Siheyuan: My Northeastern Farmhouse

Chapter 230 The blind cat bumped into a dead mouse

When Gu Weijun thought of the wind, he calculated the time, and a sense of urgency arose spontaneously!

Whether it is a four-cylinder engine or a chassis, in addition to the running test in the test workshop, it also requires a long-term road running test. Don't delay it until the end of the year, and be shelved when the activity is budding!

You must know that the development of the first off-road vehicle of our domestic Second Automobile Company in Shiyan took 8 years! Five-wheeled 24 prototype vehicles were trial-produced and road tested for 40 kilometers.

The 212 Jeep looks like the Beijing Automobile Factory completed the vehicle design and actual testing according to the needs of the army in a few months, and then immediately arranged for mass production.

But before that, there was the accumulation of 7 years of experience and data from Changan Automobile...

If the materials you take out are thrown into the trash, isn't that a waste of your hard-earned plagiarism achievements? I don’t have much reserves in total!

I can't delay it any longer, I am a genius, and geniuses are unreasonable!

After making an appointment with Jiang Wanhua to go to the courtyard house in Shichahai this Sunday, Gu Weijun turned back to his dormitory and once again devoted himself to intense drawing.

On the afternoon of Saturday, April 4, after working hard day and night, Gu Weijun finally finished the drawings of the chassis. With two big black circles under his eyes, he came to the test workshop of Shijingshan Iron and Steel Plant.

In the workshop, only Master Liang and a few apprentices are processing the 493 engine, huh? Why is it so deserted today? Haven't Qian Weichang and Wu Zhonghua arrived yet?

"Master Liang, please take a look at these two drawings of the gearbox and chassis!" Gu Weijun patted his school bag, "If you have any questions, please ask me directly. If possible, we will start processing today!"

Master Liang was so frightened that he dropped all the tools in his hand. His mouth was wide open and he couldn't close it. Who can produce design drawings so quickly? Not to mention I’ve seen it, I’ve never heard of it before!

Could this be a new design? Could it be copied from somewhere?

Master Liang didn't know, he guessed it accidentally

Master Liang also realized his embarrassment and immediately covered it up with a smile, "Well, this man is old and his hands are unsteady!"

"I'll come right away!"

Gu Weijun didn't feel anything was wrong. He thought his loud voice had surprised Master Liang. He nodded with a smile and went to the office to put away the drawings.

After a while, Master Liang came in with his two apprentices. He first picked up the side structural diagram of the gearbox and looked at it. He said softly "Hey", then picked up the drawing of the part-time four-wheel drive chassis. When he looked up again, he looked at Gu Weijun. The eyes are wrong

Master Liang was secretly ashamed. He was a villain and looked down upon others. This college student was really amazing! There really is such a genius in the world!

Whether it is the manual five-speed transmission or the structural drawings of the chassis, Master Liang has never seen them before.

As the number one person in charge of repair work in a machine shop, what types of existing jeeps and cars in the country has he not repaired?

Although I don’t have a high degree of education and I don’t know how to design, I process a lot of auto parts, and my identification ability is definitely first-rate!

Master Liang can confirm that these two brand-new gearbox and chassis drawings are newly designed! And judging from the overall beautiful structure, it should be fine!

Master Liang volunteered because he was ashamed, "Gu Gong, I have no problem with your two drawings. I will immediately lead my apprentices to make sand molds and make them according to your design requirements as soon as possible!"

"Thanks to your teacher, scientist Qian, you have developed several new cast iron materials!"

"Otherwise, the materials for the bearings and gears of this gearbox would be really difficult!"

"It's just that the machining accuracy of your design is a bit higher, including the previous engine. We have to work slowly and carefully. It will be good if we can produce one piece a week!"

Gu Weijun was shocked. He had never thought about this problem before. He thought that the slow processing speed was due to the first processing and manufacturing. Slowness was normal.

I didn't expect that when I heard Master Liang say this today, I immediately felt something was wrong. Master Liang is an eighth-level fitter. He and 4 or 5 apprentices can make one set in a week. How can other workers process it?

Gu Weijun quickly asked: "Master Liang, are the drawings I designed so difficult to process?"

"What's the difficulty?"

Master Liang smiled "hehe" and said, "Gong Gu, haven't you noticed that the machine tools in our factory are generally very old?"

"Rough machining is okay, but the required precision is higher. We have to slowly grind it, otherwise we will definitely not be able to assemble it in the end!"

"Machine tool?" Gu Weijun suddenly realized, yes, machine tools will still be stuck in future generations! Even more so at this time!

