C344 Installing Bearing
This required a specialized hydraulic press to be installed. In the factory, there should be a lot of such tools, but now, in Zhang Xiangyang's place, there was a serious shortage of tools.
Without specialized equipment, this bearing could not be installed. As for buying equipment now? That was impossible. One had to know that many factories had already entered the New Year mode and could not accept orders.
What should he do?
Zhang Xiangyang's expression was very ugly. To start a business on his own, this path was really hard to walk on. All kinds of problems were laid out in front of him. In the past, at the factory... What did he lack? He just needed to make a report. He was not in a hurry to start work even if he could not. In any case, the salary was allocated to him by the government.
But now, he had to deal with everything on his own.
"Is there no other way?" Zhang Xiangyang said, "We are all old masters. How can we do that?"
When there was a lack of tools, one could use earth magic to get on the horse. Since Zhang Xiangyang asked everyone this, as old masters, there was naturally a way.
"The bearing can be heated first." Master Du said, "After heating, we can install our turning axis inside."
It was a very simple principle, thermal expansion and contraction. As long as it was heated, the axis inside the bearing would become bigger, and then the axis could be installed inside.
"After installing the axis inside, we can use a hammer to smash the outside of the axis into the shell."
There were two sides to the installation of the bearing. The inside was connected to the axis, the outside was connected to the shell, the inside was heating, and the outside was directly violent.
However, this installation method was harmful to the bearing.
As an old master, Master Du was clear that the temperature of the open bearings should not exceed 120 degrees Celsius. The bearing with a sealed part and a dust-proof cover was not even allowed to be heated to above 80 degrees Celsius.
With such a low temperature, the effect of thermal expansion and contraction was still very small. It was almost no different from not being heated. This kind of process was to install a large bearing, heat it up slightly, and then press it in with a hydraulic press.
But now, they had to heat the bearing directly. The temperature was not several hundred degrees, so it was absolutely useless.
"Since you already know, why are you still standing there?" Zhang Xiangyang said, "Hurry up and work!"
Work! Master Du put on a mask and thick gloves. He held a welding gun in his hand and gestured to his companion.
The other companion drew a match with his hand and extended it towards the welding gun's head. In an instant, a blazing flame pounced out.
The acrylic oxygen gun was a common workshop processing tool. Now, after Master Du lit the gun, he began to move toward the bearing.
The hot flame roasted the bearing. As an old master, Master Du was clear that when heating the bearing, it had to be evenly heated. There could not be any situation where it was overheating.
Therefore, he had to keep shaking and heating it.
At the same time, when the heating temperature exceeded 727 degrees Celsius, it reached the transition temperature of the bearing steel. The metal structure inside the bearing steel would undergo changes. When the bearing cooled down, the bearing internal hole would not be able to return to its original size. It was usually bigger than the size before heating.
This way, the bearing loosened.
The theory was simple, but when it came to actual operation, who knew how much it reached!
"Come, try it." Master Du shouted.
Another master picked up the axle and tried to stuff it into the bearing, but it immediately stopped moving.
"No, continue heating!"
Master Du could only continue to bake.
"Try again."
"Not yet!"
He was going to roast the bearing! Master Du frowned and then heated it up until the bearing was about to turn red. Then, he easily stuffed it into the steering wheel.
"Alright, installation complete. Next!"
With this first successful experience, the rest of the installation would be done the same way.
Master Du was awesome!
Zhang Xiangyang watched his subordinates work. After installing the axis into the shaft and waiting for it to cool down, he began to stuff it into the outer shell of the converter.
How? They were going to use a hammer to work!
"Bang, bang, bang!" Hammer after hammer continuously smashed down. Finally, the bearing was knocked in.
Then, they installed the gears and the workers and workers started working together. Before the sky turned dark, they had assembled more than fifty of them.
Seeing the sun slide to the west, Zhang Xiangyang was very satisfied. "Everyone, do your best. Let's work for a few more hours."
"Still work?" Instantly, there were people who were dissatisfied.
"The factory is in a hurry. Everyone, work overtime. We have worked until 100 today. You can go back. As for me, I still have to go to the factory to deliver the goods. Tomorrow, we will try to assemble 200 pieces and assemble another 200 the day after tomorrow. We will be finished and we can celebrate the new year. Anyway, this is all the work. If we finish early, we'll go home early and celebrate the new year! "
Zhang Xiangyang had his own considerations in his heart. Back then, Factory Manager Wang had repeatedly reminded him to pay attention to quality. If quality did not meet the standards, he would refuse to accept it.
Although he patted his chest to guarantee it, now, looking at the installation method of the bearing, he did not know if quality was up to standard, but now... There was no other way. If he didn't quickly assemble it... It would still be a breach of contract. The penalty would be enough for him to spend the rest of his life in prison.
He could only rush out!
Since that was the case, it was best to deliver the goods in the middle of the night. Anyway, the factory did not rest during the day and night. If he sent this batch of goods over, he might even be able to load the car.
As long as he loaded the car, what else could he do? In the future, if there were any problems, would he deliver the goods himself or they would produce it themselves? At that time, no one would be able to say for sure whether he would be able to get rid of the relationship.
He was not trying to scam the factory. He was only doing it because he was short on time. When the first batch of goods was sent out, he would get the money. I will buy all kinds of equipment next year. Then I will be able to produce them at a higher standard.
Well, there won't be a next time, there won't be a next time.
Zhang Xiangyang comforted himself like this.
Although the workers had objections, as long as they finished working for the next few days, they could celebrate the New Year. They were fired from the factory. If it wasn't for Zhang Xiangyang, they wouldn't have the money to celebrate the New Year, so they still had to work.
The night was getting deeper and deeper. Finally, at 12 o'clock at night, the workers yawned and looked at the converters on the ground. "Alright, it's over a hundred. We have to go home and rest. I'm so sleepy!"
We are technical workers, not porters. How can we transport 100 sets of Steering Machine into the factory? That's not what we have to do.
