style="text-indent:25px">連續(xù)模是一個產(chǎn)品連續(xù)沖壓的過程，特別是遇到?jīng)_孔及切邊較多的情況，沖壓過程中為避免產(chǎn)品壓傷，及模具的穩(wěn)定性，通常需做防跳廢料結(jié)構(gòu)。主要從以下幾點(diǎn)著手：1.沖頭做成異形，可以增加廢料在刀口上的附著力；2.沖頭加吹氣孔；3.刀口做V型或燕尾卡料形式;4.合理放沖裁間隙，減少跳料;5.模內(nèi)吸廢料裝置。連續(xù)模中的各工序的工件是靠帶料的搭邊余料進(jìn)行傳遞的，制件一般在***的落料工序完成與帶料分離。這個搭邊稱為連續(xù)模的載體。在連續(xù)模中，常見的載體形式有：邊料載體、中間載體、雙面載體、單邊載體等形式。邊料載體是利用在工件的邊余料上沖出導(dǎo)正孔，以此定位進(jìn)行拉深、彎曲等成形工序。這種載體設(shè)計簡單、可靠、節(jié)省材料，因此應(yīng)用很廣。中間載體是沿帶料，在工件四周切去大部分材料，只在帶料寬度方向的中部留少許連接材料，這種載體剛性不佳，連續(xù)沖壓穩(wěn)定性不夠好。雙面載體是在帶料的兩側(cè)留少撬材料，載體剛性好不易變形，常用于薄料大進(jìn)距工件的連續(xù)沖壓。單側(cè)載體只在帶料的單側(cè)留少許材料，這種載體剛性較差，只能用于料厚較大、進(jìn)距較小的工件的連續(xù)沖壓。沖頭是安拆正在沖壓模具上的金屬零件，應(yīng)用于取質(zhì)料的間接接觸，使質(zhì)料發(fā)作形變、裁切質(zhì)料。汕頭耐磨精密五金模具廠</p><p
