ことができる。As an example of a bendable material, a core material (not shown) made up of a number of connected pieces having an insertion portion approximately equal to the opening width of the opening 1a is inserted into a long material 1 having an opening 1a. The stretch member 2 is fixed to the substrate B, holds the elongated material, and stretches the elongated material by moving the elongated material. A main gear 4 is fixed to the arm receiving board 3, and a fixed mold 5 is attached concentrically. The fixed mold 5 is provided with a guide groove 5a for the elongated material 1. An arm 6 is attached so that it can rotate around a main gear 4. An intermediate gear 7 meshing with the main gear 4 is rotatably attached to the arm 6. A rotary type 9 with a fixed driven gear 8 that meshes with the intermediate gear 7
is rotatably attached to the arm 6, and the rotary mold 9 is provided with a guide groove 9a for the elongated material 1 and a mounting portion 9b for fixing the elongated material 1. The arm 6 may be provided with a rotating portion 10 such as a piston actuator so that it can rotate about the main gear 4, or the arm 6 may be operated by applying rotational drive to the gear shaft of the intermediate gear 7 or the driven gear 8 with a hydraulic motor or the like. In the grooved long material bending device, one end of the long material into which the core material has been inserted is fixedly guided in the guide groove 9a of the rotary mold 9, guided into the guide groove 5a of the fixed mold 5, and then stretched into the stretch member 2. Stretching is applied as you move. The movement of the long material 1 is carried out by the rotating part 1.
0 rotates the arm 6 and rotates the main gear 4, intermediate teeth,
This is performed by rotating the rotary die 9 by a gear train of a wheel 7 and a driven gear 8. By this movement, the elongated material 1 is bent around the rotary die 9 and guided around the stationary die 5 to be bent. When the arm 6 is rotated to a predetermined position and the bending process is completed, the holding of the stretch member 2 is released and the attachment part 9a of the rotary mold 9 is released. can be removed. As detailed above, according to the present invention, it is possible to complete the bending process having the curvature radius centers located on both sides of the long material in one operation, and the bending process can be completed in one operation. Since the bending process is performed in a stretched state, it is possible to prevent deformation and wrinkles and perform the bending process in a good manner.
