Tanaka Yongji's heart chuckled, and he heard the voice of Red's words, that is, the past glory cannot be counted, and whether GM cooperates with Xihu this time depends on the current performance of Xihu Company. If Xihu's plan does not satisfy GM, GM does not mind looking for some "new experiences" with other companies, and this other company is naturally Hanhua Heavy Industries, which submitted a plan to GM two days ago.

GM is a customer, and it is the kind of customer that is too big for Xihu to despise, so Tanaka Eiji can only respond to Red's words with a smile. The guests and the host sat down separately, and Rhett said a few words on the scene, and then handed the microphone to Shoji Ryase, who introduced the bidding plan brought by Xihu this time.

For this bidding, Sihu was very well prepared, they made a very beautiful presentation slide, and there were dozens of beautiful sets of explanatory materials. Matsushita helped Shoji Ryase distribute the explanatory materials to the officials and engineers of GM, and Shoji Ryase began to talk about the picture on the large screen:

"Let's see, at the entrance of the entire stamping production line, we have set up an intelligent induction gate, which can be opened and closed at the fastest speed, thereby reducing the leakage of press noise and effectively improving the working environment of the entire stamping workshop."

"Please wait a minute." Locker, an engineer at GM, interrupted Shoji Ryose's introduction, which was not rude, but a normal procedure. If the customer is interested in a certain question, they can interrupt the manufacturer's presentation at any time to ask for technical details.

"Mr. Ryose, this smart sensor gate you designed is very interesting, it can indeed solve the problem of noise leakage relatively well, what I am concerned about now is, because of the addition of such a gate system, how much has the cost of the whole set of equipment increased?"

"About $2 million." Shoji Ryase replied that this figure was not made up by him, but that it had been rigorously calculated in advance. Any improvements made on the existing production line had to be calculated in this cost-effective way, and the $2 million spent to reduce noise was worth it.

Lockell nodded, silent. In his mind, he remembered the plan provided by Hanhua Heavy Industries two days ago, and the other party did not use a complex intelligent sensor system, but skillfully used two doors. When the production line feeds, close the inside door and open the outside door. When the materials are sent in, close the outside door and open the inside door. It doesn't cost much, but it also has the effect of controlling noise.

It can be seen from the comparison of the two proposals between China and Japan that the Japanese side relied too much on technology and had to resort to advanced technology to solve problems that could be solved by some local methods, and the result was self-defeating.

Shoji Ryase continued, "The next step is to pick up the steel plate by a robot and place it on the mold. After analyzing a large amount of data, we found that out of every 10,000 picks, there are 21 times when the pick-up position of the robot is misaligned due to the deviation of the position of the steel plate, resulting in the scrapping of stamped parts. In order to correct this problem, 24 infrared probes are installed on the top of the robot, which can identify stamped parts of various sizes and shapes, and if there is a deviation from the position, the computer can automatically adjust it. ”

"This technology is unique to our company, and we have conducted tens of thousands of experiments in order to obtain the optimal control mode." Eiji Tanaka added.

This technology is a treasure that Xihu Company came to bid for this time, and they have searched all kinds of literature to confirm that no company has solved this problem so far.

"So, what is the cost of this technology?" Locker asked again. ..., "Uh・・・・・・ the cost is relatively large, about $5 million. The main reason for the high cost is that the 24 probes operate in a high-vibration environment, and their detection accuracy is relatively high, so the quality requirements for the components are correspondingly higher. Shoji Ryase replied.

In addition to the technical difficulty, another reason is that the probability of scrapping stamping parts is not high, and the loss is not large, and if the cost to solve this problem is too high, the gain will outweigh the loss. This question was also raised during the internal evaluation of the technology at Sihu, but they eventually incorporated the technology because it would make the press line look a little more modern.

