轴承保持架铆合模是由两件相同尺寸的模体(上模和下模)和导向装置组成,其球兜孔的中心径和铆钉窝的等分差都要求在0.02毫米以下,模具经过热处理后一般不再进行机械加工,因此要求采用比较合理的热处理方法,保证模体的变形值小于0.02毫米以满足使用要求。我们调查了行业内部分轴 Bearing cage riveting die is composed of two pieces of the same size of the mold (upper and lower mold) and the guide device, the center diameter of the pockets and rivets nest equally divided poor are required in 0.02 mm below the mold through After the heat treatment is generally no longer mechanical processing, requiring a more reasonable heat treatment method to ensure the deformation of the mold body is less than 0.02 mm to meet the requirements. We surveyed some of the industry’s internal axes
