The utility model discloses a bending device for tubular electric heating element production. Workbench, supporting columns are arranged at the two ends of the bottom of the workbench. A first fixingcolumn and a clamping plate are arranged at the two ends of the top of the workbench correspondingly. A first channel is formed in the lower portion of the first fixing column in a penetrating mode. Amotor II is mounted in the middle of the inner wall of the channel I; the output end of the motor II is connected with a rotating arm; a limiting rod is inserted into the other end of the rotating arm; the outer sides of the limiting rods are sleeved with concentric-square-shaped plates matched with the limiting rods. A push rod is arranged at the bottom of the side, corresponding to the clampingplate, of the concentric-square-shaped plate. A push plate is arranged at the end, away from the concentric-square-shaped plate, of the push rod, a second hollowed-out channel is formed in the lowerportion in the clamping plat
