АНАЛІЗ ХОЛОДНОГО ЗВОРОТНОГО ВИДАВЛЮВАННЯ КВАДРАТНИХ І ПРЯМОКУТНИХ КОРОБОК ІЗ СТАЛІ І АЛЮМІНІЮ

Abstract

The theoretical analysis of cold backward extrusion processes of square and rectangular boxes from a low-carbon steel and plastic aluminum was carried out by a finite element method..Dependences of deforming force on displacement of the warping instrument, distribution of intensity to the puncheon, a matrix, an ejector are defined. The final geometry of the details, the mode of deformation, strengthening and ratio of metal plasticity resource after deformation were determined. By results of calculation the manufacturing method of box is developed.
