The Rise of Heavy Industry 1980

Wang Song personally went to send samples to Changhai Agricultural Machinery, which took two days. The circumference was reduced from 15 mm to 12 mm, which is by no means something that Changhai Agricultural Machinery can easily agree to.

This shaft is used in the gearbox of an agricultural tractor, which plays a very important role, once the whole gearbox fails, the whole gearbox will be paralyzed, so Changhai Agricultural Machinery needs full verification to make a decision. There are 6 items to be verified, and in addition to the mechanical assembly relationship, there is also a verification of strength.

In

order to verify the stiffness of the shaft, the shaft was loaded into a 15-tonnage hydraulic press, and the huge hydraulic equipment formed a sharp contrast with the slender shaft, and Wang Song's heart was even more suspended.

Wang Song can't understand the values displayed on the dial, but he still knows that the larger the value, the greater the pressure, the small shaft is clamped in the center of the huge workbench, like a bone in the mouth of the steel giant crocodile, with the hydraulic supercharger making a "snort" sound, the big mouth of the giant crocodile began to close, and the shaft that was bitten in the middle made a slight "squeak" sound, Wang Song only felt that his throat was a little tight, and he scolded himself in his heart

The new shaft has proven to have withstood the test of steel giants, and other validation projects have also passed without a hitch. Liu Qingyi, who was traveling with him, patted Wang Song on the shoulder and said, "Are you okay, old man?"

"It's okay, it's okay!" Wang Song said with a long sigh of relief, his whole back was cold, as if he had been wet with sweat.

"It's okay, let's go back to the office and talk about it!" Liu Qingyi said.

Not long after the report ended, a man in his sixties wearing reading glasses rushed into Liu Qingyi's office, took the experimental report without saying a word, looked at it carefully for ten minutes, and then looked up with a very solemn expression on his face.

"The axle diameter has really been reduced to 12 mm? It's really good! Your name is Wang Song, please forgive me for my gaffe, my name is Ma Sanyuan, I am the chief engineer of this tractor gearbox, you have reduced the axle diameter to 12 mm, it really helped me a lot!" The old engineer named Ma Sanyuan looked very excited, and held Wang Song's hand when he spoke.

"What the hell is going on?" Wang Song was confused.

"Don't be in a hurry, tell me how you came up with the idea of reducing the shaft diameter, and what the detailed design process is, all of which must be told me, which is very important to me!" Ma Sanyuan became more and more excited.

"This ......" Wang Song was embarrassed, the drawings of the new shaft were given to him by Zhang Miaomiao, and he began to prepare the sample before he had time to ask in detail, and he couldn't answer Ma Sanyuan's question at all.

Seeing that Wang Song couldn't answer, Ma Sanyuan had no intention of giving up. Since the designer of the new axle has someone else, then make a special trip

to the Red Star! With Ma Sanyuan's identity, it is a matter of one sentence to want to meet the people of the subordinate suppliers, but the 12mm new axle is too critical, he can't wait, and directly asked Liu Qingyi to arrange the car, and immediately go to the Red Star Factory together!

Wang Song took the Hongqi sedan for the first time, and his entire back was wrapped in the sofa, and the adobe road was bumpy and he sat in it steadily, not to mention how comfortable it felt.

I heard that this Hongqi car is the same as the chairman of the National Day ceremony to review the troops, and there is only one agricultural machinery in the entire Changhai, which was used only when the provincial leaders came, but this time because Ma Sanyuan was in a hurry, so the above was specially approved.

However, compared with the stable Hongqi car, Wang Song's mood is a little up and down.

The matter of the 12-millimeter new shaft, judging by the reaction of Liu Qingyi and Ma Sanyuan, should be a matter of eight or nine and ten, but Ma Sanyuan is so anxious to rush to the Red Star Factory, what do he want to ask?

What worries Wang Song even more is that the processing method of the new shaft is not mature, and this sample is made by Liu Degui with his hard work

The Hongqi car finally stopped at the gate of the Red Star Factory, Wang Song took Liu Qingyi and Ma Sanyuan to go inside, and wanted to go to the office to rest, but Ma Sanyuan said that he wanted to see the designer of the new shaft for the first time, Wang Song had no choice but to lead the way towards Zhang Miaomiao's office.

When he arrived at Zhang Miaomiao's office, he found that there was no one, Wang Song guessed that Zhang Miaomiao was in the workshop, so he took the two leaders of Changhai Agricultural Machinery to the workshop.

When I came to the door of the workshop, I saw Zhang Miaomiao explaining things to several masters in the maintenance class, still holding a thick stack of drawings in his hand, and Wang Chaoyang was also on the side. What made Wang Song angry was that Wang Chaoyang was dozing off on the cover of the lathe motor, and he didn't know what was going on with this kid, he loved to sleep so much recently!

Outsiders were not allowed to enter the workshop, Wang Song stood at the door and shouted "Xiao Zhang", Zhang Miaomiao immediately rushed over when he heard the sound, and did not forget to pull the drowsy Wang Chaoyang before leaving.

After meeting, Ma Sanyuan showed a surprised expression when he found that the designer of the new shaft was a little girl, thinking that it was an old engineer of the same age as himself......

Zhang Miaomiao answered them one by one, very fluently, and when she talked about the fourth strength theory, she deliberately added additional explanations.

Although Zhang Miaomiao didn't understand the fourth strength theory originally, she understood it very thoroughly after using it once...... There is no way, who made Wang Chaoyang a "handicap party", except for putting forward theories, the detailed calculations were all done

by Zhang Miaomiao! Listening to Zhang Miaomiao's answer, the expressions of the other four people in the office were different.

Ma Sanyuan's expression was solemn with a bit of excitement, especially when he heard the fourth strength theory, he took out his notebook and recorded it carefully while listening.

Liu Qingyi is engaged in the management of Changhai Agricultural Machinery and does not know much about technology, but his face is still full of consternation, because he has never seen the old engineer Ma Sanyuan like this.

Wang Song's expression was the one that changed the most, and he was a little panicked at the beginning, as if he was worried about whether Zhang Miaomiao could answer Ma Sanyuan's question, and after seeing Zhang Miaomiao's ability to answer, he finally put his heart back into his stomach. But then he began to have fire in his eyes and his nostrils dilated, because he saw Wang Chaoyang!

Wang Chaoyang didn't seem to know what kind of occasion this was, so he actually fell asleep against the wall!

If it weren't for the presence of outsiders, Wang Song would have rushed over to give Wang Chaoyang a shudder.
