Chapter 59

"Look, boss, all the parts have been made according to the requirements of the design drawing!" in a small workshop of Daqian food factory, several people in work clothes surrounded Jia Yapeng, while Jia Yapeng sat on a workbench and looked at the various parts scattered on the desktop.

"Ha ha, I haven't played this thing for at least ten years. It's really memorable to see it!" Jia Yapeng sighed when he looked at the familiar and strange parts of the table in front of him

"Oh! Boss, have you played 4WD since you were more than 10 years old?" an old man over 50 years old said with some doubts, "but no, 4WD was invented in Fusang in 83. Where did you play 4WD ten years ago? Is it the R & D version of Tiangong?"

"Ha ha, I'm just kidding!" Jia Yapeng laughed. He said that ten years ago was another world. At that time, he was only 15 years old.

"Come and see if the assembly level of my competition level is still there!" Jia Yapeng smiled, and the expected chassis instantly appeared in Jia Yapeng's hands, followed by gear, rotating shaft, motor, motor cover, guide wheel, gasket, rubber guide ring, phoenix tail, switch, axle, wheel hub, exposed tire, and finally car cover and spray buckle.

In less than five minutes, a complete 4WD was assembled in Jia Yapeng's hands.

"My God..." seeing the speed, the staff of the bank who made the model car were stunned.

Although the model car was made by hand step by step, and each part was polished by them, it could not be assembled by them without more than ten minutes.

As a result, it took Jia Yapeng more than 4 minutes to assemble a 4WD successfully. This is a miracle. Has Jia Yapeng assembled a 4WD countless times?

"Don't be surprised. In fact, there are very systematic 4WD competitions in Fusang. One competition item is 4WD assembly, which is who can assemble a standard 4WD at the fastest speed!"

"I haven't assembled a 4WD car for a long time, and the speed is much slower. When I reached the peak, I could assemble a 4WD car in about three minutes. The record of Fusang was created by a player in 2009... 89. People successfully assembled a complete 4WD car in only 1 minute and 02 seconds, including pasting stickers on the car Cover the time! "

"So put away your shocked expression, otherwise if you see those record holders in the future, you will lose your chin!" Jia Yapeng laughed, and the staff laughed.

"Come on, let me have a try. How fast is the 4WD!" Jia Yapeng turned the switch, a loud engine roared, and the four wheels of the 4WD began to rotate at a very fast speed.

"This motor doesn't work!" Jia Yapeng shook his head after listening to the sound. "The number of coil materials of the motor is too small. If the motor speed can't go up, it should be wrapped at least about one third more!"

"There is also a problem with the bite degree between gears. The noise is too loud. Such gears will break up in a short time!"

"Wait... How does it smell like burning? Did I forget to apply lubricating oil just now? Or did you not provide lubricating oil at all?"

"This won't work. In the future, a small tube of lubricating oil must be put into the product, and the bite of each gear must be coated with lubricating oil, otherwise the service life of the car won't be long!"

“……”

In less than ten seconds, Jia Yapeng pointed out more than a dozen defects in one breath by simply listening to the sound and smell, which made these staff both ashamed and shocked.

I'm ashamed of how many defects there are in the infallible experimental products, and the shock is how familiar my boss is with 4WD cars, which is so much more powerful than my R & D personnel. It's amazing!

"You forget, the drawings and design drafts of the 4WD were originally drawn by our boss. Our boss is the best 4WD master in China. Naturally, you can't compare the boss's ability!" the old man scolded.

"Come on, Lao Li, I'm a little embarrassed when you blow. I just used to play more!" Jia Yapeng laughed. "By the way, is there a track? Run and see this car!"

"Yes, I'm ready!" Lao Li took Jia Yapeng to an open space, on which a winding circular track has been set.

"How dare you use iron plate to build the track?" Jia Yapeng exclaimed when he saw the material of the track.

"No way, we also know that the plastic track is cheaper, but the mold of the plastic track is more troublesome. We can't make it in a short time, so we temporarily welded one with an iron plate!" Lao Li explained.

"Yes, it's my first time to race on the tin track, hahaha!" Jia Yapeng laughed and put the car on it. The car immediately began to run wildly on the track.

"We did it! We did it!" seeing the car running so happily, the staff around cheered. You know, they have worked for about three months to make this small 4WD. It's really hard.

But the cheers of these staff did not last for a few minutes, and the car suddenly stopped on the track.

"What's the matter? Is there no electricity?"

"It's impossible. The two No. 5 batteries can run for at least half an hour! It's only a few minutes. How can they run out of electricity!" the people were stiff. A staff member immediately went up and took the 4WD car into his hand. After repeated inspection, he couldn't see why.

"No problem, it's on the metal copper plate of the switch!" boss Jia shook his head. "Obviously, the copper plate of the switch you use is not tough and elastic enough, and the bending radian is not large enough. Over time, coupled with the impact of the track, it will lead to poor contact at the switch and natural power failure!"

"This is very important. You must find a way to adjust it for me to ensure that the copper strip at the switch can maintain elasticity for at least one month, otherwise our reputation will be ruined!"

"Really, it's really that the copper plate at the switch is in bad contact!" hearing boss Jia's words, the inspection staff fluctuated the copper plate a little, and the car galloped again.

"Boss! You are so awesome!" this time, all the staff looked at Jia Yapeng like a God. How familiar his boss was with 4WD, so he didn't even touch it and found out the problem!

"Cut, I didn't know how many times I was dented by this switch copper when I was playing 4WD!" Jia Yapeng shook his head and remembered the story when he first played 4WD.

At that time, the quality of 4WD cars, especially domestic 4WD cars, was very poor. The problem mainly focused on the copper switch. It was good at the beginning, but it won't take long to play, there will be insufficient elasticity, and then all kinds of power cuts.

At first, Jia Yapeng didn't understand so many problems. He thought the battery or motor was broken. I don't know how many batteries were damaged and how many 4WD cars were replaced. Later, he learned from his little partners who also participated in the competition that it was a problem of switch copper.

Those racing level 4-drive cars need to be assembled by buying race level switch copper in a special Tiangong store. Otherwise, if the 4WD car stops because of a sudden power failure during the race, it will lose!

In a few seconds, you can be left behind by several laps.

These experiences are all the experiences Jia Yapeng gave in his last life!
