設(shè)計的沖壓件必須形狀簡單，結(jié)構(gòu)合理，以有利于簡化模具結(jié)構(gòu)、簡化工序數(shù)量，即用少、簡單的沖壓工序完成整個零件的加工，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)械化與自動化生產(chǎn)，以高勞動生產(chǎn)率。

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

設(shè)計的沖壓件，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其進(jìn)行加工，并有利于沖模使用壽命的延長。

手鋸鋸削的注意事項(xiàng)

鋸條的松緊要合適，且鋸割時壓力不能太大，以防折斷傷人；

當(dāng)鋸縫歪斜時，不可急于糾正，而需要慢慢地逐步糾正。

Notice of hand saw cutting

The tightness of the saw blade should be suitable, and the pressure should not be too large during sawing, so as to prevent breaking and hurting people.

When the SAW seam is skewed, it can not be corrected in a hurry, but it needs to be corrected gradually.

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.
