傳統製造技術面對精微齒輪產品上，於原有模具設計技術是無法對精微形狀在成形過程中提供抑制材料發生破裂的靜水壓力；當面臨許多3C/IA高科技產品性能不斷被提升，產品的零組件尺寸被導入精密及微形趨勢，利用傳統製造技術生產精微產品是不易辦到。近年來，有一項製造工藝技術發展，即謂一種溝道式下料與擠切成形技術，它能成功地對板材(直徑40mm厚度10mm)及塊材(直徑40mm厚度30mm) 進行成形，且所得到產品品質都能優於傳統技術。技術特點為在模具上設計一道環狀凹槽；於成形的初步階段，溝槽對材料局部集中施加極大靜水壓力保持，並抑制減緩材料提早發生破裂至使成品與餘料脫離。基於上述特點，將技術轉入精微齒輪零件製造成形是具有助益，是一個可行性高的精微成形技術。提案三年期計畫案建立一個新技術知識庫，第一年：模具溝道技術應用於薄板材精微齒輪下料成形之研究。第二年：模具溝道技術應用於厚板材之精微齒輪擠切成形研究。第三年：雙重溝道設計對精微齒輪成形之研究。At present, traditional manufacturing technology cannot carry out a better quality manufacturing process for miniaturized gear by reason of the mould design cannot provide the material with an effective compressive stress. When faced with many 3C/IA high tech product performance is continuously upgraded, the micro machine tool plays an important role in micro manufacturing. In recent years, there is a manufacturing technology development that a trough-form blanking and extrusion cutting technology and can successfully produce high-quality parts in sheet (diameter 40mm thickness 10mm) and block (40mm thickness of the diameter 30mm) material and can be better than the traditional technology. The technical characteristic is to design a ring trough-form on the mould that well provided a hydrostatic pressure to the material to resist the deformation of the tensile stress. Based on the above characteristics, the trough-form is a helpful to transfer technology into the manufacture of miniaturized gear parts, and it is a feasible and high precise forming technology. Proposal three-year plan to establish a new technology knowledge base, the first year: Application of mould trough-form technology to thin plate miniaturized gear blanking forming research. The second year: Mold trough form technology applied to the thick plate of the miniaturized gear extrusion cut-shaped research. The third year: Double trough form design to the study of miniaturized gear forming.
