发明名称 HAOLPATRON MED RIKTAD SPRAENGVERKAN OCH FOERFARANDE FOER FRAMSTAELLNING AV EN METALLISK KON FOER HAOLPATRON
摘要 The invention is concerned with a hollow charge of a directed explosion effect as well as with a method for the manufacture of the metallic cone of the hollow charge. The hollow charge (1) comprises a mantle (2) of the charge portion, an explosive material (3) fitted inside the mantle, a detonator (7) fitted at one end of the charge (1), and a metal cone (5) fitted at the opposite end of the charge (1). The mantle (2) of the hollow charge (1) and the metal cone (5) are precisely centered on a common symmetry axis (6). The detonator (7) is also positioned on the said symmetry axis (6). According to the invention, as viewed from the direction of the object to be blasted, the shape of the cone (5), made of pure copper, of the hollow charge (1) is in such a way differential that the convexity (a) of the wall (9) of the cone (5), whose thickness is uniform within the area of the entire cone, from the wall of a straight cone of equal cone angle is less than the thickness of the wall (9) of the copper cone (5), preferably about one half of the said thickness of the wall (9) .
