合理的模具设计。在级进模中,下料顺序的安排有可能影响到冲压件成形的精度。针对冲压件细小部位的下料，一般先安排较大面积之冲切下料，再安排较小面积的冲切下料，以减轻冲裁力对冲压件成形的影响。Reasonablemolddesign.Inprogressivedie,theorderofblankingsequencemayaffecttheaccuracyofstampingforming.Inordertoreducetheimpactofpunchingparts,thepunchingandcuttingblankingof***allareaisarrangedinthelightoftheblankingofthe***allpartsofthestampingparts.槽钢的锯削：槽钢的锯削与扁钢一样，但是要分二次从宽边面往下锯，不能在一个面上往下锯，应尽量做到在长的锯缝口上起锯，因此工件必须多次改变夹持的位置。Channelsteelsawing:thechannelsawingofthechannelsteelisthesameasthatoftheflatsteel,butitmustbesaweddowntwotimesfromthewideside,andcannotbesaweddownononesurface,andshouldbesawedonthelongsawmouthasfarassotheoftheclampingmustbechangedmanytimes.深缝：锯削深缝时即当锯缝的深度超过锯弓高度时，高度时，锯弓就会与工具相碰，无法继续锯削；此时应将锯条拆出，将锯条转90。Deepseam:whensawingdeepseams,whenthedepthofthesawbladeexceedstheheightofthesawbow,whentheheightishigh,thesawbowistouchedbythetoolandcannotcontinuetobesawed;thesawstripshouldberemovedandthesawbladeisturned90.)
