摘要:

 以491Q连杆体为研究对象,根据连杆体结构特点和技术要求,设计了该连杆体毛坯的锻造工艺流程,详细介绍了锻造模具设计与制造工艺,包括通过实验确定锻件收缩率、完成热锻件图设计、模具结构设计以及加工工艺流程。选用UGNX、CAD/CAM工具软件对模具进行了三维建模,并做数控加工编程,生成刀具轨迹,经过后处理得到数控加工程序。实验证明,该连杆体锻模在生产中使用正常,产品合格率高,完全满足了企业的生产需求。

 According to the body structure features and technical requirements of 491Q connecting rod used for the studied object, the forging process of connecting rod blank was designed. The forging die design and manufacturing process, including the forging reduction determined by the experiments, accomplishment of hot forging drawings,die structure design and machining process,were introduced. The 3D model of die was established by UGNX and CAD/CAM, the numerical control machining program was written, the tool path was generated and the machining program was obtained after post-processing. The results show that the forging dies of connecting rod are normally used in the producing, by using which the qualified rate of product is high,and the producing requirements of enterprise are met.
