Description
Technical field
It is used for the anti abrasive alloy material without rivet interlacement machine the present invention relates to a kind of.
Background technology
With science and technology and industrial expansion, higher requirement is proposed to material, such as higher intensity, high temperature resistance,
High pressure, low temperature, corrosion-resistant, abrasion and other specific physicals, the requirement of chemical property.Hard alloy is given birth to powder metallurgic method
Production, the composite being made up of refractory metal compound (hard phase) and binding metal (Binder Phase).The spy of hard alloy
Point is that hardness is high, thermohardening is good, high abrasion resistance, and cutting speed improves 4-7 times than high-speed steel, is used as cutter material,
Its wearability is 15-20 times of high-speed steel, the life-span can improve 5-80 times.So hard alloy with its excellent performance just more
Occasion substitute other cutter materials, the more commonly used sintered carbide tool material is tungsten carbide base carbide alloy, but carbonization
Though tungsten base cemented carbide wearability is high, toughness is poor, and fragility is higher, expensive.Therefore need to study a kind of cost low and comprehensive
Close the trend that the good hard alloy of performance has developed into hard alloy.
The content of the invention
The present invention provides a kind of with high rigidity, high intensity, high tenacity, high-wearing feature, and wear rate is low good during high-speed cutting
Advantage be used for the anti abrasive alloy material without rivet interlacement machine.
The technical scheme is that：It is a kind of to be used for the anti abrasive alloy material without rivet interlacement machine, including following step
Suddenly：Compound loads stock mould intracavitary, and in the presence of the pressure of press ram, pressure is transmitted to the compound in die cavity, together
When in the presence of forming agent, compound into pressed compact, pressed compact is placed in vacuum-sintering atmosphere and heated, with temperature by closely knit
Rise, when reaching paraffin evaporating temperature, paraffin escape from pressed compact, obtains finished product, the compound including tungsten carbide, cobalt powder,
Tantalum, niobium, vanadium.
In a preferred embodiment of the present invention, the temperature of the heating is 125 DEG C.
In a preferred embodiment of the present invention, the overall component tungsten carbide of each composition of the compound accounts for 15%, cobalt powder and accounted for
35%th, tantalum, which accounts for 10%, niobium and accounts for 30%, vanadium, accounts for 10%.
The a kind of of the present invention is used for the anti abrasive alloy material without rivet interlacement machine, with high rigidity, high intensity, high-ductility
Property, high-wearing feature, wear rate low good advantage during high-speed cutting.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
Wherein, comprise the following steps：Compound loads stock mould intracavitary, in the presence of the pressure of press ram, pressure
Power is transmitted to the compound in die cavity, while in the presence of forming agent, pressed compact, into pressed compact, is placed in vacuum and burnt by compound by closely knit
Tie in atmosphere and heat, with the rise of temperature, when reaching paraffin evaporating temperature, paraffin is escaped from pressed compact, obtains finished product, described
Compound includes tungsten carbide, cobalt powder, tantalum, niobium, vanadium.
Further illustrate, the temperature of the heating is 125 DEG C, the overall component tungsten carbide of each composition of compound accounts for 15%,
Cobalt powder, which accounts for 35%, tantalum and accounts for 10%, niobium and account for 30%, vanadium, accounts for 10%.
Further illustrating, by refractory metal hard compounds（Tungsten carbide, ramet etc.）, binding metal（Cobalt powder or nickel
Powder）And a small amount of additive（Stearic acid or Yi Suomin）By dispensing, mixed and ground in hexanes trituration medium, add stone
The slurry of wax, then it is vacuum dried（Or spray drying）, sieving, granulation, be made and mix wax compound.Pressing principle：By compound
Load stock mould intracavitary, in the presence of the pressure that press ram or other transmission media are bestowed, pressure is transmitted in die cavity
Powder, powder is subjected to displacement and deformed, with the increase of pressure, and the distance between powder particle diminishes, and occurs between powder particle
Mechanical engagement, porosity is substantially reduced, while in the presence of forming agent, compound by it is closely knit into definite shape, size,
The pressed compact of density, intensity.On the basis of ensureing that forcing press, mould and compound meet pressing requirements, effective means control is utilized
Various influence factors during system, finally give the pressed compact of high-precision size.Due to rubbing between powder particle and mold wall
Wiping is acted on, and pressure is produced decay in pressed compact short transverse, is caused the weight change in pressed compact unit height, that is, reflect pressed compact
The change of density.Low pressure sintering principle：Heat under vacuum, carry out vacuum dewaxing and sintering process, be conducive to despumation,
Sintering atmosphere purity is improved, improves the wetability of Binder Phase, promotes reaction；Simultaneously at a sintering temperature by pressurization in production
On product, promote product to be further densified, eliminate the defect of product, improve the combination property of product.The present invention provides a kind of use
In the anti abrasive alloy material without rivet interlacement machine, with high rigidity, high intensity, high tenacity, high-wearing feature, during high-speed cutting
The low good advantage of wear rate.
The embodiment of the present invention, but protection scope of the present invention is not limited thereto, it is any to be familiar with this area
Technical staff disclosed herein technical scope in, the change or replacement that can be expected without creative work should all be contained
Cover within protection scope of the present invention.Therefore, the protection model that protection scope of the present invention should be limited with claims
Enclose and be defined.
