Abstract
The invention provides a steel substrate metal binding agent for a superhard material product and belongs to binding agents for superhard material products. The steel substrate metal binding agent is characterized in that a steel substrate is heated to 700-980 DEG C, at which the steel substrate is in a red plastic state; then superhard material particles such as diamond particles or CBN particles are squeezed into the surface layer of the steel substrate in the plastic state by a high-speed stamping or rolling method; after the steel substrate is cooled, the superhard material particles squeezed into the surface layer of the steel substrate are tightly wrapped and clamped owing to the contraction force of the steel substrate, so that the surface layer of the steel substrate forms a superhard material layer, of which the thickness can be achieved by heating the steel substrate and squeezing superhard material repeatedly. During use, the superhard material layer serves the functions of cutting and grinding together with the steel substrate, is resistant to abrasion, has a long service life, produces low pollution and is low in cost.
Description
Technical field
The invention belongs to the bonding agent of superhard material products, especially relate to a kind of metallic bond of superhard material products.
Background technology
In the making of superhard material products, mainly with ceramic bond, resinoid bond and metallic bond, make superhard material products.The major function of above-mentioned bonding agent is: control firmly superhard material, make in use difficult drop-off of superhard material, extend the work-ing life of superhard material and the different shape of satisfying the demand.Wherein, in metallic bond, be divided into again metal-powder (as powder metallurgy) sintering, plating and soldering etc. (refer to book of reference: " and superhard material and goods ' ' 309 pages of chapter 4 of the mat woven of fine bamboo strips it " bonding agent of diamond abrasive tool "; press of Zhengzhou University in October, 2006 mat woven of fine bamboo strips one-step print); but electroplate seriously polluted; be the strict project of controlling of country, need ring upon ring; And soldering is that superhard material particle is welded in steel matrix, its main drawback is that cost is high.
Summary of the invention
The object of the invention is to propose a kind of steel matrix metallic bond of superhard material products, this steel matrix metallic bond energy part replacing electroplating, soldering, by superhard material: if diamond or CBN are the top layer that is held in steel matrix, not only non-environmental-pollution, and cost is low, is suitable for and applies.
The object of the present invention is achieved like this: a kind of steel matrix metallic bond of superhard material products (being called for short steel matrix metallic bond), comprise steel matrix and superhard material, this steel matrix can be 65Mn steel or 45# steel or other steel grades, steel grade is selected in design according to superhard material products, this steel matrix is for cutting, grinding or set up wearing layer, this superhard material is mainly diamond, CBN and aggregate thereof and WC, it is characterized in that: first described steel matrix is heated to the red Like of moulding state (being that Heating temperature is spent in 700 degree-980), then by the method for high speed stamping or rolling, the particle of superhard material is expressed in the top layer of the steel matrix that is plastic state as the particle of diamond or CBN, after described steel matrix is cooling, rely on the convergent force of steel matrix material itself, the particle that is squeezed into the superhard material in the top layer of steel matrix is teamed tightly, make the top layer of described steel matrix form ultra hard material layer, and the particle that the thickness of this ultra hard material layer can be by repeatedly (repeatedly) heating steel matrix and repeatedly (repeatedly) pushes superhard material is realized, in use this ultra hard material layer and the cutting of steel matrix shared, the function of grinding, not only wear-resisting, long service life, and pollute few, cost is low.
This steel matrix metallic bond is because having utilized the material of steel matrix own, make simple, of many uses, can be used for: saw blade and circular saw machine that various metals and non-metallic material sawing are used, the drill bit that various oil, geology, mine construction are used, and emery wheel, mill, wearing piece, liner plate and steel rolling guide etc.
The manufacturing process flow of the steel matrix metallic bond of this superhard material products is as follows:
1,, according to the design requirements of superhard material products, select steel matrix material and this steel matrix is processed into required shape.
2, the design requirements of root Ju superhard material products, selects the model of superhard material, as selected the model of diamond or CBN, selects the ultimate compression strength of superhard material, and the shape of this superhard material particle, particle diameter are all selected according to design.
3, select heating installation and type of heating: heating installation is general high temperature Car formula stove, Frequency Induction Heating and high-frequency induction heating, adopts the type of heating of general resistive heating, fuel gas injection combustion heating.
4, select punching press or rolling equipment: adopt general fixedly table press (being punch press), hydraulic press and be the custom-designed hot rolls of superhard material products, (illustrating: this custom-designed hot rolls is intended applying for a patent in addition, therefore be not further described in this article).
5, by the particle bond of the superhard material of selecting on the travelling belt of making of adhesive tape, again this adhesive tape is bonded on the upper and lower mould of press tool or on the top layer of the top and bottom rolls of hot rolls, or directly with glue by the particle bond of the superhard material of selecting on upper and lower mould, and according to the design needs of superhard material products, the particle of selected superhard material can bond unidirectional or two-wayly, the i.e. particle of unidirectional on upper and lower mould or on the top layer of top and bottom rolls or this superhard material that simultaneously bonds, the arranging density of the particle of this superhard material is determined by the design concentration of superhard material products.
6, heating: utilize selected heating installation and type of heating, selected steel matrix is heated to the red state of moulding, be heated to 700 degree-980 degree, and the control of this Heating temperature adopts general temperature measurer to carry out observing and controlling as thermopair, far infrared temperature measurement instrument.
7, by being heated to the red Like of moulding state, (reach Heating temperature: steel matrix 700 degree-980 degree) is sent in the upper and lower mould of selected equipment or between top and bottom rolls, carried out punching press or rolling, make steel matrix viscous deformation, and selected superhard material particle is squeezed in the top layer of steel matrix, now, punching press, the temperature of the steel matrix of rolling can not be lower than 700 degree, otherwise selected superhard material particle meeting is broken, push not enter in the top layer of steel matrix, simultaneously, when punching press, must guarantee the amount of plastic deformation of steel matrix, the volume that the superhard material particle in steel matrix top layer is entered in this punching press can make the steel matrix material of same volume extend to surrounding, therefore can not punching press in the die cavity up and down of sealing.
The steel matrix metallic bond of superhard material products proposed by the invention, this steel matrix metallic bond energy Substitute For Partial is electroplated, brazed products, by superhard material: if diamond or CBN are being held in the top layer of steel matrix, non-environmental-pollution not only, and cost is low, is suitable for and applies.
Now in conjunction with the accompanying drawings and embodiments the steel matrix metallic bond of superhard material products proposed by the invention is further described.
