Abstract
The invention relates to a method for repairing an elevator cast iron traction wheel through fiber laser. Specifically, the method comprises the following processes: cutting and polishing a damaged part to 1mm through a machine tool, and cleaning a region to be cladded through acetone; preparing alloy powder according to the hardness of the elevator cast iron traction wheel, wherein a ratio of nickel base to iron base in the alloy powder is 6: 1; fixing the elevator cast iron traction wheel on an E2 axle of a working platform, and compiling programs of the machine tool according to a cladding position, wherein laser power is 2kw, a scanning speed is 200-400mm/min, a laser input angle is 45 degrees, a spot diameter is 3mm, an alloy powder conveying speed is 25g/min and am alloy powder conveying gas flow is 300L/h; switching on laser and cladding, spraying a colorant to inspect whether crack defects exist after cooling a cladding region, and carrying out mechanical processing after being qualified. The method, which repairs the elevator cast iron traction wheel through laser cladding, prolongs service life of the elevator cast iron traction wheel, brings about good economic benefit, and reduces production cost.
Description
Technical field
The present invention relates to elevator detection field, relate in particular to a kind of restorative procedure of optical-fiber laser to elevator cast iron traction wheel that utilize.
Background technology
Laser cladding technology is the technology of emerging a, fast development, it is under high-energy-density laser beam irradiation, matrix surface thin layer and the material adding as required (powdered alloy, silk material, flaky material) fusing simultaneously, forming thickness is 10～1000 μ m surface melting layers, the processing method that rapid solidification requires to meet a certain property is a new technology one of technology of prospect of the multidisciplinary intersections such as Elements Diffusion in set laser heat fused, molten bath, phase transformation effect and rapid solidification moulding.Utilize this technology can on low-cost matrix, prepare wear-resisting, anti-corrosion, high temperature resistant, anti-oxidant, heat insulation, insulation, etc. the surface strengthen layer of multiple property.The feature of laser cladding technology is: heat input is few, less to the heat affected zone of matrix effect, avoids repairing rear workpiece and produces large distortion and the generation of unrelieved stress; Thinning ratio is very little, and only matrix surface one deck fusing reduces the diluting effect of mother metal to coating material; Be easy to realize accurate control, shaping surface quality is better.
Elevator cast iron traction wheel in use can be subject to wireline rubbing effect, on both shoulders surface, dovetail groove both sides, occurs semicircle hole.Adopt arc surfacing heat input in the past large, elevator cast iron traction wheel easily causes workpiece cracking while being out of shape compared with Datong District, and the bonding strength of cold welding reparation, heat spraying method repair surface is not enough, in use, easily comes off.Yielding when elevator cast iron traction wheel reparation difficult point is reparation, cracking.
In view of above-mentioned defect, creator of the present invention has obtained this creation finally through long research and practice.
Summary of the invention
The object of the present invention is to provide a kind of restorative procedure of optical-fiber laser to elevator cast iron traction wheel that utilize, in order to overcome above-mentioned technological deficiency.
For achieving the above object, the invention provides a kind of restorative procedure of optical-fiber laser to elevator cast iron traction wheel that utilize, this specific embodiment is:
Step a,, cleans up region to be deposited with acetone 1 millimeter of damage location cutting polishing with lathe;
Step b, according to the hardness modulation alloy powder of elevator cast iron traction wheel, Ni-based in alloy powder, iron-based proportioning is 6: 1;
Step c, elevator cast iron traction wheel is fixed on worktable E2 axle, according to deposited position, finish machine tool program, laser power is 2 kilowatts, sweep velocity is 200～400 mm/min, laser input angle 45 degree, and spot diameter is 3 millimeters, carrying alloy powder speed is 25 gram/minute, carries 300 ls/h of alloy powder gas flows;
Steps d, opens laser and carries out depositedly, and after district to be deposited is cooling, whether spray colouration agent inspection has crack defect, carries out mechanical workout after qualified.
Further, in above-mentioned steps c, elevator cast iron traction wheel is fixed on worktable, adjusts the position of laser focused head, regulate size and the spot center of hot spot to be positioned at deposited place.
Further, in above-mentioned steps d, carry a small amount of alloy powder carry out second time deposited.
Beneficial effect of the present invention is compared with prior art, the present invention uses the method for laser cladding to repair elevator cast iron traction wheel, select the alloy powder material close with mold material as coating material, guarantee that deposited district and not deposited district Hardness Distribution are even, the distortion of laser cladding rear mold is little, on the not impact of the base material in other region, laser cladding alloy powder material is filled damaged zone can control the thickness of overlay well; In the work-ing life that has extended elevator cast iron traction wheel, produced good economic benefit, reduced production cost.
