A die-casting device for superhard grinding wheel with ordered micro-groove structure

Abstract

The invention discloses a die-casting molding device for superhard grinding wheels with an ordered micro-groove structure, which specifically includes a mold, a turntable, a main shaft, a heating wire, a temperature sensor, an insulation layer, a motor, and a belt; the driving motor rotates the main shaft through the belt, and the upper end of the main shaft It is connected with the turntable, so as to drive the turntable to rotate and generate centrifugal force; the mold is installed on the turntable, and the mold includes a lower mold and an upper mold. The sheets are arranged, and the mold groove between the mold sheets corresponds to the position of the grinding wheel grinding block; the outer surface of the mold is covered with heating wire and insulation layer in turn, and a temperature sensor is installed in the mold to detect the internal temperature of the mold, and the temperature signal It is transmitted to the computer for analysis and display, and the opening and closing of the heating wire switch is controlled in real time so that the internal temperature of the mold reaches the required setting temperature for die-casting. The invention has a simple structure and can efficiently prepare a grinding wheel with uniform abrasive distribution.

Description

technical field [0001] The invention relates to a die-casting forming device for a superhard grinding wheel, in particular to a die-casting forming device for a superhard grinding wheel with an ordered micro-groove structure. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. It rotates at high speed when used, and can perform rough grinding, semi-finish grinding, fine grinding, slotting and cutting off the outer circle, inner circle, plane and various profiles of the workpiece. Wait. Superhard grinding wheels are widely used in national defense, aerospace, chip manufacturing, engineering equipment, automobile industry and other fields, but the manufacture of superhard grinding wheels has always been one of the problems that need to be solved urgently. [0003] The preparation method of superhard grinding wheels is usually cumbersome, and the superhard abrasives are often unevenly distributed, especially for superha...

AI Technical Summary

Problems solved by technology

However, the abrasives of the grinding wheel prepared by this device are usually unevenly distributed and lead to increased wear of the grinding wheel, and the temperature required for die-casting cannot be detected and controlled in real time, resulting in abrasive grain damage or insufficient abrasive grain bonding strength, especially difficult to achieve an extremely complex surface structure.
