| Roll forming machine is the mid-eighties the advent of the new energy-saving equipment, which is a machine, hydraulic, electrical automation as one of the devices, and more used in sheet metal forming. From the current domestic situation, various molding materials, the increasing demand for large-scale size, the device also to large-scale energy-saving, environmentally friendly development. Variety of forming large-scale production line has entered the construction phase, so the large demand for roll forming machines are becoming increasingly rising. Roller press specific small size, light weight, the advantages of high energy utilization, the system the use of a roll forming machine, in the same case production, energy consumption, material consumption will be reduced. In very large domestic and international market demand, therefore,Market prospect is very broad.The paper the7.5KW color plate roller forming machine automatic control system design. Through access to information, understanding and Overseas roll forming machine, roll forming machines are familiar with process, a clear design concept, hardware design, PLC as the main roll forming machine control equipment, the preparation process in order to achieve system-wide automatically. Main topic of color plates to complete7.5KW automatic roll forming machine control hardware design, system design and electrical transmission system to perform the selection of components, high power electrical mapping, programmable logic controller with PLC control system design,PLC completed the selection, establishment of port assignments and procedures。... |
