can be corrected after any problems." The design of the numerical control device is closely related to the servo drive device. It must completely receive the digital signal of the numerical control device to drive the machine to run.

Lu Jian nodded, thinking that what he said was correct.

Afterwards, he sat down and began to improve the explanations of others. During this period of time, it was not only Lu Jian who made rapid progress, but Mr. Lu and his main machine tool project team also achieved a lot of success. They have given several types of machining center drawings to It has been designed and is now being demonstrated one by one. The boring machine accumulative machining center used for machining box parts has been produced, but there are still many things to do in the future. You must know that there are really many types of lathes. Although the task is not the most difficult, it is the largest task.

Zhai Zhiyuan, who went up last, is in charge of the servo drive device, which is essentially a drive.Zhai Zhiyuan looked confident.

"This servo drive device has three control methods, including position control, torque control and speed control. The power device will use an intelligent power module as the core drive circuit, and it will have overheat, overvoltage and overcurrent fault protection. device, a soft-start circuit is also added to the main circuit to reduce the impact of starting. "

"Our driving device will use a three-phase full-bridge rectifier circuit, and then use a three-phase sinusoidal voltage inverter to convert the frequency to drive the AC servo motor." At this point, he glanced at Lu Jian and hesitated. Said: "Lu Gong, I heard that you have developed a frequency converter before, can you help us?"

To put it bluntly, the function of the servo drive is somewhat similar to that of the frequency converter, and it is mainly used to control the servo motor.

Lu Jian listened carefully, but did not refuse, "Of course, you can ask me anytime if you have any questions."

Zhai Zhiyuan was very happy, "Then thank you Lu Gong."

This was an episode, and then Zhai Zhiyuan continued talking.

The meeting didn't go on for a long time, it ended at about [-]:[-], and it was just a progress meeting.Zhou Changming seemed very happy. According to the current progress, they will definitely be able to complete the project within the stipulated time, and maybe they can finish it some time earlier.

There were other things to do in the afternoon. Seeing them, Lu saw that they were not prepared to stay longer, and they all got up to leave. Suddenly Zhou Changming called Lu Jian, "Gong Lu, you stay here for a while, I still have something to tell you. .”

Lan Mingda, who was about to go back with Lu Jian, gave them a strange look, "Gong Lu, then I'll go back first?"

Lu Jian stopped and nodded, "Okay."

After everyone left, Lu Jian closed the door, went back to the meeting table, and sat opposite Zhou Changming.

Lu Jian looked at him suspiciously.

Zhou Changming looked at Lu Jian and asked strangely: "Gong Lu, has the Ministry of Agriculture in the capital gone to our agricultural machinery factory?"

Lu Jian was a little surprised, why did he suddenly care about this, "Yeah? Is there any problem?"

"It's not that someone wants to see you, so they called me." He smiled as he spoke.

"A person from the Ministry of Agriculture?" Lu Jian already knew who it was. Could it be that he had to ask Zhou Changming to confirm whether he was really busy through Director Xu? do what.

Zhou Changming nodded, still looking curious, apparently not knowing why they were looking for him, "Ask me to ask if you are busy, if you have a meeting, and when this project will end, I feel like this is trying to poach people, Not only did I ask you, but also Xu Yan and the others."

Lu Jian frowned, "Ask Xu Yan and them what?"

"Ask them if they are important in this project, of course they are, they are all talents."

"Don't worry, I've always said that you are very busy, and their time is also very tight, and they will go to other places in the afternoon." I always feel that they are ready to move and want to attack Lu Jian them.

"That's it!" Lu Jian probably knew, maybe he wanted them to help with the agricultural machinery project again.
