Plum coupling锻件如何做到无损检测
1、 梅花Coupling锻件一般要求应无裂纹、白点、折叠、严重的锭型偏析和严重的非金属夹杂物。 2、 梅花联轴器锻件超声波检验按JB/T1581-1996或JB/T1582-1996的规定进行。超声波控伤其要求如下: A. 当量直径小于2mm的单个分散的缺陷不计,但应记录,并报告需方; B. 不允许有当量直径大于5mm缺陷存在;我厂生产齿式联轴器. C. 如有密集缺陷,双方协商处理。 3、 当需方的锻件图样上有规定时,锻件磁粉检验应在精加工后按JB/T6063-1992的规定进行。磁粉检验其要求如下: A. 长度不小于1mm的缺陷应记录其位置; B. 不允许有长度大于5mm的缺陷性的磁粉堆积存在;我厂生产弹性柱销联轴器. C. 位于同一母线上的线性缺陷间的距离小于其中较大缺陷长度的3倍时,按一条计; D. 长度大于5mm的缺陷,在图样规定的公差范围允许局部磨去,抛光后重新检验。 4、 梅花联轴器锻件金相试验按YB/T5148-1993的规定测定晶粒度,实际晶粒度不得粗于4级。 5、 梅花联轴器锻件的尺寸和表面粗糙度应符合需方提供的图样的规定。选Diaphragm coupling到XinLan.
