The beneficial effects of the utility model are: the utility model 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 and rake face intersect, and the intersection of described plane and rake face forms the main cutting edge of cutter, and this intersection is a straight line, the arc surface on described plane and cutter neck surface intersects, and this arc surface and rake face intersect the front cutting edge that the circular arc line forming forms 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, 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 utility model is further illustrated.
Fig. 1 is overview of the present utility model;
Fig. 2 is the overview of the utility model other direction;
Fig. 3 is schematic top plan view of the present utility model;
Fig. 4 is the enlarged diagram of tool bit part.
The specific embodiment
Referring to figs. 1 through Fig. 3, the utility model 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 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 a plane 7, this plane 7 intersects 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 and one intersects with respect to plane 7 and the arc surface of cutter neck concave surface, this arc surface radius is 0.5mm, and this arc surface and rake face 6 intersect the front cutting edge 9 that the circular arc line forming forms 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 when 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 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 plane 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.
