Chapter 544

Eiji Tanaka's heart skipped a beat. He heard the voice of Ruide's words, that is, past glory cannot be counted. Whether GM will cooperate with Xihu this time depends on Xihu's current performance.If Xihu's plan does not satisfy GM, GM doesn't mind looking for some "new experience" with other companies. This other company is naturally Hanhua Heavy Industries, which submitted the plan to GM two days ago.

GM is a customer, and it is the kind of customer that is too big for Xihu to be underestimated. Naturally, Eiji Tanaka can only respond to Rhett's words with a smile.The guests and the host were seated separately, Ruide said a few words on the scene, and then handed over the microphone to Shoji Rase, who introduced the bidding plan brought by Xihu Company this time.

For this bidding, Xihu Company is still very well prepared. They have made a very beautiful presentation slide and dozens of sets of exquisite explanatory materials.Matsushita Yongzo helped Ryase Shoji distribute the explanatory materials to the officials and engineers of GM, and Ryase Shoji began to talk about the picture on the big screen:

"Look, at the entrance of the entire stamping production line, we have set up an intelligent sensor gate, which can be opened and closed at the fastest speed, thereby reducing the noise leakage of the stamping machine and effectively improving the quality of the entire stamping workshop. working environment."

"Please wait a moment." Rocker, an engineer from GM, interrupted Shoji Rarase's introduction. This was not rude, but a normal procedure.If customers are interested in a certain issue, they can interrupt the manufacturer's introduction at any time and ask for technical details.

"Mr. Ryase, the intelligent sensor gate you designed is very interesting. It can indeed solve the problem of noise leakage. What I am concerned about now is how much the cost of the entire equipment has increased because of the addition of such a gate system? "

"About 200 million US dollars." Ryoji Shoji replied, this figure was not made up by him, but was strictly calculated in advance.For any improvement made on the original production line, this kind of cost-effective calculation must be done. According to the analysis, it is worthwhile to spend 200 million US dollars to reduce noise.

Rocker nodded without saying a word.He thought of the solution provided by Hanhua Heavy Industry two days ago. The other party did not use a complicated intelligent sensing system, but cleverly used two doors.When the production line is feeding, close the inner door and open the outer door.After the materials are sent in, close the outer door and open the inner door.It costs little to do so, and it also has the effect of controlling noise.

From the comparison between the two solutions of China and Japan, it can be seen that the Japanese side relies too much on technology, and the problems that can be solved by some local solutions have to resort to advanced technology, which turns out to be self-defeating.

Ryose Shoji continued to introduce: "The next step is to pick up the steel plate by the robot and place it on the mold. After analyzing a large amount of data, we found that in every 1 picks, there will be 2.1 times due to the deviation of the position of the steel plate. As a result, the pick-up position of the manipulator is deviated, which leads to the scrapping of stamping parts. In order to correct this problem, we installed 24 infrared probes above the manipulator, which can identify stamping parts of various sizes and shapes. Once the position deviates, Automatic adjustments can be made by a computer."

"This technology is unique to our Xihu company. In order to obtain the optimal control mode, we have conducted tens of thousands of experiments." Eiji Tanaka added.This technology is a magic weapon for Xihu to bid this time. They have searched various documents and confirmed that no company has solved this problem so far.

"So, what is the cost of this technology?" Rocker asked again.

"Uh... the cost is relatively high, about 500 million US dollars. The main reason for the relatively high cost is that these 24 probes work in a strong vibration environment, and their detection accuracy is relatively high. Therefore, the quality requirements for components have also increased accordingly." Shoji Ryose replied.

He knows in his heart that the cost problem is the biggest shortcoming of this technology. The stamping production lines provided by other manufacturers generally do not solve this problem. In addition to technical difficulties, another reason is that the probability of stamping parts being scrapped is not high. The loss is not too big. If the cost to solve this problem is too high, the loss outweighs the gain.This issue was also raised when Sihu was evaluating the technology internally, but they ended up integrating it because it would make the stamping line look a little more modern.

Rhett interjected, "We really need this technology to prevent punching from being out of position, but if we have to pay $500 million for this technology, I don't think we can accept it. Is it possible for you to find an easier way that costs Not much, can this problem be solved as well?"

"We have been looking for such a technology." Ryoji said, "However, so far, we have not found a better way. I don't think 500 million US dollars is a big number? After all, a production line cost over $1 million."

