Abstract
A kind of thin slot knife of high-strength diamond, it is related to annular groove machining tool field, including alloy cutter hub and diamond blade, the side of alloy cutter hub is equipped with positioning groove, alloy cutter hub is made of scalpel body and support cutter hub, the width of support cutter hub is less than scalpel body width, protrusion is set to the front end of scalpel body, the upper side of cutter hub is supported to be less than scalpel body upper side, on the upside of scalpel body front end and equipped with the blade erecting bed being generally aligned in the same plane with support cutter hub upper side, the diamond blade is in type shape, and diamond blade is mounted on the upside of support cutter hub and on erecting bed.The utility model has cutting endurance big, effectively stablizes blade, avoids coming off for blade in cutting；The advantages that cutter hub intensity and rigidity height, high precision machining, service life is long.
Description
Technical field
The present invention relates to annular groove machining tool fields, and it is that a kind of cutting endurance is big to elaborate, and effectively stablizes blade, avoids
Blade comes off in cutting；Cutter hub intensity and rigidity height, high precision machining, the thin slot knife of high-strength diamond of service life length.
Background technology
It is known that slot knife easily can output one or more groove in interior outer tube wall, the difference for meeting user will
It asks.But at present, on the certain types of automobile engine, piston seal slot often designs very narrow, only 1mm or so, minimum
Only 0.7mm, and the percent ripple requirement of annular groove side wall is very high, and surface roughness value is very low.For these narrow annular grooves, groove width is determined
Determined the width of cutting edge, it is existing for process the thin slot knife of this narrow annular groove its in cutting edge with it is wide narrow before and after knife bar
Strip.The integral strength of this thin slot knife of strip is low, and during tool sharpening, knife bar cross-sectional direction cuts when being ground side edge
Shear force is easily broken knife bar, in working angles, cross shear can be generated when lathe and actual cut environmental degradation, due to knife
Piece and cutter hub connection area is narrow causes blade obscission, knife bar intensity is weaker, easily causes knife, vibration or breaking phenomenon.
Invention content
Present invention aim to address above-mentioned the deficiencies in the prior art, provide a kind of cutting endurance greatly, effectively stablize knife
Piece avoids blade in cutting from coming off；Cutter hub intensity and rigidity height, high precision machining, the high-strength diamond of service life length
Thin slot knife.
Technical solution is used by the present invention solves above-mentioned the deficiencies in the prior art：
A kind of thin slot knife of high-strength diamond, including alloy cutter hub and diamond blade, the side of alloy cutter hub, which is equipped with, determines
Position groove, it is characterised in that alloy cutter hub by scalpel body and support cutter hub form, support cutter hub width be less than scalpel body width,
Protrusion is set to the front end of scalpel body, supports the upper side of cutter hub less than scalpel body upper side, on the upside of scalpel body front end and sets
There is the blade erecting bed being generally aligned in the same plane with support cutter hub upper side, the diamond blade is in type shape, diamond tool
Piece is mounted on the upside of support cutter hub and on erecting bed.
The width of heretofore described scalpel body is 2 mm -5mm, and the diamond blade in type shape is by preceding
The blade cut sword of side and the blade connecting seat composition of rear side, the width of blade cut sword is no more than 1mm, the width of blade connecting seat
It spends of same size with scalpel body.
The material of heretofore described diamond blade is composite polycrystal-diamond；The material of the alloy cutter hub is
Sintered powder.
Invention increases the connection area of diamond blade and alloy cutter hub, the cutting for improving diamond blade is born
Power performance effectively stablizes blade, and blade in cutting is avoided to come off.Meanwhile such overall structure can also enhance diamond
The integral strength and rigidity of thin slot knife improve machining accuracy, improve the service life of thin slot knife.
Description of the drawings
Fig. 1 is the dimensional structure diagram of the present invention.
Specific embodiment
The thin slot knife of high-strength diamond as shown in Figure 1, including alloy cutter hub and diamond blade, diamond blade is with closing
By Welding together, alloy cutter hub is made of golden cutter hub scalpel body 5 and support cutter hub 4, and the width of support cutter hub 4 is less than
The width of scalpel body, the width of scalpel body is 4mm, and support cutter hub 4 protrudes the front end for being set to scalpel body, scalpel body 5 and support
Cutter hub 4 is made into integration, and the section of alloy cutter hub front end supports the upper side of cutter hub to be less than the upside of scalpel body 5 in convex shape
Face 3, scalpel body front end upside are equipped with the blade erecting bed being generally aligned in the same plane with support 4 upper side of cutter hub, the diamond
Blade is in type shape, in the diamond blade of type shape by the blade cut sword 1 of front side and 2 groups of the blade connecting seat of rear side
Into since cutting edge has relief angle, for the width of cutting edge slightly larger than the width of support cutter hub, the width of blade cut sword 1 is support
1.1-1.2 times of 4 width of cutter hub, the width of blade cut sword are not more than 1mm, the width of blade connecting seat and the width of scalpel body
It is all mutually 4mm.Diamond blade is mounted on the upside of support cutter hub and on erecting bed；After installation, diamond blade upper side and master
Cutter hub upper side is generally aligned in the same plane.Between the diamond tool bit end sword and side edge and support between cutter hub and scalpel body all
It is connected with circular shape transition, enhances cutting hardness and cutter hub service life.The side of scalpel body 5 is equipped with determines with what lathe was bonded
Position groove 6；The material of the diamond blade is composite polycrystal-diamond；The material of the alloy cutter hub is powder sintered
Body.
Invention increases the connection area of diamond blade and alloy cutter hub, the cutting for improving diamond blade is born
Power performance effectively stablizes blade, and blade in cutting is avoided to come off.Meanwhile such overall structure can also enhance diamond
The integral strength and rigidity of thin slot knife improve machining accuracy, improve the service life of thin slot knife.
