Chapter 239 This matter is not that simple (please subscribe)
Xu Ye raised his head and looked at the other person seriously.
Obviously, he didn't know the other person.
After a moment of silence, Xu Ye said calmly: "These so-called evidence is false."
"The machinery and equipment I manufacture is for the convenience of the village production, and has never been used to make profits for myself. The money for selling those threshing machines was collected by the brigade. I only used some to purchase raw materials."
"As for hiring labor, it's even more nonsense. All my actions were approved by the brigade and were completely legal. We work collectively and all work points."
The middle-aged man obviously didn't expect Xu Ye to be so calm. He was stunned for a moment, and then said sternly: "Don't argue! The evidence is conclusive now, you'd better explain honestly, otherwise you'll feel better!"
Xu Ye knew that the other party was determined to punish him, and no matter how much explanation it would be futile. He simply stopped talking and just looked at the other person coldly.
When the middle-aged man saw Xu Ye not saying anything, he slapped the table in anger: "Okay, don't say it, right? Then don't blame us for being rude!"
After saying that, he turned around and left the room and closed the door heavily.
Xu Ye glanced at the dark room and knew that the other party was going to test his willpower.
After all, no one can stand the lock in a small dark room.
But he didn't have this trouble because he could go to the mechanical workshop to work.
Just, he didn't know what new task the system had released.
After his consciousness entered the mechanical workshop, he saw a new task.
[Task: Make an electric welding machine]
[Task reward: 100 mechanical attribute points, a mechanical design drawing and related information. 】
"It turns out that it is not a tractor, but an electric welding machine?"
Xu Ye was very surprised.
Seriously, he really needs a welding machine.
I've wanted to buy it for a long time, but I haven't bought it yet.
If you can really build one by yourself, it will be much more convenient.
How can we use mechanical tools be missing?
When I went to the county town to collect various books, I did come into contact with some books about electric welding.
The basic structure and working principle of the welding machine quickly emerged in my mind.
He once saw the design drawings of an electric welding machine in a book. Although he couldn't remember the details clearly, he still had the general direction.
Electric welding machines can generally be divided into two types according to the output power supply type, one is AC power supply and the other is DC power.
Using the principle of inductor, the inductor will produce huge voltage changes when it is turned on and off. The high-voltage arc generated by the positive and negative poles in an instant short circuit is used to melt the solder on the welding rod to achieve the purpose of atomic bonding. "First of all, a transformer is needed. As long as this is solved, the difficulty of making an electric welding machine will be reduced." Xu Ye suddenly had a direction, and then began to look for suitable materials in the mechanical workshop.
Here, there are all kinds of materials.
If there is no, you can use mechanical properties to exchange it, and you don’t have to worry about not having the materials you need.
Xu Ye stood in the mechanical workshop, his eyes swept across the corner full of parts, and he had a clear plan in his mind.
The core of making an electric welding machine lies in the transformer. The design of the transformer is not complicated, but it requires precise calculation and meticulous production.
He took a deep breath and started to take action.
Xu Ye first recalled the basic principle of the transformer in his mind: through electromagnetic induction, the input voltage is converted into the required output voltage.
The output voltage required by the welding machine is low but the current is large. Therefore, the design of the transformer needs to focus on the number of turns and wire diameter of the coil.
The iron core of the transformer is the key to electromagnetic induction.
Xu Ye found some silicon steel sheets in the mechanical workshop, which are ideal materials for making iron cores.
He cut the silicon steel sheet into "E" and "I" shapes, and stacked them interlaced to form a closed magnetic circuit.
"The iron core should be stacked closely and minimize magnetic resistance." Xu Ye muttered to himself while fixing the silicon steel sheet with a clip.
The next is the most critical step - winding the coil.
Xu Ye found a simple wire winding machine, which was the tool he had previously assembled with used parts.
He fixed the iron core to the winding machine and began to wind the primary coil.
During the winding process, Xu Ye constantly checked the flatness and insulation of the coil to ensure that there were no exposed wires or loose parts.
After the winding was completed, Xu Ye fixed the coil to the iron core and wrapped the entire transformer tightly with insulating tape.
