墊片沖孔落料復合膜畢業論-wenkub

　

【正文】 的制造必須依靠模具才能夠生產加工出來。其中以冷沖壓模、塑料模的技術要 求和復雜程度較高。 在這次設計中根據所給題目的要求，首先對沖壓件進行了分析，分析該零件的尺寸精度得出用一般精度的模具即可滿足零件精度的要求，再從零件的形狀、尺寸標注及生產批量等情況看，選擇加工方案。s life more and more close relation. We use the workpiece mold processing, so as to meet the needs of the people, the mold development has brought new life to us, the new era. Due to the characteristics of different materials and processes, production equipment is different, the mold type many, but the most widely used are the following: cold stamping die, plastic mold, fing mold, die casting, powder metallurgy mold, rubber mold, glass mold etc.. The technical requirements of cold stamping die, plastic mold and a higher degree of plexity. Along with the industry to improve the quality of the products, stamping products production is present many varieties, small batch, plex, largescale, precision, renewal speed of change characteristics, stamping mould is efficient, precision, long life, largescale development direction. In order to adapt to market changes, along with the rapid development of puter technology and manufacturing technology, stamping die design and manufacturing technology is by hand design, rely on artificial experience and conventional machining technology to the puter aided design (CAD), puter aided design and manufacturing of CNC machining, CNC machining is the core of the (CAD/CAM) technology transition. In the graduation design using puter aided design (CAD) assembly drawing die main parts and mould, using a numerical control machining, CNC wirecut EDM and other advanced processing technology. In this design according to the requirements of the topic, the stamping parts are analyzed, analysis of size precision of the parts obtained by the general precision of the mould can meet the precision requirements, from the shape, dimensions and mass production situation, the processing scheme selection. According to the prehensive analysis of the parts, mold design I in this design is inverted blanking and punching pound die, mainly introduces the blanking, punching die structure and the design of the blanking die, blanking and piercing principle. Hope to be able to use the specialized knowledge and skills learned, successfully pleted the graduation design.
