摘　　要：通过叙述标准件冷镦生产过程中法兰面螺栓表面出现的贯穿性条纹的现象,充分分析了划痕产生的原因,以及带有划痕的冷镦盘条在生产中的遗传情况。探讨轧制线材的导卫装置、盘条粗拉润滑状态、拉丝模具导向区磨损情况三种因素对划痕的影响。提出划痕是由原材料的轧制过程中产生,拉丝模具以及粗拉润滑情况会对遗传程度造成影响。By describing the phenomenon of penetrating stripes on the surface of flange bolts in the production of standard parts cold heading,the causes of scratches and the heredity of cold heading strips with scratches are fully analyzed.The influence of three factors on the scratch is discussed:the guide device of rolling wire rod,the rough drawing lubrication state of wire rod and the wear of guide zone of drawing die.It is suggested that scratches are produced in the rolling process of raw materials,and the drawing die and rough drawing lubrication will affect the genetic degree.
