Abstract

1,102,469. Perforating. KHARKOVSKY AVIATSIONNY INSTITUT. 1 April, 1966, No. 14473/66. Heading B3W. A method of cutting blanks from moving sheet material comprises passing the material 2 adjacent the mouth of a cavity 3 formed in a housing 4, there being a plug 6 in the cavity to restrict the mouth to an annular opening. An explosive force is created which causes a fluid medium to issue from the gap as an annular jet which cuts the material. An apparatus for performing the method comprises the housing and plug, a barrel 5 having a cartridge chamber 7, a breech block 9, a spring-loaded firing pin 8 and a trigger pin 13. A cartridge is placed in the chamber 7 by removing the breech block 9 and when it is fired the gases produced pass into the cavity 3 and through the annular gap in a jet which cuts the material in 0À0001 secs. In a modification a liquid is pumped into the cavity 3 at a rate which equals the rate at which it escapes through the annular gap, and a piston 15 is inserted in the barrel 5. When the cartridge is fired, the piston moves down, and forces an annular jet of liquid through the gap between the housing and plug to cut the material.
