Thank you also to other brothers for their monthly votes! ! ! ! ! ! Baozi still needs monthly support from brothers, please vote for me! ! ! ! ! ! ! ¡ª¡ª ¡ª¡ª It wasn't until Chen Er was busy for more than an hour that Li Jun woke up rubbing his head. He came over and said to Chen Er while putting on his clothes: "Second brother, you got up too early. The Soviet wine that Lao Maozi drank yesterday was really strong. My head is still a little dizzy now." }{}How do I look at you as if nothing happened? You obviously drank yesterday. How can you be a better drinker than me? It¡¯s so unreasonable. " This is what Li Jun said. I took the washbasin and prepared to go out to wash my face and brush my teeth. People in this period are still very particular about their personal hygiene. Although they can't take a bath every day, they will never miss washing their face and brushing their teeth sooner or later. Seeing Li Jun wandering away, Chen Ercai smiled. Comparing your drinking capacity with yourself is not asking for abuse, but Chen Er is also a little curious. The only thing he has traveled through time is his consciousness, and this body still belongs to the original owner. Even if he could drink before, he couldn't bring him here. After thinking for a long time, Chen Er couldn't come up with a reason. In the end, he could only attribute it to the large military industry system. Such high technology might also be able to relieve hangovers. What's the role? Anyway, no one can say for sure. By the time Li Jun appeared in front of Chen Er again, it was already half an hour later. It was unclear whether these boys had gone out to brush their teeth and wash their faces. Or go and do something else. Li Jun looked at the drawings on the table and asked: "Second brother, isn't this the semi-automatic rifle drawing we developed before. Don't you think it's enough to just make a few changes?" Li Jun's eyes widened like a Ling Ding looked absolutely disbelieving. Chen Er didn't know how to explain it to him. He could only say: "This is almost what you said, but there are a lot of things that need to be changed. I have only completed less than half of it. I guess I will be busy today." That's about it for the last day. Maybe I don't have time to walk around with you today, so you can arrange your own time for today." After saying that, Chen Er began to concentrate on revising the drawings. ?????We are very familiar with 501 Li Jun. He has no place to go alone, so he can't go to Wen Jing's dormitory again. Think about it. Li Jun resolutely decided to stay with Chen Er. He could still learn something, which was better than running around by himself. So Chen Er changed the picture, and Li Jun watched carefully. Of course, he was also responsible for serving tea and water. The morning passed quickly. Chen Er stood up and stretched. He could finally take a rest. He didn't even bother to wash his face when he got up today. Li Jun also said with great admiration: "Second brother, your drawing is simply too good. There is no trace of any changes at all. At first glance, it looks like it was printed by a machine. It seems that it is being made. I really have to work hard on drawings, otherwise I won't even have the chance to be your assistant in the future." Of course Chen Er could hear the exaggeration in Li Jun's words. Hand-painted drawings can never match the accuracy of machines. of. It¡¯s just talk. At noon, I went to the cafeteria for lunch and then came back to get busy. As expected, it was pretty much what Chen Er expected. At around four o'clock in the afternoon, I finally finished changing the last drawing. All the drawings of the Type 56 light machine gun are on the table. After Chen Er put all the drawings in order one by one, he finally smiled. This is considered completely done. It can be regarded as the fastest masterpiece I have completed. The next step is the production process. Chen Er is going to hand over the drawings to the master tomorrow. Of course, I will also participate in the production of firearms. After completing the Type 56 light machine gun, I can become a third-level military industry. I wonder what surprises the large military industry system will bring to me. At this time, Chen Er couldn't help but recall the various data and structure of the Type 56 light machine gun in his mind to facilitate tomorrow's production. The Type 56 light machine gun is a 7.62 mm caliber light machine gun designed and manufactured by our country's working class and scientific and technical personnel in 1956 in accordance with the Communist Party's teachings on independence and self-reliance. Because the Type 56 light machine gun is basically equipped at the squad level, it is also called the Type 56 squad machine gun. The Type 56 squad machine gun is the main firepower weapon in infantry detachment battles. It has the best shooting effect on a single target within 500 meters. The concentrated firepower can shoot enemies and paratroopers within 500 meters; it can kill group targets within 800 meters. The warhead is still effective within 1500 meters. The lethality is mainly implemented in short bursts (2-3 rounds), long bursts (6-10 rounds), and continuous firing if necessary. After firing 300 rounds of bullets continuously,??Cool the barrel. Using Type 56 ordinary ammunition, at a distance of 100 meters, it can penetrate 6 mm thick steel plates, 15 cm thick brick walls, 30 cm thick soil layers and 40-60 cm thick wooden boards. It can be said that it is already powerful in terms of power. It has reached a very high level, which is why it has been used for more than 30 years. The Type 56 squad machine gun is mainly composed of ten parts, each part has its own independent function. The barrel is assigned to the flight direction of the warhead. Inside the barrel is the barrel. The barrel is divided into a cartridge chamber and a rifling. The cartridge chamber is used to accommodate the bullet. The rifling allows the warhead to rotate as it advances. to maintain flight stability. There is an air guide tube outside the barrel to accommodate a gas regulator to guide the gunpowder gas to impact the piston. The gas regulator is used to adjust the size of the gunpowder gas to impact the piston. There are three air guide grooves and three gaps on the gas regulator, and the numbers 1.2.3 are listed side by side, indicating the small, medium and large air guide grooves in order. Usually set at 2, under severe cold conditions. Set it to 3 when the shooting or moving parts are too dirty and there is no