Siheyuan Great Craftsmen

And if he remembered correctly, our country's first coal mining machine was the Donbas-53 combined coal mining machine, which was copied from its big brother in 1.

With a clear idea in his mind, Zhou Tian naturally had a clear idea and quickly started drawing on the blueprint. As time passed, the shape and parameters of the coal mining machine equipment gradually appeared on the blueprint.

In a blink of an eye, a month has passed.

For a month, Zhou Tian continued to immerse himself in the research of transistor production lines in the mornings, and continued to draw blueprints of coal mining machinery and equipment in the afternoons.

Ten days ago, with his hard work, he finally developed a complete transistor production line. After instructing the workshop to start manufacturing, he threw himself into the design drawings of coal mining machinery without thinking twice.

Finally, on this day, when Zhou Tian put down the last stroke and looked at the stack of mechanical drawings in front of him, he breathed a sigh of relief and rubbed his sore wrist.

This month can be said to be the busiest period for him since the establishment of the machinery factory. He even forgot about the birthday party he had promised to celebrate with his second brother.

Fortunately, his wife Shen Yulin reminded him, so he gave his second brother an unforgettable birthday that night. Otherwise, he might have felt guilty for a while. Now, the design of the coal mining equipment has finally been completed.

Next are the automobile production lines and military production lines.

Zhou Tian actually already had a plan in mind for the automobile production line, so it wouldn't be difficult to complete it now. However, the military production line left him a little confused. After all, he had not developed many military products.

And this should not fall within the scope of their research institute, but no matter how he thought about it, he still felt that he seemed to have taken on a big trouble, but things have come to this point, he can only do his best.

He let out a breath, leaned back in his chair, took out a cigarette from his pocket, lit it, and exhaled a deep puff of smoke.

He had forgotten how long it had been since he had been so relaxed. Now, with the intake of nicotine, his whole mind began to relax all of a sudden.

He smoked a cigarette, then stubbed it out in the ashtray and shouted outside, "Xiao Liu!"

"Dean, you're looking for me!"

Liu Yuan heard Zhou Tian's call outside and immediately stood up and walked in.

"Xiao Liu, go call Jiang Long and the others!"

"Okay, Dean!"

After hearing what Zhou Tian said, Liu Yuan retreated.

Until half an hour later,

"Dean, have the designs for the coal mining equipment been completed?"

Before he entered the office, Jiang Long's voice rushed in with anxiety, and Zheng Tianhua and Chang Weijun behind him also looked at Zhou Tian with a hint of expectation on their faces.

"Yes, it's done, isn't it? Take it for yourselves!"

Zhou Tian looked at the three people coming in and smiled easily.

"Great! I'll take a look right now!"

Upon hearing this, Jiang Long no longer cared about the relationship between superiors and subordinates. He just glanced and saw a stack of drawings on the dean's desk. A light flashed in his eyes and he hurried forward to pick up the drawings. As for Zheng Tianhua and the other person behind him, they also stepped forward upon hearing the sound. The three of them gathered together and began to look at them.

As they flipped through the drawings one by one, the amazement on the three people's faces became more and more intense.

Finally, after they had finished looking through all the drawings, the shock in the eyes of the three people did not diminish at all, but became even more intense.

"Dean, you have not only coal mining machines and tunneling machines, but also belt conveyors and blasting machines?"

With excitement, Jiang Long couldn't help but ask.

It's no wonder that he was excited. The main reason was that the design level shown by the dean was too shocking. You have to know that it has only been a month. If it were them, in a month, not to mention the entire set of coal mining equipment, even if they could complete the design of a coal mining machine, it would be considered good.

But in the hands of the dean, it was not only completed, but also doubled in completion. Even the entire set of equipment, from production to transportation, was simply a one-stop service.

"Okay, don't say too much if you want to compliment me. Now that we have the blueprints, tell me, the research on the coal mining machine shouldn't be that difficult, right?"

Zhou Tian waved his hand to interrupt Jiang Long, mainly because time was too tight and he had no time to listen to them praising each other.

"Don't worry, Dean. As long as we have the blueprints, we will complete the manufacturing of the coal mining machinery as quickly as possible!"

Upon hearing this, Jiang Long said seriously that although he was not very good at research and development, but in the field of mechanical manufacturing, he was better than anyone except the dean, even if it was an eighth-level worker. After all, who isn't an eighth-level worker?

"Well, then I'll leave the coal mining design to you. Old Zheng and Old Chang, you two will assist Old Jiang first. After I finish designing the automobile production line, you can each take charge of a part!"

"Okay, Dean!"

Zheng Tianhua and Chang Weijun had no objection to the dean's decision. After all, they knew that they were indeed a little inferior to Jiang Long in the field of mechanical manufacturing.

"Well, get busy!"

After saying that, Zhou Tian sent the three people away. He was about to take a break, but then he thought of his goal, shook his head, took out the drawings and started designing the car production line.

Zhou Tian's knowledge about cars is actually not that deep. He just knows that to truly manufacture a car, it is not enough to just process the parts, but also requires some other means, such as stamping production lines, welding production lines, painting production lines, assembly production lines and production lines for various parts.

The complexity of this process is so great that it cannot be compared to that of a home appliance production line, and may even be more complicated.

Even he himself was unsure of how many parts were needed to assemble a car from scratch. Just thinking about the parts needed for the engine, chassis, body and electrical equipment made his scalp tingle.

The number of parts required to make a car ranges from a few thousand to tens of thousands. It is basically impossible to complete a car in one factory.

It is no wonder that cars were called the pearls of industry in the past.

Fortunately, the task he received was not all, only the manufacturing of chassis, body, engine, transmission and electrical equipment. Of course, for a car, these are also the most difficult parts.

The transmission, in particular, is related to whether the transmission ratio between the engine and the drive wheels can be reasonably changed during the driving of a car, so as to achieve smooth starting, acceleration, deceleration and reversing of the car.

It is also necessary to take into account multiple mutually restrictive performance indicators such as power transmission efficiency, gear shifting smoothness, and reliability.

For a car, the transmission is a very important part, even as important as the engine and electrical equipment.

Similarly, the engine, needless to say, can be said to be the power source of a car, and the electrical equipment is the software operation, and its importance to the car is self-evident. On the contrary, the chassis and body are relatively simple, but this is only compared with the first three.

Compared to other parts, the chassis and body are the most difficult parts in manufacturing a car!

Looking at the scene on the drawing, even though Zhou Tian was mentally prepared, he still felt his scalp tingling. After all, domestic automobile manufacturing is just starting out, and the task he received seems to be just the design of the production line. In fact, it is basically the same as researching these things.

The more he thought about it, the greater the loss he felt.
