Definitions
- the invention relates to a method for producing a deformation shell, consisting of a bullet core of lead in a Tombakmantel.
- the invention has for its object to provide a method for producing a deformation projectile, with which the performance of the projectile, such as precision, deformation and energy transfer in the target medium can be set.
- a homogeneous bullet core is to be created, the structure of which includes a "predetermined breaking point" in the central axis of the projectile.
- the production of the bonded blank takes place consisting of a bullet core made of lead in a tombak jacket.
- a firm connection is made between the lead core, or the core of the bullet and the tomban jacket. With bonding is always meant soldering.
- the introduction of a pre-damage into the lead of the blank is carried out by pressing a displaceable on the central axis of the blank punch in the lead and remove the punch again.
- this preliminary damage parameters: depth, diameter, shape of the punch
- the deformation capacity of the projectile is determined. Furthermore, will be
- the final pressing of the blank takes place in the final shape of the deformation bullet with outer longitudinal grooves on the ogive and a rear inner cone, wherein the final pressing a pressing force greater than 7,000 N ver - is used.
- the pressure exerted influences the flow of the lead. The higher the force, the further the lead is beyond the edge of the mantle. Weapon function and deformation behavior are influenced by this "lead edge.”
- the pressing step carried out in the second process stage b produces the preliminary damage by creating a cavity in the lead core or in the projectile core.
- This two-stage process results in a homogeneous core with a microstructure in the central axis of the bullet, which achieves homogeneity at a pressing force of 7000 N.
- the pressing force typically between 10,000 N and 30,000 N
- the lead will be different pressed far into the nose of the bullet.
- a lead made of CuZn3-CuZn15 is used as lead and lead as Tombakmantel.
- a cylindrical punch having a front tip is preferably used.
- the following parameters a Depth, number, length of the outer longitudinal grooves on the ogive
- Press force when pressing the final shape of the deformation bullet set the precision and effect of the bullet.
- a rear inner cone has been formed in the projectile. The selected shape of the projectile tail with the rear-inner cone serves to optimize the core compression and improves the precision of the projectile.
- a deformation projectile according to the invention with a bullet core made of lead in a tombak jacket, with outer longitudinal grooves on the ogive and with a rear inner cone produced by the method just described, is characterized by a homogeneous projectile core whose structure in the center axis of the projectile is a predetermined breaking point includes.
- the invention describes a bonded (soldered) deformation bullet 1, preferably in the caliber 9 mm, consisting of the combination of pure lead, which is soldered in a Tombakmantel (CuZn3 - CuZn15).
- the production process of the projectile is conducted in at least three stages. By combining these production steps and their parameters, the performance of the projectile, such as precision, deformation and energy transfer in the target medium, are set.
- the first manufacturing stage is the production of the bonded blank 4.
- a firm connection between the lead core and Tombakmantel 4 is made.
- Figure 1 shows a bonded blank 4, consisting of the Tombakmantel 4 and arranged in Tombakmantel 4 lead core or lead 9, which is soldered to the Tombakmantel 4.
- Figure 2 shows the bonded blank with pre-damage introduced according to Figure 1.
- a cylindrical punch 10 with a front tip 11 was inserted into the lead Lead 9 pressed and after the
- the deformation capacity of the projectile 1 is determined. Furthermore, air pockets that are formed during bonding are reduced. With bonding is always meant soldering.
- the third method step see FIG. 3, the final shape of the projectile 1 is pressed with the outer longitudinal grooves 5 of the ogive and with a rear inner cone 6. This manufacturing step can also be broken down into sub-steps.
- the pressure exerted influences the flow of the lead. The higher the force, the further the lead is beyond the edge of the mantle.
- Figure 4 shows a finished deformation bullet 1 in section, in which worked with a large pressing force. Significantly, the lead edge 8 can be seen. In the finished bullet a rear inner cone 6 has been pressed.
- Figure 5 shows a finished deformation bullet 1 in section, in which worked with a smaller pressing force. There is no lead sand available.
- FIG. 6 shows a bonded deformation bullet 1 according to the invention after soft target firing.
- the Tombakmantel 3 has not detached from the bullet core or lead core. However, the Tombakmantel 3 is mushroomed. From Tombakmantel 3 no parts have been solved.
- the invention thus describes a deformation projectile in which the precision and effect of the projectile is set by the combination of the abovementioned three features.
- this combinatorics is shown on a 9 mm pistol bullet. bonding process
- the variation of the shell wall thickness can also influence the target ballistic effect.
- the cavity in the lead core (see FIG. 2) inserted in a first pressing step, introducing the pre-damage, is closed again during final pressing (see FIGS. 4 and 5) of the projectile.
- This two - stage process results in a homogeneous projectile core whose structure is in the middle axis of the Homogeneity is achieved at a pressing force of about 7,000 N.
- the pressing force typically between 10,000 N and 30,000 N
- the lead is pressed into the projectile nose to different extents.
- FIGS. 7 show four deformation projectiles 1 according to the invention after final pressing as a top view from above of the ogive. These bullets differ from each other only by the force used in the final pressing.
- FIGS. 8 a, b, c, d show the same four deformation projectiles according to the invention after final pressing as FIG. 7, seen only laterally from above. In all figures, the different tips of the Ogiven are clearly visible.
- FIG. 9a shows the projectile casing and FIG. 9b shows the lead core, each in section.
- bullet jacket or Tombakmantel 3 and projectile core 2 are firmly connected.
- FIG. 9c shows the formed blank 4 after the first pressing in which the preliminary damage has been introduced. Subsequently, by pressing, preferably in only one pressing operation, both the ogive with the longitudinal grooves 5, or folds (notches) and the rear inner cone 6 are pressed.
- FIG. 9d shows the finished projectile in section and FIG. 9e shows a plan view from above of the ogive. bullet tail
- the selected shape of the projectile tail with the rear inner cone 6 serves to optimize the core compression and improves the precision of the projectile.
- Sheath wall thickness (0.2-0.5 mm depending on the caliber up to 3 mm)
- Sheath material copper or copper alloy
- Bonding process (heating temperature, heating time, cooling time, flux)
