Description

Technical Field

[0001] The present invention relates to the technical field of gas generators, and in particular to a molded part and a molding process thereof for improving bridge wire resistance through an electroplating process. Background Art

[0002] In the production of gas generators, the industry usually designs the resistance of the ignition device by welding a metal wire with a certain resistance value (about 0.04mm diameter and about 3cm length) to the annular glass surface of the metal electrode plug through a resistance welding process to form a certain resistance. However, such a resistance wire has the following disadvantages: 1. The size of the resistance is determined by the length of the welding bridge wire. Since the bridge wire itself is very small, the resistance welding accuracy changes with the position of the welding point, resulting in a large fluctuation in the effective length of the bridge wire after welding, which leads to a large difference in the resistance of the ignition tool (R=resistivity*S / L, L effective length changes); 2. The resistance formed by the welding bridge wire. After ESD electrostatic discharge, due to the micro-welding between the bridge wire and the metal electrode plug, the length of the bridge wire carried on the glass electrode is shorter, and the bridge wire resistance is greatly attenuated (attenuation rate>20%), and the bridge wire resistance is even lower than 1.7 ohms.

[0003] Directly press-fitted on the bridge wire, the bridge wire is flattened and contacts the metal surface of the electrode plug. After the ESD is energized, the bridge wire becomes soft and the contact degree with the metal surface of the electrode plug is enhanced. At the same time, after the bridge wire is energized, the bridge wire and the electrode plug form a resistance welding loop. Micro welding causes the bridge wire and the metal surface of the electrode plug to be combined into one, and the effective length of the bridge wire is reduced, resulting in resistance attenuation; 3. The bridge wire has a thin diameter and a short length, resulting in a very small effective area of ​​contact with the detonator. If the performance of the explosive in contact with the bridge wire is unstable, the ignition performance of the ignition device will be unstable.

[0004] In summary, the existing ignition tools have the disadvantages of easy weakening of the resistor, poor contact effectiveness with the gunpowder, and low ignition stability. Summary of the invention

[0005] The present invention aims to overcome the shortcomings of existing ignition devices in the prior art, such as easy weakening of resistors, poor contact effectiveness with gunpowder, and low ignition stability.

After cleaning, stop driving mechanism 22 and driving mechanism 3 28, first open water baffle 1 41 to lower the water level and discharge it into water receiving box 1 53, and the water level will no longer drop after dropping to the height of water outlet 1 39, start driving mechanism 4 49 so that the cleaning brush 29 is rotated and lifted by the force of lifting rod 53, start driving mechanism 17, so that the lifting rod 15 drives the placement screen 13 to rise close to the nozzle 35, and then open water baffle 2 46 to lower the water level and discharge it into water receiving box 2 54, keep water baffle 1 41 and water baffle 2 46 open, and send water to the water pipe 34, so that each nozzle 35 sprays the target for secondary cleaning, and cleans the water tank 7 at the same time.

[0041] After the spraying is finished, the target is removed and sent to the electrostatic device. The target 4 is destaticized and dusted by the destaticizing device. The primer and the target 4 are heated, and the primer is sprayed on the target 4 by the atomizing spraying device. The primer is dried by the ultraviolet irradiation drying device. The target 4 is metal-plated by the vacuum coating device to form the resistor 3.
