Siheyuan starts from a better life

Chapter 467, New Gun

Time flies so fast, half a month has passed in the blink of an eye.

The production within the institute is proceeding as planned, and new alloys and CNC machine tools are gradually getting on track. Due to the participation of many teachers in the night school, Jiang Yan basically does not need to worry too much.

As soon as he got to work that day, Jiang Yan came to the experimental workshop with the drawings he designed.

On the way to the workshop, Jiang Yan asked his secretary to help him get some special alloy for his own use.

This is Jiang Yan. If it were anyone else to get these alloys, they probably wouldn't give them to him.

Before Jiang Yan arrived at the experimental workshop, the more discerning workers in the experimental workshop saw Jiang Yan, so they hurried to notify Liu Haizhong, the workshop director of the experimental workshop.

When Jiang Yan arrived at the experimental workshop, Liu Haizhong was already waiting at the door of the workshop.

"Old Liu, arrange a workbench for me."

"I understand, Mr. Jiang, make arrangements immediately." After Hai Zhong agreed, he quickly made arrangements for Jiang Yan.

Arriving at the workbench arranged by Bu Liu Haizhong, Jiang Yan took out the drawings he had brought.

He arranged the tools he used neatly one by one, and then checked them from beginning to end to see if there was anything missing.

"Let's try making a pistol this time." After preparing the tools, Jiang Yan opened the drawing and studied the dense lines and annotations for a while.

Jiang Yan carefully looked at the design drawing of the pistol. The size and structure of each component on the design drawing were accurately marked, and some even had three-dimensional assembly diagrams.

He first took out an alloy plate sent by his secretary and carefully traced the shape of the magazine with a paintbrush.

Then start working on the alloy plate. First use an electric saw to roughly cut the shape according to the outline, and then use a lathe to precisely cut each surface. Every step is compared with the drawings frequently for fear of any deviation.

After an hour of careful carving, the first standard bullet clip wall was finally successfully produced.

Jiang Yancheng held it in his hand and checked it repeatedly to make sure that every angle and edge fully met the design requirements, and then he smiled with confidence.

Next, he made a second magazine wall. This one was slightly different from the first one. After the two were made, he clicked them along the concave and convex grooves to form a complete magazine. Then he followed the same method and made three more. Exactly the same magazine.

When Jiang Yan started making it, secretary Xiao Gong, who was standing next to Jiang Yan, roughly guessed what his leader had made, so he quickly ordered Liu Haizhong to find two people in the security department to defend the place.Jiang Yan, who was busy, didn't know yet.

After the magazines were made, Jiang Yan disassembled them and then started making springs. The springs on the magazines and the pistol are called recoil springs.

When the pistol is designed, open the safety, insert the pistol magazine into the magazine of the grip, and pull the slide. Inside the slide is a recoil spring. The recoil spring is sleeved on or under the barrel. When you pull the slide , reach the top of the magazine, and hang the bomb.After letting go, the bullet is driven into the gun chamber by the elastic force of the recoil spring. At this time, the bullet head has been inserted into the bullet inlet of the gun barrel. At this time, the bullet is in the gun chamber. While pulling the sleeve, the hammer is opened. open.When the trigger is pulled, the firing pin quickly hits the primer, igniting the propellant. The high-temperature and high-heat combustion gases are instantly generated. The gas pushes the warhead to rotate through the rifle at an extremely fast speed, making it fly out of the muzzle stably.When the bullet flies out of the muzzle, some of the bullet's gas pushes the sleeve backward due to the reaction force. When it reaches the ejection window, the charging hook hangs on the edge of the bullet case, and the bullet case is thrown away as the second bullet rises. , with the power of the recoil spring, the sleeve brings the second bullet into the gun chamber, and the principle of magazine supply is also based on this.

Soon the two large and four small springs were completed. Put the four small springs in the magazine respectively. This is how to truly make a magazine.

After putting down the magazine, he began to make the barrel. The quality of a gun depends on the quality of the barrel. The use of the barrel is also related to the life of the gun, so this thing cannot be ignored.

To make a qualified gun barrel, you need a high-quality, defect-free steel pipe, which must go through multiple processes before it can be formed. There must be no errors in each process, otherwise the barrel will be a waste product.

