253 Copper tire cloisonné enamel and thread rolling machine
"Butler, wait!"
When he heard this shout, Polu had already stepped on the pedal and pulled the joystick at the same time.
He turned around: "What's wrong?"
"This machine..."
"Boom!"
Something made a dull metallic collision sound, it sounded like some flying metal hitting the iron sheet.
Case and Goola were like cats who heard the sound of strange footsteps. They looked surprised and uneasy, and their whole bodies tensed up.
They stared closely at the rotating flywheel exposed from the top of the iron-covered machine, as if planning to run away as soon as the flywheel started shaking!
"Boom!"
The crash sounded again.
"Little steward, run!"
"Run!"
Although the flywheel didn't shake, we didn't know who was taking the lead. The two of them shouted, no longer hesitated, turned around and ran away! This fully demonstrated the keen reflexes they had honed in various new machine tests!
Their shouts were so sincere and they ran so devotedly that Boru, who had no idea what was going on, could not help but think that they had discovered some problem that he had not discovered. Although they always carried amulets with them, they still
He couldn't help but join them and ran out of the laboratory!
When the three of them gasped and leaned against the wall outside the laboratory, Bolu had time to ask: "You two... running... why are you running? Nothing went wrong?"
"No... no problem. Then, young manager, why are you running?"
"You two ran so decisively, I thought you found some problem that I didn't find. What exactly is the situation?"
Bolu looked back at the laboratory: "Is there nothing wrong?"
Geora gasped and raised her head:
"That sound, a thumping sound, was like the sound of something hitting the iron sheet. It didn't sound like the sound of a machine part. Instead, it sounded like the impact of some parts flying out."
"You mean that ding-dong sound? That's the sound of the screw popping out of the machine after it's done! It's okay, it's okay."
Polu suddenly realized that it seemed that because he had just stood in front of the machine, blocking their sight, they mistook the sound of screws flying into the bucket as the sound of the machine being damaged.
After some explanations, the three of them walked back into the studio.
During this period, the regular thumping sound kept echoing behind them.
"Is this the sound you are talking about?"
Boru walked quickly to the machine and motioned for them to look at his feet.
The two people who walked back to the machine looked at the iron bucket pointed by Bolu. At this moment, a black figure suddenly flew out of the machine, hit the iron plate with a sound, and bounced twice to lie down safely.
At the bottom of the barrel.
"Yes, that's the sound. But what is it? A screw?"
"Yes, it's just screws."
The two of them breathed a sigh of relief and began to observe the new machine intently.
This machine was different from the huge, steam-powered machines they were familiar with.
They couldn't see the familiar drifting steam, nor could they hear the familiar roar of the steam engine. Instead, there was a faint buzzing sound, as the lubricated piston moved back and forth, driving the flywheel to rotate.
While they were talking, in the direction Bolu was looking, you could see the exposed iron block being lifted up, and a steel rod that had fallen along the track onto the processing surface fell to the position waiting to be processed.
At the same time, a copper plate glowing with blue magic held down the steel rod, and then with a fierce and unstoppable momentum, it fell straight from top to bottom along the track. It pressed against the steel rod.
The rod rubbed and rotated on another copper plate that also shone with magical light.
When it hit the bottom, the still-rotating steel rod flew out with inertia. Before the two of them could react, it had already smashed into the iron bucket under the machine, making a thud that made the three of them run wildly.
Voice.
"Is this done? So..."
"Boom!"
Before he finished speaking, another screw also fell into the basket.
"……quick?"
Everything happened so fast that there was no time to even have a sip of tea or a bite of bread. If humans were allowed to use their own hands to do it, they would not even have time to fix the steel rod on the vise. But on this machine, it looks ugly.
, driven by a solid machine, a screw was processed in just the blink of an eye?
With an expression of disbelief, the two of them stared fearfully at the two copper plates that were fixed on one side and sliding up and down on the other. It was as if there were some demons and monsters lurking in the small blue light in the two copper plates.
