Description
【Technical field】
The present invention relates to a kind of cross cutting instrument, more particularly, it relates to a kind of manufacture craft of engraving knife die.
【Background technology】
Engraving knife die is a part for accurate cutting die, applied to precision die cutting.So-called precision die cutting, i.e. dimensional accuracy are high,
Appearance requirement is tight, produces of large quantities, the stable cross cutting processing of quality requirements.With laser cutter mould, aluminium sheet, steel plate line cutter mould ratio
Compared with, precision die cutting possess it is following a little：1st, dimensional accuracy is high, and mould and die accuracy can be that general cutting die is done below ± 0.015
Less than；2nd, behind stripping can be done, it is thicker for some materials, or the less product in stripping position, using behind stripping, allow useless
Expect to remove from the back of mould, be optimal selection；3rd, the reconditioning knife edge is repeated, i.e., after knife edge use is sent out blunt, factory's rebuilding can be returned,
It is a new knife again；4th, refute cutter spacing any, prevented using during common cutting die because refute cutter spacing cracking and caused by product report
It is useless；5th, the design such as different fabrication holes, step, impression, positioning, knife up can be carried out.
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 or so, carries out direct engraving into cutting die.Because steel plate hardness is in HRC52 degree or so, either slightly
Processing, or blade formation, efficiency is all very low, and graver is easy to wear and cause carving in the very short time content used
Icking tool is not durable, and causes midway to change graver, and carves that the knife edge surface of formation is relatively rough, sharpness is poor.
【The content of the invention】
It is an object of the invention to effectively overcome the shortcomings of above-mentioned technology there is provided a kind of so that the knife edge is sharper, the knife edge
The manufacture craft of the higher engraving knife die of finish.
The technical proposal of the invention is realized in this way, and it is theed improvement is that, the technique comprises the following steps：
A, selection, from phosphorus content 0.5%-0.9% middle carbon high-quality electric furnace hot rolled steel plate；

The standard thickness wanted；
C, roughhew, are held the steel plate carried out after polishing processing by the sucker of engraving machine, and carried out using four blade milling cutters
Roughhew, during roughhew, the rotating speed of the head of engraving machine is 8000 revs/min, and the height that can be needed according to the knife edge is reserved with angle
The width and depth of knife edge finishing, hereafter, are carved out initially using single-blade engraving cutter with more than 7000 revs/min of speed
The knife edge, and cause initial knife edge top width to be 0.1-0.15mm；
D, Quenching Treatment, after the completion of roughhew is carved, using the plasma pole Shu Huoyan that temperature is more than 8000 DEG C to initial knife
Cutting edge of a knife or a sword carries out Quenching Treatment, and plasma pole Shu Huoyan is at the uniform velocity moved with 1.5-3 meters per minute, the hardness of the knife edge and the depth of quenching
It can be adjusted by the distance of plasma pole Shu Huoyan size or plasma pole Shu Huoyan to the knife edge, speed, the knife edge
After the completion of the depth of quenching is 1mm-1.5mm, Quenching Treatment, knife edge hardness is HRC62 degree；
E, finishing impression, using single-blade taper graver, finishing impression, blade rotating speed during finishing impression are carried out with cutting output 0.02mm to the knife edge
For more than 22000 revs/min, process velocity is 0.7-0.9 ms/min so that knife edge top width is 0.05mm, that is, completes knife
The finishing impression of cutting edge of a knife or a sword is carved；
F, smearing drying and polishing, carry out mixing using resin material and 150 more than ﹟ polishing sand and mix well, mix
Ratio is 1:1, mixed mixture is applied on the knife edge, hereafter quickly dried the knife edge with plasma torch, is dried
Afterwards, the mixture on the knife edge is milled using taper graver, you can obtain the more smooth and sharp knife edge.
Preferably, in the step A, the phosphorus content of steel plate is preferred with 0.6%-0.8%.
Preferably, in the step C, the single-blade engraving cutter carves out the initial knife edge with 7500 revs/min of speed,
So that initial knife edge top width is 0.1mm.
Preferably, the step D is：After the completion of roughhew, using the plasma pole Shu Huoyan that temperature is 8500 DEG C to initial
The knife edge carries out Quenching Treatment, and plasma pole Shu Huoyan is at the uniform velocity moved with 2 meters per minute, and the hardness of the knife edge and the depth of quenching can
To be adjusted by the distance of plasma pole Shu Huoyan size or plasma pole Shu Huoyan to the knife edge, speed, the knife edge is quenched
Fiery depth is optimal with 1.25mm, and after the completion of Quenching Treatment, knife edge hardness reaches HRC62 degree.
Preferably, the step E is：Using single-blade taper graver, finishing impression, essence are carried out to the knife edge with cutting output 0.02mm
Blade rotating speed is 23000 revs/min during carving, and process velocity is 0.8 m/min so that knife edge top width is 0.05mm, i.e., complete
Finishing impression into the knife edge is carved.
The beneficial effects of the present invention are：The manufacture craft of engraving knife die disclosed by the invention, using the soft steel plate of hardness
The initial knife edge is carved out, then the knife edge is carried out using plasma pole Shu Huoyan to carry out essence to the knife edge again after local stiffened, stiffened
Engraving, finishing impression carries out smearing drying with grinding-material again after carving, and finally the knife edge is processed by shot blasting, such a making work of the invention
Skill, compared to the manufacture craft of traditional cutting die, may be such that the hardness of the knife edge is bigger, reach HRC62 degree, and traditional manufacturing technique makes
The hardness for going out the knife edge of cutting die is HRC52 degree；More sharp the invention enables the knife edge, the finish of the knife edge is also higher, also improves
The service life of engraving knife die, has saved material cost.
