Description

The The invention relates to a training ammunition according to the preamble of claim 1.

Such a training ammunition is from the DE 88 14 176 U1 known. In this known training ammunition forming the tracer pyrotechnic ammunition capsule in the blind hole of the core part is fixed by means of a ring element. The installation of this ring element requires an effort.

From the GB 276,690 A is a projectile for a training ammunition known in the back in a blind hole by a thread an inner lid can be screwed.

Of the Invention is based on the object, a training ammunition of the above mentioned type, in which the production cost and consequently the production costs are reduced.

These Task becomes with a training ammunition of the aforementioned type according to the invention by the features of the characterizing part of claim 1. Preferred embodiments or further developments of the practice ammunition according to the invention are in the subclaims characterized.

By the training of the invention the practice ammo, in which the central core part starting from its end face with an extended into the core part or with an internal thread trained blind hole is provided, in which the tracer is pressed, This results in a comparatively simple production of the training ammunition with reduced production costs, wherein the tracer in the Blind hole of the core part reliable is fixed.

The formed in the core part blind hole can starting from the end face continuous, i. be conically extended trained. Another possibility consists in starting the blind hole from the end face into the interior of the core part stepped into expanded form. A very reasonably priced realizable embodiment arises when the blind hole formed with an internal thread is. Such an internal thread is very simple and time-saving feasible.

When has appropriate it turned out, if the pressed into the blind hole tracer kit back is sealed to protect against moisture. This seal can be effected by a sealing varnish. Such a training ammunition has excellent storage properties.

Prefers it is when in the practice ammunition according to the invention, the core part from a rod-shaped Profile semi-finished consists of the front side with a top section and the back is formed with the blind hole. The top section can hereby for example, produced by twisting off the bar-shaped profile semi-finished product become. The blind hole can with the help of a drilling tool or through Turning and threading be formed. In any case, results a cheap to be realized core part of the training ammunition according to the invention. It can be for the core part the practice ammunition according to the invention a rod-shaped Semi-finished profile with longitudinal ribs or with longitudinal channels come to the application, which are provided in the circumferential direction equidistant.

at the training ammunition according to the invention can the core part to the back Covering the end surface Plastic jacket formed integrally with a guide ring bead be. In this way, a running or tube-friendly practice ammunition, wherein a post-processing of the plastic shell on its outer surface in an advantageous Way is not necessary. Such a training ammunition is therefore easy and inexpensive produced. Through the plastic jacket or through the integral Führungsringwulst the plastic sheath is set caliber in this training ammunition. This may, for example, 20 mm, 35 mm or the like. be.

A Another embodiment of the training ammunition according to the invention is characterized in that the core part formed with a circumferential groove in which a the caliber Defining the practice ammunition guide ring pressed is. The core part may for example be made of steel, aluminum or the like. consist. The plastic jacket is preferably made of a temperature-resistant and crack-resistant Plastic material.

Further Details, features and advantages will be apparent from the following Description of embodiments of the training ammunition according to the invention shown in the drawing, it being understood that the Invention not on the training shown in the drawings is limited. Show it:

1 in a longitudinal sectional view a first training of the training ammunition,

2 a cross section through the training ammunition according to 1 along the section line II-II,

three a side view of the core part of the training ammunition according to the 1 and 2 .

4 a front view of the core part according to three in the direction of arrow IV,

5 in one of the 1 similar longitudinal section a second training of the training ammunition,

6 a cross section through the training ammunition according to 5 along the section line VI-VI,

7 the core part of the training ammunition according to 5 and 6 in one of the three similar side view,

8th a front view of the core part according to 7 in the direction of arrow VIII,

9 a third embodiment of the training ammunition in a 1 and 5 similar longitudinal section,

10 a cross section through the training ammunition according to 9 along the section line XX,

11 the core part of the training ammunition according to 9 and 10 in a the three and 7 similar side view,

12 a section through the core part according to 11 along the section line XII-XII,

13 on a larger scale, the rear end portion of a training of the training ammunition, and

14 one of the 13 similar representation of another training of the training ammunition.

The 1 and 2 show a first training of the training ammunition 10 that is a core part 12 as it is in the three and 4 is shown, and a respective launch tube gentle plastic sheath 14 which has the core part 12 up to its back end surface 16 covered.

The core part 12 consists of a metal, ie a bar-shaped semi-finished profile, the front side with a tip section 18 and back with one from the end face 16 outgoing blind hole 20 is trained.

In 14 is a blind hole on a larger scale 20 clarifies that from the back end surface 16 of the core part 12 starting in the interior of the core part 12 stepped in expanded is formed. In contrast, illustrates the 13 a blind hole 20 with an internal thread 22 is trained.

In the blind hole 20 of the core part 12 the practice ammunition 10 is a tracer 24 pressed in by the inside of the core part 12 in extended training of the blind hole 20 or by the formation of the blind hole 20 with an internal thread 22 in the blind hole 20 is reliably fixed.

To the in the blind hole 20 pressed-in tracer 24 To protect against external influences, especially against moisture, is in the blind hole 20 pressed-in light track set 24 on the back with the help of a sealing varnish 26 sealed.

In the 1 to 4 is a training of the practice ammunition 10 represented, in which the core part formed by a bar-shaped semi-finished profile 12 longitudinal ribs 28 owns, in the circumferential direction of the core part 12 are provided evenly distributed, as from the 2 and 4 is apparent. In contrast, the clarify 5 to 8th an education of the practice ammunition 10 or a core part 12 the practice ammunition 10 that instead of longitudinal ribs 28 longitudinal grooves 29 having, in the circumferential direction of the core part 12 Equidistant are provided. Incidentally, the training ammunition 10 according to the 5 to 8th the practice ammunition 10 according to the 1 to 4 similar, so that it is unnecessary to describe all the details in detail in connection with all these figures.

In the training of the training ammunition 10 according to the 1 to 4 and according to the 5 to 8th is the one with the core part 12 firmly connected plastic jacket 14 in one piece with the caliber of the training ammunition 10 defining guide ring bead 30 educated. In contrast, the clarify 9 and 10 an education of the practice ammunition 10 in which the core part 12 - as well as from the 11 and 12 can be seen - with a circumferential groove 32 is formed, in the one the caliber of the training ammunition 10 defining guide ring 34 is pressed. Same details are also in the 9 to 12 with the same reference numerals as in the 1 to 8th and 13 and 14 so that it is not necessary to describe in detail all these details.
