PURPOSE:To reduce the man-hour, and to perform a work safely, by providing a gap between benders of plural split bending benders, so that they can be adjusted to a bender having length conforming with bending length of a steel plate. CONSTITUTION:This device bend-works a steel plate by using split benders A, B and C as they are, or providing a gap between the benders and using a bender set to desired bending dimensions. Said benders A, B and C are constituted so that they can be attached and detached to and from a ram 2, and length of the bender is adjusted by a gap (g) between the benders.
