本文介绍成批生产200、300系列轴承套圈锻件一次加热锻成的工艺及其模具。即内外圈一次切料,外圈穿孔时所得的料芯被挤压成内圈;基本设备为四台曲轴压力机和一台辗扩机。生产实践证明,采用本工艺后技术经济效果很好,与以前采用“三次加热”锻压工艺相比,提高了质量,又使煤耗降低55％以上,材料利用率达45％,生产率显著提高,模具寿命延长。本文介绍了该种工艺过程,205轴承套圈锻压工艺参数的选择、模具设计等。附图7幅
This article describes the mass production of 200,300 series bearing ring forging a heating forging process and its mold. That is, a cut material inside and outside the circle, the outer core perforation obtained when the core is extruded into the inner ring; basic equipment for the four crankshaft presses and a rolling machine. The production practice has proved that the technical and economical effect is very good after using this process. Compared with the former “three times heating” forging process, it improves the quality, reduces the coal consumption by more than 55%, the material utilization rate reaches 45% and the productivity increases remarkably. The mold Longer life expectancy. This article describes the kind of process, 205 bearing ring forging process parameters of choice, mold design. Figure 7 Figure
