Chapter 199 Assembling the Excavator (Third Update)

It was still dark on Sunday. The door of the motorcycle factory was opened, and the four-wheel drive vehicles drove out of the factory. The door of the steel rolling mill was also opened, and they were all four-wheelers. There were thirty-two four-wheelers in total.

Liu Hai drove the factory director's car, Li Bing, the logistics section chief of the steel rolling mill, the accountant in the factory, the logistics section chief of the motorcycle factory, and the accountant each took a bag of money and sat in the car.

On the township government side, many people are waiting in the farmland on the roadside. Behind these people are hills of cabbage, all covered with straw.

As soon as it dawned, I saw cars of Sibuxiangs suddenly appearing. Li Bing and the accountant from the steel rolling mill got out of the car. Some workers got off from the Sibuxiangs behind them. These workers worked overtime for free today in exchange for being able to bring back a sack of cabbage.

Liu Hai took several cars and drove to the sunbathing area in his village.

No one came to the motorcycle factory. After all, Liu Hai came from his own village. Li Bing brought the workers here for safety.

Cabbages and radishes were piled around the drying area.

"Captain, first load the sacks and then weigh them." Liu Hai asked someone to drop the bundles of sacks and said.

"Okay, all of you, watch carefully and don't follow the sack." The captain shouted loudly.

The members started to pack radishes, and it was obvious that the radishes were very good.

While pretending, weighing, and getting in the car, just stare at your bangs, don't make yourself embarrassed.

Soon a car was loaded. This thing said three tons, but at least five tons. After all, the roads were good.

At noon, the team killed chickens and made roast chicken and steamed buns.

There were more than 20 cars in his team, and several cars ran back and forth several times. The captain squinted his eyes while holding the money, and the cabbage was peeled relatively well.

"Uncle, I'm leaving first." Liu Hai didn't have time to go home, so he sent the accountant and others back first.

"Okay, okay!" The captain was very happy. This is all money, totaling more than 200,000 catties.

More than 200,000 kilograms sounds like a lot, but it’s actually not that many tons. Even a modern large trailer can haul tens of thousands of kilograms, but it’s a lot at this time.

It was almost done here in the countryside. Liu Hai waited for another hour and ate here. Before leaving, the village also gave chickens, eggs and so on. Everyone had them, including the drivers, but Liu Hai didn't ask for them.

Liu Hai was the only one who didn't drink, and everyone else drank, even those who drove like crazy. It was common to drink and drive at this time.

When Liu Hai returned to the factory in the evening, he didn't plan to go home. It was very comfortable to live in the laboratory with the heating. He could just go back to the courtyard occasionally.

The next day, Liu Hai gave a detailed report on the cabbage harvest. Sun Aiguo listened to this little cabbage and said, "It's not much. Our factory is expected to have more than 10,000 people next year. But Xiao Liu, don't take the initiative for these favors." Give, even if you give, don’t agree even once. Do you know that if you give too easily, others will feel that there is not much affection for you.”

"Thank you, director, thank you, director."

"How's that four-cylinder diesel engine doing?"

"Production has already started, it's not very difficult."

“That’s good, that’s good.

Sun Aiguo didn't have time to say anything to Liu Hai. He was leading people to attack the boring machine. There are many technologies in the boring machine, mainly heat treatment technology.

At Liu Hai's suggestion, Sun Aiguo established a special heat treatment workshop. This workshop was kept secret from the outside world and was divided into many processes. Some processes had no effect. The true and false were listed together, so that even someone could get the complete The heat treatment process will also fail.

In addition, you can also make some specious additives and so on. Anyway, put the real and fake together.

In later generations, we sometimes visit other people's factories, and others just mess around. At worst, after the people leave, they can just do it the right way again.

It's December. Liu Hai counted on his fingers and realized that Wang Hongmei's life should be approaching soon. Giving birth to a child in this era would mean death. When Liu Hai was almost ready, he would go back a few more times. Anyway, he now owns all kinds of cars.

The casting of a four-cylinder diesel engine is much more difficult, but it is not as abnormal as a large diesel engine. The process technology of large castings is very complicated, and there are too many temperature variables. If one is not mastered well, it will be useless.

The four-cylinder one was better. Liu Hai and Li Dali and three others cast the cylinder block. The first time it was cast, it failed. This was the second time.

After the second casting, the bangs were carefully inspected and passed, and then the subsequent processing began.

"Section Chief, what are we doing here?" Li Dali and the other three thought they were also making cars, but the more they worked, the more they felt something was wrong. What's wrong? The tracks are all out?

When Liu Hai heard Li Dali ask, he said, "It's a kind of engineering machinery. Don't ask, just make it quickly."

"Okay." In the impression of Li Dali and the others, the only thing with tracks seems to be the legendary tank.

Not only Li Dali and the other three were a little strange, but the steel rolling mill was also a little strange. The parts sent by the motorcycle factory were getting more and more strange. In fact, they had never seen them before. For example, the driving wheel of the crawler track was also processed after forging, but it was still missing. Large casting press, or insufficient casting technology.

In fact, it can also be cast, but the materials are different. Bangs tried not to use too many material technologies that were ahead of the times.

Sun Aiguo hasn't paid attention to Liu Hai recently, because Sun Aiguo is doing a big thing recently, and the boring machine project must be completed before this big thing comes.

As for the people below, the people in the equipment department couldn't understand the drawings. After getting the drawings, they sent them to the steel rolling mill. After the work was done at the steel rolling mill, they sent them over. The communication room no longer notified the equipment department, but directly notified the maintenance department. The equipment department directly informed the equipment department. commanded.

So Sun Aiguo didn't know about the weird parts made by bangs.

All the parts of the excavator were in place. Liu Hai touched his chin. This thing needs to be assembled outdoors. The house in the laboratory is not too big. Fortunately, this is a 90 excavator. If it were bigger, it would need to be driven. .

Finally, the parts were almost ready, and Liu Hai began to weld the big arm. The two sides of the big arm were processed after forging. Liu Hai did the welding himself, for fear that Li Dali and the others would not be able to weld well.

After burning for two and a half days, Liu Hai felt that he would never weld again in the future. The welding was done indoors, and Li Dali and three others also assisted in heating, using a spray gun.

Due to the large-scale independent production of 100-ton hydraulic presses, Kyoto has begun to use gas cylinders, which are gas from the coking plant.

Li Dali and Li Dali didn't know why the section chief did this, but it was right as the section chief ordered.

As for why there were two of them, one of them went to the boring machine production workshop as a technical guide.

The reason why it is indoors is because the temperature outside is too low. At this time, there is no such thing as secondary welding. It is actually not complicated, but Liu Hai now wants to get the excavator out and then go back to his hometown to have a look.

Once the excavator is built, it will be ready to go before the Chinese New Year this year, and this year’s plan will be completed.

The entire weld is made in one go. There are four welds in total. There are two layers of steel plates above and below the big arm. These two layers of steel plates and the forgings on the left and right sides of the big arm make up four welds.

In addition to the forward and backward operating levers, the old excavator also has seven or eight operating levers, all of which are hydraulically controlled, while modern ones are controlled by wire.

So after getting on the car, you will see two rows of operating levers. Use these operating levers to rotate the excavator left and right, control the big arm, forearm, bucket, etc.

In the open air, Liu Hai and Li Dali built a simple shelf, which was mainly used to lift the engine and the equipment in the cab above the excavator's rotating mechanism.
