Chapter 773 The collision between the advanced and the backward
The people from the research institute did not refute, but just smiled indifferently. They just had not seen it before. When these people saw the power of the steam engine, they would probably be the first to praise the steam engine to the sky.
Luo Chong went to the scene as usual because he also wanted to see the steam engine being used for work.
"Start assembling." He arranged, and the work began.
The operating table of the table saw was already made, and the site was vacated in advance. The researchers only needed to install the steam engine on it.
In order to facilitate later maintenance, according to Luo Chong's requirements, the steam engine was placed outside the operating table. In this way, in order to extend the distance between the flywheel and the table saw power wheel, a relay power shaft had to be used in the middle to connect them. The two ends were respectively covered with belts on the relay shaft to ensure the long-distance transmission of the steam engine and the table saw.
Because the Iron Horse Type 1 had been pre-installed and perfect, the assembly was very fast this time. It took only about half an hour to install all the parts in place.
On both sides of the long table saw, one side is an oversized circular saw blade, with a diameter of one meter and a height of 45 centimeters above the operating table, which is enough to split logs of normal size, while the other side is a circular saw that is half the size, with a diameter of 60 centimeters and a height of 25 centimeters above the surface, which is specially used to cut some delicate parts of the material.
Although it is still a bit large, it is enough for large wooden products such as sailboats.
Seeing this strange new saw being installed, many workers in the wood processing workshop gathered around, because whether it is a hydraulic sawing machine or a windmill sawing machine, the Han tribe has always used long saw blades to cut logs by mechanically pulling the saw blades, and this table saw in front of me actually uses a circular saw blade, which is really the first time I have seen it.
"Chief, is this thing for us?" A workshop manager ran over and asked Luo Chong.
"What else, why would you keep it here?" Luo Chong asked back with a smile.
"Then how should this thing be used?" The man asked again.
"We are about to test the machine. You can arrange some workers to help. Just listen to the instructions of these researchers. Also, let your people learn the operation procedures well. Don't wait until we leave and you can't use it. Also, this thing is very dangerous. Be sure to pay attention to safety when using it." Luo Chong reminded again.
"Don't worry, leader. Although I don't know what this thing is, all mechanical things are dangerous, and windmills are no exception. We are always careful when we work." The person in charge hurriedly explained, he was afraid that the leader would find fault with him.
"Well, go ahead." Luo Chong nodded, looking at the empty workshop wall, he felt that it was very necessary to paint the characteristic slogan of our rabbit, such as "observe discipline and work safely", on the wall.
The researchers quickly lit the fire. The most common things in the wood processing workshop may be scraps and waste wood. In addition to keeping them for their own use, most of the remaining ones will be sold to the people as firewood, or processed into smaller wood to make some furniture or something. But now with the steam engine, a big fuel consumer, it is estimated that there will not be much left in the future.
As the fire grew stronger, they also threw some coal into the furnace. In terms of burning resistance and calorific value, coal was of course more effective.
When the gravity valve on the boiler issued a high-pressure alarm, the researchers immediately pulled the joystick that controlled the steam pipe. High-pressure steam poured in and began to push the piston to work. The flywheel also drove the circular saws on both sides to rotate rapidly through the transmission belt.
The two saw blades vibrated with a buzzing sound at the same time, and then they started to rotate rapidly at a speed that could not be distinguished by the naked eye. Although they did not understand the exact principle, the workers in the workshop still felt that it was very magical. If this thing could really saw wood, the speed must be very fast.
"Come here, bring a piece of wood over." The person in charge of the workshop saw that this thing finally started, and then immediately ordered the workers to carry the wood over.
A log that had been cut into a flat bottom was carried by more than 20 people and sent to the sawing table. The person in charge adjusted the fixed width baffle on the table saw according to the researcher's instructions, and then began to let the workers push the wood forward.
One side of the log leaned against the fixed width baffle, and the head began to slide forward. When it touched the high-speed saw blade protruding from the operating table, a large ball of sawdust was instantly knocked out of the log, and the front end of the log was successfully split into a gap. The rising sawdust directly formed a line in the air and sprayed out a high section. Such an amazing momentum and such an exaggerated sawing speed really scared everyone.
The workers and the workshop manager were stunned. The front end of the log was stuck in the saw blade, and it began to heat up and smoke due to the high-speed friction with the saw blade.
Luo Chong frowned and scolded, "What are you doing? Push forward. Watch your arms. Be careful. If you touch the saw blade, you will be cut off instantly."
"Oh, did you hear that? Be careful. Don't leave your arms on it." The workshop manager immediately came to his senses and repeated Luo Chong's words. The workers continued to push the log forward.
The log was pushed forward smoothly, and almost no resistance was felt. Every time the workers pushed forward a distance, the log would be instantly split by the high-speed rotating saw blade, and a large amount of sawdust would erupt outward. It took less than half a minute to successfully cut a piece of wood from a log more than ten meters long, and the cut surface was very smooth, at least much smoother than that cut by a windmill sawmill, and there was almost no need for post-processing with a planer.
Such amazing efficiency makes people doubt whether they are dreaming or not. They look at the windmill sawmill next to them. The huge wooden gears and connecting rods are pulling the saw blades to cut the wooden boards in an orderly manner. The speed that they usually think is not slow is just like a turtle crawling compared to the steam table saw in front of them.
This guy, the efficiency is too exaggerated.
Just as everyone was sighing, Luo Chong ordered them to send a group of people to stand on the other side of the table saw and send the just cut wooden boards to the small saw blade on the other side to repair the excess bark parts on both sides.
This time, because the wooden board is much lighter, the cutting speed is faster. After hearing a few squeaks of saw blades hitting the wooden board, a square wooden board was cut off.
At this time, there are researchers who tell them the function and use of the automatic shaving roller, and then instruct the workers to stand up the wooden board and push it on it. Wow, this time, even manual shavings are saved. The pushed wooden board is smooth and slippery. If it is polished with sandpaper, it can probably be used as a handicraft.
They were just a wood processing workshop, a place for pre-processing materials, and had never seen such a neat finished product. Those who initially thought that the steam table saw was inferior to the windmill sawing machine turned their faces and praised this artifact without any embarrassment.
That's right, from now on, the title of "artifact" of the windmill will probably be directly transferred to the steam engine.
Seeing the success of the steam table saw in front of him, Luo Chong finally put his mind at ease. This thing can finally be proved to be used for work, and the efficiency is super high.
