Metal bridge transducer element and manufacturing method thereof

Abstract

The invention relates to a metal bridge electric explosion device, and provides a metal bridge energy conversion component and a manufacturing method of the metal bridge energy conversion component. The metal bridge energy conversion component comprises a substrate, a metal bridge layer, a fly die layer and an accelerating chamber layer. The metal bridge layer is formed on the surface of the substrate and made of metal materials in an additive mode through an additive manufacturing technology. The fly die layer is formed on the partial region of the metal bridge layer and the partial region of the substrate and made of non-metal materials in an additive mode through the additive manufacturing technology. The accelerating chamber layer is formed on the fly die layer and made of non-metal materials in an additive mode through the additive manufacturing technology, and a small hole is formed in the center area of the accelerating chamber layer. The region, without being covered with non-metal materials, of the metal bridge layer serves as an electrode of the metal bridge energy conversion component. According to the technical scheme, the structures of various layers of the metal bridge energy conversion component are formed through the additive technology, layered structures of core components of the metal bridge electric explosion device are formed in a sequential forming mode, and therefore man-made interference in the manufacturing process is eliminated, and accurate alignment of various components and close attachment of various layers are guaranteed.

Problems solved by technology

[0003] The traditional manufacturing method of metal bridge electric explosive devices adopts the method of mechanical processing and manual precision assembly. On the one hand, the process of this method is relatively complicated, and the cost of raw materials and labor costs are high, which ultimately leads to the production efficiency of metal bridge electric explosive devices. Low cost and high cost; on the other hand, in the assembly process, it is necessary to ensure that the center bridge area of ​​the metal bridge is accurately aligned with the inner hole of the acceleration chamber, and it is also necessary to ensure that the substrate, metal bridge, flyer, acceleration chamber and charge In close contact in the axial direction

The process is disturbed and decisive by human factors, which will have a certain impact on ensuring the reliability of the metal bridge electric explosion device.
