Abstract
The invention discloses a convex trilateral drill blade with corrugated cutting edges and a high boss. The convex trilateral drill blade comprises a blade body, the high boss and a positioning surface, wherein the outer edges of the blade body are designed with cutting edges, the points of the cutting edges are corrugated edges, the high boss is positioned on the upper part of the blade body, the positioning surface is positioned in the center of the blade body, and the middle part of the positioning surface is designed with a screw hole. The points of the cutting edges of the blade are designed into the corrugated edges, thus, the contact area of scrap iron and the front angle surface of the blade is reduced, and wear and tear is reduced; meanwhile, the boss is heightened, scraps are easy to roll and break by the blade, furthermore, the scrap breaking effect is good, and wear and tear of a machined surface caused by the scrap iron in the cutting process is reduced. In addition, the blade adopts mechanically-clamped and indexable methods, three cutting edges are provided, the blade is convenient to change, and the cutting edges of the blade are convenient to change.
Description
Technical field
The present invention relates to a kind of machine clip variable-position drill blade, particularly a kind of protruding three limit drill blades that have ripple cutting edge and high boss.
Background technology
Current most protruding three limit drill blade chip curling grooves have the forms such as bipolar low boss chip curling groove, the low boss chip curling groove of point type.The drill blade of bipolar chip curling groove, because the contact area of blade cutting edge and iron filings is large, blade abrasion is serious, and boss is low, and iron filings are frangibility not, causes cutter hub serious wear because iron filings are long, and it is not fine making work piece surface smoothness yet.The drill blade of the low boss chip curling groove of point type, what adopt is point type chip curling groove, and this kind of chip curling groove reduced to have reduced comparatively speaking with the contact-making surface of iron filings the wearing and tearing of blade, but due to the low boss that is still adopting, chip breaking effect increases, but volume bits chip breaking effect is not still very desirable.
Summary of the invention
In order to address the above problem, the present invention has designed a kind of protruding three limit drill blades with ripple cutting edge and high boss, comprise blade body, blade body outer rim is divided and is designed with cutting edge, and the cutting edge of this cutting edge is wave edge, wherein, also comprise high boss, be positioned at blade body top, also comprise locating surface, be positioned at the center of blade body, this locating surface middle part is designed with screw hole.
Preferably, described blade body adopts be can machine clip variable-position mode.
Preferably, described cutting edge has three groups, and is evenly distributed on blade body outer rim.
Preferably, in described three groups of cutting edges, the angle of every group is 84 °
Preferably, the distribution shape of described high boss and the distribution of cutting edge are corresponding.
Beneficial effect of the present invention is that blade cutting edge is designed to the contact area that wave edge has reduced iron filings and the front edged surface of blade, reduces wear, increased boss simultaneously, make blade easily roll up bits chip breaking, and then chip breaking is effective, has reduced the wearing and tearing of iron filings and machined surface in working angles.In addition, blade adopts be can machine clip variable-position mode, have three groups of cutting edges, facilitate the replacing of blade and the replacing of blade cut sword.
Accompanying drawing explanation
Fig. 1 is the upward view in the specific embodiment of the invention with the protruding three limit drill blades of ripple cutting edge and high boss.
Fig. 2 is the front view in the specific embodiment of the invention with the protruding three limit drill blades of ripple cutting edge and high boss.
Below in conjunction with Fig. 1, Fig. 2, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Fig. 1 is the upward view with the protruding three limit drill blades of ripple cutting edge and high boss of the present invention, mainly comprises blade body 1, cutting edge 2, ripple sword 3, high boss 4, locating surface 5 and screw hole 6.On cutting edge 2, be designed with ripple sword 3, the design of ripple sword 3 can reduce the contact area of iron filings and blade body 1 front edged surface in working angles, reduce wear, in blade body 1, be designed with high boss 4 simultaneously, high boss 4 can make blade easily roll up bits chip breaking, and chip breaking is effective, the wearing and tearing of iron filings and machined surface in working angles have been reduced.In blade body 1, be designed with locating surface 5 and screw hole 6, can blade body 1 is fixing, and can be convenient for changing blade and three groups of cutting edges.
