The Rise of Heavy Industry 1980

"Factory director! You can kill me!" Zheng Deju was about to cry, "First, Wang Chaoyang is not a fool, and it won't work at all to knock on the side!" Second, I am not familiar with this equipment, how can you let me knock on the side!" "

If you are embarrassed, Lao Tzu will not be embarrassed? If you can't repair this equipment, won't production be delayed?" Sun Baoquan gritted his back molars and scolded.

Although Zheng Deju was scolded, he still nodded vigorously. You are right, you are right, as long as you don't let me go to the side knock on the side, you can scold as much as you want!

The factory director and the workshop director just stood in front of the milling machine and looked at the salute, and they couldn't make up their minds for a long time, and the others stood outside, and no one dared to talk more.

The problem must be solved, and it can't be dragged on like this! Zheng Deju hesitated for a while, and finally spoke again: "Factory director, why don't you directly invite Wang Chaoyang over to have a

look!" "This milling machine is the best equipment in our factory, let the people of Red Star look at it, I'm worried about leaking secrets!" Sun Baoquan said.

"But there is no other way!"

Zheng Deju actually wanted to say that the factory director, don't you have a force in your heart, we haven't figured out this equipment ourselves, what kind of leaks are you talking about?

You are hiding here for fear of leakage, maybe others are not rare

! "Okay, invite him over! In any case, find the reason first!" Sun Baoquan finally made up his mind.

"Hmm. Zheng Deju immediately ran in the direction of Wang Chaoyang.

Wang Chaoyang and Zheng Deju then returned to the single room where the universal milling machine was located, and Zhang Miaomiao naturally came over. On the way, Wang Chaoyang asked Zheng Deju about the situation, Zheng Deju didn't know what to say, so he didn't say anything, and said that the factory director was looking for help.

After seeing Sun Baoquan, Wang Chaoyang asked: "Director Sun, what are your instructions?" Sun Baoquan

cleared his throat and said: "I have a milling machine here, which is imported from abroad, and suddenly something went wrong, we can't find the reason, I want you to help take a look."

Wang Chaoyang immediately said: "The imported milling machine should be the secret of your factory, how can I be embarrassed to look at it casually!" Sun

Baoquan suddenly blushed and said: "Red Star and Sanhe Machinery are cooperative relations, what kind of secret are you talking about! The eldest nephew is slapping me in the face

when he says this!" Wang Chaoyang smiled: "Uncle Sun said this, I can rest assured." Then let's talk about it, what is the problem?" Then

Zheng Deju introduced the situation to Wang Chaoyang, there is a batch of gear products in the factory, and a groove in the inner hole is completed by this universal milling machine. In the past, there was no problem, but today a large number of unqualified products suddenly appeared, and the failure rate was as high as 70 percent!

After listening to the introduction, Wang Chaoyang looked around the milling machine for a week and said, "Director Zheng, is there a manual for the equipment?" Zheng

Deju said: "Yes...... It's in English though.

Wang Chaoyang said: "English is also fine, bring it!" Zheng

Deju sent someone to take the manual of the equipment, and there were more than ten books opened by A4, which were pushed by a small cart.

Then in the stunned eyes of everyone, Wang Chaoyang began to look through the mountain-like books, looked at them, and finally selected two ...... In this era, there are not many people in China who can speak English, and others did not expect Wang Chaoyang to understand English.

Zhang Miaomiao is the most immune one, hehe, this guy can't just speak English!"

"Director Zheng, these two operation manuals are fine, and the others are accessories and general instructions that are not needed." Wang Chaoyang said.

"I won't tell you the truth, these Western characters, it recognizes me, I don't recognize it, you say you need it, I have to let people push it all over. Zheng Deju was a little embarrassed.

Wang Chaoyang began to read the manual, and at the same time corresponded to the actual product one by one, this process lasted nearly half an hour, everyone waited on the side, no one spoke.

Sun Baoquan's mind became complicated again, and Wang Chaoyang's current actions gave him a very tangled emotion, as if he had a martial arts secret book at home, and he couldn't learn it himself, so he could only let outsiders practice it.

"There is no problem with this device.

After inspecting the universal milling machine again, Wang Chaoyang gave such a conclusion.

"How could it be?" Sun Baoquan couldn't help but ask.

"Yes, there is no problem with the equipment, how can there be seventy percent of the products that are unqualified?" Zheng Deju couldn't help it.

Wang Chaoyang glanced at Zheng Deju and said, "Do you remember what I told you earlier?" Zheng

Deju was stunned for a moment and said, "What words?"

Wang Chaoyang said: "If there is a problem with the equipment, we must not only consider the equipment itself, but also consider the workpiece.

Zheng Deju patted his head wildly: "Oh, I remember, of course I remember, wait...... Are you saying that there is nothing wrong with this milling machine, but there is something wrong with the workpiece? But it is impossible, this milling machine is not processing wool, but semi-finished gears, and there must be no problem with the material!"

Wang Chaoyang did not answer him immediately, but picked up a workpiece casually and observed it carefully. It was a gear, the tooth shape part had been machined, and the groove of the inner hole had also been processed, but the size of the inner and rear grooves was unqualified.

After observing for a moment, Wang Chaoyang asked, "Heat treatment is before groove processing, right?"

Zheng Deju nodded.

"Is there a hardness tester? Measure the hardness of this batch of workpieces and other batches of qualified workpieces. Wang Chaoyang said.

"Yes!" Zheng Deju immediately arranged for someone to measure.

As a gear processing plant, a hardness tester is a must-have.

However, in this era, there is no digital hardness tester, but a purely handmade, special round measuring head, after a fixed force strikes, measure the depth of the marks left on the workpiece, in order to judge the surface hardness.

Just ten minutes later, the hardness measurement worker returned, holding a gear in each hand, with the pit marks on the surface of the gear.

"Factory director, Director Zheng, the surface hardness of the two gears is not the same, one is Shore 35, and the other is Shore 55

!" "So much worse!" Sun Baoquan exclaimed.

"How can it be so bad?" Zheng Deju also looked confused.

Wang Chaoyang said at this time: "If I guess correctly, there is a problem in your heat treatment link.

Sun Baoquan and Zheng Deju glanced at each other, in fact, they also thought of this. In order to find the real reason, Sun Baoquan immediately took everyone to the heat treatment workshop.

Entering the steamer-like workshop again, Zheng Deju's face was extremely hot, and he vaguely remembered that when Wang Chaoyang and Zhang Miaomiao visited the factory for the first time, he said a lot of things about how powerful the heat treatment capacity of Sanhe Machinery was.

Wang Chaoyang walked directly to the heating furnace and did not speak, but looked at it to himself. Zhang Miaomiao has always seemed to understand heat treatment, and she also watched it with Wang Chaoyang, and there were a lot of questions in her stomach, but she didn't find a chance to speak.

Sun Baoquan and Zheng Deju stood silently aside, and after a while, the factory director suddenly whispered: "Didn't you say that Wang Chaoyang doesn't understand heat treatment at all?"
