Description

Simple steel rust-resisting kitchen knife

The utility model belongs to human cooking operation cutter.

The cooking cutter that the human lives is essential, two big classes are arranged at present: a class is the carbon steel kitchen knife, and common is common with the folder steel kitchen knife, and the carbon steel cutter of manufacturing with clean steel is seldom.The carbon steel knife is with low-carbon (LC) forging folder medium carbon steel, or direct commodity in use clad steel, makes through technologies such as forging rollings.Second class is the stainless steel kitchen knife, and general corrosion resistant plate is made through technologies such as stamping-outs.With the knife is the carbon steel kitchen knife of representative, and the history in more than 1,000 year is arranged, have sharp, the inexpensive and advantage sharpened certainly; But easily get rusty, yellow rust staining spot, the dirty food that becomes rusty again neither attractive in appearance, boring.Most of stainless steel kitchen knife surface aesthetic, antirust ability strengthens; The user often feels cutting edge and feels numb and not sharp but blade is easily pure, and price is also more expensive.Because these shortcomings of stainless steel kitchen knife, it fails to replace the ordinary carbon steel cutter.For these years, each kitchen knife manufacturer adopts several different methods to improve the antirust ability of ordinary carbon steel cutter, all technologies such as blackout, zinc-plated, chromium plating were all tested, can be all abominable because of the environment for use of kitchen knife, often contact water, salt, acid, alkali and perishable materials such as CO2 and SO2 make it promptly lose antirust ability within the several months.The antirust problem of ordinary carbon steel kitchen knife has become a great problem for these years.

The purpose of this utility model is to provide a kind of not only sharp durable but also stainless new-type popular rust prevention kitchen knife attractive in appearance for consumers in general.

Inventor of the present utility model has taked on the surface of ordinary carbon steel kitchen knife through for many years experimental study, is coated with and oozes the last layer aluminum or aluminum alloy, makes it form antirust coat, and the protection kitchen knife no longer gets rusty, and has solved the difficult problem that the carbon steel kitchen knife gets rusty.Release a kind of advantage that has carbon steel cutter and stainless steel knife concurrently, and overcome the novel Simple steel rust-resisting kitchen knife of the two deficiency.The rust-proof mechanism of Simple steel rust-resisting kitchen knife is: by being coated with alumetizing process, making to ooze on the surface of carbon steel cutter and covered one deck aluminum or aluminum alloy.Aluminium is active, at high temperature with iron generation alloy reaction, generates the layer of aluminum iron alloy layer on the surface of kitchen knife, and it has very strong resistance to corrosion.Unnecessary aluminum or aluminum alloy cover again alloy-layer above, form rich aluminium lamination, novel kitchen knife is in the process of using, outermost rich aluminium lamination is hard fine and close pellumina because of oxidation generates.Under the duplicate protection of this layer pellumina and alfer layer, the surface of kitchen knife can corrosion; The aluminium atom of bottom also can not penetrate oxide-film and dissociate in food, and safety and sanitation are harmless to human health.Facts have proved that the antirust ability of novel kitchen knife is more than 10 years.Because novel cutter no longer gets rusty, the cutter hub light is attractive in appearance.The user does not again need expensive energy to go worn rust dirty during sharpening, brings great convenience to sharpening, and be more than 2 times of ordinary carbon steel cutter the service life of new cutter.Novel kitchen knife does not have to adopt more expensive stainless steel material, and cost is 60% of the stainless steel knife of same specification only, has economy.The utility model is released is the popular human cooking cutter of a kind of not only sharp stainless but also inexpensive longevity.

Description of drawings: Fig. 1 is the profile schematic diagram of Simple steel rust-resisting kitchen knife.Fig. 2 is the cutter hub cross section A-A enlarged drawing of folder die.Fig. 3 is the cutter hub cross section A-A enlarged drawing of clean steel type.Fig. 4 is for being coated with the signal enlarged drawing of each level of aluminising skin (antirust coat).Among each figure: the 1-cutter hub.The 2-handle of a knife.The 3-matrix steel, folder die cutter mild steel (Fig. 2); Clean steel type cutter medium carbon steel (Fig. 3).The 4-shear steel, the folder die is selected medium carbon steel for use.The 5-antirust coat.6-alfer layer.The rich self-sown layer of 7-, the 8-pellumina.

The utility model is to make like this, is example with the folder die Simple steel rust-resisting cutter that generally uses: the material of cutter hub (1), and matrix steel (3) is selected mild steel for use, and blade (4) is selected medium carbon steel or medium carbon alloy steel for use.Cutter blank is through forge hot or directly make with the clad steel forging rolling by mild steel double team medium carbon steel.Through shaping, moulding, descaling, slightly after throwing and the smart throwing operation, cutter hub must expose the bright and clean surface of low-carbon steel without any dirt lid thing.Obtain to be coated with the aluminising skin by mollerizing or hot-spraying technique immediately.Be coated with ooze material with fine aluminium or aluminium alloy all can, but wherein never allow to contain elements such as harmful Pb, Cr, Cd.Be coated with after oozing cutter hub again through quenching, tempering, leveling, sharpening, have a shave and smart throwing the and make cutter hub.Handle of a knife (2) is many to be made with hard or plastics, riveted or be injection-moulded on the cutter hub (1).Antirust cutter through being up to the standards becomes commodity again through printing, packing.

Can design variety classes as required, different class, the Simple steel rust-resisting cutter series of products of different types and specification.General kitchen knife and hardware machinery product enterprise are all easily implemented the utility model.

Claims (3)

1, a kind of Simple steel rust-resisting kitchen knife is made of cutter hub (1) and handle of a knife (2), and it is characterized in that: the surface in cutter hub (1) has one deck to be coated with the antirust coat (5) of aluminising outer tissue.

2,, it is characterized in that by the described Simple steel rust-resisting kitchen knife of claim 1: the material of cutter hub (1), can select the compound folder steel of mild steel double team medium carbon steel for use, also can select pure intermediate carbon steel sheet for use.

3, according to claim 1,2 described Simple steel rust-resisting kitchen knives, its feature also is: be coated with being coated with of aluminising antirust coat (5) and ooze material, for fine aluminium or be aluminium alloy, but wherein forbidden to contain elements such as harmful Pb, Cr, Cd.
