Abstract
The utility model relates to a computerized knife for carving characters. The utility model is composed of a knife head and a knife body which are combined into an integral structure; the front part of the knife body is a cylinder and the tail part of the knife body is a cone. The front side of the knife head is a conical surface; the front angle of the knife head adopts negative rake angle, so the knife of the utility model can slickly and contradictorily unify sharpness and durability during work, in order to be both sharp and durable. The utility model is an ideal cutting tool for cutting Chinese and English characters and pictures.
Description
The utility model is the cutting tool of Chinese and English picture and text cutting machine.
The front that the cutter head of the present domestic U.S.'s computer lettering cutter cutter that uses adopts also comprises zero degree as the angle of plane anterior angle as positive rake angle.So this cutter is to be had relatively high expectations in this selection of material of cutter aspect in the mill because of the weak of point of a knife partial design, it requires to select for use wearability good, the high-test metal cutter material that intensity is good.Otherwise will directly influence the service life of cutter in cutting work.
The purpose of this utility model provides a kind of improved cutter, and it can strengthen the intensity of point of a knife effectively, thereby even uses prevailing Hardmetal materials also can make cutter reach higher durability in cutting work in the cutter manufacturing.
The purpose of this utility model is to realize like this; Partly adopting its anterior angle of front of taper seat type to adopt negative value at cutter head is negative rake.
The utility model is owing to increased the thickness of point of a knife in the anterior angle employing negative rake of cutter head part, strengthened the intensity of point of a knife effectively and sharpness that the front really adopts taper seat can increase cutter makes this cutter dexterously sharpness and durability realized that in cutting work unity of contradictions promptly accomplishes not only sharp but also durable, can manufacture the computer lettering cutter of each geomery specification with this structure, carry out cutting work with the Chinese and English picture and text cutting machine that is applicable to all size model.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Accompanying drawing is a kind of overview of computer lettering cutter, 1--cutter head among the figure, 2--cutter hub.
