Description of the invention: [Technical field to which the invention pertains] The present invention relates to a sub-arm of a weapon and a method of manufacturing the same, and more particularly, to the method and method, wherein the bullet (four) is a chess shape, and There is a body that is preferably formed from a single piece of metal. [Prior Art] 1 The magazine is used to hold ammunition, for example, a series of bullets, which are carried out by the more means of the bombs - the secondary feed - in the launch room of the weapon. This elastic means maintains the pressure on the ammunition to force each g-bomb into the firing chamber, and § delivers the next bullet to the launch position when the firing is completed. An example of a weapon that uses the g-g is the M16 rifle or carbine, which has become the standard step in the US weapons arsenal and other Western destinations. (iv) There are many variants in the weapons series, such as: M16/A1, A2, A3, and A4, XI, which are the main infantry rifles used by the US military and 15 NATO countries since the early 1960s. . These weapons use the type of the craftsman disclosed in the present invention. Preferably, such magazines have an arched shape and have a substantially rectangular cross section with two parallel faces facing each other. The long side defined by the height of the body, and the body is disposed between two parallel opposing short sides defined by its width. One end of the magazine is closed by a removable bottom plate And the other end is open to allow a body that is in a juxtaposed position with the weapon launching chamber to be placed in the firing position. Preferably, the magazine is made of steel, not plastic or aluminum. This is because when the magazine is used on the battlefield, it suffers from heat and considerable stress. 97112120 200905153 Usually, as in the case of the M16 Carbine series, this type can be loaded with 30 bullets' It weighs approximately 18 ounces at full time. Such a magazine® must be nested in the lower container located on the underside of the weapon, and, in order not to interfere with the operation of the weapon, preferably, the bullet line is inserted relative to the body. Preferably, this is hiding Wherein there is formed a thinner side ^ a keyway for aligning and oriented in an appropriate PCT body hair

U.S. Patent No. 4,514,922 to Lal., et al., which is incorporated herein by reference. 7, US Patent No. 彻, ru, No. 252, reveals that it is used to hide the initial structure. These reference documents cover a variety of long-term various types of magazines, and they are produced, but they are not taught to be used in: 1. The difficult structure and method of the present invention are It is almost := when used, and this is the most reliable on the battlefield. The 5th eve of the prior art is only for hand grabbing magazines, and these magazines are not typically used for rifling or carbine robbing. They are subject to severe battlefield pressure and situation. 'User life and weapons are effective. Sex is closely related. The light-known research data for the use of the brown gun and the carbene robbing shows that the high failure rate of the conventional bomb E, sometimes even as high as 50% or more, is that the bomb of the embodiment of the present invention is displayed after research. Almost no fault. SUMMARY OF THE INVENTION The arched device of the embodiment is very sturdy and made of steel to withstand the pressure of the battlefield and has a smooth keyway and interior to allow the bullet to freely break from the magazine into the firing chamber of the weapon. These characteristics are achieved by the use of manufacturing means that eliminates the enemies and coarse recordings in the bullet g, and the selection of joints that do not allow the H (four) mechanism to interfere with the movement of the projectile. In the disclosed method, the blank body is made of high carbon steel (preferably having a hardness of 34 to 38 RC Rockwell), so that the block is not too easily bent. However, it is not too hard and the material is fragile. This bullet E (four) is designed to require only a single seam to form a pattern, so that the keyway will not have solder joints, sensitization, or the like. This type of manufacturing requires metal extrusion operations, drawing in a single operation and forming a magazine containing a keyway, preferably using a 6-ton press (but a smaller press can also be used). There is an upper pressure pad provided with a male form arbor, and a top male forming block and a bottom mother forming block. The top male forming core f is pressed downward by a pressure of about 5 _ _ 吋 ( SI P P 被 被 被 被 被 被 被 被 被 被 ' ' ' 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母 母_arbor) is responsive to a downward pull motion with a pressure of approximately 9 watts per square lb (lbs. psi), thereby forming the keyway and one of the short sides of the bridge of the E. The two lower pressure pads are also used as curved surfaces. When the blank is drawn downward between the lower pressure jaws, the system is formed across the surface of the wire. If the application is not enough, the keyway cannot be formed. If the pressure is too large, the metal will tear. Preferably, the male core has a plurality of introducers (p; 1〇t) for positioning the viewing aperture on the side of the curve of the bomb. Preferably, these guide holes function to maintain the body in place during the drawing and forming operations and wiping operas. Preferably, the edges of the formed body placed on the keyway are used to weld the closed (four) body by one or more additional solder joints, but the position of the solder joint can still be in any position 'as long as it does not interfere It is only to the keyway, and it does not cause enemies or rough surfaces inside the bomb E when it is formed. The drawing and forming operations produce a U-shaped body E that is oriented such that the keyway forms the bottom of the chevron.
