By using the indexable groove milling blade, not only is the whole strength of a cutter enhanced, but also a tipping phenomenon can be effectively avoided, the service life of the cutter is greatly prolonged, the processing efficiency of a workpiece is ensured, the cost is reduced, and the service life of the cutter is over 6 times as long as that of the traditional cutter.
Description
Technical field
The utility model relates to a kind of groove milling blade, and especially a kind of indexable dish type groove milling blade for the milling groove belongs to the metal cutting tool technical field.
Background technology
At interval a plurality of groove milling blades are installed on the dish type grooving cutter cutterhead circumference, by rotatablely moving of dish type grooving cutter cutterhead, drive groove milling blade is finished the Milling Process to groove on the workpiece.Existing groove milling blade anterior angle is big, cutter intensity is low, main cutting edge both sides point of a knife cutting state is the some cutting, add the shock loading in the working angles, make groove milling blade main cutting edge that the tipping phenomenon take place in working angles easily, cutter life is short, has influenced the working (machining) efficiency of workpiece greatly, the maintenance cost height.
The patent No. is the Indexable cutting inserts that 200680033825.7 utility model patent discloses a kind of milling cutter, milling cutter body and has been shaped as truncated pyramid, wherein Indexable cutting inserts has end face and the basic bottom surface parallel with end face, main cutting edge extends from end face to the bottom surface direction, rake face is connected with main cutting edge, and leading to the bottom surface, front cutting edge is limited by the rake face that is associated and end face intersection.This Indexable cutting inserts can be than the right-angled corner in the full depth processing work, but it still fails to solve the problem of the easy tipping of milling cutter.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, intensity is high, the tipping phenomenon be difficult for to take place, cutter life long indexable groove milling blade.
The utility model is achieved by the following technical programs:
A kind of indexable groove milling blade, described indexable groove milling blade is the regular polygon laminated structure, comprise two regular polygon supporting surfaces that are parallel to each other and a plurality of sides that are connected two regular polygon supporting surfaces, a plurality of sides are intersected many main cutting edges perpendicular to described regular polygon supporting surface of formation in twos, many front cutting edges of formation are intersected with two regular polygon supporting surfaces respectively in both sides, a plurality of side, side, every main cutting edge front side is provided with the arc chip area that links to each other with rake face, sharpening goes out the back knife face that band is born relief angle α on every main cutting edge rear side side, every main cutting edge is by the negative chamfered edge of arc and described back knife face rounding off, and described rake face both sides sharpening respectively go out symmetrical arc chamfered edge.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid indexable groove milling blade, wherein said negative relief angle α are 1 °～2 °.
Aforesaid indexable groove milling blade, the negative chamfered edge arc of radius r1 of wherein said arc is 0.2mm～0.5mm.
Aforesaid indexable groove milling blade, the angle β of wherein said arc chamfered edge and regular polygon supporting surface are 15 °～17 °, and arc chamfered edge width a is 0.1mm～0.3mm, and arc chamfered edge length h is 1/5～2/5 of regular polygon supporting surface length of side L.
Aforesaid indexable groove milling blade, the degree of depth b of wherein said arc chip area are 0.02～0.03 of regular polygon supporting surface length of side L.
The anterior angle of the utility model cutter is less, back knife face adopts less negative relief angle, the cutting state of main cutting edge both sides point of a knife becomes the face cutting by original some cutting simultaneously, simple in structure, not only improve the bulk strength of cutter, and can also effectively prevent the generation of tipping phenomenon, prolonged the service life of cutter greatly, guaranteed the working (machining) efficiency of workpiece, reduced cost, cutter life is than improving more than 5 times originally.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
