摘　　要：借鉴国内外同类刀具结构,设计路面铣刨刀具5CrMnMo刀体锻造成形工艺,并给出锻造成形用模具设计过程,设计对扣式预锻和哈夫式终锻胎模。同时设计YG8硬质合金刀头与5CrMnMo刀体采用105钎料炉中气体保护钎焊的连接成形工艺。经测试所设计成形工艺能够使国产沥青砼路面铣刨刀具使用寿命达到国外相关产品使用寿命水平。In order to improve design and manufacture quality of domestic milling tool for asphalt concrete road surface, the forging process and die of tool body material is 5CrMnMo is designed according to the similar tool structure at home and abroad. Also, the joint process between tool head which material is YG8, a kind of cemented carbide, and tool body which material is 5CrMnMo is studied, and the braze welding that is protected by gas in 105 solder furnace can obtain good result. The life of the tool using the processing can achieve the level of Wirtgen tools.
