style="text-indent:25px">連續(xù)模是一個(gè)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(gè)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，佛山防腐精密五金模具的用途和特點(diǎn)，以此定位進(jìn)行拉深、彎曲等成形工序。這種載體設(shè)計(jì)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，佛山防腐精密五金模具的用途和特點(diǎn)，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，佛山防腐精密五金模具的用途和特點(diǎn)，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。硬量合金頂針如鎢鋼頂針等，則能夠用來通較長較細(xì)的孔；佛山防腐精密五金模具的用途和特點(diǎn)</p><div

模具的疲勞斷裂性能主要取決于其強(qiáng)度、韌性、硬度、以及材料中夾雜物的含量。當(dāng)模具的工作溫度較高進(jìn)，會使硬度和強(qiáng)度下降，導(dǎo)致模具早期磨損或產(chǎn)生塑性變形而失效。因此，精密五金模具材料應(yīng)具有較高的抗回火穩(wěn)定性，以保證模具在工作溫度下，具有較高的硬度和強(qiáng)度。更高的出產(chǎn)功率。正是由于有了更長的運(yùn)用壽命，更快的加工速度，運(yùn)用揉捏絲錐能下降更換絲錐和待機(jī)的時(shí)刻，然后進(jìn)步出產(chǎn)功率。

lead）前端要求高平坦度，平坦部區(qū)域至少0.1 mm以上（大于金線直徑之三倍），因此必須采用壓印工程（coining）。 </p> <p> ② 各內(nèi)導(dǎo)腳間隔（Lead space）要求保持正確且均勻，壓印加工將使此間隔減小，故必須控制壓印深度及***導(dǎo)腳之橫向反曲（Twist）產(chǎn)生。 </p> <p> ③ 內(nèi)導(dǎo)腳之位置精度必須保持正確性以利后面工程wire bonding之確實(shí)黏著，對應(yīng)之策是先沖切內(nèi)導(dǎo)腳后沖切外導(dǎo)腳之沖壓加工順序要適正設(shè)計(jì)，以及沖壓加工程中設(shè)計(jì)調(diào)整站（correction Stage）以***沖壓加工時(shí)導(dǎo)線架導(dǎo)腳位置之偏移。 </p> <p> ④ 導(dǎo)線架之平面性要求高以利后面工程輸送時(shí)及wire bonding時(shí)之安定性及暢順性。對應(yīng)之策是沖切導(dǎo)腳時(shí)宜***其反曲量達(dá)**少程度及反曲方向一致，還有沖切加工前之導(dǎo)線架素材應(yīng)先施加應(yīng)力消除工程。 </p> <p> ⑤ 導(dǎo)線架之內(nèi)導(dǎo)腳扭曲或偏移等變形要求達(dá)到**小程度，以利后續(xù)工程之操作確實(shí)。解決之道在模具方面應(yīng)注意壓料板之強(qiáng)壓設(shè)計(jì)，設(shè)定**適的模具間隙及作用組件（沖頭及母模）之刃部要保持比較好狀態(tài)，模具導(dǎo)引裝置剛性高。 </p><p> ① 模具間隙 </p> <p> <br /> </p> <p> 導(dǎo)線架沖壓模具間隙為板厚之3～5％（銅系合金取3％，42合金取4～5％），至于壓料板與沖頭間隙將更小，宜小于模具間隙之50％。 </p> <p> <br /> </p> <p> ② 壓料板 </p> <p> <br /> </p> <p> 壓料板之壓料力要求高以***沖壓加工所產(chǎn)生的扭曲變形及改善導(dǎo)腳沖切面品質(zhì)，壓料位置宜集中于沖切荷重區(qū)域之附近（即punchguide部位），壓料板之壓料處采突出設(shè)計(jì)以提高局部的壓力使材料受到壓縮應(yīng)力而防止扭曲或反曲現(xiàn)象之發(fā)生。 </p> <p> <br /> </p> <p> ③ 沖切加工順序 </p> <p> <br /> </p> <p> 適正的沖切加工順序設(shè)計(jì)是改善導(dǎo)腳之沖切變形或扭曲的***方法，欲藉由后續(xù)的退火作業(yè)以矯正導(dǎo)腳之沖切變形或扭曲是難以達(dá)成的。下列是沖切順序考量之基本原則： </p> <p> <br /> </p> <p> A. 先沖切內(nèi)導(dǎo)腳，后沖切外導(dǎo)腳。 </p> <p> <br /> </p> <p> B. 先沖切短導(dǎo)腳，后沖切長導(dǎo)腳或先沖切長導(dǎo)腳后沖切短導(dǎo)腳之方式皆可，切記不可采用短導(dǎo)腳與長導(dǎo)腳相互交叉式?jīng)_切之配置形式。 </p> <p> <br /> 雖然材量是此中比力重要的一種，也并不是決議性因素。</p><div style="width:100%;text-align:

