基于Pro/E的连杆锻模CAD系统开发

在完成R175A型柴油发动机连杆冷热锻件工艺CAD的基础上,以Pro/E软件为平台,运用特征造型技术,改变了传统锻模设计、加工都是依据锻件图和毛坯图来进行的设计路线,由二维零件图直接建立锻件三维模型,实现了连杆锻模计算机辅助设计,从而提高了锻模设计效率和精度,缩短了锻模开发周期,克服了传统的锻模设计缺点

Development of CAD System for the Forging Dies for the Connecting Rods Based on Pro/E

Based on the CAD of the technological process for the cold and hot forgings of R175A diesel engine connecting rod,with the Pro/E3D solid modeling software as a platform,by using the feature modeling technology,the3D model of a forging has been directly built from a2D part drawing.The traditional technical route that the design and manufacture of forging dies were done according to the drawings of the forgings and blanks has been changed,and computer-aided design of the forging dies for connecting rods has been realized.Thus the efficiency and precision for designing the forging dies have increased,the development cycles of the forging dies have been shortened,and the traditional design shortcomings overcome.
