基于UG电子零件压线卡冲压工艺与模具设计.doc

PAGE PAGE IV 摘 要 本文介绍的模具实例结构简单实用，使用方便可靠，首先根据工件图算工件的展开尺寸，在根据展开尺寸算该零件的压力中心，材料利用率，画排样图。 根 据零件的几何形状要求和尺寸的分析，采用复合模冲压，这样有利于提高生产效率，模具设计和制造也相对于简单。当所有的参数计算完后，对模具的装 配方案，对主要零件的设计和装配要求技术要求都进行了分析。在设计过程中除 了设计说明书外，还包括模具的装配图，非标准零件的零件图。 本套模具包括落料冲孔复合模和弯曲模两套模具，在模具的结构设计和计算完成后，开始利用UG NX建模模块下设计模具的每个零件图，如上、下模座，上、下垫板，凸、凹模等，在零件的设计过程中需要利用UG NX的拉伸、旋转、扫掠、孔等各种功能，有利于我们熟悉UG NX的强大功能。之后在UG NX装配模块下再将零件装配。最后再利用UG NX将零件的三维图转换为二维图。 关键词：模具 复合模 弯曲模 冲压 UG NX Abstract This text introductive molding tool solid example the structure is in brief practical, the usage convenience is dependable, first according to the work piece the diagram calculate the work piece to launch size, at according to launch the pressure center that the size calculates that spare parts, the material utilization, painting row kind diagram. According to spare parts of several the shape request with the analysis of the size, adoption compound the mold hurtle to press, so be advantageous to an exaltation production an efficiency, molding tool design and manufacturing also opposite in simple. When all parameter calculations are over after, requested the technique requests to the design and assemble of the main spare parts to all carry on analysis to the assemble project that whets to have. During the period of design in addition to designing manual, also include the assemble diagram of the molding tool, the spare parts diagram of the not- standard spare parts, the work piece processes the craft card, the craft rules distance card, the not- standard spare parts processes craft process card. This set of punch dies including blanking die and bending die two sets of composite mold, in mold design and calculation of the structure is complete, start using UG NX Modeling to design the mold for each part drawing, above, under the mold base, the next plate, convex, concave mold, the parts of the design process need to use UG NX stretching, rotating, sweeping, hole and other features will help us know the power of UG NX. Finally, using U
