Abstract
The invention relates to a metallic bond used for a man-made diamond circular saw blade, which mainly comprises the following components: copper, iron, carbon, tungsten, powdered nickel and chromium. The metallic bond used for the man-made diamond circular saw blade adopts mixed powder of coarse tungsten carbide, copper, iron, nickel and chromium alloy as raw materials without using expensive cobalt and alloy thereof, thereby lowering the processing difficulty and the manufacture cost, having wider sintering temperature range and better bonding property, and being suitable to cut concrete and hard granite.
Description
Technical field
The present invention relates to a kind of multiple alloy powder that contains, particularly be used in the cutting processing concrete, hard granite contains the diamond saw blade metallic bond of coarse granule diamondite particle, is specially a kind of metallic bond that is used for man-made diamond circular saw blade.
Background technology
Diamond circular saw is made up of steel circular base and the sawtooth (containing adamantine cutter head) that is distributed in the circular base periphery.Contain the workpiece that adamantine cutter head is a saw blade, after the shape of matrix was determined, the serviceability of saw blade was decided by the performance of cutter head.Cutter head is made up of metallic bond and diamond, common adamantine grade, and after granularity and the concentration decision, a crucial factor is exactly the performance of bond.The serviceability of diamond saw blade is except the form and diamond Effect on Performance that are subjected to the steel matrix, and its performance depends on that diamond suitably cooperates with bond and the overall performance of the saw blade tip composite that constitutes.This relates generally to type, composition proportion, relative density, metallographic structure, mechanical property and the bond of bond and the form of the adhesion between the diamond.Bond commonly used in the production has several classes such as copper base, cobalt-based, tungsten base, iron-based, use in the saw blade in cuttings such as concrete and hard granite, the preparation of diamond saw blade metallic bond is used usually and is contained the cobalt chemical analysis, and be narrower than 200 purpose elemental metals powder or alloy powders, because metallic cobalt powder fine size, the price height makes cutter head production cost height, has weakened the competitive advantage of product.
Summary of the invention
The invention provides a kind of metallic bond that is used for man-made diamond circular saw blade, do not contain the noble element cobalt, reduced cost of raw, particularly adopt coarse tungsten carbide (WC), reduced the technology cost, promoted competitiveness of product.
At above technical problem, the present invention by the following technical solutions, a kind of metallic bond that is used for man-made diamond circular saw blade mainly comprises following composition: copper, iron, carbon, tungsten, nickel powder and chromium.
Of the present inventionly further be optimized for: a kind of metallic bond that is used for man-made diamond circular saw blade, the percentage by weight of main material composition is: copper 30-55%, iron 5-25%, carbon 0.36-1.20%, tungsten 5.64-18.8%, nickel 5-15%, chromium 1-8%.
Diamond disc metallic bond of the present invention avoids using expensive cobalt and alloy thereof, but adopt the mixed-powder of coarse tungsten carbide, copper, iron, nickel, evanohm is raw material, difficulty of processing and manufacturing cost have been reduced, have the sintering range and the good binding ability of broad, be applicable to the cutting of concrete and hard granite.
The specific embodiment
Embodiment one
A kind of metallic bond that is used for man-made diamond circular saw blade mainly comprises following composition: copper, iron, carbon, tungsten, nickel powder and chromium, the percentage by weight of main material composition is: copper 30%, iron 25%, carbon 0.36%, tungsten 5.64%, nickel 15%, chromium 1%.
Manufacture craft is as follows:
1. to copper alloy powder, ferroalloy powder, nickel powder reduce processing respectively.
2. take by weighing all metal dusts by a certain percentage respectively, and add the liquid molding agent (as gasoline rubber solution, atoleine, organic solvents such as isopropyl alcohol) of batching gross weight 0.5% weight.
3. add the diamond of certain mass, all put into batch mixer and evenly mix.
4. in 700-950 degree sintering temperature Celsius moulding.
Experimental stage, we adopt not diamantiferous pure bond sintered body to carry out pressure test.Find that cobalt base bonding agent compressive strength of specimens commonly used is 960-1160Mpa, bond compressive strength of specimens of the present invention is 900--1080Mpa.Its compression strength value all is higher than the requirement that our pure bond sintered body compression strength is not less than 800Mpa.Aspect result of use, we have made Φ 230mm respectively, Φ 300mm, Φ 600mm, the diamond saw blade of Φ 1600mm plurality of specifications, do not have evident difference after tested in the sharpness of saw blade and service life, the respective specification diamond saw piece performance that this bond is made also is better than the cobalt base bonding agent product.Average per kilogram reduces 60-100 circle RMB aspect the metallic bond integrated cost.
The existence of metallic cobalt in the diamond bond can improve the bond performance, and still, cobalt is a rare metal, costs an arm and a leg.This bond does not contain cobalt element, has adopted the lower iron(-)base powder of price that the bond cost is significantly reduced; Since the restriction of production technology, cobalt, elemental metals powder sizes such as nickel are superfine, improved the production technology cost of diamond segment, and this bond adopts the thicker alloy powders such as tungsten carbide of granularity, has reduced the production technology cost of diamond segment.Compare this metal bond with cobalt base bonding agent commonly used in use according to following characteristics are arranged: 1. higher alloying level, avoided the generation of different metal chemical composition segregation.2. good caking property has good wellability to diamond, and metal ingredient and diamond secure bond are beneficial to diamond and play one's part to the full in cutting behind the sintering.3. the sintering temperature interval of broad helps stable mass large-scale production.4. certificate has higher intensity behind the bond sintering, and suitable hardness and wearability are taken into account diamond saw blade cutting efficiency and cutting quantity, show superior combination property.
Embodiment two
With a kind of metallic bond that is used for man-made diamond circular saw blade of embodiment one, difference is that the percentage by weight of main material composition is: copper 42%, iron 15%, carbon 0.78%, tungsten 12.22%, nickel 10%, chromium 5%.And the liquid molding agent (as gasoline rubber solution, atoleine, organic solvents such as isopropyl alcohol) of adding batching gross weight 1.0% weight.
Embodiment three
With a kind of metallic bond that is used for man-made diamond circular saw blade of embodiment one, difference is that the percentage by weight of main material composition is: copper 55%, iron 5%, carbon 1.20%, tungsten 18.80%, nickel 5%, chromium 8%.And the liquid molding agent (as gasoline rubber solution, atoleine, organic solvents such as isopropyl alcohol) of adding batching gross weight 1.5% weight.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
