Problems solved by technology

[0002] Solid particles entering the friction between the piston and the cylinder lead to scratches on the surface of the piston rod. If it is not repaired in time, it will inevitably lead to a series of mechanical damage, which will seriously affect the transmission control and matching accuracy. The existing repair plan for the piston rod of the hydraulic cylinder, and its The process arrangement is unreasonable, the process is numerous, and the time is long, which can no longer meet the requirements and needs to be improved to improve performance

Embodiment Construction

[0009] The present invention will be further described below in conjunction with embodiment:

[0010] A repair process for a hydraulic cylinder piston rod is characterized in that it includes the following requirements:

[0011] (1) Surface treatment: heat all the damaged parts with a flame, melt all the liquid or oil impregnated deep into the metal, and then clean the piston rod with a cleaning agent, which can be repeated 4-5 times until there is no damage on the piston rod. As far as any pollution is concerned, use a drill to process both ends of the scratch neatly, then use a hand-held angle grinder equipped with an appropriate cutting wheel to deepen and widen the scratch along its entire length, so that the repaired position becomes a groove, and clean it again with cleaning agent. All parts to be repaired shall be thoroughly cleaned;

[0012] (2) Repairing process: Apply the repairing agent to the surface-treated part to make it adhere well to the rough surface, and th...

Abstract

The invention discloses a repairing technique for a piston rod of a hydraulic oil cylinder. The repairing technique includes the following requirements: (1) surface treatment: heating all the damaged parts through flame, melting out all the liquid or oil liquid dipped in the deep parts of metal, and cleaning the piston rod with a cleaning agent until all the pollutants are removed; machining two ends of a scratch orderly through a drill, deepening and widening the scratch along the whole length through a handheld angle grinder which is provided with a suitable cutting grinding wheel, allowing a repaired position to be groove-shaped, and cleaning all the parts to be repaired again through the cleaning agent; (2) a repairing technique: coating parts on which surface treatment is performed with a repairing agent, allowing the repairing agent to attach to the grinded rough surface, and then continuously coating the parts; and (3) repairing and recovering the parts into an original shape profile through fine emery paper after the repairing agent is solidified completely. The repairing technique is reasonable in processes, is low in cost, is reasonable and coordinated in parameter collocation, is short in time, and is simple in operation.

Description

technical field [0001] The invention relates to a repairing process for a piston rod of a hydraulic oil cylinder. Background technique [0002] Solid particles entering the friction between the piston and the cylinder lead to scratches on the surface of the piston rod. If it is not repaired in time, it will inevitably lead to a series of mechanical damage, which will seriously affect the transmission control and matching accuracy. The existing repair plan for the piston rod of the hydraulic cylinder, and its The process arrangement is unreasonable, the process is numerous, and the time is long, which can no longer meet the requirements and needs to be improved to improve performance. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is to provide a hydraulic cylinder piston rod repair process with reasonable process, simple operation, short time and low manufacturing cost....
