|
摘要
采用三维建模、合理设计分型面和拔模斜度、优化木模结构等研究,提出了高品质模样有效的解决措施。对660MW汽轮机模样结构进行合理设计、优化参数,减少制作周期,以期提高表面加工质量,提高能源利用率,改善经济性指标。结果表明,在保证模样尺寸、表面质量及坚固耐用的前提下,最大限度降低模样制作成本,提高制作效率。
Based on 3 D modeling, reasonable design of parting surface and draft angle, and optimization of wooden model structure, effective solutions to high quality pattern were proposed. The pattern structure of 660 MW steam turbine was reasonably designed and optimized parameters to reduce the production cycle, so as to improve surface processing quality,improve energy utilization efficiency and improve economic indicators. The results show that under the premise of ensuring the pattern size, surface quality and durability, the production cost of the pattern can be reduced to the maximum extent and the production efficiency can be improved.
