汽车发动机连杆锻模的高速加工

High-speed Machining of Automobile Engine Connecting Rod Forging Die

为了克服汽车发动机连杆锻模在传统加工中表面质量差和生产力低下的缺点,文章提出了基于UG NX 6.0软件的系统平台,采用高速加工技术制造汽车发动机连杆锻模,提出了利用UG建立连杆的3D造型,UGCAM模拟高速加工时刀具的加工路线和锻模的加工过程,生成G代码,最后导入VNUC4.0软件中模拟加工的过程来优化连杆锻模的高速铣削参数。结果表明,采用高速加工技术制造连杆锻模能缩短加工时间,提高锻模精度,对实际生产有较好的参考价值。

In order to overcome poor quality and low productivity shortcomings of automobile engine connecting rod forging die surface in the traditional processing, in this paper, proposes platform based on UG NX 6.0 software, produces automobile engine connecting rod forging dies with high-speed machining technology, it proposes that establishing link 3D model with UG, simulating tool routes when machining highspeed machining and forging dies process with UGCAM, G-code is generated, finally, importing simulation machining process of VNUC4.0 software, optimizes high-speed milling parameters of connecting rod forging die. The results show that producing rod forging die with high-speed machining technology can shorten pro- cessing time, improve the precision of forging die and has a good reference value for actual production.
