Description
Technical field
The utility model relates to engraving technology fields, specifically, being related to a kind of graver.
Background technique
Digital-controlled carving machine has faster speed and higher precision compared to hand engraving, and can be difficult in hand engraving
It is carved on the material of the high rigidity of progress, is widely used at present.The digital-controlled carving machine of the prior art generallys use wolfram steel material
The Hardness loss of the graver of matter, wolfram steel cutter under the high temperature conditions is small, therefore can adapt to high-revolving engraving occasion, still
Its hardness is general, and engraving process abrasion is larger, and point of a knife is not sharp, and easily crumble high brittle material to be processed, sharp if holding
And mill is carried out to graver and is repaired, the outer dimension of graver can be made to change, graver is caused also to be needed in a pre-installation to knife,
It is time-consuming and laborious.
Utility model content
The purpose of this utility model is to provide a kind of graver, engraving process abrasion is small, and point of a knife can keep cutting edge of a knife or a sword for a long time
Benefit.
Technical solution used by graver disclosed by the utility model is:
A kind of graver, the cutter head including knife handle and set on knife handle one end, the cutter head include a supporting surface, protrude from this
The boss of supporting surface and blade set on supporting surface；The blade is that polycrystalline diamond is made, and the blade, which is divided into, to be fixed on
The bonding pad of boss and the point of a knife area for stretching out boss, the bonding pad includes adjacent bottom surface and one side, and the bottom surface is supported
Lean on and be fixed on supporting surface, the side against and be fixed on boss；Wherein, the side is equipped with a taper platform outstanding,
The taper platform is harmonious with the groove for being opened in boss.
Preferably, the boss includes opposite lower surface and upper surface, between the upper surface and lower surface
Equipped with a tapered surface and a vertical plane, the vertical plane be one perpendicular to supporting surface isosceles trapezoid, the side of the bonding pad
It is resisted against the vertical plane.
Preferably, the side of the bonding pad is in a rectangular trapezoid.
Preferably, the side of the bonding pad is in isosceles triangle.
Preferably, the blade is fixed on boss and supporting surface by vacuum brazing, and the solder of soldering is copper pricker
Welding powder.
Preferably, the supporting surface is recessed to form an evacuation area far from boss side.
The beneficial effect of graver disclosed by the utility model is: blade uses polycrystalline diamond, and hardness is high, processing abrasion
Small, point of a knife can keep for a long time sharp, and engraving hard stone material will not crumble sculptured surface because of the brittleness of stone material, improve graver
Service life.By the way that taper platform is arranged in side, groove is opened up on boss, taper platform is harmonious with groove so that blade is determined
Position is reliable, and taper platform can be used as the stability that force transmission element improves blade when engraving.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model graver.
Specific embodiment
The utility model is further elaborated and is illustrated with Figure of description combined with specific embodiments below:
Referring to FIG. 1, a kind of graver, the cutter head 20 including knife handle 10 and set on 10 one end of knife handle.
Cutter head 20 includes a supporting surface 21, protrudes from the boss 22 of the supporting surface 21 and the blade set on supporting surface 21
23, wherein supporting surface 21 be one perpendicular to knife handle axial line plane, boss 22 is set to the side of supporting surface 21, and blade 23 is
Polycrystalline diamond is made.Wherein, blade 23 is fixed on boss 22 and supporting surface 21 by vacuum brazing, and the solder of soldering is copper pricker
Welding powder.
Blade 23 divides to be fixed on the bonding pad 232 of boss 22 and stretch out the point of a knife area 231 of boss 22, bonding pad 232
Including adjacent bottom surface and one side, bottom surface against and be fixed on supporting surface 21, side against and be fixed on boss 22.On side
Equipped with a taper platform outstanding, taper platform is harmonious with the groove for being opened in boss 22.
Specifically, boss 22 includes opposite lower surface and upper surface, a tapered surface is equipped between upper surface and lower surface
221 and a vertical plane 222, vertical plane 222 be one perpendicular to supporting surface 21 isosceles trapezoid, the side of bonding pad 232 is resisted against
The vertical plane 222.The side of bonding pad 232 is in a rectangular trapezoid.In other embodiments, the side of bonding pad 232 is in isosceles three
It is angular.
Supporting surface 21 is recessed to form an evacuation area far from 22 side of boss.Avoid process and material to be processed or folder
Tool collides.
Blade 23 uses polycrystalline diamond, and hardness is high, and processing abrasion is small, and blade 23 can keep for a long time sharp, and engraving is hard
Matter stone material will not crumble sculptured surface because of the brittleness of stone material, while improve the service life of graver.By being arranged in side
Taper platform opens up groove on boss 22, and taper platform is harmonious with groove so that the positioning of blade 23 is reliable, and taper platform when carving
It can be used as the stability that force transmission element improves blade 23.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
