| 摘 要： | 采用粉末冶金法批量生产用于制冷压缩机的铁基阀板,研究其在不同装炉方式下烧结、整形工序中平面度的变化情况。结果表明:阀板最佳摆放顺序为凹槽相对并彼此错开,其平面度分别为,烧结后0.14mm,整形后0.07mm;最佳摆放位置为中间放置,最佳装炉量为单排装炉,其平面度均为,烧结后0.23mm,整形后0.06mm;最佳装炉方式为阀板入炉时只装一排,放在炉子正中间,板与板之间的凹槽相对并彼此错开摆放,经此方式烧结后的阀板平面度为0.14mm,整形后可减小到0.07mm,与普通同类产品相比平面度减小30%左右。

| Abstract: | The iron-based valve plates used in refrigeration compressor were massly produced by powder metallurgy. The variation of flatness of the valve plates in sintering and shaping process with different method of loading was studied. The results show that the best order to place valve plate is that valve plate grooves are placed in opposite direction and stagger each other, the flatness of valve plate after sintering is 0.14 mm, the flatness of valve plate after shaping is 0.07 mm; The optimal placement is in th... |
