Abstract
The utility model discloses an integrally sintered sandwich type diamond circular saw blade and relates to the technical field of integrally sintered diamond circular saw blades, in particular to the integrally sintered sandwich type diamond circular saw blade which comprises mixture (1) of metal powder and diamonds, a steel matrix (2) and a metal powder intermediate layer sintered body (3), wherein the mixture (1) of the metal powder and the diamonds is arranged at two ends of the steel matrix (2), and the metal powder intermediate layer sintered body (3) is arranged at an intermediate interlayer of the mixture (1) of the metal powder and the diamonds. The method of performing sandwich type layering processing on powder before cold press molding is adopted, sintering molding is performed after a blank is formed by pressing, and the integrally sintered sandwich type diamond circular saw blade is used after being edged, and the cutting force can be effectively reduced, the generation of cutting heat can be inhibited, the cutting efficiency is greatly improved and the continuity of the cutting process is ensured.
Description
Technical field:
The utility model relates to a kind of at integral sintered diamond disc technical field, is specifically related to the integral sintered diamond disc of a kind of sandwich type.
Background technology:
At present, simple direct compound in the manufacturing process of integral sintered diamond disc with diamond single crystal and metal dust, saw bit matrix is cold-pressed into the saw blade green compact in cold pressing forming mould, after green compact are inserted the ripe base of disposable sintering in the reducing atmosphere stove, to ripe base put the first edge on a knife or a pair of scissors handle after, saw blade can carry out cutting work, the saw blade tip part-structure is single, macroscopical wear morphology on this saw blade saw blade cutting surface in cutting process is middle convex, convex is because the effect of cutting side force causes the regeneration vibrations of saw blade easily, the degree of the discharge of the smear metal that cutting simultaneously produces also has certain limitation, because diamond is irregular distribution in the cutter head in the surface of revolution, the discharge path complicationsization of smear metal, cause easily than multiple the grinding of rough lumber bits and cut, produce multiple dimensional effect, cause cutting force and heat in metal cutting significantly improve.Improve the operating efficiency and the service life of this kind saw blade, granularity that can only be by improving diamond single crystal or the anti-grainding capacity that reduces carcass guarantee the continuation of cutting process.
The utility model content:
The purpose of this utility model provides the integral sintered diamond disc of a kind of sandwich type, it can adopt the preceding way of powder being carried out the layering processing of sandwich type of cold moudling, be pressed into sinter molding behind the green compact, use after putting the first edge on a knife or a pair of scissors, can effectively reduce the generation of cutting force and inhibition heat in metal cutting, so can improve the continuation of cutting efficiency and assurance cutting process widely.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of metal dust and diamond compound 1, steel matrix 2 and metal dust intermediate layer sintered body 3; Steel matrix 2 two ends are provided with metal dust and diamond compound 1, and the intermediate course of metal dust and diamond compound 1 is provided with metal dust intermediate layer sintered body 3.
The way that the utility model adopts the layering of powder being carried out before the cold moudling sandwich type to handle is pressed into sinter molding behind the green compact, and use the back of putting the first edge on a knife or a pair of scissors.Macroscopical wear morphology on sandwich type saw blade saw blade cutting surface in cutting process is middle arcs of recesses, because the wear morphology of middle concave can make the saw blade cutting process obtain assist location effectively, two-way cutting side force directly acts on the intermediate layer cutting object, and it is symmetrical substantially, overall side force to saw blade just significantly reduces, the overall side force that saw blade bears is the exciting source that the saw blade cutting process produces the regeneration vibrations, and the macroscopical wear morphology after this kind cutting can effectively suppress the regeneration vibrations of saw blade.Middle arcs of recesses is also for smear metal provides rational chip space, and the break flour that cutting process produces can therefrom be discharged in the arcs of recesses groove in large quantities, and break flour grinds the possibility of cutting through the diamond secondary to be reduced significantly; The middle concave wear morphology can make the thick bits ratio after cutting object becomes to consider to be worth doing significantly increase, because the cutter head intermediate layer is not diamantiferous powder layer, can make the corresponding cutting object produce smear metal in the cutting process in the mode of bursting apart, the smear metal of bursting apart mostly is than rough lumber and considers to be worth doing, the cutting energy consumption is very low, therefore the dimensional effect of cutting process significantly reduces, and can effectively reduce the generation of cutting force and inhibition heat in metal cutting, so can improve the continuation of cutting efficiency and assurance cutting process widely.
Description of drawings:
Fig. 1 is the background technology structural representation;
Fig. 2 is that background technology is used the back structural representation;
Fig. 3 is the utility model structural representation;
Fig. 4 is that the utility model uses the back structural representation.
The specific embodiment:
Referring to Fig. 3-4, this specific embodiment is by the following technical solutions: it is made up of metal dust and diamond compound 1, steel matrix 2 and metal dust intermediate layer sintered body 3; Steel matrix 2 two ends are provided with metal dust and diamond compound 1, and the intermediate course of metal dust and diamond compound 1 is provided with metal dust intermediate layer sintered body 3.
This specific embodiments is by changing the part relative position of the preceding cold pressing forming mould of cold moudling, for powder provides tri-layer different dress powder spaces; Pack into the compound of diamond and metal dust of upper strata, diamond particles concentration height in the compound; The diamond that intermediate layer powder employing simple metal powder or diamond concentration are low and the compound of metal dust; Lower floor's compound with equal proportioning diamond in upper strata and metal dust of packing into changes cold-press moulding behind the powder over to, and integral sintered, the use of putting the first edge on a knife or a pair of scissors.Sandwich type saw blade cutter head is owing to the diamond concentration of levels is higher than the middle level powder, and antiwear property is better than the middle level powder, in cutting operation, and arcs of recesses during sandwich type saw blade cutter head macroscopic view wear morphology also can occur.
This specific embodiments has following beneficial effect: macroscopical wear morphology on sandwich type saw blade saw blade cutting surface in cutting process is middle arcs of recesses, middle arcs of recesses also provides rational chip space for smear metal, the break flour that cutting process produces can therefrom be discharged in the arcs of recesses in large quantities, and break flour grinds the possibility of cutting through the diamond secondary to be reduced significantly; The middle concave wear morphology can make the thick bits ratio after cutting object becomes to consider to be worth doing significantly increase, because the cutter head intermediate layer is not diamantiferous powder layer, can make the corresponding cutting object produce smear metal in the cutting process in the mode of bursting apart, the smear metal of bursting apart mostly is than rough lumber and considers to be worth doing, the cutting energy consumption is very low, therefore the dimensional effect of cutting process significantly reduces, can effectively reduce the generation of cutting force and inhibition heat in metal cutting, so can improve the continuation of cutting efficiency and assurance cutting process widely, reduce the wasting of resources of cutting object, increase the degree of accuracy height service life of saw blade simultaneously, improve operating efficiency greatly, lowered the waste of diamond resource.
