內(nèi)容提要
本設計主要圍繞沖壓模具設計展開，設計宗旨為降低生產(chǎn)成本，提高生產(chǎn)效率，提高模具壽命，而且要求操作方便，維修簡單。
本次設計的課題是短臂沖壓成形，其形狀比較簡單，精度要求不高，精度等級使用IT14即可，整個設計過程中包括模具的結(jié)構(gòu)分析與主要零件的計算。根據(jù)模具尺寸選擇安裝相應的模架，在設計時對模具的質(zhì)量、模具的壽命、生產(chǎn)周期及生產(chǎn)成本等因素進行了全面仔細的分析。總的設計過程為從零件工藝的分析到確定工藝方案然后到模具的設計和裝配。通過本次設計，靈活運用所學知識，加深對模具設計、機械加工、公差、熱處理等內(nèi)容的掌握，提高了獨立解決問題的能力。
Abstract
The main contents of this design is about the design of the stamping dies , its aim at lower the production cost , increasing production efficiency ,lift the molding tool life span and request for operate convenience , fix briefly and easily .
This design is Short arm stamping forming, its shape is quite simple, the precision request is not high, the precision class uses IT14 is may,the whole design process include the calculation of the structure analytical and main spare parts of molding tool . According to the molding tool size , choice install an accordingly homologous mold, while designing the life span of the molding , the economy of the molding tool, produce period and production cost etc.are should carried on under overall careful analysis.Total design process for analyze part process then arrive sure the process program and finally the design and assembly of the molding.Through this design, nimble utilization the knowledge of studies, deepen understand the content of the mold design, the machine-finishing, the tolerance, the heat treatment and exercise the ability of solve the question independently .
