Description
Technical field
The present invention relates to the diamond abrasive grinding tool and make the field, refer in particular to a kind of be used to the produce diamond grinding material sequential arraying system of saw blade tip and thin-walled drill bit and the technology of arranging.
Background technology
Nonmetal fragile materials such as granite, marble, concrete, pitch are the exemplary that adopts diamond saw blade cutting or diamond core drill bit punching.Diamond saw blade has the cutting lay of diamond abrasive on the saw bit matrix periphery.The sawing cutter head is usually by diamond particles with control adamantine metal matrix and form.At present, the production technology that diamond saw blade generally adopts: metallic bond (as iron powder, copper powder, glass putty, nickel powder, cobalt powder etc.) is added certain density diamond, adopt the mode of mechanical batch mixing, diamond and metallic bond are mixed, carry out base and sintering in the mould of packing into.There is following problem in this technology: (1) mechanical batch mixing can't guarantee that diamond abrasive evenly distributes in metallic bond, cause some regional diamond abrasive excessive concentration, and some zones are low excessively, some no diamond abrasives in zone; (2) because of the diamond abrasive skewness, saw blade cutting usefulness descends, and the zone cutting resistance that diamond abrasive concentration is high is big, and smear metal is easily stopped up, and cutting efficiency is low.In the rare district of diamond, effectively sawing of diamond, because it is excessive to bear live load, impulsive force is big, diamond is easy to broken and comes off.There is not adamantine zone, the bond quick abrasion, the cutting resistance is big; (3) because of the cutting resistance is big, the cutting temperature height, bond and diamond are easily burnt.In a word, unordered the arrange problems such as often causing saw blade cutting efficiency low, cutting life-span weak point, cut quality difference of diamond abrasive in cutter head.After adopting granulating process, (the diamond core drill bit production technology roughly the same) though the distribution of diamond abrasive makes moderate progress, still can not tackle the problem at its root.
In recent years, in the diamond tool industry, release the new technology of cutter head diamond grinding material sequential arraying, improved cutting-rate, prolonged life tools.Simultaneously, can save diamond, reduce diamond concentration, save cost.
The ARIX automatic placement system of new Korea Spro of Korea S (Shinhan) diamond industrial group exploitation, can be in cutter head the uniform sequential diamond abrasive of arranging.Its technology is in compacting carcass thin stock, goes out the hole of ordered arrangement in thin stock, then diamond abrasive is filled in the hole.This automation technolo degree height, but owing to be to arrange piecewise, production efficiency is low, and in addition, the equipment price costliness is difficult for promoting.
The Chinese emery wheel Song Jianmin doctor of company in China Taiwan at first arranges diamond order and is applied to saw blade tip, and the patented technology of its proposition (U.S.Patent6039641) is to implement the ordered arrangement of diamond abrasive with template.The first step of this method: carcass powder is mixed, add the suitable organic binder bond and the mixture of solvent, make " dough ", do straticulation by the method for roll extrusion then.Second step, make the template that has through hole by the particle diameter of diamond abrasive material and arrangement mode, the aperture is greater than single diamond particle diameter, less than two diamond abrasive particle diameters and, guarantee that single diamond enters in the pattern hole, template thickness is the 1/3-2/3 of diamond average grain diameter.In the 3rd step, diamond is distributed in the template through hole.The 4th step, remove template, the diamond in the hole drops on the surface of thin layer, forms the ordered arrangement array, and unnecessary diamond is removed together in company with template.In the 5th step, diamond is pressed in the carcass thin layer with plain plate.This technology is the ordered arrangement diamond abrasive accurately, but the manually-operated of per pass operation wastes time and energy, and efficient is low.
The patented technology (EP1208345A) that Switzerland ETH lathe and doctor G.Burkhard of working research institute propose is to utilize the gluing process abrasive material of arranging, point glue equipment is made up of storage glue bottle, glue conveying box, little metering head, when applying a potential pulse, little metering head is discharged a glue and is dripped, but ordered arrangement glue point, then diamond is spread in glue and drips, form adamantine ordered arrangement.This explained hereafter efficient is low, and a glue drips the abrasive material number that easy adhesion does not wait, the low precision of arranging.
In a word, because the grinding material sequential arraying technical research time is not long, obviously there is deficiency in existing diamond grinding material sequential arraying technology, mainly shows aspects such as production efficiency is low, apparatus expensive.
Summary of the invention
The invention provides a kind of efficient, low-cost diamond grinding material sequential arraying system of realizing diamond grinding material sequential arraying in saw blade tip or the thin-walled drill bit.