time to wipe them. in hot conditions. When the force of shooting or bolt retreat is too large, it is set to 1. There are also connecting tubes, piston barrels and handguards outside the barrel. The sight consists of a red plate with a laser mark and a horizontal scale, with long divisions from 1 to 10 arranged side by side. Each long division corresponds to 100 meters. There is a short division between the two long divisions. Each short division Corresponding to 50 meters, the back of the scale plate is also engraved with long divisions to facilitate the installation of the scale. There are wheels and gaps on the horizontal scale to correct the direction. There are 7 reticles engraved around 0. Each reticle moved is equivalent to the aiming point moving 20 cm at a distance of 100 meters, 40 cm at 200 meters, and so on. The front sight can be screwed up and down, and the front sight movable base can be moved left and right. There is an engraved line on the front sight movable base to check whether the position is accurate. There are divisions on the front sight constellation. The width of each division is 1 mm, which is used to effectively determine the momentum of the front sight. The receiver is used to accommodate the bolt, ensuring that the bolt locks the gun chamber, and there is a cover outside the receiver. It is used to cover the receiver and accommodate the trigger. The connecting groove and connecting pin are used to connect the trigger and the butt to the receiver. Connecting plate and wrench to connect and secure the magazine. There is a locking slot in the receiver. The shell is pushed out and the bamboo shoots are stuck in the slot. The bomb receiving machine consists of the bomb receiving machine base, the bomb receiving machine frame and the bomb receiving machine. Used to deliver bullets. The bullet-receiving machine base is used to place the ammunition belt and ensure its smooth passage. The bomb-receiving machine base has: bullet-blocking teeth to prevent the ammunition belt from falling off, and depressing teeth to press the bullet and keep the bullet from the ammunition belt. separate. The bullet receiving frame is used to regulate the movement of the bullet slide. The detaching machine consists of a detaching slide and a long and short detaching arm. Under the action of the machine frame pulley, the bullets on the ammunition belt are sent to the receiving machine. The bolt action is composed of a machine frame, a body and a gun handle. It is used to feed bullets, lock the fire, eject the shell and drive the movement of the bullet pulling machine. There is a piston on the machine frame to withstand the pressure of gunpowder gas and push the machine frame backward. There are also shaped grooves, supports, firing sear grooves, pulleys and round nests on the machine frame. The body has a firing pin, a bullet catching hook, a long locking iron and a shaped protrusion. There is a hook on the machine handle to pull the machine frame to the right. The retractor is used to return the bolt to the forward position. The firing mechanism is composed of a firing frame, a firing sear, a trigger and a safety mechanism. It interacts with the bolt to make it ready and fired. When the safety mechanism is pulled forward, it is safe. The butt is easy to operate and has a recoil mechanism nest and accessory box nest inside the gun butt. The tripod is used to support the machine gun. The magazine is used to hold bullets. There are 2 or 4 sections of ammunition belts in the magazine, which can hold 100 rounds. The magazine has a hook, a lifting ring, a cover plate and a cover buckle. These information flashed through Chen Er's mind quickly. He now has a better understanding of the Type 56 squad machine gun. If he encounters any difficulties during production tomorrow, Chen Er will be able to solve them in time. And the most important thing is that Chen Er is not going to take the credit, and just regard it as a gift to the master. Anyway, I came here empty-handed this time, and nothing seemed to make the master happier than this. Seeing that Chen Er had finally called it a day, Li Jun also said cheerfully: "Second brother, you can tell the master about your marriage this time. You can't be careless about your marriage. You must make it a glamorous one when the time comes." "Yes, how about I come and plan it for you myself?" Chen Er smiled nonchalantly. That's how it is in this era. Li Jun can't do any tricks in planning. You can't expect this kid to conjure up a wedding dress. . ¡°Besides, even if Chen Er really managed to get a wedding dress, Murong Wan would not dare to wear it. This era is not that open. Unlike girls in the 21st century, as long as the most important part is covered, there seems to be nothing they dare not wear. This is a big difference. Chen Er thought for a while and said: "I think this is it. Let's make this light machine gun tomorrow. Let's gather the strength of the whole factory and we can complete it in one day. After that, I will mention my marriage to the master. This is also It¡¯s a double happiness, what do you think?¡± ¡°What can Li Jun have to say? It¡¯s Chen Er getting married anyway,¡±If you're not in a hurry, you don't need to worry about it. The two of them laughed and chatted about other things, and it was time for dinner again. Time always flies when I'm working, and just like that, another day passes. Thinking about it, it seems that nothing has been done. Life is like this, time flies, and people get old in a blink of an eye. If you don't cherish the present, you will definitely regret it one day. Chen Er lives with this kind of mood now. Living every day to the fullest is his biggest goal. Thinking about it, Murong Wan and Chen Er also felt very happy. For young people of their generation, marriage already advocates freedom. However, due to the reputation of men and women, most of them still fall into the category of getting married first and falling in love later. There are really not many like them. Of course, getting married first and then falling in love also has certain benefits, that is, it further tempers the personalities of two people, and some bad habits will be slowly corrected in daily interactions. And because of people's concepts in this era, divorce rarely occurs, and naturally there won't be so many single-parent families. As an orphan, Chen Er still appreciates this point. In this regard, it is much better than modern society. (To be continued, please search Piaotian Literature. The novels will be better and updated faster!
