4 Claims. (Cl. 29-4705) Bomb manufacturers for some time now have been in,
the process of developing a new type of streamlined low drag bomb. It Will be appreciated that dueto the faster air speeds being developed by presently existing aircraft and further in view of the high altitudes now attainable by them, conventional bomb structures must be streamlined and modified so as to allow precision bombing. under these more exacting conditions.
Through the use of the present inventions manufactup. ing costs have been kept to a minimum, a new streamline bomb casing has been developed, new and improved moisture proof hanger means has been provided and production costs have been kept to a minimum.
Accordingly, it is an object of this invention to provide a novel method of producing streamlined low drag type of bombs.
A further object of this invention is to provide a new and improved relationship between a bomb casing wall and a hanger stud.
A still further object of this invention is to providea new and improved method for forming bomb hanger sockets in the wall of a bomb which may be cheaply and efficiently brought about so as to enable large scale production at a minimum cost.
Another and still further object of this invention is to' provide a novel method and structure for producing, and providing a moisture proof stud socket and bomb wall connection.
In connection with the general features of thisvinvention there is provided in a method of providing a bomb hanger stud on a curved tubular casing wall of a bomb, the steps of punching the curved wall providing a circular recess having an outer beveled edge at its mouth and then punching an opening through the curved wall inwardly of therecess leaving an inner shoulder between the outer surface of the casing wall and the locale of the: recess, inserting solder on the shoulder, placing a stud having on an outer end a peripheral lateral flange in the recess with the flange resting on the beveled edge, punching centrally the outer end of the stud while supporting an opposite inner end of the stud to displace and .fiow the.
material thereof not only into underlying marginal relation to the inner shoulder about said opening but also laterally outwardly into gripping relation with the beveled edge while forming a central socket cavity in the stud,
dishing inner and outer surfaces of the stud adjacent the inner shoulder and the beveled edge thereby further bulging and nesting the stud into snug nested engagement with Still another feature of the present invention relates. to the provision of a bomb casing structure, which structure includes a tubular casing having a curved wall, a socket hole through the wall having radially inner and outer casing wall shoulders, and a stud in the opening having laterally extending inner and outer longitudinally spaced stud portions overlapping the shoulders interlocking the stud in assembly with the shoulders, the stud being dished adjacent the laterally extending portions with the portions thereby bulged into snug nested engagement with the shoulders.
Other objects and features of this invention will more fully appear from the following detailed description taken in conjunction with the accompanying sheets of drawings which illustrates a single embodiment thereof and in which:
-FIGURE 1 is a plan view of a bomb casing showing the stud sockets in a completed state;
FIGURE 2 is'an enlarged longitudinal cross section illustrating a preliminary step in my method;
FIGURE 3 is an enlarged cross sectional'view showing in full and dotted lines the relationship of the bomb casing wall with respect to a hanger stud; 7
FIGURE 4 is an enlarged side elevation of a bomb hanger stud;
FIGURE 5 is an enlarged front elevation of the bomb hanger stud shown in FIGURE 4;
FIGURE 6 is an enlarged cross sectional view showing a later step in my method wherein the hanger stud is being interlocked with the casing wall by apparatus;
FIGURE 7 is an enlarged fragmentary cross sectional view taken on the line VII-VII of FIGURE 1 looking in the direction indicated by the arrows; and
FIGURE 8 is an enlarged fragmentary cross sectional view taken substantially on the line VIII-VIII of FIG- URE 1 looking in the direction indicated by the arrows.
As shown on the drawings:
The reference numeral 10 in FIGURE 1 indicates generally a tubular bomb casing having a curved Wall 11 including radially outer and inner surfaces 12 and 1-3 on the wall 11. Axially spaced along the length of the casing 10 are a series of bomb hanger stud sockets 14 which may be of varying dimension and each of which is adapted to receive in threading engagement therewith a bomb hanger element (not shown).
wherein the curved wall 11 is punched to provide a cir- V cular recess 15 having an outer beveled edge 16 at its mouth. To this end, the material of the casing wall is forced radially inwardly into a recess 17 provided in a female die member 18'. It will be noted that the diameter of the recess 17 is slightly smaller than the diameter of the recess 15. V
The next step comes about by punching an opening 18 through the curved wall 11 inwardly of the recess by means of a punch (not shown) corresponding in diameter to ,the diameter of the recess 17. By virtue of utilizing a punch having a diameter slightly smaller than the diameter of the recess 15, after the opening 18 has been provided, an annular shoulder 19 is caused to be formed.
