金屬板材冷沖鍛成形是近年來發(fā)展起來的復(fù)合成形新技術(shù)，其特點(diǎn)是板材沖鍛時(shí)不但完成零件形狀的成形，還兼有局部結(jié)構(gòu)的體積成形，如凸柱成形。針對帶有凸柱的散熱板基座，通過對1100-H14鋁合金板材冷沖鍛成形有限元模擬，探討坯料厚度、坯料形狀、摩擦因數(shù)及模具結(jié)構(gòu)對凸柱成形的影響規(guī)律。

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, friction coefficient and die structure on the embossment forming were studied. The results show that the thicker the blank is, the better the embossment can be formed, and also the greater the friction coefficient is, the better the embossment can be done. Meanwhile, the cylindrical blank and tooling structure with counter pressure can be helpful to the form of embossment as well. The simulation results are in good agreement with the experimental data.
