Description
Technical field
The present invention discloses a kind of manufacture method of emery wheel, belongs to the technical field of emery wheel making.
Background technology
In conventional mechanical processing, emery wheel is referred to as the tooth of machining, is usually used in the machining of hard material.Emery wheel one
As made using " dry-pressing formed ".Wherein, Carborundum wheel is due to the superhard performance of its abrasive material, normal quilt even more in grinding
The emery wheel chosen.In grinding, emery wheel sharp and can to repair be important performance indications.In existing technology, gold
Emery wheel commonly uses " dry-pressing formed " to make Carborundum wheel blank, then carries out follow-up sintering, and the process such as finishing is formed；Or electricity consumption
Diamond dust method is plated to make.
If Carborundum wheel is made using " dry-pressing formed " method, its blank inner homogeneous degree and consistency are direct close
Join the quality for the Carborundum wheel being finally fabricated to.Defect caused by blank forming process is often Carborundum wheel product
Main hazard defect, controls and eliminates these defects and produce objective requirement, promote Carborundum wheel moulding process to deepen continuously research
And innovation.In general, " dry-pressing formed " is the Carborundum wheel blank fabricated using granulation material, and its internal density is equal
Even property is poor.
Based on this, the work that applicant thinks existing emery wheel, especially Carborundum wheel with the forming method of dry-pressing to manufacture
Skill could be improved.In addition, the also production technology of carborundum electroplating wheel, due to the emery grit adhesive force of plating up not
By force, easily dropped in grinding, cause ground effect to decline, cause that carborundum electroplating wheel service life is short again, so high-rate grinding
Carborundum electroplating wheel is not selected in interruption.Due to above-mentioned two reasons, to make high-quality emery wheel, thus this case produces.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of emery wheel, the emery wheel density that is manufactured by this method is big,
Fracture strength is high.
To reach above-mentioned purpose, the technical solution adopted in the present invention is：
A kind of manufacture method of emery wheel, comprises the following steps：First using the metal dust batch mixing containing abrasive material as raw material, and using note
Penetrate molding procedure and emery wheel blank is made, then emery wheel blank sequentially passes through de- glutinous process, sintering circuit, most afterwards through electric spark shaving
Into finished product.
In the present invention, because injection moulding is to use the metal dust batch mixing containing abrasive material（Belong to viscoplasticity material）To process
Shaping blank, made emery wheel blank inner materials uniformity is good, it is sintering finished after, density is big, and fracture strength is high, after being easy to
Continuous de- glutinous, sintering and electric spark shaving, are finally made intensity and grinding sharpness all reach the emery wheel of use requirement.
As the further setting of above-metioned scheme, the injection moulding process is carried out using injection machine, including will contain mill
The metal dust batch mixing of material is in the state of HTHP, and injection enters in mold cavity, generates emery wheel blank, high temperature therein
For 180 DEG C ± 30 DEG C, high pressure is 70Mpa ± 25Mpa.
The de- glutinous process is carried out using de- glutinous stove, and nitric acid or oxalic acid are added when taking off glutinous as acid catalyst, nitrogen is added
As vector gas, take off it is glutinous during, temperature is raised to 120 DEG C ± 20 DEG C from normal temperature, 0.2 DEG C/minute ± 0.01 DEG C of heating curve/
Point, it is 12-20 hours to take off the glutinous time.
The sintering circuit is carried out using vacuum sintering furnace, and makees gas shield sintering using hydrogen or nitrogen, is sintered
Maximum temperature control is at 1350 DEG C ± 50 DEG C, and sintering time is 16-18 hours.
The emery wheel blank can be sheet, columned, cone shape or other geometry shapes.
The abrasive material is any one in diamond dust, carborundum, boron carbide.Certainly, according to the actual requirements, it can also be
Other kinds of abrasive material.
A kind of manufacture method of emery wheel of the present invention, its blank inner materials are uniform, and the sintering finished rear density of institute is big, and fracture is strong
Degree is high, and after last electric spark shaving, wheel grinding is sharp.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Brief description of the drawings
Fig. 1 is the working state schematic representation of injection moulding process in the present invention.
Embodiment
A kind of manufacture method of emery wheel of the present invention, comprises the following steps：First using the metal dust batch mixing containing abrasive material as raw material, and
Emery wheel blank is made using injection moulding process, then emery wheel blank sequentially passes through de- glutinous process, sintering circuit, most afterwards through electric fire
Flower is trimmed to finished product
In the present embodiment, injection moulding process is carried out using injection machine, including by the metal dust batch mixing containing abrasive material in high temperature
In the state of high pressure, injection enters in mold cavity, generates emery wheel blank, and high temperature therein is 180 DEG C ± 30 DEG C, and high pressure is
