Return to the exciting era of 1999

Chapter 256 This is the Power of Technology
And Wang Lu really gave some guidance, most of which were photos.A few years ago, Wang Lu trained abroad for a long time, in General Motors, Detroit, and South America.

They all have experience in railway equipment transportation, which is very important to Ji Donglai, at least five years of detours can be avoided.

Among them, the design of two sets of forward buffer boards caught Ji Donglai's attention, which are simple and effective.

Based on the model structure given by Wang Lu and the structural plans of other companies designing related products, Ji Donglai simulated the position with CAD, and finally designed the structure of the product to be [-] long and [-], [-], and [-] wide. A few hundred and forty widths.

The overall thickness is [-] degrees, and the hardness of the rubber does not need to be too high, [-] degrees.

As for the material, Ji Donglai used the simplest industrial rubber plate material, which is also the cheapest. Considering the huge weight of the vehicle itself and the huge rubbing force of [-] tons on the surface of the buffer material, the buffer material adopts the form of gradual wear consume energy.

In fact, most of the energy of the buffer material is concentrated on the column of the carriage, as long as these points are protected, but according to the requirements of the railway vehicle inspection, the overall layout must exceed a certain proportion.

The surface is added with unloading grooves, the back plate is added with a steel skeleton, and the whole is welded to the surface of the car plate by welding connection.

As for the press beam, according to the structure of the car body, the steel plate is glued and has a trapezoidal cross section.

As for the forming mold, it is the simplest, and there is no need to use a machine tool at all. The flame directly cuts out grooves from the eighty iron plate, the surface is polished, and the bottom is connected with bolts.

In terms of molding, the cover is a [-]mm thick iron plate, and the grooves inside are connected to the surface of the bottom plate with bolts, and each time the mold is opened, it is directly jacked up by hand.

Ji Donglai opened three sets of molds alone, and three [-]-ton vulcanizing machines were integrally formed.

After the design here was completed, Ji Donglai directly assigned tasks to the rubber mixing workshop, and the mold workshop also stepped up to do the design.

As for Wang Lu, the other party gave some "guidance" opinions symbolically, Ji Donglai immediately took it back to make changes, and then made a plan for various things of the buffer material, and Teacher Wang gave "guidance" again.

In the evening, Ji Donglai had already formed all the plans into words and drawings, and only then did he arrive at the place agreed with Tan Xiumei.

"Mr. Ji, I'm sorry last time. The different management methods of our two places led to misunderstandings. Please don't mind! If there is anything wrong last time, please forgive me. I will do this first as a respect. ..."

Compared with the arrogance of the last time, this time Yu Yang was almost in a state of begging for help.

Did Ji Donglai hold it? After all, he was doing business. He didn't ask the other party to drink a fine, but he accompanied him for a drink. The other party wanted to drink. Ji Donglai stopped him directly.

"Mr. Yu, let's talk about business. Mr. Tan told me about your affairs in detail. From yesterday to today, I have been running about your affairs. This matter is not about brothers saying you, what you did is wrong! "

"Even the railway people dare to offend you. I found a relationship with the power plant yesterday, and I found a relationship outside, and then I got in touch with the other party. But this time you have to pay a lot of money. The rectification project must be Gotta do it, but something on your car needs replacing!"

"I 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's not that they make things difficult for you! You have put so much thought into this project, this time People are also teaching you a lesson!"

"However, I have also reminded that the acceptance criteria in the future will be this. If you want to avoid trouble in the future, then follow this standard in advance, so that everyone can avoid subsequent troubles!"

Ji Donglai came up with his own plan and pushed it directly to Yu Yang and Tan Xiumei.

The two hurriedly held it in their hands to check. Whether it was the written plan or the blueprinted equipment plan, Ji Donglai did it in great detail, and Yu Yang really convinced him this time. In terms of professionalism, Ji Donglai did not lose to anyone at all.

But seeing Ji Donglai's quotation plan, Yu Yang's pupils dilated slightly.

"This is a set of 70... Boss Ji, isn't that a lot? You see, brothers can't make a lot of money per set, don't you think so?"

Each set of cushioning materials costs 70 yuan. This price made Yu Yang feel a little heartbroken. Tan Xiumei also clicked her tongue when she looked at Ji Donglai's design drawings.

"Mr. Yu, you have to pay the design fee! I can't get the money. Someone has the patent. This time it will cost a lot! There will be various things during the trial production. I don't say that Mr. Tan must understand that the trial production If the time is not successful, I will bear the danger!"

"I'll lower the price of your Caofeidian set, and the cost of trial production will be reduced. Let's talk about reality, Yu Zong, this price is the market price, and it will be the same price for other dumper manufacturers in the future, not just you!"

"Take a step back and say, this time your brother has definitely made a lot of money. Don't miss this little money. With this acceptance, you will be able to succeed in the next set! There is no car inspection here, and your equipment is not good enough. Want to sell it?"

"Do you know how much coal is transported in and out of Caofeidian Port in a day? Don't lose the big because of the small!"

Ji Donglai was also a little apprehensive about this offer, it was a bit high after all.But this is a new trick, and Ji Donglai must grasp it. According to past experience, if his own products are made, manufacturers will imitate them soon.

Now domestic manufacturers are too capable of imitating. Before finding someone to imitate, Ji Donglai must seize it, otherwise there will be no room for price reduction in the future.

"Okay, how do you plan to charge the cost of the general renovation?"

Although Yu Yang was unwilling, he still said that money is not earned by one person.

In other words, Yu Yang had no idea. According to the design standards, this set of dumpers could almost be regarded as shoddy. He got the project payment as soon as possible.

Once stuck here, more and more things will be revealed. In this era, there is nothing more reassuring than keeping money in your pocket.

"The renovation cost is 20 yuan. This is the cost price. I won't ask you any more. I earned your money last time. This time it's a gift! In addition, you need to come to the site. We can't just do it ourselves. Various procedures need to be done." Your people will follow suit to see if our money is good or not, we have to settle the payment once we finish the construction!"

"This time we will guarantee you to pass the car inspection. This is the premise. I won't ask you for money if you don't get the car inspection procedures. At that time, please don't delay our money!"

When things are settled, Ji Donglai doesn't talk nonsense, after all, he relies on real things to make money, not blackmail people.
