The invention discloses an automatic wire transporting and straightening device of a spring machine. The automatic wire transporting and straightening device comprises a rotating roller arranged between two brackets, wherein rotating shafts in which through holes are formed in axes are respectively and fixedly connected to two ends of the rotating roller; a bearing seat is arranged between each rotating shaft and the corresponding bracket; one of the rotating shafts penetrates through one end of the corresponding bracket to be linked with a driving motor through a belt; the inner part of the rotating roller is hollow, and a plurality of fixing rods which are arranged in a staggered manner are uniformly arranged on a housing of the rotating roller in a penetrating manner; hexagonal nuts arerespectively arranged on two sides of the housing of the rotating roller, of each fixing rod; a wire transporting mechanism capable of automatically adjusting clamping force on steel spring wires isarranged at one end in the rotating roller, of each fixing rod; the wire transporting mechanisms and the through holes in the rotating shafts are on the same plane; and the same baffle mechanism is arranged at the bottoms of the two brackets. The automatic wire transporting and straightening device disclosed by the invention has the following beneficial effects that during damping, the clamping force on the steel spring wires is automatically adjusted, so that operations of wire transporting and straightening can be performed at the same time.
