A safe detonator welding method and its welding protection device

Abstract

The invention provides a safe detonator welding method, comprising the following steps: installing the detonator to be welded into a welding protection device, placing the lower part of the detonator in the limiting groove of the base, pressing the upper pin of the detonator from two pieces Expose between the blocks; adjust the orientation of the welding protection device so that the bell mouth of the pressure relief tank faces no man's land, and the operator is on the opposite side of the bell mouth; weld the detonator pins; clean the solder joints and complete the welding. The invention provides a safe detonator welding method and its welding protection device, which can protect the life safety of operators when an accident occurs by guiding the release direction of the shock wave.

Description

technical field [0001] The invention belongs to the technical field of detonator welding, and in particular relates to a safe detonator welding method and a welding protection device thereof. Background technique [0002] Because the detonator is equipped with explosives inside, it is necessary to do a good job of safety precautions during the production process, especially in the process of soldering the signal line of the detonator pin, the temperature of the soldering iron during the welding process, the static electricity of the human body, and the welding method will cause detonation if the control is not good. Potential safety hazards of explosives. At present, detonator welding adopts soldering iron power-off welding. Before welding, the operator needs to release the static electricity of the human body. During the welding process, the operator wears anti-static wrists and other methods to prevent danger from happening, but it is still impossible to completely avoid se...

[0002] Because the detonator is equipped with explosives inside, it is necessary to do a good job of safety precautions during the production process, especially in the process of soldering the signal line of the detonator pin, the temperature of the soldering iron during the welding process, the static electricity of the human body, and the welding method will cause detonation if the control is not good. Potential safety hazards of explosives. At present, detonator welding adopts soldering iron power-off welding. Before welding, the operator needs to release the static electricity of the human body. During the welding process, the operator wears anti-static wrists and other methods to prevent danger from happening, but it is still impossible to completely avoid serious consequences caused by negligent operation. , need special protection device, as the Chinese patent of publication number CN203240970U provides a kind of shock plate detonator detonation test tooling, comprises pulse power source and shock plate detonator, described pulse power source is connected with shock plate detonator, the pulse power source There is a detonation protection plate between the shock plate detonator, and the detonation protection plate is airtightly connected with an explosion-proof tank. When welding, the detonator is placed in the welding protection base, and only the electrode (welding part) is exposed outside the welding protection part to ensure that the shock plate detonator The welding process is safe, but the welding protection part is a closed space, and the high-pressure gas generated by the detonator explosion can only be released from the welding port, which cannot 100% prevent the high-pressure gas from damaging the electrode position of the detonator itself and release the impact, that is, the operation cannot be 100% guaranteed Personnel safety, there is a certain security operation risk
