摘　　要：针对65Mn钢制弹簧夹头使用寿命较短问题,采用改进热处理工艺及更换新型材料GCr15钢制作弹簧夹头。对比试验结果表明,改进热处理工艺对提高弹簧夹头使用寿命效果不明显,而选用新型材料GCr15钢及规范的热处理工艺制作弹簧夹头,其力学性能及使用寿命均能显著提高,从而可以提高生产效率与产能。Aimed at the shorter service period of 65Mn spring cartridge, the heat treatment process was improved and new raw material GCr15 bearing steel was used in manufacture of the spring cartridge. Comparative tests show that the improved heat treatment process has no obvious effect on the worklife of spring cartridge. However, using new raw material GCrl5 bearing steel and an appropriate heat treatment process to manufacture the spring cartridge can greatly improve the mechanical properties and prolong worklife of the spring cartridge, thus the production efficiency and capacity are increased substantially.
