碩士 === 國立高雄第一科技大學 === 機械與自動化工程系碩士班 === 106 === This study is to research the slider conducted which is generally made by foundry. Because of the common foundry easily causes the defects like voids and fissure. So in this experiment, hot forging process is used for the material refinement, homogenization and better fatigue resistance, toughness, etc. The material in this study is the general round bars and the hierarchy round bars to compare the compatibility and the formability of each other in different processes. Before the particle development, use the Deform-3D for simulation for data like the forging loads or stress of die set to evaluate the possibility of the whole process. As result, in temperature 1050℃,the forming load of the general round bars falls in between 330 tons to 370 tons which is close to the outcome of simulation 339 tons, but the mold cavity haven’t been completely filled up. On the other hand the hierarchy round bars at the same temperature not only the forming load which is around 340 tons to 380 tons matches the modeling data 360 tons but also expressing better formability, which means the hierarchy round bars are more suitable for the slider manufacturing. After the mold trail, the major dimensions of object are in compliance with the requirements and it’s stable. Forming die stripping will be improved and mass production. According to the forming and the stability of dimensions, this mold design works efficiently with great precision. Keywords : Slider, Hot forging
