Die-casting forming device for superhard grinding wheel with ordered microgroove structure

Abstract

The invention discloses a die-casting forming device for a superhard grinding wheel with an ordered microgroove structure. The die-casting forming device specifically comprises a die, a rotary table,a main shaft, an electric heating wire, a temperature sensor, a heat preservation layer, a motor and a belt; a driving motor rotates the main shaft through the belt, and the upper end of the main shaft is connected with the rotary table to drive the rotary table to rotate and generate centrifugal force; the die is installed on the rotary table and comprises a lower die body and an upper die body,the center of the lower die body protrudes and is matched with a grinding wheel hub, the upper die body is provided with a large number of orderly-arranged sheets corresponding to grinding wheel microgrooves, and die grooves between the die sheets correspond to grinding wheel grinding blocks in position; and the outer surface of the die is sequentially coated with the electric heating wire and the heat preservation layer, the temperature sensor is installed in the die and used for detecting the internal temperature of the die and transmitting temperature signals to a computer for analysis anddisplay, and on-off of an electric heating wire switch is controlled in real time so that the internal temperature of the die can reach the set temperature needed by die casting. The device is simplein structure and can efficiently prepare the grinding wheel with uniformly distributed grinding materials.

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...

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.
