1 Piston rod is powderforming hydraulic pressAs one of the components in, the piston rod will also have corresponding actions during the operation of the equipment, but sometimes there will be bad phenomena such as strain, scratch or injury. If it is not handled in time, it will affect the normal use of the equipment.
2 when foundPowder forming hydraulic pressAfter the piston rod in is damaged, it can be repaired in two ways, one is online repair, and the other is offline repair. For the piston rod which is not convenient to disassemble, it can be repaired online without disassembling, mainly using the metal cold dissolution pulse welding process.
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.
