Explosive pressing device in detonator production

Abstract

The invention relates to an explosive pressing device in detonator production, and belongs to the field of civil explosive detonator production. The explosive pressing device comprises: a bearing table and a fixing table, wherein the fixing table is located vertically above the bearing table, and a plurality of vertically-arranged supporting rods are arranged between the fixing table and the bearing table; a pressure column vertically arranged and fixedly connected to the fixing table; a pressing plate horizontally arranged between the fixing table and the bearing table, wherein the stretchingend of the pressure column extends downwards, penetrate through the fixing table, and is fixedly connected to the upper surface of the pressing plate, a plurality of vertically-arranged explosive pressing rods are arranged vertically below the pressing plate, and a plurality of height limiting columns for limiting the downward moving height of the pressing plate are further arranged vertically below the pressing plate; a mold inlet and outlet channel, wherein one end extends outwards, and the other end faces the pressing plate; and a mechanical arm for driving a mold to move between the moldinlet and outlet channel and the pressing plate. The device of the invention can accurately control the height of the explosive in the extrusion detonator, so that the quality of the produced detonator is stable.

Description

technical field [0001] The invention belongs to the field of production of civil explosive detonators, and in particular relates to a device for producing medium-pressure explosives from detonators. Background technique [0002] The detonator is the main detonating material in a blasting project. Its function is to generate detonating energy to detonate various explosives, detonating cords and detonating tubes. During the production process of the detonator, explosives need to be loaded into the detonator, and then loaded into a reinforcing cap or an extension body to make a basic detonator. After the explosives are loaded into the detonator, it is necessary to squeeze the explosives loaded in the detonator, so that the explosives are compacted in the detonator, so that the explosives in the detonator reach the rated quantity, so that the detonator can reach the corresponding power after detonation. [0003] At present, there are some charge-pressing devices in the producti...

AI Technical Summary

Problems solved by technology

[0003] At present, there are some charge-pressing devices in the production of detonators, but the effect of the charge-pressing is not ideal. Since the production of detonators cannot be completed by charging and pressing the charge once, it is often necessary to carry out multiple charge-pressing, but through the existing charge-pressing device When pressing the powder multiple times, because the height of the powder pressing column cannot be controlled, it often occurs that the powder is not compacted or the powder is over-pressed, resulting in a low yield of detonators.
