The basic principle is to use a series of rules with a high degree of adjustable basic body (Punch), Based on the basic body of the real-time control, to construct the required shape forming face, replace the traditional mold of the plate to achieve rapid 3D-Forming. Specific design ideas : Design, upper and lower lattice model used in the form. Every one of the lattice can be highly regulated through the screw, and each screw is equivalent to a lattice. installation of the screws installed board. Stepper motor through the requirement of screw rotating adjustment screw to adjust the height. Stepper motors MCU or PLC control, and the installation of a ceiling-Switches and sensors. so that the whole control system has become a closed loop controllable. Stepper motor control required for each one after adjusting screw, at this time, been required, under the model. Installed processing needs of the sheet metal blank, under the fixed mold, Press again to the use of model scale downward direction exert enough pressure on the plates of plastic forming the necessary changes shape. The choice of control systems, taking into account the relative PLC MCU it has high reliability, strong anti-jamming ability, Programming is easy and hard infrastructure complete, and easy to use user, system design, installation, commissioning work less, maintenance workload, the maintenance and so on and the use of PLC control systems. Key Words: No pressure forming die Multi-point Forming Motor Control St
