Abstract
A lightening cutting blade of a kneader cylindrical hob cutting comprises a cutting body with an evagination projecting cutting point, wherein the cutting body is arranged on the peripheral surface of the cylindrical hob cutting, and an axial center hole is arranged in the middle of the cutting body and is engaged with a shaft lever, characterized in that the cutting body is combined with a cutting point intensifying layer. The design principle is that the material thickness of the body of the cutting blade is reduced and the thickness and the intensity of the cutting point paper are satisfied by the combined layer. The cutting blade applied in the kneader has the same guillotine effect with similar products. As the utility model makes the thickness of the cutting blade greatly reduced compared with the same standard cutting body, the steel products usage and the monomeric weight of the cutting blade greatly reduced and the material cost reduced. Also as the monomeric weight of the cutting blade is greatly reduced, thereby reducing the set weight of the kneader and the power takeoff of the driven motor of the kneader and realizing the purpose of energy-saving.
Description
Technical field
The utility model relates to kneader bar, especially a kind of light blades of cylindrical hobbing cutter for paper crusher.
Background technology
As everyone knows, existing cutter for paper grinder is to be made of a pair of cylindrical shape hobboing cutter that rotates in rightabout.And the cylindrical shape hobboing cutter is separated with the break bar of pad between being placed on the axostylus axostyle by axostylus axostyle and most and assembles, described break bar then by and two auxiliary-blades that are close together constitute.Existing blade is an all steel matter blade as depicted in figs. 1 and 2, and the periphery of blade is provided with most the outer points of a knife that stretch out, and blade center is provided with the axle center hole that can cooperate with the polygon axostylus axostyle.The cooperation appropriateness at point of a knife position when satisfying rightabout two cylindrical shape hobboing cutter cut papers.The blade periphery stretches out outward block sword usually must the certain thickness of tool, be the requirement of the point of a knife thickness that satisfies blade, existing blade is made by the disposable stamping-out of hardware stamping technology by the steel plate that waits greater than the blade external diameter usually.The blade of this blade and point of a knife uniform thickness, not only the steel materials are many, and make the cylindrical shape hobboing cutter after the assembling heavier usually.
Summary of the invention
The purpose of this utility model is the deficiency that exists at above-mentioned uniform thickness blade, provides a kind of and both can guarantee that blade carried the paper effect, can reduce again blade with material thickness, reduce the light blades of cylindrical hobbing cutter for paper crusher of blade weight.
The utility model light blades of cylindrical hobbing cutter for paper crusher comprises: periphery is provided with the cutter hub of the outer point of a knife that stretches out, and the cutter hub center is provided with the axle center hole that can cooperate with axostylus axostyle, it is characterized in that: the point of a knife position of described cutter hub is compounded with the point of a knife enhancement Layer.
The thickness of described point of a knife enhancement Layer is identical with cutter hub thickness.
Described point of a knife enhancement Layer is by being reserved in cutter hub point of a knife side, forming with the sheet material bending fold of cutter hub uniform thickness.
The design principle of the utility model light blades of cylindrical hobbing cutter for paper crusher is: reduce blade the blade part use material thickness, satisfy required thickness of point of a knife cut paper and intensity with composite bed.It neither can influence the original cut paper function of blade, and can reduce the consumption of steel, reduces the monomer weight of blade, and then reduces the overall weight of the cylindrical shape hobboing cutter after the assembling.
The utility model light blades of cylindrical hobbing cutter for paper crusher design science, rational in infrastructure.The cut paper effect that this blade is used on shredder is identical with like product.Reduce because the technical program is compared greatly blade thickness with the same specification cutter hub, it can significantly reduce razor steel material use quantity and monomer weight, has saved material.The minimizing of blade monomer weight can make that the cylindrical shape hobboing cutter weight after the assembling descends, and it not only can make shredder complete machine weight reduce, and can subtract the power output that reduces the shredder CD-ROM drive motor, reaches energy-conservation purpose.
The concrete structure of the utility model light blades of cylindrical hobbing cutter for paper crusher is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of existing shredder cylindrical shape hobboing cutter blade;
Fig. 2 is an existing shredder cylindrical shape hobboing cutter blade left view shown in Figure 1;
Fig. 3 is the structural representation of light blades of cylindrical hobbing cutter for paper crusher;
Fig. 4 is a light blades of cylindrical hobbing cutter for paper crusher left view shown in Figure 3;
Fig. 5 is the break bar structural representation that light blades shown in Figure 3 is formed.
The specific embodiment
Embodiment: form from the point of a knife enhancement Layer 13 that Fig. 3 and Fig. 4 can be clear that the cutter hub 11 of the point of a knife 12 that light blades of cylindrical hobbing cutter for paper crusher 1 stretches out outside being provided with by periphery and be compounded in the point of a knife position of cutter hub.Described cutter hub 11 centers are provided with the axle center hole 14 that can cooperate with axostylus axostyle.
The thickness of described point of a knife enhancement Layer 13 is identical with the thickness of cutter hub 11.
Described point of a knife enhancement Layer 13 by be reserved in cutter hub 11 point of a knife sides, with the sheet material bending fold of cutter hub 11 uniform thickness and flatten and form.
For improving the blade intensity of the utility model light blades 1, the blade position of described cutter hub 11 is provided with concavo-convex ring-type strengthening groove 15,16.
The break bar that the utility model light blades is formed as shown in Figure 5, break bar is made up of two light blades 1 and 1 '.Two light blades 1 are corresponding with 1 ' structure, and two point of a knife positions of the break bar that combines cooperate proper, are equal to existing same specification cutter hub.
Above content is the detailed description of the utility model being done in conjunction with a concrete preferred implementation, can not assert that structural design of the present utility model is confined to these explanations.Engineers and technicians for technical field under this without departing from the inventive concept of the premise, can also make some changes and improvements, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
