Embodiment Construction

[0034] This technical scheme should preliminarily process the bullet chamber before processing the rifle.

[0035] High-strength carbide rifling with specified structure can be produced by hot rolling in batches according to design.

[0036] How to embed high-strength rifling into the smooth bore barrel to melt and bond the two materials: design a special high-frequency electric furnace, and use induction heating to soften the smooth bore barrel; put the required number of rifling into the smooth bore . Obviously, the rifling material to be used in this technical solution can still maintain the proper hardness at the temperature at which the smooth bore matrix material is heated and softened; the rifling is inserted into the guide groove of the "special lead male die", and the male lead is driven by a pull rod or a push rod. The mold precesses, so that the rifling is strongly crushed and pressed into the barrel matrix. Because the yin and yang lines of the male mold itself h...

Abstract

The present invention is used in rifling weapon and has the technological feature that the rifle material dissimilar to that of gun barrel is hard alloy with high hardness at high temperature, high wear resistance and high toughness at high temperature, and is first rolled into rifle and then embedded into gun barrel to form high strength and long life smooth rifle. The wear resistance of rifle is essential to the performance and service life of weapon, and the technology of the present invention can solve the problem of short life radically. The present invention may be used in raise performance of weapons greatly.

Description

technical field [0001] The invention relates to the industrial production of weapons, and relates to the rifling processing technology required for the manufacture of barrel-launched weapons (cannons and large-caliber firearms). It belongs to the technical field of IPC "International Patent Classification" - "B21" (basically non-cutting metal machining) and "F41" (arms). Background technique [0002] Military power is the guarantee of national security. Weapons have always been an important foundation of military power, and they also occupy and consume a large amount of national resources. Undoubtedly, efforts should be made to improve the technical indicators of the weapon system, so that it can be produced and operated with high efficiency and low consumption, which is conducive to saving resources and may also store more strategic materials. While developing and manufacturing high-tech weapons, it is still of great significance to develop and maintain conventional weapo...
