Technical field
The present invention relates to a kind of laser cladding method, especially a kind of laser melting coating restorative procedure of die surface.
Background technology
Punching press is at room temperature, utilizes the press tool be arranged on pressing machine to apply pressure to material, makes it produce separation or viscous deformation, thus obtains a kind of pressure processing method of required part.Press tool is requisite tooling in punching production, is technological-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with die design and manufacture.Press tool is divided into blanking die, piercing die, bending die, Drawing Die, flaring die etc. according to technological property, these press tools are are all inevitably worn and torn in the course of the work, but because each mould role is different, stressing conditions during punching press is different, and the degree of wear in working process and wearing character are also different.Carry out die surface reparation by common overlaying method, the shortcomings such as deflection is large, hardness is not enough, easy to crack can be brought.And different moulds should select more suitable renovation technique according to its characteristic, otherwise the mold use life-span cannot be protected, and can have a strong impact on mold use precision, cause produced quality product to decline.
Laser melting coating refers to and is made it to melt with matrix surface skim through laser irradiation by coated material cladding matrix surface placed by selecting with different adding material modes simultaneously, and it is extremely low to form extent of dilution after rapid solidification, the top coat of metallurgical binding is become with matrix, the remarkable processing method improving the wear-resisting, anti-corrosion, heat-resisting, anti-oxidant of substrate surface and electrical specification, thus reach the object of surface modification or reparation.With built-up welding, spraying, plating and gas phase sediment-filled phase ratio, laser melting coating has that extent of dilution is little, dense structure, coating and matrix is combined, be applicable to that cladding material is many, granularity and the feature such as content is large.How laser melting and coating technique being effectively applied to the reparation of Drawing Die, is the problem that those skilled in the art needs to solve.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of surface to Drawing Die and carries out laser melting coating, makes the size of its surface hardness and abrading section reach the laser repair method of the Drawing Die of service requirements.
In order to solve the problems of the technologies described above, the invention provides a kind of laser repair method of Drawing Die, comprise following concrete steps:
The first step, the surface of Drawing Die to be repaired to be processed;
Second step, carry out detection analyze, determine abrading section and abrasion loss thereof;
The fatigue layer of the 3rd step, removal abrading section;
4th step, detection analytical results according to Drawing Die, programme to the die cavity of abrading section, formulates processing parameter;
5th step, built-up welding is carried out to abrading section form the first overlay cladding, then at the first layer overlay cladding enterprising windrow weldering formation second overlay cladding, the thickness of described first overlay cladding is 2mm to 3mm, the thickness of described second overlay cladding is 2mm to 3mm, in weld deposit process, constantly evenly knock mould alloy cladding layer, built-up welding adopts the mode of preset powder feeding, be that light source carries out lap connection scanning to mould with fast-transverse-flow CO2 laser, laser power is 1200W to 1400W, spot size is 12mm × 1.8mm, laser apparatus is 255mm to 265mm from the distance between Substrate, sweep velocity is 150mm/min to 180mm/min, amount of lap is 4.5mm, powder sending quantity is 8g/min to 11g/min, the component of the powdered alloy that the first overlay cladding adopts and weight percent content are C≤0.1%, Cr:15% to 19%, B:1.5% to 2.5%, Si:1% to 2%, Mo:0.8% to 1%, Mn:2% to 5%, all the other are Fe, the component of the powdered alloy that the second overlay cladding adopts and weight percent content are C≤0.1%, Cr:9% to 12%, B:1.5% to 2.5%, Si:1% to 2%, Mo:1.2% to 1.6%, Mn:5% to 7%, W:2% to 4%, V: 2% to 6%, TiO
2: 5% to 10%, all the other are Fe,
6th step, detection surface hardness and deflection, carry out mechanical workout, permeation flaw detection to the Drawing Die after repairing.
The mass percentage content of the Mn in the powdered alloy that above-mentioned second overlay cladding adopts is 5.6% to 6.6%.
The mass percentage content of the W in the powdered alloy that above-mentioned second overlay cladding adopts is 2.8% to 3.5%.
The mass percentage content of the V in the powdered alloy that above-mentioned second overlay cladding adopts is 4.2% to 5.8%.
TiO in the powdered alloy that above-mentioned second overlay cladding adopts
2mass percentage content be 6.3% to 8.7%.
The beneficial effect that the present invention brings is: the laser repair method of Drawing Die of the present invention is lower according to the wearing character of Drawing Die first built-up welding one deck hardness, wear resistance generally organizes the first overlay cladding that is comparatively fine and close, good uniformity, higher, good second overlay cladding of wear resistance of built-up welding one deck hardness on the first overlay cladding again, during the second overlay cladding built-up welding, the first overlay cladding does not still cool, and both all have selected suitable powdered alloy and carry out built-up welding, wettability between two overlay claddings is good, in conjunction with tightr.The content of the strict control C of the powdered alloy of the second overlay cladding, be conducive to the wettability improving cladding layer, prevent from cracking in cladding process and pore, add appropriate B, Si and make alloy form matrix based on austenite after solidification, utilize appropriate Cr, Mn, W, Mo, V, TiO
2carry out alloy strengthening to ferrous alloy, even if C content is lower, the hardness of cladding layer also can reach more than 55.5HRC, fully meets the hardness requirement that mould uses, and has very high wear resistance.Adopt the mode of preset powder feeding in addition, strictly control powder sending quantity, and laser power, sweep velocity, amount of lap etc. are optimized, such that the homogeneity of structure of cladding layer is good, thickness and hardness even.The method did not need to carry out preheating to mould before built-up welding, without the need to annealing to mould after built-up welding, effectively can control the distortion of mould, and heat can be avoided to concentrate generation thermal stresses by carrying out laser melting coating in an orderly manner everywhere, be conducive to reducing distortion further, improve hardness and the wear resistance of mould.
