拉深用板材塑料涂层的单双面性

ONE—SIDED AND TWO—SIDED CHARACTER OF PLASTIC FILM COATEd ON METAL SHEET FOR DEEP DRAWING

用软钢、不锈钢、铜和铝几种涂复塑料薄膜层板材分别进行了筒形件及曲面零件拉深成形的成形性能试验研究。从试验得到的相应结果并经有关分析,提出了一个新观点:筒形件拉深以及以拉深变形为主的曲面零件的拉深成形,应采用单面涂层板材;盒形件拉深以及以胀形变形为主的曲面零件的拉深成形,应采用双面涂层板材。

It is resectively made about formability test research of cup drwing, square Sheel drawing and dome—shape part drawing—forming used mild steel, stainless steel, copper, Aluminium sheet with plastic film coated. On the basis of the test result and anallysis, a new poin tor view has been put forward, in cup drawing and dome—shape part drawing—forming of drawing deformation is main, it must be one—sided coaled plasic film sheet metal; And in square sheel drawing and dome—shape drawing—forming of bulge deformation is main, use tuo—sided coated sheet.
