"Ha ha…"
Seeing this scene, Xu Zhenming smiled and looked at Meng Haisheng who was sitting nearby.
Meng Haisheng understood the instructions: "Xiao Wang! Open the PPT file of the investigation of Wannan Electric Machinery Plant!"
The meeting format of Yiming Group is the most advanced in China. All meetings will use PPT files to show what they want to report, which is intuitive and saves everyone's time.
Before long, Xiao Wang, who was in charge of operating the laptop, opened the PPT file and projected the file on the wall.
"Everyone! This wooden mold for winding coils should have been developed by me at the beginning of 80 years! You are still using it now. Is it accurate?" At this time, Meng Haisheng asked everyone with a serious expression.
"It should be fine! Is there an error in the coil data?"
Everyone shook their heads and looked at their colleagues around blankly.
At this time, Xiao Wang turned to the next page.
This page is a picture of a wooden mold being measured.
In the photo, it is obvious that the long axis of the ellipse of the wooden mold has become shorter by 4 mm.
"What does it matter if the difference is 4 mm?"
"Nonsense, the coil is 4 mm away, and the electromagnetic field has changed!"
"Oh? It turns out that there is still this kind of error! No wonder the performance of our motors goes up and down!"
There is no need for Meng Haisheng to explain, the engineers here already know the result.
They are all blushing with embarrassed expressions.
"The big boss is right, we are indeed a bit responsible! But this is a problem with the production department, what does it have to do with our technical department?" At this time, some people were actually secretly convinced.
However, Meng Haisheng said at this time: "This rotor dynamic balance test device should be designed by you later to test electric fan rotors!"
"Yes! This rotor was invented by Lao Wang!"
"Hehe... It's the method everyone thought of together, not my old Wang alone!"
"Is there a problem with this rotor dynamic balance test device?"
Everyone looked at the screen curiously.
According to Meng Haisheng's instructions, Xiao Wang switched to the next pattern.
This pattern is a small video.
An optical axis is being tested in the video.
There are marks on the optical axis, and a bar is drawn with a black marker.Every time the optical axis stops rotating, the mark stays at the top.Logically, there should be a problem with this optical axis, and the center of gravity is not in the center.
But when it was tested on another dynamic balance test device, the mark changed another position, and it was at the bottom every time.
From this point of view, both dynamic balancing devices have problems!
No problem with the dynamic balance device, the normal shaft workpiece under test can be stopped at any position.
"Oh! The precision of these two dynamic balance test devices cannot meet the requirements!"
"Impossible, I arrange the production of all the accessories in accordance with the process and technical requirements of the drawings!"
"Our quality inspection department has all checked, and the tolerances of the accessories are within the technical requirements of the drawings!"
After discovering this problem, the engineers in the technical department, production department and quality inspection department pinched themselves.
"Everyone, be quiet! It's not terrible to find the problem. It's terrible that I dare not face my mistakes! Both of these dynamic balance test devices have problems. Why didn't you find out? Or did you find that you don't want to change it? Big problem!"
Seeing the noise in the conference room, Xu Zhenming tapped the conference table with his fingers to calm everyone down.The question he raised was not a technical question, but a question of attitude.
The problem of insufficient technical reserves in product research and development is not terrible. The terrible thing is that there is no correct attitude to research and development.It is impossible to make a good new product like that.
When everyone saw the big boss saying this, they were silent.The gaze looking at Xu Zhenming became cautious.People like them have real fear at this time, not as arrogant as they were just now.
"Xiao Wang opened the structural diagram of the dynamic balancing device!"
At this time, Meng Haisheng ordered again.
Xiao Wang clicked the mouse to turn the page, and then displayed a group of photos on the wall projection.
I saw that the dynamic balance device was disassembled, and someone pointed out the obvious unreasonable part of the mechanism by hand.
Meng Haisheng said in conjunction with the photo explanation: "This transmission mechanism is unreasonable, and this bonding mechanism is unreasonable. How can this pin be installed like this... How did you consider it when designing?"
Experts will know if there is any as soon as they reach out!
After his explanation, the engineers from the original technical department of Wannan Electric Machinery Factory bowed their heads.Lao Wang blushed even more, took a cup of water to drink, and covered his face.
At the same time, a group of photos are displayed on the screen.
This group of photos is the dynamic balance test device of the servo motor of Yiming Group.
"Colleagues! This is a CNC dynamic balance test bench developed by our Yiming Group, which can collect data and automatically generate test curves. The first screen shows the data curve of Sanlin variable frequency motors, and the second one is The curve test chart of our Yiming Group Company!"
"The two pairs are almost the same. In other words, the performance of the rotor system of our Yiming Group's variable frequency motor is similar to that of Sanlin Motor! Excuse me, can the rotor system of our Wannan Motor Factory reach this level?"
Meng Haisheng no longer looked at the big screen at this time, but glanced sharply, looking at his former colleagues.
He has been appointed by Xu Zhenming as the director of Wannan Electric Machinery Factory. Today, he is using these data and photos to sound the alarm to his former colleagues, so as not to cock their tails and make management difficult.
