Abstract
The invention discloses a carving knife die manufacturing technology and relates to the technical field of die cutting tools. An low-hardness steel plate is carved to form an initial knife point, the knife point is locally hardened through plasma electrode beam flames, and the knife point is fine carved after being hardened, smeared with grinding material and dried after being fine carved, and finally polished. The carving knife die manufacturing technology has the advantages that compared with a traditional knife die manufacturing technology, the hardness of the knife point is higher and can reach the HRC62 degree, and the hardness of the knife point of a knife die manufactured with the traditional manufacturing technology is HRC52 degree; the knife point is sharper and higher in degree of finish, the service life of the carving knife die is prolonged, and material cost is saved.
Description
[technical field]
The present invention relates to a kind of cross cutting instrument, in particular, the present invention relates to a kind of manufacture craft of engraving knife die.
[background technology]
Engraving knife die is a part for accurate cutting die, is applied to precision die cutting.So-called precision die cutting, dimensional accuracy is high, and appearance requirement is tight, and production lot is large, the cross cutting processing that quality requirements is stable.With laser cutter mould, aluminium sheet, the comparison of steel plate line cutter mould, precision die cutting possesses a little following: 1, size accuracy is high, and mould and die accuracy can be below ± 0.015, and general cutting die is not accomplished; 2, can do stripping behind, thicker for some materials, or the less product in stripping position, use stripping behind, allow waste material remove from the back of mould, be best selection; 3, can repeat the reconditioning knife edge, after the knife edge uses and sends out blunt, can return factory's rebuilding, be again a new cutter; 4, without any refuting cutter spacing, while having stopped to use common cutting die because refuting the cutter spacing product rejection causing that ftractures; 5, can carry out the designs such as different fabrication holes, step, impression, location, knife up.
The manufacture craft of existing engraving knife die is generally: with quenched SKD11 or DC53 trade mark mould alloy steel plate, its hardness is HRC52 degree left and right, carries out direct engraving and becomes cutting die.Because steel plate hardness is in HRC52 degree left and right, no matter be roughing, or the formation of blade, efficiency is all very low, and graver is easy to wear and cause graver not to be durable in the very short time content using, cause and change graver midway, and the knife edge surface ratio that engraving forms is more coarse, sharpness is poor.

D, Quenching Treatment, after roughhew has been carved, utilizing temperature is that 8000 DEG C of above plasma utmost point Shu Huoyan carry out Quenching Treatment to the initial knife edge, and plasma utmost point Shu Huoyan at the uniform velocity moves with 1.5-3 rice per minute, the hardness of the knife edge and the degree of depth of quenching can regulate to distance, the speed of the knife edge by the size of plasma utmost point Shu Huoyan or plasma utmost point Shu Huoyan, the depth of quenching of the knife edge is with 1mm-1.5mm the best, and after Quenching Treatment completes, knife edge hardness can reach HRC62 degree;
E, finishing impression, adopt single-blade taper graver, with cutting output 0.02mm, the knife edge carried out to finishing impression, and when finishing impression, blade rotating speed is more than 22000 revs/min, and process velocity is 0.7-0.9 m/min, and making knife edge top width is 0.05mm, and the finishing impression that completes the knife edge is carved;
F, smear dry and polishing, adopting resin material and polishing sand more than 150# to mix mixes well, mixed proportion is 1: 1, mixed mixture is applied on the knife edge, after this with plasma torch, the knife edge is dried fast, after oven dry, adopt taper graver to mill the mixture on the knife edge, can obtain the more smooth and sharp knife edge.
Preferably, in described steps A, the phosphorus content of steel plate is taking 0.6%-0.8% as good.
Preferably, in described step C, described single-blade engraving cutter is with the initial knife edge of speed carve of 7500 revs/min, and making initial knife edge top width is 0.1mm.
Preferably, described step D is: after roughhew completes, utilizing temperature is that the plasma utmost point Shu Huoyan of 8500 DEG C carries out Quenching Treatment to the initial knife edge, and plasma utmost point Shu Huoyan at the uniform velocity moves with 2 meters per minute, the hardness of the knife edge and the degree of depth of quenching can regulate to distance, the speed of the knife edge by the size of plasma utmost point Shu Huoyan or plasma utmost point Shu Huoyan, the depth of quenching of the knife edge is with 1.25mm the best, and after Quenching Treatment completes, knife edge hardness reaches HRC62 degree.
Preferably, described step e is: adopt single-blade taper graver, with cutting output 0.02mm, the knife edge is carried out to finishing impression, when finishing impression, blade rotating speed is 23000 revs/min, process velocity is 0.8 m/min, and making knife edge top width is 0.05mm, and the finishing impression that completes the knife edge is carved.
Beneficial effect of the present invention is: the manufacture craft of engraving knife die disclosed by the invention, adopt the soft initial knife edge of steel plate carve of hardness, then adopt plasma utmost point Shu Huoyan to carry out local stiffened to the knife edge, after stiffened, again the knife edge is carried out to finishing impression quarter, finishing impression is smeared oven dry with grinding-material again after carving, finally the knife edge is carried out to polishing, this kind of manufacture craft of the present invention, compare the manufacture craft of traditional cutting die, can make the hardness of the knife edge larger, reach HRC62 degree, and traditional manufacturing technique to produce the hardness of the knife edge of cutting die be HRC52 degree; The invention enables the knife edge more sharp, the fineness of the knife edge is also higher, has also improved the service life of engraving knife die, has saved material cost.
