style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="麗水折彎剪板加工廠有哪些,折彎剪板加工"

V形槽寬度的選擇主要是根據(jù)板厚，V形槽寬度越大，所需折彎壓力越小，一般情況下，較薄板料常取V＝6t，其中V為下模V形槽寬度；t為板厚。普通下模V形槽寬度與板厚的選定見表1。 </p> <p> 表1 普通下模V形槽寬度與板厚的選定 </p> <p> 另外還要考慮零件折彎尺寸。當(dāng)尺寸較小時(shí)，若下模V形槽寬度較大，折彎時(shí)板料頂端無法與V形槽兩肩同時(shí)接觸受力，會(huì)滑入V形槽中，導(dǎo)致無法成形。 </p> <p> （2）下模形狀的選擇下模一般分為單槽下模和雙槽下模。單槽下模使用靈活方便，雙槽下模穩(wěn)定性較好，應(yīng)根據(jù)實(shí)際情況來決定適用的下模。另外還有一些特殊形狀的下模，例如段差模、壓邊拍平模以及折圓弧的彈性橡膠下模等。 </p> <p> （3）下模的V形槽角度 V形槽按照角度分為直角下模和銳角下模，銳角下模常用的角度是30°和45°，直角下模常用的角度有88°和90°，標(biāo)準(zhǔn)下模角度為88°，其選擇是根據(jù)材料的性質(zhì)以及回彈量來確定的。當(dāng)材料抗拉強(qiáng)度較大以及回彈量較大時(shí)，例如不銹鋼或者較薄的板料，應(yīng)選用88°下模；普通低碳鋼和銅等較軟的材料可選用90°下模。 </p><p style="text-indent:25px">大型剪板加工是應(yīng)用比較普遍的一種加工工藝，它能剪切各種厚度的鋼板材料。常用的大型剪板加工設(shè)備分為平剪、滾剪及震動(dòng)剪3種類型。其中平剪機(jī)是使用較多的。剪切厚度小于10mm的剪板機(jī)多為機(jī)械傳動(dòng)，大于10mm的為液壓動(dòng)傳動(dòng)。一般用腳踏或按鈕操縱進(jìn)行單次或連續(xù)剪切金屬。在進(jìn)行大型剪板加工之前，要認(rèn)真檢查剪板機(jī)各部是否正常，電氣設(shè)備是否完好，潤滑系統(tǒng)是否暢通；清理臺(tái)面及其周圍放置有工具、量具等雜物以及邊角廢料。不要獨(dú)自1人操作剪板機(jī)，應(yīng)由2—3人協(xié)調(diào)進(jìn)行送料、控制尺寸精度及取料等，并確定由1人統(tǒng)一指揮。要根據(jù)規(guī)定的大型剪板加工厚度，調(diào)整剪板機(jī)的剪刀間隙；不準(zhǔn)同時(shí)剪切2種不同規(guī)格、不同材質(zhì)的板料；不得疊料剪切。剪切的板料要求表面平整，不準(zhǔn)剪切無法壓緊的較窄板料。在剪板折彎一體機(jī)油箱中加入L-HL46號(hào)機(jī)械油（油液必須清潔）。</p><div