He turned on the power supply and used a multimeter to test the output voltage.
"The primary voltage is 220V, the secondary voltage is 36V, perfect!" Xu Ye nodded with satisfaction. "I didn't expect that I could get the transformer so smoothly?" Xu Ye looked at his work and couldn't help but smile. "It seems that the ability I have mastered now has exceeded my expectations. I can actually rub a lot of things out of my hands."
"Even if it's not in a mechanical workshop, in reality, it won't be difficult for me to rub such a transformer with my hands."
Thinking of this, Xu Ye was full of energy. "But it's a pity that the current direction of the wind has not changed, and many things cannot be done." After a helpless complaint, Xu Ye prepared to start the next step.
What Xu Ye wants to do is an AC welding machine, which is the simplest and does not need to involve any circuit board or the like.
It is completely different from the electric welding machine like later generations.
However, the technology and knowledge reserves he currently masters do not allow him to create the kind of electric welding machine he has in later generations.
One capacitor is enough for him to have a headache.
However, he felt that he could still gradually move towards the electronics.
Xu Ye found a few thick copper wires from the corner of the mechanical workshop and prepared them to make cables.
He connected one end of the copper wire to the output of the secondary coil of the transformer, and made the other end into an electrode clip.
To ensure safety, he wrapped the cable tightly with insulating tape to prevent leakage.
"The electrode clamp needs high temperature resistant materials, after all, the temperature is very high during welding." Xu Ye thought, while finding a high temperature resistant metal sheet from the pile of materials.
He bent the metal piece into the shape of a clip and secured it to the end of the cable with screws.
Next, Xu Ye found a few metal wires of appropriate thickness as temporary welding rods.
Although these metal wires are not special welding rods, they can also be used.
After all, he did not really take it out, but to complete the system's tasks.
After everything was ready, Xu Ye turned on the power supply and carefully tested the welding machine.
He picked up the electrode clip, clamped the temporary welding rod, and then gently touched a scrap iron plate.
"Sizzle--"As a burst of sparks splashed, the welding rods successfully connected the two iron plates together. "It's successful!" Xu Ye clenched his fists excitedly.
Although this welding machine looks simple, its functions fully meet the needs.
He tested several times in succession and found that the welding machine has stable performance and sufficient arc strength.
At this moment, the system prompt sounded:
[Task completion: Make an electric welding machine]
[Reward: 100 mechanical attribute points, a mechanical design drawing] A light flashed in front of Xu Ye's eyes, and then his mechanical attribute points increased by 100 points. At the same time, a brand new design drawing appeared in his hands.
After opening the drawings, a smile appeared on Xu Ye's face.
"5-ton gantry hydraulic press!"
"That's great, this design drawing is exactly what I need!"
"Where is the system, where is the information?"
With this gantry hydraulic press, Xu Ye can be used to transform it into the ceramic tablet press he wants.
And hydraulic presses can be used to make many types of equipment, which is a very important technology.
Xu Ye felt happier than winning the grand prize by being able to obtain the drawings and knowledge of this.
Xu Ye couldn't wait to open the information provided by the system and read it carefully.
This information not only contains detailed design drawings for the 5-ton gantry hydraulic press, but also includes a detailed description of the working principle of the hydraulic system, the material selection of each component, and the manufacturing process.
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
"The working principle of a hydraulic press is to transmit pressure through hydraulic oil, drive the piston to move, thereby generating huge pressure." Xu Ye was reading while building the overall structure of the hydraulic press in his mind.
Xu Ye found that the core components of the hydraulic machine include hydraulic cylinder, hydraulic pump, control valve, and oil tank.
The hydraulic cylinder is responsible for generating pressure and pushing the piston movement.
Hydraulic pump converts mechanical energy into hydraulic energy to provide power.
The control valve is responsible for regulating the flow direction and pressure of the hydraulic oil.
The oil tank is used to store hydraulic oil to ensure the normal operation of the system.
It doesn't seem difficult, but it will be difficult if you don't understand the relevant knowledge and want to create it out of thin air. "The design of the hydraulic cylinder is the key, it must be able to withstand high pressure and ensure sealing." Xu Ye thought to himself.
