1、鏈板片沖孔落料復(fù)合模設(shè)計摘要本課題為鏈板片沖孔落料復(fù)合模的設(shè)計,本文介紹的模具實例結(jié)構(gòu)簡單實用,使用方便可靠。本套模具的設(shè)計不是以復(fù)雜模具的設(shè)計為主,而主要是對模具設(shè)計知識的系統(tǒng)學(xué)習(xí)和設(shè)計的練習(xí),以達到掌握沖壓模具設(shè)計的基本技能的目的。首先,對零件做整體的分析。包括:材料的使用、精度的要求、工序的要求以及成本的要求等。為了降低成本,對排樣方式進行了合理的設(shè)計;其次,對零件整體進行工藝設(shè)計。通過工藝目的的設(shè)計、工序的順序設(shè)計、壓力機的選擇等來實現(xiàn)所要達到的要求;再次,想要保證制件精度的要求,就要考慮模具刃口尺寸的計
2、算。因為刃口是沖制工件的主要工作部分,刃口處的精度就決定了制件的精度,就必須根據(jù)公差來進行精確計算。最后,根據(jù)計算出的模具刃口尺寸設(shè)計出相應(yīng)的凸凹模,并且查找資料選擇冷沖壓模的標(biāo)準(zhǔn)零件,符合標(biāo)準(zhǔn)后,就把凸凹模與其它各零部件進行總體裝配。在確定了模具體閉合高度后,選出合適的壓力機在調(diào)試校驗后并進行試沖加工,以達到符合的標(biāo)準(zhǔn),最終完成鏈板片的加工。關(guān)鍵詞:復(fù)合模,沖壓工藝,模具設(shè)計,沖孔落料44ThechainplatepunchingblankingcompoundmolddesignAbstractThetopi
