螺旋葉片成(cheng)形機屬于專業設(she)備,加工片(pian)式螺旋(xuan)葉片(pian)。成(cheng)形原理是由液壓(ya)系統(tong)推動模(mo)具(ju)反復運動,2個模(mo)具(ju)互相(xiang)功(gong)效,將鋼板擠壓(ya)變形,稱為螺旋(xuan)葉片(pian)。此設(she)備結構緊湊(cou),操作簡便。
螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)成(cheng)(cheng)形(xing)機根據(ju)更(geng)換模(mo)(mo)具和調整行程來加工相(xiang)對應(ying)螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian),螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)的(de)(de)螺(luo)(luo)距(ju)是螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)的(de)(de)重(zhong)要指(zhi)標,控制(zhi)(zhi)牙距(ju)的(de)(de)辦(ban)法也有兩(liang)種,一種是由更(geng)換模(mo)(mo)具,不(bu)同的(de)(de)模(mo)(mo)具,傾(qing)斜程度不(bu)同,做出的(de)(de)螺(luo)(luo)旋(xuan)(xuan)牙距(ju)便(bian)會(hui)不(bu)同;另一種方(fang)式是,改變(bian)(bian)(bian)模(mo)(mo)具之(zhi)間的(de)(de)行程,使模(mo)(mo)具之(zhi)間間隙改變(bian)(bian)(bian),進而改變(bian)(bian)(bian)螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)的(de)(de)牙距(ju)。在螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)成(cheng)(cheng)形(xing)機的(de)(de)下邊,設(she)置有2個限(xian)位(wei)開(kai)(kai)關(guan),前(qian)(qian)后(hou)各一個,活動(dong)(dong)模(mo)(mo)具板(ban)由液壓系(xi)統控制(zhi)(zhi)前(qian)(qian)后(hou)挪(nuo)動(dong)(dong),當移到(dao)(dao)前(qian)(qian)面限(xian)位(wei)開(kai)(kai)關(guan)時,碰撞塊觸碰到(dao)(dao)限(xian)位(wei)開(kai)(kai)關(guan),限(xian)位(wei)開(kai)(kai)關(guan)動(dong)(dong)作(zuo),根據(ju)電源線傳送信號給控制(zhi)(zhi)系(xi)統,活動(dong)(dong)模(mo)(mo)具板(ban)改變(bian)(bian)(bian)運(yun)(yun)動(dong)(dong)方(fang)向(xiang),向(xiang)后(hou)才運(yun)(yun)動(dong)(dong);當運(yun)(yun)動(dong)(dong)到(dao)(dao)后(hou)面限(xian)位(wei)開(kai)(kai)關(guan)是,碰撞塊觸碰到(dao)(dao)限(xian)位(wei)開(kai)(kai)關(guan),限(xian)位(wei)開(kai)(kai)關(guan)動(dong)(dong)作(zuo),根據(ju)電源線傳送信號給控制(zhi)(zhi)系(xi)統,活動(dong)(dong)模(mo)(mo)具板(ban)改變(bian)(bian)(bian)運(yun)(yun)動(dong)(dong)方(fang)向(xiang),向(xiang)前(qian)(qian)方(fang)運(yun)(yun)動(dong)(dong)。如(ru)此反(fan)復運(yun)(yun)動(dong)(dong),多個下以后(hou),一個完(wan)整的(de)(de)螺(luo)(luo)旋(xuan)(xuan)葉(xie)(xie)片(pian)加工完(wan)成(cheng)(cheng)。
螺(luo)旋(xuan)葉片成形(xing)機(ji)加工薄(bo)厚(hou)較大(da)的螺(luo)旋(xuan)葉片時(shi),2個模具(ju)間的距離(li)要增(zeng)大(da),間距比鋼板厚(hou)度大(da)2mm上下(xia),空負載運行,當活動(dong)模具(ju)板靠近前面模具(ju)時(shi),終止動(dong)作,測量距離(li),隨后調(diao)節限位(wei)開關(guan)位(wei)置(zhi),使碰撞塊到此位(wei)置(zhi)能(neng)自動(dong)回(hui)到為準。一樣(yang),后邊的限位(wei)開關(guan)也同樣(yang)操作,確保螺(luo)旋(xuan)葉片在擠(ji)壓以后能(neng)順能(neng)的選配即可,距離(li)太遠則會影響工作的效率。
