The salary of the entire 754 factory is less than 100,000 yuan per month, and their R&D funds are directly consumed by two million in half a year, or in half a year. Chen Xiangwei dared not continue with such a responsibility. New Chinese iqi.

Even Zheng Hao was a little confused.

Just like a useless person, keep doing it. I don’t know when it will be successful. It’s like a bottomless pit, I don’t know how much it will need to be filled in. If I don’t do it, the previous investment will be wasted, which is not a good thing for the entire base.

Finally, after discussing with Chen Xiangwei and the leaders of Factory 754, I felt that it was most appropriate to throw this matter to Director Liu. After all, the mechanical processing capabilities in the Ninth Hospital are unquestionable.

The Ninth Academy can’t do it, and there are few units in the entire country’s military system that can do it.

While understanding the situation, Liu Yijiu followed him into the production workshop.

The production of Dawu crucibles does not require too much equipment. The raw materials are all responsible for the production of blue tungsten to pure tungsten powder. When loading powder, a steel core mold is used to position it, and then a thick layer of rubber is made on the outside, and the outer ring is fixed with a steel ring. In this way, there is a very wide gap between the steel core and the outer steel sleeve. When loading powder, workers must always pay attention to the distance between the steel core and the steel sleeve, otherwise the crucible blank will be thick and thin at the same time.

There is no big problem with the deviation of three or two millimeters. After isostatic pressure, the powder blank will be processed. At that time, the steel core will be positioned, and the wall thickness of the processed powder blank will become even.

Demolding is the most likely thing to have problems.

There are four evenly distributed pull rings under the steel core. After the powder blank is processed, it is suspended by driving with a wire rope. Then, under human operation, it slowly rises and reaches a certain height. From manpower, the steel core of the workpiece, which is more than one meter high and weighs more than one ton, slowly rotates the entire strip steel core by 180° by gravity and manual force, and finally relies on the weight of the powder blank itself and the draft angle inside. Slowly raise the steel core mold in the middle to separate the blank and the steel core mold.

In this process, relying on manpower to control the flip, one person is in the center to schedule. Four people must cooperate well to master the position of the four rings. The entire powder blank with mold is located at the top because the center of gravity is located at the top, because the density of tungsten is more than twice that of steel! The weight of the entire large dock crucible is concentrated on the solid top.

If you are not careful, the center of gravity will deviate too quickly during the human turn due to incoordination. At that time, the entire powder blank will fall off. Scrapping of the workpiece is a small matter, and injuring the person is the most difficult thing to solve.

Liu Yijiu really wanted to use mechanical power to flip, but at this time, designing special equipment is not a simple matter, and manpower is the most suitable.

"Director Liu. The previous process is not a problem. It is mainly when using heavy horizontal lathes to process the outer circle..." Entering the open machining workshop, a heavy lathe that looks a bit short, thick and heavy was quietly held in a corner of the workshop. This heavy horizontal lathe was originally just a C61125 imported heavy horizontal lathe in the Soviet Union, with a rotating diameter of 1125 mm. In theory, it can process rotating parts with a diameter of 1.125 meters.

The height of the entire machine tool is flush with the ground, and the bed is buried directly underground. Even so, the distance from the top of the chuck to the ground is much higher than that of a person.

Although the diameter of the large tungsten crucible is only more than 700, when clamping the outer circle, ordinary claws will not have any effect because they are too short. They must process and lengthen the claws by themselves. This will expand the rotation diameter of the entire workpiece to about 1.5 meters.

"Your inner hole is not processed!" Liu Yijiu frowned when he saw the silver-white large tungsten crucible next to the lathe.

Didn’t it mean that the inner hole has been processed?

"Director Liu, the inner hole is indeed not processed. Since the deformation amount during sintering cannot be controlled, and the wall thickness from the bottom to the top of the crucible is different, the deformation amount is also different, so..." Chen Xiangwei said embarrassedly.

There is no problem with machining the inner hole. That's just theoretical.

After all, the four jaws clamp the outer circle are far more stressed than only five points, and they are at the position where the force is at the mouth wall and the center of the bottom. In the end, the weight of hundreds of kilograms is all at the mouth wall and at the center.

"Director Liu, I think this is impossible to process like this at all. The process is wrong. Only using a stand-alone cart is suitable!" Liu Yijiu was about to speak, and a forty-year-old turning worker who was originally standing next to him shook his head and said.

This is the best worker in the 754 Factory, Yue Lin.

As a seventh-level turning worker, although he has not reached the top eight level of the driving worker, his technical strength is so strong that he can stand out in many people in the entire seventh-five-four factory. Sometimes he is in good condition for organizing skills with other brother units.

If it weren't for the lack of business that the factories had declined, they might have become the top eight-level workers in the turning industry.

Liu Yijiu turned his head and looked at Yue Lin. He still knew the top technical forces in the factory.

