The invention discloses a forging process of a parachute snap ring. Comprising the following steps: (1) blank selection; (2) lathe worker blanking; (3) forging and pressing; (4) normalizing; (5) trimming; (6) turning an outer ring surface and an inner ring surface; (7) quenching and tempering; (8) sleeking by a lathe worker; (9) surface treatment; and (10) grinding and polishing are conducted, specifically, the part subjected to surface treatment is ground and polished, and a final product is obtained. According to the forging process, the annular blank is adopted, forging and pressing forming are conducted, forging defects are avoided, the forming effect is good, the end face turning procedure before forging and pressing is added, and the problem that end face burrs are forged and pressed into parts, and consequently the performance of the parts is affected is successfully solved.

    本发明公开了一种降落伞卡环的锻造工艺。包括以下步骤:(1)坯料选择;(2)车工下料;(3)锻压;(4)正火;(5)切飞边;(6)车外环面和内环面;(7)淬火和回火;(8)车工修光;(9)表面处理;(10)研磨抛光,将表面处理后的零件进行研磨抛光,得到最终的产品。本发明的锻造工艺采用圆环形的坯料,通过锻压成型,无锻造缺陷产生,成型效果好,且增加了锻压前车端面工序,成功解决了端面毛刺被锻压入零件内从而影响零件性能的问题。
