1 活塞杆是粉末成型液压机中的组成部件之一，在设备运行过程中活塞杆也会发生相应的动作，但有时候却会出现拉伤、划伤或是击伤等不良现象。如果不对其进行及时的处理的话，会影响设备的正常使用。
2 当发现粉末成型液压机中的活塞杆受损之后，可以通过两种方式对其进行修复，一种是在线修复，还有一种是离线修复。对于不方便拆卸的活塞杆来说，可以在不解体的情况下对其进行在线修复，主要采用的是金属冷溶脉冲焊工艺。
3 Of course, the piston rod can also be removed from the powder forming hydraulic press and repaired by laser cladding. The specific operation mode is that the piston rod disassembled from the powder forming hydraulic press is placed on a lathe to remove the surface fatigue layer, and a layer of alloy layer is uniformly fused on the surface of the workpiece by laser cladding technology.
5 It should be noted that the thickness of the alloy layer on the piston rod should depend on the amount of the defect; then the piston rod after laser cladding should be machined to a standard size. If necessary, chrome plating can be carried out on the surface of the workpiece. After completion, the piston rod is loaded back into the powder forming hydraulic press in the correct way.
In short, the repair of piston rod of powder forming hydraulic press is a technology with high technical content, which needs to ensure dimensional accuracy, surface roughness, hardness, wear resistance, etc. Therefore, it is necessary to spray, cylindrical grinding and heat treatment. Only after comprehensive mastery can the piston rod be restored to its original appearance.
