BENDING METHOD AND BENDING DEVICE

摘要

The possibility of performing a bending process again on an area that has already been bent once is reduced. Provided is a bending device including two receiving sections disposed with a distance therebetween; a pressing section that presses a plate-like workpiece, which is supported in a bridged manner between the receiving sections, into a space between the receiving sections; an operable section that applies an external force for causing the pressing section to generate a pressing force; and a marker retaining section that is attached to at least one of the pressing section and the receiving section side and that retains a marker to be adhered to a pressed area of whichever one of surfaces of the workpiece by means of the pressing force.

1. A bending method comprising:
a setting step for setting a plate-like workpiece in a bridged manner between two receiving sections disposed with a distance therebetween; and a pressing step for causing a pressing force to act on a pressing section so as to press the workpiece set between the receiving sections into a space between the receiving sections, wherein the pressing step includes causing a marker to adhere to a pressed area of whichever one of surfaces of the workpiece, the marker indicating that the area has been pressed.
