折(zhe)彎(wan)機(ji)是一(yi)種能(neng)夠對(dui)薄板(ban)進行(xing)折(zhe)彎(wan)的(de)機(ji)器，其(qi)結構(gou)主要包括支(zhi)架(jia)、工(gong)(gong)作(zuo)臺(tai)和夾(jia)緊(jin)(jin)板(ban)，工(gong)(gong)作(zuo)臺(tai)置(zhi)于(yu)支(zhi)架(jia)上(shang)(shang)，工(gong)(gong)作(zuo)臺(tai)由底(di)(di)座(zuo)和壓板(ban)構(gou)成，底(di)(di)座(zuo)通(tong)(tong)過鉸鏈(lian)與夾(jia)緊(jin)(jin)板(ban)相連，底(di)(di)座(zuo)由座(zuo)殼、線圈(quan)和蓋板(ban)組成，線圈(quan)置(zhi)于(yu)座(zuo)殼的(de)凹陷(xian)(xian)內，凹陷(xian)(xian)頂部覆(fu)有(you)蓋板(ban)。使用時由導線對(dui)線圈(quan)通(tong)(tong)電，通(tong)(tong)電后(hou)對(dui)壓板(ban)產生引力，從而(er)實現對(dui)壓板(ban)和底(di)(di)座(zuo)之間(jian)薄板(ban)的(de)夾(jia)持(chi)。由于(yu)采用了電磁力夾(jia)持(chi)，使得壓板(ban)可(ke)以做成多種工(gong)(gong)件(jian)(jian)要求，而(er)且可(ke)對(dui)有(you)側(ce)壁的(de)工(gong)(gong)件(jian)(jian)進行(xing)加工(gong)(gong)，操(cao)作(zuo)上(shang)(shang)也(ye)十分簡便。

折彎(wan)機使用時由導線對線圈通電(dian)，通電(dian)后對壓(ya)(ya)板(ban)(ban)產生(sheng)引力，從而(er)實現對壓(ya)(ya)板(ban)(ban)和底座之間薄(bo)板(ban)(ban)的夾持(chi)。由于采用了電(dian)磁力夾持(chi)，使得壓(ya)(ya)板(ban)(ban)可以做成多種工件(jian)要(yao)求(qiu)，而(er)且可對有側(ce)壁的工件(jian)進行加工。折彎(wan)機可以通過更換折彎(wan)機模具，從而(er)滿足各種工件(jian)需求(qiu)。
