Eight hundred and seventieth chapters true ability
"This is a bearing billet with a radius of two centimeters. The error must be within two millimeters...Chen Tong, you were the first place in the Fucheng Turning Competition last year. Come on, show me a finished car!"
Chen Wei pointed at one of the more than thirty workers in front of him and shouted.
The worker named Chen Tong was around 27 or 27 years old, about the same age as Chen Wei. He confidently walked to a lathe, put on his protective gear skillfully, and started working on the machine.
More than ten minutes later, a bearing was pulled out.
"Teacher Chen, I'm done!"
"Okay, Song Peng, please test it!"
"Teacher Chen, the error of this part is 1.5 millimeters, which meets the 10% standard!"
Others looked envious when they heard this value. They are all lathes. It is already good to achieve the specified error of 10%. The other party improved it by 0.5 millimeters. This is the level of a master. Don't underestimate this.
The improvement is enough to affect the life span of a machine tool, which is amazing.
"You all come here and watch me work. Remember, you must write down my techniques in detail!"
After Chen Wei finished speaking, he put on his protective gear and walked to the same machine tool to start working.
Everyone watched intently. Chen Wei's technique was very different, but his speed was much faster. A finished product was completed in less than five minutes.
"Test it!"
Chen Wei pointed.
"What? The error is only 0.8 millimeters? How is it possible?"
This value frightened everyone. You must know that these equipments are the original equipment of the bearing factory and have been used for almost 30 years. This kind of equipment is used to make bearings in Fucheng. Over the years, no one has been able to
By reducing the error to less than 5%, such a part completely complies with the manufacturing standards of the new generation of equipment. In other words, if the bearing factory can produce bearings with this precision, then it will not go out of business and will not go out of business.
It will not be acquired by Liu Lang in the form of a special enterprise.
Now Chen Wei has done it. If he was a master with decades of experience, everyone would still accept it, but he is younger than many people. Is it just because he is a top student of Huaxia Industrial Technology?
"Are you surprised? Why can I make the same device with high accuracy? Do you know the reason?"
Chen Wei asked.
"Teacher Chen, because you are a college student! You are also a top student of Huaxia University, we can't compare!"
One person shook his head and answered.
"What's wrong with college students? College students are human beings too, with one head and two hands. Do I have one more hand than you? That's three hands. The police will arrest me!"
"Three Hands" is what the common people call the thief. Everyone laughed when they heard it. Although the thief was a college student, he was also very "rude" when he was working. Everyone felt that he was their "kind".
"Let me tell you, this is craftsmanship. What is craftsmanship? To put it bluntly, it is your own ability. This ability allows you to bring out the limits of the machine. Do you want to have such ability?"
"I think about it, of course I think about it, even in my dreams!"
everyone shouted.
"Okay, then you have to study hard. In fact, it is very simple. It is a kind of tangent craft, and this craft was invented by Mr. Liu Lang Liu!"
"What? Mr. Liu again?"
Everyone was shocked again, but they quickly recovered. Since they came to work at Norinco, almost all the knowledge they learned every day was related to Liu Lang, not to mention Chen Wei, who was the kid in Professor Xiong's mouth.
He is also an omnipotent god.
"Okay, everyone, don't be stunned. Today I will tell you the essence of tangent technology. You must learn it hard. If you can't learn it well, then give me fifty bearings for my car today...!"
In another workshop, an engineer from Huaxia Industrial Technology Co., Ltd. named Du Xin was giving lessons to a group of welders.
"Let me ask you a question. I use the same material to make two doors. One of them is smaller because it is made of a whole piece of material. The other door is made of two pieces of material welded together. Then I
I just asked, which of the two doors is stronger?"
"Teacher Du, of course it's the first door!"
one person asked.
"What do you think?"
Du Xin smiled and looked at the others.
"That's right! It should be the first one!"
"I know your reasons. I think the integrity of a complete piece of material is certainly better than that of welded material. It's like sewing clothes. If the clothes are broken, no matter how good you sew them, they can't be compared with the original good clothes...
However, I tell you that this idea is wrong. The real welding technology is not splicing, but a way to improve the original strength. If you don’t believe it, I will demonstrate it to you today...!"
"This is a metal material strength tester that Mr. Liu bought from the United States. It can test various indicators such as stress, tensile strength, and toughness of pipes. There are two kinds of pipe fittings here. One is a pipe forged by a thousand-ton hydraulic press.
, the diameter is thirty centimeters, let’s take a look!”
Everyone took a look. As welders, of course they could tell whether the pipes had been welded or not. This was the most common type of iron pipe that was fifty centimeters long and thirty centimeters in diameter.
"These are two identical iron pipes, but I'm going to weld them together now, you watch!"
After Du Xin finished speaking, he put on the protective gear, picked up the welding tools, and started working. This action immediately attracted everyone's attention.
They are all workers with several years of welding experience. Although they are not experts, there are also long-established "experts" among the masters, such as "the number one welder in the pressure vessel factory" and the "old welding king in the hydraulic parts factory".
The skills of these old workers are definitely unique, but compared to Du Xin, who is only thirty years old, they seem to be a little inferior. They have all kinds of difficult welding methods at their fingertips.
Du Xin's various welding techniques, such as overhead welding, direct welding, and twist welding, dazzled everyone with various techniques. In less than ten minutes, two iron pipes were welded together.
"What a speed!"
Everyone was secretly amazed.
This kind of iron pipe is the most common cast iron, and the iron pipe is not big, but if you had to weld it yourself, it would take fifteen minutes.
Although everyone has not yet understood what Teacher Du's purpose is, with this method, I am afraid that no other person will be found in Fucheng.
"Okay, now we are going to do a destructive experiment, which is to tear this iron pipe apart, and then let's see what everyone thinks. Xiao Sun, come and help me!"
Two people put a 70-centimeter-long iron pipe into the metal material measuring instrument, then sealed it completely. After turning on the switch, everyone retreated to the digital display screen aside.
Various numbers were constantly displayed on the screen, and Du Xin explained them to everyone.
"This is the pressure, this is the pressure endured by the internal pipe, and the pressure limit of the pipe... Look, the iron pipe is almost at its pressure limit!"
In just ten minutes, there was a "bang" sound in the pressure chamber. The sound was very small, but everyone could hear it clearly. It was obviously that the iron pipe had been burst by the hydraulic oil.
Of course, these people had encountered this phenomenon in their respective factories. The pressure of the hydraulic press was too high or the welding was not handled properly. The iron pipes sometimes looked like pieces of paper under the powerful hydraulic press. They were all surprised.
However, they have never seen or even heard of this instrument that can display various parameters. It is simply a magical instrument.
