"We can't leave the Japanese with any chance!"

As if a little telepathically, just when the management of Xihu Company threatened not to leave any chance for the Chinese, in the Hanhua Institute of Technology and Information at the foot of Beijing's Xiangshan Mountain, Donnie Yen was also vowing his determination to a group of executives and experts.

"Xihu Company is an old enterprise engaged in stamping equipment, with brand and reputation advantages. We are a latecomer, and we can't compare to Sihu in terms of customer trust. So, if our product is not significantly superior to Sihu, then the possibility of being eliminated is very high. ”

"Zifei's idea is right, the Americans are not bad for money, we can't win completely by price, but we must at least not be weaker than Xihu in terms of performance, and then compare the price advantage. Of course, the best thing to do is to have a lower price than Sihu and a better performance than Sihu. However, to do so, it will take ten times as much effort from all the experts here. Lin Zhenhua, who was in charge of presiding over the meeting, said to everyone.

"I think there is still hope for performance that is at or near the level of Sihu. As for saying that it is superior, or even significantly better, than Sihu, I think it is a bit too ambitious? Wang Haisheng, head of the technical department from the machine tool company, questioned.

"Please introduce this question." Lin Zhenhua pointed at Donnie Yen and said.

Donnie Yen nodded, took out a large drawing, and a staff member stepped forward to help him hang the drawing on the wall at the top of the conference room so that everyone could see it.

Donnie Yen took a wooden stick as a whip and began to introduce to everyone:

"Modern automobile production is roughly divided into four links, namely stamping, welding, painting and final assembly, of which stamping is the first process. Everyone, this is the process flow of an automobile stamping production line. ”

Donnie Yen's drawing is very good, from the picture, you can clearly see that the whole stamping process is divided into several steps, such as destacking, cleaning, centering, and stamping.

At the front end of the production line, neatly stacked automotive steel plates are hoisted onto the destacker by a crane crane, and a manipulator with suction cups automatically sucks up a steel plate and feeds it into the production line. There are two washing machines on the production line, which are capable of surface cleaning of the incoming steel sheets to ensure that the steel sheets are clean. Subsequently, several groups of loading manipulators and unloading manipulators respectively feed the steel plates into a series of presses for several stampings. Between the presses, there are special conveyor belts or trolleys for feeding. The stamped workpieces are finally sent out of the production line and into the next process.

Next to the production line, there is also a special device for changing molds. On the same production line, it is possible to stamping different shapes of car shells, or coverings, in the same line. Judging from the figure, the equipment for changing the mold is also automatically controlled, and there is no need for human intervention.

Some of these experts have already been involved in the design of the production line in the early stage and are familiar with the process. Some of them have just been invited to give advice, and when they see such a large-scale production line, they can't help but feel a little bloody.

"Zifei・Is this the production line you have designed so far?" Wang Haisheng asked.

Donnie Yen nodded and said proudly: "That's right, this is the production line we have designed so far." We have consulted all the information we can find, and we have conducted dozens of visits to automobile factories in Japan and abroad, and I dare say that this line represents the latest design concept in the world today, and it is impossible to exceed this level of design by Sihu. ”

"If that's the case, then what are you looking for all of us for?" Wang Haisheng was surprised. He has been working in machinery for so many years, and he can be regarded as well-informed. In his vision, this production line can indeed be regarded as the first-class level in today's world, and he really can't think of what needs to be improved. …,

"Idea, I need a new I button" Donnie Yen said with his hand on his head, "The entire structure of the production line, basically it is impossible to make any major adjustments, but how to innovate in the details, we are now very troubled." The people in our project team may have been working on this project for too long and their thinking has been rigid. Mr. Lin suggested that we brainstorm and work together to find some bright spots, and I will invite you all over. ”

"Every detail has room for optimization." Lin Zhenhua said, "With the development of automatic stamping production lines to today, it is difficult to innovate in terms of the overall pattern. But we can win in the details. If we can optimize every detail, then in the eyes of the customer, it is a completely new concept of equipment. Therefore, I asked Zifei to invite everyone over, which is specifically to optimize various details. Everyone, be patient, stay here for ten days and a half months, and give full play to your ingenuity. ”

"Let me give you an example, it can be regarded as a brick throw." Yao Heliang, an old professor at Huaqing University, said. He walked to Donnie Yen's hanging drawings, pointed to one of them, and said to everyone: "Let's see, the technical trend of today's automated stamping production line is to use manipulators to realize the transfer of stamping parts between various stamping machines. The manipulator has to extract the stamping parts from the stamping machine, relying on these two vacuum suction cups at the top. The suction power of the suction cup comes from atmospheric pressure, and there is an upper limit. In order to avoid the stamping parts falling off during the extraction process, the manipulator's movements must be strictly controlled to avoid additional resistance due to the large acceleration of E. At present, the entire production efficiency of this production line is affected by the speed of the manipulator, and it is difficult to further improve. ”

