| 中文摘要: |
| 针对半轴圆锥直齿轮冷锻载荷大、模具寿命低、齿腔难充填等技术难题，采用分流法的封闭式锻造工艺冷锻半轴圆锥齿轮。研究了型腔充填规律、载荷曲线特点等，并分析了模具运行方式、冲孔连皮位置、坯料尺寸对成形结果的影响。结果表明：分流法能大幅度地降低成形载荷；闭塞式锻造工艺对成形结果没有改善；冲孔连皮的位置及坯料直径对成形结果影响较大。 |
| 英文摘要: |
| Aiming at resolving the technical problems of cold forming process of axle half bevel gear such as excessive forming force, short life of die and insufficient corner filling, cold-close forging based on divided folw method was adopted. Rule of cavity filling, feature of curve of displacement-forging loads were studied. Factors which affect forming result such as the way of die's moving, the sketch of web position, the diameter of blank, were analysed. The results shows that divided flow method is in favor of decreasing the forming force significantly. Process with separable cavity die has no active effect. While the sketch of web position and the diameter of blank can affect forming results seriously. |