But I really can’t design the machine tool! I haven’t seen anyone explaining the structure of machine tools in my browsing of web pages and videos! What kind of machining process is there on the five-axis machine tool, and then the screen is full of awesomeness...

Moreover, the technological content required by a machine tool seems to be quite high, so I don’t dare to design it blindly!

It was obvious that Gu Weijun was in a low mood, so Master Liang comforted him, "Gu Gong, don't worry, the country will solve it!"

"You have designed such a good engine and chassis. The country will definitely coordinate a batch of machine tools and processing tools!"

"At that time, it will definitely not be a problem to process and assemble a thousand jeeps a year!"

Gu Weijun could only nod sadly and write down something in the little notebook in his heart!

After confirming that the drawings were OK, Gu Weijun followed Master Liang to make sand molds, cast them, and then machine and polish them.

It was soon time to get off work. When he heard the off-duty bell, Gu Weijun twisted his tired neck and found that it was only him, Master Liang and others in the test workshop, and no one else had come yet. Gu Weijun asked Master Liang strangely: "Master Liang, why are we the only ones this afternoon?"

Master Liang raised his knees and straightened his back. After taking off his gloves, he turned around a few times and said, "Didn't Director Liu Feng go to the countryside with his technicians? Lao Zhao went back to the machine repair shop to guide the processing of single-cylinder diesel engines." .”

"I wonder why Director Zhou didn't come today?"

"He was so anxious to replace the engine of his Jeep last Saturday?"

Gu Weijun nodded thoughtfully, "Okay, Master Liang, you can get off work first, I'll go to Secretary Huang's place!"

Gu Weijun returned to the office and washed his hands with soap, changed out of his work clothes, and went to Secretary Huang's office. When he knocked on the door and entered, Secretary Huang was talking on the phone. He tapped the sofa opposite with his pen to indicate to Gu Weijun to sit down first.

Gu Weijun took the thermos and filled Secretary Huang's teapot with water, then poured himself a cup of tea. While drinking tea, he read the newspaper and waited for Secretary Huang.

Unexpectedly, Secretary Huang spent more than 10 minutes on the phone. After Secretary Huang put down the phone, Gu Weijun asked curiously: "Uncle, I just heard you talking about metallurgical materials and technology introduction on the other end of the phone. "

"What's going on? We've been on the phone for so long!"

Secretary Huang laughed "haha" and seemed to be answering but not asking: "You are such a good boy!"

Um? Why is it still related to myself? Gu Weijun was confused!

Secretary Huang walked out of the desk and walked to the sofa with the teapot, turned to Gu Weijun, threw him a cigarette, lit it himself, and then continued to smile and said: "Director Zhou just brought it to me from the ministry. phone number."

"The ministry is currently discussing metallurgical import technology issues with the central government's new technology import team. After Director Zhou handed over the cast iron alloy formula studied by you and Qian Weichang, the ministry was very pleasantly surprised!"

“Especially after the ministry confirmed the column performance of the 2-ton hydraulic press, I was even more overjoyed!”

"Although Shanghai Heavy Equipment developed our country's first 61-ton hydraulic press in , it cannot be copied! This third-line construction still needs a hydraulic press!"

"The central government is considering introducing a 12000-ton free forging hydraulic press to Czechoslovakia? But we didn't expect that we would release such a big satellite!"

Gu Weijun was stunned and quickly refused: "Uncle, this 10,000-ton hydraulic press has nothing to do with me!"

"It was all designed and established by Teacher Qian and Mr. Li Youshan!"

Secretary Huang waved his hand and continued to smile: "Don't be anxious!"

"Don't underestimate yourself. I also heard from Scientist Qian and Li Youshan that if it weren't for your computing power, they wouldn't have completed breakthroughs in theoretical design and material properties so quickly!"

Secretary Huang gently raised one hand to signal Gu Weijun to stop talking, and continued: "Although the engine you designed has not completed the operation test and fatigue test, Director Zhou also reported the overall design drawing and performance parameters while the iron was hot!"

"Hey! Fang Yi, the leader of the new technology import team, came after hearing the news!"

“After seeing the real thing, Team Leader Fang cried with excitement!”

"We have achieved world-class results! We have saved a lot of foreign exchange for the country!"

"Dajun, you have merit!"

Gu Weijun replied shyly and modestly: "It's all the collective credit!"

Secretary Huang smiled "haha" and tapped his finger, "Why are you pretending to be in front of me?"

"By the way, Team Leader Fang asked, can you design the engine of a heavy-duty vehicle?"
