1、輥彎成形的工作原理:輥彎機一般分為立式輥彎機和臥式輥彎機。鋁合金軌道廠家介紹(shao)立式(shi)輥彎機(ji)(ji)上(shang)料操作方(fang)便,對于(yu)長(chang)大工(gong)件則(ze)宜采用臥式(shi)。輥彎機(ji)(ji)各軸工(gong)藝位置均由(you)伺服電動(dong)機(ji)(ji)精確控制,液壓馬達系統驅動(dong)各軸的聯動(dong),通過可編程序(xu)控制器(PLC)控制伺服電動(dong)機(ji)(ji)進行動(dong)作。
2、工(gong)藝特(te)點:輥彎機一(yi)般(ban)多數(shu)用來單(dan)圓(yuan)弧工(gong)件的(de)制(zhi)作(zuo),模具(ju)制(zhi)作(zuo)周期短,投入成本低(di),操作(zuo)簡(jian)單(dan)。輥彎工(gong)藝難易程度(du)取決于彎形材料(liao)的(de)截面形狀(zhuang),輥輪模具(ju)設(she)計是工(gong)件成形技術的(de)關(guan)鍵,一(yi)般(ban)模具(ju)材料(liao)選(xuan)用45調質(zhi)鋼或模具(ju)鋼經車(che)床車(che)削而成,通(tong)過熱處理及表面鍍鉻等工(gong)藝獲得(de)模具(ju)硬度(du)和表面粗糙(cao)度(du)要求。
3、輥彎(wan)(wan)設(she)(she)備(bei)(bei)是(shi)否(fou)(fou)滿(man)(man)足(zu)輥彎(wan)(wan)工件(jian)的工藝要求(qiu),需滿(man)(man)足(zu)的條件(jian):輥軸(zhou)長度(du)(du)是(shi)否(fou)(fou)滿(man)(man)足(zu)材(cai)料(liao)的寬(kuan)度(du)(du)尺寸。設(she)(she)備(bei)(bei)輥彎(wan)(wan)最小彎(wan)(wan)弧(hu)半徑是(shi)否(fou)(fou)大于(yu)工件(jian)的最小弧(hu)度(du)(du)。設(she)(she)備(bei)(bei)壓(ya)力是(shi)否(fou)(fou)大于(yu)材(cai)料(liao)輥彎(wan)(wan)成(cheng)(cheng)形(xing)力。壓(ya)彎(wan)(wan)成(cheng)(cheng)形(xing)是(shi)利用(yong)液壓(ya)壓(ya)力機對材(cai)料(liao)施加壓(ya)力,通過壓(ya)彎(wan)(wan)模具(ju)對材(cai)料(liao)產生彎(wan)(wan)矩,使(shi)材(cai)料(liao)發(fa)生彎(wan)(wan)曲形(xing)成(cheng)(cheng)一定的角度(du)(du)和曲率。
4、鋁合金(jin)型(xing)(xing)材折彎(wan)(wan)(wan)件(jian)L形(xing)及S形(xing)均可以采用壓(ya)(ya)彎(wan)(wan)(wan)工(gong)藝,由于型(xing)(xing)材斷(duan)面(mian)及形(xing)狀各異,各種壓(ya)(ya)彎(wan)(wan)(wan)件(jian)壓(ya)(ya)彎(wan)(wan)(wan)模具(ju)反彈(dan)量設計(ji)不(bu)一而同,需要(yao)經過(guo)不(bu)斷(duan)的(de)壓(ya)(ya)彎(wan)(wan)(wan)工(gong)藝試驗摸(mo)索反彈(dan)量并經幾(ji)次(ci)修模得到(dao)合理(li)的(de)模具(ju)壓(ya)(ya)彎(wan)(wan)(wan)形(xing)面(mian)。壓(ya)(ya)彎(wan)(wan)(wan)模具(ju)的(de)設計(ji),要(yao)充分考慮(lv)材料(liao)的(de)變形(xing)趨(qu)勢和反彈(dan)量。由于鋁合金(jin)型(xing)(xing)材具(ju)有型(xing)(xing)腔(qiang)空(kong)心結構,合理(li)的(de)填料(liao)選用是壓(ya)(ya)彎(wan)(wan)(wan)成形(xing)的(de)關鍵。對于斷(duan)面(mian)形(xing)狀不(bu)對稱型(xing)(xing)材,壓(ya)(ya)彎(wan)(wan)(wan)時(shi)要(yao)充分考慮(lv)防止(zhi)側彎(wan)(wan)(wan)的(de)有效(xiao)措(cuo)施。
