Abstract
The utility model discloses a tungsten steel alloy paper separating knife, which comprises a structure main body, wherein the structure main body is composed of an inner knife disc, an outer knife disc and a knife edge from the center to the edge in sequence, and the thickness of the structure main body is gradually thinned from the center to the edge; the utility model is of an integrated structure, simple structure, and convenient for mass production and transportation; the tungsten steel alloy is formed by adopting a powder metallurgy heat treatment mode, and the wear resistance is high; the main structure body is gradually thinned from the center to the edge, and the included angle of the cutting edge is set to 40 degrees, so that the working efficiency is improved while the sharpness of the cutting edge is ensured, the use of raw materials is reduced, and the production cost is reduced.
Description
Technical Field
The utility model relates to a divide paper equipment technical field, concretely relates to tungsten steel alloy to divide paper sword.
Background
At present, the corrugated paper that exists in the market divides paper blade, high-speed steel to divide paper blade including tungsten steel, this kind of blade is because whole tungsten steel and high-speed steel of adopting for the cost is higher, and because tungsten steel and high-speed steel are relatively poor with the wearability of alloy, consequently change the number of times and also compare and increase moreover, thereby increased user's cost, the work efficiency who also reduces simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a tungsten steel alloy paper separating knife in order to solve the problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose, a tungsten steel alloy divides paper sword, including a main structure body, main structure body comprises interior blade disc, outer blade disc and cutting edge by center to the edge in proper order, just main structure body's thickness is by center to the edge attenuation gradually.
Preferably, the center of the inner cutter disc is provided with a cutter shaft hole which is of a circular structure.
Preferably, a plurality of through holes with circular structures are uniformly arranged on the inner cutter head.
Preferably, the structural body is of an integral structure.
Preferably, the thickness of the inner cutter head is larger than that of the outer cutter head, and the thickness of the cutter head is larger than that of the cutting edge.
Preferably, the included angle of the blade edge may range between 35 and 45 degrees.
The utility model has the advantages that: the utility model is of an integrated structure, simple structure, and convenient for mass production and transportation; the tungsten steel alloy is formed by adopting a powder metallurgy heat treatment mode, and the wear resistance is high; the main structure body is gradually thinned from the center to the edge, and the included angle of the cutting edge is set to 40 degrees, so that the working efficiency is improved while the sharpness of the cutting edge is ensured, the use of raw materials is reduced, and the production cost is reduced.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a cross-sectional view of the present invention;
in the figure: 1. an inner cutter head; 2. a cutter shaft hole; 3. a through hole; 4. an outer cutter head; 5. a blade.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a tungsten steel alloy paper separating cutter comprises a structural body, wherein the structural body is composed of an inner cutter disc 1, an outer cutter disc 4 and a cutting edge 5 from the center to the edge in sequence, and the thickness of the structural body is gradually thinned from the center to the edge.
Wherein, interior blade disc 1 center is equipped with cutter shaft hole 2, cutter shaft hole 2 is circular structure, evenly be equipped with the through-hole 3 of a plurality of circular structures on the interior blade disc 1, main structure formula structure as an organic whole, the thickness of interior blade disc 1 is greater than the thickness of outer blade disc 4, the thickness of blade disc 4 is greater than the thickness of cutting edge 5, the contained angle scope of cutting edge 5 can be between 30-50 degrees, and wherein, the best contained angle is 40 degrees.
The structural body is formed from a tungsten steel alloy by powder metallurgy heat treatment.
The tungsten steel alloy paper separating integrated structure has simple structure and is convenient for mass production and transportation; the tungsten steel alloy is formed by adopting a powder metallurgy heat treatment mode, and the wear resistance is high; the main structure body is gradually thinned from the center to the edge, and the included angle of the cutting edge is set to 40 degrees, so that the working efficiency is improved while the sharpness of the cutting edge is ensured, the use of raw materials is reduced, and the production cost is reduced.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
