Chapter 1519: Combat Guns

It was almost time, and there was nothing to see outside the window. Su You put the chess pieces into the box.

Seeing Zhao Xu looking at the box eagerly, Su You smiled and said: "I'll give this to Your Majesty. You put it in your schoolbag, then go brush your teeth and wash your face. It's time for us to go to bed."

Zhao Xu then left happily.

The train passed through Zhengzhou in the middle of the night, turned onto a branch road, and headed towards the Songshan Valley.

At three o'clock in the morning, the train arrived at Songyang Arsenal.

Shi Tong of Tiji Songyang Arsenal led a team of factory guards to guard the edge of the station. When he saw Su You and the sleepy Zhao Xu coming down, he quickly stepped forward and continued: "It's hard work to wake you up in the middle of the night.

, why don’t you go to my office and sleep a little longer?”

Su You shook his head: "Brother, I still need to be familiar with the system of the arsenal and the discipline of the shooting range. It's not easy to get out this time. I have to rush back tonight."

After speaking, he turned to Zhao Xu and said, "Brother servant, can you hold on?"

Zhao Xu stretched out his hand and rubbed his face: "No problem! Learn the system first and then enter the factory. You must follow the rules! I understand!"

Su You smiled and said: "Go to the telegraph room first and send a report to the palace that we have arrived successfully. Don't let your grandmother worry."

Zhao Xu nodded: "Yes, let's go see the telegraph room first!"

Arriving at the telegraph room, Su You introduced to Zhao Xu: "This is the first project completed by the School of Physics - a major innovation brought about by the electromagnetic buzzer."

"With the electromagnetic buzzer, you can use the periodic vibration sound principle of the energized electromagnetic coil and magnet to convert the electrical signal into a sound signal, and use short tones to represent zero and long tones to represent one to complete information transmission."

"This reduces the cost of the cable a lot, and at the same time, because of the advantages of sound signals, the speed of transmitting information can be tripled."

"Using new machinery and old lines, our telegraph channel has been expanded four times."

"Now the School of Liberal Arts is compiling a "Dictionary". This book will for the first time use the navy's four-corner number checking method, the rhyme checking method, and the radical checking method. The front part of the dictionary has three checking methods, and it will be marked.

Show the page number of the dictionary where this word is located to facilitate retrieval."

Let Zhao Xu write the message, and then ask him to read the navy code book. The most familiar thing for Zhao Xu is naturally to look up the rhyme table. After finding the code, he converts the message into numbers.

Then the check digit is calculated through an algorithm and turned into a real digital message.

Hand the message to the dispatcher, who puts on the earphones, presses the button, and sends the message out with a beep.

Not long after, a reply came from the telegraph room in the inner palace: "I don't bother to ask questions, I cherish the opportunity, I have so much knowledge."

The message came back very quickly, and Zhao Xu was a sensitive child: "Grandma Huang didn't sleep."

"She is waiting for His Majesty's telegram." Su You said, "She will not rest until she receives His Majesty's telegram."

There is no need for a heavy hammer to play the drum. Su You then said to Shi Tong: "Go to the conference room for training first, and then we will go to the shooting range."

Zhao Xu couldn't train him well, so Su You mainly took him for an "onboarding experience" and mainly explained some safety precautions.

There are many rules in the arsenal. After finishing the lecture, it was already five o'clock. Shi Tong took Zhao Xu, Su You and his entourage to the cafeteria for breakfast.

The main breakfast items in the cafeteria include steamed buns, steamed buns, flower rolls, and fried dough sticks; followed by white porridge, soy milk, and shredded mutton soup; side dishes include kimchi, fried sauerkraut, and stir-fried green vegetables.

When it was almost time to hand over the morning shift, there were already a few early commuters eating breakfast in the cafeteria.

Everyone queued up for breakfast. Zhao Xu was a little hungry after waiting on the train all night. He ate deliciously and raised his head and asked, "Why are the buns here better than... those at home?"

"Not to mention it's true." Su You said with a smile: "Because of the large amount of production here every day, the consumption and production of old noodles have become a perfect cycle, and there are thousands of steamed buns and buns being made every day, and the cooks are

The craftsmanship has also improved rapidly, and with the large amount of residual steam from the steam engine, the steamed buns here are better fermented, seasoned, and cooked than the servants at home, so it’s not surprising.”

After saying that, he took out a small bottle of seasoning from his bag and said, "The hot sauce for the steamed buns, could you please give me some..."

By the time Zhao Xu and Su You had finished their meal, the inner palace squad had already assembled and mounted their tall horses.

