微型弯曲模制造

Micro bending mold manufacture

随着微机电系统技术的发展对微型制件需求的不断增长,以传统的微细加工方法成形微小制件难以满足微系统的应用要求,而用微型模具成形微小制件,具有生产效率高、制件质量稳定等优点,成为微成形加工领域的重要工艺发展方向。研究对实验所用的微型弯曲模进行了总体结构设计,得到了模具的装配图和零件图。在分析微细加工方法的技术特点的基础上采用微机械加工法加工模具,并在万能试验机上进行试验,试验表明,所冲制的弯曲件符合要求。

Due to the increasing demand for micro products along with the development of micro electromechnical system technology, fabricating micro products by traditional micro-machining technology can hardly meet the requirement of microsystem. Nevertheless, fabricating micro parts employing micro-molding technology has becoming an important development trend for its high efficiency, steady quality and so on. This research gives general construction design for the micro bending mold, the drawing of mold assembly and parts. Based on the analysis of the machining characters of some kinds of micro-machining method, adopting micro-machining methods, micro mold is fabricated, then tests is carry out on the tensile testing machine, and the results show that bending parts are proper.
