一般来讲,随着钢中合金元素的增加,钢的机械强度指标、淬透性随之增加,冷变形性能随之降低。金相组织要求为使钢材能更好地适应冷镦工艺,对于钢的结构、晶粒大小与形式、非金属夹杂物的分布都有一定的要求。钢的组织结构钢中除了铁素体外,还有珠光体。含碳量越高,珠光体数量越多。铁素体是软的基体,在软的基体中嵌有硬的珠光体颗粒。成堆的珠光体分布对于冷变形是不利的,会形成裂纹。钢材的组织要紧密均匀,因此。冷镦用钢要用尽可能均匀分布、球状的晶粒结构。

一个良好的轴中控室和轴承公差,所以也应控制的圆度。轴承装配模式:由于skf轴承是高精度产品,如装配不当,容易损坏的通道轴承,导致轴承损坏。轴承在装配,应该有一个专门的模具,不能打败,推轴力只能是一个小圆圈,新闻界时仅受力的圈子。大会要求使用气压或液压,在压接上下模时,一级之外,如果该通道的斜率将导致交叉滚子轴承损坏,由于电力,离开生产的轴承的导环。装配异物的防止:轴承安装转子动平衡时很容易产生铁屑内的轴承安装前的动态平衡,所以做动平衡。
