Abstract
The utility model discloses a composite steel kitchen knife, which resolves the problem that the existing kitchen knife is short in service life and the edge of the kitchen knife is easy to be turned. The composite steel kitchen knife comprises a knife body and a knife edge, the lower end surface of the knife body is fixedly connected with the upper end surface of the knife edge via a fixing layer, and the knife edge is made of high-speed steel. According to the above structure, stainless steel is organically combined with the high-speed steel, the high-speed steel has extremely good hardenability, the knife edge made of the high-speed steel has the advantages of good hardness and excellent abrasive resistance, the knife body is not easy to rust and easy for processing, and an cutting edge of the knife edge is sharp and durable.
Description
Technical field
The utility model relates to a kind of kitchen knife.
Background technology
The kitchen knife that uses of people has a variety ofly in daily life, and system cutter factory is when making kitchen knife, and all steel have two big classes, the one, martensitic stain less steel, the 2nd, high-carbon steel.Above-mentioned two kinds of steel all need quenching process.During quenching, for trying to achieve higher martensitic structure.System cutter factory in the quenching technical process, employing be the surface hardening technology.Method in common is that the surface with cutter reaches hardening heat fast and inserts in the water at the blade that surface sprinkling or fast again short-term training will reach hardening heat, or takes out rapidly in the oil, and is named and is underwater sound quench method.Be used for making the cutting edge of tool surface and blade to have high hardness, can guarantee the toughness and the plasticity of cutter inside again.Make the unlikely micro-flaw of cutter and cause waste product.So produced kitchen knife of system cutter technology, in use, after repeatedly whetting a knife, after the rigid high hard formation of that layer was worn away on kitchen knife skin table and its cutting edge, the sharpness of kitchen knife cutting edge will be faded.Continue to use again, will often go out blunt sword, turned phenomenon, need the constant cutting edge that sharpens a kitchen knife.Until kitchen knife is discarded.This system cutter technology is a kind of great waste to the energy of China's worsening shortages.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is to provide a kind of simple in structure, nonabradable clad steel kitchen knife of kitchen knife cutting edge.
For achieving the above object, clad steel kitchen knife of the present utility model comprises blade part and knife edge part, wherein, is fixed together by affixed layer between the upper surface of described blade part lower surface and knife edge part; Wherein, described knife edge part is that high-speed steel is made.
Wherein, described blade partly adopts stainless steel to make.
Wherein, be provided with connection bump in described blade part lower surface, correspondence is provided with the connection groove in the upper surface of described knife edge part, and the connection bump of described blade part is arranged in the connection groove of knife edge part.
Wherein, be provided with the connection groove in described blade part lower surface, correspondence is provided with connection bump in the upper surface of described knife edge part, and described knife edge part connection bump is arranged in the connection groove of blade part.
Wherein, the cross section of described connection groove is the V font, and described connection bump cross section is and is connected the corresponding V font of groove.
Wherein, the aspect ratio of described blade part and knife edge part is 7: 3.
In the said structure, stainless steel and high-speed steel are combined, because high-speed steel quenching degree is fabulous, the knife edge part made from it has the advantages that hardness is good, wearability is good, the blade that had both guaranteed so partly is difficult for getting rusty and easy and processing, has guaranteed that again the cutting edge of blade is sharp durable.

Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 shows structural representation for embodiment illustrated in fig. 1 cuing open.
Fig. 3 shows structural representation for cuing open of another embodiment.
Fig. 4 is the structural representation of the utility model the 3rd embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figures 1 to 4, clad steel kitchen knife of the present utility model comprises blade part 1 and knife edge part 2, wherein, is fixed together by affixed layer 3 between the upper surface of described blade part lower surface and knife edge part; Wherein, described knife edge part is that high-speed steel is made, and after knife edge part adopted high-speed steel, it had higher hardness, and is therefore wear-resistant, and comparatively sharp behind the mill.
Above-mentioned blade part can adopt other metal material, preferably adopts stainless steel to make.Be convenient to processing like this, and be difficult for getting rusty.Above-mentioned affixed layer 3 can adopt scolders such as silver soldering solder, welding wire by welding blade part 1 and knife edge part 2 to be fixed together.Certainly, if possible, also can adopt bonding agent bonding.
Be provided with connection bump in described blade part lower surface, correspondence is provided with the connection groove in the upper surface of described knife edge part, and the connection bump of described blade part is arranged in the connection groove of knife edge part.Opposite, also can be provided with the connection groove in described blade part lower surface, correspondence is provided with connection bump in the upper surface of described knife edge part, and described knife edge part connection bump is arranged in the connection groove of blade part.
As shown in Figures 2 and 3, the cross section of above-mentioned connection groove and connection bump cross section are the V font.Certainly, the cross section of above-mentioned connection groove and connection bump cross section can also be rectangle, circle or swallow-tail form etc., as long as what be convenient to links together blade part and knife edge part, but this connection bump be connected the length direction that groove all is arranged on cutter on, and as a kind of distortion of the present utility model, can also be as shown in Figure 4, with connection bump be connected the width that groove is arranged on cutter on.
More than; it only is preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
