"Director Cheng, do you have any comments and suggestions?"

Hearing this, Cheng Facai only felt bitter in his mouth. Pen, fun, and www.biquge.info

In the course of this year, there are very few things that the research institute can get its hands on, such as tractors, which are already stereotyped products, and almost do not need to be improved, and the others are really not mentioned.

"Commander, for some time now, the main work of the Chengtang Institute is to develop a new type of diesel engine, and now some progress has been made, and it will take some time to finalize it. The imitation of the Jaguar VII gasoline engine has also encountered difficulties, and we have not yet understood the aluminum casting process. No matter what you try, the problem of oil spills will not be solved. ”

Whether it is strengthening the seal or grinding the parts, there are still problems with those imitation gasoline engines, and the most torturous thing is the oil leakage.

The imitation team also worked hard, and the machine also leaked oil several times. But as soon as it started, it kept flowing. Without solving this problem, there can be no basic security, let alone anything else.

Qin Lang asked:

"Have you found the root cause of the problem?"

Engines weren't that easy to build in the first place, and even in this era, they still look a little crude. But there are already a lot of processes that need to be used, which is not something that can be solved by local methods.

Cheng Facai said dejectedly:

"We haven't found a specific reason yet, and we also produce strictly according to the drawings, and even the materials used are recycled from scrapped machines, so there is no material problem. The precision casting process is more stringent than the original factory, and the cylinder block is carefully inspected by several eighth-level technicians, and the original factory is not different in the slightest. With the original parts, you can toss as much as you want. ”

There is no problem with the cylinder block, but it is not possible to install the self-produced parts. This has been repeated dozens of times, and some people have become depressed. Just say that the technology and equipment are backward, and you don't want to make qualified products in this life.

Hearing this, Qin Lang suddenly remembered the complaint of the Soviet engineer.

"Whether it's the pressure of the press is not enough, or the accuracy of the die is not accurate, causing subtle differences in the parts. If this is the case, infiltration is inevitable! ”

Cheng Facai was stunned for a moment, and there will definitely be no problem with the accuracy of the mold. Because these are those eighth-level technicians, the special steel billets are processed and formed little by little on precision machine tools.

But the issue of the stamping machine was really not considered. Thinking of this, he took out two parts from a bag in his hand, one was original and the other was made by Zhangye. After putting the two originals together and comparing them carefully, I found a lot of problems.

The right angle of the original factory is the right angle, and the right angle made by Zhang Ye has a small arc, which makes the whole part more "meaty".

"A little difference can eventually become a big problem, I see!"

Cheng Facai roared excitedly.

Zhangye's existing hydraulic press is a small machine purchased from the United States, which is enough to produce ordinary parts, but not enough for parts such as engines.

After Qin Lang waved his hand, he said in a deep voice:

"Comrade Gu Xinan is still in Germany, let them inspect it, and import a large hydraulic press as long as conditions permit. But I have a little doubt, Zhangye has a lot of equipment, and the performance of some machine tools is even leading in the world. Why can't you make some machines out of them? The principle of the hydraulic press, everyone here is clear, can we make some? ”

At that moment, a young man raised his hand.

"Commander Qin, can I do relevant research?"

Lu Jinbo, who was sitting next to him, whispered:

"Commander Qin, his name is Shen Hong, a progressive young man recruited from Shanghai, who has been working in a hardware store, and is now a technical team leader in the automobile department of Chengtang. During this time, I was researching materials in the library, and I was a diligent learner! ”

Qin Lang's eyes lit up all of a sudden, he didn't expect that the left net and the right net really caught a big fish.

He is quite familiar with the person in front of him, because there is a 10,000-ton hydraulic press where the old man works, and its maker is the one in front of him. It is said that just looking at the appearance of foreign hydraulic presses, I turned around and made the owner of the 10,000-ton hydraulic press, you must know that Huaxia in that year could not even take out the 3,000-ton one.

"Okay, since Team Leader Shen has such ambitions, this project will be handed over to you to be responsible, how to organize, who you need to report as soon as possible, money, materials, I will try my best to satisfy. But I would like to ask, in terms of the facilities in the red zone, how much pressure do you think we can build? ”

Shen Hong stood up and said:

"Commander, the existing equipment can produce about 800 tons of pressure, and it will not be used in the first year, and the other is that there is still a gap in the process, if there is any mistake, it will definitely be a big accident!"

Qin Lang smiled:

"It's good if you have this understanding, I'll see you decouple from the car! The 800-ton hydraulic press is built first, and then the 1,000-ton hydraulic press is not used now, which does not mean that it will not be used in the future, and the technical reserve is necessary. There are also aluminum and steel rolling, we are also a blank, since Team Leader Shen recommended himself, I will hand it over to you for research. Don't rush to produce results, we still have time. ”

"Ahh

Shen Hong was stunned for a moment.

Happiness came too suddenly! In the past, when I was in Shanghai, I had to ask for help everywhere when I read technical books. When I came to Zhangye, I found that the library here is a treasure trove of knowledge. I just had some experience, but I was entrusted with a heavy responsibility. For a moment, he was so excited that he didn't know what to say.

After a while, he trembled his lips and said:

"Commander, I ......, I will definitely complete the task."

Qin Lang smiled, and then said in a deep voice:

"Comrades, we are now a blank slate. As you can see, it is either American or British, and even a small Czech Republic is ahead of us. As a Chinese, I feel aggrieved. Once China was the pinnacle of the world, but now it has fallen into such a field, why? Since the Opium War, China has lost wars every day, and it is still losing, why?

It's not that we are not as good as others! Fight with foreign guns and cannons with big blades, how many lives does it take to fill it? At present, more than 10,000 people have been filled in the Fengtian front, and more will be filled in once the weather improves. Why is the sacrifice so great? Because we are dealing with a highly industrialized country!

Comrades, what are you going to draw on this blank piece of paper in front of you? Splendid rivers and mountains, or thousands of cliffs? I hope it's the splendid rivers and mountains, because the cliffs have been overcome by us! ”

"Wow!"

As soon as the words fell, the venue burst into fierce applause, and for a moment everyone stood up and shouted:

"Splendid rivers and mountains, splendid rivers and mountains!"
