Latest Patents

One of Ito's latest patents is a bending machine and its operation method. This invention provides a bending machine that allows for a compact angle measuring instrument to be integrated into a mold for precise processing. The operation method is based on learning control, which ensures accurate bending while considering spring back. The machine operates by linearly extending an upper die and a lower die, with the upper die housing the angle measuring instrument. This instrument consists of a corner contacting member with links and an inductive linear position detector that measures the displacement of the corner contacting member. During the bending process, the position and load on the upper die, as well as the bend angle, are measured. After spring back, the bend angle is measured again, allowing for the calculation of a correction value to adjust the bending machine's position for optimal control of the bend angle.

Another significant patent is a driving device for a pressing machine, particularly effective for turret punch presses. This device enables both high-speed processing during low load conditions and high load processing at low speeds, even with a low output motor. The driving device transmits the motor's rotation to the press system through a rotation transmission system that includes a speed reduction gear. A speed change gear is positioned on the input side of the speed reduction gear, allowing for efficient control of the rotation transmission ratio based on the type of process being performed.
