A circular groove powder precision spreading device

Abstract

A circular groove powder precise material spreading device mainly comprises a micrometer, a rotary arm, a material spreading rod, a carrier ring, a mold outer ring, a mold middle ring, a mold inner ring and a shaft core, wherein the mold outer ring is matched with the outer surface of the mold middle ring; the outer surface of the mold inner ring is matched with the inner surface of the mold middle ring; the inner surface of the mold inner ring is matched with the outer surface of the shaft core; a main shaft is arranged at one end of the micrometer and matched with the shaft core; one end of the rotary arm is installed on the micrometer, and the other end of the rotary arm is provided with the material spreading rod; and the carrier ring is installed on the micrometer and located below the rotary arm. The circular groove powder precise material spreading device can precisely control the material spreading process and provide a material spreading precision standard, so that the material spreading process is further quantified and standardized, the precision level and the production efficiency of the production link are improved, it is ensured that the internal density of a pressed finished grinding wheel is uniform, structural strength is consistent, the mechanical property is stable, the service life of the grinding wheel is prolonged, and meanwhile abrasion to a mold in the production process is lowered.

Description

technical field [0001] The invention relates to the field of powder leveling devices, in particular to a circular groove powder precision spreading device. Background technique [0002] At present, the powder spreading device is mainly used for spreading the round grinding wheel powder. In the process of grinding wheel production, material spreading is a key link. Only by ensuring that the material powder in the circular groove is even and smooth can the pressed grinding wheel have uniform internal density, consistent structural strength, and smooth upper and lower surfaces. Currently, there are two methods of amortization: [0003] Manual spreading: This is the main method of powder spreading at present, but the effect is not ideal. First of all, the flatness of the spread is poor, resulting in uneven internal density and structural strength of the grinding wheel after pressing. At the same time, the parallelism of spreading materials is poor, which leads to wear and tea...

[0003] Manual spreading: This is the main method of powder spreading at present, but the effect is not ideal

First of all, the flatness of the spread is poor, resulting in uneven internal density and structural strength of the grinding wheel after pressing

At the same time, the parallelism of spreading materials is poor, which leads to wear and tear of the mold during the pressing process and reduces the service life of the mold; secondly, the production efficiency is low, manual feeding and spreading are slow, and the standardization of the spreading process cannot be guaranteed

[0004] Mechanical automatic flattening: It is mainly used in industrial production, and currently there are few manufacturers. Although this method has high production efficiency, it cannot accurately control the flatness of the material surface and the parallelism of the upper and lower surfaces of the grinding wheel, and cannot measure the thickness of the material in a timely manner. Complete leveling while ensuring the leveling accuracy without generating residual material
