折(zhe)彎機(ji)是一(yi)種(zhong)能夠(gou)對薄板(ban)(ban)進(jin)行(xing)折(zhe)彎的(de)機(ji)器(qi)，其(qi)結(jie)構主要(yao)包括支(zhi)架(jia)、工(gong)作(zuo)臺(tai)和(he)夾(jia)緊板(ban)(ban)，工(gong)作(zuo)臺(tai)置(zhi)于支(zhi)架(jia)上，工(gong)作(zuo)臺(tai)由底(di)座(zuo)和(he)壓(ya)板(ban)(ban)構成，底(di)座(zuo)通過鉸鏈(lian)與夾(jia)緊板(ban)(ban)相連，底(di)座(zuo)由座(zuo)殼、線(xian)圈(quan)和(he)蓋(gai)板(ban)(ban)組(zu)成，線(xian)圈(quan)置(zhi)于座(zuo)殼的(de)凹(ao)陷內，凹(ao)陷頂部覆有(you)蓋(gai)板(ban)(ban)。使用(yong)時(shi)由導線(xian)對線(xian)圈(quan)通電，通電后(hou)對壓(ya)板(ban)(ban)產生引(yin)力(li)，從而實(shi)現對壓(ya)板(ban)(ban)和(he)底(di)座(zuo)之間薄板(ban)(ban)的(de)夾(jia)持(chi)。由于采用(yong)了電磁力(li)夾(jia)持(chi)，使得壓(ya)板(ban)(ban)可以做成多種(zhong)工(gong)件(jian)要(yao)求，而且可對有(you)側壁的(de)工(gong)件(jian)進(jin)行(xing)加工(gong)，操(cao)作(zuo)上也十分簡便。

折彎(wan)機使用(yong)時由(you)導線(xian)對(dui)線(xian)圈通(tong)電，通(tong)電后對(dui)壓(ya)板(ban)產生引力(li)，從而(er)實現對(dui)壓(ya)板(ban)和底座之(zhi)間薄板(ban)的(de)夾(jia)持。由(you)于(yu)采用(yong)了電磁力(li)夾(jia)持，使得壓(ya)板(ban)可(ke)以做成多(duo)種工(gong)(gong)件要(yao)求，而(er)且(qie)可(ke)對(dui)有側壁的(de)工(gong)(gong)件進行加工(gong)(gong)。折彎(wan)機可(ke)以通(tong)過(guo)更換(huan)折彎(wan)機模具，從而(er)滿足各種工(gong)(gong)件需求。