When they get close, they will jump out and eat people.
On the copper plate, their concentrated magic is so strong and tame that it almost solidifies into a glass-like blue solid on the palm-sized work surface!
It looks like a warm gemstone, like glaze wrapped on a copper base, like the sky, or like the ocean. When you look up, you will feel a suction, making it impossible to look away easily.
After a while, Bolu heard Geola's question in the silent thumping sound.
"Can we take one out and look at it?"
Unlike Case, who had almost leaned up to the copper plate and carefully observed the movement of the two copper plates, Goora seemed a little strangely weak, and even his usually loud voice seemed to have become smaller.
"Take it."
Bolu turned off the machine smoothly and watched with some regret as the beautiful blue color lost control and disappeared into the air.
Case impatiently pulled out the iron cylinder from under the machine, grabbed a handful from it, pulled one out and raised it to his eyes, and looked at the light carefully. While looking at it, he kept mumbling: "How can this thread be like this?"
Perfect? How did this machine do it? I can’t see anything wrong with the depth, spacing and shape of the grooves with my eyes. Goola, Goola!”
When he turned around, he found Geola staring blankly at the screw in his hand: "What's wrong with you?"
Geola smiled bitterly and replied: "Look at the speed of this thing. What kind of things have we been building in the first half of our lives? Driving a few long nails a day makes us feel very powerful, without even a thread."
"Geola, you have built so many things, you have even improved the crusher, and you have participated in the manufacturing of so many big things. How come you still lament about such a small screw?"
Polu doesn't quite understand, so it shouldn't be a problem.
Geola shook his head and seemed to cheer up a little: "Smith brought the screw rod here by car, and I think it was already very fast. If it had been in the past, I would have been scared to death by this machine. We
These old guys who have made threads by hand can all see how powerful this machine is. Even this kid Keith has never made this kind of threads by hand."
"Handmade? That was before I came to Hongshan, right? Has this kind of thread appeared?"
"Yes, it has been many years. I was not yet transferred to the furnaces and foundries."
Geora showed an expression of recalling the past.
"Let me think about it, it was also something brought out by alchemists at that time. It should be an accessory of the bell tower, because in the end we cast a big bell. It was a very thick pillar with spiral grooves. I don't know what it was called at the time.
I don’t know, I don’t know which part it is, and we still don’t know how it was installed in the end.”
Geola stretched out his hand, made a shape as thick as an arm, and laughed:
"But it's so thick that it definitely can't be made into rivets. It can't be burned when it's put on a shelf, but it can't be hammered unless it burns red. It's definitely impossible to hammer it into shape if it's so thick."
"That doesn't necessarily require rivets. Leave a hole in the steel pillar and install a reverse bowl. Apart from being a little wobbly, it's not impossible to insert an iron rod as a pin."
"Then I don't understand. We first forged for a long time, then used a file to grind it into a round rod, and finally took advantage of the red heat to use a small chisel to carve out the texture bit by bit, and finally polished it smooth. I'm still confused
I remember how tired I was at the beginning, why did I think that way was so natural?"
Geora shrugged her shoulders, seeming to have finally recovered from the shock.
"It's great that screws have this kind of background, so I don't have to explain them."
At the same time, Polu also heard other information from Geola's words: "Wait a minute, do you still remember the structure of the bell tower?"
Polu has long wanted to build a bell tower on the island.
The kind with a dial.
But I really have never been exposed to clocks, so I really don’t know where to start.
"I don't remember. We haven't even seen the structural diagram. Didn't I say before that we are never allowed to see the whole thing when we are asked to build it. Maybe we don't even know what it is used for after it is built."
Seeing that the two of them still didn't bring the topic back, Case finally couldn't hold it in anymore: "Little manager, how did you get this thread made by just rubbing it here?"
"Ah! This, wait."
Polu took out a long handle from the cabinet under the stopped machine, shook it a few times in the bayonet next to the two copper plates, and pulled out a pair of mottled red copper plates from the machine.
