Abstract
PURPOSE:To perform the working of door panels with center windows in various sizes from a piece of blank and to improve the material yield by setting the length of a bending die according to the length of the opening part of a center window by a split bending die group. CONSTITUTION:The setting of the number of uses of the split bending die corresponding to the center window length is performed by a setting mechanism. The bending die group used by turning a set bar 11 is set to a bending die line and others are descended. The work sheet 50 blanking a center window part is located at the bending due line. An opening end edge part is clamped with the descend of a ram 1, an L-shaped bending is executed and U-shaped bending is executed with a 2nd bending. The backup member 18 drooped into a hollow opening part is fitted to the step of a lower die block 9 to support the reaction force of an upper beam. After completion of the bending of a 1st side the other side working is executed by turning the panel on the horizontal plane inside. The working of the door panel with center window in various sizes can be done from a sheet of a blank and the processing man/hour of the material yield can thus be reduced.
