Specific embodiment
It is with reference to the accompanying drawing and real in order to be more clearly understood that the above objects, features, and advantages of the utility model
Example is applied to be described further the utility model.It should be noted that in the absence of conflict, embodiments herein and reality
The feature applied in example can be combined with each other.
Many details are explained in the following description in order to fully understand the utility model, still, this is practical
Novel to be implemented using other modes described herein are different from, therefore, the utility model is not limited to be described below
The limitation of the specific embodiment of specification.
Embodiment 1, as shown in Figure 1 and Figure 2, the present embodiment aim to solve the problem that existing scribing line cutter scribe widths are inconvenient to adjust
And the scribing line rough technical problem in face, for this purpose, a kind of combined type superhard alloy cutter provided in this embodiment, including left
1 and right 2, left 1 and right 2 include tool matrix in the form of annular discs and be arranged in the middle part of tool matrix and be used for fixing cutter
Have the centre bore of matrix, the two sides of centre bore are provided with pin hole, internal screw thread is set in pin hole, it mainly will by bolt tube
It is fixed, and the sawtooth for being separated by setting is evenly arranged on the outer circumference surface of tool matrix, and the above structure is existing common structure,
Therefore in the present embodiment, detailed description is not added, the improved place of the present embodiment emphasis is, also sets between left 1 and right 2
Set ring type filling 3, the whole cylindrical setting of ring type filling 3, be provided on ring type filling 3 matched with centre bore and pin hole it is auxiliary
Centre bore 31 and auxiliary pin hole 32 are helped, in this way, ring type filling 3 is placed on left 1 and the right side when being fixed again by bolt tube
Between piece 2, the spacing for realizing two saw blades increases, and uses since this cutter mainly provides scribing line, in the present embodiment
In, on the basis of 0.5cm, then while selling, can provide 4 ring type fillings, in this way, by way of superposition, and then adjust width.
In order to make section more smooth, in the present embodiment, the sawtooth of left 1 tool matrix 11 is left side tooth 14,
The chamfering degree along 11 rotation direction of tool matrix of three adjacent left side teeth 14 successively increases, and left side tooth 14 is with adjacent three
A to be one group and be circularly set on the outer circumference surface of tool matrix 11, the sawtooth of right 2 tool matrix 21 is right side tooth 24, phase
The chamfering degree along 21 rotation direction of tool matrix of three adjacent right side teeth 24 is successively reduced, and right side tooth 24 is with adjacent three
It is circularly set on the outer circumference surface of tool matrix 21 for one group.In the present embodiment, the chamfering degree of left side tooth 14 be 9 °,
12 ° and 15 °, right side tooth 24 is equally arranged, in this way, the chamfering degree of sawtooth is stepped up, increases the depth of cutting gradually
Add, in this way, the trace cut caused by 9 ° of side teeth will be polished by 12 ° of side teeth, similarly, and the cutting being stepped up in this way
Mode also can be avoided and the phenomenon that chipping, chipping occurs, and set 9 ° for the minimum chamfering degree of side tooth, and mainly it is most
It is first contacted with material, the pressure born is maximum, is conducive to cut for this purpose, setting 9 ° for the minimum chamfering degree of side tooth
It cuts.
In order to ensure stability fixed between left 1, right 2 and ring type filling 3, in the present embodiment, in left 1 He
The groove for placing ring type filling is provided on right 2 tool matrix, the setting of groove is that a part of ring type filling can
It is stuck in groove, it is ensured that the stability of connection.
Herein it should be noted that left 1 and right 2 sawtooth is to be staggered when in use, formed similar existing
Left and right tooth saw blade structure, improve cutting speed.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
