Description
Technical field
The utility model relates to grinding technique fields, more specifically refer to a kind of abrasive disk.
Background technique
Abrasive disk is the polishing tool in stone sander tool, and traditional abrasive disk includes mounting disc, matrix and cutter head,
Wherein mounting disc and matrix are cast member, and cutter head is to agglomerate made of the mixture sintering of diamond dust and alloy powder,
Several cutter heads are connected to the lower end surface of matrix by way of high-frequency welding, then by bolt from the bottom up by the fixed peace of matrix
The upper surface of lower end surface loaded on mounting disc, mounting disc is then bolted in the rotary shaft for being installed on grinding machine, will be whole
A abrasive disk is assemblied in grinding machine so that cutter head is directed downwardly, carries out corase grinding processing to the stone material placed on lower work platform.But
Traditional abrasive disk has the following problems: (1) raw material of conventional matrix are wastes of iron and steel, using turning over after coal or electro-smelting
Sand casting, needs to consume a large amount of coal and electric energy, generates a large amount of exhaust gas waste residue, and scald thing in production process frequent occurrence
Therefore product flatness is inadequate, many waste products, substandard products occurs.And conventional matrix is easy cracking, and heavier-weight is unfavorable for loading and unloading
Abrasive disk.(2) it since Buddha's warrior attendant agglomeration head can not be directly welded on casting, is fixed using high-frequency induction welding technique, this
Although kind of mode fixation, its working efficiency is lower, higher cost.And in tool bit abrasion or after falling off, due to
Conventional matrix is easy cracking, and matrix can not be utilized repeatedly, and maintenance cost is higher.
To solve the above-mentioned problems, application publication number is public in the Chinese invention patent application document of 107498454 A of CN
The manufacture craft for having opened a kind of abrasive disk (ties traditional cutter head made of the mixture sintering of diamond dust and alloy powder
Block) and tagger connected by way of sintering, formed compound tool bit；It is with the mode of butt-joint that several compound tool bits are solid one by one again
It is scheduled on the salient point of irony pedestal.Irony pedestal with compound tool bit is fixed on to the lower end of fixed disk using Shi Zaiyong screw
Face serves as conventional matrix with fixed disk and irony pedestal, is bolted and is installed on mounting disc, and last mounting disc passes through bolt
It is fixedly installed in the rotary shaft of grinding machine, entire abrasive disk is assemblied in grinding machine so that compound tool bit is directed downwardly.It is this
Mode although allow fixed disk can reuse (after tool bit abrasion, only need to by another irony base new and with compound tool bit
Seat is replaced to fixed disk), but still have the following problems: (1), compared to traditional abrasive disk, the component of entire abrasive disk
Quantity increases, and weight becomes larger, and handling are got up more troublesome.Due to passing through bolt between irony pedestal, fixed disk and mounting disc
It is connected and fixed, there are multilayer bolt connecting modes, are easy to appear loosening between each other, abrasive disk is when polishing stone material, each component
Between be easy to shake, vibrate entire abrasive disk, be easy to accelerate the loss of compound tool bit and other parts, make polishing quality
(flatness of stone material buffed surface) reduces.(2) tagger is to play the role of butt-joint to connect with irony pedestal, and thickness is about
2.0mm to 2.5mm.It after compound tool bit abrasion, due to the thinner thickness of irony pedestal and tagger, can not reuse, tie up
It is still not low to accomplish this.(3) by the tagger butt-joint of compound tool bit when irony pedestal, due to diamond dust and alloy powder
Mixture agglomeration electric conductivity it is poor, cause the butt-joint electric current between iron plate and irony pedestal to become smaller, be easy to appear composite cutter
The welding is not firm or even rosin joint and other issues for head, to influence the service life of entire abrasive disk.(4) it still needs to produce
It casts with using into fixed disk and mounting disc, is easy to cause larger pollution to environment.
