再制造液压缸应按图样和再装配工艺规程进行装配,装配到再制造液压缸上的零部件(包括再制造零部件、更新件)均应符合质量要求。活塞杆的再制造(1)采用特殊的退镀工艺对镀铬层进行处理,修复后重新镀铬。(2)把杆径做一定的调整,定制相应的密封件和端盖,同时对杆体进行热处理强化,提高杆体的机械强度,降低再制造的成本。(3)对于表面损坏严重的活塞杆,使用冷焊机进行局部焊接,修复损坏缺陷;同时我们也可以利用等离子激光淬火,使活塞杆杆体尺寸变化,然后整体重新加工。等离子激光淬火
Remanufactured hydraulic cylinders shall be assembled according to the drawing and reassembly procedure, and the parts assembled to remanufactured hydraulic cylinders (including remanufactured parts, updates) shall meet the quality requirements. Piston rod remanufacture (1) The use of a special stripping plating process chromium plating, repair and chrome plating. (2) to make some adjustments to the rod diameter, customize the corresponding seals and end caps, while the rod body heat treatment to strengthen and improve the mechanical strength of the rod to reduce remanufacturing costs. (3) For the piston rod with serious surface damage, use the cold welding machine for partial welding to repair the damage defect; meanwhile, we can also use the plasma laser to quench the piston rod body size, and then re-processing the whole. Plasma laser quenching