Donnie Yen added: "What Professor Yao said is a technical bottleneck that we are facing. According to what we have learned, the best production line in foreign countries is to stamping 12 pieces a minute, and we hope to increase this speed to 18 pieces, but we have never been able to solve the efficiency problem of the manipulator. ”

"That's the technical bottleneck you're having?" Wang Haisheng said, "What do I think, this matter is quite simple. ”

"What, you say it's simple?" Donnie Yen's eyes stood up, "Lao Wang, if you can solve this matter for me, I will give you credit for it." Mr. Lin is also here, I will apply now, who can solve this technical problem, please ask the company to reward him with 10,000. ”

The technical staff of the GCA Group often meet together to solve technical problems, and they are very familiar with each other and speak casually. With Wang Haisheng's number, it is enough to be Donnie Yen's uncle, but Donnie Yen still directly calls him Lao Wang.

"Is that true?" Wang Haisheng said, "Mr. Lin, did you hear me?" ”

Lin Zhenhua smiled and said: "No problem, if Zifei says so, then do as Zifei said, if you can really solve this technical problem, it is indeed not much." ”

The question that Yao Heliang just said does sound quite simple at first glance. The car shell is a smooth steel plate, and a steel plate can be lifted up by sucking on it with two vacuum suction cups, which is the principle that the manipulator can handle the steel plate. However, the suction power of a vacuum suction cup is limited, and it is only a little heavier than that of a steel plate. If you extract slowly, there is no problem, but if you want to extract quickly, you need to add an additional force required to generate acceleration, which is beyond the range of suction cup suction.

Because of this, the robot can only accelerate slowly when extracting the steel plate, which makes it impossible to further increase the speed of the entire production line.

To increase the suction power, of course, there are also ways. One way is to increase the area of the suction cups or increase the number of suction cups, but the position of the suction cups on the stamping part is limited, and for some shapes of stamping parts, too large suction cups may not find a suitable place at all. Another way is to change the vacuum chuck to an electromagnetic chuck, but this suction cup will not be able to do anything with aluminum stamping parts. You can't always design two different suction cups on one manipulator, right? ..., it is precisely because this question does not sound complicated that Wang Haisheng involuntarily said the word "simple". But Donnie Yen, Yao Heliang and others have pondered this question countless times, and they can't figure it out. Hearing Wang Haisheng say this at this time, Donnie Yen couldn't help but promise a high reward.

Lin Zhenhua was not too involved in this project, but he had participated in several technical seminars before and knew that this problem was a big problem. He himself had thought about this problem, but naturally he could not find any ideal solution. In his opinion, if there is really someone who can solve this problem perfectly, then Wan's reward is really not outrageous.

"Okay, I'll take it, I'm willing to cut it all my body, I don't believe it if I dare to pull the emperor off the horse, isn't it just a matter of two suckers, give me a month, if I can't solve it, let Mr. Lin remove me." Wang Haisheng said angrily.

"Remove from your post and be dismissed, we are a group of heroes, we have merit in solving the problem, and we are not guilty if we don't solve the problem." Lin Zhenhua said, "Zifei and their colleagues will be with the Department of Mechanical Engineering, the Department of Automation and other units of Huaqing University, and they have been engaged in it for so long, and the problems they have not solved must be solved in a short time, which is also unrealistic." Therefore, there is no pressure on our tackling key problems, and everyone lets go of their ideological baggage. By the way, next to our base is Xiangshan, the scenery is very good, everyone has nothing to go to visit. ”

With Lin Zhenhua's words, the experts present were all relaxed. If you solve the problem, you can reward 10,000 yuan, and if you don't solve the problem, you can enjoy the treatment of visiting Xiangshan every day, where to find such a good thing. The crowd raised their hands and began to claim the problems to be solved. Donnie Yen had already sorted out some written materials for the problems encountered by the project team, and then took them out and distributed them one by one. There are even those technicians who are in a hurry, and they come directly to the drawings and start chatting fingers. To be continued. If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. T himself dug a hole, the automobile stamping production line, there are really no technical highlights to write about, but when it comes to writing, I can only make it up blindly.

Orange checked the information for a day today, and made up a few ideas by himself, don't be more serious to readers who know how to design this, if Orange could design this, he would have become an academician a long time ago. … ・・・・・・・・・ recommend this book to everyone, I don't know the author, and I didn't recommend it, I saw this book by chance, I think it's really good, and I can't help but recommend it to everyone. The book is an urban book, called "Official Road 1976", and the name is quite vulgar. At first glance, the author's writing is from a traditional literary background, and the choice of words and sentences, the grasp of narrative style and details are very sophisticated, and there are few such writing among online writers. The story is by no means traditional, and the layout and cool point settings are very in line with the style of online novels. Personally, I feel that this book will be popular.
