  • Bending machine
    Patent number: 10328476
    Abstract: A bending machine has a main spindle which supports a die. There are two counter dies each mounted on a working arm which rotate about the main spindle. The working arms are driven by link arms which are acted on by a translational drive. There is versatile three-point bending caused by three die points, two on the working arms and one on the die support shaft. The working arm drive includes a translational component which extends through the die support shaft, and which is connected to the link arms. This achieves excellent symmetry and compactness.
