The specific embodiment
Referring to figs. 1 through Fig. 4, the utility model 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.
