Description
Technical field
The present invention relates to kitchen tools processing technique field, and in particular to a kind of manufacture craft of anti-adhesion cutting knife.
Background technology
The cutting knife species of commercial type circulation at present is various, from function or all varied in appearance.It is all
Cutter can meet cutting function, but problems be present：
1. the easy rust of the knife edge is, it is necessary to frequently polish；
2. during cutting the dish, knife face is easily adhered dish block；
3. easily being got rusty during use, service life is short etc..
Problem above, be because caused by cutting knife selection, manufacture method, such as existing cutter more from stainless steel and
For ordinary carbon steel as making material, the hardness of material is inadequate, causes knife edge rust or turned situation during use to occur, and
Ordinary carbon steel easily gets rusty；Existing tool sharpening only with simple cold rolling or forging, polish, step, the material grains such as put the first edge on a knife or a pair of scissors it is thick
Rough loose, the easy rust of the knife edge, blade easily collapses damage, curling etc.；Furthermore existing cutter knife face is mostly smooth moulding, causes to cut the dish
Delicacies of the season block adheres to knife face.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of manufacture craft of anti-adhesion cutting knife, its superior materials, technique
The means closed from high-temperature heating and disease cold junction so that product hardness and pliability are all good, and shape-designing is reasonable, and in cutter
Anti-sticking groove is designed on surface, solve thes problems, such as that knife face adheres to during cutting the dish.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of manufacture craft of anti-adhesion cutting knife, its manufacture craft comprise the following steps：
Step 1 cuts out steel cold-rolling to certain thickness for required shape, forging forming, punching press knife face groove, and go
Except knife face metal oxide layer, crude green body one is obtained；
The crude green body one is put into vacuum furnace by step 2, is heated to temperature one, duration one is kept, by the crude green body of high temperature
One is put into cooling in isothermal salt bath, and disease is cooled to temperature two, and is incubated duration two, and crude green body one is taken out and is cooled to room temperature, clear water
Cleaning, obtains crude green body two；
Crude green body two is heated to 180 DEG C by step 3, and is incubated 2 hours, and heating is cooled to room temperature after terminating, put the first edge on a knife or a pair of scissors mouth and essence
Grinding and polishing light, obtain crude green body three；
Crude green body three is put into liquid nitrogen deep case by step 4, is cooled to temperature three and is incubated duration three.
Step 5 takes out crude green body three from liquid nitrogen deep case, returns and warms to room temperature, and crude green body three is heated into 100-120 DEG C, protected
60min is held, is cooled to room temperature, it is polished, hilt is assembled, laser machine mark, obtains finished product.
As preferable, in step 1, by steel cold-rolling to 1.8-2.0mm.
As preferable, in step 1, by steel cold-rolling to 2.0-2.2mm.
As preferable, in step 1, punch diameter used in punching press knife face groove is 2.2mm.
As preferable, in step 1, a diameter of 0.2-0.6mm of groove, center spacing is 15mm.
As preferable, in step 2, temperature one is 1020 DEG C, and duration one is 120min；Temperature two is 255-265 DEG C,
Duration two is 4 hours.
As preferable, in step 4, temperature three is -190 DEG C, and duration three is 1.5-2 hours.
As preferable, in step 4, duration three is 2 hours.
As preferable, in step 2, salt made from earth containing a comparatively high percentage of sodium chloride is placed in isothermal salt bath.
As preferable, in step 1, steel type 9Cr18Mo/440C.
The present invention uses above-mentioned technical proposal, and the beneficial effect brought is：
Selection of the present invention is 9Cr18Mo/440C model steel, and the model steel hardness is high and wearability is good, corrosion resistance
And good-toughness；In the step 2, by crude green body one at 1020 DEG C of vacuum condition, 120min is heated, and in isothermal salt bath
Disease is cooled to 255-265 DEG C, and vacuum condition first avoids the surface of crude green body one in heating process from oxide layer occur, influences material density,
Furthermore material grains are effectively refined, have improved the hardness, wearability and corrosion resistance of material；In the step 5, to thick
Base three carries out superfreeze, further refines material crystal grain, improves the hardness, wearability and corrosion resistance of material；It is described
In step 1, in crude green body a pair of surface stamped recess so that the existing pit in final products surface, have projection again, effectively avoid cutting
Dish block adheres to the problem of knife face during dish.
