GROUP PRESS TOOL FOR MECHANICAL PRESSING OF FLAMMABLE FAST-BURNING COMPOSITIONS

Abstract

This utility model relates to the production of pyrotechnic products, specifically to devices for mechanically pressing fast-burning pyrotechnic igniters into delay housings, and can be used in the serial and automated production of pyrotechnic delay housings. The group pressing tool comprises a die into which pyrotechnic delay housings are installed. Guides are located on the die, based on die guides. Punches are then inserted into the guides during pressing, with stops located under the punch heads if necessary. The design enables simultaneous pressing of the pyrotechnic composition into multiple housings in a single work cycle. The technical result achieved through the use of this utility model is increased labor productivity due to the simultaneous pressing of multiple products.

Description

[0001] This utility model relates to the production of pyrotechnic products and is designed for the mechanical pressing of fast-burning pyrotechnic igniters into pyrotechnic delay devices. It can be used in the serial and automated production of pyrotechnic delay devices.

[0002] A device is known from the prior art that contains a matrix in which the body of the product is placed, and punches that perform reciprocating movements to compact the composition, which is described in the patent: “A method for assembling primer caps and a press tool device for implementing it” (Patent RU No. 2174668 C1, IPC F42B 3 / 195, F42C 19 / 10 - 10.10.2001, Bulletin No. 28)

[0003] The closest technical solution used as a prototype is the "Installation for pressing explosive charges in a group method" (Patent SU No. 1841255 A1, IPC C05B 21 / 00 - 27.12.2016, Bulletin No. 36), which contains a matrix, punches, and a limiter. A disadvantage of this device is its intended use only for pressing explosives.

[0004] The technical problem that this utility model is aimed at solving is the creation of a group pressing tool for pressing pyrotechnic compositions into retarder housings, which makes it possible to reduce the labor intensity of product production.

[0005] The technical result consists in providing the possibility of group simultaneous pressing of igniter fast-burning compositions directly into the housings of retarders.

[0006] The group pressing tool (Fig. 1) proposed as a utility model ensures the simultaneous pressing of a pyrotechnic composition into several housings in one working cycle with the same value of specific pressure for each pressing, which makes it possible to significantly reduce the labor intensity of manufacturing products, freeing some personnel from performing dangerous operations.

[0007] The group press tool contains a matrix (1), guides (2), limiters (3), punches (4) and matrix guides (5).

[0008] The pressing process begins with cleaning the pressing tool of dust and pyrotechnic residues, and treating the working surfaces with a material that prevents the composition from sticking. The pyrotechnic retarder housings are installed in the die (1). The guides (2) are then positioned on the die (1), resting on the die guides (5). The pyrotechnic composition is poured through the opening in the guides (2) using a non-ferrous metal funnel. Punches (4) are then installed in the guides (2), with stops (3) placed under the heads of the punches (4) if necessary, and the composition is pressed in.

[0009] Full technical and design documentation has been developed for the group pressing tool. A batch of pyrotechnic retarder housings was manufactured and tested using the group pressing tool, with positive results.

Claims

A group pressing tool for mechanically pressing igniter fast-burning compositions into pyrotechnic retarder housings, comprising a matrix, guides, limiters and punches, characterized in that the pyrotechnic retarder housings are installed in a matrix, on the guides of which guides with an opening are placed, while the punches are installed in the guides, and the limiters are installed under the heads of the punches.
