Abstract
CNC pipe bending machine is an important modern curved plastic processing equipment, which is based on the vector theory, using computer control, to complete any space for three-dimensional tube to meet users requirements. In this paper, it mainly about the research and development of hardware systems on the numerical control equipment for pipe bending machine embedded control system, using embedded microprocessor hardware platform, instead of the traditional general-purpose computers and industrial machines, to control the machining process effectively. On this basis, installation of motion control card PCI-1240U, realized through the motion control card servo motor drive control, to control each axis servo motor drive for accurate operation of rotating gears. In this paper, it mainly about the control system of the embedded hardware systems’ research and development, for industrial control circuit of the basic requirements, using PROTEL software to draw four motor control circuit schematic diagrams and field distribution of the overall structure of the circuit design; according to the design precision and comparison of the cost on components, select the equipment including embedded systems, motion control cards, servo motor, servo motor drive, input and output cards, encoders , sensors and various types of hardware components. This embedded control system designed to control the pipe bending machine for industrial on-site practical operation, mainly about feeding, rotating, bending and other functions of the control. The circuit design and selection of hardware debugging in the industrial field can achieve the desired results.
