折(zhe)彎(wan)機是(shi)一(yi)種能夠對(dui)薄板(ban)(ban)(ban)(ban)進(jin)行折(zhe)彎(wan)的機器，其結構主要包括支架、工作(zuo)臺和夾(jia)(jia)(jia)緊板(ban)(ban)(ban)(ban)，工作(zuo)臺置(zhi)于(yu)支架上(shang)，工作(zuo)臺由(you)底座和壓(ya)(ya)板(ban)(ban)(ban)(ban)構成(cheng)，底座通(tong)過鉸鏈(lian)與夾(jia)(jia)(jia)緊板(ban)(ban)(ban)(ban)相連，底座由(you)座殼(ke)、線(xian)圈和蓋板(ban)(ban)(ban)(ban)組(zu)成(cheng)，線(xian)圈置(zhi)于(yu)座殼(ke)的凹陷(xian)內，凹陷(xian)頂部(bu)覆有(you)蓋板(ban)(ban)(ban)(ban)。使(shi)用(yong)時由(you)導線(xian)對(dui)線(xian)圈通(tong)電，通(tong)電后對(dui)壓(ya)(ya)板(ban)(ban)(ban)(ban)產生(sheng)引力(li)，從而實(shi)現對(dui)壓(ya)(ya)板(ban)(ban)(ban)(ban)和底座之間薄板(ban)(ban)(ban)(ban)的夾(jia)(jia)(jia)持。由(you)于(yu)采用(yong)了電磁力(li)夾(jia)(jia)(jia)持，使(shi)得壓(ya)(ya)板(ban)(ban)(ban)(ban)可(ke)(ke)以做成(cheng)多(duo)種工件(jian)要求(qiu)，而且(qie)可(ke)(ke)對(dui)有(you)側(ce)壁的工件(jian)進(jin)行加工，操作(zuo)上(shang)也十分簡便。

折彎(wan)機(ji)使用時(shi)由導線對線圈通(tong)電，通(tong)電后對壓板(ban)(ban)產生(sheng)引力，從而實現對壓板(ban)(ban)和底座之(zhi)間薄(bo)板(ban)(ban)的夾持(chi)。由于采用了電磁(ci)力夾持(chi)，使得(de)壓板(ban)(ban)可(ke)以做成多種工件(jian)要求，而且可(ke)對有側壁的工件(jian)進(jin)行加工。折彎(wan)機(ji)可(ke)以通(tong)過更換折彎(wan)機(ji)模(mo)具，從而滿足(zu)各種工件(jian)需求。
