我厂于1966年1月份学习了湖北齿轮厂这方面的经验,结合本厂情况创造性地用于了生产。在伟大的毛泽东思想指导下,坚持实行三结合,不断地改进提高。目前几乎所有的齿轮锻件全部实行了无飞边、无斜度锻造,均取得比较良好的效果。一、工艺欲得到无飞边的锻件,就必须采用闭式套筒模锻造,分模面应尽量取在毛坯的端面上,冲头与模套采用合理的间隙(D套—D冲=0.4～0.6)。无斜度锻件的主要特点是:内孔是直的(不
I plant in January 1966 to learn Hubei Gear Factory experience in this area, combined with the factory creative use of the production. Under the guidance of the great Mao Zedong Thought, we must insist on practicing the three principles and constantly improve and enhance it. Almost all of the gear forging all the implementation of a free edge, no slope forging, have achieved relatively good results. First, the process To get no flash edge forgings, it must be closed sleeve forging, parting surface should try to take the rough end, punch and die set with a reasonable gap (D sets-D red = 0.4 ~ 0.6). The main features of non-grade forgings are: the bore is straight (no
