Process Modeling In Cold Forging Considering The Process‐Tool‐Machine Interactions

摘要: In this paper, a methodic approach is presented for the determination and modeling of axial deflection characteristic whole system stroke‐controlled press tooling system. This realized by combination experiment FE simulation. The uniquely measured in experiment. determined simulation to avoid experimental investigations on various systems. stiffnesses are combined substitute stiffness that integrated into process as spring element. Non‐linear initial effects modeled with constant shift factor. was applied full forward extrusion C‐frame. A comparison between experiments results model showed high accuracy model. represents entire behavior can be used calculation mathematical based variant simulations response surfaces. subsequent optimization step, an adjusted tool design determined, compensates influence deflections workpiece dimensions leading accuracy. Using knowledge behavior, required number reduced.
