冷鍛頭模具鍛造參數最佳化設計
Studies on Tool Wear Analysis and Parameters Design Optimization for Cold Forging
摘要
本研究藉由電腦輔助設計與電腦輔助工程的方法，並透過有限元素分析法，套裝軟體DEFORM-3D來進行冷鍛頭之冷鍛製程應力模擬分析，進而縮短實際試模時間與快速掌握成形之條件與製程參數。另一方面，本研究將標準3D機械設計軟體Solid Works建構螺絲、胚料與模具並轉檔輸出*.STL至DEFORM-3D中，來進行製程模擬。 同時配合田口實驗計畫法針對主要參數進行模擬分析規劃，由田口式回應分析可反應出各個因子不同水準間的差異，進而得知各個因子對於模具承受的應力有何影響，並獲得一組最佳化設計的參數組合。用系統化的方式分析模具在製程中所承受的應力，結果發現，應力、應變與金屬流動明顯受到模具外形參數的影響，由冷鍛頭模具的模擬結果顯示，在高主應力區的位置與模具實際破壞位置相符。經過田口實驗方法分析可降低模具應力負荷，此結果可提供模具設計業者作爲參考，並有助於經驗累積與技術傳承。

In the industry, the forging die design mainly depends on the trial-and-error experiences. These technical approaches can not improve die design effectively and efficiently. This study will apply the method of CAD (Computer Aided Design) and CAE (Computer Aided Engineering) in resolving the above mentioned issues. And it is expected to shorten the time of on-site testing through the DEFORM-3D software which uses FEM (Finite Element Method) for heading and thread rolling simulation. So as to reduce the actual mold testing time and control the parameters of forming processes. On the other hand, this research combines the standard 3D design software (Solid Works). This system not only could construct CAD model of the screw, blank, and mold fatly, but also could transfer the files in *.STL format to DEFORM-3D for processes simulation. Simultaneously coordinates the field mouth test plan law to carry on the Simulation analysis plan in view of the main parameter, responds the analysis by TianKoushi to be possible to respond each factor during different standard the difference, then knew each factor has what influence regarding the mold withstanding stress, and obtains a group of optimization design the parameter combination. May reduce them old stress and load after the field pretext proven prescription law analysis, this resume provide the mold to design the entrepreneur to Reference, and is helpful to the experience accumulation and the technical inheritance.
