三輥卷板機

有(you)機(ji)械(xie)(xie)式和液壓(ya)式：機(ji)械(xie)(xie)式三輥(gun)卷(juan)板(ban)(ban)機(ji)分為對稱和非對稱。可將金(jin)屬板(ban)(ban)材(cai)卷(juan)成圓形(xing)、弧(hu)形(xing)和一定范圍內的(de)錐形(xing)工(gong)(gong)(gong)件(jian)，其(qi)工(gong)(gong)(gong)作(zuo)原理是通(tong)過(guo)液壓(ya)力、機(ji)械(xie)(xie)力等外力的(de)作(zuo)用，使(shi)工(gong)(gong)(gong)作(zuo)輥(gun)運動，從而(er)使(shi)板(ban)(ban)材(cai)壓(ya)彎(wan)或卷(juan)彎(wan)成形(xing)；根據不同(tong)形(xing)狀(zhuang)的(de)工(gong)(gong)(gong)作(zuo)輥(gun)的(de)旋(xuan)轉運動以及位置變化，可以加工(gong)(gong)(gong)出橢圓形(xing)件(jian)、弧(hu)形(xing)件(jian)、筒形(xing)件(jian)等零件(jian)。適用于卷(juan)板(ban)(ban)厚(hou)度在50mm以上的(de)大型卷(juan)板(ban)(ban)機(ji)，兩下(xia)(xia)輥(gun)下(xia)(xia)部(bu)增加了一排固定托(tuo)輥(gun)，縮(suo)短兩下(xia)(xia)輥(gun)跨距(ju)，從而(er)提(ti)高卷(juan)制工(gong)(gong)(gong)件(jian)精度及機(ji)器(qi)整體性能。
