Description
Technical field
The present invention relates to a kind of emery wheel, particularly a kind of dovetail groove split emery wheel, belongs to grinding tool technical field.
Background technology
At present, the emery wheel mainly monolithic construction of use, namely emery wheel entirety is all be made up of abrasive material, this Integral sand foot wheel abrasion just can not continue to use to a certain extent, remaining emery wheel can only be abandoned, need to change whole emery wheel, cause waste of material, utilization rate is low, increases use cost.And when high-speed grinding, easy stressed breakage, dangerous.In manufacturing process, because mold pressing is uneven, sinter the reasons such as wayward, the emery wheel quality of making differs, and percent defective is high.The emery wheel that diameter is larger is like this, the problems such as such as more than the emery wheel of 500mm, and monoblock type emery wheel also needs the input of large scale production equipment, there is investment of production large, and production cost is high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of dovetail groove split emery wheel, and its investment of production is little, produce and use cost low, security is good, thus overcomes the deficiency of existing monoblock type emery wheel.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of dovetail groove split emery wheel, it forms the metallic matrix comprising annular and the wheel grinding layer be fixed on metallic matrix outer peripheral face, described wheel grinding layer is combined by least two pieces of wheel grinding blocks, the outer peripheral face of metallic matrix there is dovetail groove, there is the dovetail shaped corresponding with the dovetail groove of metallic matrix protruding in the bottom of wheel grinding block, the dovetail shaped projection of wheel grinding block embeds in the dovetail groove of metallic matrix, is fixed on metallic matrix by wheel grinding block; Chimeric place that is protruding at dovetail shaped and dovetail groove leaves gap.
In above-mentioned dovetail groove split emery wheel, described metallic matrix is aluminium alloy or titanium alloy substrate, described wheel grinding block sinters with diamond and bonding agent to form, bonding agent used is glass based on mica glass ceramic, titanium dioxide is made as nucleator, and the chemical composition of this parent glass is as follows: K
2o 5 ~ 10%, MgO 10 ~ 18%, Al
2o
310 ~ 20%, B
2o
32 ~ 5%, TiO
21 ~ 4%, ZrO
21 ~ 4%, Na
2o+K
2o 3%, KF 5 ~ 12%, ZnO 4 ~ 8%, all the other are SiO
2.
In aforesaid dovetail groove split emery wheel, dovetail shaped is protruding is sintering integrated shaping with wheel grinding block, and the sidewall of dovetail shaped projection and the included angle A of bottom are 30 ~ 60 degree.
In aforesaid dovetail groove split emery wheel, the sidewall of dovetail shaped projection and the included angle A of bottom are preferably 45 degree.
In aforesaid dovetail groove split emery wheel, dovetail groove notch shape is outer little greatly interior.
In aforesaid dovetail groove split emery wheel, between adjacent wheel grinding block, leave gap.
Beneficial effect of the present invention: compared with prior art, the present invention adopts split-type structural, emery wheel is made up of metallic matrix and the wheel grinding layer be fixed in metallic matrix outer rim, when grinding layer may wear to a certain degree, only need to change grinding layer, change easily, without the need to changing whole emery wheel, save material, improve emery wheel utilization rate, reduce use cost.And due to wheel grinding layer be spliced by polylith wheel grinding block, the volume of wheel grinding block is little, without the need to using large scale production equipment, investment of production is little, cost is low, and manufacture craft more easily controls, and percent defective is low, other wheel grinding block individual is the quality that waste product can not affect other wheel grinding blocks, reduces production cost.Its matrix adopts the metallic matrix such as aluminium alloy or titanium alloy, can not burst, have higher use linear velocity.And dovetail groove notch on matrix is outer little greatly interior, by the shape of dovetail groove, wheel grinding block can be blocked, wheel grinding block is more firmly fixed, prevent wheel grinding block from coming off from matrix in grinding process, the present invention is protruding at dovetail shaped leaves gap with chimeric place of dovetail groove, can filled thermoset resin in this gap, sinter-hardened by hot pressing, guarantee that wheel grinding block does not drop, security is good.Wheel grinding block of the present invention selects the vitrified bond system based on mica glass ceramic and suitable glassy phase, this system has the features such as higher Mechanics of Machinery intensity, good thermal shock, resistance to chemical attack, nucleation temperature 720 DEG C, crystallization temperature 810 and most high sintering temperature, lower than 900 DEG C, are diamond (CBN) the wheel ceramic bonding agents that a kind of performance is extremely excellent.