He carefully checked the design drawings of the hydraulic cylinder and found that the information provided by the system marked the material selection, processing technology and installation methods of the hydraulic cylinder.
"It can be done in a mechanical workshop, but it will be difficult to return to the real world." "It's still too backward!" Xu Ye said with regret.
But he was also very satisfied, after all, this knowledge was priceless.
With this knowledge, he can also gradually solve the process problems in reality and then build this kind of gantry hydraulic machine.
At this moment, Xu Ye suddenly heard footsteps coming from outside.
He immediately became alert and quickly withdrew from the machinery workshop and returned to the small dark room in reality.
The door was pushed open and the middle-aged man walked in again.
His face was even more gloomy than before, and he was obviously dissatisfied with Xu Ye's silence. "Xu Ye, how are you thinking? Do you want to give honest advice?" the middle-aged man asked coldly.
Xu Ye raised his head, looked at the other person calmly, and said lightly: "I have nothing to explain. Everything I do is for the production of the village, and there is no violation of regulations."
The middle-aged man obviously didn't expect Xu Ye to be so tough. He gritted his teeth and said viciously, "Okay, since you don't want toast or eat the punishment, don't blame us for being rude!"
"Come in."
As he said that, two people walked in with special chairs.
Xu Ye knew that this was the kind of tiger bench.
Xu Ye sneered in his heart, he was not worried about this method.
Anyway, he is still thinking about entering the mechanical workshop to get rid of all the knowledge points of the hydraulic press.
"Don't let him sleep, it's not long before genius is dawn." The man explained and left directly.
Xu Ye was not in a hurry to enter the world of consciousness, but looked at the location of the window.
It was already eight or nine o'clock in the morning. It was a night after that, and I don't know how Jiang Ruoan and the others were doing.
Xu Ye himself didn't care, but he was very worried about Jiang Ruoan and the others.
Needless to say, they must have had insomnia last night.
He guessed that Gu Yun would definitely take them to the county town to find the old leader, after all, this was the fastest solution.
If the other party can't get himself out even if he comes forward, it means that what he encounters is not that simple.
A night passed, and Xu Ye felt that something might not be right.
It doesn't seem like it was reported by ordinary people, it seems like it was deliberately targeted.
Otherwise, Fan Dajun and Yang Zongming should not have been implicated.
According to those people, Fan Dajun and Yang Zongming had no problems to deal with.
They have always done things according to the rules, and many of the previous things were applied for.
Xu Ye feels that he doesn’t look like a person from the village or a person from a commune or a county town with this ability.
You should only use this method to deal with yourself.
Some memories of being in the capital emerged in Xu Ye's mind.
The people whose father offended them have this ability and they also have reasons to target themselves.
Of course, Xu Ye didn't ask.
I asked, but I won't find any results.
What he can do now is wait.
Wait for Lu Ming and the others in Shangxi Village to start their activities, and wait for Gu Yun to find the old leader.
Having my thoughts closed, Xu Ye entered the system space again.
At this time, the system has released a new task.
[Task: Make a thread processing machine tool. 】
【Task Reward: Reward 50 mechanical attributes, a mechanical drawing and related knowledge points. 】
When he saw this new task, Xu Ye's mouth couldn't help but twitch.
Originally, he thought the task was getting harder, but he came up with a thread processing machine task.
But in reality, Xu Ye also needs this thread processing machine tool.
Of course, he did not immediately make a thread processing machine tool, but continued to learn the knowledge of the gantry hydraulic machine.
Xu Ye continued to study the design drawings and related information of the 5-ton gantry hydraulic press in the mechanical workshop.
He knew that the production of hydraulic presses not only requires theoretical knowledge, but also requires a deep understanding of materials and processes.
Although the system provided detailed information, he still did not dare to take it lightly and decided to understand every detail of the hydraulic press first.
Time passed little by little, and in the real world, the person who was responsible for watching Xu Ye would check whether Xu Ye was asleep from time to time.
However, his consciousness is not in reality in the mechanical workshop, and it looks like he is thinking about problems and not sleeping.
Of course, as long as Xu Ye is willing, he can also let his body fall asleep and make his body look awake.
