| 内容記述 | In this paper, plane strain and axi-symmetric plastic flows in the forging dies which consist of horizontal and vertical passages connected with corner fillets are referred to. In the experiment, a plasticine model material has been shaped into the component with ribs or a boss. The upper-bound technique is applied to explain the patterns of material flow which were observed through experiment. In the region joining the rim or boss with the web and the flash, five typical modes of deformation appear in a certain sequence which is mainly controlled by the geometry of the die passages, width-height ratio of the flash and height-width ratio of the joining region, and by the frictional shear stress acting on the flash land. According to the deformation mode, the filling-in velocities and the forming loads appear to have much differences. In order to improve the die filling with less energy consumption, it becomes necessary to adjust the forging parameters so that in a process the optimum sequence of deformation modes can be attained. By noticing the transitional conditions of deformation mode which are clarified by experiment and predicted also by theory, an approach to the optimization of forging parameters which were done empirically so far have been systematized. | |||||
