折(zhe)彎機是一(yi)種能夠(gou)對(dui)薄板(ban)(ban)(ban)(ban)進(jin)行(xing)折(zhe)彎的(de)機器，其結構主要包(bao)括支(zhi)架、工作(zuo)臺(tai)和(he)夾緊板(ban)(ban)(ban)(ban)，工作(zuo)臺(tai)置于支(zhi)架上，工作(zuo)臺(tai)由底(di)(di)座(zuo)和(he)壓板(ban)(ban)(ban)(ban)構成(cheng)，底(di)(di)座(zuo)通(tong)(tong)(tong)過鉸鏈與夾緊板(ban)(ban)(ban)(ban)相連，底(di)(di)座(zuo)由座(zuo)殼、線(xian)(xian)圈和(he)蓋(gai)板(ban)(ban)(ban)(ban)組(zu)成(cheng)，線(xian)(xian)圈置于座(zuo)殼的(de)凹陷內(nei)，凹陷頂部覆有蓋(gai)板(ban)(ban)(ban)(ban)。使用(yong)時由導線(xian)(xian)對(dui)線(xian)(xian)圈通(tong)(tong)(tong)電(dian)(dian)，通(tong)(tong)(tong)電(dian)(dian)后對(dui)壓板(ban)(ban)(ban)(ban)產生引力，從而實(shi)現對(dui)壓板(ban)(ban)(ban)(ban)和(he)底(di)(di)座(zuo)之間薄板(ban)(ban)(ban)(ban)的(de)夾持。由于采(cai)用(yong)了電(dian)(dian)磁力夾持，使得(de)壓板(ban)(ban)(ban)(ban)可(ke)以(yi)做成(cheng)多種工件要求(qiu)，而且可(ke)對(dui)有側壁的(de)工件進(jin)行(xing)加工，操作(zuo)上也十分簡便(bian)。

折彎(wan)機(ji)(ji)使(shi)用(yong)時由導線(xian)對(dui)(dui)線(xian)圈通(tong)電，通(tong)電后(hou)對(dui)(dui)壓板(ban)產生引(yin)力，從而(er)實現對(dui)(dui)壓板(ban)和底(di)座(zuo)之(zhi)間薄板(ban)的夾持。由于采(cai)用(yong)了電磁力夾持，使(shi)得壓板(ban)可以(yi)做成多種工(gong)件(jian)(jian)要求，而(er)且可對(dui)(dui)有(you)側壁的工(gong)件(jian)(jian)進(jin)行加工(gong)。折彎(wan)機(ji)(ji)可以(yi)通(tong)過更(geng)換(huan)折彎(wan)機(ji)(ji)模具，從而(er)滿足各種工(gong)件(jian)(jian)需(xu)求。
