Chapter 651 Brand new machine gun

Previous page        Return to Catalog        Next page

    In later generations, the chrome plating process has become very popular. Even if it is a piece of plastic, the surface can be plated with chrome, and it looks fluorescent, just like metal. Now, the chrome plating process is regarded as high-end.

    "We can only use the most basic method, that is, the chromium plating solution with sulfate as the catalyst. The plating solution contains chromic anhydride and sulfuric acid, with simple ingredients and easy proportioning. It is also the most commonly used chromium plating solution in the current technical field."

    In a blink of an eye, he has come to a special chrome-plating workshop for gun barrels. After entering this workshop, he can smell the pungent and pungent smell, which makes Qin Baoshan have an urge to wear a gas mask.

    The electroplating pool is not big, just a small water tank, just enough to put the gun barrel in it, and then the gun barrel is connected to one electrode, and the metal chrome is connected to the other electrode.  The metal chrome rod is directly plugged into the inside of the barrel, so the metal chrome is plated on the inside of the barrel.

    "Through our similar experiments, a low-concentration electroplating solution is the most suitable, but the required voltage is higher. At present, the main factor restricting our electroplating gun barrels is the power supply problem." Lu Da introduced.

    The concentration of this electroplating solution is different. The low-concentration chromium plating solution has high current efficiency and high hardness of the chromium layer, but the coverage is poor. Because of the poor coverage, if you want to form a thick enough chromium layer, you need to lengthen  Plating time, thus consuming more power.  This method is mainly used for hard chrome plating, wear-resistant chrome, etc.

    However, the high-concentration plating solution is stable, has good conductivity and strong covering ability, and can complete electroplating on workpieces with various complex surfaces. It is mainly used for decorative chrome plating and chrome plating of complex parts.

    Now, they have studied repeatedly and finally found the most suitable process.

    "The electroplating solution and metal chromium rods were purchased through the Soviet Union." It seems that Qin Baoshan is very concerned about this issue, Lu Da said.

    These things cannot be produced in the base areas of the Eighth Route Army, and there is no way to seize them, because the devils don¡¯t have them, and they are in the devil¡¯s homeland, so the only way is to buy them. As long as they can be bought, they are good.

    Qin Baoshan nodded: "Yes, as long as the problem can be solved."

    "The superior's opinion is that they want to use this technology to produce machine guns to meet the firepower needs of the troops." Lu Da continued to say to Qin Baoshan.

    Ordinary Bayi-style rifles do not need chrome plating, or the need is not urgent. After all, ordinary rifles do not have many chances to fire bullets.  The supply has kept up. After a battle, ordinary soldiers can only fire ten or twenty rounds of ammunition at most. The current barrel has a lifespan of several hundred rounds, which is also possible.

    However, machine guns are different. This chrome-plating process is mainly prepared for automatic weapons. The firepower density of the Eighth Route Army is far inferior to that of the enemy on the opposite side. If a batch of machine guns are produced, it can effectively improve  The army fires up.

    "Machine gun?" Hearing this, Qin Baoshan's eyes lit up immediately: "Why do you want a machine gun? Isn't our assault rifle a machine gun?"

    So far, assault rifles are still produced and tested in small batches. It is impossible for a new weapon to be put into mass production as soon as it comes up.

    After using it for more than half a year, all fighters who own it can't put it down. The weapon's firepower is fierce, and they are full of confidence when charging!  If a platoon is equipped with this kind of weapon, its firepower can catch up with a battalion!

    The extensive use of assault rifles is simply a change in the way infantry fights. Just look at later generations and you will know that assault rifles have long replaced ordinary bolt-action rifles. The ancient bolt-action rifles are only used in military parades.  will be used.

    Now, the superior had the idea of ????needing a machine gun, and Qin Baoshan immediately reacted. Why do you need a machine gun?  Our assault rifle is a machine gun!

    "First of all, in terms of ammunition supplies, let's turn the current 30-round magazine into a drum with 75 bullets." Qin Baoshan became interested again when he talked about this: "Other organizations don't use  Change, as for the barrel, the barrel of the machine gun needs to be longer and thicker, so that a family of guns can be formed."

    The concept of the gun family is very popular in later generations. A rifle must have an assault rifle, a machine gun, and a semi-automatic sniper rifle to form a complete gun family. Many parts are interchangeable.  , is also convenient to use.

    Now there is just this opportunity to expand the current equipment sequence, and when it is used more in the future, it will naturally be expanded.

    "A brand new machine gun?" Xiong Zheng opened his eyes wide.

    See Qin Baoshan's design with my own eyes.??When the rocket launcher came, Xiong Zheng was surprised at the time, but now, he saw a miracle again, a brand new machine gun!

    It is very difficult to develop a new type of machine gun. At present, the most used machine guns in China are the Czech-made machine guns and the crooked handles of the devils. Because the devils dislike the crooked handles and are not easy to use, they even follow the style of the Czech-made machine guns.  , The devil's 96-type light machine gun was transformed.  It can be seen that even devils can't play with the new design of light machine guns.

    What about Qin Baoshan?  In this way, a brand new machine gun was created!  On the basis of the assault rifle, after modification and strengthening, it becomes a machine gun.

    Xiong Zheng admired it immensely.

    "But, is this appropriate? Machine guns use such intermediate-power bullets?" Lu Da hesitated.  After coming here for a long time, I have a deeper understanding of that assault rifle. I already know that the characteristic of that assault rifle lies in the change of bullets.

    "This is more appropriate." Qin Baoshan said: "As far as our army is concerned, the current combat distance is one or two hundred meters. After adding a long barrel, this kind of machine gun is an absolute weapon within three hundred meters. As for  Enemies at farther distances have our bolt-action rifles! Without further ado, I decided to do it now!"

    Do it now?

    Qin Baoshan is really a man of hard work, he will do what he says.

    The design of the barrel is not complicated, it¡¯s just thickened and lengthened, the main thing is the drum, which needs to be redesigned according to the volume of the bullet, so Qin Baoshan lay down on the table and began to do various calculations.

    Qin Baoshan's confidence is full, after all, this is a trend of later generations!  The idea of ??the superiors is probably to imitate the Czech-made ones. The Czech-made ones with only 30 rounds of magazines are really outdated.  Since I am here, of course I have to make a brand new one.

    The night is getting darker.  (Remember the site URL: www.hlnovel.com
