Description

Multi-angle composite chip breaker alloy blade Technical Field The utility model relates to an alloy blade, in particular to a multi-angle composite chip breaker alloy blade, and belongs to the technical field of milling cutters. Background In the field of metal cutting machining, alloy inserts are used as key components, and the performance of the alloy inserts has a crucial influence on machining quality, efficiency and cost. In the prior art, as disclosed in the publication No. CN208034884U, the wear-resistant alloy head is adopted as the blade edge of the blade, so that the wear-resistant capability of the blade is improved, the service life is prolonged, the use cost is reduced, and the alloy head is only arranged at the cutting edge part, so that the wear-resistant alloy material is less in use amount and lower in manufacturing cost. The alloy head is tightly contacted with the Chinese character 'zhu' shaped end face of the cutter head body and is welded and connected, the lower end face of the alloy head is welded and connected with the cutter blade matrix, and the firm connection between the alloy head and the whole structure of the cutter head body and the whole structure of the cutter blade matrix are ensured, but the cutter teeth of the alloy cutter blade in the prior art adopt an integrated forming structure, and the structure can ensure certain strength and cutting performance in the initial use process, but has obvious defects. Once the cutter teeth are worn out due to long-time friction with the workpiece and bearing cutting force in the cutting process, the cutter teeth and the blade body cannot be separated, and the single worn cutter teeth cannot be replaced in a targeted mode, so that the whole alloy blade can only be abandoned, and the resource waste and the processing cost are greatly increased. Disclosure of utility model The utility model aims to solve the problems that the blade teeth of the blade are inconvenient to replace and the scrap treatment effect is poor in the processing process.
