影响金属体积成形的因素很多,一般可归结为三大类:冷挤压原材料、成形工艺以及设备和模具。体积成形的可能性是受材料变形性能和模具承载能力限制的。这两个因素将影响和决定成形工艺和设备。 一、挤压原材料 挤压材料的选择由成品所规定的强度性能决定。材料变形强度不同对模具的应力和 There are a number of factors that affect the forming of the metal volume and can generally be grouped into three broad categories: cold extrusion of raw materials, forming processes, equipment and molds. The possibility of volume forming is limited by the material’s deformability and tooling capacity. These two factors will influence and decide on the forming process and equipment. First, the extrusion of raw materials The choice of extruded materials by the finished product of the strength of the performance of the decision. Different material deformation strength of the mold and stress
