Super military empire

The monthly salary of the entire 754 factory is less than 100,000 yuan, and their research and development funds are directly spent in half a year, or two million yuan in half a year. Such a responsibility, Chen Xiangwei dare not continue. .

Even Zheng Hao is a bit tangled.

Just like a chicken rib, just keep doing it. I don't know when it will be successful. It's like a bottomless pit. I don't know how much to fill in.If you don't do it, the previous investment will be in vain, which is not a good thing for the entire base.

Finally, after discussing with Chen Xiangwei and the leaders of the 754 factory, it is most appropriate to leave this matter to Director Liu. After all, the machining capabilities of the Ninth Institute are beyond doubt.

The Ninth Institute cannot do it, and there are not a few units in the country’s military industry system that can do it.

While understanding the situation, Liu Yijiu walked into the production workshop.

The production of Dawu crucible does not require too much equipment.The raw materials from blue tungsten to pure tungsten powder are produced by themselves. When the powder is loaded, a steel core mold is used for positioning, and then a layer of thick rubber is made on the outside, and the outermost is fixed with a steel ring. There is a wide gap between the core and the outer steel sleeve. When loading the powder, workers must always pay attention to the distance between the steel core and the steel sleeve, otherwise the loaded crucible blank will be thick on one side and thin on the other. .

The deviation of three or two millimeters is not a big problem, and the powder will be processed after isostatic pressing.When the steel core is used for positioning, the wall thickness of the processed powder will become uniform.

Demoulding, this is one of the most problematic things.

There are four evenly distributed pull rings under the steel core. After the powder billet is processed, it is hung by a steel wire rope on a crane, and then slowly rises to a certain height under the operation of a human. How tall, the steel core of the workpiece weighing more than one ton slowly rotates the entire steel core of the mold by 180° by gravity and artificial force, and finally depends on the weight of the powder body and the internal draft angle, slowly Let the steel core mold in the middle rise to separate the blank and the steel core mold.

In this process, relying on manpower to control the flip, one person in the middle of the dispatch, four people grasp the position of the four rings, which must be well coordinated. Because the center of gravity of the whole moulded compact is at the top, because the density of tungsten is two times that of steel. More than twice!The weight of the entire large dock crucible is concentrated on the top of the solid.

A little carelessness will cause the center of gravity to deviate too quickly and fall directly during the process of manpower flipping due to uncoordinated coordination. At that time, the entire powder body will fall. The scrapping of the workpiece is a small matter, and it is the most important thing to hurt the talent. Things that are difficult to solve.

Liu Yijiu wanted to use mechanical power to turn it over, but at this time, designing special equipment is not a simple matter. Manpower is the most suitable.

"Director Liu, the previous process is not a problem, mainly when using a heavy-duty horizontal lathe to process the outer circle..." Entering the empty machining workshop, a heavy-duty lathe that looked a little stubby and heavy was held quietly. In a corner of the workshop, this heavy-duty horizontal lathe was originally just a c61125 heavy-duty horizontal lathe imported from the Soviet Union, with a rotating diameter of 1125 mm, and theoretically capable of processing rotating parts with a diameter of 1.125 meters.

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

Although the diameter of the large tungsten crucible is only more than 700, it is clamped when machining the outer circle. The ordinary jaws will not have any effect because they are too short. You must machine the extended jaws yourself.In this way, the rotation diameter of the entire workpiece is expanded to about 1.5 meters.

"You haven't processed the inner hole!" Liu Yijiu frowned when he saw the large silver-white 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. Because the amount of deformation during sintering cannot be controlled, and the wall thickness of the crucible is different from the bottom to the top, the amount of deformation is also different, so..." Chen Xiangwei said embarrassedly .

There is no problem in processing the inner hole, it is only theoretical.

After all, the four jaws clamp the outer circle, which is far more forceful than only five points, and it is still at the position of the mouth wall and the bottom center. In the end, the weight of hundreds of kilograms is all at the mouth wall and the center position. Two points above.

"Director Liu, I don't think this can be processed like this at all. The craftsmanship is wrong. It is only suitable for processing with a vertical lathe!" Liu Yijiu was about to speak, and there was a forty person standing next to him. The year-old turner shook his head and said.

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

As a level 7 lathe worker, although he did not reach the top level 8 of the lathe job category, his technical prowess, in the entire 754 factory, can be proud of many people. Sometimes he competes with other brothers in organizational skills. It is well maintained.

