板厚卷(juan)制及組對新技術,實際上(shang)例(li)如詳細操作(zuo)步驟:
1)上上下料(liao):按(an)照(zhao)其(qi)寸(cun)尺(chi)規格標準要求、選擇系統軟件抑制智能焰火切除機下出卷制每段筒節的扇形角鋼板才(cai),上上下料(liao)寸(cun)尺(chi)規格偏移間距趨(qu)勢測量誤(wu)差為0~1.5mm、板寬之差≤1.5mm、對角線(xian)之差≤2.5mm。
2)開坡口(kou)(kou):開的板材的縱(zong)縫與(yu)環縫聯接坡口(kou)(kou),選取磨光機拋(pao)光坡口(kou)(kou)表面,并清洗坡口(kou)(kou)付(fu)近30mm范(fan)圍圖內的異物。
3)預彎(wan):將事前調整好的屈(qu)曲(qu)(qu)(qu)類別送至四(si)輥(gun)卷板機(ji)(ji)器上下兩輥(gun)中(zhong)間,并主要包括作(zuo)為支撐將屈(qu)曲(qu)(qu)(qu)類別一定于3個(ge)側輥(gun)頂(ding)部,將需預彎(wan)的原材(cai)料(liao)的兩端送至卷板機(ji)(ji)并擺放在于屈(qu)曲(qu)(qu)(qu)類別上,下壓(ya)上輥(gun)使(shi)原材(cai)料(liao)生成蠕(ru)變扭曲(qu)(qu)(qu),再對(dui)原材(cai)料(liao)的另(ling)兩端使(shi)用(yong)預彎(wan),將原材(cai)料(liao)的兩端均預彎(wan)到調整的曲(qu)(qu)(qu)率轉彎(wan)半徑(jing)。
