Description
Technical field
The utility model belongs to processing cutting tool technical field, specifically a kind of forming cutter structure.
Background technology
When processing dimension small cross sections is the groove of bottleneck shape, existing processing mode first adopts boring cutter to bore the larger notch of bottom size, then milling cutter is just adopted to be processed by notch less for top, so just, need to change process tool, reduce working (machining) efficiency, and need tool setting again, reduce machining accuracy.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of reasonable in design, is convenient to processing, ensures the forming cutter structure of working (machining) efficiency and precision.
The utility model provides following technical scheme:
A kind of forming cutter structure, comprise handle of a knife and the cutting portion being arranged at handle of a knife one end, described cutting portion comprises the cutting tip being fixed at handle of a knife end face, the thickness of cutting tip is 0.6mm-1mm, the processing diameter that cutting tip outer peripheral face is formed is less than the diameter of handle of a knife, the cutting edge of cutting tip comprises the first straight sword be on the most front outer peripheral face of cutting tip, the the first oblique sword be connected with the first straight sword upper end, and the second straight sword to be connected with the first oblique sword, described first straight sword, second straight sword is consistent with the axis direction of handle of a knife, first oblique sword and handle of a knife axis direction form included angle A, included angle A is 40 °-50 °.
Have employed technique scheme, in process, first straight sword carries out processing and forming to the notch of large-size bottom workpiece, and the notch of the second straight sword to workpiece top reduced size carries out processing and forming, and the first oblique sword is processed for the joint face between bottom plate rabbet, upper notch; The utility model can process at one time the notch of different size, without the need to changing cutter, ensureing working (machining) efficiency, and can not produce processing accumulated error, guaranteeing machining accuracy.
Further, the upper end of the described second straight sword is 1.4mm-1.6mm to the distance d between the first straight sword lower end.
Further, the described first straight sword, the thickness of the first oblique sword, the second straight sword is equal with the thickness of cutting tip.
Further, the two sides of described cutting tip are provided with the first straight sword, the first oblique sword, the second straight sword respectively, and two group of first straight sword, two group of first oblique sword, two group of second straight sword form bottleneck shape.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
See Fig. 1-4, a kind of forming cutter structure, comprise handle of a knife 1 and the cutting portion being arranged at handle of a knife one end, cutting portion comprises the cutting tip 2 being fixed at handle of a knife end face, the thickness of cutting tip is 0.6mm-1mm, the processing diameter that cutting tip outer peripheral face is formed is less than the diameter of handle of a knife, the cutting edge of cutting tip comprises the first straight sword 3 be on the most front outer peripheral face of cutting tip, the the first oblique sword 4 be connected with the first straight sword upper end, and the second straight sword 5 to be connected with the first oblique sword, first straight sword, second straight sword is consistent with the axis direction of handle of a knife, first oblique sword and handle of a knife axis direction form included angle A, included angle A is 40 ° or 45 ° or 50 °.
The upper end of the second straight sword is 1.4mm or 1.5mm or 1.6mm to the distance d between the first straight sword lower end.The thickness of the first straight sword, the first oblique sword, the second straight sword is equal with the thickness of cutting tip.The two sides of cutting tip are provided with the first straight sword, the first oblique sword, the second straight sword respectively, and two group of first straight sword, two group of first oblique sword, two group of second straight sword form bottleneck shape.
Process of the present utility model: in process, the notch 7 of the first straight sword to large-size bottom workpiece 6 carries out processing and forming, the notch 8 of the second straight sword to workpiece top reduced size carries out processing and forming, and the first oblique sword is processed for the joint face 9 between bottom plate rabbet, upper notch.
In concrete enforcement, the processing and forming of more multi-work piece is applicable in order to promote forming cutter, handle of a knife is also provided with two-stage process blade, it comprises the second oblique sword 10 that sword straight with second is connected, the 3rd straight sword 11 be connected with the second oblique sword, and the 3rd oblique sword 12 to be connected with the 3rd straight sword, the angle C that second oblique sword and handle of a knife axis direction are formed is 20 ° or 25 ° or 30 °, the angle D that 3rd oblique sword and handle of a knife axis direction are formed is 20 °-30 °, in concrete enforcement, angle C and angle D can arrange equal; The diameter of handle of a knife is between 4mm-6mm, and the diameter at the 3rd straight sword place is less than the diameter of handle of a knife; Second oblique sword is identical with the incline direction of the 3rd oblique sword, and the incline direction of the first oblique sword is contrary with the direction of the second oblique sword, the 3rd oblique sword.In addition, in concrete enforcement, the two sides 13 of cutting tip can be arranged to the concave face to cutting tip body recess, be convenient to the chip removal in process like this.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
