| 摘 要： | 金属板材冷冲锻成形是近年来发展起来的复合成形新技术,其特点是板材冲锻时不但完成零件形状的成形,还兼有局部结构的体积成形,如凸柱成形.针对带有凸柱的散热板基座,通过对1100-H14铝合金板材冷冲锻成形有限元模拟,探讨坯料厚度、坯料形状、摩擦因数及模具结构对凸柱成形的影响规律.结果表明:坯料越厚,越有利于凸柱成形;摩擦因数越大,越有利于凸柱成形;圆形坯料形状及带有背压的模具结构有利于凸柱成形.模拟结果与实验结果吻合.

| Abstract: | Cold press forging forming of sheet metals is a new technology for complex forming, developed in recent years. During press forging the sheet, it has the features that not only the geometries of the part can be shaped, but also local structures like embossment can be formed simultaneously. In order to shape a heat sink base with embossment, the forming process of cold press forging of 1100-H14 aluminum alloy sheet was simulated based on the finite element method, and the blank thickness, blank shape, fricti... |
