Abstract
The utility model discloses a composite blade including a cutting edge made of a first material and a cutter body made of a second material, wherein the cutting edge is fixedly connected with the cutter body, the first material is different from the second material, and the cutting edge is provided with a connecting portion which is inserted and fixed in the cutter body. The cutting edge of the composite blade is made of tool steel or ceramics, and the edge is sharp, thereby satisfying use requirement. The cutter body is made of plastic or other metal materials, which facilitates installation, and boring and tapping on the cutter body, reduces labor intensity and improves work efficiency. The use requirement of the cutting edge is ensured, and the use amount of tool steel or ceramic is greatly reduced. The production cost is reduced. The cutting edge and the cutter body are firmly jointed and are not likely to be disengaged. The blade combines the advantages of two materials. Moreover, the composite blade is reasonable in structure, reliable in use, simple in process, convenient for manufacture and use, and low in cost.
Description
Technical field
The utility model relates to a kind of cutter, relates in particular to a kind of blade that is composited by two or more different materials.
Background technology
Common blade is processed by homogenous material, and like steel knife, Stupalox etc., the edge of a knife is sharp, is easy to cutting.But all steel blade adopts high carbon tool steel or alloy tool steel manufacturing usually, has increased the consumption of tool steel on the one hand, has improved cost, and on the other hand, after the tool steel Quenching Treatment, boring, tapping be difficulty very, has increased working strength of workers, and work efficiency is low.And ceramic tip is to use the high technology ceramics HTHP to fire to form, have wear-resisting, hardness is high, can not get rusty, advantage such as cleaning easily, full ceramic tip not only cost high, cost an arm and a leg, and toughness is lower, property is crisp easily broken.
The utility model content
The utility model is exactly for the problem that solves above-mentioned prior art existence a kind of composite blade to be provided, and when guaranteeing edge of a knife instructions for use, reduces cost, improves working (machining) efficiency.
The purpose of the utility model realizes through following technical scheme:
A kind of composite blade comprises the blade of first material and the cutter hub of second material, and said blade is fixedly connected with cutter hub.
Preferably, connecting portion being set on the said blade inserts and is fixed in the cutter hub.
Preferably, on the said connecting portion at least one through hole is set.
Preferably, said blade is bar shaped.
Preferably, said blade is connected through the injection mo(u)lding one with cutter hub.
Preferably, said blade is fixedly connected through bonding forming with cutter hub.
Preferably, said blade is fixedly connected through welding fabrication with cutter hub.
Preferably, said blade and cutter hub are through the mode firm engagement of mechanical clamping.
Preferably, said blade and cutter hub are through the mode firm engagement of hot pressed sintering.
Preferably, said first material is different from second material, and first material is metal, pottery or other conventional tool founding materialses, and second material is plastics or other metals that are different from first material.
Compared with prior art, the utlity model has following beneficial effect:
The composite blade of the utility model, blade is tool steel or pottery etc., and the edge of a knife is sharp, satisfies instructions for use, and cutter hub is plastics or other metal materials, makes on cutter hub boring, tapping all more easy, easy for installation, reduces labour intensity, improves work efficiency.
The utility model is when guaranteeing edge of a knife instructions for use; Reduce the use amount of tool steel or pottery significantly; Reduced production cost; Blade engages with cutter hub firmly, difficult drop-off, thereby synthesis reveals the advantage of two kinds of materials on same blade, and have rational in infrastructure, use reliable, technology is simple, make easy to use, low cost and other advantages.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the decomposing schematic representation of Fig. 1;
Fig. 3 is the profile of cutter hub.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Be depicted as the preferred embodiment of the utility model like Fig. 1,2, a kind of composite blade comprises the blade 1 of first material and the cutter hub 2 of second material, and blade 1 is fixedly connected with cutter hub 2.First material of blade 1 is different from second material of cutter hub 2, and first material of blade 1 is preferably metal, pottery or other traditional tools founding materialses, and second material of cutter hub 2 is preferably plastics or is different from other metals of first material.The composite blade of present embodiment is elaborated with metal blade 1 and plastics cutter hub 2.
Preferably, in concrete embodiment, blade also can be fixedly connected through bonding forming with cutter hub, or is fixedly connected through welding fabrication, or the mode firm engagement through mechanical clamping, or passes through mode firm engagement of hot pressed sintering or the like.
The composite blade of the utility model, blade is tool steel or pottery etc., and the edge of a knife is sharp, satisfies instructions for use, and cutter hub is plastics or other metal materials, makes on cutter hub boring, tapping all more easy, easy for installation, reduces labour intensity, improves work efficiency.
The utility model is when guaranteeing edge of a knife instructions for use; Reduce the use amount of tool steel or pottery significantly; Reduced production cost; Blade engages with cutter hub firmly, difficult drop-off, thereby synthesis reveals the advantage of two kinds of materials on same blade, and have rational in infrastructure, use reliable, technology is simple, make easy to use, low cost and other advantages.
More than the disclosed several specific embodiments that are merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
