Forming die sleeve for super-hard grinding wheel, and die applying die sleeve

Abstract

The invention relates to a forming die sleeve for a super-hard grinding wheel, and a die applying the die sleeve. The forming die sleeve for the super-hard grinding wheel comprises a die sleeve main body in a pipe sleeve shape, and the inner wall surface of the die sleeve main body is an inner cylindrical surface; the peripheral surface of the die sleeve main body is an outer cylindrical surface,and the peripheries of the both ends of the die sleeve main body are provided with catching grooves symmetrically; and the catching grooves at each end of the die sleeve main body are distributed at intervals annularly or circumferentially. In case the inner wall of one end of the die sleeve is damaged, the die sleeve can be reversed for use after being removed from a die holder through the catching grooves; the inner wall of the reversed die sleeve is a complete inner wall which is not damaged, thereby solving the problem that the whole inner wall of the die sleeve needs to be repaired when the inner wall of one end of the die sleeve is damaged; the both ends of the die sleeve can be replaced with each other, and the utilization rate of the die sleeve is improved; and the repair cycle ofthe die sleeve is prolonged, and the manufacturing cost of the grinding wheel is reduced.

Description

technical field [0001] The invention relates to a forming mold cover for a superhard grinding wheel and a mold using the mold cover. Background technique [0002] At present, the production and preparation of superhard grinding wheels is carried out in the mold, that is, the abrasive is put in the mold first, and after the abrasive is flattened, the fiber mesh is placed on the abrasive, and then the abrasive in the mold is heated and extruded. The abrasive is pressed into a mold to form a finished grinding wheel. In this process, in order to ensure the precision of the grinding wheel pressing, it is necessary to keep the inner wall of the mold sleeve smooth, and it is necessary to remove the mold from the conveying line from time to time, and to grind and repair the inner wall of the mold sleeve. However, in the existing moulds, the mold casing is not removable or fixed on the mold base, and in the spreading process, the spreading scraper needs to be in continuous rigid con...

Problems solved by technology

However, in the existing moulds, the mold casing is not removable or fixed on the mold base, and in the spreading process, the spreading scraper needs to be in continuous rigid contact with the inner wall of the upper section of the mold casing, which makes the mold casing The inner wall of the upper section is scratched by the spreader scraper. At this time, the inner wall of the mold sleeve needs to be trimmed. The existing trimming is to remove the entire mold from the conveying track for trimming. This trimming method will make the intact part of the inner wall of the lower section of the mold sleeve are also trimmed, resulting in increased die wear and reduced service life
