Abstract
The utility model discloses a disc cutting blade, which comprises a disc-shaped metal body with a centre hole. The outer circumference of the metal body is fixedly provided with a plurality of cutting sawteeth around the metal body. The thickness of the tooth backs of the cutting sawteeth is larger than the thickness of the tooth tips of the cutting sawteeth. The cutting sawteeth are evenly distributed along the outer circumference of the metal body. A chip groove is formed between every two adjacent cutting sawteeth respectively. An abrasion-resistant cutting layer is uniformly welded on the surfaces of the cutting sawteeth. Since the disc cutting blade is provided with cutting sawteeth, the cutting efficiency of the disc cutting blade is effectively improved. Meanwhile, the abrasion-resistant cutting layer is welded on the surfaces of the cutting sawteeth. Thus, on the premise that the cutting efficiency is ensured, the service life of the cutting sawteeth is effectively prolonged. The disc cutting blade has the advantages of high cutting efficiency, long service life and convenient machining and manufacturing.
Description
Technical field
The utility model belongs to the cutter technical field, is specifically related to a kind of disk cutting blade.
Background technology
The cutting blade of existing cutting metal is the disk cutting blade; As disclosing a kind of disk cutting blade in the Chinese utility model patent specification of CN201941091U at Granted publication number; This cutting blade comprises the discoid metallic matrix with centre bore; Circumferential periphery at metallic matrix is provided with wear-resisting incised layer around said metallic matrix; Foreign aid's periphery of metallic matrix is provided with groove, and to even distribution, link to each other forms the cutter head of cutting blade to this groove between two grooves along the excircle of metallic matrix.Groove part on this cutting blade is arranged on the wear-resisting incised layer as the work zone, has increased the contact-making surface of cutting blade and cooling water, has improved cooling effect, has reduced the wear rate of cutting blade.But the cutting efficiency of this disk cutting blade is lower, and particularly when cutting hardness during than higher steel, its cutting efficiency is lower.
The utility model content
The purpose of the utility model is to provide a kind of disk cutting blade, with the lower technical problem of cutting efficiency that solves disk cutting blade of the prior art.
For realizing above-mentioned purpose; The disk cutting blade that the utility model provided adopts following technical scheme: a kind of disk cutting blade; Comprise discoid metallic matrix with centre bore; The circumferential periphery of said metallic matrix is installed with a plurality of gulletings around said metallic matrix, and the thickness of the back of tooth of gulleting is greater than the thickness of crown, and the excircle of the said metallic matrix in said gulleting edge is to even distribution; Between two adjacent two gulletings, form chip area, evenly be welded with wear-resisting incised layer on described gulleting surface.
Described surface soldered has the thickness of gulleting of wear-resisting incised layer greater than the thickness of metallic matrix.
Excircle along said metallic matrix makes progress, and the tooth root width of described gulleting is greater than the width of tooth top.
Described metallic matrix thickness radially increases from inside to outside gradually.
The cut surface of described gulleting is the arc of indent.The beneficial effect of the utility model: the circumferential periphery of the discoid metallic matrix of the disk cutting blade that the utility model provided is provided with a plurality of gulletings; These gulletings to being uniformly distributed with, form chip area along the excircle of metallic matrix between two adjacent gulletings, this disk cutting blade has adopted gulleting; The thickness of the back of tooth of gulleting is greater than the thickness of crown; Can prevent crown because of intensity difference occurring wear phenomenon, improve service life, and can effectively improve the cutting efficiency of disk cutting blade; Simultaneously; In the gulleting surface soldered wear-resisting incised layer is arranged, can under the prerequisite that guarantees cutting efficiency, effectively prolong the service life of gulleting like this.The disk cutting blade cutting efficiency that the utility model provided is high, long service life, convenient processing and manufacture.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of disk cutting blade of providing of the utility model;
Fig. 2 is the structural representation of the sawtooth on the cutting blade among Fig. 1;
Fig. 3 is the left view of Fig. 2.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of embodiment of disk cutting blade, the disk cutting blade among this embodiment comprises the discoid metallic matrix 2 with centre bore 1, metallic matrix thickness radially increases from inside to outside gradually; For improving the cutting efficiency of cutting blade; The circumferential periphery of metallic matrix 2 is installed with a plurality of gulletings 3 around said metallic matrix, and the thickness of the back of tooth of gulleting is greater than the thickness of crown, and the cut surface of this gulleting 3 is the arc of indent; Excircle along said metallic matrix makes progress; The tooth root width of described gulleting 3 is greater than the width of tooth top, and the excircle of the said metallic matrix in said gulleting edge forms chip area 4 to being uniformly distributed with between two adjacent gulletings.For guaranteeing the service life of cutting blade, evenly be welded with wear-resisting incised layer 31 on the surface of described gulleting 3, the surface soldered here has the thickness of the gulleting of wear-resisting incised layer to be larger than the thickness of metallic matrix.
In the foregoing description, wear-resisting incised layer is the cubic boron nitride superhard abrasive material, and this superhard abrasive bed of material is welded on the surface of gulleting uniformly through cemented carbide powder, and the granularity of abrasive material is between 20-120 orders.In other embodiments, also can select for use to the higher abrasive material of other hardness in the prior art and replace cbn layer.
In the foregoing description; Form chip area between two adjacent gulletings, the shape of gulleting can reduce the contact area with material to be processed, when cutting blade is worked; A large amount of metal fillings are discharged from chip area; The frictional heating phenomenon is obviously reduced, so promptly reduced the burn of workpiece, prolong the life-span of cutting blade again.
The disk cutting blade that is provided in the foregoing description is not only applicable to the workpiece that cutting hardness is little, grade of steel is low, and simultaneously, because in the surface soldered of gulleting wear-resisting incised layer is arranged, above-mentioned disk cutting blade also is applicable to big, the firm high workpiece of cutting hardness.
In the foregoing description, the metallic matrix thickness that cutting blade adopts radially increases from inside to outside gradually, has effectively prevented the intermediate plate phenomenon in cutting process.
In the foregoing description, the number of teeth of gulleting can not too much can not be very few, and the number of teeth is very few; Cutting ability will descend, and the number of teeth is too much, and gulleting will be overstocked, though excellent cutting performance; But the quantitative change of the appearance of between cog bits is little, causes the sawtooth heating easily, so space width is located between the 5-25mm.The number of teeth of gulleting is between 10-50.The sawtooth anterior angle is between 5 °-25 °, between 10 °-20 ° of the relief angle values.
