Chapter 041 He Turned Out to be an Expert?
Before Peng Huading said thank you, Wang Lu said again: "That set of gears from French VOROU is a lot of troublesome. It is not enough to meet the requirements only when the size and related technical parameters meet the requirements. It must meet the requirements in terms of mechanical properties and service life. The samples must be submitted to France and given to them for strict tests before they will place an order for you. They can guarantee that their orders will not be less than 200 sets. By the way, their unit price is very high, each set is as high as 15,000 yuan.
Our company has found several machinery companies to try production, but all failed because of the unqualified mechanical performance indicators. Now our company has basically given up this order. If you can make it, you can sign an import and export contract with the French company directly, or through our agency. We only charge 10% of the handling fee, including round-trip transportation costs."
After hearing her words, Peng Huading was very moved: a pair of hydraulic pump gears costs more than 120 yuan, and this set of French gears is more than 100 times that of it. It’s such a fat sheep!
Seeing his expression, Wang Lu pursed his lips and smiled and said, "The orders for hydraulic gears are long-term. If your product is of good quality and delivery is timely, you will have a stable channel for making money. In the future, I can persuade the leader to transfer the orders given to you.... You don't have to hurry now. You should slowly find a manufacturer that can help you process. After you make money, you will resign from Huakang Company to set up your own company. Not only will you take all this order, but you can also slowly take on other orders. The processing of that set of French gears is much more difficult, and even if you work hard, you may not be able to do it. I advise you not to put too much thought on the set of French gears. Although the profit is high, the risk is greater."
As she said that, she smiled self-deprecatingly and asked, "Do you think I'm nagging?"
Peng Huading hurriedly said, "No, I'm grateful, it's too late."
Wang Lu gave him a blank look and said, "It's good to know..., open them and see them. If you have any questions, you can ask me now. If I can answer them, I can ask our company's experts if I can't answer them."
Peng Huading bent down and picked up the paper box from the ground and placed it on the coffee table. Then he tore off the self-adhesive stickers and took out an oil paper bag from it. When he opened it, he saw that it was a gear slightly larger than the slap.
He took it into his hand and took a look, and he couldn't help but exclaim.
Wang Lu asked, "What's wrong?"
Peng Huading said: "Why do French guys want such high-precision naked-based gears?"
Wang Lu was stunned and asked, "What kind of naked base gear? Why haven't I heard of this word? What does naked base mean?"
Peng Huading asked back guiltily: "Have you ever heard of the word naked base? It means that the gear teeth of the gear are composed of the same metal or alloy from the inside out."
Wang Lu thought for a moment, shook her head in confusion, and then said, "No, I have never heard of it... Besides, the gears are like this now. Do you use several metals or alloys for a gear? Don't fool me. I am not an amateur. I studied engineering in college. I have been doing business for many years and often come into contact with gears. Although I am not an expert in gear, the average technician in the factory may not be as good as mine."
Peng Huading's heart skipped a beat: It turns out that the word "that has not become popular in the industry yet, but he said it in advance.
This cannot be blamed for him, because he had no knowledge of gears before, did not know the current terminology and technical level in the field of electromechanical science and could only speak with future knowledge, and did not notice whether the word "naked base" exists in reality.
While he reminded himself that he would read more technical books in the field of electromechanical and electrical fields in the future, and tried not to say "outsiders" words, he explained: "I mean, why is there no layer of alloy added on the surface of the gear teeth? I heard from my teacher that applying alloys to the surfaces of moving parts such as gears, bearings, shafts is the latest technology in the world. Since French people require high-end gears, they should consider using this technology."
After explaining it randomly to himself, he held the gear and said, "The pressure angle of this gear is only thirteen.5 degrees, which means that the bending strength and contact strength required for the gear meshing are not large. However, the tooth width coefficient is greater than the normal value, which means that the load is very large. The selection of the two parameters is contradictory, and they even go to extremes. The material is 42 chromium manganese alloy gear steel, which has high creep strength and long-lasting strength at high temperatures..."
At the beginning, especially when Peng Huading said the word "naked base", she thought he was pretending and didn't understand the gear at all, and at most he had a slight understanding. But as he told the gear, she was shocked: "Just look at it, you can know its parameters and characteristics? It's hard for ordinary experts to do it, right? Didn't he learn computer applications? Can he reach such a high level by self-study, which is far better than me, an engineering graduate, or even our company's experts?"
At this time, Peng Huading said: "If these parameters of the gear are carefully selected by the designer and the choice is made entirely based on the actual working environment of the gear in the future, then the gear is absolutely unqualified. Not only is the hardness of the gear teeth insufficient, but the yield strength is not enough.
Even if the manufacturer performs scientific heat treatment on the gear before leaving the factory, the internal microscope is fully refined, the martensite and austenite are distributed appropriately, and the hardness and yield strength are qualified, but due to the high working environment temperature of the gear, the relevant technical indicators will gradually deteriorate, resulting in the gear being unable to work for a long time, and it will have to be replaced after working for about 300 hours."
Wang Lu's eyes widened and she blurted out: "Have you seen our test report and the conclusions of the French manufacturer before?"
Peng Huading asked back: "How is that possible?"
Wang Lu said: "Then how do you know that the inspections of these gears meet the standards before going abroad? How do you know that this gear can only work less than 300 hours? It's so amazing!"
Peng Huading smiled and said, "I said I have this ability, do you believe it?"
Wang Lu was full of confidence in Peng Huading at this time, and quickly pointed to the cardboard box and said, "Take out the technical drawings and information inside, and see if you can make qualified gears?"
Peng Huading took out the technical drawings and technical parameters corresponding to the gears in his hand from it, looked at them carefully, and thought to himself: No wonder they were designed strangely. It turned out that they took this stupid method to solve the harsh environmental conditions.
In an instant, he had seven or eight ways to process and produce gears that meet the requirements, but he did not say it immediately because he was worried that the methods he had thought of might not be taken into action. It is very likely that there would be no corresponding processing equipment in this era, and there would be no corresponding materials on the market. Even if the words said it would leak their secrets because of their forward ideas, just as Wang Lu was surprised just now.
He thought for a moment and said to Wang Lu: "It's hard!"
Wang Lu didn't expect Peng Huading to lie? She said: "Of course it's difficult. If it were easy, the processing manufacturer would not be found in this order yet?..., you saw so many problems just now, so I must have some idea, right?"
Peng Huading smiled and said, "I don't have many ideas, but I know that if I follow the processing method and heat treatment method of the gear in my hand, I will be able to waste as much as I do."
Wang Lu didn't believe that he had no choice but to say, "I don't secretly learn your skills, so there is no need to keep it so confidential, right? Give me a truth, are you sure?"
Peng Huading said: "Even if I have a way, I can't do it."
Wang Lu's eyes lit up and she said, "I can ask the manufacturer who has made this gear to pay you or your teacher to guide them and ask them to do it. You will charge a technical guidance fee."
