The invention discloses a batch cutting device for twisted steel production, which comprises a base body, the appearance of the base body is of a cuboid platy structure, the surface of the base body is provided with chamfers, and the base body is provided with a convenient-to-move mechanism; and the first motor is arranged on the left side of the upper end of the base body, the first motor is provided with a waterproof structure, and the first motor is provided with an automatic feeding mechanism. The batch cutting-off device for twisted steel production is provided with the scrap iron collecting mechanism, scrap iron generated during steel bar cutting can be uniformly recycled, pollution and waste caused by scrap iron scattering are avoided, environment protection is facilitated, resource recycling is achieved, meanwhile, the correcting mechanism is arranged, bending correction can be conducted on steel bars before cutting, and the quality of the steel bars is improved. The steel bar bending correcting device can correct bending degrees of steel bars in the horizontal direction and the vertical direction, the machined steel bars can be straight, the attractiveness of the steel bars is further improved, the machining quality of the steel bars is guaranteed, and practicability is improved.
