Abstract
A compound diamond grinding block comprises cutter heads and a clamping piece. The cutter heads adopt diamond cutter heads combined by metal binder and are embedded in a rubber layer; the rubber layeris arranged on the clamping piece; the cutter heads are uniformly distributed in the rubber layer; the bottom parts of the cutter heads penetrate through the rubber layer and are connected with the clamping piece or the rubber layer is arranged between the bottom parts of the cutter heads and the clamping piece. The compound diamond grinding block adopts the diamond cutter heads combined by the metal binder to be combined with the rubber, so that on one hand, the grinding efficiency and the grinding life of the diamond cutter heads are improved through utilizing strong holding ability of themetal binder to the diamond; on the other hand, the bonding technology of the metal binder and the rubber is utilized to realize the chemical combination of the rubber and the metal binder, thereby ensuring that the rubber can firmly wrap and hold the diamond cutter heads and realizing ideal grinding effect; and the compound diamond grinding block has the characteristics of low cost and low energyconsumption.
Description
Technical field
The utility model relates to a kind of composite diamond abrading block.
Background technology
A kind of diamond rubber abrasive wheel is disclosed among the Chinese patent literature CN 2336918Y; comprise inner protective layer; grinding layer and external protection; grinding layer is the annular frame by diamond particles and rubber mix heating back moulded section, internal circular surfaces and outer round surface viscose fibre cloth and form inner protective layer and external protection.Because diamond particles is difficult to and the rubber combination, hit at the reality mill, diamond particles comes off from rubber especially easily or is absorbed in the rubber, so the abrasive wheel of this kind structure can not realize high-rate grinding, and simultaneously, its service life is also quite short.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, grinding efficiency is high, ground effect good, the composite diamond abrading block of long service life, parcel dependable performance, to overcome weak point of the prior art.
A kind of composite diamond abrading block by this purpose design comprises cutter head and holder, it is characterized in that cutter head is the diamond segment of metallic bond combination, and this cutter head is embedded in the rubber layer, and rubber layer is arranged on the holder.
Described cutter head is more than one, is distributed in the rubber layer.
The bottom of described cutter head joins with holder after passing rubber layer, perhaps, is provided with rubber layer between the bottom of cutter head and the holder.
The cross section of described cutter head is triangle, quadrangle, pentagon, hexagon or polygon.
The shore hardness of described rubber layer is 70～95.
The utility model adopts the diamond segment and the rubber of metallic bond combination to carry out combination, utilize the metallic bond characteristics strong on the one hand to the diamond hold, the grinding efficiency and the grinding life-span of diamond segment have been improved, on the other hand, utilize the technology of cohering of metallic bond and rubber, realize the chemical bond between rubber and the metallic bond, thereby can wrapping up securely, rubber controls the right cutter head of Buddha's warrior attendant, the diamond segment that can prevent high rigidity is with hard, crisp be ground that " firmly " bumps " firmly " between the surface, avoid the defectives such as polishing scratch that may occur, the ground effect of realizing ideal.Reach the characteristics that both can bring into play diamond segment grinding efficiency height, long service life, guaranteed the quality and the effect of grinding again.
The shore hardness of the rubber layer in the utility model is between 70～95, and it is cut in the process at mill cutter head is played strong supporting role.In the converted products process, cutter head can be given full play to the elastic reaction of rubber in rubber layer, avoids when unexpected vibrations are arranged, and the phenomenon that produces cut because cutter head is harder on the processing object surface takes place.Simultaneously, rubber layer has certain support strength, can realize the grinding of cutter head to processing object: for the concave-convex surface part of processing object, processing puts in place easily, and has also improved the chip removal ability, has saved water consumption.
The utlity model has low cost of manufacture, characteristic of low energy consumption.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Fig. 2 be among Fig. 1 A-A to the sectional structure schematic diagram.
Fig. 3 is the sectional structure schematic diagram of the another embodiment of the utility model.
Fig. 4 is the sectional structure schematic diagram of another embodiment of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, this composite diamond abrading block comprises cutter head 1 and holder 3, and cutter head 1 is the diamond segment of metallic bond combination, and this cutter head 1 is embedded in the rubber layer 2, and the shore hardness of rubber layer 2 is 70～95.Rubber layer 2 is arranged on the holder 3.Cutter head 1 is more than one, is distributed in the rubber layer 2.The bottom of cutter head 1 passes rubber layer 2 backs and joins with holder, sees Fig. 2, perhaps, is provided with rubber layer 2 between the bottom of cutter head 1 and the holder 3, sees Fig. 3 and Fig. 4.The cross section of cutter head 1 can be triangle, quadrangle, pentagon, hexagon or polygon, has provided tetragonal structure among the figure.
