| 中文摘要: |
| 以花键挤压成形过程为研究对象，利用DEFORM-3D软件对花键的冷挤压成形过程进行模拟；以金属流动、变形程度、成形载荷和模具磨损等作为花键成形过程中的衡量指标，分别设定15°、20°、22.5°、25°和30°的不同凹模入口半角，模拟分析对花键冷挤压成形过程的影响。模拟结果表明，凹模入口半角为20°时，花键的整体成形质量最好。 |
| 英文摘要: |
| Taking the spline extrusion forming process as the research object, the cold extrusion forming process of spline was simulated by DEFORM-3D software. The metal flow, deformation degree, forming load and die wear were taken as the measurement indexes in the spline forming process, and the different die entrance half angles of 15 degree, 20 degree, 22. 5 degree, 25 degree and 30 degree were set respectively to simulate and analyze the influence on the spline cold extrusion forming process. The simulation results show that the overall forming quality of spline is the best when the half-angle of the die entrance is 20 degrees. |
