Disclosed is a steel plate bending apparatus which bends a steel plate, which is a base material for a frame of an electric appliance, while transferring the steel plate such that a next process for manufacturing the frame of the electric appliance is followed. According to an embodiment of the present invention, the steel bending apparatus comprises: a main body part; a first main forming roll and a second main forming roll mounted on the main body part along a movement path of the steel plate, rotating around a first rotation axis to bend the steel plate; a first side forming roll and a second side forming roll which respectively rotate around a second rotation axis and a third rotation axis with the steel plate having passed the first main forming roll therebetween; a side forming roll disposed between the first main forming roll and the second main forming roll in order to additionally bend a part bent by the first main forming roll, allowing the second main forming roll bend the additionally bent part; and a position changing part connected to the first side forming roll to change a position of the first side forming roll such that a gap between the first side forming roll and the second side forming roll is adjusted to correspond to a thickness of the steel plate. |
