あった。Therefore, a plurality of bending dies are set in advance in a stacked state in the direction of their rotational axes, and these bending dies are sequentially driven and replaced in positions corresponding to the tightening dies, chuck device, and core metal device. At the same time, due to the position change of the bending dies, positional deviations in the direction of relative distance movement between the rotating opening die and the clamping die between the driving bending device side, the chuck device, and the core metal device side are to be checked. By having a configuration that allows correction by changing the drive position, it is possible to efficiently produce products with multiple bending processes with different curvatures and radii using continuous operation of one machine without requiring human labor to change bending dies. However, in this type of conventional device, two-dimensional driving movement such as changing the position of the bending die and correcting the positional deviation associated therewith is performed by changing the position of each of the chuck device and the core metal device with respect to the driving bending device. Because the system was designed to be controlled by changing means, it required a large number of drive devices such as cylinders, making the overall structure extremely complex and large.In addition, the control mechanism was complicated and economically disadvantageous when fully automated. there were.

とができる。That is, as mentioned above, for one bar to be bent, the curvature,
A rotary convex type drive bending device for one core device and one chuck device is used to automatically and efficiently process multiple bending parts with different radii without requiring manual labor to change bending molds, etc. is constructed by stacking and fixing a plurality of intermediate molds with different radii of curvature in a concentric manner, as well as the necessary two-dimensional drive movement means J, and devices located close to each other such as the drive bending device and the pressure device. A relatively small and lightweight frame that is equipped with the above-mentioned core metal device and chuck device that are located at a distance from each other can easily become very large and heavy. By employing the changing means, not only two drive mechanisms such as cylinders are required, but each drive mechanism can also be small and have a small capacity.

Moreover, it has now been possible to construct the structure economically.
