On CAPP System Of Ring Rolling Technology

Ring rolling is a high-efficiency and high-quality advanced manufacturing technology. It is a plastic forming technology, in virtue of ring rolling machine, in which the diameter of the ring increases as the ring cross-section decreases. It has many characteristics such as saving forming force and production cost, increasing utilization ratio of energy and material, rising productivity, widening processing range of ring products etc. As a result, ring rolling has become the main manufacturing method of many kinds of superior seamless ring parts.Forming ring rolling processing technique comes down to many problems, including limiting conditions, calculating process parameters and checking up. At home, the traditional method of establishing the forming ring rolling processing technique that the bulk of the people are using has much unavoidable defect, such as low efficiency, high cost in processing technique design and low precision and so on;in foreign countries, the Computer-Aided Process Planning System only aimed at the given machine. For solving these problems, on the basis of forming ring rolling processing technique theory, use the method of CAPP and CAD technique to exploit the CAPP_RR1.0 system.The CAPP_RR1.0 system set up in Generative CAPP. It includes process design of ring with rectangle cross-section, inner side step cross-section, outer side step cross-section and taper cross-section. The system's Interface is consistent with Windows' style and put the process of judgment, selection and checkout into the program of system directly. The manipulation is easy. Imports the correlation parameters in the input interface of each main module, then can get the result immediately. In addition, design the exclusive icon to make the interface wonderful and the style unified, which meet the special function of the system.CAPP_RR1.0 system contains over 30 common kinds of domestic and overseas machines, and technical parameters are compiled in the system as conditions. It assures the practicability of the system. It also establishes a database of cold ring rolling and hot ring rolling materials, and realizes a function of appending material performance and extends a database of material performance for its convenience, andimproves the practicability of the system. Process design of the system mainly contains forging parts design, roughcast design, mold design, process parameter design and the choice of machine. CAPP_RR1.0 system integrates the technology of CAD, and it can transfer the CAD graphs of forging, roughcast and mold that are automatically drawn.CAPP_RR1.0 system is compressed Setup.exe file and easy to be installed. Its volume is so small that it can be transferred and installed easily. Comparing with traditional process, it doesn't have strict requirement of designer, and it is easily designed. It assures the veracity and rationality of calculation, and improves the efficiency and quality. As a result, it reduces the cost and period of design that suits the developing trend of industry design.