He knocked on the thin copper plate: "Originally, I planned to use the best alloy to make this washboard. But since I harvested enough copper last time, I can finally use copper with better performance to make the spell substrate.
At the same time, I also picked up some other techniques from books, Star Island, and various places. So I thought of new methods."
He spread out the two copper plates so that the side with dense diagonal lines faced the two of them.
"These two boards are the thread-rolling mold. I originally wanted to use expensive fine gold to enchant the turning tool, but now I see it's useless! I just use my not-so-large magic circle to strengthen these fixed shapes.
The inlaid steel wires are strong enough!"
"Young manager, you've already used the magic base plate. Why don't you just shape it and let it form texture directly? You also have to rub it. Isn't it a bit unnecessary?"
"The extruded thread is equivalent to cold forging, and the strength will be slightly better. Anyway, after a thin force field is formed on the steel wire, ordinary steel wire is surprisingly hard, which greatly reduces the difficulty of making molds.
.In my tests, the force field had almost no friction, and even lubricating oil was saved.”
Polu sighed:
"Magic seems to be very restrictive, but as long as you use your strength, it's so easy to use that it's unreasonable."
"However, I still don't understand how the lines on this plane turned into circular threads?"
"See the slash on this?"
"You see these lines, they are actually the flat expansion of these threads. When the steel rod rotates and passes above, as long as the pressure is strong enough and the lines are hard enough, the plane lines will naturally be extended to the steel rod, from top to bottom
Turn it down and it will form perfect lines on its own.
This board, if you understand it as a turning tool, why are you so arrogant? The mold cannot rotate, so let the workpiece rotate! Isn't it just rotating when it is rubbed off? Seriously, complete these lines on a flat surface
, it’s easier than cutting directly on the steel rod in a circle.”
Looking at the confused expressions of the two people, Polu felt a headache: "Tell me, what don't you understand?"
“What is the expansion of a thread on a flat surface?”
Hearing this question, Bolu was stunned, and the screw in his hand almost hit his foot.
How to explain the unfolding of a three-dimensional spiral on a plane to primary school students is very urgent.
After holding it in for a long time, Polu slapped his head. He took a piece of paper, cut it into a long and even strip one finger wide, and called the two of them to come over: "Look, if I wrap it straight, is it this piece of paper?"
Can’t push to one side? Can only be stacked?”
"Now let's tilt the paper slightly, then wrap it around it and look at this edge carefully."
Polu carefully wrapped one side of the paper around the screw along the angle of the thread.
"Now the paper strips are so wide that they overlap each other, but is this edge just advancing along the threads on the screw?"
"Look carefully at the overlapping sides of this piece of paper. Do their sides now form equidistant diagonal lines on this round rod?"
"But isn't this board full of slashes? Why are there so many?"
"Because it's fast! If you want to use a thread to cut such a long spiral, you have to... it's very long anyway! The threaded area is only so long. As long as I have such a wide mold and enough pressure, I can finish it with just one twist.
Son!"
"So with so many wires, when they are turned, won't they interfere with each other and mess up the threads?"
Case asked another question.
"ah!"
Polu was a little crazy, and he took a piece of paper again.
"Okay, now we draw this slight diagonal line on the paper, and now the angle is the same as the mold. We wrap it around the screw, and then pull out the screw."
Polu kept the scroll and called the two people over.
"Come on, look at the lamp! Are the lines all overlapping now? The same goes for threads. As long as your angles and spacing are consistent, when you wrap this cylinder, the first diagonal line and the second diagonal line must coincide.
!So based on the same principle, the first line and the second line on the thread line must also overlap! In other words, no matter how many times the cutting line passes through this mold, it will only form one continuous thread."
Bolu spread his hands helplessly: "If you still don't understand, I can't help you now. I'll make a teaching aid for you later."
To be honest, Polu also felt that it was really difficult for them to understand this kind of problem.
He sighed, the cultural level needs to be improved urgently!
"When I go back to the Precision Institute, you all come to my lectures!"
