固定板沖壓成形工藝及模具設計
摘要：通過對該零件模具的設計，進一步加強了設計者沖裁模設計的基礎知識，為設計更復雜的沖裁模具做好了鋪墊和吸取了更深刻的經驗。本設計運用沖壓工藝及模具設計的基礎知識，首先分析了工件的工藝要求，為選取排樣的類型做好了準備；然后估算了板料的選取，便于導尺的寬度及確定排樣的方法；最后分析了工件的特征，確定模具的設計參數、設計要點及卸料裝置。從控制制件的尺寸精度出發(fā)，對工作零件的主要的尺寸進行了理論計算，并用CAD軟件進行各重要零件的設計。該模具為級進模,在一次沖裁時，三個孔同時沖出，沖裁力非常大，為了降低沖裁力，采用階梯沖裁。

ABSTRACT：Through parts mold design, further strengthening the designers Die basis for the design of knowledge, for the design of more complex stamping die has laid a good groundwork and learned a more profound experience. This design and use of die stamping process designed on the basis of knowledge, the first analysis of the technological requirements of the workpiece, To select the type of layout well prepared; then estimate the sheet metal selection, facilitate I. foot width and determine the layout; Finally, the workpiece characteristics, and the mold design parameters, Design and unloading devices. The size accuracy that is from the control system piece set out, to work spare parts of main of the size carried on theories calculation and counteract CAD software to carry on each importance spare parts of design.That die are compound blank and pierce dies.so while hurtling to cut once, the bore is special many, hurtle to cut dint also very big, for lowering to blank pressure, adopt stairs to hurtle to cut.
Key words : Blanking die ; mold designing; mold structure
