Definitions

  • the present invention relates to a method for producing a Cartridge consisting of a sleeve and a projectile, which can be produced by this method Cartridges, and the use of an acrylic adhesive for sealing a cartridge from a sleeve and a projectile.
  • Cartridges that have a gap between the cartridge case and the projectile are usually sealed with a sealant.
  • bitumen as a sealant is known.
  • the cartridge cases on the so-called inner sleeve mouth with a bitumen-based sealant coated and then labored, i.e. Bullet and powder are in introduced the sleeve.
  • bitumen-based sealants When using bitumen-based sealants time and time again Problems arise. These problems include therefore that the bitumen paint used very different in its processing and material properties is. This results in different degrees of dryness when used and layer thicknesses. The different layer thicknesses lead to sleeve expansion, so that the cartridge is not loadable. Another problem is posed the displacement of the bitumen lacquer layer when processing bitumen lacquer as a sealant in the cargo space. The sleeve will leak, the cargo space is reduced. Due to the processing-related proportion of solvents there may also be compatibility problems with the propellant powder come. The sealing process is automated when using Bitumen-based sealants not possible.
  • GB 2 305 994 describes the manufacture of a cartridge from a sleeve and described a projectile in which the Gap is sealed on the inside of the sleeve. So that is the sealing one fully loaded cartridge is possible, but no procedure is described that the use of a detector that provides precise dosing and thus just the addition of sufficient amounts of the sealant for sealing allows.
  • the object of the present invention was therefore to overcome these disadvantages of To eliminate the prior art in the sealing of the cartridge cases. Solved this task was characterized by the features of the main claim and the subsidiary claims. Refinements are preferably found in the subclaims.
  • the solution according to the invention provides for the use of an anaerobically curing sealant which contains no solvent and is capillary-active.
  • a sealant from the group of acrylate adhesives is preferably used.
  • a mixture of 2-hydroxypropyl methacrylate and lauryl methacrylate with the auxiliaries and / or additives customary per se for acrylate adhesives is particularly preferred.
  • Such acrylate adhesives are known, for example, under the name Permabond®.
  • the sealants based on acrylate adhesive to be used according to the invention have a low viscosity, for example a viscosity of 7 mm 2 / s at 25 ° C., and a low surface tension, for example a surface tension of about 30 mN / m.
  • the sealant according to the invention can capillate into very narrow gaps and therefore also into the gap between the cartridge case and the projectile, the so-called inner case mouth, which is formed during the processing of cartridges.
  • the sealant before laboratory use the cartridge must be applied to the inner sleeve, sees the invention Process to seal the sealant to be used according to the invention at any time on the finished cartridge.
  • the invention The method provides for the sealants to be used according to the invention in in a controlled manner and in amounts sufficient for complete sealing, on the gap on the inside of the sleeve when the bullet is inserted into the sleeve to apply, the sealant to be used according to the invention Capillate into the gap.
  • the intended sealants harden very quickly, so that curing times are eliminated. By eliminating the curing times is one immediate further processing possible. The manufacturing lead times are drastically reduced, so that the inventive method is very excellent suitable for use in various loading and assembly machines. After curing, the sealant is resistant to thermal and chemical loads largely resistant. Because of the absence of solvents there are also none Problems with the propellant powder expected; the powder compatibility is thus given when using the sealants to be used according to the invention.
  • the use of a detector provided the precise dosing and thus just the addition of sufficient amounts of the sealant for sealing allows.
  • the invention is based on the rational design of the sealing process provided to preferably add an indicator to the sealant to be used.
  • This addition of indicators enables sealing in a special way to automate the inside of the sleeve. All means are an indicator in themselves suitable that compatible with the sealants to be used according to the invention are and can be easily detected. Fluorescence indicators are particularly preferred, UV fluorescence indicators are very particularly preferred, in particular those that are visible at a wavelength of 375 nm. The ones to be used Quantities depend on the indicator used, with the Amounts added are not critical.
  • an indicator can be added.
  • the limit can be 0.1% by weight, 0.2% by weight, 0.3% by weight or any other Accept value. The only condition is that the quantities of the indicator are the Hardening of the sealant does not affect the other side however are sufficient to be detectable.
  • this additional indicator enables quick and easy identification and checking the sealant, for example to determine whether that Sealant has completely sealed the gap.
  • the addition of the indicator enables in addition, a particularly economical use of the sealant, because the dosage of the sealant can be controlled.
  • a detector is an example called a so-called luminescence button, the UV fluorescent indicators at with a wavelength of 375 nm.
  • sealants to be used according to the invention can be used with all cartridge types are used, which a gap when joining the projectile in the sleeve Have inclusion of the sealant.
