以一种翼状零件为研究对象,在零件结构及工艺性分析基础上,对其进行了冷挤压工艺设计及工艺试验。结合数值模拟和初步工艺试验结果,对预制坯工序与冷挤压模具进行了优化,优化后的挤压力比优化前降低了47%。凹模寿命由优化前的4000件提高到优化后的10000件以上,而且成形件质量良好,生产效率高,极大地降低了生产成本。
Taking a wing-shaped part as the research object, cold extrusion process design and process test were carried out on the basis of part structure and process analysis. According to the results of numerical simulation and preliminary process, the preform process and cold extrusion die are optimized. The optimized extrusion pressure is reduced by 47% compared with that before optimization. The die life is improved from 4000 before optimization to more than 10000 after optimization, and the quality of the formed parts is good, the production efficiency is high, and the production cost is greatly reduced.
