Abstract

Shaped charge devices, systems, and related methods of use. A housing sheet is configurable to form at least part of a shaped charge enclosure enclosing a shaped charge and biasing an explosion in a desired direction. The housing sheet can include one or more incisions in at least one surface thereof. The housing sheet can have at least one connection mechanism integrally formed therein, and the housing sheet can be configurable to form a plurality of sizes of shaped charge housing portions. The housing sheet can also provide for forming a plurality of dimensions of the shaped charge enclosure.

First claim

What is claimed is:

1 . A device comprising:
a housing sheet that is configurable to form at least part of a shaped charge enclosure enclosing a shaped charge and biasing an explosion in a desired direction, wherein the housing sheet comprises one or more incisions in at least one surface thereof, has at least one connection mechanism integrally formed therein, is configurable to form a plurality of sizes of shaped charge housing portions, and provides for forming a plurality of dimensions of the shaped charge enclosure.

2 . The device of claim 1 , wherein the plurality of sizes of shaped charge housing portions defines a plurality of corresponding shaped charge enclosures.

3 . The device of claim 1 , wherein the incisions are configured to increase bendability of the housing sheet at the locations of the incisions to form the at least part of the shaped charge enclosure.

4 . The device of claim 3 , wherein the housing sheet is configurable to form a cylindrical shaped housing portion, wherein the incisions are disposed in an axial direction with respect to a formed cylinder corresponding to the cylindrical shaped housing portion, and wherein the incisions comprise slits in an outer surface of the housing sheet that are configured to increase bendability of the housing sheet to form the cylindrical shape.

5 . The device of claim 4 , comprising a circumferential incision that is disposed on a surface of the housing sheet and configured to couple to a shaped charge liner.

6 . The device of claim 4 , wherein the housing sheet further comprises hooks on an end thereof, the hooks being configured to secure a lid to the cylindrical shaped housing portion.

7 . The device of claim 4 , wherein the housing sheet is configured to form a cylindrically shaped housing portion comprises a plurality of corrugation flutes.

8 . The device of claim 7 , wherein the corrugation flutes comprise locking notches disposed in an outer surface of the housing sheet.

9 . The device of claim 4 , further comprising auxiliary coupling holes disposed in the at least one surface of the housing sheet.

10 . The device of claim 1 , wherein the incisions comprise perforations configured to provide separability of the housing sheet into a plurality of particularly defined housing components.

11 . The device of claim 10 , wherein the housing sheet is configurable to form a shaped charge enclosure having a shaped charge stand, wherein the shaped charge stand is integrally formed with the housing sheet.

12 . The device of claim 11 , wherein the shaped charge stand is configurable into a plurality of sizes.

13 . The device of claim 10 , further comprising:
a set of hooks formed in the housing sheet; and a set of hook receivers disposed in the housing sheet, wherein the hooks and the hook receivers are couplable to form a shaped charge enclosure from the housing components when the housing components are in a separated configuration.

14 . The device of claim 10 , further comprising an incision configured to couple to a shaped charge liner.

15 . The device of claim 10 , wherein the shaped charge enclosure is configured as a linear enclosure.

16 . A shaped charge system, the system comprising:
a housing sheet that is configurable to form at least part of a shaped charge enclosure enclosing a shaped charge and biasing an explosion in a desired direction, wherein the housing sheet comprises one or more incisions in at least one surface thereof, has at least one connection mechanism integrally formed therein, is configurable to form a plurality of sizes of housing portions, and provides for forming a plurality of dimensions of the shaped charge enclosure; an explosive disposed inside the enclosure of the shaped charge device; and a shaped charge liner coupled to at least one shaped charge housing sheet.

17 . The system of claim 16 , wherein the shaped charge liner forms part of the shaped charge enclosure.

18 . The system of claim 16 , wherein the plurality of sizes of housing portions defines a plurality of corresponding shaped charge enclosures.

19 . The system of claim 16 , wherein the housing sheet forms a cylindrical housing enclosure.

20 . The system of claim 19 , further comprising a lid having at least one hook slot, wherein the housing sheet further comprises at least one hook on an end thereof, and wherein at least one hook of the housing sheet is coupled to at least one hook slot of the lid.

21 . The system of claim 19 , wherein the cylindrical housing enclosure further comprises an incision disposed on a surface thereof, the incision being configured to couple to the shaped charge liner, and wherein at least a portion of the shaped charge liner is lodged in the incision in the inner surface of the cylindrical housing.

22 . The system of claim 21 , wherein the housing sheet comprises corrugation flutes which extend at least partially through the length of the housing sheet.

23 . The system of claim 22 , wherein the corrugation flutes have locking notches disposed in an outer surface of the housing sheet.

24 . The system of claim 22 , further comprising at least one joinery having connection tabs, wherein the connection tabs are disposed inside the corrugation flutes.

25 . The system of claim 24 , wherein the connection tabs are engaged with the corrugation flutes by press fit.

26 . The system of claim 24 , wherein the connection tabs are engaged with the locking notches.

27 . The system of claim 22 , further comprising at least one cable tie disposed in at least one of the corrugation flutes.

28 . The system of claim 16 , wherein the housing sheet and the liner are coupled to form a linear housing.

29 . A method of assembling a shaped charge enclosure, comprising:
manipulating a shaped charge housing sheet to form an enclosure; coupling a shaped charge liner to the housing sheet; inserting an explosive into the enclosure; and sealing the enclosure.

30 . The method of claim 29 , further comprising separating the housing sheet into a plurality of housing portions, and
forming the enclosure from one of the separated portions.

31 . The method of claim 29 further comprising:
bending the shaped charge liner to form a cylindrical enclosure;
inserting at least a portion of the shaped charge liner into an incision in an inner surface of the shaped charge liner;
placing a lid on an end of the cylindrical enclosure; and
rotating the lid to secure the lid to the enclosure,
wherein the housing sheet has hooks formed on the end the housing sheet, and wherein the lid has hook slots disposed therein which are formed to engage with the hooks.

32 . The method of claim 29 , further comprising securing the housing sheet in a cylindrical shape by inserting a joinery into corrugation flutes disposed in the housing sheet, and coupling locking notches disposed in the housing sheet to connection tabs formed in the joinery.

33 . The method of claim 29 , further comprising separating the housing sheet into a plurality of components having hooks formed thereon and hook slots disposed therein, and coupling the hooks and hook slots to form an enclosure and a shaped charge stand.

34 . The method of claim 33 , further co
