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
The present invention relates to the renovation technique of a kind of hydraulic cylinder piston rod.
Background technology
Solid particle enters friction between piston and cylinder barrel and causes that piston rod surface scratches, a series of mechanical damage is necessarily caused if repairing not in time, have a strong impact on transmission control and quality of fit, and the recovery scenario of existing hydraulic cylinder piston rod, and its procedure arrangement is unreasonable, operation is various, time is long, can not meet requirement, it is necessary to improved to improve performance.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide that a kind of operation is reasonable, simple to operate, the time is short, the renovation technique of the hydraulic cylinder piston rod of low cost of manufacture.
For achieving the above object, the invention provides the renovation technique of a kind of hydraulic cylinder piston rod, it is characterized in that, including following requirement:
(1) surface treatment: all of damaged location is heated with flame, by blend-out to all liquid being impregnated into metal depths or fluid, then with abluent cleaning piston bar, repeatable 4-5 time until piston rod on without any pollution, neat with drill bit processing at two of cut, then with the hand-held angle grinding machine equipped with suitable abrasive cut-off wheel, cut is widened along its total length, make repairing position become channel-shaped, again with abluent, all of position to be repaired is thoroughly cleaned；
(2) repair technology: healant is coated to surface treated position so that it is attach to well on the surface that polishing is coarse, then continue to coating material, till the material stacking layer formed at damaged location is slightly higher than its life size；
Etc. (3) after patching material is fully cured, then it is wide to recover original shape with the finishing of fine emery powder paper, to avoid damaging original chromium coating, it is impossible to other position around scratch when carrying out trimming operations.
The invention has the beneficial effects as follows: operation of the present invention is reasonable, each parameter collocation reasonable coordination, the time is short, simple to operate, improves service life, and then the loss of the time of minimizing and cost, quick, economical with the reparation of this method hydraulic cylinder piston rod, and effective.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described:
The renovation technique of a kind of hydraulic cylinder piston rod, is characterized in that, including following requirement:
(1) surface treatment: all of damaged location is heated with flame, by blend-out to all liquid being impregnated into metal depths or fluid, then with abluent cleaning piston bar, repeatable 4-5 time until piston rod on without any pollution, neat with drill bit processing at two of cut, then with the hand-held angle grinding machine equipped with suitable abrasive cut-off wheel, cut is widened along its total length, make repairing position become channel-shaped, again with abluent, all of position to be repaired is thoroughly cleaned；
(2) repair technology: healant is coated to surface treated position so that it is attach to well on the surface that polishing is coarse, then continue to coating material, till the material stacking layer formed at damaged location is slightly higher than its life size；
Etc. (3) after patching material is fully cured, then it is wide to recover original shape with the finishing of fine emery powder paper, to avoid damaging original chromium coating, it is impossible to other position around scratch when carrying out trimming operations.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.All technical staff in the art, all should in the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
