CUTTING BLADE BENDING DEVICE

摘要

A cutting blade bending device is provided to generate pressure rotary force at upper and lower parts of one bending pin and to transfer differential pressure of the bending pin to a cutting blade so as to make the cutting blade with an accurate shape. A cutting blade bending device comprises a bent holder(170), upper and lower rotary bodies(130,330), a bending pin(190), and rotary body driving controllers. The bent holder has passages(171) and is projected from a front end thereof. The upper and lower rotary bodies are placed at upper and lower sides of the bent holder. The bending pin bends a cutting blade by the upper and lower rotary bodies. The rotary body driving controllers control the drive of the upper and lower rotary bodies. The rotary body driving controllers have an upper servo motor(110), and a lower servo motor(310).
