Description
Technical field
The present invention relates to abrasive tool industry, more particularly to a kind of the moulding process and graphite of the diamond roller of finishing grinding wheel
Matrix.
Background technology
Diamond roller, is high efficiency, the high life of the special purpose machine tool and Gear Processing for high-volume form grinding, low
The truer of cost.By on the trimming device of grinding machine, diamond roller trimming conventional ceramic grinding wheel or CBN
Grinding wheel is regrinded after abrasive wheel forming and cuts part, to copy to the appearance profile of diamond roller and precision, size by grinding wheel
Processed piece surface.
In the prior art, publication No. is that the patent of invention of " CN102490255A " discloses a kind of finishing vitrified bond
The thin slice diamond roller manufacturing process of CBN grinding wheels, by being sintered the diamond on table graphite matrix surface to material progress
Finishing, by the way that diamond screen is placed on the inner face of graphite matrix, by compacting in subsequent handling and
Sintering makes diamond roller global formation, but this kind of mode needs manually to carry out diamond the screening of grain size, while rolling
During wheel rotation, diamond particles are since the tangential force being subject to is larger, and during high-speed rotation, smart steel stone may be from
It is fallen off on idler wheel, affects the wear-resisting property of diamond roller.
Invention content
The object of the present invention is to provide the moulding process that a kind of wearability preferably modifies the diamond roller of grinding wheel.
The present invention above-mentioned technical purpose technical scheme is that：A kind of diamond of finishing grinding wheel
The moulding process of idler wheel, includes the following steps：
Step 1: by diadust and additive be placed into molding die annular groove in, be pressure bonded to thickness be 1 ㎜ and
Width carries out microwave sintering after being 3 ㎜, and sintering temperature is formed compound in 1841 ℉ -1853.6 ℉, duration 1h-1.1h after sintering
Diamond chip；
Step 2: processing graphite matrix, the placing groove being arranged for graphite core, the bottom of placing groove are processed at the center of graphite matrix
Portion is the lower pressure ring that can be moved up, and the surface of graphite matrix processes the groove placed for composite diamond piece side, groove edge
The thickness direction of black matrix extends through one side, and the width of groove is equal to the one third of the width of composite diamond piece extremely
Half；
Step 3: fill metal tungsten powder in placing groove fills bonding agent to higher than groove surfaces, and in groove vicinity, by pre-
Metal tungsten powder is depressed into the pressure of 27-29Mpa and is flushed with the surface of groove by casting die by metal tungsten powder at normal temperatures；
Step 4: composite diamond piece is placed into groove by hand, precompressed identical with groove shapes size is then placed into
Composite diamond piece above groove is pressure bonded in groove by part, is then covered above the composite diamond piece in placing groove
It is stamped the bonding agent of 1-2mm thickness, is continued to fill up in placing groove and step 3 moderate metal tungsten powder；
Step 5: the top lid in placing groove closes pressure ring, apply the pressure of 27-29Mpa on upper press ring, while in upper press ring
By metal tungsten powder, frequency conversion is compacted to form the training of idler wheel hair repeatedly with the active force of application 35-39Mpa on lower pressure ring；
Microwave sintering is carried out Step 6: idler wheel hair is trained, then machining carries out finishing molding.
By using above-mentioned technical proposal, composite diamond piece by the way that diadust microwave sintering is formed, compared to
Diamond particles have the structural strength of stronger hardness and globality, while avoiding the big of diamond particles in background paper
It is small to screen and towards the problem of screening；Polishing effect of composite diamond piece during to grinder buffing that thickness is 1 ㎜ compared with
Good, rub proofness and the service life is longer；Metal tungsten powder is depressed by the pressure of 27-29Mpa and is flushed with the surface of groove, side
The top and bottom in composite diamond piece is arranged during microwave sintering in the placement that continues composite diamond piece after an action of the bowels
Bonding agent make annular composite diamond piece is preferably combined with metal tungsten powder, to composite diamond piece play reinforcement structure with
Fixed effect passes through the process of precompressed so that metal tungsten powder can be combined with the surface of composite diamond piece, facilitate second pressing
And sintering circuit, while the problem of avoid a pressure excessive, composite diamond piece is caused to be broken；In order to avoid filling out twice
The problem of being compacted after filling metal tungsten powder, causing to be broken during being compacted intermediate position between twice in sintering, it is first
The pressure for first passing through 27-29Mpa carries out precompressed, avoids metal tungsten powder really up to the mark, but the surface for being also prevented from metal tungsten powder formation is excessively soft,
Avoid composite diamond piece in bonding processes right by the pressing of upper and lower both sides centering to the larger side deformation fracture of deflection
Composite diamond piece play the role of it is fixed, while under the pressure of the 35-39Mpa of second pressing so that more soft
Metal tungsten powder can be closely combined together, and avoid the breakage problem of idler wheel during use.
Preferably, sintering temperature is 1850 ℉, duration 1h in step 1.
Preferably, the width of step 2 further groove is the half of composite diamond piece.
Preferably, the frequency that frequency conversion is compacted in step 5 is 10-15 times per minute.
Preferably, microwave sintering temperature is in 850 ℉, duration 3h-4h in step 6.
Another object of the present invention is to provide a kind of graphite matrixes corresponding with above-mentioned moulding process.
The present invention above-mentioned technical purpose technical scheme is that：It is a kind of to be applied to modify grinding wheel
The graphite matrix of the moulding process of diamond roller, including matrix bodies, the upper end of described matrix ontology downwards concave shape at
For the placing groove of the annular of metal tungsten powder filling, the placing groove is centrally formed with fixed column, the upper end of described matrix ontology
Face is along the groove for extending axially inwardly the annular being arranged concentrically with fixed column of fixed column, the circumference of the groove of the annular
Face is penetrated through with placing groove, and the lower pressure ring axially lifted in placing groove along fixed column is arranged in the fixed column, described to put
The bottom perforation for setting slot is provided with the pressure holes to press for force object, and the opposite ring set that pushes is equipped in fixed column in the fixed column
The upper press ring axially lifted, in the upper press ring sliding be connected with annular slipping block corresponding with groove, the slipping block with
The gap of clamping composite diamond piece is formd between groove.
By using above-mentioned technical proposal, during upper and lower pressing, upper press ring and lower pressure ring can be jointly to grooves
Position is moved, and centring property is more preferable so that the pressure of both sides is identical above and below composite diamond piece, avoids composite diamond piece
It being broken in groove location, annular slipping block plays preferable guide effect, avoids the non-uniform problem of upper press ring pressure,
During pressure, annular slipping block and fit depressions are avoided stress concentration at the compound gold compared with strong structure intensity
Hard rock on piece；The pressure holes being arranged on matrix bodies, which play, facilitates forcing press to press, and wedge block is inserted into pressure holes
After between lower pressure ring bottom, there is preferable pressure maintaining effect to the molding diamond roller in its inside, metal tungsten powder is made to press
Microwave sintering is carried out under power state.
Preferably, the end face of described matrix ontology forms locating slot, the positioning along the recess axially inwards of fixing axle
