The present invention relates to a device for bending comprising: a subject supplier which supports a plurality of bending subjects, transporting the subjects by aligning the bending subjects in a line towards a direction of movement; a bending part which supports a bending portion of the bending subject; a plurality of supporters which supports the bending subjects on an inlet side and an outlet side of the bending part; and a bending pressurizing part which bends the bending subjects by pressurizing the bending subjects on a side in a direction of movement of the bending subjects. The bending part may comprise a pressurizing head which pressurizes the bending subjects on an upper part. According to the present invention, productivity can be improved as the plurality of bending subjects can simultaneously be fixated and bent. Additionally, product quality can be improved since an inner thickness and an outer thickness of the bending portion can uniformly be adjusted while simultaneously bending the plurality of bending subjects.
