Abstract
The combined blade for cylindrical hob of paper shredder consists of one ring blade with cutting edge and one base plastic ring for the ring blade to be embedded on. The base plastic ring has polygonal axle hole fitting the shaft rod. The cylindrical hob of shredder in the combined structure has reasonable structure, low steel consumption, reduced weight, less material consumption and capacity of raising the cutting efficiency of the paper shredder.
Description
Technical field
What the present invention relates to is cutter for paper grinder, especially a kind of combined blade for cylindrical hob of shredder.
Technical background
As everyone knows, existing cutter for paper grinder is to be made of a pair of cylindrical shape hobboing cutter that rotates on the 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 shown in Figure 1, and the periphery of blade is provided with the sword that blocks that stretches out outside most, and blade center is provided with the axle center hole that can cooperate with the polygon axostylus axostyle.It is made by the disposable stamping-out of hardware stamping technology by the steel plate greater than blade usually.This blade is diameter no matter, must produce with independent steelplate punching respectively, and not only the steel materials are many for they, and make the cylindrical shape hobboing cutter after the assembling heavier usually.
Summary of the invention
The objective of the invention is deficiency, a kind of blade material that makes full use of is provided, and can reduces the combined blade for cylindrical hob of shredder of blade weight at above-mentioned global formation structure blade existence.
Combined blade for cylindrical hob of shredder of the present invention is characterized in that: described blade is by being provided with the blade ring that blocks sword and forming with the chimeric plastic base ring of blade ring inner ring; The plastic base ring center is provided with the axle center hole that can cooperate with the polygon axostylus axostyle.
Described blade ring inner ring is evenly equipped with the protruding nail that can embed the plastic base ring periphery; The plastic base ring periphery is evenly equipped with and the corresponding pit of the protruding nail of blade ring inner ring.
Described plastic base ring casting is planted within the blade ring and is enclosed.
Combined blade for cylindrical hob of shredder design principle of the present invention is: the plastic base ring made from light material substitutes the blade part of blade, it neither can influence original cut paper function of blade, also can reduce the consumption of steel, reduce the monomer weight of blade, and then reduce the overall weight of the cylindrical shape hobboing cutter after the assembling.
Combined blade for cylindrical hob of shredder design science of the present invention, rational in infrastructure.It not only can reduce razor steel material use quantity and monomer weight, also can utilize a kind of waste material of big specification blade to produce at least a small dimension blade, promptly in the big blade operation of stamping-out, directly obtain small blade, it not only makes steel be fully utilized, save material, and can improve the stamping-out efficient of blade greatly.
The concrete structure of combined blade for cylindrical hob of shredder of the present invention is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of combined blade for cylindrical hob of shredder;
Fig. 2 is a combined blade for cylindrical hob of shredder decomposition texture schematic diagram shown in Figure 1;
Fig. 3 is the schematic diagram of blade ring and the shared block plate of small dimension blade.
The specific embodiment
Embodiment: can be clear that from Fig. 1 and Fig. 2 combined blade for cylindrical hob of shredder is by being provided with the blade ring 1 that blocks sword 11 and forming with the chimeric plastic base ring 2 of blade ring 1 inner ring; Described blade ring 1 inner ring is evenly equipped with the protruding nail 12 that can embed plastic base ring 2 peripheries; Described plastic base ring 2 centers are provided with the axle center hole 21 that can cooperate with the polygon axostylus axostyle, and plastic base ring 2 peripheries are evenly equipped with and the protruding nail 12 corresponding pits 22 of blade ring 1 inner ring.Described plastic base ring 2 castings are planted circle within blade ring 1.The protruding nail 12 of blade ring 1 inner ring cooperates with plastic base ring 2 all edge pits 22, can guarantee can not take place radially between the two or axial moving.
Described plastic base ring 2 one sides are connected with and are used for break bar packing ring 23 at interval.Space washer independently when this packing ring 23 can replace existing shredder cylindrical shape hobboing cutter assembling has reduced assembly process.
Described plastic base ring 2 castings are planted circle within blade ring 1.
This combining structure single blade is installed identical with the mounting means of existing monomer structure blade on shredder cylindrical shape hobboing cutter.
This combining structure single blade can make full use of the blade material, promptly produces the small dimension blade in the big specification blade ring 1 of stamping-out, and as shown in Figure 3, the dead meal behind blade ring 1 stamping-out of this combining structure single blade just in time is the monomer blade 3 of an existing structure.
Above content is in conjunction with concrete preferred implementation, to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.Without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by claims of being submitted to.
Claims (6)
1, a kind of combined blade for cylindrical hob of shredder is characterized in that: described blade is by being provided with the blade ring that blocks sword and forming with the chimeric plastic base ring of blade ring inner ring; The plastic base ring center is provided with the axle center hole that can cooperate with the polygon axostylus axostyle.