The difference between the horse's harness and the ordinary cavalry's is that there is a short leather tube in front of the right leg and a "victory hook" on the side of the saddle. The machine gun is hung on the victory hook, and the holder of the gun is placed in the leather tube and fixed.

Shi Tong introduced: "In the past when the New Army marched, they would carry their magical guns on their backs. Over time, it would consume a lot of physical strength of the soldiers."

"This method is a simulated method of carrying a horse gun, but the foot cover on the horse gun is changed to an independent leather tube, and the rope sheath hanging at the elbow is changed to a winning hook and the connection between the magic weapon belt and the gun body.

Iron ring.”

These were things that Su You had never considered before. To be honest, this was the first time he knew that there were two large and one small rope loops on the horse pole. He couldn't help but nod and praise: "This design is very good, but why don't you use a gun bag?"

Isn't it faster to stick a gun diagonally forward and draw it out to shoot immediately when needed?"

Shi Tong shook his head: "The cost of the leather gun bag used for gun hunting is much higher than the current one. If you use the exposed tube type, the gun weapon and gun bag will easily get stuck during long marches, making it impossible to draw them out.

"

Su You thought about it and it made sense. He smiled at Zhao Xu and said, "Brother servant, you see, true knowledge comes from practice, especially weapons, which must withstand actual testing."

Zhao Xu was impatient with waiting, and hurriedly checked the horse brought by Bian Gu: "Mr. Si, hurry up and set off, it's almost dawn."

Bian Guan helped Zhao Xu check the harness again and nodded to Su You, who smiled and said: "Okay, let's set off then!"

This unit was the first group of troops in the Song Dynasty to be equipped with the machine gun. The machine gun seemed to be similar to the divine machine gun only with the addition of air ducts and mechanical parts, but it actually included a lot of process improvements.

The first is the steel and processing technology. This time, the steel used in the machine gun was improved to a new alloy steel with chromium and nickel added on the basis of the Shenji gun, and the chrome plating process was also used on the inner walls of the bullet chamber and the rifle.

Greatly increases the life of the barrel.

Secondly, precision castings and stamping welding parts were re-used, replacing the cutting technology and precision forging technology brought by Su You to the Song Dynasty.

Su You was very dissatisfied with this at first. He believed that the quasi-constellation, sight base and other parts of the Shenji Gungun were first forged and then machined, or directly processed from bar stock, which was a huge progress of the times.

But the people of the Song Dynasty educated him again. Shi Fu first pointed out that such a processing method was not only cumbersome, but also had low material utilization rate, was time-consuming and material-consuming, and the accuracy was still not improved.

Now that paraffin wax and a large number of petroleum products have been released, casting wax can be prepared. Shi Fu believes that these parts are produced using the lost wax precision casting process. Only a small amount of machining of the parts is required to meet production requirements, which will greatly improve production.

efficiency.

Su You didn't believe it at the time. Wasn't the lost wax method something from a thousand years ago?

But one good thing about Su You is that he understands the rules of science and engineering, and practice is the only criterion for testing truth.

Then give it a try...

So after Shi Tong took over the Songyang Arsenal, just like the Railway Bureau, all technical workers in the factory were actively involved in making suggestions, and we began to vigorously improve the production process of the Shenji Gun.

As a result, countless ideas popped up, making Su You's face swollen.

In the eighth year of Yuanfeng, Shenji Gun has undergone more than 30 technical reforms and upgrades, reducing production costs by one-third, and its durability, reliability, and accuracy have all been improved a lot, and the processing technology has been greatly improved.

The difficulty is greatly reduced.

In this vigorous new technology research and development movement, a large number of technicians and designers emerged from the Songyang Arsenal. In the end, Su You simply asked the arsenal to establish a design bureau under the direct supervision of the Ordnance Supervision to gather these talents.

Improve your salary and specialize in the research and development of new weapons.

Lianjigun's ability to complete the drawing design and product finalization so quickly is closely related to this design bureau.

Compared with the original drawings, the machine guns have also been greatly improved.

The original design of the transmitter base was also die-forged. Because the production process was too complicated, the workers changed it into a steel plate stamping part. The original firing base was divided into two parts: the body and the trigger guard, and then riveted.

The barrel and receiver were previously assembled using threaded connections and tightening. Although the assembly process was relatively simple, due to the high requirements for thread processing and precision, the scrap rate was high and repairs were inconvenient.

Now workers and designers have changed it to a connection method of static pressure fit and fixed pin. The size of the assembly hole on the receiver and the outer diameter of the barrel tail are combined and assembled through the method of optional grouping. After assembly, they are drilled.

Drill the positioning pin into the hole.
