Description

Technical Field

[0001] The utility model relates to the technical field of forming molds for triangular ring accessories used in marine mooring operations, and particularly relates to a forging forming mold for triangular rings suitable for production by an electro-hydraulic hammer. Background Art

[0002] In marine mooring operations, due to its three-way guiding property, the triangular ring has become one of the commonly used mooring chain connectors, and can replace accessories such as round rings and vertical rings. It has comprehensive mechanical properties such as high strength, high toughness, wear resistance, and corrosion resistance, and can meet any harsh working conditions. The production method of the triangular ring is generally to machine the forged cylindrical blank, then bend it into a triangle through a bending mechanism, and finally produce the finished product by the method of burning and welding. Since the triangular ring has a simple structure and a large demand, the process of producing the triangular ring by this method is complex and the efficiency is low. Therefore, a special forming mold suitable for an electro-hydraulic hammer is required to forge and produce it, ensuring that the forged triangular ring meets the shape and size requirements, and eliminating steps such as machining and bending, so as to achieve the purpose of improving production efficiency and saving materials.
