碩士 === 國立高雄應用科技大學 === 模具工程系碩士班 === 94 === In this paper a design metholody for the precision stamping products and dies is proposed. The developed method is applied to the stamping die and blank optimal design for the striking face part of a golf wood head. The scanned golf head data have been analyzed to obtain the product geometry of striking face for strking the golf ball. The stamping die with the springback control technology proposed in this paper is designed to produce a precision face part. In this thesis a stamping die design and forming process analysis method for the conversion of reverse engineering to forward engineering has been established. The application of a golf head face part stamping demonstrates the improvement of the better surface curvature control. The proposed Bi-arc (double curvature) swept surface model is capable of cooperating with the design parameters of the horizontal and vertical radii. Two forming processes, blanking after forming, and forming after blanking, are proposed. The former process uses a larger initial blank and product is cut off from the stamped part. The drawbead design is adopted to control the springback of product in the former. While the later process designs an optimal blank profile in advance. The optimal blank is stamped to produce the product directly. The variable double curvature design of stamping die is adopted to control the springback of product in the later process. The energy method is adopted to analyze the forming process and predict the springback. Die face design rules and modification formula have been proposed to control the product springback precisely to meet the precision requirement of contour error within the range of 0.05mm to 0.1mm.
