Abstract

The invention discloses a cemented carbide plate with internally threaded holes and a manufacturing method thereof. The cemented carbide plate with internally threaded holes includes a cemented carbide plate, a through hole and a tooth cover, and the cemented carbide plate is provided with a through hole , the braces adapted to the shape of the through hole are seamlessly set on the hard alloy plate, and the middle part of the braces is provided with an internal threaded hole. The invention solves the problems of high processing cost and long processing time of the conventional hard alloy plate with internal thread holes.

Description

technical field [0001] The invention relates to the technical field of hard alloy production, in particular to a hard alloy plate with internal thread holes and a manufacturing method thereof. Background technique [0002] The traditional method of machining the inner threaded hole of cemented carbide firstly grinds the outer circle and two planes of the cemented carbide blank, and then finely grinds the inner hole. The purpose is to pre-process the crest of the internal thread. The texture limits the processing of internal threads by turning. In recent years, domestic researchers have proposed the method of EDM internal thread of cemented carbide. For example, Chinese patent CN104668682B discloses a processing method and tooling for EDM internal thread of tungsten carbide product. However, the existing processing method still has the disadvantages of long processing time and high processing cost, especially for processing multiple internal threaded holes, the above disadva...
