Development of Precision Forging Process and Mold Design for High Value-Added Gear-Type Cable Clamp( I )

Founded in 1978, Hanlong Industrial Co., Ltd. is both a manufacturer and seller of hand tools, allcertified by ISO9001:2008 Quality Assurance Standard. The main products include telecommunication andnetworking crimping tools, precision cutters, cable strippers, terminal crimping tools, punch down tools,cable tie fastening tools, tool kits, fiber optic SMA/SMB tools, coaxial cable cutter & strippers, etc..However,Hanlong Industrial Co.,Ltd has faced a very severe challenges, mainly from mainland China, for mimicking the design & products at all costs. Therefore, desperate in need of help from the research and developmentusing the latest technology is the top priority.In this study, a precision forging process for making cable strippers with highly precise gear shapes is numerically and experimentally investigated. The aim of the study is to design the crucial mold of the finishing forging process with highly precise gear shape such that the mold rationalization can be achieved (tool wear is prolonged and tool fracture should be minimized). In addition, in order to ensure the appropriateness of the suggested modification, a 3-dimensional finite element simulation on each sequence is performed, and carefully compared with experimental investigations.Year 1:A novel process based on lost wax perform and near net shape forging mold will be developednumerically and experimentally.Year2:In order to further reduce the material cost with enhanced mechanical properties, a multiple shapesmold will be developed to significantly increase the productivity.
