模芯定位孔因對模芯頻繁多次的組合而產生磨損,造成組裝后間隙偏大(組裝后產生松動)或間隙不均(產生定位偏差)均會造成沖切后斷面形狀變差,凸模易斷,產生毛刺等,可透過對沖切后斷面狀況檢查,作適當的間隙調整.間隙小時,斷面較少,間隙大時,斷面較多且毛邊較大,以移位的方式來獲得合理的間隙,調整好后,應作適當記錄,也可在凹模邊作記號等,以便后續(xù)維護作業(yè).日常生產應注意收集保存原始的模具較佳狀況時的料帶,如后續(xù)生產不順暢或模具產生變異時,可作為模具檢修的參考.另外,輔助系統(tǒng)如頂料銷是否磨損,是否能頂料,導正釘及襯套是否已磨損,應注意檢查并維護。</p><p> 沖壓生產中**常用的材料是金屬材料（包括黑色金屬和有色金屬），但有時也用非金屬材料。其中黑色金屬主要有普通碳素結構鋼、質量碳素結構鋼、合金結構鋼、碳素工具鋼、不銹鋼、電工硅鋼等；有色金屬主要有純銅、黃銅、青銅、鋁等；非金屬材料有紙板、層壓板、橡膠板、塑料板、纖維板和云母等。 </p> <p> <br /> </p> <p> 沖壓用金屬材料的供應狀態(tài)一般是各種規(guī)格的板料和帶料。板料可用于工程模的生產，帶料（卷料）用于連續(xù)模的生產，也可以用于工程模的生產。板料的尺寸較大，可用于大型零件的沖壓，也可以將板料按排樣尺寸剪裁成條料后用于中小型零件的沖壓；帶料（又稱卷料）有各種規(guī)格的寬度，展開長度可達幾十米，成卷狀供應，適應于連續(xù)模大批量生產的自動送料。 </p> <p> <br

硬度是影響耐磨性的主要因素。一般情況下，模具零件的硬度越高，磨損量越小，耐磨性也越好。另外，耐磨性還與材料中碳化物的種類、數量、形態(tài)、大小及分布有關。模具的工作條件大多十分惡劣，有些常承受較大的沖擊負荷，從而導致脆性斷裂。為防止模具零件在工作時突然脆斷，精密五金模具要具有較高的強度和韌性。 </p> <p> 模具的韌性主要取決于材料的含碳量、晶粒度及組織狀態(tài)-精密模具制造。

style="text-indent:25px">連續(xù)模是一個產品連續(xù)沖壓的過程，特別是遇到沖孔及切邊較多的情況，沖壓過程中為避免產品壓傷，及模具的穩(wěn)定性，通常需做防跳廢料結構。主要從以下幾點著手：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正孔，以此定位進行拉深、彎曲等成形工序。這種載體設計簡單、可靠、節(jié)省材料，因此應用很廣。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留少撬材料，載體剛性好不易變形，常用于薄料大進距工件的連續(xù)沖壓。單側載體只在帶料的單側留少許材料，這種載體剛性較差，只能用于料厚較大、進距較小的工件的連續(xù)沖壓。龍華金屬精密五金模具廠家</p><p
