And Wang Lu really gave some guidance, most of which were photos. Wang Lu trained abroad for a long time in the past few years, at General Motors, Detroit, South America.
They all have experience in railway equipment transportation, which is very important to Ji Donglai, as it will save him at least five years of detours.
Among them, the design of two sets of forward buffer plates caught Ji Donglai's attention. They are simple and effective.
Ji Donglai used CAD to simulate the position based on the car model structure given by Wang Lu and the structural plans of other companies' related product designs, and finally designed the product's structure to be 800 long and 600, 400, 200 wide. A few hundred and forty widths.
The entire thickness is 80 degrees, and the hardness of the rubber does not need to be too high, 80 degrees.
As for the material, Ji Donglai used the simplest industrial rubber sheet material, which is also the cheapest. Considering the huge weight of the vehicle itself and the huge friction force of the 60-ton weight on the surface of the buffer material, the buffer material wears gradually. Consume energy.
In fact, most of the energy of the buffer material is concentrated on the columns of the carriage. As long as these points are protected, it is enough. However, according to the requirements of railway vehicle inspection, the overall layout must exceed a certain proportion.
A load-shedding groove is added to the surface, a steel frame is added to the back plate, and the whole is welded to the surface of the car-facing plate.
As for the press beam, according to the car body structure, the steel plate is glued and has a trapezoidal cross-section.
As for the forming mold, it is the simplest. There is no need for machine tool processing at all. The flame directly cuts the grooves out of the 80 iron plate, polishes the surface, and uses bolts to connect the parts.
In terms of molding, the cover is a ten millimeter thick iron plate. The grooves inside are connected to the surface of the base plate with bolts. Each time the mold is opened, it is directly lifted up by hand.
Ji Donglai opened three sets of molds alone, and three 300-ton vulcanizing machines were integrally molded.
After the design was completed here, Ji Donglai directly assigned the task to the rubber mixing workshop, and the mold workshop also rushed to design.
As for Wang Lu, the other party gave some "guidance" symbolically. Ji Donglai immediately took it back to make modifications, and then made plans for various buffer materials. Teacher Wang gave "guidance" again.
In the evening, Ji Donglai had already put all the plans into writing and drawings, and then came to the place agreed with Tan Xiumei.
"Mr. Ji, I'm sorry last time. The different business methods between our two places led to misunderstandings. Please don't mind it! If there was anything I did wrong last time, please forgive me. I'll drink this first as a token of respect. ..."
Compared with the arrogance last time, this time Yu Yang was in a state of begging for help almost the whole time.
Did Ji Donglai take it? After all, it was business, so he didn't let the other party drink as a penalty, but he had a drink with him. The other party wanted to drink, but Ji Donglai stopped him directly.
"Mr. Yu, let's get down to business. Mr. Tan has told me your story in detail. I've been running your business from yesterday to today. I'm not talking about this as a brother. You're doing something wrong!"
"You dare to offend even the people on the railway. Yesterday, I found connections with the power plant's upper and lower staff, and I also found connections outside, and then I started talking to them. But the price you have to pay this time is not small, and the rectification project will definitely be Gotta do it, but some things on your car need to be replaced!”
"I have reached an agreement with them. Some things will be produced here! Then they will be installed on this car. Your original mechanisms will have to be dismantled. It is not because they are making things difficult for you! You have put so much thought into this project. This time They are also teaching you a lesson!"
"But I have also reminded you that this will be the acceptance standard in the future. If you want to avoid trouble in the future, then follow this standard in advance, so that everyone can avoid subsequent trouble!"
Ji Donglai came up with his own plan and pushed it directly to Yu Yang and Tan Xiumei.
The two people hurriedly took it in their hands and looked at it. Whether it was the text plan or the drawing and equipment plan, Ji Donglai was very detailed. Yu Yang was really convinced this time. In terms of professionalism, Ji Donglai was not inferior to anyone at all.
But when he saw Ji Donglai's quotation plan, Yu Yang's pupils dilated slightly.
"This 700,000 yuan set...Boss Ji, is this a bit much? You see, brothers can't make much money per set. You
Say yes? "
Each set of cushioning materials costs 700,000 yuan. This price makes Yu Yang feel a little sad. Tan Xiumei looked at Ji Donglai's design drawings and clicked her tongue at this time.
"Mr. Yu, you have to pay for the design fee! I can't get the money. Someone is holding the patent. It will cost a lot this time! There will be various things during the trial production. I don't say that Mr. Tan must understand that the trial production If it doesn’t work out, I will bear the danger!”
"When I lower the price of your Caofeidian set, the cost of trial production will be reduced. And let's talk about reality. Mr. Yu, this price is the market price. It will also be this price for other dumper manufacturers in the future, not just you!"
"Taking a step back, your brother will definitely make a lot of money this time. Don't miss this little money. With this acceptance test, you will be able to succeed in the next set! If the car is not inspected here, your equipment will still be good. Want to sell?"
"Do you know how much coal comes in and out of Caofeidian Port in a day? Don't lose the big for the small!"
Ji Donglai was a little worried about this quote, after all, it was a bit high. But this is a new trick, and Ji Donglai must grasp it. According to past experience, once his own products are made, manufacturers will soon imitate them.
Domestic manufacturers are now very capable of imitating. Ji Donglai must seize the opportunity before finding anyone to imitate, otherwise there will be no room for price reduction in the future.
"Okay, how much do you plan to charge for Mr. Ji's renovation?"
Although Yu Yang was unwilling to do so, he still said that money is not earned by one person.
In other words, Yu Yang was unsure. According to the design standards, this set of dumpers could almost be considered shoddy. It was important to get the project payment as soon as possible. Even if the balance was not required, the money would be in his pocket. .
Once you are stuck here, more and more things will be revealed. In this era, there is nothing more secure than having money in your pocket.
"The renovation cost is 200,000 yuan. This is the cost price. I won't ask you for more. I made money from you last time, so this time it's a gift! In addition, you need people on site. We can't just do it ourselves. All the procedures I want your people to follow you and see if our money is profitable. After we finish the construction, we must make a one-time payment!"
"This time we guarantee that you will pass the car inspection. This is the premise. If I can't get the car inspection procedures, I won't ask you for money. At that time, please don't hold back our money, Mr. Yu!"
Ji Donglai didn't talk nonsense after the things were settled. After all, he made money by relying on physical goods, not blackmailing people.
