The invention discloses a leg wire manufacturing process before the manufacture of an igniter wire welding joint of an electric detonator igniting device. The leg wire manufacturing process comprises the following steps: leg wire stranding, single-shot independent targeting and sealing plug injection molding (or / and injection molding of an igniter distance setting device). The leg wire manufacturing process adopts a multi-pair simultaneous pairing process. each pair of leg wires is always in mirror image opposition state in the process; and each pair of workpieces is segmented from the line of a middle mirror image, and the leg wire cover of a leg wire welding end is peeled off. The invention also discloses a foil-filled igniter wire welding joint which comprises an igniter wire arranged at the leg wire welding end which is in a smashing state, a foil sheet is covered on the igniter wire; and the igniter wire is welded between the leg wire and the foil sheet. The igniter wire welding joint can avoid various adverse effects of a fossa region on welding parameter stability during welding the igniter wire in a leg wire bending process. Except that a partial smashing treatment is adopted in the leg wire manufacture of an igniter wire welding region, the manufacturing process of the electric detonator igniting device which adopts the foil-filled igniter wire welding joint does not need to carry out other processes on the igniter wire welding region in the leg wire.
Description
technical field [0001] The present invention relates to a product manufacturing process of an industrial electric detonator ignition device and the structural type of bridge wire welded joints, more specifically, the present invention relates to the preparation of the legs of an industrial electric detonator ignition device before the propellant tip is dipped (including rolls) Material pay-off, twisted strands and single-shot independent handles), the manufacturing process of sealing plug injection molding to bridge wire welding, and the structural design type of bridge wire welding joints in the resistance welding process. Background technique [0002] At present, the known ignition devices for industrial electric detonators welded by the resistance welding process include three structural types: rigid charge ignition device, evolutionary rigid charge ignition device and elastic charge ignition device. Among them, the rigid charge ignition device mainly manufactures the proc...
