Described cutter head is provided with knife face behind the second top, and behind described the first top, behind knife face and this second top, knife face intersects.
Knife face and the angle [alpha] of locating basal plane formation, 90 ° of < α <98 ° behind described the first top.
The angle beta that behind described the second top, knife face and location basal plane form, 15 ° of < β <25 °.
Described knife bar and cutter neck intersection all adopt arc transition.
The plane at described main cutting edge place and knife bar central axis distance are h, 0<h<0.02mm.
The invention has the beneficial effects as follows: the invention discloses a kind of mould circular groove milling cutter, comprise cylinder shape knife rod and cutter head, described cutter head comprises cutter neck and cutter mouth, cutter head is provided with a location basal plane, cutter mouth is provided with rake face, the end of cutter mouth is provided with an arc surface, this arc surface intersects with location basal plane and rake face, and the intersection of described arc surface and rake face forms the main cutting edge of cutter, and this intersection is a circular arc line, the position that described arc surface and cutter neck surface join is by a transition arc transition with respect to arc surface and cutter neck concave surface, and this transition arc intersects with location basal plane the front cutting edge that the circular arc line forming forms cutter, in said structure, main cutting edge and front cutting edge can time processing go out two discontinuous arc surfaces, one-shot forming, avoided the error that in repeatedly processing, bring die change position, guarantee the precision of working position, and processing (is processed 100 left and right for general one day) fast, qualification rate is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is overview of the present invention;
Fig. 2 is the overview of other direction of the present invention;
Fig. 3 is schematic top plan view of the present invention.
Fig. 4 is the enlarged diagram of cutter head.
The specific embodiment
Referring to figs. 1 through Fig. 4, the invention discloses a kind of mould circular groove milling cutter, comprise cylinder shape knife rod 1 and cutter head 2, described cutter head 2 comprises cutter neck 3 and cutter mouth 4, cutter neck 3 and cutter mouth 4 integral body roughly become L shape, cutter head 2 is provided with a location basal plane 5, when the fixture of Cutting tool installation manner in plant equipment, the fixed cutting tool by pin dieback location basal plane 5, prevent that cutter from rotating relative to fixture, cutter mouth 4 is provided with rake face 6, the end of cutter mouth 4 is provided with an arc surface 7, this arc surface 7 intersects with rake face 6, and the intersection of described arc surface 7 and rake face 6 forms the main cutting edge 8 of cutter, and this intersection is a circular arc line, described arc surface 7 passes through a transition arc transition with cutter neck concave surface with respect to arc surface 7 with the position that cutter neck surface joins, this transition arc radius is 0.5mm, and this transition arc and rake face 6 intersect the front cutting edge 9 that the circular arc line forming forms cutter, this structure not only can be poured out circular arc when giving mould groove milling, and avoid forming stress at arc surface 7 with joint, cutter neck surface and concentrate.
As shown in the figure, cutter head 2 is provided with knife face 10 after the first neck, and after described rake face 6 and this first neck, knife face 10 intersects, and described cutter head 2 is provided with knife face 11 after the second neck, and after described the first neck, after knife face 10 and this second neck, knife face 11 intersects; Described cutter mouth 4 is provided with knife face 12 behind the first top, and behind described arc surface 7 and this first top, knife face 12 is crossing, and described cutter head 2 is provided with knife face 13 behind the second top, and described the first rear knife face 12 in top intersects with the rear knife face 13 in this second top.The design of said structure, can guarantee that cutter head 2 has enough intensity, can avoid again other cutter head 2 parts except main cutting edge 8 and the friction between machined surface, prevent heating, and in cutter rotary course, the knife face of above-mentioned inclination can have certain extruding force to smear metal, and smear metal can be detained, thereby discharge easily, guaranteed that chip removal is unobstructed.
And, further design, the angle [alpha] that behind the first top, knife face 12 and location basal plane 5 form, 90 ° of < α <98 °; The angle beta that behind described the second top, knife face 13 and location basal plane 5 form, 15 ° of < β <25 °, the design of above-mentioned angle can be played chip removal effect well, does not affect again the rigidity of cutter head 2.
The radius r of described arc surface 7,0.4mm<3<0.5mm, groove width to be processed in this size and mould adapts.
As further preferred structure, knife bar 1 all adopts arc transition with cutter neck 3 intersections, guarantees the rigidity of knife bar 1 and cutter neck junction; The plane at described main cutting edge 8 places and knife bar 1 central axis distance are h, and 0mm<h<0.02mm, guarantees cutting edge roundness cutting force towards processed products.
Milling cutter of the present invention is that wolfram steel or tool steel material are made.According to the characteristic of machined material, can also carry out vacuum plating (as nitrogenize is admired or nitrogen calorize is admired etc.), the service life of further improving cutter to cutter.
A kind of mould circular groove the milling cutter 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.
