摘　　要：针对65Mn钢制弹簧夹头使用寿命较短,采用改进65Mn钢的热处理工艺及更换新型材料GCr15钢制作弹簧夹头。对比试验表明,改进65Mn钢的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。In view of the shorter service period of 65 Mn spring cartridge, methods of improving 65 Mn heat treatment process and adopting new raw material bearing steel GCrl5 are used in manufacture of the spring cartridge. Comparative tests show that the improvement of 65Mn heat treatment has no obvious effect on the service period. However, using new raw material bearing steel GCr15 and formulating an appropriate heat treatment process in manufacture of the spring cartridge can prolong the mechanical properties and service period greatly, thus the production efficiency and capacity are increased substantially.
