The Rise of Heavy Industry 1980

Because the improvement plan of the CC20-3 gearbox has not yet been completed, Wang Chaoyang and Zhang Miaomiao must rush back to Changhai Agricultural Machinery overnight to continue their work.

Taking advantage of the time on the way, Wang Chaoyang and Zhang Miaomiao introduced the principle of shot peening equipment in detail.

The existence of internal stress is the biggest problem affecting the quality of castings, and the release rate of internal stress in castings can be greatly improved through high-frequency and high-speed impact of fine particles. Shot peening technology evolved into a mature treatment method in later generations, and Wang Chaoyang was not clear about the specific parameters, such as particle diameter, injection speed, and injection frequency...... However, the current situation does not require high accuracy of parameters, so three high-power blowers can do the job.

"In this way, we can record all the parameters and strive to summarize the rules, just like we do gears. Zhang Miaomiao said.

"Clever. I've asked my dad to do the work, and he'll find someone to write it down...... But the rest of the parametric analysis has to be done by you. Wang Chaoyang said.

"No problem. Zhang Miaomiao agreed. She still enjoys the sense of accomplishment of summarizing the pattern from a lot of basic data.

Seeing Zhang Miaomiao's cheerful appearance, Wang Chaoyang couldn't help but sigh with emotion: "It's great to

have you!" The girl instantly blushed: "What do you say!"

Wang Chaoyang continued: "The processing of basic data is very time-consuming and laborious, if it weren't for your help, I wouldn't have that patience, so I said it's good to have you...... What do you think?"

Zhang Miaomiao sighed, there was an urge to pinch people, if it wasn't for the guy next to her driving, she might have done it.

It was close to four o'clock in the afternoon when I returned to Changhai Agricultural Machinery.

Wang Chaoyang asked Zhang Miaomiao to go back to the office first to continue to improve the improvement plan, while he himself went directly to see Ma Sanyuan, and went to the office of the factory director Hu Qingbin with Ma Sanyuan.

Hu Qingbin was in a meeting with others, and when he learned that Wang Chaoyang and Ma Sanyuan had come to him at the same time, he quickly ended the current meeting and called Wang Chaoyang and Ma Sanyuan into his office.

"Two, what's the matter?"

"Chaoyang, just say something!" Ma Sanyuan said.

"The improvement plan of CC20-3, Miao Miao and I have preliminarily determined the direction, Miao Miao is improving, I will report to you in advance. Wang Chaoyang said.

"So fast! Very good, very good, let's say it now!" Hu Qingbin said.

"The direction of improvement is the gearbox casing, there are three main directions: first, optimize the structure of the bearing housing, second, reduce the overall wall thickness by 0.3 mm, and third, improve the coaxiality of the bearing housing, from 0.05 to 0.03. Of course, in addition to the above three points, there are also changes in the overall structure, which I will not talk about separately. Wang Chaoyang said.

After hearing these words, Hu Qingbin and Ma Sanyuan showed shocked expressions at the same time. They obviously didn't expect Wang Chaoyang to come up with so many improvement plans in such a short period of time.

"Don't be in a hurry, say it slowly, slowly one by one!" Hu Qingbin said.

"That's good.

Wang Chaoyang separated the three improvement directions and slowly introduced. The first optimization of the structure of the bearing seat is mainly to change the traditional fillet to a variable curvature fillet, which Hu Qingbin and Ma Sanyuan knew before that Wang Chaoyang did not waste too much tongue.

The second is the reduction of wall thickness, in fact, it belongs to the collateral effect of the first article, as long as the overall strength is satisfied, then the wall thickness can be completely reduced, which can greatly reduce the cost of parts.

The third is to improve the coaxiality of the bearing housing. As soon as this topic began, Hu Qingbin and Ma Sanyuan mentioned their heads at the same time, because they knew very well that 0.05 was already the limit of the current processing capacity, and it was almost impossible to change it to 0.03. However, the explanation given by Wang Chaoyang is very simple, there is no need to change the processing method, as long as the high-quality castings of the Red Star Factory can be realized.

"Can your Red Star Factory provide castings?" Hu Qingbin said strangely.

"That's right. It is a casting after the secondary treatment, and the quality is much stronger than before the treatment. Wang Chaoyang said.

"Chaoyang ......" Ma Sanyuan frowned and said, "You kid shouldn't have said this on purpose in order to pull orders for Red Star, right? Now the casing uses the internal resources of Changhai Agricultural Machinery, which has an advantage over most of the resources outside, I don't believe that your Red Star can make more 'high-quality' castings."

"You don't have to worry about this, I have already asked my father to start preparing, and the first batch of samples will be sent over within two days, will it be over if the mule or the horse will be pulled out for a walk when the time comes?" Wang Chaoyang said with a smile.

"Chaoyang, Lao Ma and I have always believed in you, but this matter is too important, so you have to say a few more words to us. Otherwise, we won't be able to sleep!" Hu Qingbin insisted.

"Oh well.

Wang Chaoyang immediately introduced the way to eliminate the internal stress of the casting, and the situation that they were preparing to use shot peening technology. Ma Sanyuan has not heard of shot peening technology at all, so listening to Wang Chaoyang's proposal this time has a great sense of identity.

"I heard that shot peening technology is a technology that Western countries are engaged in, and if we can really get it, it will be too advantageous! In my opinion, this road can really work!" Ma Sanyuan said excitedly.

"Director Hu, what do you think?" asked Wang Chaoyang.

"I also think it's okay, wait for your sample to arrive, and arrange a trial as soon as possible!" Hu Qingbin's words can be regarded as a clapper.

After hearing this, Wang Chaoyang immediately said: "Then we have to say it in front, if the sample can work, the order for the casting of the casing will be placed on our Red Star

Factory!" "You kid is really a chicken thief!"

Hu Qingbin pointed his finger at Wang Chaoyang and said: "If it can really be done, you have to tell the shot peening technology, and I will arrange the internal resources of Changhai Agricultural Machinery to do it, which will save more money, and it will not be your turn to Hongxing Factory!"

The corners of Wang Chaoyang's mouth curled, and he said in a very firm tone: " That won't work. Miao Miao and I have spent time and effort researching so many improvement plans, you can't afford not to give any benefits!"

Hu Qingbin tugged at the corners of his mouth and said: "You kid is the 'technical consultant' of Changhai Agricultural Machinery, and these jobs are your job!".

Wang Chaoyang smiled slightly and said, "Director Hu, we must make this clear in advance." Although I am a technical consultant, Zhang Miaomiao is not. And the office door used by Zhang Miaomiao and I reads 'Hongxing Factory in Changhai Agricultural Machinery Office', which is recognized by you and Chief Engineer Ma. This shows that Zhang Miaomiao and I are cooperating with you on behalf of the Red Star Factory, and all the results produced should be shared by the Red Star Factory and Changhai Agricultural Machinery.

Hu Qingbin always felt that Wang Chaoyang was arguing with strong words, but he couldn't find a rebuttal. Especially when I heard the "Red Star Factory in Changhai Agricultural Machinery Office", my nose was crooked. I didn't pay attention to it before, but I dare to wait here!

" Old Ma, did you put up that sign?" Hu Qingbin glared at Ma Sanyuan angrily.
