Automatic grinding and mixing device for ultrahard material

Abstract

The invention discloses an automatic grinding and mixing device for an ultrahard material. The automatic grinding and mixing device comprises a base and a supporting barrel, wherein a cover plate is arranged at the top of the supporting barrel; a hard alloy mortar is arranged at the bottom of an inner cavity of the supporting barrel; a nut is arranged in the center of the cover plate; a screw rod is screwed in the nut; the bottom end of the screw rod extends into the supporting barrel and is connected with a rotary supporting plate; the rotary supporting plate is downwardly and fixedly connected with an upper hinge; the upper hinge is downwardly hinged with a lower hinge; the lower hinge is connected with a hard alloy grinding head; the top end of the screw rod extends out of the nut and is connected with a positive and negative rotation motor; the bottom of the positive and negative rotation motor is fixedly connected with a motor supporting plate; one side of the motor supporting plate is connected with a guide sleeve; an anti-rotation guide rod glidingly penetrates through a through hole of the guide sleeve; the bottom end of the anti-rotation guide rod is fixedly connected to the top of the cover plate. In short, the labor intensity of an worker can be reduced, an actual state of a manual grinding and mixing process can be automatically simulated, the defect of high material uniformity difference caused by the manual grinding and mixing process can be avoided, and the technical obstacle in producing high-quality diamond and cubic boron nitride polycrystalline composite sheets can be overcome.

Description

technical field [0001] The invention relates to the technical field of superhard material production, in particular to a superhard material grinding and mixing device which can be used for grinding and mixing diamond and cubic boron nitride composite sheet polycrystalline layer powder. Background technique [0002] In the field of superhard material production technology, the uniformity of the polycrystalline layer of the composite sheet is the key to ensuring the quality of the diamond and cubic boron nitride composite sheet, and the uniformity of the mixture plays a vital role in the quality of the composite sheet. At present, the powder of the polycrystalline layer of the composite sheet is manually ground, that is, the powder is put into a mortar, and the powder is ground and mixed by stirring the grinding rod by hand. The main disadvantages of this method are: 1. First, the labor intensity is high, and second, the uniformity of different times or different people's grin...

AI Technical Summary

Problems solved by technology

At present, the powder of the polycrystalline layer of the composite sheet is manually ground, that is, the powder is put into a mortar, and the powder is ground and mixed by stirring the grinding rod by hand. The main disadvantages of this method are: 1. First, the labor intensity is high, and second, the uniformity of different times or different people's grinding materials is quite different, resulting in a large difference in the quality of diamond and cubic boron nitride polycrystalline composite sheets, which seriously restricts the quality of high-grade diamond and cubic boron nitride. Research on boron polycrystalline compacts is a technical obstacle in the production of high-grade diamond and cubic boron nitride polycrystalline compacts

[0003] At present, the technical field lacks an automatic grinding and mixing device for superhard materials that can overcome the above-mentioned defects
