Abstract
The present invention belongs to a complete set of technology for restoring the rigidity of a stone cutting disc saw, which has the main steps of the surface pretreatment of old saw blade base materials, mechanical leveling, surface blackening, reinforcing bar treatment by laser application, mechanism leveling, tension degree adjustment, surface coating, etc. Thus, old saw blade base materials which have high rigidity than new saw blade base materials can be obtained by the method. With simple technology and easy processing and manufacture, the present invention is good for collecting and using old base materials of stone cutting disc saws, and has remarkable economic benefits.
Description
The invention relates to a kind of restorative procedure of the disc-saw base material rigidity that cutting stone material uses, mainly be applicable to the reparative regeneration of the disc-saw base material of being scrapped because rigidity descends in the present processing of stone.
Widely used circular saw in present processing of stone, it is that (diameter is from 300mm～3000mm, thickness 1.0mm～13mm) and go up diamond abrasive point in its peripheral soldering (or melting welding or inlay) and form by the saw blade base material.Can change repeatedly after the bistrique wearing and tearing, but the base material of circular saw rigidity after the certain hour operation descends, deliquescing, under the high speed rotation, serious beat and distortion easily take place, scrap therefrom, cause a large amount of waste of steel, the decline of processing of stone quality and the raising of cost.
For these are only utilized again because of the disc-saw base material that rigidity decline is scrapped, the objective of the invention is, a kind of process of reparation stone-cutting disc-saw rigidity is provided, utilizes the method can realize repairing rigidity of base material, utilize again to reach the purpose of recycling.
The present invention's process flow process is: (its technological process as shown in drawings)
(1) the surperficial pre-treatment of saw blade Ji Shu: processing comprises sandblast, and steel brush cleaning and sand paper grind;
(2) mechanical planarization: comprise hammering, machinery flattens;
(3) surperficial melanism: comprise spray carbon dust, prepared Chinese ink and oxide paint;
(4) laser charity sclerosis reinforcement is handled:
(5) machinery smoothing: comprise that hammering beats;
(6) tension adjustment: comprise the rigidity and the deformation measurement in base material constituency, along circumferentially striking with reconnaissance hammering radially
Beat;
(7) rigidity detects;
(8) external coating;
Wherein the processing of laser charity sclerosis reinforcement is to adopt laser surface rapid quenching method to form centrosymmetric sclerosis reinforcement (degree of depth is 0.1mm～2.5mm, width 0.1mm～40mm, hardness HRC35～70) in the two sides of disc-saw base material.
Laser irradiation conditions is:
Laser generator CO2, Nd-YAG, Cu steam
Laser irradiation power P 200w～20000w
Second beam flying speed V 10mm/ second～1m/
Exposure beam focused spot diameter D 0.1mm～40mm
The beam motion mode: by the rectilinear motion at base material center with the base material center is the circular arc fortune in the center of circle
Moving, can carry out the asynchronous irradiation of priority or two-sided synchronous to two big sides of base material
Irradiation.
It can be the side of elder generation from saw blade that laser charity reinforcement is handled, and then the another side, also can be simultaneously the two sides of saw blade base material to be carried out, and the saw blade edge suitably presses folder can reduce its distortion effectively.
The present invention's advantage: method is simple, handling ease, and easily automation facts have proved that the reparation of adopting this process to carry out rigidity of stone-cutting disc-saw base material is effective.
The present invention's embodiment:
Example 1: cut-off directly is 1.6M, thickness is the old stone-cutting disc-saw base material of 6mm, arborescence is 65Mn, and it has cut 450 square metres of stone materials, and the 3.5mm distortion takes place base material, other defective such as flawless, because surface corrosion is serious more than 1 year the place resting period outside, after the process reparation is overlapped in rust cleaning-smooth-melanism-laser-smoothing-tension adjustment-encapsulation such, mail to the stone pit and use three surplus moons, change bistrique four times.
The laser irradiation parameter:
Laser irradiation mode: base tree two surperficial asynchronous irradiation
Laser instrument: 5KW CO
2
Luminous power P:2500W～5000W
Second optical scanning speed V:35mm/ second～70mm/
Exposure light spot diameter D:2.5mm～4.5mm
Sclerosis reinforcement hardness: HRC 40～65
The sclerosis reinforcement degree of depth: 0.2mm～1.0mm
Example 2: cut-off directly is 2.2M, the Italian stone-cutting disc-saw base material of thickness 5.5mm import, it has changed four diamond abrasive points of weldering, base material is deformed into 2.0mm and is scrapped, but other defective such as flawless, the surface non-corroding after the such cover process reparation of smooth-melanism-laser-smoothing-tension adjustment-encapsulation, returns certain processing of stone factory and has cut southern granite so far more than 500 square metres.
The laser irradiation parameter:
Laser mode: base material two surfaces are irradiation synchronously
Laser instrument: 5KW CO
2
Luminous power P:3000W～4000W
Second optical scanning speed V:20mm/ second～80mm/
The irradiation stigma is rectangle (long * wide): 3 * 3mm～10 * 1.5mm
Hardenability band hardness: HRC, 42～65
Hardenability band layer depth: h, 0.5～1.5mm
The present invention is equally applicable to the reparation of the rigidity of other cold cut saw blade base material, as steel plant cut the steel saw blade, in the wood-processing industry with cutting wooden saw blade etc.
