强力旋压工艺是制造柴油机连杆衬套最有效的工艺方法之一,其力学性能受到旋压过程中众多工艺参数的影响。为了改善加工工艺,提高衬套质量,通过正交试验的方法,制备了不同工艺参数下的旋压筒形件。试样拉伸后,得出了应力—应变曲线。根据不同连杆衬套的力学性能需求,调整参数后生产出了合格的连杆衬套。这能为强力旋压工艺提供一定的技术支持和理论保证。
The powerful spinning process is one of the most effective process methods for manufacturing diesel engine connecting rod bushings. Its mechanical properties are influenced by many process parameters during the spinning process. In order to improve the processing technology and improve the quality of the bushing, the spinning cylinder under different process parameters was prepared by orthogonal test. After the sample is drawn, the stress-strain curve is obtained. According to the mechanical performance requirements of different connecting rod bushings, the qualified connecting rod bushings are produced after adjusting the parameters. This can provide some technical support and theoretical assurance for the strong spinning process.