Jiang Yan first used a lathe to perform precision turning on the surface of the barrel to create the threads required for the barrel.He then flared and lined one end to ensure the bullet could enter the chamber smoothly.Finally, he electrolytically plated the inner wall of the barrel with chrome to form four right-hand rifling lines.

The threads in the barrel are called rifling, but not all guns have rifling. Those with rifling are called rifled guns. Most modern guns are rifled guns, and those without rifling are smoothbore guns, such as shotguns.

The bullet itself has no threads. When the bullet is pushed to the barrel by gunpowder, the bullet body embeds into the rifling of the barrel. Because of different materials and different hardnesses, the rifling of the barrel will cut threads on the bullet body, which allows The projectiles spin and fly stably in the air, improving shooting accuracy and range. This is what it does.The main purpose of chrome plating the barrel is to form a protective layer on the barrel wall to extend the life of the barrel.

The number of threads to make in the barrel needs to be calculated. It does not mean that the more threads, the better.

The finished gun barrel was carefully put aside by Jiang Yan for backup. Then he started to make the remaining parts of the pistol according to the drawings. Soon, these parts were made by him, and the parts were made. He took a vernier caliper and measured one by one.

The finished parts were assembled like building blocks. The receiver was soon completed. Next, the barrel was inserted into the receiver and assembled perfectly.Seeing them perfectly combined, Jiang Yan couldn't help but smile.

In order to ensure product quality, he will stop and inspect every step he completes to ensure that the manufacturing accuracy of each component meets the design specifications.

Finally, two brand-new silver pistols were assembled and lay on the operating table in front of Jiang Yan.

The appearance of this pistol is silver, with a five-pointed star pattern in the center of the handle. The overall look is somewhat similar to the later Type 64 pistol, but its appearance is much more compact and slightly larger than the later Type 64 pistol. Quite beautiful.

After the pistol was assembled, his secretary Xiao Gong's eyes never left it. This was not a murder weapon, but a perfect handicraft.

Jiang Yan was quite satisfied when he saw the pistol he had made. He picked it up excitedly and tried to make a shooting posture. After getting excited, he weighed it in his hands. The familiar texture and weight made him very satisfied. .

After getting the pistol, Jiang Yan was happy, but he also discovered a problem - there were no bullets to test-fire the new gun.

He frowned and thought for a while, and suddenly his eyes lit up - the military representative room! He could go to them and ask them to get some bullets for him. With the appearance of the pistol he designed, they would definitely be happy.

Thinking of this, Jiang Yan directly put the two pistols in his trouser pockets, one on the left and the other on the right, and said to his secretary Xiao Gong: "Pack the drawings away, let's go to the military representative's office."

So, Jiang Yan took his secretary to the military representative's office and knocked gently on the door.

"Please come in." The voice of military representative Shen Chong came from inside.

Jiang Yan pushed the door open and walked in. Shen Chong, who was working on documents, saw Jiang Yan and stood up quickly. Then he quickly said: "Mr. Jiang, you are here. I don't know if you need my help with anything."

"Xiao Shen, I have a new invention here. I need your help to test it. Please help me." Jiang Yan said his intention straight to the point.

"New invention?" Shen Chong was a little confused.

The next thing he saw, Jiang Yan took out two beautiful pistols that he had never seen before from his pants pocket and put them on the table.
"This, this is..." Shen Chong's eyes widened and he pointed tremblingly at the two pistols on the table, speechless.

"Mr. Jiang, did you do this?" Shen Chong swallowed hard when he said this.

"Yes, I did it, but now there is a problem."

"Whatever problem, as long as I can solve it, I will solve it." Shen Chong answered with certainty while looking at the pistol on the seat.

"The gun has been designed, but it cannot be tested without bullets." Jiang Yan said

"What caliber of bullets do you need? I'll take care of it."

As soon as Jiang Yan heard this, he asked his secretary Xiao Gong to bring out the bullet drawings he designed and explained them in detail.

Hearing the new bullets and looking at the new guns on the table, Shen Chong believed what his leader said when he came here before, and he also understood why military representatives were set up here. This is so unexpected, okay?
