| Multi-indenter stamping based on the plate surface deformation characteristics, the optimal deformation path in accordance with the specified sheet forming. This technique with the use of flexible, a wide range of applications. Therefore, in the techniques of three-dimensional surface shape of the plate, stamping technology is an ideal choice. Stamping on each indenter point height adjustment device is the entire system must first solve the problem, it is directly related to the Development of the success or failure of the stamping equipment, metal forming the actual promotion of the device plays a very important role.Controller Area Network (Controller Area Network CAN) is a dedicated serial bus developed for the automotive industry, it is a real-time and reliability of high fieldbus, can effectively support the distributed control system. Make it very suitable for use in the field of industrial control.This paper first introduces the status quo of current research and development of domestic and international multi-head stamping technology and its control system. Forming the embedded control system based on CAN bus stamping on the basis of the principles and methods of analysis of CAN bus communication, design, given the structure of the overall work of the stamping of embedded control systems using the VC design control pressure point movements PC software, to achieve a high degree of automatic control of pressure point. The next bit machine using custom protocol control information obtained from the host computer via the CAN bus to communicate with the host computer, and then by controlling the stepper motor drive to achieve a high degree of target to control the pressure point. Key consideration in the design and embedded control systems used in harsh environments due to stamping the job stability of the system.Finally, the various modules of the control system test results show that the design of embedded control system based on CAN bus stamping forming. |
