摘要：
|
|
介绍了板料数控渐进成形原理以及翼子板零件渐进成形过程,分析了工艺参数对成形的影响,提出了提高成形质量的方法。影响翼子板成形的主要参数是成形工具球头半径r和进给量h。成形过程中,工具头的球半径r应尽可能大,但考虑干涉问题,一般取较大值5 mm,有利于成形。工具头进给量h应尽可能小,这样有利于提高表面质量,使变形更加均匀,但过小时成形效率太低,因此进给量一般取较小值0.25 mm最好。

The principle of NC incremental sheet metal forming and the forming process of the fender were introduced.The effect of process parameters on forming was analysed.The improvement method of the forming quality was suggested.The forming tool radius r and feed pitch h were the main process parameters in NC incremental forming of fender.Considering the interference,the larger forming tool radius r(r=5 mm) is advantageous to forming.The feed pitch h should be as small as possible in order to improve the surface quality and to make the deformation more uniform.But the forming efficiency shall be very low if feed pitch is too small.In general,the feed pitch of 0.25 mm is good.
