3.
Multi-point stretch forming is a new sheet metal forming technology.
多点拉形(Multi-point stretch forming)是成形大尺寸小曲率板材的柔性加工技术,用离散的多点模具代替传统的整体模具,一套模具可以加工多种形状的蒙皮件,实现了板材快速、低成本、数字化成形。
补充资料:潘多拉
潘多拉 Pandora 希腊神话传说中的世间第一个女人。普罗米修斯盗天火给人类后,宙斯为了惩罚人类,命匠神赫菲斯托斯塑造一个女人送往人间。赫菲斯托斯遵从父命,用泥土和水,按女神模样塑造了一个女人,赋予她人的声音和力量,阿佛洛狄忒赐给她美貌和魅力,赫尔墨斯赐给她机智和狡诈,雅典娜赐给她衣饰,其他神祗也各有所赠,因而给她取名潘多拉,意为被赐予各种礼物的人。赫尔墨斯把潘多拉带到普罗米修斯的兄弟埃皮米修斯(意为后觉者)那里,埃皮米修斯不顾其兄一再要他拒绝接受神的礼物的警告,把潘多拉接受下来。宙斯让潘多拉随身带来一个盒子,潘多拉抑制不住好奇心,悄悄打开盒盖,结果禁锢于盒中的各种瘟疫、灾祸纷纷逃了出来,扩散到人间。潘多拉后悔莫及,赶紧盖上盒盖,只有一点渺茫的希望留在盒里。据说这就是世人虽饱经忧患、但仍怀抱希望的由来。 |
