The barrel was cast by casting method in the past, but now the barrel is directly drilled on the iron rod and rifled.
Many military enthusiasts are very curious about the production process of the barrel, because there is no weld on the outside of the barrel, they just want to know how the barrel is produced? Let’s learn about it.
Details
01
Barrel refers to the surface of the barrel between two sights on a firearm, divided into a smooth barrel and a rifled barrel. The barrel is one of the main components of a firearm, usually made of a heat-resistant, non-deformable metal tube that is attached to the chamber. When a bullet is fired, the expanding gas produced by the explosion of the gunpowder or the pressure of the air, or other power, will push the bullet through the barrel, and eventually become a high-speed projectile.
02
As the main part of bullet acceleration and rotation, the barrel should not only have a strong impact resistance, but also have a very smooth interior, which is indispensable, especially the smoothnes
03
Cast out of the barrel, although the impact resistant ability, but its internal smoothness is very difficult to guarantee.
04
The gun made by casting has another disadvantage, that is, it is very heavy.For any soldier, when fighting, in addition to carrying firearms, he will carry other necessary items.Therefore, the forged gun will invisibly increase the weight of the soldier.
05
When the barrel is made, it is an iron rod. The worker drilled the hole in the middle of the iron rod according to the relevant parameters of the firearm being built. Thus, while the barrel was made, the rifles were made.
