Abstract
The utility model discloses the T-shaped cutter of a kind of combination, it is characterized in that: comprise knife bar, knife bar is provided with chip area, the end of knife bar is provided with some blades with one heart, each blade is provided with some cutting portions, described cutting portion comprises the rake face, major first flank, the second rear knife face that intersect successively, described chip area extends to the blade place of pushing up most from the blade at the most end always, and is positioned between corresponding two cutting portions, and described rake face connects with corresponding chip area wall.
Description
Technical field
The utility model relates to a kind of process tool, particularly the T-shaped cutter of a kind of combination.
Background technology
T-shaped cutter is used for the groove inlaying eyeglass for processing on eyes frame, common T-shaped cutter can only process a secondary eyes frame at every turn, working (machining) efficiency is low, and long processing time, thus for the problems referred to above, the design people devises the T-shaped cutter of a kind of combination, clamped one time, can process how secondary eyes frame simultaneously, thus substantially increase working (machining) efficiency and precision.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of working (machining) efficiency high, and the T-shaped cutter of combination that process time is short.
The utility model solves the technical scheme that its technical problem adopts:
Combine T-shaped cutter, it is characterized in that: comprise knife bar, knife bar is provided with chip area, the end of knife bar is provided with some blades with one heart, each blade is provided with some cutting portions, described cutting portion comprises the rake face, major first flank, the second rear knife face that intersect successively, described chip area extends to the blade place of pushing up most from the blade at the most end always, and is positioned between corresponding two cutting portions, and described rake face connects with corresponding chip area wall.
The blade of described top to lowermost end blade successively offset angular φ arrange.
The angle ranging from, φ=30 °.
Described cutting portion is provided with the three rear knife face crossing with knife face after second, and after the 3rd, knife face connects with corresponding chip area wall.
Described chip area is helical form.
The beneficial effects of the utility model are: the utility model comprises knife bar, knife bar is provided with chip area, the end of knife bar is provided with some blades with one heart, each blade is provided with some cutting portions, described cutting portion comprises the rake face, major first flank, the second rear knife face that intersect successively, described chip area extends to the blade place of pushing up most from the blade at the most end always, and be positioned between corresponding two cutting portions, described rake face connects with corresponding chip area wall, by above-mentioned setting, each blade can be processed a secondary corresponding eyes frame, thus achieves.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is front schematic view of the present utility model;
Fig. 3 is overlooking surface schematic diagram of the present utility model.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model discloses the T-shaped cutter of a kind of combination, comprise cylinder shape knife rod 1, knife bar 1 is provided with chip area 2, the end of knife bar 1 is provided with three blades 3 successively with one heart from pushing up, along side along being evenly equipped with four cutting portions 4 on each blade 3, described cutting portion 4 comprises the rake face 5 intersected successively, major first flank 6, knife face 7 after second, described chip area 2 extends to blade 3 place of pushing up most from the blade 3 at the most end always, and be positioned between corresponding two cutting portions 4, described rake face 5 connects with corresponding chip area 2 wall, thus the iron filings flowed out through rake face 5 are imported in chip area 2 and discharge.
As shown in the figure, the blade 3 of blade 3 to the lowermost end of top successively offset angular φ arrange.In this example, angle φ=30 ° of staggering.Above-mentioned setting can ensure knife bar 1 uniform force in working angles, on three blades 3, totally ten two cutting portions 4 evenly separate on the projection surface, avoid the cutting portion 4 on different blade 3 to cut suddenly simultaneously, cause knife bar 1 stressed too large too anxious, cause knife bar 1 stress fatigue and reduction of service life, increase machine burden.
As shown in the figure, cutting portion 4 is provided with the three rear cutter 8 crossing with knife face 7 after second, after 3rd, 8, cutter connects with corresponding chip area 2 wall, in said structure, the favourable relief angle from wide-angle of design of continuous multiple rear knife face drops to low-angle relief angle gently, can ensure that cutter head has enough intensity, can reduce again the friction between cutting edge and machined surface, prevent heating, thus effectively in raising cutting precision.
Described chip area 2 is helical form, and it is large that spiral helicine chip area 2 not only holds bits amount, and in the process of cutter rotation, iron filings are comparatively large by the extruding force of chip area 2 wall, thus can iron filings be guided fast to discharge.
The one provided the utility model embodiment above combines T-shaped cutter, be described in detail, apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
Claims (5)
