首先我介紹一下什么是三輥卷板機?是什么是四輥卷板機?
無論是三輥卷板機還有四輥(gun)卷(juan)板機是一(yi)種將金(jin)屬板材卷(juan)彎成筒(tong)形(xing)、弧形(xing)或其(qi)它(ta)形(xing)狀工(gong)件的通用設備,構簡(jian)略(lve)、重量輕、易于制作修理(li)、出資少(shao)。此功用被大寬度的運用正(zheng)在(zai)造(zao)物、鍋爐蒸汽、化工(gong)、非金(jin)屬構造(zao)及(ji)機器(qi)打造(zao)等工(gong)作上。
三輥卷(juan)(juan)板機與四輥卷(juan)(juan)板機具有卷(juan)(juan)制O型、U型、多段R等不同(tong)形狀板材(cai)的功(gong)(gong)用(yong)。依據三點成圓的原理,使用(yong)工(gong)(gong)件(jian)相對方位改變(bian)和旋轉運動使板材(cai)發生接(jie)連的塑性變(bian)形,以取得預訂形狀的工(gong)(gong)件(jian)。因為結構簡略,功(gong)(gong)用(yong)牢靠,造價低(di)價,現已廣泛(fan)用(yong)于鍋爐、造船、石油、木匠、金(jin)屬結構及其它機械制作職業(ye)。
四輥卷(juan)板(ban)(ban)機(ji)適用于金屬板(ban)(ban)材(cai)的(de)彎曲成形(xing)工作(zuo)(zuo),可卷(juan)制圓(yuan)形(xing),弧(hu)形(xing)和一定范圍(wei)內的(de)錐形(xing)工件,并有板(ban)(ban)材(cai)端部預彎功能,剩余直邊小,工作(zuo)(zuo)效率高(gao),并可在該機(ji)上對金屬板(ban)(ban)材(cai)進行(xing)粗略校平。
1、三輥卷(juan)板(ban)(ban)機(ji):上輥在兩下(xia)輥中央對稱位置通過(guo)液壓缸內的液壓油作(zuo)用于活塞作(zuo)垂直升(sheng)降運動,通過(guo)主(zhu)減速機(ji)的末級齒輪(lun)帶動兩下(xia)輥齒輪(lun)嚙合作(zuo)旋轉運動,為卷(juan)制板(ban)(ban)材提供扭矩。而四(si)輥卷(juan)板(ban)(ban)機(ji)適用于金屬板(ban)(ban)材的彎(wan)曲成形(xing)工作(zuo),可卷(juan)制圓(yuan)形(xing),弧形(xing)和一定范(fan)圍內的錐形(xing)工件,并有(you)板(ban)(ban)材端部預彎(wan)功能,剩余直邊小,工作(zuo)效率(lv)高(gao),并可在該機(ji)上對金屬板(ban)(ban)材進行粗略校平。
2、三輥(gun)(gun)(gun)(gun)非(fei)對稱式卷(juan)板機(ji),上輥(gun)(gun)(gun)(gun)為主(zhu)(zhu)(zhu)傳(chuan)(chuan)動(dong),下(xia)(xia)輥(gun)(gun)(gun)(gun)垂直(zhi)(zhi)升(sheng)降運(yun)動(dong),以(yi)便(bian)夾緊板材(cai),并通過(guo)(guo)下(xia)(xia)輥(gun)(gun)(gun)(gun)齒(chi)輪(lun)(lun)與(yu)上輥(gun)(gun)(gun)(gun)齒(chi)輪(lun)(lun)嚙合,同時作(zuo)為主(zhu)(zhu)(zhu)傳(chuan)(chuan)動(dong);邊(bian)輥(gun)(gun)(gun)(gun)作(zuo)傾(qing)升(sheng)降運(yun)動(dong),具有預彎和卷(juan)圓雙重功能。結(jie)構緊湊,操作(zuo)維修方便(bian)。而(er)四輥(gun)(gun)(gun)(gun)卷(juan)板機(ji)上輥(gun)(gun)(gun)(gun)為主(zhu)(zhu)(zhu)傳(chuan)(chuan)動(dong),通過(guo)(guo)減速機(ji)、十字滑塊聯軸器(qi)與(yu)上輥(gun)(gun)(gun)(gun)相連(lian),為卷(juan)制板材(cai)提供扭矩;下(xia)(xia)輥(gun)(gun)(gun)(gun)作(zuo)垂直(zhi)(zhi)升(sheng)降運(yun)動(dong),通過(guo)(guo)減速機(ji)蝸(gua)(gua)(gua)桿(gan)蝸(gua)(gua)(gua)輪(lun)(lun)(傘齒(chi)輪(lun)(lun))付(fu)絲(si)(si)母絲(si)(si)桿(gan)付(fu)而(er)獲得,以(yi)便(bian)夾緊板材(cai),為機(ji)械傳(chuan)(chuan)動(dong);在下(xia)(xia)輥(gun)(gun)(gun)(gun)的兩側(ce)設有側(ce)輥(gun)(gun)(gun)(gun)并沿著機(ji)架導軌(gui)作(zuo)傾(qing)斜運(yun)動(dong),通過(guo)(guo)絲(si)(si)母絲(si)(si)桿(gan)蝸(gua)(gua)(gua)桿(gan)蝸(gua)(gua)(gua)輪(lun)(lun)(或傘齒(chi)輪(lun)(lun))付(fu)傳(chuan)(chuan)動(dong);四根工(gong)作(zuo)輥(gun)(gun)(gun)(gun)全部采用滾動(dong)軸承。
3、 四輥卷板機在工作時,上輥位置固定不動,下輥向上直線運動夾緊鋼板。兩側輥直線或弧線向上輥靠攏運動來調整卷筒的曲率半徑。四輥和三輥卷板機的輥子運動形式不同,但工作原理都一樣,都是利用三點定圓的原理來進行不同半徑的卷制。但四輥卷板機預彎的直邊和校圓的圓度都要比三輥好。
Whether it is three roll rolling machine and four roll rolling machine is a kind of metal plate rolling into cylinder, arc or other shape of the general equipment, simple structure, light weight, easy to make repair, less investment. This function is widely used in the creation, boiler steam, chemical, non-metallic structure and machine building work.
