Description

A kind of novel Bradley corase grinding abrading block

Technical field

The utility model relates to a kind of diamond tool, in particular to a kind of novel Bradley roughly grinds abrading block.

Background technique

Diamond segment is the operative body of diamond saw blade, is widely used in processing of stone, mainly by diamond Grain, tungsten carbide and metal alloy carcass bonding agent composition.Diamond particles and tungsten carbide in cutter head are all superhard materials, are played The effect of cutting edge, metal alloy carcass bonding agent plays the role of fixed diamond, and can increase the cutting of diamond segment It effect and prolongs its service life.During cutting and polishing the stone materials such as marble, diamond segment is gradually worn out to not It can cut and discard, the valuable metals such as diamond particles, tungsten carbide and copper, iron, silver as contained by it have biggish warp Ji value, thus select easy, efficient method recycle it is significant.

The cutter head that gives up on domestic market recycles, and is all to go out diamond with pickling, seriously pollutes environment, recovery processing point is all It is individual workship's running, pickling solution, which is unable to get, to be effectively treated with regard to direct emission, polluted source；And existing method recovery value Low, only remaining 0.2 yuan/carat, the one third of only former diamond value, the heavy metal of recycling produce the diamond unit price of recycling Amount is few, inefficiency.

Utility model content

Therefore, in view of the problems of the existing technology, the utility model proposes one kind can effectively improve returning for useless cutter head Utilization rate is received, Bradley production cost is reduced, the novel Bradley for promoting Bradley grinding efficiency roughly grinds abrading block.

To realize above-mentioned technical problem, the solution that the utility model is taken are as follows: a kind of novel Bradley corase grinding abrading block, packet Matrix and the bit body on matrix are included, useless cutter head is distributed in the surface of the bit body, and the useless cutter head passes through table Face processing of rust removing.

The bit body is that diamond dust is mixed with diamond, is pelletized through reduction, useless cutter head mixing is added, through group Shaping mould is filled, is loaded through weighing, hot pressed sintering forms.Wherein, it gives up after cutter head recycling, through ultrasonic cleaning, through surface derusting, Bradley added material can be used as；The diamond that the saw blade tip of major diameter uses is 30/35 or 35/40, so its useless knife Head may be used as the additive of 36# Bradley；The cutter head of central diameter saw blade, diamond is usually using 40/45 and 45/50, and give up cutter head It can be used as the additive of 46# Bradley.

Further, each useless cutter head is in lay flat distribution.

Further, the useless cutter head is with a thickness of 15mm or less.

By using preceding solution, the beneficial effects of the utility model are: the novel Bradley designed as described above is thick Abrading block is ground, useless cutter head is distributed in bit body surface, then the cutter head working lining that gives up, the inoperative layer of useless cutter head and bit body Between working lining three, there are rate of depreciation differences, cause the novel Bradley corase grinding abrading block during the work time, cutter head Body surface will appear the irregular groove of random distribution, plays the role of holding bits, chip removal and cooling, can so substantially improve It is ground operating condition, Bradley is made to play better grinding performance, is i.e. the raising of sharpness promotes Bradley grinding efficiency；The novel cloth It draws corase grinding abrading block that useless cutter head is effectively directly realized by recycling, reduces Bradley production cost, improve economic benefit；And And useless cutter head recycles operation of only being cleaned and derusted in the process, not can cause environmental pollution, improves useless knife The environmental benefit of head reclaimer operation.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model embodiment.

Specific embodiment

Now in conjunction with the drawings and specific embodiments, the present invention will be further described.

With reference to Fig. 1, the utility model embodiment is disclosed, and a kind of novel Bradley roughly grinds abrading block, including matrix and is set to Useless cutter head 2 is distributed in bit body 1 on matrix, the surface of the bit body 1, and the useless cutter head 2 is by surface derusting Reason；Each useless cutter head 2 is in lay flat distribution；The useless cutter head 2 is with a thickness of 15mm or less.

The novel Bradley corase grinding abrading block designed in summary, can effectively improve the recovery utilization rate of useless cutter head, reduce cloth Production cost is drawn, Bradley grinding efficiency is promoted, it is practical.

The foregoing descriptions are merely the embodiment using this origination techniques content, any those skilled in the art use this wound Make done modifications and changes, all belong to the scope of the patents of this creation opinion, and is not limited to those disclosed embodiments.
