Detailed description of the invention
Technical scheme in the present invention is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of protection of the invention.
Please refer to Fig. 1, embodiments provide a kind of hydraulic cylinder restorative procedure.The hydraulic cylinder restorative procedure provided comprises the following steps:
S100, determine the damage field of hydraulic cylinder.
The object of this step is by eye-observation or Equipment Inspection, finds the abraded area on hydraulic cylinder to determine damage field.Concrete, failure area may occur in the surface of the inwall of oil cylinder, the surface of piston or piston rod.
S200, to damage field implement cleaning.
As described in the background art, the operating environment of field of metallurgy is poor, and therefore damage field often can exist the material that dirt, oxide layer etc. affect subsequent handling operation, therefore needs to implement cleaning to damage field.
Please refer to Fig. 2, a kind of detailed description of the invention that Fig. 2 is shown to damage field enforcement cleaning, specifically comprises the steps:
S210, to damage field implement cleaning, with wipe oil.
Usually implement physical cleaning and Chemical cleaning to damage field, physical cleaning first washes the dust, wear debris etc. of damage field, then implements cleaning in employing Chemical cleaning to the greasy dirt of damage field etc.The object of this step guarantees the cleannes of damage field, to guarantee that clear border, the factory interface of machined surface are clearly convenient to follow-up soldering.
S220, to through cleaning after damage field implement shaping, to determine the edge of damage field.
This step is on the basis of cleaning step, and further clear and definite damage field, the edge of the area to be machined namely in subsequent step, this can ensure the accuracy of processing preferably.In a kind of concrete embodiment, step S220 is the oxide layer removing damage field after cleaning.
For the ease of in follow-up soldering operating process, the fastness of solder solidification, in preferred scheme, can also comprise after step S220: offer multiple stepped depression damage field is discrete.This stepped depression makes the surface of damage field not in same plane, and then solder can solidify at the faying face of damage field differing heights when making follow-up soldering, and then improve the fastness of solder solidification, improve the intensity after the reparation of subsequent insult region further.
S300, employing differential of the arc solder technology implement soldering to damage field.
This step adopts differential of the arc solder technology to implement soldering to damage field.Differential of the arc solder technology is on traditional argon arc welding basis, innovate a class solder technology of research and development; the equipment implementing differential of the arc solder technology mainly comprises the pulse power, protective gas inert gases such as () such as argon gas and is used for filling up the wire of damage field, i.e. solder.In welding process, wire melts by the electric arc utilizing welding gun to produce, and with protective gas molten metal drop is blown and is mapped in the damage field of workpiece, thus fill and lead up the damage field after step S200 process.
Differential of the arc welding has the following advantages: the first, can realize accurate soldering.Repair requirement according to scuffing, determine the parameter of soldering, the differential of the arc to be welded on when electric current is less than 10A electric arc still can flameholding, there will not be wandering phenomenon.The welding wire of more than 0.5mm can be used, and then obtain comparatively accurate repair welding parts.The second, the heat affecting produced is less.Because the arcing time of differential of the arc welding and electric current can control, electric arc be cylindricality, and therefore electric arc to a certain degree just changes affects very little on the heating surface (area) (HS of damage field, parts is heated drop to minimum, can not produces distortion.When three, adopting the differential of the arc welding arcing time of welding machine and electric current all very low, and then the damage to damage field in welding repair process can be avoided.Four, due to starting the arc concentration of energy, welding efficiency is higher, and postwelding weldquality is higher, can reach the effect of argon welding.Also be that protective gas blows molten metal drop and is mapped to damage field position, there will not be that soldering is insecure, come off problem.Five, differential of the arc welding is easy to operation, and can adapt to more quality welding wires to implement soldering, soldering becomes the solder joint of different hardness.
S400, shaping polishing is implemented to the soldering of the damage field through soldering surface.
The object of this step is, implements shaping polishing to the soldering surface of damage field, and then guarantees that the soldering surface of damage field is consistent on the default surface of damage field with hydraulic cylinder, and that is the surface of damage field is by consistent with damaged front parameter.
Please refer to Fig. 3, Fig. 3 shows a kind of detailed description of the invention soldering surface being implemented to shaping polishing, and this embodiment comprises the following steps:
Thick polishing is implemented on S410, the employing file soldering surface to damage field.
S420, with oilstone, meticulous polishing is implemented to the soldering surface through thick polishing.
By thick and thin mode, above-mentioned substep polishing, can ensure that polishing surface reaches preset requirement better, more quickly.
In the hydraulic cylinder restorative procedure that the embodiment of the present invention provides, determine the damage field of hydraulic cylinder and adopt differential of the arc solder technology to implement soldering to damage field to after damage field enforcement cleaning, through polishing with the reparation guaranteeing damage field after soldering.In above-mentioned restorative procedure, differential of the arc welding can ensure the accurate soldering to damage field.The restorative procedure adopting the embodiment of the present invention to provide can avoid outer committee to repair or scrap process also again to the situation generation that manufacturer orders, therefore, above-mentioned restorative procedure can solve the problem that rehabilitation cost is higher and remediation efficiency is lower of the hydraulic cylinder described in background technology.
Based on the hydraulic cylinder restorative procedure that the embodiment of the present invention provides, the embodiment of the present invention also provides a kind of hydraulic cylinder, and the hydraulic cylinder provided has damage field, and this damage field is for forming soldering region by the restorative procedure reparation above described in any one embodiment.
Herein, only emphasis describes each preferred version is different from other scheme, each preferred version only otherwise conflict, can be combined, within the category of the embodiment formed after combination also disclosed in this description, considering that text is succinct, just no longer describing separately combining the embodiment formed herein.
