Simulation Of Ring-shaped's Forging By UBET And Optimization Of First-stage Blank Dimensions

With modern science and technology developing ,subjunctive manufacture depended on computer numerical simulation technique is more and more used in production and practice. Especially in plastic yielding fields, it is a powerful tool in improving forming quality ,technology and optimizing die design. This paper is a active attempt to the technology in die-forging.In this paper ,with upper bound elemental technique ,many kinds of ring-shaped blank forming is simulated. At fist ,the kinds of ring-shaped are summarized. Secondly ,on the basis of clarifying basic of UBET and deducing basic equations ,the forming through process of ring-shaped blank is simulated and the first-stage blank dimensions are optimized. Taking two kinds of ring-shaped blank as example ,the simulation technique and process is introduced in detail and some regulation result about the forming of ring-shaped blank is gained. Hence ,it is a useful explore in plastic yielding fields.On the basis of theory study ,according to Lead and high-temperature Steel similar principle in quality ,first-stage blank dimensions optimized by simulation is experimented to verify its reasonable. The result of experiment and the result of simulation are mostly accordance ,which show fully forming process and simulation result are correct.In the paper ,Delphi5.0 ,with powerful functions and visual programming language ,is used to exploit friendly interface ,which make the system convenient to customer's use. It also makes the system easier to be enhanced and be updated ,simply to be handled and convenient to use.Finally ,the regulation conclusions of study are given.
