The invention discloses a method and device for automatically grabbing detonators. A device for grabbing the detonator is arranged on a middle blocking production line or an opening closing production line of the detonator; a group of expansion heads are arranged at the bottom of the device; the opening of the detonator is expanded and clamped by the expansion heads through the lifting of a cylinder control device and the deformation of the expansion heads to realize the purpose that the detonator is automatically taken out from a detonator filling mould. In the invention, the expansion heads controlled by machinery are adopted, and the opening of the detonator is expanded and clamped after the expansion heads are deformed, so that the detonator is automatically taken out from the detonator filling mould. A plurality of expansion heads are arranged at the same device, thus a plurality of detonators can be taken out by one device at one time, thereby greatly improving the production efficiency. The method provided by the invention is simple; and the adopted device is easy to manufacture, and has a good using effect.

To provide an electric ignition tool for firework which inhibits flame from extending far behind the ignition tool upon ignition of the electric ignition tool, and has an improved inflammation character with respect to an explosive device for inflammation and a blasting-off explosive.SOLUTION: An electric ignition tool for firework is fixed on an inflammation explosive device for ignition or fixed directly on a blasting-off explosive, so as to be used for igniting the firework, and comprises: an igniter holding cylindrical body made from a resin material or a rubber material; igniter in a powder or particle state; and a plug with a bridge circuit, which plugs the igniter holding cylindrical body to transmit ignition energy, and through which a lead wire is disposed. Therein: the igniter holding cylindrical body is fixed on the plug with the electric circuit such that the electric circuit and the igniter contact closely, the igniter holding cylindrical body has a structure being bottomed with a vicinity of a bottom plate part and / or a peripheral side wall part being caused to explode by an ignition power; the igniter is a composition including metal oxide, a single metal reductant agent, and boron.SELECTED DRAWING: Figure 2

This utility model proposes an electronic detonator assembly control system, including a housing, an injection hole, and a mounting bracket. An electric telescopic rod is mounted on the mounting bracket, and a T-shaped rod is mounted on the output end of the electric telescopic rod. A sleeve is fitted over the T-shaped rod. A sealing cover is fixedly mounted at the bottom of the mounting bracket. A partition divides the original injection hole into two parts. A measured amount of waterproof adhesive is injected using an injection head. The waterproof adhesive enters the waterproof cavity from one side, while the other side ensures air escapes. This makes the injection process more stable and efficient, while also preventing gas residue inside and reducing the defect rate. Furthermore, the partition is made of stainless steel with a smooth surface that does not adhere to the waterproof adhesive, allowing for repeated operation over a long period.

This utility model proposes an automated production system for electronic detonator ignition elements, including a base, lead wire, and lead wire reel. The lead wire reel is mounted on the base, and lead wire is wound on the lead wire reel. One end of the lead wire passes through the base and is slidably connected to it. A guide frame is fixedly mounted on the base, and a fixing frame is fixedly mounted on the top of the guide frame. A cylinder is fixedly mounted on the fixing frame, and a connecting rod is fixedly connected to the output end of the cylinder. By setting an annular coating box, continuous uneven rubber protrusions are added to the surface of the lead wire, and the diameter of the lead wire is increased. In this way, when passing through the clamping guide rollers, the lead wire between the two clamping guide rollers is fully clamped, thereby maintaining sufficient friction. This reduces the size of the equipment while ensuring sufficient friction, thus reducing the floor space cost of the factory.

The application discloses a full-automatic electronic detonator production line, which comprises a conveying belt and a conveying carrier driven by the conveying belt, and further comprises an automatic wire winding and moving device, a wire end shaping device, a stripping and wire shaping device, a wire twisting device, an injection molding device, an inner sheath stripping device, a riveting device, a laser welding device, a base pipe loading bayonet device and a detonator packaging assembly which are sequentially arranged along one side of the conveying belt; a junction box lower cover assembling device and a junction box upper cover assembling device are sequentially arranged on the other side of the conveying belt, and the junction box lower cover assembling device and the junction box upper cover assembling device are both located between the stripping and wire shaping device and the detonator packaging assembly. The full-automatic electronic detonator production line can realize full-automatic production and packaging of electronic detonators, does not need manual assistance in the whole process, is beneficial to improving production efficiency and ensuring personal safety of workers.

Explosives using thermally expandable microspheres (TEMs) in a solid matrix are disclosed that facilitate tunable changes in local density, porosity, and ultimately, shock sensitivity. Solid high explosive systems with “on demand” shock sensitivity may be created. A relatively small fraction (e.g., 1% or less) of TEMs may incorporated during the manufacturing process of the solid matrix explosive (e.g., polymer-bonded explosives (PBX), trinitrotoluene (TNT), etc.). The fraction of TEMs used to achieve the desired explosive properties will depend on the base explosive material to achieve the desired initiation sensitivity.
