【摘要】 本课题来源于轴套成型行业的技术革新要求，目的是为了解决无油自润滑轴套的产品质量和生产效率问题。 本课题主要分为两个部分。第一部分：首先，仔细分析了当前轴套加工行业的实际加工工艺和加工水平，找出影响产品质量的因素。接着，在系统研究了传统的冷冲压加工工艺中的弯曲加工理论（轴套成型属于此类方法）的基础上，广泛查阅了国内外有关弯曲加工的最新技术情报资料，吸收了一些对轴套成型有价值的思想和方法。最后，提出具体的改进方案，制定改进后的轴套成型工艺，并设计出模具图纸。第二部分：利用ActiveX Automation技术，通过VBA对AutoCAD 2000进行二次开发来实现模具CAD软件的编制。用户只需输入原始参数（轴套内外径和宽度），即可输出模具图纸和设计结果。更多还原

【Abstract】 The thesis derives from the challenge of technique reforming happening to self-lubrication bearing forming industry and the research aims to enhance the quality and productivity of self-lubrication bearing products.The thesis can be mainly divided into two parts. In the first part, the thesis has firstly anatomized the practical craft and level of the current process of self-lubrication bearing forming industry, and has founded out the key factors accounting for product quality. Then, the thesis has widely referred to the newest domestic and abroad technique information data about bending forming, and has absorbed some ideas and means which are useful to self-lubrication bearing forming, while having systematically studied the theory of bending forming process, which is one of the punch forming process. Finally, the thesis brought forward a concrete better scheme by enacting a reformed forming process and drafting drawings of forming dies. In the Mother part, the thesis has realized the CAD system design by means of application development of AutoCAD 2000 by VBA, making use of ActiveX Automation technique.更多还原
