摘要
研究了热处理工艺对ＬＤ钢制作钢板弹簧中心孔冲头的力学性能和使用寿命的影响规律。结果表明，用ＬＤ钢制作钢板弹簧中心孔冲头，经１１２０°淬火、５４０℃高温回火处理后可以获得较好的力学性能；经１１４０℃淬火后深冷处理再在５４０℃高温回火，可以获得最佳的综合力学性能，其使用寿命比Ｃｒ１２ＭｏＶ钢作钢板弹簧中心孔冲头的寿命分别提高７倍和９倍。
The effect of heat treatment processes on mechanical properties and servicelife of centre hole punch made of LD steel for plate spring has been studied.The results show that good properties of the centre hole punch can be obtained by quenching from 1120℃ and high temperature tempering at540℃;optimal comprehensive mechanical properties can be got by quenching from 1140℃, subzero treatment and high temperature tempering at 540℃. The servicelife of centre hole punch made of LD steel is eight times and ten times than that made of Cr12MoV steel respectively.