Ametallic slug or stud 20 of predetermined shape is shown FIGURE 3. By virtue of preforming the head arr raise portion and peripheral flange portion 21 of the stud 29 the stud may be inserted within the opening 18 and the upper surface 22 of the stud will smoothly blend with the curvature of the outer casing surface 12.
In FIGURE 6, apparatus is shown for reforming the stud 2-0 in a manner so that the stud is in interlocked engagement with the casing wall 11. To this end, an upper die member 23 is provided which is adapted to nestingly engage against the outer surface of the bomb casing wall 11. The die member 23 has a bore 24 which contains a vertically movable punch 25. The'punch 25 has a dishing projection 26 for purposes which will hereafter be discussed in detail. A screw 27 is utilized to secure together the punch 25 with an insert punch member 28 which is lodged within a recess 29 provided in the punch 25. In the operation of the punch 25, in a punching operation, the member 29 serves to punch out a socket 30 in the stud 20.
Positioned inside of the tubular casing wall 11 is a female die member 31 having a recess 32 of predetermined configuration and which has a slightly larger diameter than the outside diameter of the reduced portion of the stud 29.
Before the stud 20 is interlocked with the casing wall, a solder ring 33 is placed upon the shoulder. The solder may be of any suitable material such as silver solder, bronze or copper solder.
After the inner die member 31 and the outer die member 23 have been engaged against the inner and outer surfaces of the casing wall 11, the punching member or ram 25 may be then urged against the stud 20. When the punching member 25 is urged against the stud 20, the socket 30 is formed centrally of the stud. In addition, the dishing projection 26 causes the material of the stud to be moved outwardly into snug engagement with the casing wall. Inner and outer spaced shoulders 34 and 35 have been provided at the junction of the inner and outer surfaces 13 and 112 with the opening 18. Thus, when the ram or punch member 25 is moved downwardly against the stud 20, the material of the stud is caused to move laterally outwardly away from the dishing projection 26 into snug nested engagement against the shoulder 35. In addition, and also occurring during the punching operation, the material of the stud is caused to move laterally outwardly to fill the larger diametered recess32 with the result that the stud 20 underlaps the casing wall 11 in engagement with the inner shoulder 34. To facilitate the provision of a snug fit between the underlapped material of the stud and the shoulder 34, the recess 32 has a bulged annular portion 36 positioned in the recess between the shoulder 34 and the bottom of the stud 20. Thus, when the punch member 25 is urged downwardly against the stud, the material of the stud is caused to flow generally radially of the axis of the stud to fill the recess with the bulged portion 36 in the recess creating .a dished area in the stud 20 thereby enabling snug engagement between the underlapped material of the stud and the shoulder 34.
The ring 33 may be of a bronze-copper brazing material having a melting point at about 1600 F. This ring may be fused with the casing wall 11 and the stud 20 by being heat treated at about 1600" F. in a salt bath. This not only advantageously treats the material 'of the work insert but fuses the brazing ring and causes the same to effectively flow into and seal the joint between the shell casing and the socket insert to provide a fluid type joint. The salt of the salt bath serves as an efficient flux during the brazing.
The insert stud or slug may be hot or cold and if hot is heated to 1600 to 1650 F. before being dropped into the opening 18.
It will be appreciated, a significant feature of the present invention resides in having the side wall of the die recess or cavity of generally convex form leading into a concave fillet so that a generally ogee contour is provided CJI 4 that flares outwardly at the mouth. This has been found to effect an efiicient flowing of the material into tight substantially gapless engagement of the shoulder of the socket slug against the inner wall of the shell or casing defining a margin about the opening. Considerable difliculty had been experienced before this shape was developed.
It will be appreciated the dished projection 26 and the bulge portion 36 cooperate together in underlapping and overlapping the stud 20 with respect to the casing wall so as to interlock the stud 20 with the casing wall in snug engagement together.
After the studs have been assembled with the casing wall, the assembly may be heat treated to thereby melt the solder and provide a water tight or moisture proof joint between the casing wall and the studs 20.
In addition, the recess 30 in the stud 20 may be threaded so that a hanger element (not shown) may be received therein to aid in the suspension of the casing member from an aircraft.
The chronological order of certain of the steps as described is not necessarily critical in my method and therefore certain of the steps may be performed before certain of the steps as described without departing from the scope of the present invention.
It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
