液壓折(zhe)彎(wan)機(ji)包括支架(jia)(jia)、工(gong)作臺和夾緊板(ban)(ban)(ban)，工(gong)作臺置于(yu)(yu)支架(jia)(jia)上，工(gong)作臺由(you)底(di)座和壓板(ban)(ban)(ban)構成(cheng)，底(di)座通過鉸鏈與夾緊板(ban)(ban)(ban)相連，底(di)座由(you)座殼、線圈(quan)和蓋板(ban)(ban)(ban)組成(cheng)，線圈(quan)置于(yu)(yu)座殼的凹陷內，凹陷頂(ding)部覆有(you)蓋板(ban)(ban)(ban)。

使用時由導線對線圈通(tong)電(dian)(dian)，通(tong)電(dian)(dian)后對壓(ya)板(ban)產(chan)生引力，從而實(shi)現對壓(ya)板(ban)和(he)底座之間薄(bo)板(ban)的(de)夾(jia)(jia)持(chi)。由于采用了電(dian)(dian)磁(ci)力夾(jia)(jia)持(chi)，使得壓(ya)板(ban)可(ke)以做成多種工件要(yao)求，而且(qie)可(ke)對有側壁的(de)工件進行加工。
