Description
Technical field
This utility model relates to diamond techniques field, particularly a kind of diamond-impregnated wheel.
Background technology
Diamond-impregnated wheel is the one in diamond tool, it is primarily adapted for use in the flat surface grinding processed of all kinds of refractory surface, product uses specially designed taper structure of mounting hole, it is prone to handling, flatness is good, grinding efficiency is high, life-span advantages of higher to have processing, is applicable to all domestic and imported equipment for grinding.
High speed development along with modern science and technology, the grinding tool kind of superhard material gets more and more, its performance obtains development and raising, and diamond-impregnated wheel has high abrasion, high tenacity, the high lot of advantages such as heat-resisting so that diamond-impregnated wheel is increasingly favored by people.
Traditional diamond-impregnated wheel is directly welded in diamond segment in steel matrix through silver soldering sheet, silver brazing agent, the diamond-impregnated wheel weld strength being so welded is low, resistance to corrosion is low, and the most rectangular piece of diamond segment, when cutting, due to existence and the less reason of quantity of corner angle when diamond segment contacts with actor, easily cause the abrasion of diamond segment, and easily cause and come off, after diamond segment once comes off, whole diamond-impregnated wheel will be scrapped, and causes the serious wasting of resources.
nullIn the Chinese patent of Patent No. 201420270854.7，Disclose a kind of novel PCD emery wheel，Bowl-shape steel matrix (1) including opening，It is characterized in that，The center of steel matrix (1) bottom is provided with the first through hole (2)，Steel matrix (1) side is provided with the most uniform multiple second through holes (3)，Steel matrix (1) upper end is provided with around its outer edge surface and outwardly directed upper surface (4)，Upper surface (4) be milled with respectively near inner ring and outer ring multiple interlaced the most uniform and with the upper surface (4) notch in 15 degree of inclinations angle，Notch is provided with identical silver soldering sheet，PCD block (5) it is welded with on silver soldering sheet，The diamond layer (7) that PCD block is sintered by hard alloy pedestal (6) and hard alloy pedestal (6) upper surface is constituted，The surrounding of PCD block is coated with one layer of copper (8).”
PCD block in this patent is all rectangular block; and it is distributed on the surface of steel matrix; this diamond often occurs the situation that PCD block weares and teares during the use that we are long-term; and PCD block the most easily comes off; after long-time research; tracing it to its cause, the emery wheel of this structure deposits unstability structurally, so this patent finds a kind of new structure to solve this problem.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of diamond-impregnated wheel, effectively solves that traditional diamond-impregnated wheel cutter head cutting is the sharpest, easily cause abrasion and the problem come off.
Its technical scheme solved is, it is bowl-shape steel matrix including opening, the first central through hole it is provided with bottom steel matrix, steel matrix upper end is provided with around its outer edge surface and outwardly directed upper surface, upper surface is provided with many groups around the most uniform cylindrical notch of upper surface, silver brazing sheet it is placed with in notch, silver brazing sheet is welded with cylinder diamond segment through silver brazing agent, often group diamond segment is linear and mutually non-cross, often the group inclined lineal layout of diamond segment is between the interior radial line edge of upper surface to outer radial line edge, steel matrix sidewall is provided with multiple the second the most uniform through hole.
This utility model simple in construction, owing to diamond-impregnated wheel has become as the most ripe prior art, this use Novel warp is crossed and is studied for a long period of time, still fundamentally improve from structure, making diamond-impregnated wheel sharper, diamond segment is not easy abrasion and comes off, and extends service life.

Fig. 3 is this utility model top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Be given by Fig. 1 to Fig. 3, this utility model includes that opening is bowl-shape steel matrix 1, the first central through hole 2 it is provided with bottom steel matrix 1, steel matrix 1 upper end is provided with around its outer edge surface and outwardly directed upper surface 3, upper surface 3 is provided with many groups around the most uniform cylindrical notch of upper surface 3, silver brazing sheet it is placed with in notch, silver brazing sheet is welded with cylinder diamond segment 4 through silver brazing agent, often group diamond segment 4 is linear and mutually non-cross, often the group inclined lineal layout of diamond segment 4 is between the interior radial line edge of upper surface 3 to outer radial line edge, steel matrix 1 sidewall 5 is provided with multiple the second the most uniform through hole 6.
The second described through hole 6 quantity has 8.
Described often group diamond segment 4 has 7-14.
When this utility model uses,
Compared with the documents in background technology, this utility model is structurally innovated, cylinder cutter head 4 is for traditional rectangle cutter head, when just contacting cutting, it is not easy to cause abrasion diamond segment because overexerting, and cylinder cutter head 4 cuts sharper when cutting, multiple cylinder diamond segments 4 are arranged into straight line, and inclined angle from one end of upper surface to the other end, cause when cutting, cutting is uniformly, can mutually protect, a certain diamond segment will not be worn and torn for a long time, and then extend the service life of diamond segment, cylinder diamond segment 4 in cutting process due to multiple mutually arranged, and diamond segment is welded in notch through silver brazing agent, make that diamond segment is more difficult to come off.
First central through hole 2 is used for installing cutting tool.
Second through hole 6 is used for accelerating chip removal speed and drainage speed.
This utility model simple in construction, owing to diamond-impregnated wheel has become as the most ripe prior art, this use Novel warp is crossed and is studied for a long period of time, still fundamentally improve from structure, making diamond-impregnated wheel sharper, diamond segment is not easy abrasion and comes off, and extends service life.
