Abstract：

It is difficult to forming accurate spur gears by the cold forging The two\|step forming technology combined closed die\|forging with constrained hole divided\|flow is presented The cold precision forging technology of spur gears are researched systematically for 15,45 and 20CrMnTi steel The results show that the two\|step forming technique is effective on decreasing cold precision forging load of spur gears and the cold forged 20CrMnTi steel spur gears have higher precision by applying the teeth\|shape modification method proposed
