Description

[Brief explanation of the drawing]

Figures 1 to 4 show an embodiment of the present invention, with Figure 1 being a vertical sectional side view of the main parts, Figure 2 being a front view showing the overall configuration of the bending device, and Figure 3 being a bending device. Fig. 1 is a diagram corresponding to the processing state, Fig. 4 is a vertical cross-sectional side view of the main part when the bending radius is changed, and Fig. 5 is a diagram equivalent to Fig.
The figure is a diagram corresponding to FIG. 1 showing an example of a conventional bending device. In the figure, 11 is the main body frame, 12 is a rotating blade plate (mounting member), 16 is a lifting plate, 18 is a fixed type, 19 is a rotating type, 20 is a horizontal frame plate (mounting member), 21 and 32 are bending types, 22 and 31 are plate members, 25 and 26 are indexing devices, 27 is a disk (movable member), and 28 to 30 are support pins (positioning members).

Claims (1)

[Scope of utility model registration request] A plate material placed between a fixed die and a rotating die is pressed and fixed to the fixed die by a bending die, and the rotating die is rotated about a single axis, so that the plate material is moved along the curved surface of the bending die. The bending die is replaceably provided, and on the other hand,
The fixed type and the rotating type are provided on each mounting member so as to be movable in the height direction, and each of these mounting members is provided with a movable member having a plurality of positioning portions having different heights. 1. A bending device for plate material, characterized in that one positioning part is selected from a plurality of positioning parts, and the fixed mold and the rotating mold are respectively fixed to the selected positioning part.
