The analysis of distributions of effective strain and flow stress in longitudinal sections of cold backward extruded copper cans for different punch-face shapes

“…Cold backward extrusion of circular-shaped parts made from copper and aluminium and the design of the tooling have been reported in some studies [1,4,5,7,[9][10][11][12][13][14][15][16][17][18][19][20]. Those covered both experimental and computer modelling investigations.…”

“…Zasadziński [10] evaluated the usefulness of different methods for continuous extrusion of aluminium and its alloys, based on the analysis of active friction forces possible to achieve in these methods. The Linex, Extrolling, Conform processes, as well as two methods proposed by the author were analysed.…”

Evaluation of the Possibility of Performing Cold Backward Extrusion of Axisymmetrical Thinwalled Aluminum Die Stampings with Square Section / Ocena Możliwości Wyciskania Przeciwbieżnego Na Zimno Osiowosymetrycznych Wyprasek Z Cienką Ścianką O Przekroju Kwadratowym Z Aluminium

“…Cold backward extrusion of parts made form aluminum and the design of the tooling have been reported in some studies [1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Those covered both experimental and computer modelling investigations.…”

Metal Flow During Extrusion of Non-Circular Sections

“…The wide use as well as production of shapes about with complex cross-sections creates the need conduct researches to make investigations including the analysis of structure of the material as well as its transformation in different temperature -velocity -force conditions. One of basic criteria to evaluate possibilities of forming in the process of plastic work are the amount of quantify of pressures and their distribution on contact surface from tool [1][2][3][4][5][6][7][8][9][10][11][12]. Many factors influence on the magnitude of unit pressure.…”
