The invention has the beneficial effects as follows: the invention discloses a kind of mould square 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 a plane, this plane is crossing with rake face, and the intersection of described plane and rake face forms the main cutting edge of cutter, and this intersection is a straight line, described plane is crossing with the arc surface on cutter neck surface, and this arc surface circular arc line of forming crossing with rake face forms the front cutting edge of cutter, and main cutting edge and front cutting edge junction form a wedge angle, in said structure, main cutting edge and front cutting edge can time processing go out the surface that two geomeries differ, one-shot forming, avoid the error that in repeatedly processing, bring die change position, ensure the precision of working position, and processing (100 left and right of processing in general one day) fast, qualification rate is high.
Brief description of the drawings
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 tool bit part.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, the invention discloses a kind of mould square 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 entirety roughly become L shape, cutter head 2 is provided with a location basal plane 5, in the time of 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 a plane 7, this plane 7 is crossing with rake face 6, and the intersection of described plane 7 and rake face 6 forms the main cutting edge 8 of cutter, and this intersection is a straight line, described plane 7 is crossing with the arc surface of cutter neck concave surface with respect to plane 7 with one, this arc surface radius is 0.5mm, and this arc surface circular arc line of forming crossing with rake face 6 forms the front cutting edge 9 of cutter, and main cutting edge 8 forms a wedge angle 16 with front cutting edge 9 junctions, this structure can be poured out circular arc at the sidewall of rising as high as the banks in the time rising as high as the banks to mould milling, and this circular arc is discrete with the bottom surface of rising as high as the banks.
As shown in the figure, cutter head 2 is provided with knife face 10 after the first neck, and described rake face 6 is crossing with knife face 10 after this first neck, and described cutter head 2 is provided with knife face 11 after the second neck, and after described the first neck, knife face 10 is crossing with knife face 11 after this second neck; Described cutter mouth 4 is provided with knife face 12 behind the first top, and described plane 7 is crossing with knife face 12 behind this first top, and described cutter head 2 is provided with knife face 13 behind the second top, and behind described the first top, knife face 12 is crossing with knife face 13 behind this second top.The design of said structure, can ensure that cutter head 2 has enough intensity, can avoid again the friction between other cutter head 2 parts and the machined surface except main cutting edge 8, 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 not be detained, thereby discharge easily, ensured that chip removal is unobstructed.
