1.绪言在两块钢板间夹一层树脂的复合钢板中,具有代表性的是为汽车、建材、家具等轻型化需要而开发的品种。其中有在两块较薄钢板中夹科0.2～1.0mm树脂夹层的“轻型化叠层钢板”和汽车、电器产品防震为目的的在两块较厚钢板中夹入30～100μm树脂薄层的“防震钢板”。在用于实际生产制件时,进行了弯曲、拉深等冲压成形性实验研究,並用弹塑性有限元法模拟同种材料弯曲加工过程的理论解析。在实际制件应用中,观察了树脂复合钢板的切
1. INTRODUCTION Among the composite steel plates in which a resin layer is sandwiched between two steel plates, there are typically varieties developed for the light-weight needs of automobiles, building materials, furniture and the like. Among them are “light-weight laminated steel plate” with a sandwich of 0.2 to 1.0 mm resin interlayer in two thinner steel plates and a sandwich of 30 to 100 μm resin layer sandwiched between two thicker steel plates for the purpose of preventing vibration of automobiles and electric appliances “Shockproof steel plate.” In the actual production of parts, bending, drawing and other stamping formability experimental study, and the use of elastoplastic finite element method to simulate the same material bending process theoretical analysis. In the actual application of the workpiece, observed the resin composite steel cutting
