Abstract
The utility model discloses a cutting blade including a disk-shaped metallic matrix having a central hole. A plurality of cutting sawteeth are distributed on the outer periphery of the metallic matrix along a circumferential direction of the metallic matrix uniformly. Chip grooves are arranged among the neighboring cutting sawteeth and ultra-hard grinding material layers are fixed on surfaces of the cutting sawteeth. Each of the cutting sawteeth is provided with two tooth tips departing from each other and extending along the circumferential direction of the metallic matrix respectively. Wear-resisting cutting ring bases are arranged on tooth root parts of the cutting sawteeth on the metallic matrix along the circumferential direction of the metallic matrix. The wear-resisting cutting ring bases and the ultra-hard grinding material layers fixed on the wear-resisting cutting ring base form the wear-resisting cutting rings. By arranging the two tooth tips on each of the cutting sawteeth, the changing period of the cutting blade can be shortened distinctively, the service lifetime of the cutting blade can be prolonged and the working efficiency can be improved.
Description
Technical field
The utility model belongs to the cutting tool technical field, is specifically related to a kind of cutting blade.
Background technology
The cutting blade of existing cutting metal mainly is divided into two types: a kind of cutting blade of emery disc shape, a kind of zigzag cutting blade.For the cutting blade of emery disc form, this cutting blade mainly leans on the frictional force between abrasive particle and workpiece to realize the grinding to workpiece in the course of the work, the cutting blade inefficiency of this emery disc shape, and the heat of generation is big, burn easily workpiece and damage cutting blade.And for the zigzag cutting blade; This cutting blade mainly leans on tangential force and the frictional force between the flank of tooth and workpiece of the rake angle of sawtooth to come cut workpiece in the course of the work; The cutting efficiency of this zigzag cutting skin is high, and caloric value is few, but this zigzag cutting blade only relies on sawtooth to come cut workpiece; Its working life is short, and use cost is higher.And existing zigzag cutting blade generally all is unidirectional tooth cutting blade, and cutting blade is short service time, changes frequent.
The utility model content
The purpose of the utility model is to provide the cutting blade that a kind of cutting efficiency is high, service time is long.
For realizing above-mentioned purpose; The cutting blade that the utility model provided adopts following technical scheme: a kind of cutting blade; Comprise discoid metallic matrix with centre bore, the outer circumference face upper edge metallic matrix of described metallic matrix circumferentially be evenly equipped with a plurality of gulletings, have groove for cuttings between two adjacent gulletings; On the surface of gulleting, be installed with the superhard abrasive bed of material, each gulleting be equipped with two that deviate from mutually, respectively along two crowns of the circumferential extension of metallic matrix; Circumferential arrangement in the tooth root portion of said gulleting along metallic matrix on the described metallic matrix has the wearing-cutting ring base portion, and this wearing-cutting ring base portion constitutes wearing-cutting ring with the superhard abrasive bed of material that is installed on the wearing-cutting ring base portion.
The arc structure transition that is indent between described two crowns connects.
Two crowns on the described gulleting are left crown and right crown, and the height of said left crown all is greater than or less than the height of right crown.
The bottom land of described groove for cuttings is a circular arc.
The bottom land of described at least one groove for cuttings has the radiating groove that radially extends and run through described wearing-cutting ring.
The abrasive grain of the superhard abrasive bed of material on described wearing-cutting ring and the gulleting is between 20 orders-120 order.
The beneficial effect of the utility model is: during cutting blade cut workpiece that the utility model provided; At first by the gulleting grinding work piece and on workpiece cut; And then by the wearing-cutting ring engaging friction stage to the cut that rubs of the cut-out section on the workpiece; So both can promote gulleting and continue cutting, also prevent the generation of intermediate plate phenomenon simultaneously.And two crowns on gulleting can clockwise rotate cutting blade earlier, as the cutting crown workpiece are carried out cutting processing by a crown so earlier; By the time after this crown lost efficacy, backward rotation was changeed cutting blade again, brought into play dissection by the another one crown as the cutting crown; Completion is to the cutting of workpiece; Can significantly shorten the replacement cycle of cutting blade like this, prolong the service life of cutting blade, increase work efficiency.In addition, the groove for cuttings that between two gulletings, leaves on the cutting blade that the utility model provided can be dispelled the heat in chip removal, when wet cutting, can increase the contact area of cutting blade and cooling water equally, plays better thermolysis.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of cutting blade of providing of the utility model.
The specific embodiment
As shown in Figure 1; A kind of embodiment of cutting blade; Cutting blade among this embodiment comprises the discoid metallic matrix 2 with centre bore 1, in the outer circumference face upper edge of metallic matrix 2 metallic matrix circumferentially be evenly equipped with a plurality of gulletings 3,3 adjacent of two gulletings have groove for cuttings 4; The bottom land of described groove for cuttings 4 is a circular arc; On the surface of gulleting 3, be installed with the superhard abrasive bed of material, each gulleting 3 be equipped with two that deviate from mutually, respectively along two crowns of the circumferential extension of metallic matrix, the arc structure transition that is indent between two crowns connects.Two crowns on the gulleting 3 are left crown 31 and right crown 32, and the height of the left crown 31 in the present embodiment is all greater than the height of right crown 32.Circumferential arrangement in the tooth root portion of said gulleting 3 along metallic matrix on the described metallic matrix 2 has the wearing-cutting ring base portion, and this wearing-cutting ring base portion constitutes wearing-cutting ring 5 with the superhard abrasive bed of material that is installed on the wearing-cutting ring base portion.
Of Fig. 1, the bottom land of 9 groove for cuttings that whole groove for cuttings interval distributes has the radiating groove that radially extends and run through described wearing-cutting ring.Certainly, in other embodiments, can radially extend and run through the radiating groove of described wearing-cutting ring in the bottom land setting of at least one groove for cuttings.
In the above-described embodiments, the number of gulleting is 18, and in other embodiments, the number of gulleting can be 15-28.
In the above-described embodiments, the height of the left crown on all gulletings is all greater than the height of right crown, like this when using at the beginning; Drive cutting blade earlier and turn clockwise, by left crown performance dissection, when left crown lost efficacy; Again with the cutting blade counter-rotating, by right crown performance dissection.Certainly, in other embodiments, the height that also can make left crown on all gulletings is all less than the height of right crown; Like this, when using at the beginning, drive cutting blade earlier and be rotated counterclockwise; Earlier by right crown performance dissection; When right crown lost efficacy, again with the cutting blade counter-rotating, by left crown performance dissection.
Abrasive material on the superhard abrasive bed of material on described wearing-cutting ring and the gulleting is diamond abrasive or CBN abrasive material or the two compound abrasive, and the granularity of the abrasive material on the superhard abrasive bed of material is between 20 orders-120 order.
In the foregoing description, the arcuate structure transition by indent between two crowns of gulleting connects, and does not adopt acute angle to connect, and has avoided heat and stress between the acute angle connection to concentrate.The arc structure of indent between two crowns here can serve as the chip removal radiating groove, and when wet cutting, can increase the contact area of cutting blade and cooling water, plays better thermolysis.