If it were not for the lack of business and the decline of various factories, perhaps they would have become the top eight-level lathe workers.

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

"Using a vertical car? Can you tell me how to solve the weight of hundreds of kilograms when the bottom and the mouth wall are not flat? What about the alignment problem? Lean on the cushion?" Liu Yijiu returned Zheng Hao said coldly when he was not talking.

These words surprised Liu Yijiu.

When did Zheng Hao understand such advanced technical problems?

However, from Zheng Hao's face, he didn't see a trace of despair, but a trace of coldness. He seemed to have a lot of complaints about Yue Lin, a senior skilled worker?

This is strange.

"Can the sleeping car be solved now? As soon as it was installed, it cracked due to gravity problems before it was calibrated. A crucible is more than 400,000 yuan. Anyone can't stand such a great pressure in their psychology. It is a vulnerable part itself. You can't do it, if you have the ability, you come..." Yue Lin curled his lips and said to Zheng Hao with contempt.

Liu Yijiu frowned when he heard this.

This should not have been said by a senior lathe worker. Skills are one aspect, and psychological quality is even more important.

Moreover, this guy is still a thorny head, not to mention that he has not reached the top eight-level turner, but at the top, does he think he is invincible in the world?

"Master Yue, you are wrong to say that. When we encounter a problem, we should find a way to solve it. Since I proposed this process, there must be my reason. Now the lathe has been changed, and the vertical turning process of this kind of parts Obviously it won't work. Although gravity becomes vertical, it is at the top. Once the lathe rotates, the huge centrifugal force makes it easier for the workpiece to fly out and hit people..." Liu Yijiu did not get angry.

"What's the point for you? I just thought it would be fine to learn some theory from books? If so, senior workers of level 7 and 8 are not available everywhere? If you think it is possible, or you come, I will study next to you? "Yue Lin now doesn't take Liu Yijiu, the young director who climbed up with his background, seriously.

I am the top player in this factory, and I can't even win it. Who can?If you don't give yourself an eighth-level worker, everything is forbidden!

Liu Yijiu was angry when he heard this.

He had long heard that these high-level technical workers were all bullish, and he thought this was normal.

The masters are all developed by training.

Moreover, skilled workers have arrogant capital.Two bombs and one star, but some high-precision parts are produced by hand.Such senior skilled workers should instinctively be respected!

But this guy in front of him doesn't seem to be such a thing.

"Xiaoyue, let's solve the immediate problem first. As long as it is solved, the eighth-level worker's affairs are easy to talk about." Chen Xiangwei's face is very ugly, but his face is full of smiles. These people, there is no problem in theory, but in fact they can't operate. , Have to accommodate these big takers.

"What's the matter?" Liu Yijiu immediately asked Chen Xiangwei.

Skilled workers talk to the organization about conditions when they are working on technical problems. This is not impossible, but they should not appear at this time.

He caused the company to lose more than one million yuan for his own selfish desires!

And his salary is no more than one hundred!

How can I not be angry?

After knowing the details, this guy was making a fuss about becoming an eighth-level worker in the past. The top job titles are controlled very strictly. Yue Lin's technical level is a bit reluctant even for the sixth-level. In the past, many high-precision parts of the equipment for maintenance in the entire factory had to rely on him, which helped to increase his mentality.

When it's critical, it must be inside the factory.

"In this case, you don't have to do this. Pharaoh, immediately call the base and transfer two eighth-level lathes and one ninth-level fitter over." Liu Yijiu gritted his teeth when he heard this.

For people like Yue Lin, he really doesn't have any good feelings.

Don't you think you have great skills?

Hearing what Liu Yijiu said, Yue Lin disagreed. The eighth-level lathe worker is not a Chinese cabbage. You can find it if you want to.

"Director Liu, isn't this inappropriate?" Chen Xiangwei looked at Yue Lin, who was still holding his head in a complicated expression.

The young man Yue Lin had a very good talent, but he was not that good.He never expected that Liu Yijiu would mobilize high-level technical workers from the base by helicopter.

"There is nothing inappropriate, Lao Zheng, tell them, I will wait for them here, and let Yu Jianguo follow along." Although Liu Yijiu knows the technology, he thinks it is better to let Yu Jianguo and the others solve this. It's also good to suggest it by yourself at that time.
