This paper is aimed to investigate the process design and control method in cold rotary forging of parts with non-rotary upper and lower profiles. Using the analytical and FE simulation methods, three critical technological problems in the cold rotary forging process of this kind of parts are resolved reasonably. The first one is that an accurate design method of the non-rotary upper die is presented based on the geometrical and kinematic relationship between the upper die and upper profile of parts. The second one is that the interference judgment between the upper die and upper profile of parts can be achieved by analytically obtaining the trajectory of any point in the upper die. The third one is that the metal flow and geometrical accuracy of the non-rotary upper profile of parts can be effectively controlled through optimizing the process parameters. On the basis of the above research, the cold rotary forging process of a typical gear part, both the upper and lower profiles of which are non-rotary, is investigated numerically and experimentally. The results indicate that the desirable geometrical accuracy of the non-rotary upper profile of the gear part can be obtained, which verifies that the process design and control method presented in this paper is valid and cold rotary forging can thus be used to manufacture the parts with non-rotary upper and lower profiles. 相似文献

Today the technological design of fine machining processes like finishing of plane surfaces is still a procedure based on experience. In addition, finishing technology is the result of an empirical approach. Innovative methods for designing and controlling finish operations make use of models and the implementation of procedures that allow the derivation of optimal technological parameters and process control strategies as well as the prediction of cutting behaviour of abrasive tools. These process and technology models are based on measuring and evaluating process variables like process forces or cutting torque and parameters of the electric drive like motor current or torque. With these models a finishing process is achieved on the basis of mathematical and technological principles wherein the grinding tool works in a self-sharpening condition providing optimal results. 相似文献

智能工艺设计是智能制造的技术关键和基础。为了提高工艺设计效率,提出一种基于参数化工艺模板的智能工艺设计方法。其基本思路是利用参数化方式将工艺模板中的可变信息通过参数来进行表示,并以参数表达式和融合规则的方式建立工艺信息、工艺参数和零件参数的参数化关系,从而基于参数的驱动实现工艺智能设计。重点阐述参数化工艺模板方法中工艺、参数以及规则的表示,并对基于参数化工艺模板的工艺推理流程进行详细讨论,最后以筒形件的旋压工艺设计为例进行了智能工艺设计的验证,说明该方法易实现、效率高。 相似文献
