Coarse-grain ultrahard abrasive material orderly arraying device and arraying method

Abstract

The invention relates to a coarse-grain ultrahard abrasive material orderly arraying device and arraying method. The coarse-grain ultrahard abrasive material orderly arraying device and arraying method comprises an outer shell. A material storage bin is fixedly connected with the outer side of the upper end of a shell body of the outer shell. A mold plate is fixedly connected with the inner side of the upper end of the shell body of the outer shell. A mold sleeve is arranged on a base of the outer shell and located right below the mold plate. An air cylinder is arranged between a mold block and the base of the outer shell. A side opening door used for adding materials is arranged on the side face of the outer shell. The coarse-grain ultrahard abrasive material orderly arraying device has the advantages that the defects that suction needs to be conducted in a reciprocating mode, the time for releasing the abrasive materials is long and a vacuumizing device is needed in a vacuum adsorption method are overcome; the problems that only a single layer abrasive material can be arrayed and a layer of glue needs to be smeared on the surface through a mold plate method in a mechanical mode are solved; the abrasive materials can be arrayed in working layers in a multi-layer mode efficiently, rapidly and orderly.

Description

technical field [0001] The invention relates to the technical field of abrasive tool manufacturing, in particular to a device and method for orderly arranging coarse-grain superabrasives. Background technique [0002] Superhard abrasive tools with diamond and cubic boron nitride as abrasives are widely used in high-efficiency precision machining, stone, construction and other fields. Superabrasive tools generally consist of two parts: a substrate and a working layer. The working layer is made by mixing abrasives, bonding agents and auxiliary materials in proportion, and then pressing, sintering (hardening) and processing. The abrasives in the working layer made by this method are randomly distributed, and it is easy to cause uneven distribution of abrasives. In the place where there are many abrasives, the cutting force of a single abrasive is too small to make the edge difficult, which affects the work efficiency. Where the abrasive is sparsely distributed, a single abra...

Chinese Patent (Application No. 200820061656.4) "Vacuum Distributing Machine" discloses a distributing machine that adopts vacuum adsorption and installs a vibrator on the distributing template (online), but it is on the surface of a cold-pressed cutter head carcass. Apply a layer of glue, and then release the diamond that is vacuum-adsorbed on the template and fall on the carcass of the cutter head. It is necessary to apply glue to the cutter head body and then dry it. It can only achieve single-layer fabric

[0006] Chinese Patent (Application No. 201010040071.6) "Diamond Abrasive Orderly Arrangement System and Arrangement Process" discloses an orderly arrangement system using vacuum adsorption. The orderly arrangement system of the magnetic workbench can only realize single-layer cloth

The problem with this method is that the multiple insertion of the straw into the powder will affect the uniform density of the molding material.

[0010] Chinese Patent (Application No. 201210236552.3) "A Sintered Diamond Tool with Optimum Arrangement of Abrasives and Its Manufacturing Method" discloses that diamonds are arranged with a hole template, and a layer of pressure-sensitive adhesive is coated on one side of a cold-pressed cutter head carcass , and then press the diamond in the hole template into the carcass of the cutter head, this method can only achieve the arrangement of a single layer of abrasive

[0012] However, in the prior art, the vacuum suction method of the template method requires a vacuum device, and it needs to repeatedly move from the suction position to the discharge position during work. The mechanical method of the template method can only arrange a single layer of abrasives, and the efficiency of the two methods is low.
