摘要
叉形排气管结构复杂,使用传统的方法难以设计出产品和模具。应用CAD/CAM技术针对叉形排气管零件进行熔模铸造模具设计,并且针对复杂型腔进行数控加工仿真。叉形排气管表面空间点云数据由三坐标测量机测量,然后通过逆向工程软件Imageware进行曲面和实体模型的创建,精密铸造模具用Pro/E软件完成整体设计,用Mastercam软件模拟复杂模具型腔的加工路径,最后用CIMCO软件仿真加工。该技术的应用缩短了发动机1/4~2/5的开发周期,降低了开发成本15%~35%,提高了汽车零部件的开发效率和品质。
It is difficult to design products and molds of fork exhaust pipes using traditional methods due to its Complex structure. The casting mould for exhaust pipe fork parts was designed using CAD/CAM technology, and NC machining process for complex cavity was simulated. The surface point cloud data of the fork exhaust pipe were measured by three coordinate measuring machine, then the surface and solid model were created by reverse engineering software Irnageware, using Pro/E software to complete the overall design of precision casting mould, using Mastercam software to simulate the processing complex mold cavity size, and using the CIMCO software to simulate processing. The application of this technology can shorten the development cycle of engine, and reduce the development cost.