"Oh... the performance of our company's products is actually comparable to that of the Japanese company's products?"
"No wonder Meng Lao is so arrogant after coming back!"
"Haha... I will definitely have a future in Yiming Group!"
The engineers and technicians who came to the meeting did not speak at this time, but the meaning in their eyes was very complicated.In a word, they now recognize the form.
Seeing this scene, Meng Haisheng didn't say anything, but looked at Xu Zhenming: "Mr. Xu! My speech is over!"
"Colleagues! The purpose of our meeting today is not to criticize the meeting, and not to catch some people's mistakes and mistakes. It is to make everyone unify and prepare for the next transformation of the inverter motor production line!"
"The frequency conversion motor is a high-tech product, and few factories in China can manufacture it. The transformation of this production line is very important, and you must not take it lightly! The following is the manager of Duan to introduce the detailed plan!"
Xu Zhenming first appeased these newly hired engineers and technicians, and knocked by the way.Only then did Duan Meisheng preside over the meeting on the technical transformation of the variable frequency motor production line.
Duan Meisheng has returned home.
In the past, he was not reused in Wannan Electric Machinery Plant, and his colleagues had no room for improvement.Even if I work in Sanlin Company, although I have earned a little more money and my status is not high, I am still looked down upon.Otherwise, his lover will not force him to return to his hometown to work.
Now, as the head of technology at the headquarters of Yiming Group, he has returned to Wannan Electrical Machinery Factory, which immediately blinded many people.Looking at his former colleague, he took a deep breath to calm his mood, and then said:
"Colleagues! The main body of the variable frequency motor is divided into three parts, one is the cast steel shell, the other is the coil assembly, and the third is the rotor assembly system. I arranged these three parts in this way."
First, two qualified suppliers for cast steel shells should be developed in Jiujiang City.Steel casting manufacturers must adopt precision casting technology.Before these two suppliers can produce qualified products, our factory must use machining technology to ensure the accuracy of the motor housing.
At this time, someone asked: "Director Duan, what about the original cupola in our factory?"
The cupola is one of the main equipment of the foundry, which can be used to smelt pig iron.Wannan Electric Machinery Factory originally had a casting workshop, which used the most primitive wooden mold casting process.Even the resin sand molding technology has not been adopted and can be eliminated.
Thinking of this, Duan Meisheng took a look at Xu Zhenming and said: "My personal opinion is to ban the foundry, and refurbish the cupola, shot blasting machine, molding equipment, etc. of the foundry of Wannan Electric Machinery Factory!"
Xu Zhenming knew what he meant: Duan Meisheng wanted to get my authorized Shangfang sword.
He then smiled and said: "Haha...I agree with the opinion of Director Duan. In addition to the equipment that can be used in Wannan Electric Plant, all other equipment will be dismantled and shipped back to the company headquarters. Of course, this opinion is that Director Duan has the final say. . He represents me!"
Hearing Xu Zhenming's words, everyone looked at Duan Meisheng with different gazes: "Damn! Duan Meisheng turned around and was actually spotted by billionaire Xu Zong. His days when he was so prosperous are just around the corner!"
Some people regret it at this time: "I regret so much. I have satirized Duan Meisheng before! He, he won't wear shoes for me?"
In the eyes of everyone admiring, Duan Meisheng got Xu Zhenming's authorization on the spot, and his heart was naturally warm: "I can only retire from Yiming Group in this life! The boss is so cool, how can he be a man after he quit? Let's talk about it. After quitting, can the new boss be so happy?"
So he put away his thoughts and began to arrange the production process of the second main accessory of the inverter motor: "The coil assembly system of the inverter motor. Our original enameled wire, winding device, mold, etc., are all removed. But those works The station must stay!"
"Director Duan, those workbenches are all very heavy cast iron parts, why should you stay?" Everyone asked puzzled.
At this time, Meng Haisheng interjected with a grin and explained: "Those workbenches were available when I first entered the factory. The longer the cast iron parts are used, the smaller the internal stress and the more stable the performance."
"Oh..." The people suddenly realized.
At this time, Duan Meisheng began to arrange the production process of the rotor system.
In the rotor system, active processes such as casting, machining, heat treatment, and mechanical assembly are involved.Duan Meisheng has solicited Xu Zhenming's opinion and is also preparing to set up a temporary constant temperature workshop in Wannan Electric Machine Factory, but the quality of the workers must be improved.
"Everyone! Regarding the production process of the rotor system, I will start a class in this conference room and give you three days of training. Then I will select key personnel from you to go to the company headquarters for training!"
Thinking of this, Duan Meisheng said with a serious expression.
"Huh? I have to go through training?"
"I'm a senior engineer! Need training? It's a big laugh!"
At this time, the engineers who were focusing on recording all showed surprised eyes.
"Ha ha…"
Seeing this scene, Xu Zhenming smiled and looked at Meng Haisheng who was sitting nearby.
Meng Haisheng understood the instructions: "Xiao Wang! Open the PPT file of the investigation of Wannan Electric Machinery Plant!"
