一般深引伸製程為防止板料起皺,常使用壓皺板,但此舉會造成模具較為複雜、引伸負荷增大、模具較易磨損及板料引伸易於破裂等缺點,因此無壓皺板之深引伸製程自有其優勢。本文利用有限元素法研究無壓皺板之非軸對稱深引伸製程模具設計,探討傳統倒圓角模具、圓錐形模具、成形品外形掃出錐型模具、成形品外形掃出Tractrix型模具、成形品外形掃出具反曲點曲線模具等五種模具對非軸對稱深引伸成形負荷、最大板料起皺壓應力、成形品破裂參數及成形品高度分佈等之影響。
To avoid wrinkling in traditional deep drawing process, a blankholder is used generally. But that will be more complicated in the dies construction, more high in the drawing load, more wear in the drawing die and easily fracture in the workpiece. Therefore, there are some advantages to a drawing process without the blankholder. In this paper, the finite element method is adopted to study the die shape design of a non-axisymmetric deep drawing process without the blankholder. A series of simulations on the non-symmetric deep drawing with a traditional die, a circular cone die, a die by sweeping the product profile along an oblique line, a die by sweeping the product profile along a tractrix curve and a die by sweeping the product profile along a reflection curve, respectively, using the program DEFORM 3D was carried out. The influences of the die parameters such as die angle, die length on the drawing load, the maximum tangential compressive stress of the workpiece, the maximum damage value of the drawn cup and the height distribution of the drawn cup are investigated.
