摘要
本次設(shè)計(jì)了一套沖壓模具。首先要對(duì)沖壓模具進(jìn)行工藝分析,經(jīng)過(guò)工藝分析和對(duì)比確定模具架及壓力機(jī),確定壓力機(jī)的型號(hào)。再分析對(duì)沖壓件加工的模具適用類型選擇所需設(shè)計(jì)的模具。得出將設(shè)計(jì)的模具類型后將模具的各工作零部件設(shè)計(jì)過(guò)程表達(dá)出來(lái)。
在說(shuō)明書(shū)中第一部分,主要敘述了沖壓模具的發(fā)展?fàn)顩r,說(shuō)明了沖壓模具的重要性與本次設(shè)計(jì)的意義,對(duì)沖壓件的工藝分析,工藝方案的確定。通過(guò),對(duì)零件排樣圖的設(shè)計(jì),完成了材料利用率的計(jì)算。再進(jìn)行沖裁工藝力的計(jì)算和沖裁模工作部分的設(shè)計(jì)計(jì)算。最后對(duì)主要零部件的設(shè)計(jì)和標(biāo)準(zhǔn)件的選擇,為本次設(shè)計(jì)模具的繪制和模具的成形提供依據(jù),以及為裝配圖各尺寸提供依據(jù)。通過(guò)前面的設(shè)計(jì)方案畫(huà)出模具各零件圖和裝配圖。

Abstract
A molding tool for designing a set ofly hurtling bore, falling anticipating.Want to proceed the craft analysis to the washer first, analyze through craft with contrast certain molding tool a model number for and pressure machine, making sure pressure machine.Analyze again to wash to press a molding tool for processing apply the type the choice a molding tool for needing design.Get a molding tool for will designing type empress expresses out each work zero parts design process of the molding tool.
In text file the first part, described to wash the development condition that press the molding tool primarily, explain to wash the importance that press the molding tool and the meaning of this design, to craft that washing and pressing the piece analyzes, the craft project really settles.Pass, line up the design of the kind diagram to the spare parts, complete the calculation of the material utilization.Proceed again the calculation that wash cut the craft dint with wash to cut mold work part of designs calculation.Finally to the design of the main the parts of zero with the choice of the standard piece, draw for this design molding tool to take shape the offering with the molding tool according to, and for assemble each size of diagram offering according to.The design project passing before draws an each spare parts of molding tool diagram with assemble the diagram.
