Abstract

An explosive cutting charge is formed by machining or otherwise forming a cavity of a desired configuration within a circular ring of metal cutting material such as copper or aluminum. The cavity may then be filled with an explosive material. The cutting characteristics of the cutting charge may be controlled by the selected cross-section configuration of the cavity. The ring may contain a booster explosive charge with connections to the active portion of the ring having the cutting metal material.

Claims

exact text as granted — not AI-modified
1 . An explosive cutting charge device, comprising:
 cutting material arranged in a configuration;   a cavity formed in the cutting material configuration; and   cast cured explosive material filling the cavity, wherein a weight of the explosive material is varying or non-varying along a length of the cavity, thereby forming a cutting charge with a predetermined cut profile shape in the explosive cutting charge device.   
   
   
       2 . The explosive cutting charge device of  claim 1 , wherein the cutting material comprises a metal. 
   
   
       3 . The explosive cutting charge device of  claim 1 , wherein the cutting material comprises one of aluminum and copper. 
   
   
       4 . The explosive cutting charge device of  claim 1 , wherein the cutting material configuration comprises an enclosed configuration, wherein the cavity is formed throughout the entire enclosed cutting material configuration. 
   
   
       5 . The explosive cutting charge device of  claim 1 , wherein the cutting material configuration comprises a closed ring, wherein the cavity is formed throughout the entire closed ring. 
   
   
       6 . The explosive cutting charge device of  claim 1 , further comprising a manifold connected with the cutting material configuration, thereby forming a hermetic seal of the cutting material configuration. 
   
   
       7 . The explosive cutting charge device of  claim 1 , further comprising a manifold connected with the cutting material configuration, wherein the manifold includes a cavity formed therein, wherein a booster charge is located within the manifold cavity, wherein the booster charge is in communication with the explosive material within the cavity of the cutting material configuration. 
   
   
       8 . The explosive cutting charge device of  claim 1 , wherein one or more cut profile cutting charge shapes are formed in the explosive cutting charge device. 
   
   
       9 . An explosive cutting charge device, comprising:
 cutting material arranged in an enclosed configuration;   a cavity formed throughout the entire cutting material enclosed configuration; and   cast cured explosive material filling the cavity, wherein a weight of the explosive material is varying or non-varying along a length of the cavity, thereby forming a cutting charge with a predetermined cut profile shape in the explosive cutting charge device.   
   
   
       10 . The explosive cutting charge device of  claim 9 , wherein the enclosed configuration comprises a ring. 
   
   
       11 . The explosive cutting charge device of  claim 9 , wherein the cutting material comprises a metal. 
   
   
       12 . The explosive cutting charge device of  claim 9 , wherein the cutting material comprises one of aluminum and copper. 
   
   
       13 . The explosive cutting charge device of  claim 9 , further comprising a manifold connected with the cutting material configuration, thereby forming a hermetic seal of the cutting material configuration. 
   
   
       14 . The explosive cutting charge device of  claim 9 , further comprising a manifold connected with the cutting material configuration, wherein the manifold includes a cavity formed therein, wherein a booster charge is located within the manifold cavity, wherein the booster charge is in communication with the explosive material within the cavity of the cutting material configuration. 
   
   
       15 . The explosive cutting charge device of  claim 9 , wherein one or more cut profile cutting charge shapes are formed in the explosive cutting charge device. 
   
   
       16 . An explosive cutting charge device, comprising:
 a plurality of explosive charge cutting segments that comprises a breaching device, wherein each segment comprises a housing that contains an amount of cast cured explosive material therein, wherein a weight of the explosive material is varying or non-varying, thereby forming a cutting charge with a predetermined cut profile shape in the explosive cutting charge device, and wherein each segment has a cap well.   
   
   
       17 . The explosive cutting charge device of  claim 16 , wherein the housing comprises a friable plastic, and wherein the housing further comprises a copper liner. 
   
   
       18 . The explosive cutting charge device of  claim 16 , wherein the housing comprises a friable plastic, and wherein the housing further comprises an unvulcanized copper/polymer compound liner. 
   
   
       19 . The explosive cutting charge of  claim 16 , wherein the plurality of explosive cutting charge segments are arranged in an enclosed configuration. 
   
   
       20 . The explosive cutting charge device of  claim 16 , wherein one or a plurality of cap wells are used to detonate the entire device.
