SehneidCharge body

10

The invention relates to a cutting charge body with ₍ a housing and an ignition chain, consisting of a

Blasting cap/ignition amplifier, a drag ignition charge and a cutting charge.

15

In such cutting charge bodies, the ignition amplifier is also arranged in the housing. Its volume reduces the space available in the housing for the cutting charge.

The object of the invention is to gain space in the housing for the cutting charge.

According to the invention, the above object is achieved in a

( ) 25 cutting charge bodies of the type mentioned above are solved in that a receiving ring is arranged on the outside of the housing near the trailing ignition charge arranged in the housing and that the ignition amplifier has a casing with side tabs with which it can be locked to the receiving ring.

The ignition amplifier is therefore structurally separated from the housing. The space it would otherwise take up is available to accommodate cutting charges. This increases the effectiveness of the cutting charge body.

The ignition amplifier is installed as a separate component

transported with the cutting charge body and, if necessary, manually secured to the receiving ring.

In a preferred embodiment of the invention, the casing has two diametrically opposed tabs on its circumference and a recess is provided for each tab on the inner circumference of the receiving ring. When the casing is rotated in either direction, the tabs grip under ring segments of the receiving ring located between the recesses. The tabs can be turned in either direction into the

If necessary, the jacket only needs to be placed on the mounting ring so that the tabs engage in the recesses. It is then secured by turning it clockwise or counterclockwise. The jacket can also be dismantled by turning it clockwise or counterclockwise. This means that there is no need to

A cutting body has a housing (d). A cutting charge (2) is housed in this. Above the cutting charge(2) is in the housing(1) a elongated drag ignition I charge (3). On top of an elongated cover 11ei I (4) two mounting rings (5) are attached at a distance from each other, into which ignition amplifiers (CÄ) are inserted (see Figure 1). The Ignition amplifiers (6) are located above the center axis of the drag ignition charge (3).

The ignition amplifier (6) has a substantially cylindrical casing (7), on the circumference of which two diametrically opposed tabs (R,9) are formed. Cams (8,9) are formed on the top side of the lashings (see Figure 2,3).

The casing (7) is closed by an insert (11) which has a receiving space (12) for an electrical blasting capsule I (13). An ignition booster charge (1A) is arranged in the casing (7).

The receiving ring (5) is attached to the cover part (A) with its outer edge (15). On its inner circumference it has two diametrically opposed recesses (16) that correspond to the tabs (8,9). Between the recesses (16) the receiving ring (5) forms ring segments (17). Offset by 90° from the recesses (16), notches (18) are provided at the bottom of the ring segments (17) that are assigned to the cams (110). The ring segments (17) are provided with a slope (19) from the notches (18) to the recesses (16) (see Figure 5).

To mount the ignition amplifier (6) on the housing (d), the casing (7) with its tabs (8,9) is placed on the mounting (5) so that the tabs (8,9) engage in the recesses (16). The casing (7) is then

either clockwise or counterclockwise. The tabs (8/9) slide under the Ring segments (17). As the angle of rotation increases, the seat becomes tighter due to the pitch (19). When turning by 90°, the cams (0) engage in the notches (18). The The ignition amplifier (6) is now locked to the housing (CI) so that it remains firmly in place even in the event of vibrations.

If the explosive capsule (13) is ignited, the cutting charge (2) is ignited via the Ü ignition booster charge (iA) and the trailing ignition charge (O).

The ignition amplifier (6) can also be removed from the housing (CI). To do this, it is rotated by 90°, whereby the tabs (8, 9) enter the recesses (16) and the ignition amplifier (6) can be lifted off the mounting ring (5).
