知られている。However, since this structure has a complicated structure, a hemming device having a simpler structure is used as a practical device.
As seen in Japanese Patent No. 176125, a movable die supported by a parallel link mechanism is provided on a side portion of a fixed die, and the movable die is swiveled in a parallel posture toward a workpiece end to pre-bend the workpiece end. It is also known that the main bending is performed.

ことをその目的としている。In the above-mentioned one, since the pre-bending and the main bending can be performed with the same movable die, the structure becomes simpler by that amount, but since the movable die is supported by the parallel link mechanism. However, there is a problem that the movable supporting structure becomes large and complicated by that amount. The present invention has been made in view of the above points, and an object thereof is to provide a hemming device capable of further miniaturizing and simplifying the structure.

The present invention is a hemming device in which a fixed die for setting a work is provided with a movable die that abuts an end of the work and bends the edge of the work, wherein the movable die bends the end of the work. It is characterized in that the movable mold is pivotally supported on the base on which the fixed mold is mounted so as to make a circular motion in the direction.

そして、可動型は枢軸で軸支されるだけであるため、可
動型の支持構造が小型簡素になる。[Operation] The work end is smoothly pre-bent and main-bent in one step by the movable circular motion with the pivot as the fulcrum.
Since the movable type is only pivotally supported, the supporting structure of the movable type becomes small and simple.

The bracket 3 is fixed to the side of the bracket 3 and the movable die 4 for bending the end of the work is pivotally supported on the bracket 3 via the pivot 5 at its lower end.

た。The movable die 4 is formed in an inverted L-shape whose upper portion is bent toward the fixed die 2 side, and a pressurizing portion 4b for contacting the work end Wa is formed at the lower end of the bent portion 4a. did. Further, the movable die 4 is urged to an outward escape position by a spring (not shown), and a ram 6 provided above the fixed die 2 moves up and down to abut on an inclined surface 4c of the upper end of the movable die 4. The rod 7 is vertically installed, and the movable die 4 is rotated inward by the descending of the ram 6 to perform the hemming processing of the work end portion Wa.

に行われる。The details are as shown in FIG. 2. When the movable die 4 is rotated inwardly, the pressurizing portion 4b moves while changing its posture on a circular arc locus around the pivot 5, and then, as shown in FIG. As shown in (a), the pressing portion 4b abuts on the upper edge of the work end Wa, and the work end Wa is preliminarily bent as shown in FIG. The contact point of the pressurizing portion 4b with respect to the end Wa moves to the bending base end side of the work end Wa, and the work end Wa adheres to the inner plate W'as shown in FIG. 2C. Be bent. In this way, the preliminary bending and the main bending of the work end portion Wa are smoothly performed in one step.
