分析电液成形法时,研究了两种工艺过程图;通过冲击型砂上方的柔性薄膜来紧实型砂和在机器工作台上据击以紧实型砂。用来紧实型砂的能源——放电参数为:U=60仟伏,C=12微法拉,L=15兆米的18瓩的脉冲发生器在液体介质中的高压放电。第一种情况(图1α)在位于工作台且装有型砂的砂箱4上固定一流动水室1(耗水量 In the analysis of the electrohydraulic forming method, two kinds of process charts were studied; the sand was compacted by the flexible film above the impact sand and clamped to the compaction sand on the machine table. The energy used to compact the sand - discharge parameters: U = 60 kV, C = 12 microfarads, L = 15 Mm 18 瓩 pulse generator in the high-pressure liquid discharge medium. In the first case (Fig. 1a), a flow chamber 1 is fixed on a flask 4 equipped with a molding sand and sand table 4 (water consumption
