Description
Technical field
The present invention relates to cutter manufacture processing technique field, it particularly relates to which a kind of shear blade and scissors edge is hard
Change processing method.
Background technology
Scissors is instrument essential in daily life, still, it is desirable to which the hardness and abrasion resistance for making cutter blade edge reach
To desirable, it is necessary to very high cost.In the prior art, steel scissors hardness and wearability are good, but get rusty easily；Commonly
Although stainless steel scissors will not get rusty, hardness and wear no resistance, and high-quality stainless steel scissors cost is too high.How
It can manufacture that a kind of hardness and wearability are good, and the relatively low scissors of cost is the key that producer can get a profit.
The problem of in correlation technique, effective solution is not yet proposed at present.
The content of the invention
For the above-mentioned technical problem in correlation technique, the present invention proposes a kind of cure process of shear blade and scissors edge
Method, the cost of manufacture high-quality shear blade can be easily reduced, the shear blade hardness height of production, wearability are good, non-corrosive,
Production process low energy consumption.
To realize above-mentioned technical purpose, the technical proposal of the invention is realized in this way：
A kind of shear blade, including blade body, the blade body are provided with cutting edge, and the blade body is provided with groove, described
Groove is provided with alloy welding wire in the cutting edge and parallel with the cutting edge, the groove.
Further, the groove is U-shaped.
Further, the groove length is longer 1 ~ 2mm than the cutting edge.
Further, the width of the groove is 2 ~ 4mm, and depth is 1 ~ 2mm, between the groove and the cutting edge away from
From for 0.9 ~ 1mm.
Another aspect of the present invention, there is provided a kind of hardening process of scissors edge, comprise the following steps：
S1. one of U-shaped groove is extruded at cutting edge in blade body；
S2. alloy welding wire is melted into weldering by gas shielded weldering excessively to fill out in the U-shaped groove；
S3. cutting edge is ground sharp.
Further, instrument used in the step S2 is carried out as gas shielded welding machine, automatic wire feeder and automatic folder
Has frock.
Further, the U-shaped groove length is than the cutting edge（2）Long 1 ~ 2mm
Beneficial effects of the present invention：Shearing blade of the present invention, by setting groove and alloy welding wire, without using high-quality
Stainless steel can just strengthen the hardness and anti-wear performance of cutting edge, it becomes possible to obtain the cutting edge of preferable high rigidity and high abrasion degree
Steel layer.
The hardening process of scissors edge of the present invention, manufacture craft is simple, and investment is small, as long as gas shielded arc welding
Three machine, automatic wire feeder, automatic fixture frock equipment can complete cure process.
Be exactly an entirety from the appearance after shearing blade is ground, do not weld, splice or selective hardening heat treatment
Vestige.Production process energy consumption is small, pollution-free.Corresponding alloy can be selected according to the demand of different hardness and abrasion resistance
Welding wire, equipment are constant.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to institute in embodiment
The accompanying drawing needed to use is briefly described, it should be apparent that, drawings in the following description are only some implementations of the present invention
Example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be obtained according to these accompanying drawings
Obtain other accompanying drawings.
Fig. 1 is a kind of structural representation of shear blade described in the embodiment of the present invention；
Fig. 2 is the cross-sectional view of groove described in the embodiment of the present invention.
In figure：1. body；2. cutting edge；3. groove.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained, belong to what the present invention protected
Scope.
As shown in Figure 1 and 2, described a kind of shear blade according to embodiments of the present invention, including blade body 1, the blade sheet
Body 1 is provided with cutting edge 2, and the blade body 1 is provided with groove 3, and the groove 3 is close to the cutting edge 2 and flat with the cutting edge 2
OK, it is provided with alloy welding wire in the groove 3.
Which kind of specifically used alloy welding wire can be selected according to required hardness and anti-wear performance.Cutting edge 2 passes through
Alloy welding wire is strengthened, it becomes possible to forms high rigidity and the cutting edge steel layer of high abrasion degree.Without picture in the prior art, whole knife
Piece uses the stainless steel of high cost, greatly reduces production cost.
In a specific embodiment, groove 3 is U-shaped, shape phase during to set alloy welding wire with alloy welding wire
Coordinate, gap will not be produced.The length of groove 3 makes whole cutting edge 2 all be strengthened than the 2 long 1 ~ 2mm of cutting edge.The width of groove 3
It is 1 ~ 2mm to spend for 2 ~ 4mm, depth, and the distance between groove 3 and cutting edge 2 are 0.9 ~ 1mm.Certainly, the position of groove, length, width
Degree and depth can adjust according to the specific requirement of scissors.
The hardening process of scissors edge is illustrated below：
S1. one of U-shaped groove is extruded at cutting edge 2 in blade body 1；
S2. welded by crossing gas shielded（Crossing gas shielded weldering is by the use of gas as electric arc medium and protects the electricity of electric arc and weld zone
Arc-welding）Alloy welding wire is melted into weldering to fill out in the U-shaped groove, specifically, blade body 1 is fixed using automatic fixture frock,
Alloy welding wire is sent into U rows inside grooves using automatic wire feeder, alloy welding wire is melted weldering using gas shielded welding machine and fills out in U
In connected in star；
S3. cutting edge is ground sharp.
Because the characteristics of alloy welding wire so that melt postwelding blade and be no longer needed for carrying out quenching heat treatment, be directly entered and grind
Grinder sequence.By grinding, sharp cutting edge is ground.It is exactly an entirety from the appearance after ground, do not weld,
Splicing or the vestige of selective hardening heat treatment.
The hardening process of above-mentioned scissors edge replaces traditional quenching heat treatment, and production process is simple, and energy consumption is small, no
Produce pollution.
When extruding U-shaped groove, because the edge and blade cutting edge Edge Distance of U-shaped groove only have 0.9-1.0mm, so
After U-shaped groove extrudes, material wide 0.9-1.0mm can form a cutting edge projection toward outer displacement, and this is meeting in cutting edge grinding
It is worn away, just exposes the alloy material for melting weldering, forms high rigidity and the cutting edge steel layer of high abrasion degree.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
