Abstract
The invention discloses a combined T-shaped knife which is characterized by comprising a knife rod, wherein a slag discharging slot is formed in the knife rod, and a plurality of blades are concentrically arranged at the end part of the knife rod; a plurality of cutting parts are arranged on each blade and comprise front knife surfaces, first rear knife surfaces and second rear knife surfaces which are intersected in sequence; the slag discharging slot keeps extending to the blade at the topmost part from the blade at the bottommost part and is positioned between two corresponding cutting parts; the front knife surfaces are connected with the corresponding wall surface of the slag discharging slot.
Description
Technical field
The present invention 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 processing on eyes frame for inlaying the groove of eyeglass, common T-shaped cutter can only be processed a secondary eyes frame at every turn, working (machining) efficiency is low, and long processing time, thereby for the problems referred to above, the design people has designed the T-shaped cutter of a kind of combination, clamped one time, can to how secondary eyes frame, process simultaneously, thereby greatly improve working (machining) efficiency and precision.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of working (machining) efficiency high, and process time the short T-shaped cutter of combination.
The technical solution adopted for the present invention to solve the technical problems is:
Combine T-shaped cutter, it is characterized in that: comprise knife bar, the end that knife bar is provided with chip area, knife bar is provided with some blades with one heart, each blade is provided with some cutting portions, described cutting portion comprises crossing successively rake face, major first flank, the second rear knife face, described chip area extends to the blade place on top from the blade at the end always, and is positioned between corresponding two cutting portions, and described rake face joins with corresponding chip area wall.
The blade of described top to the blade of the lowermost end angle φ that staggers successively arranges.
The angle ranging from φ=30 °.
Described cutting portion is provided with the 3rd rear knife face intersecting with the second rear knife face, and the 3rd rear knife face joins with corresponding chip area wall.
Described chip area is helical form.
The invention has the beneficial effects as follows: the present invention includes knife bar, the end that knife bar is provided with chip area, knife bar is provided with some blades with one heart, each blade is provided with some cutting portions, described cutting portion comprises crossing successively rake face, major first flank, the second rear knife face, described chip area extends to the blade place on top from the blade at the end always, and be positioned between corresponding two cutting portions, described rake face joins with corresponding chip area wall, by above-mentioned setting, each blade can be processed a secondary corresponding eyes frame, thereby has realized.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic perspective view of the present invention;
Fig. 2 is front schematic view of the present invention;
Fig. 3 is overlooking surface schematic diagram of the present invention.
The specific embodiment
Referring to figs. 1 through Fig. 3, the invention 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 one heart successively three blades 3 from pushing up, on each blade 3, along side edge, be evenly equipped with four cutting portions 4, described cutting portion 4 comprises crossing successively rake face 5, major first flank 6, the second rear knife face 7, described chip area 2 extends to blade 3 places on top from the blade 3 at the end always, and be positioned at 4 of corresponding two cutting portions, described rake face 5 joins with corresponding chip area 2 walls, thereby the iron filings that flow out through rake face 5 are imported into the interior discharge of chip area 2.
As shown in the figure, the blade 3 of top to the blade 3 of the lowermost end angle φ that staggers successively arranges.In this example, angle φ=30 ° of staggering.Above-mentioned setting can guarantee that knife bar 1 is stressed even in working angles, on three blades 3, totally ten two cutting portions 4 evenly separate on perspective plane, avoid cutting portion 4 cutting simultaneously suddenly on different blades 3, cause knife bar 1 stressed too greatly 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 8, the 3rd rear cutter crossing with the second rear knife face 7, the 3rd 8, rear cutter joins with corresponding chip area 2 walls, in said structure, the favourable relief angle from wide-angle of design of a plurality of rear knife faces drops to low-angle relief angle gently continuously, can guarantee that cutter head has enough intensity, can reduce the friction between cutting edge and machined surface again, prevent heating, thereby effectively in improving 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 subject to the extruding force of chip area 2 walls larger, thereby can guide fast iron filings to discharge.
The T-shaped cutter of a kind of combination above embodiment of the present invention being provided, be described in detail, applied specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present invention and core concept thereof; , for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention meanwhile.
