FIELD: metal forming.
SUBSTANCE: inventions can be used in production of anchor chains from metal wire. Automatic chain-bending machine comprises two spiral formers, made with possibility of forming chain links by screwing one spiral formed by one spiral former into another for a given number of turns. There are two wire cutting assemblies forming functional pairs with spiral formers. Method of bending involves screwing one spiral into another for a given number of turns, cutting of section of screwed-in turns of spiral with provision of its cutting off from spiral with formation of chain link. Repeated repetition of the spiral screwing and cutting step is performed to form the chain.
EFFECT: as a result, it is possible to manufacture multi-link round-link chains of anchor type with adjustment depending on the degree of density of the chain and its model.
