設(shè)計(jì)的沖壓件必須形狀簡(jiǎn)單，結(jié)構(gòu)合理，以有利于簡(jiǎn)化模具結(jié)構(gòu)、簡(jiǎn)化工序數(shù)量，即用少、簡(jiǎn)單的沖壓工序完成整個(gè)零件的加工，減少再用其他方法加工，并有利于沖壓操作，便于組織實(shí)現(xiàn)機(jī)械化與自動(dòng)化生產(chǎn)，以高勞動(dòng)生產(chǎn)率。

設(shè)計(jì)的沖壓件，在保證能正常使用情況下，盡量使尺寸精度等級(jí)及表面粗糙度等級(jí)要求低一些，并有利于產(chǎn)品的互換，減少?gòu)U品、保證產(chǎn)品質(zhì)量穩(wěn)定。

設(shè)計(jì)的沖壓件，應(yīng)有利于盡可能使用現(xiàn)有設(shè)備、工藝裝備以及工藝流程對(duì)其進(jìn)行加工，并有利于沖模使用壽命的延長(zhǎng)。

凸模刃口端部修出斜面或弧形。這是減緩沖裁力的有效方法。減緩沖裁力，即可減輕對(duì)凹模側(cè)材料的拉伸力，從而達(dá)到抑制沖壓件產(chǎn)生翻料、扭曲的效果。

The end of the punch is repaired with a bevel or arc. This  an effective way to slow down the blanking force. By reducing the force of buffer, the tensile force of the side material of the die can be reduced, so that the stamping and twisting effect can be suppressed.

五金沖壓模具的安裝是否正確合理，不僅影響五金沖壓件的產(chǎn)品質(zhì)量和精度，還會(huì)影響模具的工作壽命及生產(chǎn)安全。并且熟練掌握沖壓模具的安裝也是每個(gè)沖壓工應(yīng)該掌握的技巧。

Whether the installation of the metal stamping die is correct and reasonable, not only affects the quality and precision of the metal stamping parts, but also affects the working life and production safety of the die. And skilled in stamping die installation is also a skill that every stamping worker should master.

檢查、核對(duì)模具和沖壓機(jī)床。在安裝模具前，要確認(rèn)沖壓機(jī)床為沖壓工藝的型號(hào)，并檢查模具的尺寸、工作要求是否與沖壓機(jī)床的技術(shù)參數(shù)（裝模高度、滑塊行程等）相匹配，沖壓機(jī)床的狀態(tài)足否良好。

Check and check die and stamping machine. Before installing the mould, it is necessary to confirm that the stamping machine is the designated type of the stamping process, and check the size of the die and the work requirements to match the technical parameters of the designated stamping machine (the height of the die, the slider stroke, etc.), and the state of the stamping machine is good or not.
