Abstract
The present invention relates to a restoring method for damaged positions of main shafts of smoke machines in oil refineries. The present invention provides a new method aiming at the problem that damaged positions of main shafts of smoke machines are difficult to restore by the prior art. The present invention is characterized in that a three-dimensional five-linked numerically controlled machine tool is adopted; a restored main shaft is clamped in a three-dimensional space and rotates along the X direction, and a laser beam moves along the Y direction and the Z direction; the diameter of the light spot of the laser beam is 4.8 to 5.5mm, the power density is larger than or equal to 2.0*10<5>W/cm<2>, and the power is 2000 to 4000W. Casting materials can adopt powder, wires or plates. The present invention has the characteristics of high restoring precision, high restoring speed and low restoring cost. The present invention can be widely used in the mechanical restoring industry.
Description
The invention belongs to a kind of fast repairing method of oil plant smoke machine main shaft damage location.
Cigarette machine in the refinery catalytic cracking unit, main shaft adopt AISI1040 steel material to make, and geometric accuracy and technical performance index require very strict.Because main shaft turns round in the heat erosion environment for a long time, the corrosion of diameter of axle part is serious.Adopting machining to reduce diameter of axle size downgrades, the intensity of main shaft and creep rupture life index also along with decline, and thermofussion welding restorative procedures such as employing oxy-acetylene welding method, arc-welding method, submerged-arc welding method, argon arc welding method, main shaft matrix heat affected zone is big, damage and distortion reduce the main axe intensity index easily.Therefore, the traditional handicraft method does not all satisfy this type of spindle technology requirement of reparation.
Purpose of the present invention is to repair the difficult technologies problem at damaged area in smoke machine main shaft, has invented a kind of new method of utilizing laser to repair damage zone fast, and physical dimension form, matrix strength and the service life in main shaft local damage zone are restored fast; And high temperature resistance, anticorrosive and wear resistance after the reparation of raising main shaft damage zone.
A kind of laser method for fast repairing damaged area in smoke machine main shaft comprises it is characterized in that the operation such as Non-Destructive Testing, assessment, preliminary treatment, feeding, laser casting of main shaft worn area:
A. adopt three-dimensional coordinate five interlock Digit Control Machine Tools to carry out the laser casting reparation, main shaft radially rotates along directions X in three dimensions, and laser beam moves along Y, Z direction; The control laser beam is along the axially linear scanning of main shaft diameter local damage zone, and profiling is moved, and laser beam can be implemented single line or multi-track overlapping line sweep to the main shaft damage zone;
B. high-energy, high-density laser bundle are the circular or oval hot spot of Φ 4.8～5.5mm, laser power density 〉=2.0 * 10
5W/cm
2, laser power 2000～2500W;
C. the laser casting layer material is selected pulvis for use by main shaft material difference, and perhaps selecting the wire rod of φ 0.2～1.0mm and thickness for use is the sheet material of δ 0.2～0.8mm;
D. feeding style adopts conventional plane to preset, and perhaps adopts the synchronous feeding method of supersonic speed coating.
Good effect of the present invention is: the automaticity height, and operation easily, reparation speed is fast.Main shaft damage zone matrix is in repair process, and heating surface area is little, no thermal stress deformation; Can improve hardness and intensity after damage zone is repaired effectively, be a kind of advanced method of smoke machine main shaft wound repair, also is applicable to the reparation of various turning cylinder class damage workpiece, has very big economic worth and social benefit.
Embodiment 1
In factory of the petrochemical refining catalytic cracking unit energy-recovering machine group, the heavy wear of the YLII-6000A type smoke machine main shaft diameter of axle, bosom 1.5～2.0mm; Secondary thrust face wearing and tearing 0.3mm, there are the wearing and tearing of circular groove shape, degree of depth 1.0mm in diameter of axle oil sealing place.Adopt three-dimensional coordinate five interlock Digit Control Machine Tools to carry out the laser casting reparation, main shaft is fixed in the three dimensions, and along X to rotation, laser beam along Y, Z to moving, again by geomery mill repair, defect repair, polishing and a whole set of laser casting renovation technique of dynamic balancing, main shaft is carried out reconstruction; The laser casting power density is 2.0 * 10
5W/cm
2, power 2000～2300W, hot spot Φ 5.0～5.5mm, the scanning of multi-track overlapping line formula; Adopt and the similar sheet material of basic material, thickness is δ 0.2 material, feeding synchronously, and main axis rotation, laser beam is along the circular scanning of the damage zone diameter of axle.After molded layer reaches dimensional requirement, measure hardness and improve HRC 7～10, facts have proved: through the main shaft that the laser casting method is repaired, long-term operation time a year and a half under former work condition environment, reach the estimated performance index fully, the user is very satisfied.
Embodiment 2
Certain employed smoke machine main shaft of oil six factories, major injury is now repaired, and the employing method is as follows.
The damage main shaft is fastened in the three dimensions of five interlock Digit Control Machine Tools, and to rotation, laser beam moves along Y, Z direction main shaft along X, and laser beam power density is 2.0 * 10
6W/cm
2, power is 2200～2500W, hot spot Φ 4.8～5.2mm, the local comprehensive profiling motion scan of single line; Melt material adopts Φ 0.3mm wire rod; After molded layer reaches dimensional requirement, through mill repair, after the operation such as polishing, again through moving detect qualified after, renovation technique promptly finishes.On probation through the user, respond well.
