In order to ensure the stability of the machining accuracy, the hydraulic piston rod cannot be manually straightened during the whole process. The hydraulic piston rod is mostly used to withstand the alternating load, and the device reciprocates the surface. Therefore, the surface must meet the requirements of high hardness and wear resistance.
When selecting the positioning reference, the hydraulic piston rod can effectively ensure the coaxiality tolerance of the parts and the mutual positional accuracy of each part. All the machining processes can be positioned with two center holes. In order to ensure the machining accuracy, the piston rod is used. When turning, separate the rough and fine cars. Moreover, the coarse and fine cars are always used with the tool holder to reduce the deformation of the workpiece during machining, and the center frame should be remembered when machining the threads at both ends.
Advantages of hydraulic piston rod repair process
1. Repair welding: The advantages are simple construction, low repair cost and high efficiency.
2, electroplating: the advantages are simple maintenance technology, low cost, high production efficiency, good surface finish, suitable for batch processing.
3. Laser welding: The surface of the piston rod is made of laser to be wear-resistant and corrosion-resistant and then strengthened. The advantages are high deposition efficiency, smooth surface and long service life of the workpiece.www.xhychromerod.com
