"How is it, can Guoyang be repaired" Ning Xiaohong couldn't help but ask.
Zhao Guoyang turned his head and glanced at Ning Xiaohong and said, "Please don't doubt my professionalism, Comrade Xiaohong." ” "The oil pump seal of this die-casting machine is broken, just replace it with a new one, and this robot should have sent you some when it was supplied.
It's just that it's been so long, I'm afraid you have already thrown it away, and it would have been possible to use a domestic sealing ring, but in terms of service life."
"Hmph, don't underestimate people" Ning Xiaohong glanced at Zhao Guoyang and said, "You wait, I'll go get it."
After a while, Ning Xiaohong came over with two brand-new sealing rings, raised his arm and waved.
"Yo, yes, it's still there" Zhao Guoyang took it and took a look, and it was really the original goods.
With the seal, the problem is solved.
Zhao Guoyang finally checked the pressure proportional valve coil, and after finding that there were no other omissions, he gently pressed the "start" button.
The buzzing machine immediately let out a roar and was running steadily.
Zhao Guoyang looked at it and exclaimed: "Tsk, I have to say that the quality of things in this island country is really good, after a few years, not only can it be used as usual, but the noise is so small." ” "This is really fixed" Ning Xiaohong opened her mouth wide, a little incredulous.
"It's not going to break again in a while."
"You crow's mouth" Zhao Guoyang glanced at Ning Xiaohong and said, "Can you say something nice, this thing is related to my business plan."
"Oh, the big plan for entrepreneurship, what a big plan" Ning Xiaohong tilted her head and asked with interest.
"Hehe, the secret of heaven must not be leaked."
Zhao Guoyang smiled mysteriously and said, things haven't been done yet, so he naturally won't publicize it everywhere.
"Cut, don't say pull down, who is rare."
Ning Xiaohong didn't get the answer she wanted, so she couldn't help pouting.
Seeing this, Zhao Guoyang couldn't help but smile and said: "Why, turning your face is faster than turning a book, it's good to pull, if I can succeed in starting a business, I will definitely give you a surprise." ” "Then, this is what you said, you are not allowed to rely on the skin when the time comes" Ning Xiaohong immediately smiled after hearing this.
Zhao Guoyang puffed up his chest and said loudly: "The husband has a word, and the horse is difficult to chase" Looking at the vigorous and handsome face of the young man in front of her, Ning Xiaohong suddenly felt that there was a group of deer jumping around in her heart, and two red clouds appeared on her face.
Zhao Guoyang followed the conversation and asked, "Don't you need this equipment in the factory now?"
Ning Xiaohong came back to her senses and nodded subconsciously: "Well, we now have that big die-casting machine, this one can't be used at all, otherwise it won't be idle for so long." ” After getting the letter, Zhao Guoyang suddenly made up his mind and said: "That relationship is good, I will see Director Liao later, and I will just talk about the loan." ” Ning Xiaohong said "um" and said, "If you open your mouth to borrow it, Master will definitely agree." ” While the two were chatting here, the bell had already rang over there.
Hearing the bell, Zhao Guoyang hurriedly said to Ning Xiaohong: "I'll talk about borrowing the die-casting machine later, I'll go and weld the frame first." ” When Zhao Guoyang and Ning Xiaohong trotted to the side of the laser welding machine, Director Liao had already been waiting there, chatting with Hua Guosheng about something.
Seeing Zhao Guoyang and Ning Xiaohong coming, Liao Jingsheng said with a little teasing: "Xiaohong, the time you have been chatting with Section Chief Zhao is a bit long, and you have left these guests of Hongda Machinery Factory behind."
Ning Xiaohong secretly glanced at Zhao Guoyang, both ears were red.
However, this girl is a little pepper temper after all, and she quickly found a point to fight back: "Master, don't take such a burying person, Section Chief Zhao and I just went to get down to business." ” "Serious business, what serious business" Director Liao couldn't help but ask.
"That imported die-casting machine, do you remember, just now Section Chief Zhao helped us repair it" Hearing this, Liao Jingsheng was stunned, he knew that his apprentice had never spoken, since he said so, it must be true.
So Liao Jingsheng hurriedly held Zhao Guoyang's hand and said, "Section Chief Zhao, thank you very much." ” Zhao Guoyang humbled a few words again and again, and wanted to propose the matter of leasing the die-casting machine, but after looking at Hua Guosheng, Xu Dongfeng, and Zhang Chaoyang who were watching from the side, he still held back first.
The rotary laser welder was ready, and Zhao Guoyang asked Hua Guosheng and the three of them to lift the frame over, put it in place, and then prepare to weld it by themselves.
Seeing that Zhao Guoyang was about to make a move, Liao Jingsheng and Ning Xiaohong glanced at each other, and there were some five or six points in their hearts.
Although I heard Zhao Guoyang himself say that he knew how to operate a laser welder, the two had not seen it with their own eyes after all, and it was normal for them to be a little apprehensive.
Ning Xiaohong is better, after all, when Zhao Guoyang repaired the die-casting machine just now, he had already demonstrated his professional level, in her opinion, even the advanced die-casting machine in the island country can be repaired, and it should not be difficult to operate this laser welding machine.
Liao Jingsheng was not as confident as Ning Xiaohong, and when he saw that Zhao Guoyang had already walked to the laser welding machine, he couldn't help but speak: "That, Section Chief Zhao, why don't you talk to Xiaohong about the requirements and let her operate it." ” Zhao Guoyang turned around and explained: "Director Liao, our frame is a little special, and the spine needs some special treatment, and it is difficult to explain clearly.
As for the welding of other parts, you can trouble Section Chief Ning for a while. ” Zhao Guoyang understood Liao Jingsheng's worries, and added: "You don't have to worry, I am very familiar with the operation of the laser welding machine." ” Laser spot welding machine, in the early eighties, has been widely used in Western developed countries.
In this regard, although the republic started relatively late, it had gradually become popular in the late eighties, so Zhao Guoyang said that he would operate, and Liao Jingsheng believed it a little.
The laser welder is mainly composed of laser, power control, coolant, light guide and focusing, and binocular stereo microscopic observation.
In appearance, it has a compact structure and small size; In terms of positioning, the microscopic coordinate indication coaxial with the laser beam does not require special fixtures; In terms of control, laser power, pulse frequency, and pulse width can all be preset and changed through the control panel.
In addition, there is no need to fill solder, the welding speed is fast, the contact is reliable, the workpiece deformation is small, and the molding is beautiful, which is also what distinguishes it from the traditional welding machine.
The working principle of the laser spot welding machine is actually not complicated.
It is the use of high-energy laser pulses to heat the material in a small area, and the laser radiation energy diffuses to the inside of the material through heat conduction, melting the material to form a specific molten pool, which belongs to melt welding
