Definitions

  • the invention relates to a casting funnel for filling projectiles with explosives.
  • a pouring funnel is known from European patent application 50 380. This sits in the cylindrical mouth hole of a shell.
  • the object of the invention is to propose a pouring funnel with which the entire thread and the free space serving as thread runout remain unwetted by the explosive when it is being poured. This object is achieved by the invention according to the characterizing features of claim 1.
  • the sealing stocking shuts off both the space between the sealing stocking and the projectile casing and the space between the sealing stocking and the casting funnel in a liquid- and gas-tight manner by inserting the pouring funnel.
  • the sealing effect in the space between the sealing stocking and the projectile casing is improved by the explosive pressing the sealing lip against the projectile casing. This also results in a so-called "edge seal" in which the lower edge of the free space lies in the radius between the sealing bead and the sealing lip.
  • a projectile casing 1 has a thread 2, a free space 3, a cylindrical section 4 of a cavity 6 filled with explosives.
  • a sealing stocking 10 consists of a rubber part 11 and a vulcanized stop ring 12.
  • the rubber part has a neck section 13 corresponding to the length of the thread 2, a foot section 14 which almost fills the free space 3 and then a sealing lip 15 with an inner cone 16.
  • Two rounded sealing beads 20, 21 and on the inside a rounded locking bead 23 and a cylindrical and a conical section 25, 26 are provided on the foot section 14.
  • a casting funnel 30 made of aluminum has a conical bore 31, a stop surface 32, a section 33 corresponding to the locking bead 23, a shoulder 34, ventilation bores 35.
  • the sealing stocking 10 is first inserted into the shell 1 until it stops.
  • the foot section 14 snaps into the recess 3, the sealing lip 15 having already been pressed onto the cylindrical section 4.
  • the pouring funnel 30 is then inserted into the sealing stocking 10 until the locking bead 23 snaps into the corresponding recess in the foot section 33.
  • both the pouring funnel 30 and the sealing stocking 10 are fixed in position in the projectile casing 1 and cannot be moved in the direction of fall 40 by the buoyancy forces from the sealing stocking 10 and the pouring funnel 30 in the liquid explosive 5.
  • the liquid explosive rises in the shell 1 to level 41 and, due to the inner cone 16, additionally presses the sealing lip 15 against the section 4.
  • vent holes 35 discharge the air into the inner hole 31. There the air rises through the liquid explosive in the direction of arrow 40.
