Hexagon edge cutting type plays the role of edge cutting and shaping in the forming process of cold hexagon bolt.At present, the domestic production of hexagonal cut edge model, especially large specifications (M12 above) stainless steel bolt mold, compared with foreign countries, its service life is generally lower, so most of the domestic standard product manufacturers on this kind of mold is still dependent on imports.The factors that affect the service life of hexagon edge cutting die mainly include die structure, die material, machining and the conditions of wenzhou edge cutting die, among which die structure and die material are the important factors.Through the analysis of the force of the mould, the author chooses the measures such as the structural design of the component and the mould again, the service life of the mould is equal to that of the same kind of foreign mould, and the result of shandong edge-cutting mould is better.The service conditions and failure forms of hexagon edge cutting cold bolt forming process include cutting material, prefabricated parts, seam and edge trimming.In order to analyze the stress of hexagon edge-cut mode during operation, the load of M16 edge-cut mode was tested by CRAS random signal and vibration analysis system.