"We do need this technology to prevent the stamping position from drifting, but I don't think we can accept it if we pay $5 million for this technology," Rhett chimed in. Is it possible for you to find an easier way to solve this problem at a fraction of the cost? ”

"We've been looking for technology like that." Shoji Ryase said, "So far, though, we haven't found a better way. $5 million, I don't think that's a big number, is it? After all, the cost of a production line is more than a dollar. ”

Ruide smiled slightly, turned his head to Tanaka Eiji and said, "Tian Gan. With all due respect, would you like to ask, is it possible to control the price of this production line within 10,000 US dollars? You know, we are going to update 4 production lines this time, if possible, our overseas factories will also update the same production line, if your price can be controlled within 10,000 dollars, I think we will be more likely to cooperate. ”

"$80 million? This ・・・・・・" Tanaka almost blurted out "impossible", but he tried to swallow the words back and replaced them with a more euphemistic expression: "Mr. Rhett, I think our costs are relatively transparent, and if the price is reduced to less than 10,000 yuan, we will have no profit at all." As you know, we invested a lot of R&D funds in this project in the early stage, and if there was no profit, we would not be able to recover these R&D funds. ”

Rhett shrugged his shoulders and said lightly, "If that's the case, then okay, please continue to introduce your technology." ”

Shoji Ryase only felt a chill in his heart, the other party's expression showed that they had given their plan a very low score, and if the later introduction could not have special highlights, I am afraid that there would be no chance of winning this bid.

"Well・・・・・・ our entire stamping cycle time is 12 pieces per minute, and if it is an aluminum profile, it can be increased to 14 pieces per minute, which is already the best technology in the world so far." Shoji Ryase stumbled.

Locker shook his head and said, "No, Mr. Ryose, you're talking about the technology of the past, the best technology at the moment, which can easily reach 18 pieces per minute, and I mean steel stamping parts. ”

"It's impossible!" Shoji Ryase blushed and retorted, "It's completely impossible!" ”

"Why?" Locker asked with a smile, in fact, before this, he also thought that the stamping cycle 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 that in fact, there is always a way.

Shoji Ryase said, "If the robot uses a vacuum suction cup to pick up stamping parts, then the acceleration during pick-up will be limited by the suction power of the suction cup. The suction power of a vacuum suction cup cannot be increased infinitely, because this is affected by atmospheric pressure...... Unless someone has the whims, being able to apply two atmospheres on the production line. We have carried out theoretical calculations, under the most ideal conditions, the speed at which the robot picks up stamped parts can only reach 14 pieces per minute, which does not take into account any resistance and other factors, and in fact, this ideal condition is impossible to achieve. ..., this principle is actually not complicated, Shoji Ryose understands, Locker also understands, Donnie Yen also understands, this has always been the bottleneck of the speed of the stamping line. However, Wang Haisheng's inspiration broke this iron law, he did not start from improving the suction power of the suction cup, but added a bottom-up thrust to the stamping part, so as to solve the contradiction of insufficient suction, so that the stamping beat easily rose to 18 pieces per minute.

After seeing Hanhua's plan, Locker had a feeling of amazement. This solution is so simple, that is, after the stamping is completed, when the robot picks up the stamping part, the following die is synchronously pushed upwards for a section. To achieve this, only need to add four hydraulic rods under the mold, for enterprises engaged in forging equipment, the design of several hydraulic rods is simply commonplace.

18 pieces per minute and 12 pieces per minute, the whole difference / work efficiency, equivalent to the original 1 production line into 1. This performance improvement fascinated the people of General Motors, so that they ignored the defect that Hanhua Heavy Industries had no previous experience in producing similar equipment.

"Mr. Ryose, we just got a design that can reach 18 pieces per minute, and according to the simulation on the computer, our engineers confirmed that this speed is completely justified, and it is even possible to exceed it. So, I think, is your company a little too conservative in terms of design thinking? Lockell said.

"The plan you got? Do you mean, the plan of Hanhua Heavy Industries? Shoji Ryase asked, ignoring the rules.

Locker turned his head to look at Red, asking if he could reveal this information. Rhett nodded, and Locker said, "Mr. Ryose, you are right, this is indeed the plan of Hanhua Heavy Industries.

"It can't be! It's completely impossible! Shoji Ryose's eyes were red. Before leaving, they analyzed the advantages of Hanhua Heavy Industries in this bidding, and everyone agreed that Hanhua's advantage should be in terms of price, and Hanhua may lose money and make money, and the price will be very low. But everyone is very disdainful of Hanhua's technology, and they never thought that it would be the case if they couldn't compare with 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!