應(yīng)視模具工作零件的材料和要求的不同分別采用退火、正火或調(diào)質(zhì)等預(yù)備熱處理工藝, 以改善組織,消除鍛造毛坯的組織缺點(diǎn),改善加工工藝性。高碳合金模具鋼經(jīng)過適當(dāng)?shù)念A(yù)備熱處理可消除網(wǎng)狀二次滲碳體或鏈狀碳化物,使碳化物球化、細(xì)化,促進(jìn)碳化物分布均勻性。這樣有利于保證淬火、回火質(zhì)量,提高模具壽命。 </p> <p> 這是模具熱處理中的關(guān)鍵環(huán)節(jié)。若淬火加熱時(shí)產(chǎn)生過熱,不僅會使工件造成較大的脆性,而且在冷卻時(shí)容易引起變形和開裂,嚴(yán)重影響模具壽命。沖模淬火加熱時(shí)特別應(yīng)注意防止氧化和脫碳,應(yīng)嚴(yán)格控制熱處理工藝規(guī)范,在條件允許的情況下,可采用真空熱處理。淬火后應(yīng)及時(shí)回火,并根據(jù)技術(shù)要求采用不同的回火工藝。

style="text-indent:25px">連續(xù)模沖壓工件，必須解決條料的準(zhǔn)確定位問題，保證連續(xù)模的步距一致，才有可能沖出合格的制件。連續(xù)模中，常用的定位裝置有固定擋料銷、導(dǎo)正銷、導(dǎo)板、側(cè)刃等幾種形式。沖壓時(shí)，先用固定擋料銷初步定位，落料時(shí)用裝于模內(nèi)的導(dǎo)正銷保證條料的正確定位。側(cè)刃是用以控制每步條料送進(jìn)的距離。側(cè)刃長度應(yīng)等于步距長加0.05-0.5mm，具體視材料厚度決定。了控制送料步距，連續(xù)模必須有較好的定位裝置。常用的定位裝置有導(dǎo)正銷、初始擋料銷、側(cè)刃、導(dǎo)銷等，其中導(dǎo)正銷是連續(xù)模中應(yīng)用較廣的一種精密定位方法，它與誤送檢測傳感器使用還可以報(bào)警停機(jī)，起保護(hù)模具的作用，因此，在連續(xù)沖壓模中經(jīng)常使用。在高精度的連續(xù)沖壓模中，常用沖預(yù)沖孔，然后在各工步采用導(dǎo)正銷對卷料導(dǎo)正的方法。這時(shí)，所用導(dǎo)正銷的直徑通常是∮1.2~6mm。必須注意導(dǎo)正銷的長度不能過大，進(jìn)入導(dǎo)正孔的長度也不能過大，否則會引起模具送料不暢，帶料等情況。為此，連續(xù)沖壓模的導(dǎo)正銷直身長度應(yīng)為：導(dǎo)正銷固定模板的厚度+1個(gè)材料的厚。佛山防腐精密五金模具的用途和特點(diǎn)</p><p
