Abstract
1501431 Making hollow charges; spinning; welding by pressure SOC NATIONALE DES POUDRES ET EXPLOSIFS and FRANCE ARMED FORCES MINISTER OF 3 April 1975 [17 April 1974] 13769/75 Headings B3A B3J and B3R [Also in Division F3] A method of making a conical bimetallic facing for hollow charges comprises explosively bonding two metal blanks of different types to form a bimetallic plate and shaping the plate into conical form by flow forming. One of the metals for the blanks produces a dense perforating jet when the hollow charge is fired while the other forms a core which either volatilizes or disintegrates. A sheet of copper or copper alloy which forms the perforating jet is explosively bonded to a sheet of zinc, lead, silver or aluminium which forms a volatilizable core or work-hardened steel which forms a disintegrating core. The bimetallic sheet, e.g. copper/aluminium having an initial thickness ratio of 1/5, is mounted in a driver 4 of a conventional spinning machine, and a conical facing is formed by advancing a rotating mandrel 2, which acts in co-operation with rollers 1, the copper layer being on the inside of the core. For bonding, an explosive charge comprised of 92À5% ammonium nitrate, 3À5% fuel oil and 4% wood flour, all by weight, is used together with a commercial detonator.
