1、哈爾濱理工大學學士學位論文沖孔落料連續(xù)模設計及三維CAD實體動畫仿真摘要連續(xù)模,又稱為多工位連續(xù)模、級進模、跳步模,它是在一副模具內(nèi),按所加工的工件分為若干等距離的工位,在每個工位上設置一個或幾個基本沖壓工序,來完成沖壓工件某部分的加工。被加工材料,事先加工成一定寬度的條料,采用某種送進方法,每次送進一個步距。經(jīng)逐個工位沖制后,便得到一個完整的沖壓工件。在一副級進模中,可以連續(xù)完成沖裁、彎曲、拉深、成形等工序。一般來說,無論沖壓零件形狀怎樣復雜,沖壓工序怎樣多,均可用一副級進模沖制完成。本設計為沖孔、落料兩工位級進沖裁模。首先,分析工件的尺寸及精度要求等個方面的信息和要求,確定排樣圖和模具
2、型式及總體結構方案。然后根據(jù)工件分別計算和設計各2D零件草圖及修改、檢驗、校核。接著,設計擋料裝置及定位裝置,由于本設計工件的精度要求不高且生產(chǎn)為中、大批量故采用自動擋料裝置和定位銷裝置即可滿足要求。最后,檢驗無誤后,用Pro/E軟件生成3D實體進行動畫仿真,以校驗該設計的合理性及正確性。關鍵詞 連續(xù)模具;沖裁模;模具設計;仿真動畫;Pro/E-II-哈爾濱理工大學學士學位論文PunchingcutMulti-positionprogressivemoldDesignAnd3D-CADAnimationSimulationAbstractConsecutivemodules,alsokno
