The origin of "crooked name" In fact, many people are wondering why there is such a vulgar name since it is a machine gun. And this needs to start with the design of the curved handle. 1904, Japan and Russia confronted each other. At that time, Japan and Russia violently attacked the land over China in the three northeastern provinces of China. Although the war ended in Japan's victory, Japan also entered the ranks of imperialism because of this battle. However, the loss of Japan in this World War I was not great. Because they saw the destructive power of machine guns on infantry regiments in this war, and Japan was weak in the level of machine guns, they prepared to develop a machine gun of their own.
Unfortunately, due to the lack of work experience in these areas, the machine guns developed by science are a bit weird. Japan itself is a country with weak resources, and machine guns are not excluded. At that time, in order to save resources better, five magazines like automatic riflemen were selected for ammunition supply, but in this way, the soldiers' sight was blocked when they were watching. In order to better handle this scheme, the handle was turned to the right under the design scheme.
The designer thinks that this method can fill this deficiency, but in the whole process of specific shooting, the barrel and grip of the "slanting machine gun" are not on a parallel line, and the result is that it looks strange, so everyone called this Japanese machine gun "slanting machine gun" at that time.
When the Type 62 machine gun came out, it was said that after the withdrawal of Japanese troops in World War II, all the weapons were destroyed, and the US Army was solely responsible for docking. However, when the US military first started to do social security in Japan, it was very refreshing to give it away for nothing, but it was also annoying to have too many things. So at 1950, at the behest of the US military, a China police reserve and a set of American weapons and equipment were assembled. By 1954, foreigners thought that it was not easy for the Japanese to come up with any bad ideas, and once again allowed the Japanese to form the monsoon paddy field agricultural self-defense force. The Japanese have a regular army, and then the question comes. What should I do with this gun?
At that time, all the weapons and equipment they had were American Army's M/KOOC-0/galante/Cabin Bar/KOOC-0/928A2 sniper rifle M/KOOC-0/9/KOOC-0/9A4/A6 machine guns, especially BABA and M/KOOC-0/9/KOOC-0/9, which were very backward in World War II. In addition, after the war, all countries in the world are learning the Italian definition of general machine guns, so there is no doubt that the Japanese have to follow suit. Therefore, Masami Kawamura, the gun interior designer of the Japanese metal material industry manufacturer at that time, gradually developed products in the same year.
1956, the prototype of type 62 machine gun came out (they called it the trial model of 3 1 year). Does this thing remind you of anything in the picture? Yes, to put it bluntly, the prototype of the 62-way machine is that the Japanese changed the 99-type light machine gun into a bullet chain. Naturally, this kind of personal behavior must be the "Red Deer and Wild Lang" of the Self-Defense Force. Everything will be slightly normal after the trial production at 1960.
In the process of 1962, of course, the 7.62x5 1mm automatic rifle ammunition of NATO member countries was distributed, but the Self-Defense Force chose the reduced load version, but standard ammunition can also be distributed. Type 62 machine gun is a long-stroke machine gun, and its basic principle is that the piston rod guides air. Originally, I thought it was locked like the 99-type, but after looking for a Japanese picture book, I found that the bolt was offset, which was a little ignorant.
First of all, let's look at the shortcomings of the Type 62 machine gun. As a universal machine gun, does your barrel look a little weak? Yes, Kawamura Masami was thinking about reducing the fat of the machine at that time, so the design of the barrel wall and the chamber wall was very thin. This thinness leads to two problems. One is that the barrel vibrates greatly during continuous shooting, and the dispersion increases accordingly. The other is the poor heat capacity of thin-walled cylinder. If the barrel is overheated too early, it will change the original vibration frequency and further endanger the accuracy.
In addition, if the hole wall is too thin, the shell jam will be aggravated, and the shell is not easy to pull out after being fired. Generally speaking, it is difficult or inconvenient to brush oil, or it is inconvenient to carve grooves on the inner wall of the bore like G3, so that gunpowder natural gas can arrange air cushion cc in the middle of the bore. However, Kawamura Yami is different. It uses too many air inlets, and according to the method of increasing air outlets, it creates enough momentum and torque in the back seat to pull the shell out.
Needless to say, this shell-pulling ability is not easy to break (it is said that it has a set of system software to slow down the engine shell-pulling rate and avoid shell-pulling problems), but the back seat speed of all the racks is very fast, which leads to the thick chassis to maintain sufficient compressive strength. Boy, the net weight saved from the bucket is equivalent to adding it to the box.
Its anti-hook (iron resistance), at the end of the casing, is also a very dual design scheme. Type 62, as a kind of machine gun with its belly cut open, has to loosen the bolt if it wants to stop fighting in automatic shooting, and then the iron block is tilted and hooked on the frame. Generally speaking, the stop iron should be placed in the front part, so as to ensure that the frame will be hooked when re-entering. However, if it is too far back, it is very likely that the frame will "miss" the iron block when the back seat is not timely, or it is very likely that when the bottom of the box is violently hit, the frame will not be able to catch the iron block because of vibration, resulting in the common problem that the gun can't stop fighting even if it is loosened.
So to sum up the problems of this gun, the main ones are:
1, the wall is too thin, and the heat capacity and accuracy are poor.
2. Because the bore wall is too thin, it is easy to overheat, which will cause the shell to stick to the bore. Moreover, excessive air intake and a set of complex shell pulling deceleration mechanism are needed to avoid the problem of shell pulling.
3. Excessive air intake leads to large recoil of the machine frame, and the shell wall needs to be strengthened, resulting in white weight loss of the gun barrel.
4, the tail trigger resistance iron may lead to playing without stopping.
