Abstract
The utility model belongs to the field of cutting tools, and particularly relates to a dedicated stainless steel countersink used for chamfering of stainless steel orifices. The countersink comprises a knife handle connected with a cutting power device, and is characterized in that the front end of the knife handle is connected with a connecting rod; a chamfering part is arranged on one end of the connecting rod, and comprises an end part cutting face arranged on the end part; cutting edges are symmetrically arranged between the end part cutting face and the connecting rod; the included angle between the symmetrically-arranged cutting edges is 90 degrees; and a chip discharging groove is arranged in the chamfering part, and extends to the connecting rod. The countersink is high in processing precision and surface smoothness.
Description
Technical field
The utility model belongs to cutting tool field, particularly a kind of stainless steel Special chamfer cutter for stainless steel orifice chamfer.
Background technology
Along with the development of economic society, the continuous lifting of productivity, people have also proposed more and more higher requirement to the material of product, and now increasing product adopts stainless steel as material.
Adopt stainless steel as producing material, this has just proposed new requirement to cutting tool, traditional cutter cannot meet the requirement of stainless steel material processing, existing chamfer machining adopts general fluted drill to process, precision and the fineness of processing all do not reach requirement like this, in order to meet the requirement of quality of product, therefore need to improve the structure of cutter.
Utility model content
The utility model is for the deficiencies in the prior art, and the utility model has designed a kind of good processing accuracy, the stainless steel Special chamfer cutter that surface smoothness is good.
The utility model is achieved through the following technical solutions:
Stainless steel Special chamfer cutter, comprise the handle of a knife being connected with cutting power set, it is characterized in that: the front end of described handle of a knife is connected with connecting rod, one end of connecting rod is provided with chamfered section, chamfered section comprises the cutting face, end that is positioned at end, symmetrically arranged cutting edge between cutting face, end and connecting rod, and the angle of described symmetrically arranged cutting edge is 90 °, in described chamfered section, be provided with chip area, chip area extends on connecting rod.
Between described connecting rod and handle of a knife, be provided with the portion of stepping down, the described portion of stepping down is the conical surface.
The diameter in described cutting face, end is 0.1mm.
The utlity model has a little following:
1, the utility model has designed a kind of special rose reamer, has overcome low precision and the poor requirement of fineness of the carrying out processing existence of traditional employing fluted drill;
2, the cutting face of end of the present utility model adopts planar design, is convenient to carry out the centering of cutter, is conducive to improve the positioning precision between cutter and workpiece.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the utility model is aforesaid will be become apparent with other object, feature and advantage.Wherein:
Figure 1 shows that structural representation of the present utility model;
In figure, 1 is cutting face, end, and 2 is cutting edge, and 3 is connecting rod, and 4 is the portion of stepping down, and 5 is handle of a knife.
The specific embodiment
The utility model is achieved through the following technical solutions:
Stainless steel Special chamfer cutter as shown in Figure 1, comprise the handle of a knife 5 being connected with cutting power set, it is characterized in that: the front end of described handle of a knife 5 is connected with connecting rod 3, one end of connecting rod 3 is provided with chamfered section, chamfered section comprises the cutting face, end 1 that is positioned at end, symmetrically arranged cutting edge 2 between cutting face, end 1 and connecting rod 3, and the angle of described symmetrically arranged cutting edge 2 is 90 °, in described chamfered section, be provided with chip area, chip area extends on connecting rod 3.
Between described connecting rod 3 and handle of a knife 5, be provided with the portion of stepping down 4, the described portion that steps down 4 is the conical surface.
The diameter in described cutting face, end is 0.1mm.
The utlity model has a little following:
1, the utility model has designed a kind of special rose reamer, has overcome low precision and the poor requirement of fineness of the carrying out processing existence of traditional employing fluted drill;
2, the cutting face of end of the present utility model adopts planar design, is convenient to carry out the centering of cutter, is conducive to improve the positioning precision between cutter and workpiece.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model openly in scope; still can do some corrections or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
