| 摘 要： | 为获得较好的前筒成形效果，对前筒的挤压成形方案及工艺参数进行研究。利用实际生产加工经验和理论对前筒的5种挤压成形方案进行对比分析，得到最优方案; 利用DEFORM-3D软件对最优方案进行实际加工过程的仿真，并以正交试验进行数据处理分析，获得最佳工艺参数。分析结果表明，第5种方案最优，即在压形时，将小端挤出26 mm，在复合挤压时将内孔挤出7 mm深度。仿真结果显示:压形过程中的最佳工艺参数是摩擦因数0.15、成形速度10 mm/s、凹模的硬度63 HRC; 复合挤压过程中的最佳工艺参数是摩擦因数0.08、成形速度10 mm/s、凸模的硬度63 HRC。本研究对前筒的实际生产加工具有一定指导意义，也可为其他前筒类零件的生产加工提供参考。

| Abstract: | In order to obtain a good front tube forming effect, the extrusion forming program and processing parameters of the front tube were studied. Using the actual production and processing experience and theory to compare the five kinds of extrusion forming schemes of the front tube, and the optimal solution was worked out; using DEFORM-3D software to simulate the actual machining process and carrying out data processing by orthogonal experiment analysis, the best process parameters were obtained. The results of the analysis show that the fifth scheme is optimal, namely: when pressing, the small end is extruded by 26 mm and the inner hole is extruded at a depth of 7 mm during compound extrusion. The simulation results show that the optimum process parameters are the friction factor of 0.15, the forming speed of 10 mm/s and the hardness of the die of 63 HRC. The optimum process parameters in the process of compound extrusion are the friction coefficient of 0.08, the forming speed of 10 mm/s, Punch the hardness of 63 HRC. This study has certain guiding significance for the actual production and processing of the front tube, and also provides reference for the production and processing of other front tube parts. |
