Abstract
The utility model relates to a milling cutting blade with combined cutting blades which comprises a main body with an installation hole. The main body comprises a first cutting face and a second cutting face, wherein the first cutting face is the front face, and the second cutting face is the back face. The first cutting face and the second cutting face are all provided with four corresponding unit sections, wherein the side faces of each unit section are sequential provided with a main cutting edge, a cutting point edge, an auxiliary cutting edge, a cutting point back face, a second back cutting face, a main cutting face and an auxiliary cutting face. The adjacent unit sections are symmetry arranged by the center axial line of the main body, and the separated unit sections are symmetry arranged by the axial core line of the installation hole of the main body. The cutting point back face is vertical arranged to the center axial line of the main body. The cutting tool with the structure has the function of cutting over the center with a negative rake, the cutting point uses two negative back cutting faces, thereby the ability of the main cutting edge is projected, further with the combination of a small back angle, the intensity of the cutting tool is better. The cutting tool cuts over the center, the cutting force on the cutting blade changes from small to big, then from big to small, thereby the situation that the crash of the big cutting force formed by the beginning of the contact leads to the breakage of the cutting blades is reduced.
Description
Technical field
The utility model relates to a kind of milling cutting insert with combination cutting face that is installed on the coned cutter, is used for processing ball-type track on surface of the work.
Background technology
Milling cutting insert on the existing milling cutter is formed with plane bottom side and plane side surface, the bottom side of this milling cutting insert is pressed against planar base in the blade pedestal, side surface is pressed against on the supporting side wall in the blade pedestal, so blade is fixed in the blade pedestal, it at work can be with suitable cutting speed work with suitable velocity of rotation rotary cutter.But the cutting force that acts on the blade can't be according to the needs of processing work, for example cutting force is ascending descending again, it is by stable cutting force, can't overcome blade and just begin the impact of the big cutting force that contacts and caused milling cutting insert fracture damage problem.U.S. Pat 6102630 has disclosed a kind of milling cutting insert, has the joint face of a back shape in its bottom side, and this joint face is used for cooperating with a similar joint face on the instrument, but the major cutting edge of its blade partly is a linearity.It can't overcome that blade has just begun the impact of the big cutting force that contacts and the defective that causes milling cutting insert fracture damage.
Summary of the invention
Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of main cutting edge ability that highlights is provided, in conjunction with little relief angle, make cutter intensity better have the combination cutting face milling cutting insert.It can realize that the cutting force on the blade is ascending, and is descending again, reduces impact that blade just begun the big cutting force that contacts and causes the effect of rupturing.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the milling cutting insert with combination cutting face, include the body of an installing hole, body has first knife face and second knife face at preceding each other or the end, and the technical measures of taking comprise: dividing equally on first knife face and the second knife face face has four corresponding cellular zones; Wherein any cellular zone side all is shaped on knife face behind the main cutting edge, point of a knife cutting edge, front cutting edge, point of a knife of arrangement, the second back knife face, main back knife face, minor flank; And, between the adjacent cellular zone with body centerline axis symmetry, between the cellular zone separately with body installing hole shaft core line symmetry; Knife face and body center line are perpendicular behind the point of a knife.
