使用数控渐进成形机床,打破传统热渐进成形的外部热源加热方式,利用工具头转动时与板料之间产生的“绿色”摩擦热成形AZ31B镁合金板料。通过实验综合研究几种不同润滑剂对AZ31B镁合金板料的渐进成形能力及成形表面粗糙度的影响,结果表明:与石墨粉末、MoS2粉末、石墨喷剂和粘附型石墨相比,选用锂基高温润滑脂,镁合金板料有更好的渐进成形能力,成形角≥60°,且成形表面的粗糙度Ra值约为2.47μm。 The use of CNC progressive forming machine to break the traditional hot forming of the external heat source heating method, the use of tool head rotation between the sheet and the resulting “green ” friction thermoformed AZ31B magnesium alloy sheet. The effects of several different lubricants on the as-formed capability and forming surface roughness of AZ31B magnesium alloy sheets were comprehensively studied through experiments. The results show that compared with graphite powder, MoS2 powder, graphite spray and adhesion type graphite, Base high temperature grease, magnesium alloy sheet has a better ability of progressive forming, forming angle ≥ 60 °, and the forming surface roughness Ra value of about 2.47μm.