"Use a car? Can you tell me how to solve the weight of hundreds of kilograms when the bottom and the mouth are not flat? What is the problem of correcting it? Leaning to lower the point?" Zheng Hao said coldly before Liu Yijiu could speak.

These words surprised Liu Yijiu.

When did this guy Zheng Hao understand such profound technical problems?

However, from Zheng Hao's face, he did not see a trace of pride, but instead felt a little cold. He seemed to have a lot of complaints about Yue Lin, a senior technical worker?

This is strange.

"Can the sleeper car be solved now? Once it is installed, it has cracked due to gravity before it is corrected. A crucible of more than 400,000 yuan, and no one can stand such a great pressure. It is a consumable piece in itself. Anyway, I can't do it. If you have the ability, you come..." Yue Lin curled his lips and said to Zheng Hao with contempt.

When Liu Yijiu heard this, his brows frowned.

This should not be said by a senior driving worker at all. Skills are one aspect, and psychological quality is even more important.

Moreover, this guy is still a thorny person. Not to mention that he has not reached the top level eight-level turning worker, he has reached the top level. Do you think he is invincible in the world?

"Master Yue, it's wrong for you to say this. When you encounter a problem, we should find a way to solve it. Since I proposed this process, it must be my reason. Now the lathe has been changed, and it is obviously not possible to process such parts in a vertical car. Although the gravity becomes vertical, the gravity is on the top. Once the lathe rotates, the huge centrifugal force will make the workpiece fly out and hit people..." Liu Yijiu did not get angry.

"What's the reason for you? I just thought it would be enough to learn some theory in books? If so, senior workers at Level 7 and Level 8 will not be everywhere? If you think it's possible, why don't you come and I'll study next to you?" Yue Lin didn't take Liu Yijiu, the young director who climbed up with the background seriously at all.

I am the top big shot in this factory and I can’t even get it. Who can? If I don’t give myself a level 8 worker, everything will be free of negotiation!

Liu Yijiu was furious when he heard this.

I have long heard that these senior technical workers are all very arrogant, and he thinks this is normal.

Masters are all achieved through practice.

Moreover, technical workers have a proud capital. Two bombs and one satellite are all produced by hand by hand to produce some high-precision parts. Such high-level technical workers should instinctively be respected!

But this guy in front of me seems to be the same.

"Xiao Yue, let's solve the problem in front of us first. As long as we solve it, the matter of the eighth-level worker is easy to talk about." Chen Xiangwei's face looked very ugly, but he smiled apologized. It's okay for them to do theory, but in fact they can't do it, so they have to accommodate these big shots.

"What's going on?" Liu Yijiu immediately asked Chen Xiangwei.

It is not without technical workers' discussions on conditions with the organization when researching technical problems. But it should not happen at this time.

For his own selfish desires, he caused the company to lose more than one million in vain!

And his salary is only more than one hundred!

How can you not be angry?

When he knew the details, this guy had to become a Level 8 worker in the past. He had very strict control over the top job titles. Yue Lin's technical level was a bit reluctant to even Level 6. In the past, many high-precision parts of the maintenance equipment in the entire factory had to rely on him to do, which helped him to increase his mentality.

When the critical moment comes, you will threaten the factory.

"Since that's the case, you don't have to do this anymore. Lao Wang, call the base immediately and transfer two eighth-level turning workers and a ninth-level fitter to come over." Liu Yijiu said gritting his teeth when he heard this.

He really has no good feelings for someone like Yue Lin.

Don’t you think your skills are awesome?

When Yue Lin heard Liu Yijiu's words, he disagreed. The eighth-level turning worker is not a cabbage, and he can find it just by looking for it.

"Director Liu, is this a bit inappropriate?" Chen Xiangwei looked at Yue Lin with a complicated expression.

Yue Lin, a young man, has a very good talent, but he is not very good at being a human being. He never expected that Liu Yijiu would mobilize senior technical workers from the base with a helicopter.

"There is nothing wrong, Lao Zheng, tell them that I will wait for them here, and let Yu Jianguo come with me." Although Liu Yijiu knew about the technology, he thought it would be better to let Yu Jianguo and the others solve this problem. It would be good to propose it casually at that time.

ps: Today is Hulu’s wife’s birthday, and I decided to go out for a long time with her and update a chapter first.

In addition, a VIP reader group was established last night, and several rich leaders smashed red envelopes. Hulu didn't want to build such a group, but among the ordinary readers, last night, the leader Yang Ysl and Tianhai Xiangyun went crazy and smashed hundreds of red envelopes. How many genuine supporters got it, Hulu won't say much more.

They wanted the brothers to support Hulu’s genuine version. What was the result? I can’t say. Later, the discussion came up with this VIP group. The rich leader would send red envelopes from time to time. Brothers who have all subscribed please take a screenshot of the fan value of this book and the starting point id to join the group.