Ruide smiled slightly, turned to Tanaka Yongji and said: "Mr. Tanaka, please forgive me for inquiring, is it possible to control the price of this production line proposed by you within 8000 million U.S. dollars? You know, this time we To update 4 production lines, if possible, our overseas factories should also update the same production line, if your price can be controlled within 8000 million US dollars, I think the possibility of our cooperation will be greater.”

"8000 million U.S. dollars? This..." Tanaka Eiji almost blurted out, saying "impossible", but he tried hard to swallow the words back, and changed into a more euphemistic way: "Mr. Rhett, I I think our costs are relatively transparent. If the price is lowered below 8000 million, we will have no profit at all. As you know, we invested a lot of research and development funds for this project in the early stage. If there is no profit, we will There is no way to recover these research and development funds.”

Rhett shrugged, and said lightly: "If this is the case, then well, please continue to introduce your technology."

Ryose Shoji just felt chills in his heart. The other party's expression showed that they had already given their proposal a very low score. If there were no special highlights in the introduction later, his bidding this time would be nothing. Odds are good.

"Well... Our entire stamping cycle is 12 pieces per minute. If it is an aluminum profile, it can be increased to 14 pieces per minute. This level is already the best technology in the world so far." Ryose Shoji knocked Baba said.

Rocker shook his head and said, "No, Mr. Ryase, what you are talking about is the past technology, the best technology at present, which can easily reach 18 pieces per minute. I mean steel stamping parts."

"It's impossible!" Ryose Shoji retorted with a blushing neck, "It's absolutely impossible!"

"Why?" Locker asked with a smile. In fact, before that, he also believed that the stamping beat of 18 pieces per minute was impossible to achieve, but the plan provided by the Chinese two days ago convinced him and let him know, In fact, there is always a way.

Ryoji Akira said: "If the manipulator uses a vacuum suction cup to pick up the stamped parts, then the acceleration when picking up will be limited by the suction force of the suction cup. It is impossible to increase the suction force of the vacuum suction cup infinitely, because it is affected by the atmospheric pressure... …Unless someone is whimsical and can apply two atmospheres of pressure on the production line. We have performed theoretical calculations. Under the most ideal conditions, the speed at which the manipulator can pick up stamping parts can only reach 14 pieces per minute, regardless of any factors such as resistance In fact, this ideal condition is impossible to achieve."

This principle is actually not complicated. Ryoji Shoji understands it, Rocker understands it, and Donnie Yen also understands it. This has always been the bottleneck of the speed of the stamping production line.However, Wang Haisheng had an idea and broke this iron law. Instead of increasing the suction force of the suction cup, he added a bottom-up thrust to the stamping parts, which solved the contradiction of insufficient suction force and made the The stamping beat easily rose to 18 parts per minute.

After seeing Hanhua's plan, Rocker was amazed.This solution is so simple, that is, after the stamping is completed, when the manipulator picks up the stamped parts, the mold below is pushed up a section synchronously.To achieve this, it is only necessary to add four hydraulic rods under the mold. For enterprises engaged in forging equipment, designing several hydraulic rods is simply a matter of routine.

18 pieces per minute and 12 pieces per minute, a full difference of 1/2 work efficiency, which is equivalent to changing the original 1 production line into 1.5. This improvement in performance has fascinated the people of General Motors, so that The defect that Hanhua Heavy Industry had no experience in producing similar equipment was ignored.

"Mr. Liangse, we just got a design plan that can reach 18 pieces per minute, and according to our engineers' simulation on the computer, it is confirmed that this speed is fully justified, and may even exceed it. So, I Do you think your company is a little too conservative in terms of design thinking?" Rocker said.

"The plan you got? You mean, Hanhua Heavy Industry's plan?" Ryose Shoji asked in disregard of the rules.

Locker turned his head and glanced at Rhett, asking if he could disclose this information.Rhett nodded, and Rocker said: "Mr. Ryose, you are right, this is indeed Hanhua Heavy Industry's plan."

"This is impossible! This is absolutely impossible!" Ryose Shoji's eyes were red.Before setting off, they analyzed the advantages of Hanhua Heavy Industry in this bidding, and everyone agreed that Hanhua's advantage should be in terms of price, and Hanhua might make a profit at a loss and keep the price very low.But for Hanhua's technology, everyone is very disdainful, and never thought that it would be like this if they were inferior to Hanhua in technology.

But now, GM clearly told them: Hanhua's production line can reach 18 pieces per minute, but they can only reach 12 pieces. Such a gap can be regarded as a generation difference. How is this possible!
