Development of the tube bender of based on PCI-1240

PCI-1240 is a 4-axis motion control card based on PCI bus. It is suitable for tube bender controlling system. To solve the problems of complexity in controlling and complicated operation in the conventional tube bender, a new multi-motor based on PCI-1240 is developed. With the establishment of the instruction code, a multi-motor driving mechanism and the controlling of reading bending data are applied in the new tube bender, which employs three servo motors. With the three mechanisms controlling, the machine structure is simplified. The tube quality is improved. The productivity is promoted. And mechanical-electrical integration level of the tube bender is enhanced.
