合理的模具設(shè)計(jì)。在級進(jìn)模中,下料順序的安排有可能影響到?jīng)_壓件成形的精度。針對沖壓件細(xì)小部位的下料,一般先安排較大面積之沖切下料,再安排較小面積的沖切下料,以減輕沖裁力對沖壓件成形的影響。
Reasonable mold design. In progressive die, the order of blanking sequence may affect the accuracy of stamping forming. In order to reduce the impact of punching parts, the punching and cutting blanking of small area is arranged in the light of the blanking of the small parts of the stamping parts.
設(shè)計(jì)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(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(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其進(jìn)行加工,并有利于沖模使用壽命的延長。
槽鋼的鋸削:槽鋼的鋸削與扁鋼一樣,但是要分二次從寬邊面往下鋸,不能在一個(gè)面上往下鋸,應(yīng)盡量做到在長的鋸縫口上起鋸,因此工件必須多次改變夾持的位置。
Channel steel sawing: the channel sawing of the channel steel is the same as that of the flat steel, but it must be sawed down two times from the wide side, and can not be sawed down on one surface, and should be sawed on the long saw mouth as far as so the of the clamping must be changed many times.
